Embodiment Construction

[0023] Taking a main and auxiliary case transmission with a shift booster, without an auxiliary case intermediate shaft power take-off, and with three main case shift fork shafts as an example, the air circuit control mechanism of the present invention will be further described.

[0024] Such as Figure 1-2 As shown, the air circuit control mechanism for the main and auxiliary tanks provided by the present invention includes an air circuit control board 2 , an air circuit control valve 6 and a return spring 5 .

[0025] One end of the gas circuit control board 2 is a trigger rod, which contacts with the valve stem of the gas circuit control valve 6 , and the return spring 5 is pressed between the gas circuit control valve 6 and the gas circuit control board 2 .

[0026] Such as image 3 As shown, three first lockout windows 12 and one second lockout window 13 are provided on the main body panel of the air circuit control panel 2; One-to-one correspondence, the rear ends of t...

Abstract

In order to solve the problems of the existing main and auxiliary box structure transmission, the air circuit control mechanism has complicated air circuit connection, many fault points, troublesome maintenance and detection, and the main box may grab gear during the switching process of the auxiliary box, the present invention provides a main and auxiliary box The air circuit control mechanism of the box structure transmission includes the air circuit control board, the air circuit control valve and the return spring; the return spring is pressed between the air circuit control valve and the air circuit control board; A first lock window and a second lock window; also include the first and second opening slots arranged on the main and auxiliary case shift fork shafts; through the first opening slot and the first lock window, the second opening The slot cooperates with the second locking window to realize the locking of the main box during the switching process of the auxiliary box, and the unlocking of the main box after the auxiliary box is shifted. The invention avoids the blocking of the main box, and the gas path connection is simple.

Description

technical field [0001] The invention relates to an air circuit control mechanism of a transmission with a main and auxiliary case structure, which is suitable for a transmission with a main and auxiliary case structure without a power take-off. Background technique [0002] The high and low gear switching of the main and auxiliary box structure of the transmission and the auxiliary box is generally in the form of air-controlled shifting. In order to reduce the synchronous inertia of the auxiliary box when synchronizing, it is required that the main box must be in neutral and the auxiliary box control air circuit can be used for high and low gears. Switching, so the air circuit control valve is designed to control the air supply of the auxiliary tank shift air circuit. At present, the air circuit control valve is generally designed on the control assembly, and the air circuit needs to be from the pressure regulating valve at the rear end of the transmission to the air circuit...
