Safety Wheel Brake Shuttle Traveling System

Abstract

The invention provides a safe type wheel brake shuttle car traveling system, which belongs to the technical field of the shuttle car traveling system. Two sets of traveling systems are longitudinally arranged on both sides of the shuttle car, including a motor, a first-stage reducer, a rear transmission shaft and The front drive shaft, the motor is connected with the primary reducer, the primary reducer is connected with the rear wheel brake reducer through the rear drive shaft, and the rear wheel brake reducer is connected with the front wheel brake reducer through the front drive shaft , the primary reducer is provided with a parking brake; the wheel brake reducer includes the hub, the first bevel gear, the first bevel gear shaft, the second bevel gear, the second bevel gear shaft, the sun gear shaft, the sun gear, the planet wheel, planetary shaft, planet carrier, first shell, second shell, 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 a shuttle car traveling system, and specifically discloses a safe wheel-side braking shuttle car traveling system. 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 transmission system of the shuttle car mostly adopts a walking steering device of the rubber-tyred shuttle car described in the patent number ZL 200710062217.5, and the two sides are driven / braked separately. The drive shaft drives the drive shaft, the drive shaft drives the wheel reducer, the tire is installed on the wheel reducer, the wheel reducer close to the motor drives another drive shaft at the same time, and the drive shaft drives another wheel reducer away from the motor, The...

AI Technical Summary

Problems solved by technology

[0003] 1) Large braking impact: The brake is installed on the first-stage reducer, and the high-speed brake has a short service life; the brake has a large impact on the wheel-side reducer and transmission shaft, which may easily cause damage to the wheel-side reducer and transmission shaft;

[0004] 2) High-speed brakes are used. If a part of the low-speed brake is damaged, it will directly affect the braking performance of the shuttle car, posing safety hazards;

[0005] 3) The braking and deceleration are set separately, resulting in functional disconnection and incoordination, which brings safety hazards to the operation of the shuttle car
