Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1 to Figure 4 , figure 1 It is a top view structural schematic diagram of the framework in a specific embodiment of the present invention; figure 2 for figure 1 Side view of the frame shown; image 3 for figure 2 Partial cross-sectional view of the frame shown; Figure 4 for image 3 Partial enlarged view of A.

[0026] The vehicle includes a bogie and a car body, and the car body is elastically supported on the bogie. The bogie specifically includes a frame, two or more pairs of wheels, and the frame is elastically supported on the axles of the wheels through spring suspension and other components.

[0027] The present invention provides a frame of a vehicle, which comprises a cro...

Abstract

The invention discloses a vehicle and a framework thereof. In the framework, the cross beams are supported and fixed on the side beams through the elastic fixing pieces; generally, the bogie comprisesa front wheel set and a rear wheel set. The side beams are respectively positioned on the front and rear sides of the cross beam; two end parts of the side beams are supported on axles of the front and rear wheel sets; in the driving process of the vehicle, when the front and rear wheels are positioned at different heights, the elastic fixing piece can generate elastic deformation; one end of each side beam can rotate by a preset angle relative to the connecting position of the side beam and the cross beam; therefore, the stress of the framework is in a balanced state; no deformation force isgenerated between the cross beams and the side beams, that is to say, the side beams where the wheels are located can generate displacement with the cross beam in the vehicle nodding direction through elastic deformation of the elastic fixing pieces. According to the connecting structure, the requirement for lifting one wheel is met, the wheel load reduction performance of the bogie of the framework is improved, meanwhile, rhombic deformation between the cross beams and the side beams can be eliminated through the framework in the connecting mode, the bogie formed by the framework is high inlinear speed, and especially the curve load reduction performance of the formed three-piece bogie is good.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and its frame. Background technique [0002] At present, the vehicle frame includes two side beams and a cross beam, and the beam is welded between the beams on both sides, that is, the two ends of the beam are respectively welded to the side beams on the corresponding sides to form an H-shaped frame, that is, an overall welded structure. [0003] The frame of the existing freight car is usually an integral welded structure, and the running circuit and application requirements are relatively special. Vehicles need to run intermittently between straight lines and curves. However, the frame of the overall welded structure transitions from a straight line to a curved section, or from a curved section to a straight line, and the load sharing capacity on the relief curve is poor, and the curve passing performance is poor, resulting in poor motion stability of the vehicle. ...
