Synchronous driving mechanism with single motor and coaxial two wheels for power bogie of 100% low-floor independent wheel

Abstract

A synchronous driving mechanism with single motor and coaxial two wheels for power bogie of 100% low-floor independent wheel is characterized in that: the driving mechanism comprises a traction motor, a transmission mechanism, and an independent wheel pair, the traction motor is vertically arranged and is in rigid connection with the transmission mechanism, the transmission mechanism comprises two gear boxes, the two gear boxes are arranged on two sides of the independent wheels, two gear boxes are in transmission connection with each other through the transmission shaft, both gear boxes are respectively connected to the two wheels which share the same shaft with them, and thus synchronous rotation of the independent wheel pair relative to the right wheel and the left wheel is achieved. Through the vertical arrangement of the traction motor and the whole rigid connection of the transmission mechanism, two gear boxes are in transmission connection with each other through the transmission shaft, both gear boxes are respectively connected to the two wheels which share the same shaft with them, thus synchronous rotation of the independent wheel pair relative to the right wheel and the left wheel is achieved, the transmission of driving force is achieved, the same self-steering characteristic of the independent wheel pair as the conventional rigid wheel pair is obtained, the wear of the wheel margin is reduced, and the safety and reliability of operation of the bogie are guaranteed.

Description

technical field [0001] The present invention relates to a 100% low-floor independent wheel power bogie driving method. Background technique [0002] The 100% low-floor light rail vehicle adopts an independent wheel axle bridge device in order to reduce the floor height of the whole vehicle. Unlike the traditional axle rigid wheel set, the two wheels on the same axle can rotate independently of each other. Therefore, when driving a When one wheel is turned, the other wheel will not turn synchronously, which will cause the vehicle to derail. In order to solve the above problems, some bogies adopt the same-side driving method, that is, a single motor and double-end output structure are used to drive the two wheels on the same side of the bogie through the front and rear gearboxes. Losing the inherent self-guiding characteristics of traditional bogies, the wheel flanges are often worn seriously, and derailment is prone to occur in the event of a motor failure on one side.
