Abstract

The utility model provides a half-shaft wheel train of a dynamic load testing stand of a rail car bogie. In the structure, a driving motor is fixed on a pedestal. The driving motor connects with a front half shaft through a front coupler. Two ends of the front half shaft are supported on two bearing pedestals. A rail wheel is fixed in the middle of the front half shaft. The rear end of the front half shaft connects with a rear half shaft through a middle coupler. Two ends of the rear half shaft are supported on another two bearing pedestals. Another rail wheel is fixed in the middle of the rear half shaft. A braking disc is fixed in the rear end of the rear half shaft. The braking disc is disposed between clamps of a brake. The half-shaft rail wheel train has high critical revolutions and low vibration at a high speed. The dynamic balance is easy to realize and the service lifetimes of bearings are long. The half-shaft rail wheel train is suitable for dynamic load tests of the high-speed bogie and is advance technical equipment in guaranteeing high-speed rail traffic safety.

Description

Rail vehicle truck dynamic test platform semiaxis track train
Affiliated technical field
The utility model relates to a kind of core component of rail vehicle test detecting equipment, especially a kind of rail vehicle truck dynamic test platform semiaxis formula track train.
Background technology
Bogie is the critical component of various rail vehicles, is directly connected to the normal operation and the safety guarantee of vehicle.Generally need load the dynamic test of running-in after the bogie assembling, detect the temperature rise situation and the shock conditions of motion-related parts, thereby confirm whether the bogie quality meets the requirements.External at present existing bogie dynamic test platform, the core component of this testing table is the track train, on the pressure wheel rail wheel of bogie, the rail wheel rotation drives wheel through friction force and experimentizes during test.External track train adopts the axis structure, and axle can produce amount of deflection when loading, and bigger vibration takes place when high speed; And axis has only two spring bearings; Bearing load is big, and the life-span is lower, and therefore the track train of this axis structure is not suitable for the dynamic loading experiments of typotron.Along with the fast development of Chinese track traffic high speed, increasingly high to the quality requirements of typotron, press for a kind of novel track train that can carry out dynamic test to typotron.
Summary of the invention
The purpose of the utility model provides a kind of track train of rail vehicle truck dynamic test platform of brand new, realizes the dynamic test of typotron.
For achieving this end, the technical scheme that the utility model is taked is following:
This rail vehicle truck dynamic test platform semiaxis formula track train is made up of base, motor, shaft coupling, semiaxis, rail wheel, bearing seat and clamping device.It is characterized in that on a base, fixing a drive motor; The drive motor axle is connected through the front end of a preceding shaft coupling and a half front axle; The two ends of half front axle are supported on respectively on two bearing seats, and a rail wheel is being fixed at the middle part of half front axle, and the rear end of half front axle is connected through the front end of intermediate shaft coupling with the back semiaxis; The two ends of back semiaxis are supported on respectively on two other bearing seat; The another one rail wheel is being fixed at the middle part of back semiaxis, and a brake disc is being fixed in the rear end of back semiaxis, and brake disc is between the clamp of detent.
The shape of two rail wheels is identical with size, and the curve form of rail wheel excircle is identical with the standard curved surface of railroad rail end face.
The profile of rail wheel is for crossing its central axis mid point and being symmetrical perpendicular to the plane of central axis.
Distance between the inner side end of two rail wheels equals to be tried the gauge of bogie.
During this rail vehicle truck dynamic test platform semiaxis formula track train wheel operation; Start drive motor; Drive two rail wheel rotations through preceding shaft coupling and intermediate shaft coupling; Two rail wheels rely on friction force to drive pressure bogie wheel above that again and rotate, just can carry out each item dynamic test.After experiment finished, detent started, clamp clamp brake disc make rail wheel and on wheel stop operating.
The beneficial effect of the utility model be following some, the one, the support distances of semiaxis is short, critical revolutions greatly improve; The one, the bending rigidity of semiaxis is high, behind the stand under load distortion little, little to dynamically balanced influence, vibration is little during high speed; The 3rd, rail wheel is a symmetric shape, is easy to realize transient equilibrium; The 4th, supporting bearing base quantity doubles than shaft type structure, and each bearing load reduces, and the life-span increases.Therefore this semiaxis formula track train is fit to the dynamic loading experiments of typotron, is the technical equipment that ensures an advanced person of high-speed rail transportation safety.
