Novel transverse elasticity positioning method of side-rolling resistant torsion bar for railway vehicle and device of method

Abstract

The invention provides a novel transverse elasticity positioning method of a side-rolling resistant torsion bar for a railway vehicle. A groove is formed at each of assembling ends of a supporting seat and a torsion arm; an elastic thrust pad is arranged between the supporting seat and the torsion arm for transverse elasticity positioning; and the two ends of the elastic thrust pad are fixed on the supporting seat and the torsion arm by bolts or pins respectively for achieving circumferential positioning, and ensuring no circumferential movement during torsion or shearing. The method achieves no transverse impact or transverse motion in a using process of the side-rolling resistant torsion bar for the railway vehicle, and the elastic thrust pad and a torsion bar component are subjected to torsional deformation simultaneously, and bear a vertical load and an impact load, so that a side-rolling resistant function, a shock absorption function and a noise reduction function of the side-rolling resistant torsion bar for the railway vehicle are ensured.

Description

technical field [0001] The invention relates to a vehicle positioning method and a positioning device, in particular to a lateral positioning method of an anti-rolling torsion bar of a rail vehicle and a device for realizing lateral positioning. Background technique [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 bogies of rail transit vehicles are all two-stage suspensions, and the anti-roll torsion bar system plays a role in adjusting the roll stiffness of the vehicle and controlling the roll vibration of the vehicle. [0003] The mechanism motion diagram of the anti-roll torsion bar system is as follows: figure 1 As shown, M in the figure is the car body, E and F are c...
