Function and Control System (Continue)

Description of the function The VOITH Retarder 120 is a powerful hydrodynamic continous brake of compact design for buses and commercial vehicles of the medium range. The VOITH Retarder 120 is mounted between the gearbox and the rear axle of the vehicle. The retarder braking torque is sustained even when gear changes are made. The switched-on retarder will not secure a parked vehicle. In the event of a retarder failure or when the temperature limit is effective, the service brake must be used to regulate the vehicle speed. A retarder stage switch (16) with a maximum of 5 switching stages is used to control the VOITH Retarders 120. A special version combines the retarder stage switch (16) with ABS, a 3-stage pedal-operated brake valve or a service-brake pressure switch. The following variaties in operation are available: Operation with function ,,Constant speed" The retarder is operated by a 5-stage retarder stage switch. When the retarder stage switch (16) is shifted to position 1, the „Constant Speed“ function is activated. The present speed is memorized and the retarder holds the vehicle to this speed downhill within the limit of the maximum braking torque. If the retarder is switched off (0 position), or switched to braking stage (position 2 to 5), the memorized constant speed is deleted. If the constant speed function is re-activated, the new present speed is memorized. When the retarder stage switch is shifted to position 2 to 5, braking stage 1 to 4 is energized. Maximum braking torque is obtained when the retarder stage switch is in the maximum position.

Function and Control System (Continue)

Description of operation of retarder R 120 with digiprop control system As a special version, the control system is available with push button operation for constant speed. The retarder is operated in this case by a 4-stage retarder stage switch. When the push button is pushed in any position of the retarder stage switch, the momentary speed is transferred to memory. In the 0 braking stage, this transfer to memory takes effect and the retarder holds the vehicle speed downhill constant within the limits of the maximum braking torque. Another push on the push button in any switch position will delete the speed data.

c

a

b

On a downhill run with „constant speed“ operation, the vehicle can be slowed down within the limits of the maximum braking torque and the temperature limit, for an obstacle ahead (e.g. bend) by shifting to braking positions 1 to 4. If the retarder stage switch is then shifted to position 0, the vehicle accelerates to the speed previously transferred to memory. The control medium for the Voith Retarder 120 is compressed air, which is taken from the air tank for auxiliary equipment on the vehicle. When the retarder stage switch (16) is operated, an input signal is fed to the control unit (2). From this input signal, the control unit (2) provides a control current which flows to the proportional valve (21). The proportional valve (21), depending on the magnitude of the control current, provides a constant-air pressure p y on the oil sump (43).

The hydrodynamic principle a Rotor (46) b Stator (44) c Oil flow

The constant-air pressure p y in the oil sump (43), depending on the operating conditions (prop shaft speed), forces a certain quantity of oil into the working chamber between rotor (46) and stator (44).

Function and Control System (Continue)

The rotor (46) is connected with the retarder drive shaft, the stator (44) is stationary with the retarder housing. The rotation of the rotor sets the oil in motion and circulates it in a closed circuit between the rotor (46) and stator (44). The reduction of the velocity of the oil flow in the chambers of the stator (44) leads to braking of the rotor (46) and consequently to braking of the vehicle. During braking, the kinetic energy of a deceleration is transformed into heat. To dissipate this heat, part of the circulating oil is pumped continuously by the rotor (46) through the heat exchanger (3300) and via filling ducts to join the circulating flow again. In the heat exchanger (3300), the heat energy of the oil is transferred to the cooling water of the vehicle and dissipated via the vehicle radiator to the ambient air.

2.2

Function and Control System (Continue)

Temperatur pick-ups, water (19), oil (20) The temperature pick-ups are installed in the cooling system of the vehicle (cooling return circle from the retarder to the the heat exchanger) and in the retarder oil duct and transmit signals on cooling water and oil temperature to the control unit (2). To prevent the temperatures preset in the control unit (2) for water and oil being exceeded, the retarder braking torque is limited to protect the vehicle cooling system and the retarder. The constant-air pressure p y is limited. The braking torque and consequently the heat generated are reduced until a balance is obtained between the braking energy of the retarder and the amount of heat which can be dissipated by the vehicle cooling system. If the cooling water temperature rises into the temperature limit range, the consequence is a limitation of the retarder braking torque to protect the vehicle cooling system. If the temperature rises above the temperature limit range, there is no more braking torque output. While the temperature limit is effective or if there is a retarder failure, the service brake must be used to control the vehicle. The control unit (2) also cuts back braking torque if oil temperature rises too rapidly, irrespective of actual oil temperature.

2.2

Function and Control System (Continue)

Casing ventilation (23) During braking, the oil displaces the air present in the working circuit via the casing ventilation (23) and the ventilation system (22) out of the retarder. Once the working circuit is free of air, a float rises and closes the casing ventilation. Stator pins (45) When the working chamber is empty, the rotor (46) sets up in it an air flow, which is retarded by the stator (44). To minimize this loss, automatically operating stator pins have been installed in the outer zone of the stator blades. The pin plates steer the accelerated airflow past the stator blades and prevent the build-up of an effective flow. When the working chamber is full of oil, the oil presses the plates back on their seats against the force of the spring and the full space between the blades is available. Check valve (66) stainless-steel heat exchanger The check valve (66) prevents the airflow emptying the heat exchanger insert of oil when idling.
