Wheel-side reducer with brake for bracket carrier

Abstract

The invention relates to a wheel-side reducer with a brake for a bracket carrier which mainly comprises the brake, a double-planet reducer, a brake shell body, a brake shell, an inner bracket, a braking spring, a friction plate, a bearing, a spline shaft sleeve, a stop block, a distance sleeve, a round nut, an internal annular gear, an end cover gear ring, planet gears, a sun gear, an air permeable cap, an oil drain plug, an oil filling hole and a fixing block. An output end of a travelling mechanism adopts a brake plus reducer integrated design, the brake adopts totally closed wet-type braking, a spring ring comprises 30 small springs, the ring friction plate comprises 8 static friction plates and 9 dynamic friction plates, integral braking and hydraulic releasing are carried out, the spline shaft sleeve and the double-planet reducer are connected, the reduction is realized by a first-grade planet gear and a second-grade planet gear, the transmission speed ratio is 40 to 1, and the reducer and a travelling wheel are connected, thus driving the whole vehicle to run. The device has advanced design, compact structure, small volume, good heat dissipation, steady running and safe and reliable properties.

Description

technical field [0001] The invention relates to a wheel-side speed reducer with a brake for a support carrier, and belongs to the technical field of design and manufacture of auxiliary transportation equipment parts in coal mines. Background technique [0002] Auxiliary transportation equipment used in coal mines—support trucks are specially used to transport and transport support supports. Since the support supports are specially used to support coal mining roadways, most of them are heavy and require a large bearing capacity. Due to the underground environment of coal mines The ground is harsh and the ground undulates greatly. The support truck must have better braking and deceleration devices to ensure the safety of transportation. [0003] In the existing equipment, braking and deceleration are mostly set separately, and most of them are braking at the input end, resulting in functional disconnection and incoordination, which causes great difficulties in the use and oper...

Problems solved by technology

[0003] In the existing equipment, most of the braking and deceleration are set separately, and most of them are braking at the input end, resulting in functional disconnection and incoordination, which causes great difficulties to the use and operation of the support vehicle.
