Embodiment 1

[0041] figure 1 Shown in is a schematic structural diagram of a motor car bogie provided by an embodiment of the present application; figure 2 Shown in is a schematic diagram of the connection structure between the motor vehicle traction device and the frame provided by an embodiment of the application; please refer to Figure 1-Figure 2 .

[0042] This embodiment provides a motor car bogie 3, which includes a frame, a traction center pin 331 and a motor car traction device 33; wherein, the frame is the installation basis for the motor car traction device 33 and the traction center pin 331, and the frame includes two side beams 31 and Two crossbeams 32 and two sidebeams 31 extend along the length direction of the vehicle body. The two sidebeams 31 are parallel and oppositely arranged, and are respectively located at the edge of the frame. Two crossbeams 32 extend along the width direction of the vehicle body. The two crossbeams 32 can be arranged parallel and opposite to ea...

Embodiment 2

[0090] The rubber-tyred train provided in this embodiment includes a first car body and a second car body, the first car body can be a motor car body, the second car body can be an intermediate car body, and the bottom of the first car body is provided with a For the motor car bogie involved in Example 1, a trailer bogie is arranged between the first car body and the second car body. The motor car bogie and the trailer bogie are not only used to support the first car body and the second car body, but also Used to transmit traction between the first car body and the second car body.

Abstract

The embodiment of the present application provides a motor car bogie and a rubber-tyred train, which belong to the field of vehicle technology; it aims to solve the current problem that the traction center pin cannot rotate relative to the bogie, resulting in poor vehicle curve passing ability; the motor car bogie It includes two side beams, two beams, a traction center pin and a traction module arranged between the two beams; the traction module is provided with a longitudinal stopper, and the traction module is connected to the beam through the longitudinal stopper; the distance between the beams There are two transverse stoppers. The traction center pin includes the traction pin main body and the traction pin limit ears on both sides. One end of the traction pin main body is connected with the vehicle body, and the other end is inserted into the traction module. The traction pin One end of the limiting ear is inserted between the two transverse stoppers and has a movable gap. In the motor car bogie and the rubber-tyred train provided in the embodiments of the present application, the traction center pin can have a certain angle of rotation relative to the frame, which can improve the curve passing ability of the vehicle.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular, relates to a bogie for a moving train and a rubber-tyred train. Background technique [0002] The traction device and bogie of the motor car are important components in the structure of the rail vehicle. The bogie frame is the main structural part of the vehicle bogie. It not only bears the weight of all the equipment on the locomotive, but also transmits traction and bears various impact loads during the running process. . [0003] The motor car traction device includes a traction center pin, and the motor car traction device transmits the traction force to the bogie through the traction center pin; The bit structure is connected with the bogie frame to transmit traction; the bogie frame is also provided with a longitudinal stop limit structure connected with the traction center pin. [0004] However, the above-mentioned traction center pin cannot rotate relative ...
