The invention discloses a dual-motor power synthesis device for electric vehicle driving, and particularly relates to the technical field of electric vehicle transmission; the dual-motor power synthesis device comprises a front rod and front wheels, and two sides of the front rod are fixedly connected with two groups of front wheels. By arranging a caterpillar band, a first bearing, a first gear,variable-speed motors and a third gear, when the device is started, the variable-speed motors, the first gear and the third gear are used for driving the front wheels and rear wheels to roll, and whenspeed changing is needed, only the two sets of variable-speed motors need to be controlled to synchronously change the speed to a certain numerical value, and when speed changing and steering of a vehicle can be achieved, the steering function is achieved only by changing the variable-speed motors to generate different speeds and utilizing different speed differences on the two sides, the steering requirement can be met only by starting the variable-speed motor on the other side without starting the variable-speed motor on one side, the whole process can be completed only by controlling the motors, operation is simple and easy, and practicability is high. The problem that an existing double-motor synthesis device is inconvenient to change speed and steer is solved.
本发明公开了一种用于电动车辆驱动的双电机动力合成装置,具体涉及电动车辆传动技术领域,包括前杆和前轮,所述前杆的两侧固定连接有两组前轮。本发明通过设置有履带、第一轴承、第一齿轮、变速电机和第三齿轮,装置在启动时,利用变速电机、第一齿轮和第三齿轮来驱动前轮和后轮的滚动,需要变速时,只需要控制两组变速电机同步变速到一定的数值,可以实现车辆的变速,转向的时候,只需要利用改变变速电机产生不同速度,利用两边不同的速度差来做到转向的功能,也可以一边的变速电机不启动,只启动另一边的变速电机也可实现转向的需求,全程只需要对电机进行控制即可完成,简单易操作,解决了现有双电机合成装置变速和转向不便的问题。
