Abstract | The utility model discloses a hydraulic control reducer having a neutral gear and used for electric vehicle driving motors, which belongs to power transmission systems of electric vehicles. A reducer and a motor are integrated. A motor shaft and a reducer input shaft are connected with each other at the front end of the motor. A driving pinion on the reducer input shaft is slidably connected with the reducer input shaft. A meshing sleeve is fixed to the shaft end of the reducer input shaft. The driving pinion is meshed with the meshing sleeve, and is further connected with a piston through a shift fork. The driving pinion, after being shifted by the shift fork, is meshed or disengaged with a transmission gear on output of a reducer output shaft. When a vehicle runs rapidly under non-traction conditions, the vehicle is in a two-wheel-drive state, at this moment a front axle is at a high-speed gear position, a rear axle is disengaged, and damage is possibly done to the motor if the rear axle has no disengaging |
