Adaptive guide wheel device and design method for rail vehicles

Abstract

Self-adaptive guide wheel device for rail vehicle and design method thereof, comprising guide wheel cooperating with track guide, wheel axle installed on guide wheel, base connected with car body and shock absorber assembly connected between wheel axle and base , which is characterized in that the number of the shock absorber assemblies is multiple and symmetrically arranged at both ends of the wheel axle, the shock absorber assemblies are arranged obliquely, and the shock absorber assemblies expand and contract between the wheel axle and the base with the movement of the vehicle body and / or Or swing to adapt to the operating conditions, make the guide wheel and the track maintain a guide fit and support the wheel shaft to keep vertically arranged to prevent the guide wheel from tilting. The invention improves the guiding effectiveness of the guide wheel, prolongs the service life of the guide wheel, realizes the self-adaptation of the guide wheel relative to the track, and reduces the pressure wear or inclined eccentric wear of the guide wheel due to the bending and inclination of the track or the rising of the car body , The guiding reliability of the guide wheel is higher, and the inclination angle of the car body is limited to prevent the car body from over-tilting and improve driving safety.

Description

technical field [0001] The invention relates to a guide wheel device for rail vehicles and a method for adjusting the position of the guide wheel, and belongs to the technical field of guide wheels for rail vehicles. Background technique [0002] At present, during the operation of maglev trains, empty rail cars, and suspension cars, the car body needs guide wheels to guide forward or when entering and leaving the station, guide wheels need to be guided to prevent the vehicle from tilting. . [0003] The guide wheel device of the traditional structure is to avoid the jamming phenomenon caused by excessive force on the guide wheel, and the gap between the guide wheel and the track is generally used. Due to construction errors and wear of the wheel body, the gap will be uneven. When the gap is too large , resulting in excessive left and right swing or inclination of the car body; when the gap is too small, the friction of the guide wheel is abnormal, and the guide wheel is sc...

Problems solved by technology

[0003] The guide wheel device of the traditional structure is to avoid the jamming phenomenon caused by excessive force on the guide wheel, and the gap between the guide wheel and the track is generally used. Due to construction errors and wear of the wheel body, the gap will be uneven. When the gap is too large , resulting in excessive left and right swing or inclination of the car body; when the gap is too small, the friction of the guide wheel will be abnormal, and the guide wheel will be scrapped in advance

In the existing guide wheel device, the straightening speed is slow, it is not easy to straighten, and the situation of non-guiding often occurs. When the car body is turning, the angle of inclination is too large and there is danger.
