Description

Technical Field

[0001] The utility model relates to a ventilation pipe structure of an automobile gearbox. Background Art

[0002] The vent plug assembly is commonly used in the gearbox, which is directly pressed or threaded on the gearbox housing, and the vent cap is relatively low. When the vehicle is driving in the rain, the tires will bring up water mist. When wading, the water will impact the gearbox, and the water surface will cover the vent plug assembly and enter the gearbox, causing the gearbox oil to emulsify. The gears, bearings, oil seals and other parts inside the gearbox will fail due to abnormal wear due to insufficient oil film. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a gearbox U-shaped ventilation pipe assembly, which increases the pipe height and bends the pipe assembly into an inverted U shape, thereby effectively avoiding muddy water from entering the gearbox and preventing the gearbox from failing.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A gearbox U-shaped vent pipe assembly includes a vent plug, which is connected to a gearbox housing. A vent pipe is connected to the vent plug. The vent pipe has a U-shaped elbow at one end away from the vent plug, and the opening of the U-shaped elbow faces the side where the vent plug is located. The U-shaped elbow has two ends that are connected to each other, one of which is connected to the vent pipe, and the other end is provided with a vent cap.

[0006] An elastic clamp is arranged at the upper end of the vent plug, and the vent plug is connected to the vent pipe through the elastic clamp.

[0007] The lower end of the vent plug is also provided with an elastic clamp, through which the vent plug is connected to the gearbox housing.

[0008] The U-shaped elbow is provided with a wire clip, through which the entire vent pipe assembly is fixed on the gearbox bracket.

[0009] The U-shaped elbow is integrally formed with the vent pipe or connected with the vent pipe via an elastic clamp.

[0010] The vent pipe consists of two sections, an upper section and a lower section, and the angle between the two sections is an obtuse angle.

[0011] The ventilation pipe is a plastic pipe.

[0012] The vent cap is press-fitted onto the end of the U-shaped elbow.

[0013] The vent cap and the end of the U-shaped elbow are connected by interference fit.

[0014] The vent plug is a rubber hose.

[0015] The beneficial effects of the utility model are:

[0016] The U-shaped vent pipe assembly of the utility model increases the pipe height and bends the pipe assembly into an inverted U shape, which can effectively prevent muddy water from entering the interior of the gearbox and prevent the gearbox from failing. BRIEF DESCRIPTION OF THE DRAWINGS
