What is the principle of hydraulic retarder braking?
1 Answers
The principle of hydraulic retarder braking is to use liquid damping to produce a retarding effect, which can be installed in front of or behind the transmission. When a vehicle is going downhill, the exhaust brake provides good braking performance. However, for large trucks with heavy tonnage, the effectiveness of the exhaust brake is limited, and it may also damage the engine. Advantages of hydraulic retarders: they can be integrated with the transmission, have smaller size and mass, experience less wear during operation, dissipate heat effectively, and prevent wheel slippage during braking on slippery roads. Disadvantages: they take longer to engage and disengage, and there is some power loss when not in operation.
