The invention belongs to the technical field of vehicle electric driving, and particularly relates to a compact electric driving system gear shifting mechanism which comprises a voice coil motor, a motor mounting plate, a connecting swing rod, a self-locking mechanism, a grating reading head, a grating ruler, a U-shaped groove and a self-locking pin. The executing mechanism comprises a rotating shaft, a shifting fork, a sliding block, a left side combination gear sleeve, a right side combination gear sleeve, a middle hub and a combination sleeve. According to the working principle, the actuating mechanism forms a swing angle, the synchronizer is driven to work by connecting the swing rod and the rotating shaft, and a first gear, a neutral gear and a second gear can be achieved. Specifically, a voice coil motor pushes a motor mounting plate, the motor mounting plate is rotationally connected with a swing rod, the swing rod is connected with a rotating shaft to be fixed, and the rotating shaft is driven to rotate; the rotating shaft rotates to drive a shifting fork to swing left and right; and the synchronizer combination sleeve is connected with the left side combination gear sleeve and the right side combination gear sleeve by moving left and right, so that the gear engaging operation of a low gear, a high gear and a neutral gear is realized.
本发明属于车辆电驱动技术领域,具体涉及一种紧凑型电驱动系统换挡机构,其作动机构包括音圈电机、电机安装板、连接摆杆、自锁机构、光栅读头、光栅尺、U型槽、自锁销。执行机构包含转轴、拨叉、滑块、左侧结合齿套、右侧结合齿套、中间毂和结合套。其工作原理为作动机构形成摆动角度,通过连接摆杆和转轴,带动同步器工作,可实现挡位一、空挡、挡位二三个位置。具体如下:音圈电机推动电机安装板,电机安装板转动连接摆杆,连接摆杆与转轴固定,带动转轴转动,转轴的转动带动拨叉做左右摆动,此时拨叉上的滑块推动同步器的接合套,使其左右移动完成同步器结合套与左侧结合齿套和右侧结合齿套的连接,从而实现低挡、高挡和空挡的挂挡操作。
