Walking driving speed reducer integrating wheel edge braking

Abstract

The invention provides a walking driving speed reducer integrating wheel edge braking, and belongs to the technical field of shuttle car braking speed reducers. The walking driving speed reducer comprises a hub, a first bevel, a first bevel gear shaft, a second bevel gear, a second bevel gear shaft, a sun wheel shaft, a sun wheel, a planet wheel, a planet wheel shaft, a planet carrier, a first shell, a second shell, an inner gear ring, a static friction plate, a dynamic friction plate, a piston, a reset screw, a reset spring, an annular transition connecting plate and a limiting steel sheet. According to the walking driving speed reducer, the planet carrier and the transition connecting plate are designed in a split mode, so that the installation and maintenance of a wet braking part are facilitated, the replacement of the friction plates can be realized only by disassembling a tire and the transition connecting plate, the whole planet carrier and parts such as the planet wheel associated with the planet carrier do not need to be disassembled when the friction plates are replaced, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of brake speed reducers for shuttle cars, and specifically discloses a travel drive speed reducer integrating wheel side brakes. 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. Patent No. ZL201510635944.0 discloses a heavy-duty shuttle wheel side deceleration braking system integrating differential speed transfer and wet braking. The wet brake is integrated, but the planetary carrier is directly connected to the outer shell of the wheel-side wet brake. When the friction lining wears out and needs to be replaced, the outer shell of the wheel-side wet brake, the entire planetary carrier, and the planetary wheels associated with the planetary carrier need to be remove...

Patent No. ZL201510635944.0 discloses a heavy-duty shuttle wheel side deceleration braking system integrating differential transfer and wet braking. The wet brake is integrated, but the planetary carrier is directly connected to the outer shell of the wet brake at the wheel. When the friction lining wears out and needs to be replaced, the outer shell of the wet brake at the wheel, the entire planetary carrier, and the planetary wheels associated with the planetary carrier need to be removed.
