Problems solved by technology

However, since articulated trains are generally composed of two or more carriages, and the overall length of the train is large, there is a problem that the turning radius is too large, resulting in inflexible driving and turning on urban roads, which greatly limits the popularization and use of articulated trains

Embodiment 1

[0069] 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 .

[0070] 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

[0118] This embodiment provides a rubber-tyred train, which includes a first car body and a second car body that are oppositely arranged. The side of the first car body away from the second car body is provided with the motor car bogie as described in the first embodiment above. The first car body and the second car body are connected through a trailer bogie. Obviously, in this embodiment, the first car body is a motor car body, and the second car body can be an intermediate car body or a motor car body.

[0119] Since the rubber-tired train of this embodiment is provided with the motor car bogie described in the first embodiment above, it can simultaneously control the steering of the first motor wheel pair and the second motor wheel pair through a set of motor car steering drive device, ensuring that it is consistent with the steering of the motor car. The flexibility of the steering of the car body connected to the frame.

[0120] further, Figure 11 Shown in is the struc...

Abstract

The embodiment of the invention provides a bullet train bogie and a rubber-tyred train, the bullet train bogie comprises a framework, a first D-series high-speed train wheel pair, a second D-series high-speed train wheel pair and a D-series high-speed train steering driving device, and the framework comprises two oppositely arranged side beams and a cross beam connected with the two side beams; the first D-series high-speed train wheel pair comprises a first axle, and a first D-series high-speed train wheel and a second D-series high-speed train wheel which are arranged at two ends of the first axle; the second D-series high-speed train wheel pair comprises a second axle, and a third D-series high-speed train wheel and a fourth D-series high-speed train wheel which are arranged at two endsof the second axle; the D-series high-speed train steering driving device comprises a driving part and a transmission part, wherein the driving part is used for providing steering power; the transmission part is connected with the driving part, the first motor wheel pair and the second motor wheel pair and used for transmitting steering power provided by the driving part to the first motor wheelpair and the second motor wheel pair. According to D-series high-speed train bogie, steering of the two bullet train wheel pairs can be controlled at the same time through one bullet train steering driving device, and the steering flexibility of the D-series high-speed train body connected with the bullet train bogie is guaranteed.

Description

technical field [0001] The present application relates to vehicle manufacturing technology, in particular to a bogie for a motor vehicle and a rubber-tyred train. Background technique [0002] With the development of urban traffic construction, articulated trains (such as traditional low-floor trams, traditional trolleybuses, urban BRT trains, etc.) are gradually put into use to relieve road traffic pressure. An articulated train is a wheeled train composed of two or more carriages connected together by a hinge device. The articulated train changes its forward direction by the guidance of the hinge device between the carriages. [0003] In articulated trains, the steering system is used to control the direction of travel of the train, and the steering system should be able to keep the train running stably as required and flexibly change the direction of travel as required. However, since articulated trains are generally composed of two or more carriages, and the overall len...
