Embodiment Construction

[0026] refer to figure 1 , The bogie of the present invention is generally assembled by a frame device 1, a wheel-to-axle box positioning device 2, a foundation braking device 3, and a secondary suspension device 4. The frame device 1 is the main structure of the bogie, and other components are assembled on the frame device through bolt connection.

[0027] refer to figure 2 , the frame device 1 is generally welded 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 two mounts are a composite casting integrated structure, and their respective functions are obtained through secondary overall processing; at the end of the side beam structure 101, there is a composite mount 105 for a secondary horizontal and vertical shock absorber, which is welded to the main structure Connection: A magnetic rail stopper...

Abstract

The invention relates to an unpowered bogie for a 100-percent low-floor light rail vehicle. The unpowered bogie is characterized in that a primary spring mounting seat and a secondary spring mounting seat of a side beam structure are of a composite integrated structure; a secondary transverse and vertical shock absorber compound mounting base is welded at the end part of a side beam; a brake hoisting seat, a gearbox hoisting seat and a magnetic rail stopping and blocking seat are welded on the outer side of the side beam; an elastic wheel set which adopts a rigid straight shaft and has a diameter phi of 500-600 is adopted, and two elastic wheels are assembled with a vehicle axle together through interference fit; vertical shock absorbers and transverse shock absorbers are arranged at four corners of the bogie. The unpowered bogie has the advantages that through the design of a novel high-strength and high-reliability framework structure, the bearing capacity of the whole bogie is improved, and meanwhile, the structure is compact, and the maintenance is simple and easy; through a novel wheel set and axle box device structure, the wear speed of a tread is improved, and the service lives of the wheels are prolonged; meanwhile, through the newly-designed unpowered bogie, the interchange with a power bogie is realized to a maximum extent. The unpowered bogie comprises wheels, wheel axles, an axle box and other key parts, and greater convenience is provided for repair and maintenance.

Description

technical field [0001] The present invention relates to the field of rail vehicles, in particular to a 100% low-floor light rail vehicle rigid axle type unpowered bogie. Background technique [0002] At present, 100% non-powered bogies for low-floor light rail vehicles basically adopt shaftless bogies and independent wheel bogies. In this situation, it is urgent to develop a new type of unpowered bogie structure. For light rail vehicles, the non-power bogie and the power bogie will be used together, so the newly designed structure of the non-power bogie needs to be interchangeable with the newly designed power bogie to the greatest extent, while the existing products Neither are interchangeable with newly designed power steering racks. Contents of the invention [0003] The purpose of the present invention is to provide a new type of rigid wheel-set bogie product applied to 100% low-floor light rail vehicles. Compared with independent wheel bogies, this product can solve...
