The invention discloses an automobile transmission shaft with a kinetic energy recovery function, and relates to the technical field of vehicle transmission. The problem of torque transmission vibration energy recovery is solved. The driving shaft is in transmission connection with a vehicle driving source, the driven shaft is in transmission connection with a vehicle driving wheel, the transition shaft is used for being in transmission connection with the driving shaft and the driven shaft, and the energy recovery part is fixed to a vehicle body. The opposite sides of the driving shaft and the transition shaft are each provided with a set of pawls. The driving shaft and the transition shaft are arranged, the driving shaft and the transition shaft are meshed and matched through the pawls, meanwhile, energy conversion is conducted through piezoelectric ceramics, so that second-order vibration energy in the forklift driving or forklift driving process can be absorbed and converted, energy recovery is achieved, meanwhile, a rubber cushion block is arranged, on one hand, vibration buffering can be conducted to a certain degree, and on the other hand, the energy recovery efficiency is improved. And on the other hand, the piezoelectric ceramics can be prevented from being damaged when being driven by a relatively large torque.

    本发明公开了一种具备动能回收的汽车传动轴,涉及车辆传动技术领域;为了解决扭矩传递震动能量回收问题;具体包括与车辆驱动源传动连接的驱动轴、与车辆驱动轮传动连接的从动轴、用于传动连接驱动轴与从动轴的过渡轴以及固定于车身的能量回收部,所述驱动轴通过限位凸轴活动插接于过渡轴的内壁,且所述驱动轴与过渡轴的相对一侧分别设置有一组棘爪。本发明通过设置驱动轴与过渡轴,利用棘爪将驱动轴与过渡轴咬合配合,且同时利用压电陶瓷进行能量转化,从而能驱动或叉车过程中的二阶震动能量进行吸收转化,实现能量回收,同时设置橡胶垫块,其一方面能进行一定程度的震动缓冲,另一方面也能防止压电陶瓷受到较大的扭矩驱动时受损。
