Description

Technical Field

[0001] The utility model belongs to the field of transmission auxiliary devices, in particular to a transmission single H valve connecting device. Background Art

[0002] At present, when medium and heavy-duty vehicle transmissions are shifting between high and low gears, a pneumatic single H valve is required to control the internal structure of the transmission for conversion. The pneumatic single H valve is installed on the transmission cover using a valve support, and two bolts are used to limit and fix the valve support to prevent the pneumatic single H valve from repeatedly swinging and pulling the air pipe after the vehicle vibrates, causing air leakage in the air pipe, and then causing gear shift failure and other faults. At the same time, the transmission control device assembly will be placed above the valve support after installation.

[0003] However, the clearance between the mounting bolts of the control housing and the valve support is very small. When the valve support needs to be removed, the control device assembly must be removed first before the valve support can be removed. When the blank of the control device housing is large, there may even be interference between the mounting bolts of the control housing and the valve support. Utility Model Content

[0004] The utility model provides a transmission single H valve connecting device, which solves the problem that when the valve support needs to be disassembled, the operating device assembly must be disassembled first before the valve support can be disassembled.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A transmission single H valve connection device comprises an upper cover (1), a valve support (3) being fixed on the upper cover (1), the valve support (3) being in close contact with a side surface of the upper cover (1), a pneumatic single H valve (6) being connected to the valve support (3), and a control assembly (2) being connected to the pneumatic single H valve (6).

[0007] Preferably, the valve support (3) is fixed to the upper cover (1) by means of bolts A (4).

[0008] Preferably, the valve support (3) comprises an upper cover connecting portion (7) and a pneumatic single H valve connecting portion (8).

[0009] Preferably, the upper cover connection portion (7) and the pneumatic single H valve connection portion (8) are integrally formed.

[0010] Preferably, the upper cover connecting portion (7) comprises two vertically arranged metal sheets, and the ends of the two metal sheets are integrally formed.

[0011] Preferably, a portion of the metal sheet is provided with bolt holes and is fixed to the top of the upper cover, and another portion of the metal sheet is provided on the side surface of the upper cover.

[0012] Preferably, the thickness of the metal sheet disposed on the side surface of the upper cover is greater than the thickness of the metal sheet disposed on the top of the upper cover.

[0013] Preferably, a hole is provided on the pneumatic single H valve connecting portion (8) for fixing the pneumatic single H valve (6).

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a transmission single H-valve connection device, which, under the premise of ensuring that the valve support is fixed on the upper cover, the valve support is also tightly attached to the side surface of the upper cover, the vertical surface of the valve support is increased, and the bolt B on the valve support is removed for installation. The vertical surface of the valve support is tightly attached to the side surface of the upper cover for rotation limitation. During installation, the valve support is fixed to the upper surface of the upper cover, and the valve support is also tightly attached to the side surface of the upper cover. When the valve support needs to be disassembled, the operating assembly and unnecessary bolts will not be disassembled. The overall structure is simple, does not affect the original fixing method, and ensures the rotation limitation of the valve support.

[0015] Furthermore, the thickness of the metal sheet arranged on the side surface of the upper cover is greater than the thickness of the metal sheet arranged on the top of the upper cover, thereby ensuring the stability of the valve support. BRIEF DESCRIPTION OF THE DRAWINGS
