Abstract

A transmission circuit control shift cylinder control system, including a plug-in auxiliary box shift cylinder, a segmented auxiliary box shift cylinder, the plug-in auxiliary box shift cylinder passes through a low gear solenoid valve, a high gear solenoid valve, and an air storage cylinder Connection, the segmented auxiliary box shift cylinder is connected with the air storage cylinder after another set of low gear solenoid valves and high gear solenoid valves; a stepped journal is provided at the shift shaft end of the segmented auxiliary box, and the stepped journal A travel switch is provided, and the travel switch is electrically connected with the control unit; a stepped journal is provided at the shift shaft end of the plug-in auxiliary box, and a high-speed travel switch and a low-speed travel switch are arranged at the stepped journal; There is a clutch switch, and a plug-in high and low gear preselection switch is arranged in the gear change handle ball. After the clutch switch and the plug-in high and low gear preselection switch are connected in series, they are electrically connected to the low gear solenoid valve and high gear solenoid valve of the plug-in auxiliary box; the power supply is provided by On-board battery provided.

Description

technical field [0001] The invention belongs to a control system of a shifting cylinder of a mechanical multi-speed transmission. Background technique [0002] As we all know, the existing mechanical multi-speed transmission is composed of a plug-in auxiliary box, a main box and a segmented auxiliary box. The plug-in auxiliary box is placed in front of the main box and integrated with the main box; Behind the main gearbox. The high and low gear switching of the plug-in auxiliary box and the high-grade and low-gear switching of the segmented auxiliary box are all controlled by mechanical stroke valves. There are different degrees of failures when switching between the low-half gear and the high-end and low-gear areas of the segmented sub-box. Contents of the invention [0003] In order to solve the problem of many air leakage points in the control system of the shift cylinder of a mechanical multi-speed transmission, the invention proposes a control system in which the tr...
