Embodiment Construction

[0029] The present invention is mainly used in mine conditions of medium-thick coal seams, and is applied to heavy-duty shuttle cars (shuttle cars of 20t and above) with larger body height and width. Such as figure 1 As shown, the driving front axle and the driving rear axle of the shuttle car are driven / braked separately, that is, parallel control, and are respectively controlled by the drive system of the present invention. The drive system includes a motor A, a primary speed reducer B, a wheel edge Reducer IE and wheel reducer IIF, wheel reducer IE and wheel reducer IIF are symmetrically installed at both ends of the transverse drive shaft D of the corresponding shuttle car drive axle, and wheel reducer IE and wheel reducer IIF are located at On the inner side of the running rubber wheel L of the shuttle car, the wheel side reducer IE is connected to the output end of the first-stage reducer B through the transmission shaft C, and the first-stage reducer B is driven by the...

Abstract

The invention belongs to the technical field of design and manufacturing of underground coal mine subsidiary transport equipment parts, and provides a heavy shuttle car hub driving system integrating differential respective drive and wet-type brake. The problem that the existing shuttle car brake system is poor in steering differential function, large in brake impact and the like is solved. A drive front axle and a drive rear axle of a shuttle car are respectively controlled by two driving systems which are connected with each other in parallel; each driving system comprises a motor, a single-reduction gearbox, a hub reduction gear I and a hub reduction gear II; each hub reduction gear I and the corresponding hub reduction gear II are symmetrically mounted at two ends of a transverse transmission shaft of a corresponding shuttle car drive axle, and are positioned on the inner side of a corresponding walking rubber wheel of the shuttle car; the hub reduction gears I are connected with an outputting end of the single-reduction gearbox through transmission shafts; and the single-reduction gearbox is driven by the motors. By the two driving systems which are connected with each other in parallel, problems of abrasion of tires, eccentric load of the hub reduction gears and the like are solved, and motor power utilization rate is improved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of parts of underground auxiliary transportation equipment in coal mines, and in particular relates to a heavy-duty shuttle wheel side drive system integrating differential speed transfer and wet braking. Background technique [0002] At present, domestic and foreign shuttle cars mostly use figure 2 The wheel side transmission system shown adopts the method of driving / braking separately on both sides, and the motor drives the first-stage reducer on both sides, the first-stage reducer drives the transmission shaft, the drive shaft drives the wheel side reducer, and the tire is installed on the wheel. side reducer. The wheel reducer close to the motor simultaneously drives another drive shaft, which drives the other wheel reducer farther away from the motor. [0003] The motors are placed on both sides of the shuttle car, and the reducers on the two wheels are longitudinally arrange...
