Automatic gearbox universal integrated air passage arrangement structure and application method thereof

Abstract

The invention provides an automatic gearbox universal integrated air passage arrangement structure and an application method thereof, and belongs to the technical field of automobile manufacturing. The automatic gearbox universal integrated air passage arrangement structure comprises a first air passage reserved structure, a second air passage reserved structure, a third air passage reserved structure, a fourth air passage reserved structure and a plurality of process holes for air passage processing, One end of the first air passage reserved structure and one end of the second air passage reserved structure face the peripheral face of a gearbox front shell, and the other ends are located at a first installation position. One end of the fourth air passage reserved structure is located on the inner side face of the gearbox front shell, and the other end of the fourth air passage reserved structure is located on the outer side face of the gearbox front shell except the first installation position. The structure has the beneficial effects that through the integrated general design of a clutch actuator and a brake air inlet channel, the installation matching requirements of different types (different manufacturers) of clutch actuators and brakes can be met, the interference risk of air channels in the gearbox front shell is reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The present application relates to the technical field of automobile manufacturing, in particular to an automatic transmission (Auto Transmission, AMT) generalized integrated airway layout structure and an application method thereof. Background technique [0002] With the development of domestic commercial vehicle transmissions, the comfort and simplicity of operation are more and more valued by the market, so AMT transmissions have been well developed. The AMT gearbox is improved on the basis of the traditional manual gear transmission; it is an electromechanical-hydraulic integrated automatic transmission that combines the advantages of AT and MT; AMT not only has the advantages of automatic transmission of ordinary automatic transmissions, but also retains The original manual transmission gear transmission has the advantages of high efficiency, low cost, simple structure and easy manufacture. Under the condition that the overall transmission struct...

AI Technical Summary

Problems solved by technology

[0006] (1) The installation and layout of the intake duct of the clutch actuator and the intake duct of the brake are fixed. When matching clutch actuators and brakes of different models (or different manufacturers), it is difficult to adjust the structure of the intake duct, and the overall intake duct needs to be redesigned. or adjust the structural design of the front case of the gearbox, the design change is complex and costly

[0007] (2) The space in the inner cavity of the gearbox front case is narrow, and the arrangement of the air pipe inside the cavity is difficult, and there is a risk of interference in the arrangement, which increases the manufacturing cost of the special intake pipe assembly.
