Safe Shuttle Wheel Side Brake Reduction System

Abstract

The invention provides a safe shuttle wheel brake deceleration system, which belongs to the technical field of shuttle car brake deceleration system, and includes a wheel brake reducer and a hydraulic system; the wheel brake reducer includes a hub, a first bevel gear , first bevel gear shaft, second bevel gear, second bevel gear shaft, sun gear shaft, sun gear, planetary gear, planetary gear shaft, planet carrier, first shell, second shell, inner ring gear, static friction plate, dynamic friction plate , piston, return screw and return spring. The invention integrates the design of the brake and the wheel-side reducer, and the final stage of braking will not affect the braking effect of the shuttle car if other links other than the final stage are damaged, thereby improving the braking reliability.

Description

technical field [0001] The invention belongs to the technical field of braking and decelerating systems for shuttle cars, and specifically discloses a safe wheel-side braking and decelerating system for shuttle cars. Background technique [0002] The shuttle car is a trackless rubber-tyred vehicle for short-distance rapid transportation in coal mines. As one of the important equipment for short-wall mechanized mining, its main function is to transfer the coal from the continuous miner to the feeder crusher. At present, the deceleration system of the shuttle car mostly adopts a wheel side reducer of the shuttle car provided by the patent number ZL 201010290044.4. However, the above-mentioned deceleration system has the following deficiencies in actual use: [0003] 1) The wheel reducer is directly connected to the tires to drive the shuttle car. The wheel brake is not installed. The brake is installed on the first-stage reducer, which is a high-speed brake. If any link of th...

Problems solved by technology

[0003] 1) The wheel reducer is directly connected to the tires to drive the shuttle car. The wheel brake is not installed. The brake is installed on the first-stage reducer, which is a high-speed brake. If any link of the reducer is damaged, it will directly affect the shuttle. Braking performance of the car, there is a serious safety hazard;

[0004] 2) The spherical seal installation positioning device and dust-proof device are not installed, resulting in insufficient service life of the spherical seal;

[0005] 3) The wheel reducer is responsible for the steering function of the shuttle car, and there is no steering mechanical limit device, which may easily cause interference between the tire steering and the drive shaft;

[0006] 4) There is no mechanical overload protection device, and the overload impact may easily cause serious damage to the reducer
