Abstract

A transfer case gear control system comprises an air source, an electromagnetic valve, a transfer case gear shift air cylinder and a neutral gear control valve, wherein the air source, the electromagnetic valve and the transfer case gear shift air cylinder are in communication control; the neutral gear control valve communicates with the air source; the neutral gear control valve is provided witha gear air inlet, a control valve neutral gear outlet and a control valve gear outlet; the electromagnetic valve is provided with a high gear air ventilation outlet, a low gear air ventilation outletand an electromagnetic valve air inlet, the high gear air ventilation outlet and the low gear air ventilation outlet are connected with a high gear inlet and a low gear inlet of the transfer case gearshift air cylinder respectively; and the electromagnetic valve air inlet communicates with the control valve gear outlet; and gear electrical signals comprise a low gear electrical signal and a highgear electrical signal, the neutral gear control valve shifts the control valve gear outlet and the control valve neutral gear outlet through neutral gear control signals, gear protection is realized,off-gear occurrence is avoided, and neutral gear protection is achieved.

Description

technical field [0001] The invention relates to a shift gear control system. Background technique [0002] On a multi-axis drive vehicle, in order to distribute the power output by the transmission to each drive axle, a transfer case is generally installed. The basic structure of the transfer case is also a gear transmission system, and its input shaft and the output shaft of the transmission pass through a universal joint. The transmission device is connected, and its output shaft is divided into front and rear output shafts, the front output shaft is connected with the front drive shaft through the universal transmission device, and the rear output shaft is connected with the rear drive shaft through the universal joint transmission device. [0003] In order to adapt to a variety of complex road conditions, off-road vehicles generally have two gears, and some vehicles that require power take-off equipment also need the transfer case to be set in neutral. The structure of ...
