Problems solved by technology

[0005] However, the above two bogies still have the problems of large curve radius and unsatisfactory running wheel wear. Therefore, a new design technology that can integrate the two technologies of single-axle bogie and double-axle bogie is needed. The advantages of both

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0029] An articulated rail vehicle bogie such as figure 1 , figure 2 , image 3 As shown, what is different from the general bogie is that its frame 3 is designed with a hinge device 9 to realize the formation of an angle between the first wheel shaft 14 and the second wheel shaft 15 . The bogie of the present invention is mainly composed of rubber tires 1, secondary springs 2, frame 3, drive axle 4, primary air springs 5, primary leaf springs 8, trac...

Abstract

The invention discloses a hinged railway vehicle bogie and a railway vehicle. The hinged railway vehicle bogie comprises a non-integral framework which is formed mainly by hinging a first portion to a second portion. A first wheel axle is installed on the first portion of the framework, a second wheel axle is installed on the second portion of the framework, and the first wheel axle and the second wheel axle form an included angle when the railway vehicle passes a curve. According to the hinged railway vehicle bogie and the railway vehicle, the accessible curve radius is small, the eccentric wear of a walking wheel is less, and the maintenance cost is low.

Description

technical field [0001] The invention relates to an articulated rail vehicle bogie and a rail vehicle, belonging to the field of rail vehicle design. Background technique [0002] Compared with my country's urban rail transit, which generally adopts the traditional steel wheel-rail rail transit system, the rail transit system using rubber tires has good wheel-rail adhesion, strong climbing ability, short braking distance, and small vibration. , low noise and other advantages, it is more and more widely used in urban rail transit and airport lines. [0003] There are two types of existing rubber-tyred vehicle bogies. One is a single-axle bogie, which has a small radius of curves, small tire eccentric wear, low maintenance costs, and low construction costs. There are disadvantages such as small passenger volume and low transportation efficiency. The other is the double-axle bogie, which has the advantages of high load and high transportation efficiency, but has the disadvantag...
