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
The present invention relates to a kind of 100% low floor mechanism of independent wheel power truck type of drive.
Background technology
100% low-floor light rail vehicle is in order to reduce the car load height of floor from rail top, adopted the independent axle Biodge device, there is the axle rigid wheel to different to be from tradition, two wheels on same axletree can be separate rotation, therefore, when driving a wheel, another wheel can synchronously not rotate, and will cause vehicle derailing.In order to address the above problem, some bogie trucks have adopted the homonymy type of drive, namely adopt the structure of single motor, both-end output, drive two wheels of bogie truck the same side by former and later two gears case, but this type of drive makes it lose the intrinsic self-steering characteristics of conventional bogie, often wheeling edge wearing is serious, and easily derails in a certain side electrical fault situation.
Summary of the invention
The purpose of this invention is to provide a kind of 100% low-floor light rail vehicle mechanism of independent wheel power truck list motor coaxle two-wheeled synchronous drive mechanism, can either realize the transmission of propulsive effort, make again mechanism of independent wheel to having with the conventional rigid wheel identical self-steering characteristics, reduce wheeling edge wearing, guarantee bogie truck property safe and reliable to operation.
For achieving the above object, the invention provides a kind of 100% low floor mechanism of independent wheel power truck list motor coaxle two-wheeled synchronous drive mechanism, it is characterized in that: comprise traction electric machine, transmission device, mechanism of independent wheel pair, traction electric machine is vertically arranged and is connected with the transmission device integral rigidity, transmission device comprises two gears case, be arranged in mechanism of independent wheel to the left and right sides, two gears case connect by transmission shaft driven and connect separately two coaxial wheels, realize that mechanism of independent wheel is to two of left and right wheel synchronous rotary.
Transmission device comprises two gears case, the gear case that is connected with traction electric machine comprises input shaft, a pair of bevel gear, one-level tween drive shaft, one-level countershaft-gear, one-level output shaft gear, one-level output shaft, one-level transmission gear, transmission shaft output gear, a pair of bevel gear is arranged on respectively on input shaft and one-level tween drive shaft, one-level countershaft-gear and one-level output shaft gear are meshed, the one-level transmission gear is arranged on one-level tween drive shaft opposite side, one-level transmission gear and the engagement of transmission shaft output gear; Another gear case comprises secondary input gear, secondary tween drive shaft input gear, secondary tween drive shaft, secondary tween drive shaft output gear, secondary output shaft gear, secondary output shaft, secondary input gear and the engagement of secondary tween drive shaft input gear, secondary tween drive shaft output gear and the engagement of secondary output shaft gear; Two gears case connect by transmission shaft driven.
