Problems solved by technology

[0006] Aiming at the limitations of the prior art, the present invention aims to provide a rail vehicle and its forced-to-radial bogie. The forced-to-radial bogie can realize the radial direction of the wheels through a simple structure, and the working principle is simple and convenient. , especially for bogies with complex structures and tight spaces, it not only solves the problem of radial eccentric wear of bogies, but also occupies a small space

Embodiment Construction

[0023] 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.

[0024] The forced-direction radial bogie of this embodiment is a radial bogie capable of realizing radial action at curves. The forced radial bogies, such as figure 1 , figure 2 , image 3 As shown, it includes radial rod 1, axle box body 2, frame side beam 3, wheelset 4, traction rod 5, traction sleeve 6, frame beam 7, traction pin 8, car body 9 and other components.

[0025] One end of the radial rod 1 is connected with the traction sleeve 6 of the...

Abstract

The invention discloses a rail vehicle and a forced steering radial bogie thereof. The forced steering radial bogie comprises a bogie body which is connected with a vehicle body through a traction device; the traction device is connected with a shaft box body of each wheel pair through a radial rod in a hinging manner; the bogie body generates one displacement amount in the transverse direction through a centrifugal force generated by the vehicle body at a curved line part; and the displacement amount drives the radial rods to act on the shaft box bodies of the wheel pairs through deviation of the traction device, so as to force an included angle theta to be formed between front and rear wheel shafts. By adopting the rail vehicle and the forced steering radial bogie thereof, the radial eccentric wear problem of the bogie is solved and a small space is occupied.

Description

technical field [0001] The invention relates to a rail vehicle and a forced-steering radial bogie thereof, belonging to the field of rail vehicle design. Background technique [0002] Radial bogie technology is a technology suitable for rail transit rolling stock in areas with many curves, because it can make the wheelset deflect radially relative to the curve, resulting in many advantages. [0003] A traditional rolling stock bogie is a rigid bogie that holds the front and rear wheel sets. The rotation angle of the wheel set relative to the frame at the curve is small and negligible, therefore, at the small curve, an angle of attack is caused between the wheel set and the rail. This angle of attack can realize the curve guidance of the vehicle, but it also increases the wear of the wheels and rails, increases the noise, and produces adverse effects. [0004] There are many kinds of existing radial bogie technologies, such as a locomotive radial bogie disclosed in Chinese ...
