An integrated electrically controlled hydraulic commercial vehicle automatic transmission retarder

The present invention discloses an integrated electronically controlled hydrodynamic retarder commercial vehicle automatic transmission, comprising a transmission housing, the transmission housing includes a front portion and a rear portion; a torque converter comprising a power input means; transmit power to the at least one set of planetary gear train; hydraulic automatic transmission in order to achieve at least a set of rotating clutches and brake clutch shift; order to control and perform the braking function and the shift quality auxiliary hydraulic valve and solenoid valve; a control signal to provide a set of at least the electronic control unit collects various sensor signals; at least one set of test status parameters of the hydraulic automatic transmission sensors, the auxiliary braking device at the rear of the hydraulic automatic transmission installed retarder. Hydraulic automatic transmission using a high-performance controller and hydraulic system to achieve real-time retarder, with reasonable match work reliably reduce transmission costs, improve driving safety of the vehicle.
