Abstract

The invention relates to a power torque converter for an electric vehicle. The torque converter comprises a buffer outer shell, and a power input cavity, a buffering cavity, a power output cavity anda liquid flow driving cavity are formed in the buffer outer shell in sequence; a power input mechanism is arranged in the power input cavity, and a main oil inlet hole is formed in the side wall of the power input cavity, the power input mechanism comprises a power input shaft and a power input piston mechanism; a plurality of pressurizing pipes are arranged on the side wall of the buffering cavity, the power output cavity is connected to a necking end of the buffering cavity, a power output piston mechanism and a power output shaft are arranged in the power output cavity; and a driving impeller is arranged in the liquid flow driving cavity, the axis of a liquid inlet pipe and the axis of a liquid discharge pipe are located in the tangential direction of the driving impeller. According tothe torque converter, the power torque converter can be connected between a motor output shaft and the power input shaft, a hydraulic transmission mechanism is used as an intermediate medium by the structure, buffering is achieved through the hydraulic transmission, and the driving pressure generated by hydraulic force can be stored or reduced when the motor is started rapidly.

Description

technical field [0001] The invention relates to a power torque converter 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 o...
