Embodiment 1

[0045] figure 1 Shown in is the structural diagram of the trailer bogie provided by an embodiment of the application; please refer to figure 1 . This embodiment provides a trailer bogie 4, which is installed under two adjacent first and second car bodies, not only for carrying the first and second car bodies, but also for Traction force is transmitted between the first vehicle body and the second vehicle body. Wherein, the first car body can be a motor car body, and the corresponding second car body can be an intermediate car body; or, the first car body can be an intermediate car body, and the corresponding second car body can be a motor car body; Alternatively, both the first vehicle body and the second vehicle body are intermediate vehicle bodies.

[0046] Specifically, the trailer bogie 4 includes a first frame body 41 and a second frame body 43; wherein, the first frame body 41 is used for connecting the first vehicle body, and the second frame body 43 is used for conn...

Embodiment 2

[0132] This embodiment provides a rubber-tired train, comprising: a first car body and a second car body opposite to the first car body, and the trailer as described in the first embodiment is passed between the first car body and the second car body Bogies are connected.

[0133] The rubber-tired train in the embodiment of the present application connects the adjacent first car body and the second car body through the trailer bogie involved in the first embodiment above, so that the first axle and the second axle can be close to the end of the car. The edge and the end part of the vehicle no longer need to be designed to adapt to the strong force structure such as traction force and braking force, which reduces the design difficulty of the end part of the vehicle; at the same time, it avoids the occupancy of the passenger space in the end area of ​​the vehicle by the axle, and can realize a low floor.

[0134] The rubber-tired train of this embodiment connects the adjacent fi...

Abstract

The embodiment of the invention provides a trailer bogie and a rubber-tired train, belongs to the technical field of rubber-tired trains, and aims to solve the problems of deformation and displacementof a through passage and overlarge rotation angle, and the trailer bogie comprises a first frame body, a second frame body and a rotary support device; the first frame body and the second frame bodyare rotationally connected through a rotary supporting device. The rotary supporting device comprises a rotary supporting cover plate. The rotary supporting cover plate is arranged at the top of the first frame body, two through channel limiting bosses are arranged on the side, away from the first frame body, of the rotary supporting cover plate, and a through channel limiting space is formed between the two through channel limiting bosses. According to the trailer bogie and the rubber-tired train provided by the embodiment of the invention, the deformation displacement and the rotation angleof the through channel can be limited, the deformation amount and the rotation angle of the through channel are prevented from being too large, and therefore the comfort of passengers can be improved.

Description

technical field [0001] The present application relates to the technical field of rubber-tyred trains, in particular to a trailer bogie and rubber-tyred trains. Background technique [0002] Low-floor trackless vehicles have the advantages of large vehicle marshalling capacity, low entrance and easy access, making them play an increasingly important role in urban traffic. [0003] In the low-floor trackless vehicle, the bogie is the most important structural component, and its structure and various parameters directly determine the stability of the vehicle and the comfort of the ride. The through passage can change displacement along the forward direction of the vehicle and turn within a certain angle range along with the running process of the vehicle (for example, acceleration, deceleration, turning, etc.). [0004] However, the existing vehicles do not have a restrictive effect on the above-mentioned displacement change and turning angle of the passageway, resulting in ex...
