[0002] The function of the automobile hydraulic retarder is to enable the retarder when the automobile is decelerating or going down a long slope, so that the vehicle can decelerate smoothly and avoid the wear and heat of the brake components caused by the use of brakes. The hydraulic retarder is a device that uses liquid damping to produce a retarding effect, thereby decelerating the vehicle. Installing a hydraulic retarder in the transmission system of a truck has become an urgent need for truck manufacturers and users. The current hydraulic retarder is generally installed at the rear end of the transmission housing, but the commonly used automobile transmission housing does not have a reserved installation connection device for the hydraulic retarder. In order to install the retarder in the automobile transmission system to achieve the purpose of slow braking, a transmission box can be installed between the front and rear drive shafts, and then the retarder is installed on the transmission box. The speed of the retarder main shaft is increased by a set of gear transmission mechanisms, so that the diameter of the retarder turbine and the size and mass of the entire retarder can be greatly reduced.
