Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] attached image 3 An embodiment of the present invention is given, and it can be seen from the accompanying drawings that the present invention relates to a new type of support method for a rail vehicle anti-roll torsion bar system, which uses a multi-layer composite sleeve support method to support a rail vehicle Anti-rolling torsion bar system; the support method of the multi-layer composite sleeve is to cover the torsion bar shaft with a layer of steel sleeve with lower hardness than the material of the torsion bar shaft through interference fit, and the torsional friction generated during use The force is borne by the steel sleeve. Since the steel sleeve is made of relatively low hardness material, it can effectively protect the torsion bar shaft (the torsion bar shaft has high hardness and is very sensitive to surface defects. If it is scrat...

Abstract

The invention provides a method and device for supporting a side-roll torsion bar system of a railway vehicle. A multi-layer composite sleeve support method is used for supporting an anti-rolling torsion bar system of the railway vehicle. The multi-layer composite sleeve support method is as follows: a layer of steel bushing the hardness of which is lower than that of a torsion bar shaft material is sleeved on the torsion bar shaft by means of interference fit; the steel bushing is used for bearing torsional friction generated in the use process; the steel bushing is made of a material the hardness of which is relatively low, so that the torsion bar shaft can be effectively protected (because the hardness of the torsion bar shaft is high and the torsion bar shaft is sensitive to surface defects, the torsion bar shaft is easy to rapidly expand to be damaged if the torsion bar shaft is scratched in the use process); and a layer of friction resisting sleeve is sleeved outside the steel bushing, the outer diameter of the friction resisting sleeve and a support seat are in an interference fit structure, and the inner diameter of the friction resisting sleeve and the torsion rod shaft are in interference fit, thus ensuing that radial bearing can be provided and the torsional function of the torsion bar shaft can be successfully realized in the use process.

Description

technical field [0001] The invention belongs to a supporting method and device for components used in rail transit vehicles, in particular to a supporting method and a supporting device for an anti-rolling torsion bar system of a rail transit vehicle, which is installed between a rail vehicle body and a bogie. When the vehicle is rolling, the anti-roll torsion bar system and the secondary suspension of the vehicle together provide the rolling stiffness required for the safe operation of the vehicle, so as to meet the requirements of vehicle dynamic performance and ensure the safe operation of the vehicle. technical background [0002] The vibration of the vehicle mainly has degrees of freedom in six directions: stretching vibration in the X direction, yaw vibration in the Y direction, ups and downs vibration in the Z direction, nodding vibration around the Y axis, shaking head vibration around the Z axis, and sideways vibration around the X axis. Roll vibration. The current...
