Waterproof automobile speed reducer system

Abstract

The invention discloses a waterproof automobile speed reducer system which is characterized in that a three-way valve, an air compressor and a control unit are used for carrying out air conditioning on a speed reducer, so that different flow directions of air are controlled under different working conditions of an automobile; a first exhaust pipeline of the three-way valve is communicated with a vent valve on an automobile speed reducer, a second exhaust pipeline is communicated with the atmosphere, and a third exhaust pipeline is connected with an air compressor; the control unit is connected with the three-way valve and the air compressor through a control circuit and controls different states of the three-way valve and the air compressor. And a first pressure sensor and a second pressure sensor are respectively arranged inside and outside the speed reducer. The problem that water enters the speed reducer from the vent valve and the lip-shaped oil seal due to large water pressure when an automobile passes through a deepwater road section is effectively solved, meanwhile, the problem that water enters the vent valve and the lip-shaped oil seal is solved, and the problems that oil of the speed reducer fails due to emulsification and even the automobile cannot run are solved. And the device has the advantages of reasonable design, simple structure, safety, reliability and the like.

Description

technical field [0001] The invention relates to the field of automobile reducers, in particular to a waterproof automobile reducer system. Background technique [0002] At present, whether it is a traditional fuel vehicle or an electric vehicle, the reducer uses a vent valve for exhaust and pressure relief, and a lip oil seal is used for dynamic sealing between the reducer and the drive shaft. When the car passes through a deep-water section, due to the high water pressure, water will enter the reducer from the vent valve and lip oil seal, which will cause problems such as the emulsification of the reducer oil, and even cause the vehicle to fail to drive. In the prior art, the usual solution is to add corresponding waterproof measures to the lip-shaped oil seal and the breather valve, but the lip-shaped oil seal can only prevent water splashing. When the oil seal is below the waterline, the main lip and The rotating shaft will create a pumping effect which will cause the wa...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a waterproof reducer system, which solves the problem that the existing technology cannot adjust the air of the reducer under different working conditions of the automobile, and avoids the water pressure when the automobile passes through the deep water section. Larger, the problem that water enters the inside of the reducer from the breather valve and lip oil seal
