History of Ashok Leyland: Ashok Leyland was urge for self reliance industry felt by India’s first Prime Minister Pt.Jawhar Lal Nehru, persuaded Mr. Raghunandan charan, an industrialist to enter automotive manufacture. In 1948,Ashok motors was set up but was then in Madras,for the assembly of Austin cars after that in 1955 company’s name and luck changed by equity participation by British company Leyland and Ashok motors get a new brand “ASHOK LEYLAND” the manufacture of commercial vehicles. Since Ashok Leyland has been a foremost existence in India’s commercial vehicle industrial. With a convention of technological leadership achieved by tie ups and collaboration with international technology leading organization through enthusiastic in-house research and development it set up its existence in Indian and Foreign market.

Admittance to global technology and equipment enabled the company to set first with technology in full Air-brakes, Power-Steering, and Rear engine buses etc, Ashok Leyland pioneered all these concepts. Responding to the operating conditions and practice in the country, the company made its vehicle strong over engineering then with extra metallic Muscles

Ashok Leyland vehicles have built repute for reliability and austerity. The 5,00,000 Vehicles put on the roads have considerably eased the additional pressure placed on road transportation in independent India.

Ashok Leyland buses are used by four for out of five most populated states as there state transportation corporation Vehicles.

Some of them like Double decker and vestibule buses are unique models trom Ashok Leyland taylor made for high density routs. The company’s products are inherent to Indian lives Ashok Leyland dominates in city passenger transportation with specialized high capacity buses such as the double decker and vestibule bus for which the company is the only Indian source.

Ashok Leyland supplies a host of modern special purpose to India defense sector. This includes stallion 4x4s forming the back bone of Indian army’s logistics operations, now being assembled with in the defense sector through a technology transfer agreement. The stallions left an indelible mark for reliability during the Kargil conflict. When India and Pakistan open there common gate at baga, Ashok Leyland buses were the choice for this prestigious cross border passenger service.

Ashok Leyland has maintained its technology even as it offers the most comprehensive range of model configurations in its class, offering the costumers the closest fit with his unique requirements. A pioneer in alternate fuels, Ashok Leyland made India’s first CNG powered buses in 1997. In 2002, India entered another frontier technology Ashok Leyland developed India’s first hybrid electric bus in a partnership with the Govt sector.

In 1987, the overseas holding by land rover Leyland international holdings limited was taken over by a joint venture between the Hindu group, the known residential Indian transport group and IVECO. (Since July 2006, Hinduja group is 100% holder of LRLIH)

In the journey towards global standard of quality of Ashok Leyland reached a major milestone in 1993, when it becomes the first Indian history to win the ISO-9002 certification. The more comprehensive ISO-9001 certification came in 1994, QS-9000 in 1998 and ISO-14001 certification for all vehicles manufacturing units in 2002.It has also become the first Indian auto company to receive the latest ISOTS-16949 corporate certification (in July 2006) which is specified to the auto industry.

ASHOK LEYLAND DEPARTMENTS

 PRODUCTION DEPARTMENT:

This department handles all the plan work for production. This department is responsible for all the production and its process going at assembly line and also the PDI (pre delivery inspection)

They deal with all the workers to get the work output from them for production. They decide which model is to be assembled according to the availability of material and demand of production.

5

 PERSONNEL AND ADMINISTRATION DEPARTMENT :

This department has to perform the no. of functions such as all kind of recruitments like executives, managers and workers. They conduct various types of tests and interviews for vacancy lying in the organization or at demand of managers.

They also take care of medical facility, canteen facility, library and security too. They are also responsible for the discipline in the plant. Mainly they deal with all the personal behaviors of employees. They arrange seminars and other motivating events for the employees. They also conduct cultural events and get together, in which they include the family members of the employees for giving a change from routine work.

They also record all individual working record in organization. They deal the relations with other organizations and institutes. This department is known as human resource department in other organization.

 QUALITY CONTROL DEPARTMENT:

This department is responsible for the quality of products and parts whatever they sell or purchase. The quality checking is done in three processes, which are given as follows:

1. Incoming material inspection 2. In – process inspection 3. Final inspection There is a GR & D (goods receipt and dispatch) section, which receives goods, and QC department inspect them and ensure the quality as per the recommended standards and then send them to store.

5

For in – process inspection they use one chassis card in which the worker check whether all things has been done which he had to do and then do his signature in the card. This is known as self – certification.

When the chassis become off track to the assembly line then the chassis goes for a road test. The defects and shortcomings in the chassis are noted such as noise, smoke, driving control etc. then an inspection of chassis takes place at PDI and then all the defects are noted and are rectified. After that the chassis is passed to sales department by QC department.

 PPC DEPARTMENT:

Production planning and control department is known as PPC department. This department control GR & D section and storerooms. They receive the goods coming from the factories. Then according to the vouchers, counting of parts is done. They prepare a daily report of goods receive and send it to finance department for further procedure. They allot part number for the parts and parts are arranged according to the part number in the store – room. They keep all the records of store – room. Monthly counting of parts is also done.

PPC department does whole of the material – planning for production. Also they make available all the material required for the production at the time of production at all the stages. Two bin – system is being used here for the supply of material at all the stages. This is like there will be two bins at a stage and, as one becomes empty that will be replaced by a bin full of the material.

 UNIT PLANNING DEPARTMENT:

5

This department basically does the planning work. They are given the project of some new units to be prepared in the plant for which they plan the appropriate place for installation of the new unit, the approximate duration of completion of project, cost – estimation and benefits of the installation of new unit.

Presently they are taking care of new rear axle assembly conveyor line project being installed in shop-2, paint booth for body painting of foton bus in shop-5.

 PRODUCTION SERVICES DEPARTMENT:

This department is also known as maintenance department. They are responsible to provide the services required for the production and also for the maintenance of all the equipments being used. They rectify the problem occurred in the equipment at the time of break down of some equipment. For example the equipments are bolt – tightening machine, impact wrench, forklift, overhead crane, conveyor, compressor, generator and electricity, oil – filling machine, greasing machine, pneumatic devices, lightning devices and fans etc.

They do regular checking and maintenance. A formal calling system is being used. Whenever the maintenance is required at assembly line or some break down occurs in machine, a person press the button and the maintenance department will be informed by the system. Then the person from maintenance section will come at the location and will solve the problem.

They also take care of horticulture in the plant. This makes the beauty of the plant and makes the plant environment – friendly green plant.

They are responsible for those instrument and services provided by them to achieving the production.

5

 PURCHASE DEPARTMENT:

Raw material is very important for the production. Purchase department purchases all the raw materials from various dealers and companies. They decide which material should be bought from which company.

They also look at the cost of material to be purchased and the transportation charges. It is better if the material is coming from a place nearer to the plant because the transportation cost will be reduced.

They also the firm to sell the scrap items of iron, wood etc. the tender will be given who ever will pay more.

They also hire the contractors from the market by tendering to manage many works in plant like material unloading, transportation, and construction.

 FINANCE DEPARTMENT

This department takes care of all financial things of plant. They keep record of all the salaries and alliance of the employees, the money spent on purchasing the things for plant, the money earned by the sale of products and other financial activities. They prepare monthly and annual budget of the plant.

Also they monitor the attendance of employees by an electronic card punching attendance system. All the employees are provided with an electronic card, which is punched in the card-punching machine at the time of entering the plant and at the time of leaving the plant. The machine will note the time of punching and thus the department gets the data.

5

 SALES AND MARKETING DEPARTMENT:

Products are made in the plant and they need to be sold for the customers. This department takes care of all the marketing activities. After the product is passed from QC department, sales and marketing department keeps all the products at R.S.O (regional sales office) with safety. The vehicle is kept in the RSO after fitting the heat guards, warning triangles, RUPD (rear under protection device) and canopy as per the government rule. Then at demand and requirement the products are sent to the dealers.

They look at the demand of product in the market

and the customer’s feedback about the product.

They also provide the training for servicing of the product.

They send their report that in what amount market has demand to production department so that they can decide the amount of production that they can.

 PDI (PRE DELIVERY INSPECTION):

It comes under the production department but it has its much utility that it has an important role in the production.

The vehicle coming from assembly line is not perfect in quality. It has many defects. So the chassis is inspected, faults are arrested in this section and all the defects and faults are noted. The chassis comes into PDI section after road – testing.

5

Then all the defects and faults found in the chassis are rectified using necessary tools and items. Then the chassis is painted in paint booth and if there is any dent on the chassis FES then it is removed. And finally passed to sales department. The chassis passed from PDI is fault free and prefect in quality.

Painting of the chassis is also done under this department.



GR&D (Goods Receive and Dispatch) :

This department is providing for giving their services when the goods are received and dispatch in the plant as a material from out side and when it dispatch out side the plant.

This basically gives for their quality and amount assuring.

STUDY OF WHEEL ALIGNMENT Wheel Alignment should be checked whenever new tires are installed, suspension components installed, when the vehicle has encountered a major road hazard or curb and any time unusual tire wear patterns appear. Wheel Alignment is the Measurement of complex suspension angles and the adjustment of a variety of suspension components. It is a suspension-tuning tool which greatly influences the vehicle's handling and tire wear. Wheel alignment consists of adjusting the angles of the wheels so that they are parallel to each other and perpendicular to the ground, thus maximizing tire life and ensures straight and true tracking along a straight and level road. The primary static suspension angles that need to be measured and adjusted are caster, camber, toe and thrust angle. The following are definitions Conditions and Possible Causes of each angle and its influence on a vehicle and its tires. Wheel Alignment : Abstract of These Fundamental Elements

WHEEL ALIGNMENT

5

CASTER

CAMBER

TOE

THRUST

CASTER: Caster is the angle between an imaginary line drawn through the upper and lower steering pivots and a line perpendicular to the road surface (viewed from side of vehicle). If the top of the line tilts rearward, the vehicle is said to have “POSITIVE” caster. If the top of the line tilts forward, the vehicle is said to have “NEGATIVE”caster. Positive caster can also be defined as when the spindle is tipped so that the pivot support centerline intersects the road surface at a point in front of the initial tire contact. Negative caster would then be the center line intersection to the road surface behind the initial tire contact.

Purpose: The King Pin is usually set so that tire contact point with the ground is behind the intersection point between the steering axis and the ground

5

This forces the tire to always go ahead.

This improves Straight-Ahead Drivability, and improves Handling/Steering Return.

Characteristics: Larger Caster Angle -

Merit : Better Straight-Ahead DrivabilityTire contact point Caster Trail Intersection point Better Steering Wheel Return with the ground between steering

Demerit: - Heavier Steering Camber Angle The camber angle will affect the wear on the inner or outer edge of the tire. Camber is the inclination of the centerline of the wheel from the vertical as viewedfrom the front of the vehicle. Camber angle is measured in positive or negative degrees. Positive camber is the outward tilt of the top of the tire. Negative camber is the inward tilt of the tire at the top. If a tire was absolutely vertical, the degree of camber would be zero. Unlike the caster angle, camber will change with vehicle load and ride height. 5

With the weight of thedriver in the vehicle

Purpose: 1. Improve Steering Control Performance (which is related with King Pin Offset). 2. Improve Cornering Performance.

Characteristics: Larger Positive Angle (King Pin Offset is smaller)

Merit :Better Handling Control Better Handling/Steering Return

Demerit :Reduced Cornering Capacity * Larger Negative Angle (King Pin Offset is larger)

Merit :- Better Initial Handling Response Better Cornering Capacity

Demerit :- Reduced Handling Control ( Cornering Capacity – Safety on Cornering Speed or Radius)

Thrust Angle Thrust angle is the direction that the rear wheels are pointing in relation to the centerline of the vehicle.

5

The vehicle will "dog track" if the thrust angle is not zero and the steering wheel will not be centered.

The best solution is to first adjust the rear toe to the centerline and then adjust the front toe. This is done during a all wheel alignment if the rear toe is adjustable. If the rear is not adjustable, then the front toe must be set to compensate for the thrust angle, allowing the steering to be centered. If the thrust angle is not correct on a vehicle with a solid rear axle, it often requires a frame straightening shop to correctly reposition the rear axle. A vehicles with independent rear suspension, the toe must be adjusted individually until it has reached the appropriate setting for its side of the vehicle, incorrect thrust angle is often caused by an out-of-position suspension or incorrect toe settings. So in addition to the handling problems that are the result of incorrect toe settings, thrust angles can also cause the vehicle to handle differently when turning left vs. right.

5

Toe-In and Toe-Out Toe is the difference between the leading edge (or front) and trailing edge (or rear) of the tires. Toe-in is the measurement in fractions of an inch, millimeters or decimal of degrees that the tires are closer together in the front than they are in the back. Toe-out is the same

A<

B = Toe-In A > B = Toe-Out

measurement, except the tires are further apart in the front than in the rear. Some manufacturers measure the angular change from straight-ahead in degrees. Slight toe-in is preferred to toe-out on most vehicles because steering is aligned while the vehicle is stationary. is moving, linkage components flex causing a change in alignment angles. The usual tendency is for the tires to turn outward while the vehicle is in motion, so most vehicles are designed with a static toe-in setting.

Purpose :By setting the most appropriate Toe condition with the correct Camber condition, driving performance is well arranged to : 1. Improve Straight Drivability. 2. Improve Handling Response.

The Case. According to the Camber condition, the Toe-In or Toe-Out settings are adapted as follows to : • avoid irregular wear, and • balance side forces by Camber and by Toe for high speed driving performance.

5

Scrub Radius Scrub Radius is the distance between the extended centerline of the steering axis and the centerline of the tire where the tread contacts the road. This distance must be exactly the same from side to side or the vehicle will pull strongly. If the steering centerline is inboard of the tire centerline, the scrub radius is positive. If the steering centerline is outboard of the tire centerline, the scrub radius is negative. Rear-wheel drive cars and trucks generally have a positive scrub radius while FWD cars usually have zero or a negative scrub radius because they have a higher Steering Axis Inclination (SAI), angle. Using different wheels other than stock can alter the scrub radius.
