Abstract
A synchronous driving mechanism with two motors and two wheels for power bogie of 100% low-floor individual wheel is characterized by comprising a traction motor, gear transmission devices, and individual wheel pairs, the motor shaft is taken as the traction power source and is connected to the input shaft of the gear transmission mechanism through a shaft coupling, the gear transmission device is arranged on the outer side of the framework of the bogie, a umbrella gear is arranged on the input shaft of the gear transmission mechanism, the umbrella gear engages with the other umbrella gear on the middle shaft, a middle shaft gear is arranged on the middle shaft, the middle shaft gear engages with the gear on the output shaft, and the primary output shaft is connected to the wheels. The driving torque, which is transmitted from the traction motor to the gear transmission device, can be transmitted to the wheels trough the gears, synchronous driving of the two coaxial traction motors is always taken as the control aim, when one of the two motors breaks down, the other motor stop outputting immediately, thus synchronous driving of coaxial two wheels of individual axle bridge device is achieved, the synchronous driving mechanism has certain self-guiding characteristic, so the wear of the wheels is reduced, the possibility of derail because of motor breakdown is avoided, and the operation safety of the individual wheel axle bridge is improved.
Description
Technical field
The present invention relates to a kind of use at 100% low-floor light rail vehicle mechanism of independent wheel to the coaxial two-wheeled synchronous drive mechanism of the double-motor on power truck.
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 in a certain side electrical fault situation, derailment accident occurs easily.
Summary of the invention
The object of the invention is to realize the transmission of propulsive effort, mechanism of independent wheel is taken turns identical self-steering characteristics having with conventional rigid, 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% coaxial two-wheeled synchronous drive mechanism of low floor mechanism of independent wheel power truck double-motor, it is characterized in that: comprise traction electric machine, gear system, mechanism of independent wheel pair, each wheel arranges cover motor and a gear system, coaxial two motor driven in synchronism, motor shaft is as the traction power source, input shaft by shaft coupling transmission connection teeth wheel drive mechanism, gear system is arranged in outside truck frame, establish a bevel gear on the input shaft of gear drive, another bevel gear engagement on this bevel gear and tween drive shaft, also establish a countershaft-gear on tween drive shaft, countershaft-gear and output shaft gear engagement, the one-level output shaft connects wheel.
the present invention is passed to the driving torque of gear system from traction electric machine can be by gear transmission to wheel, all the time take two coaxial traction electric machine driven in synchronism as controlling target, when the arbitrary motor et out of order in coaxial two motors, another motor stops power output immediately, realized the coaxial two-wheeled driven in synchronism of independent axle Biodge device, it is had with tradition the shaft type rigid wheel is arranged to identical wheel rail relation feature, has certain self-steering characteristics, thereby reduction wheeling edge wearing, avoided simultaneously because of electrical fault cause derailing may, improve independent axle bridge safety in operation.
Description of drawings
