Embodiment Construction

[0029] refer to figure 1 , The bogie of the present invention is composed of a frame device 1, a wheel-to-axle box positioning device 2, a transmission device 3, a foundation braking device 4, and a secondary suspension device 5. The power transmission form is a vertical right-angle transmission structure form from the output shaft of the motor to the input shaft of the gearbox, and then transmitted to the wheels through gear transmission.

[0030] refer to figure 2 , the frame device is welded together by two side beam structures 101 and two beam structures 102. In the side beam structure 101, a series of spring mounting seats 103 and a secondary spring mounting seat 104 are designed according to functional requirements. The seat is a composite casting integrated structure, which obtains its respective functions through secondary overall processing; at the end of the side beam structure 101, there is a composite mounting seat 105 for secondary horizontal and vertical shock ...

Abstract

The invention discloses a power bogie for a 100% low-floor light rail vehicle. The power bogie is mainly formed by assembling and combining a frame device, a wheel set axle box positioning device, a driving device, a foundation brake device and a secondary suspension device, wherein the wheel set axle box positioning device adopts a rigid straight axle and an elastic wheel set with diameter between 500mm and 580mm, and the two elastic wheels and the axle are assembled together through interference assembly; the driving device, a gear case and the foundation brake device are compounded and assembled together; a primary spring installation base and a secondary spring installation base are of a composite integral structure, thus forming the running gear of the wheel set type 100% low-floor vehicle with the rigid straight axle; meanwhile, other parts are optimized and improved for cooperatively using, so that integrated innovation of the power bogie product for the 100% low-floor vehicle is achieved, and the innovated structure can solve the problems that the existing bogie on the same type of vehicle is low in carrying capacity, quick in abrasion of tread and relatively weak in maintainability.

Description

technical field [0001] The present invention relates to the field of rail vehicles, in particular to a 100% rigid axle power bogie for low-floor light rail vehicles. Background technique [0002] At present, 100% bogies for low-floor light rail vehicles basically adopt the shaftless bogie type, independent wheel bogie type, independent wheel left and right coupling and longitudinal coupling types, but each type has great differences in structure, operation and maintenance. Insufficient, such as the limited bearing capacity of the shaftless bogie, the faster wheel wear of the independent wheel and the shorter repair period, and the complex structure of the longitudinal and lateral coupling of the independent wheel is not easy to maintain. Rigid shaft non-independent wheel bogie, because of its traditional wheel-rail vehicle running characteristics, plays a very good role in improving wheel tread wear and wheel eccentric wear of the same wheel set. Therefore, it is very neces...
