Abstract

The invention belongs to the technical field of gearbox parts and operation thereof, and particularly relates to a gear shifting and auxiliary braking device for a planetary gearbox of a coal mine explosion-proof vehicle. The planetary gearbox, an oil pump and a main valve block are integrated, and the planetary gearbox, the oil pump and the main valve block and a gear shifting and unloading device are all arranged in a gearbox body. For a gear shifting part, one end of a gear shifting fixing shaft is fixed in the gearbox, the other end of the gear shifting fixing shaft extends out of the gearbox through a gearbox body side face hole, and the shaft end extending out of the gearbox is connected with a cab control handle through a gear shifting crank and a gear shifting stay wire. For an unloading part, an unloading shifting piece arranged on the gear shifting fixing shaft inside the box body passes through a hole in the bottom of the box body on the same side with an unloading handle through an unloading pull wire to be led out of the box body and is connected to a pedal brake pedal, and therefore the auxiliary braking function of the vehicle is achieved. The gear shifting and auxiliary braking device is compact in arrangement, space-saving and flexible and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of gearbox parts and its operation, in particular to a gear shifting and auxiliary braking device of a planetary gearbox for a coal mine explosion-proof vehicle. Background technique [0002] Modern automotive gearboxes are divided into manual and automatic gearboxes in terms of shifting methods. Automatic gearboxes can automatically shift gears according to the speed of the vehicle, and are suitable for smooth road conditions, long driving distances, and smooth vehicle operation. However, the underground road conditions in coal mines are complex, the road surface is undulating, soft and slippery, and the slope is large, so it is necessary to adjust the gear of the vehicle at any time according to the road conditions to adjust the speed of the vehicle. Increase vehicle dynamics, reduce vehicle fuel consumption and cost. Therefore, the explosion-proof vehicles in coal mines generally adopt manual gearboxes. ...
