Description

technical field

[0001] The invention relates to the technical field of hydraulic machinery, in particular to a hydraulic deceleration device installed between a vehicle gearbox and a vehicle drive axle. Background technique

[0002] For vehicles with high speed and heavy loads, and vehicles requiring short braking distance and quick response, traditional mechanical friction brakes alone cannot meet people's requirements for vehicle safety, and hydraulic retarders can safely and reliably assist vehicle braking. To make the vehicle meet the safety requirements, therefore, it is widely used in vehicles.

[0003] The hydraulic reducer is a device that converts mechanical energy into liquid heat energy and has low wear and tear. It is composed of a rotor impeller, a stator impeller, and a rapid liquid filling and discharging mechanism. A working chamber is formed between the rotor impeller and the stator impeller. When working, the rotor impeller is driven by the transmission sy...
