Technical Field

[0002] The gearbox mainly refers to the car's gearbox, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and produces speed and torque changes through different gear combinations; while the automatic gearbox AT is composed of a torque converter, planetary gears and a hydraulic control system, and achieves speed and torque changes through hydraulic transmission and gear combinations.

The structure of the application is reasonable. By running the oil pump, the oil in the chassis enters the arc-shaped cavity group through the oil inlet pipe and then is discharged into the chassis through the oil outlet pipe, so as to achieve the effect of circulating the oil, and the surface can avoid the deposition of wear debris. By passing the oil through the arc-shaped cavity in sequence and the arc-shaped cavity is located in the heat sink, it is conducive to dissipating the heat in the oil and achieving the effect of heat dissipation. By installing an arc-shaped filter sheet in the arc-shaped cavity and distributing and installing multiple round magnet sheets on the arc-shaped filter sheet, it is conducive to filtering and adsorbing metal debris in the oil. At the same time, opening the arc-shaped cover, the arc-shaped filter sheet can be taken out for cleaning, reducing the degree of accelerated wear due to metal debris.
