Problems solved by technology

[0003] The anti-roll torsion bar is usually installed on the web of the side beam or the cross beam. However, due to the space problem of the bogie during the train development process, the anti-roll torsion bar needs to be installed at the bottom of the side beam of the bogie, and there is structural strength at the bottom of the side beam. and insufficient stiffness

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0023] Such as figure 1 As shown, an anti-roll torsion bar installation structure is applied to the installation of the anti-roll torsion bar 4 in rail vehicles. The installation structure includes two installation seats 1, which are respectively arranged at the bottom of two side beams 2 of the bogie, and the anti-rolling torsion bar 4 is suspended and installed at the bottom of the two installation seats 1. The anti-roll torsion bar 4 mainly includes a torsion bar mechanism 5 and a link mechanism 6. The link mechanism 6 is provided with a link seat 7 to be fixed with the car body, and the torsion bar mechanism 5 is provided with a support seat 8 to be fixed with the bogie. In the example, the support base 8 is fixed to the bottoms of the two installation bases 1 .

[0024] Such as Figure 2 to Figure 4 As shown, in this embodiment, the side...

Abstract

The invention relates to an anti-lateral-rolling torsion bar installing structure and a bogie applying the same. An installing base is arranged at the bottom of a side beam of the bogie, and an anti-lateral-rolling torsion bar is fixed at the bottom of the installing base. The anti-lateral-rolling torsion bar installing structure is simple in structure, and the problems of the strength and rigidity required by the anti-lateral-rolling torsion bar installation are effectively solved by utilizing a box-shaped structure of the installing base, so that the anti-lateral-rolling torsion bar can be installed at the bottom of the side beam. By means of the irregular box-shaped structure, stress concentration of the installing base is relieved, and breakage of the installing base is prevented. A large installing space is reserved in the bogie, and the railway vehicle bogie design performed by a technician is facilitated.

Description

technical field [0001] The invention relates to an installation structure, in particular to an anti-rolling torsion bar installation structure and a bogie using the structure. Background technique [0002] During the operation of rail vehicles, there are six degrees of freedom of movement: stretching vibration in the X-axis direction, yaw motion in the Y-axis direction, ups and downs in the Z-axis direction, nodding motion around the Y-axis, shaking head around the Z-axis Movement, roll motion around the X axis. At present, rail vehicles use anti-roll torsion bars to adjust the roll stiffness of the vehicle, that is, to suppress the roll motion around the X-axis. [0003] The anti-roll torsion bar is usually installed on the web of the side beam or the cross beam. However, due to the space problem of the bogie during the train development process, the anti-roll torsion bar needs to be installed at the bottom of the side beam of the bogie, and there is structural strength at...
