Problems solved by technology

The V-shaped chute pair is sliding friction, and the whole platform has a relatively complex structure, so the friction resistance when measuring the platform movement and the resistance moment when rotating are both large, and the horizontal movement and rotation are not flexible, so it is difficult to accurately perform various tasks. The determination of the force value has not been used normally after installation

specific Embodiment approach

[0023] Fig. 1, 2, 3 show that a kind of embodiment of the present invention is:

[0024] A rail vehicle bogie parameter measurement platform, comprising a base 1 and a measurement platform 2 above the base, the base 1 is connected to the measurement platform 2 through a floating support seat 4 at the corner, and the specific connection of the floating support seat 4 is: the corner of the base 1 A support base plate 5 is fixed at the top of the support base plate 5, and a limit ring 6 is provided on or near the edge of the upper part of the support base plate 5. A steel ball cage 7 is placed on the support base plate 5 in the limit ring 6, and a steel ball cage 7 is placed in the steel ball cavity of the steel ball cage 7. Steel ball 8 is placed in it.

[0025] Figures 2 and 3 show that the four return rubber bands 9 whose ends are fixed on the limit ring 6 enclose the steel ball cage 7 in the middle of the support plate; the steel balls in the steel ball cavity of the steel ba...

Abstract

This invention disclosed a testing plate used for car bogie. The base of the plate connects to the measuring platform via a fulcrum bearing; the fulcrum bearing can be described like this: a bearing plate was fixed to the base, a spacing ring was placed on the bearing plate, a steel ball holding frame was set in the spacing ring, steel ball was placed in the cavity of holding frame and the upper side of the ball was connected to the platform.

Description

technical field [0001] The invention relates to a rail vehicle testing device, in particular to a rail vehicle bogie measuring platform. Background technique [0002] The main parameters of railway rolling stock bogies include vertical stiffness, longitudinal stiffness, transverse stiffness, slewing stiffness, anti-diamond stiffness and slewing friction torque, etc. The size and matching of each parameter determine the dynamic performance of the bogie. In line operation, it directly affects the running speed, smooth running comfort and safety reliability of the train. Therefore, it is very necessary for the bogie parameter detection device to accurately measure and study the main parameters of the railway rolling stock bogie. [0003] The parameter measurement of the rolling stock bogie is to fix the rolling stock bogie on a special measuring platform. According to the different items to be measured, a certain force is applied to the corresponding parts of the measured bog...
