Straddle type monorail vehicle double-shaft power bogie with differential mechanism

Abstract

A straddle type monorail vehicle double-shaft power bogie with a differential mechanism comprises a support, a walking wheel assembly and a power device. The walking wheel assembly and the power device are both arranged on the support. The power device supplies drive force to the walking wheel assembly. The straddle type monorail vehicle double-shaft power bogie is characterized in that the walking wheel assembly is composed of a half shaft, a hollow-core shaft, a wheel core, two inner bearings, two outer bearings, two rim bevel gears, four planet gears, a planet carrier, two limiting bearings, two rims and two wheels. The straddle type monorail vehicle double-shaft power bogie has the technical beneficial effects that by means of the straddle type monorail vehicle double-shaft power bogie with the differential mechanism, energy consumption generated when a straddle type monorail vehicle turns can be effectively lowered, and abrasion to the wheels is reduced.

Description

Technical field [0001] The invention relates to a straddle-type monorail vehicle driving technology, and in particular to a straddle-type monorail vehicle biaxial power bogie with a differential. Background technique [0002] The existing straddle-type monorail transportation vehicle power bogie generally consists of a bracket, two sets of running wheel assemblies and two sets of power devices. In the running wheel assembly, two wheels are provided on the same drive shaft. To drive the two wheels to rotate synchronously; the problem is: when the straddle-type monorail vehicle passes through a curve, due to the difference in turning radius, the distance that the wheels on one side need to move will be greater than the distance that the wheels on the other side need to move. distance. Since the two wheels are driven by the same drive shaft, the rotation angular speed of the two wheels is the same. This causes both wheels to be in a slipping state of rolling and sliding when pa...

Problems solved by technology

[0002] The existing straddle-type monorail traffic vehicle power bogie generally consists of a bracket, two sets of running wheel assemblies and two sets of power devices. In the running wheel assembly, two wheels are arranged on the same drive shaft, and the drive shaft to drive the two wheels to rotate synchronously; the problem is that when the straddle monorail vehicle passes through the curve, due to the difference in the turning radius, the distance that the wheels on one side need to move will be greater than the distance that the wheels on the other side need to move distance, since the two wheels are driven by the same drive shaft, the rotational angular velocity of the two wheels is the same, which causes the two wheels to be in a slipping state while rolling and sliding when passing through the curve, and the wheels in the slipping state , will not only increase energy consumption, but also accelerate the wear of the wheels, resulting in shortened service life of the wheels and increased operation and maintenance costs
