Abstract

The invention relates to a power buffer for electric vehicles. The powder buffer comprises a buffer housing, and a power input cavity, a buffer cavity, a power output cavity and a liquid flow drivingcavity are sequentially formed in the buffer housing; a power input mechanism is arranged in the power input cavity, a main oil inlet is formed in the side wall of the power input cavity, and the power input mechanism includes a power input shaft and a power input piston mechanism; multiple pressurizing pipes are disposed on the side wall of the buffer cavity; the power output cavity is connectedto a retracted opening end of the buffer cavity and internally provided with a power output piston mechanism and a power output shaft; a driving impeller is arranged in the liquid flow driving cavity,and an axis of a liquid inlet pipe and an axis of a liquid drain pipe are located in the tangential direction of the driving impeller. A powder buffer body can be connected between a motor output shaft and the power input shaft, the structure utilizes a hydraulic transmission mechanism as an intermediate medium, and buffer is achieved through hydraulic transmission; when a motor is started quickly, driving pressure generated by a hydraulic force can be stored or reduced.

Description

technical field [0001] The invention relates to a power buffer for electric vehicles, which belongs to the field of electric vehicles. Background technique [0002] The main power medium of electric vehicles is the motor, because the torque and steering of the motor can be flexibly controlled, so electric vehicles can directly control different gears of the vehicle without a gearbox in many cases. Compared with gasoline engines, the biggest feature of motors is faster acceleration , the motor can reach the highest torque in an instant; but it is also for this reason that the motor lacks the buffer of the gearbox. If the motor reaches the maximum torque in an instant and the car is at a standstill or at a low speed, it will bring a certain amount of strain to the transmission components inside the car. Distortion, serious Affect the stability of the car and the stability of the transmission components. Although many manufacturers now reduce the impact of the motor on the tran...
