Abstract
The invention provides a control air circuit structure for a transmission. The control air circuit structure for the transmission comprises a t-branch pipe, a first solenoid valve and a second solenoid valve. An air filter of the transmission is connected with the t-branch pipe. Air filtered through the air filter is divided into a low-gear air circuit and a high-gear air circuit through the t-branch pipe. The first solenoid valve is mounted on the low-gear air circuit. The second solenoid valve is mounted on the high-gear air circuit. The two air circuits are controlled through the corresponding solenoid valves to be connected or disconnected. The first solenoid valve is connected with a gear shifting handle through a second wire harness. The second solenoid valve is connected with the gear shifting handle through a first wire harness. When a button of the gear shifting handle is shifted up and down, the low-gear air circuit or the high-gear air circuit is selectively connected, and the transmission is made to be in low-gear region or the high-gear region; and the air circuits are controlled by the adoption of the solenoid valve type parts, the control air circuits of the transmission of a main-auxiliary box structure is simplified greatly, the air circuit arrangement of the transmission is made to be more concise, arrangement of the transmission in a whole vehicle transmission system is facilitated, and meanwhile the fault point possibly generated on the control air circuits of the transmission is reduced to a certain degree.

One tunnel is low-grade gas circuit 10, i.e. enters the low-grade side of auxiliary box cylinder 3, promote piston to low-grade lateral movement, from
And make TR be in low-grade district；Another road is high-grade gas circuit 11, i.e. enters the high-grade side of auxiliary box cylinder,
Promotion piston is to high-grade lateral movement, so that TR is in high-grade district.Mechanical type air valve 5 is by behaviour
Vertical part movement within device 4, thus control it and connect low-grade gas circuit 10 or high-grade gas circuit 11, thus
Realize the low-grade district of speed changer or high-grade district.
Its structure is the most complex, because gas circuit complexity causes speed changer layout in car load transmission system
Will also result in certain difficulty, the trouble point simultaneously caused because of complicated gas circuit is the most more；Therefore, how to optimize
Manipulation gas circuit structure becomes the matter of utmost importance of the speed changer of major-minor case structure.
Summary of the invention
It is an object of the invention to overcome prior art defect, it is provided that a kind of speed changer manipulation gas circuit structure, adopt
Control manipulation gas circuit with electromagnetic type valve parts, simplify the manipulation gas circuit of major-minor case structure speed changer, make change

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail:
As in figure 2 it is shown, the speed changer manipulation gas circuit structure of the present invention, detailed description of the invention is as follows:
Compressed gas from car load gas receiver first passes through the air filter 1 of speed changer 2, the gas after filtration
Body is again through a three-way pipe 14, and being divided into two-way compressed gas, a road is low-grade gas circuit 10, i.e. enters odd-side
The low-grade side of cylinder 3, promotion piston is to low-grade lateral movement, so that TR is in low-grade district；Separately
One tunnel is high-grade gas circuit 11, i.e. enters the high-grade side of auxiliary box cylinder, promote piston to high-grade lateral movement, thus
TR is made to be in high-grade district.This tow channel gas is separately installed with magnetic valve 1 and magnetic valve 29 controls
The break-make of its gas circuit, magnetic valve 1 and magnetic valve 29 pass through wire harness 2 13 and wire harness 1 and change respectively
