Problems solved by technology

[0002]The usual electric vehicle motor transmission mechanism is not equipped with a buffer mechanism, so the gears are rigidly combined when shifting gears, resulting in large impact and loud noise, which makes the rider feel uncomfortable. Comfortable, and the transmission mechanism is easily damaged

Embodiment 1

[0014] like Figure 1 to Figure 4 As shown, the two-way buffer transmission gear includes a main shaft 6, and an input tooth 45 is set on the main shaft 6. The input tooth 45 and the main shaft 6 are respectively provided with a groove 36, and a damping spring 38 is installed in the groove 36, and the shock absorption The upper part of the spring 38 is fixed on the input tooth 45, and the lower part of the damping spring 38 is supported on the main shaft 6. When the input tooth 45 rotates, the upper part of the main damping spring 38 is stuck, and the lower part of the damping spring 38 is stuck on the main shaft 6. On the other hand, the input tooth 45 can rotate on the main shaft 6 to a limited extent.

[0015] After the motor 3 is energized and rotated, the motor shaft gear 47 rotates to drive the input gear 45 to rotate, and the input gear 45 will first rotate the main shaft 6 by a certain angle, so that the damping spring 38 in the groove 36 is compressed, and then driven...

Abstract

The invention belongs to the technical field of electric vehicle power transmission and solves the problem of impact caused by rigid combination during gear shifting in the prior art. A two-way buffering transmission gear comprises a motor, the motor is connected with a box, a motor shaft, a main shaft and an output shaft are arranged inside the box, and a transmission gear is arranged on the motor shaft, the main shaft and the output shaft respectively. The two-way buffering transmission gear is characterized in that the input gear of the main shaft and the main shaft are provided with grooves respectively, damping springs are arranged in the grooves, part of every damping spring abuts against the input gear, part of every spring abuts against the main shaft, and power of the motor is transmitted to the output shaft after being damped and cushioned by the above mechanisms.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power transmission. Background technique [0002] The usual electric vehicle motor transmission mechanism is not provided with a buffer mechanism, so that the gears are rigidly combined when shifting gears, resulting in large impact and high noise, which makes the rider feel uncomfortable, and the transmission mechanism is easily damaged. Contents of the invention [0003] In order to solve the above disadvantages, the purpose of the present invention is to provide a simple structure, small size, flexible power output when shifting gears, no impact feeling, more comfortable for the driver, and more durable gear engagement. [0004] In order to realize the purpose of the present invention, the first technical scheme of the present invention is: a kind of two-way buffer transmission gear, comprises motor, and motor is connected with casing, is provided with motor shaft, main shaft, and ou...
