Buffer type continuously variable transmission

Abstract

The invention provides a buffer type continuously variable transmission. The buffer type continuously variable transmission comprises a shell, wherein a continuously variable transmission structure is installed in the shell; a driving structure is installed outside the shell; the continuously variable transmission structure and the driving structure are connected through a buffer structure; the buffer structure comprises a connecting shaft, a connector, a connecting cover, a cylindrical slot, a cylindrical insertion block, positioning slots, a stop block, buffer slots, a buffer block and a buffer spring; the connector is installed outside the shell and connected with the continuously variable transmission structure; the connecting shaft is connected with the driving structure; the cylindrical slot is formed in the connector; the cylindrical insertion block is inserted into the cylindrical slot and fixedly connected with the end of the connecting shaft; and the positioning slots and the buffer slots are formed in the inner wall of the cylindrical slot and communicated with one another. According to the buffer type continuously variable transmission provided by the invention, the instantaneous torsion generated by driving equipment is slowed down, the safety of the transmission and the driving equipment is protected, and the service life of the transmission and the driving equipment is remarkably prolonged.

Description

technical field [0001] The present application relates to the technical field of transmissions, in particular to a buffer type continuously variable transmission. Background technique [0002] At present, the transmission is a mechanism used to change the speed and torque from the engine. It can fix or step by step to change the transmission ratio of the output shaft and the input shaft, also known as the gearbox. Speed ​​changer is made up of speed change transmission mechanism and operating mechanism, and some automobiles also have power output mechanism. Transmissions are mainly used in automobiles, but there are also applications for transmissions in other areas. Transmissions can be divided into three categories: stepped transmissions, continuously variable transmissions and integrated transmissions. Continuously variable transmission adopts the transmission belt and the driving and driven wheels with variable working diameter to transmit power, which can realize the ...

AI Technical Summary

Problems solved by technology

[0003] When a continuously variable transmission is used, it is usually driven by a driving device, mainly driven by a driving motor. The driving motor is connected to the drive shaft of the continuously variable transmission through a coupling. Because of the rigid connection, when the driving motor is running , the torque generated instantly is large, which will cause damage to the drive shaft of the continuously variable transmission and the drive motor itself, and the damage will be greater after repeated use, which will reduce the service life of the drive motor of the continuously variable transmission
