[0002] The drive axle is a mechanism located at the end of the transmission system that can change the speed and torque from the transmission and transmit them to the drive wheels. It is generally composed of a final reducer, a differential, a wheel transmission device and a drive axle housing.

[0003] As an important component of an electric forklift, the drive axle can improve the stability of the electric forklift during use. After searching, the patent application number 202220608665.0 discloses a highly stable electric forklift drive axle. By providing a shock-absorbing mechanism between the second half-axle sleeve and the drive axle housing, the drive axle can timely buffer the force acting on the forklift drive axle, thereby improving the stability of the forklift drive axle. In addition, the drive axle protective housing is provided with heat dissipation holes for heat dissipation. In actual use, this patent may have the following problems:

[0004] First, the use of simple heat dissipation holes for heat dissipation has relatively low heat dissipation efficiency and poor heat dissipation effect. In addition, during the driving process of the electric forklift, the heat dissipation holes on the drive axle are easily blocked by dust impurities or some pollutants on the ground, which seriously affects the normal heat dissipation of the drive axle.

[0005] Secondly, traditional drive axles are usually installed at fixed angles, lack flexibility, cannot adapt well to complex and changing working environments, and cannot meet diverse operating requirements. Utility Model Content

One side of the heat dissipation shell is provided with evenly distributed heat dissipation holes. A self-cleaning heat dissipation component is provided in the heat dissipation shell, and an angle adjustment component is connected to the connecting end.

[0008] The self-cleaning heat dissipation assembly includes a triangular bracket fixedly connected to the heat dissipation housing, a dual-axis motor fixedly mounted on the side wall of the triangular bracket, a heat exhaust fan fixedly sleeved on the first output shaft of the dual-axis motor, and a cleaning brush fixedly sleeved on the second output shaft of the dual-axis motor;

[0009] The angle adjustment assembly includes a mounting seat, an adjustment shaft, a worm gear fixedly sleeved on the adjustment shaft, two support seats symmetrically fixed to the side walls of the mounting seat, a transmission shaft and a worm fixedly sleeved on the transmission shaft.

[0016] The beneficial effects of the utility model are:

[0017] 1. A self-cleaning heat dissipation component is provided.
