Braking System

In order to adapt to the development of the medium and heavy truck market and meet the auxiliary braking needs of the entire vehicle in terms of safe driving, DARE AUTO began to establish a hydraulic retarder product research and development team in the North American R&D Center in 2012 and collect relevant product research and development data. The...

Hydraulic retarder The hydraulic retarder is a hydraulic device that reduces the traveling speed of a vehicle. It is generally composed of the retarder body, control device, electronic control unit, and other components. In the retarder body structure, the rotor and stator jointly constitute a working chamber. When the hydraulic retarder is operating, the...

Hydraulic retarder braking The stator is integrated with the retarder housing and connected to the rear end or frame of the transmission. The rotor is connected to the transmission shaft through a hollow shaft, and blades are cast on both the rotor and stator. During operation, pressure is applied to the oil pool through the operation of the control valve...

Hydraulic retarder The automobile retarder energizes the excitation coil of the stator assembly through a control circuit to generate a magnetic field. The rotor assembly rotates at high speed with the vehicle transmission part, cutting magnetic lines of force, generating reverse torque, and slowing the vehicle. According to their different working...

Advantages of hydraulic retarders The retarding efficiency is higher than that of the engine retarding device, and it can drive downhill at relatively high speeds; Small size and mass, can be integrated with the transmission; No wear occurs during operation; The heat generated by the working fluid is easily transmitted and dissipated, and can maintain the...
