Electric control mechanical shift actuator of electric vehicle

Abstract

The invention relates to an electric control mechanical shift actuator of an electric vehicle. The electric control mechanical shift actuator comprises a motor, a shifting fork shaft, a shift shifting fork and a shell. A rotation shaft of the motor penetrates into the shell, the rotation shaft is sleeved with a shift shifting block, and the rotation shaft is fixedly connected with the shift shifting block. A connection shaft is arranged in the shift shifting block. The connection shaft is fixed on the shift shifting block through a fixing part, and a sealing ring is arranged between the shift shifting block and the connection shaft. The end portion of the connection shaft is provided with an angle sensor, and the shift shifting fork is connected under the shift shifting block. The shift shifting fork is provided with the shifting fork shaft, and three grooves are axially formed in the surface of the shifting fork shaft. Locking springs are arranged on the shifting fork shaft in the horizontal and vertical directions, and locking steel balls are arranged at the tail portions of the locking springs. The electric control shift actuator of the electric vehicle has the advantages that the structure is compact, assembly is easy, the sealing ring is arranged between the shift shifting block and the connection shaft, the sealing performance is good, gear shift is performed through direct driving by the motor, the whole occupied space is reduced due to design of two gears, the electric control mechanical shift actuator is provided with a locking device, and the function of preventing falling of gears is achieved.

Description

technical field [0001] The invention relates to an electronically controlled mechanical shift actuator for an electric vehicle. Background technique [0002] In the process of driving, the car must have a shifting mechanism to adapt to various driving conditions. The traditional shifting mechanism mostly uses a manual shifting mechanism. The existing electric automatic shifting mechanism directly drives the gearbox through a motor and has no clutch. In this case The lower gear shifting may not be able to completely eliminate the negative effect of the shifting impact. When shifting, the impact is relatively large, and there are many gears, and most of the structures are more complicated, occupying a large space, and the sealing is not enough. Contents of the invention [0003] The object of the present invention is to provide an electromechanical shift actuator for electric vehicles to overcome the above-mentioned shortcomings in the current prior art. [0004] The purpos...
