Embodiment

[0023] A suspension bogie for a low-floor vehicle, the structure of which is as follows Figure 1-4 As shown, it includes a crankshaft 1, a frame 2, a wheel 3, an axle 4, an axle box 5, and a series of springs 6. The frame 2 is an H-shaped structure, with two crossbeams in the middle, and two wheel sets 3 with crankshafts, which are respectively connected with the four suspension frames of the frame 2 through the axle box 5, the primary spring 6, and the primary spring 6. The suspension frame 2 is arranged on the spring support of the axle box 5 and on the outside of the wheel 3 .

[0024] The wheels 3 on both sides of the front end of the frame 2 and the crankshaft 1 form an independent wheelset structure with a crankshaft, and the wheels 3 and the crankshaft 1 on both sides of the rear end also form an independent wheelset structure with a crankshaft.

[0025] The bogie of this new structural design uses an independent wheel set structure with a crankshaft, and innovatively...

Abstract

The invention relates to a low-scooter suspension-type bogie, which comprises a framework of an H-shaped structure, wherein the framework is hung on a spring support through four shaft box suspension seats, a shaft box spring structure consists of a shaft box body and laminated rubber, a way for supporting the outer side of the framework is adopted, and an independent wheel pair structure with a crankshaft is also used. Compared with the prior art, a unique bogie design structure that the framework is hung on a support is adopted. A lower gravity center of the bogie can be realized, so that a passage width of a floor inside a car body on the bogie on wheels can be further increased; and by adopting the independent wheel pair structure with the crankshaft, the guide performance and the running stability of the bogie can be improved compared with the independent wheel structure.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, in particular to a suspension bogie for a low-floor vehicle. Background technique [0002] Low-floor light rail vehicles refer to rail transit vehicles with a small height between the floor surface and the rail surface, generally below 350-400mm. The entrance height of this vehicle is very low, which makes getting on and off the vehicle very convenient, especially for the elderly, children and disabled patients. Low-floor light rail vehicles do not need to set up high platforms, and the tracks can be laid on the road, or use the original tram tracks, and the vehicles can pass through curves with a radius of about 20 to 50 meters, which is very suitable for urban ground road conditions. Therefore, low-floor rail vehicles with independent wheel bogie structures have become the first choice for light rail development in many European and American cities, among which 100% low-floor ve...
