Continuously variable speed drive device for electric motorcycle

Abstract

The invention discloses a continuously variable speed driving device for an electric motorcycle. The device is composed of a driving wheel mechanism, a driven wheel mechanism and a driving belt. The driving wheel mechanism consists of a driving shaft, a shaft sleeve, a driving pulley, a movable pulley, pulley beads and an abutting plate. The driving belt is a V-shaped belt with top and bottom teeth. The driving belt consists of a driving belt body. A reinforcing layer is arranged outside the driving belt body. A plurality of evenly distributed heat dissipation grooves are arranged outside thedriving belt body and in the two side end faces of the reinforcing layer. A heat dissipation convex part is formed between each two adjacent heat dissipation grooves. Moreover, a plurality of evenly distributed reinforcing parts are arranged outside the driving belt body and on the outer edge of the reinforcing layer.

Description

Technical field [0001] The invention belongs to the technical field of electric motorcycles, relates to an electric motorcycle drive device, and particularly refers to a continuously variable speed drive device for an electric motorcycle. Background technique [0002] Under the global trend of environmental protection and green energy, the promotion and popularization of electric motorcycles is unstoppable. However, one of the existing driving methods of electric motorcycles is to directly replace the rear wheels with in-wheel motors. However, the motors have to withstand the impact of the road and start the motors. The torque is not easy to control, and the high-speed performance is difficult to overcome; the other is to directly drive the rear wheel after deceleration by the mid-mounted motor, but this design must increase the motor power to overcome the insufficient torque at high speeds for high-speed performance. The problem of increased power consumption and insufficient en...

Problems solved by technology

[0002] Under the global trend of environmental protection and green energy, the promotion and popularization of electric motorcycles is unstoppable. However, one of the existing driving methods of electric motorcycles is to directly replace the rear wheels with hub motors. However, the motor must withstand the impact force of the road. The torque is not easy to control, and the high-speed performance is difficult to overcome; the other is to directly drive the rear wheels after the mid-mounted motor is decelerated. However, in order to achieve high-speed performance, the power of the motor must be increased to overcome the lack of torque at high speeds. The problem of increased power consumption and insufficient battery life of electric motorcycles, etc. must be increased to solve this problem, and the resulting increase in cost has become another obstacle to the promotion of electric motorcycles
