Abstract

The invention relates to a gear shift device for a motor vehicle, and in particular relates to an electronic control pneumatic gear shift device of a beam transportation vehicle. The gear shift device comprises a manual transmission gear and at least two gear shift rods; at least one end of each gear shift rod is connected with a piston rod of a double-acting air cylinder; the double-acting air cylinder is fixed on an air cylinder frame at the outer part of the manual transmission gear; a front air opening and a rear air opening of each double-acting air cylinder is connected with an air source through a gas pipe and an electromagnetic valve; the electromagnetic valve is connected with a gear shift control circuit; a gear shift handle controls the electromagnetic valve to supply air to the corresponding double-acting air cylinder respectively through the gear shift control circuit, thus the corresponding gear shift rod is driven to move back and forth to finish the gear shift actions. The gear shift device provided by the invention has the advantages of simple structure and reliable actions, and is simple, convenient and visual to operate, remote control gear shift can be realized on an auxiliary car, the phenomenon of fault gear engaging is avoided, and the safe operation of the beam transportation vehicle is ensured.

Description

【Technical field】 [0001] The invention relates to a shifting device for a motor vehicle, more specifically, to an electronically controlled pneumatic shifting device for a beam transporting vehicle. 【Background technique】 [0002] The gears of motor vehicles can generally be divided into automatic gears and manual gears, and low-gear cars generally use manual gears. For motor vehicles in construction machinery, such as forklifts, bulldozers, etc., most of the gears are manually controlled. The driver toggles the reversing spool of the gearbox through the manual transmission joystick to realize the shifting of the vehicle, such as forward I gear, II gear, neutral gear and reverse gear. Because shifting relies on manual operation, the action is frequent, the labor intensity is high, and the driver is relatively hard, which is not conducive to driving safety. [0003] The beam transport vehicle is a heavy-duty transportation equipment used in conjunction with the bridge erect...
