Guide wheel device for rail vehicle and method for adjusting position of guide wheel

Abstract

A guide wheel device for a rail vehicle, comprising a guide wheel cooperating with a track to guide the car body, a base connected to the car body, and a vibration damping assembly elastically supporting the guide wheel, characterized in that the vibration damping assembly spans along the direction of the track It is erected on the front and rear sides of the guide wheel. The axle of the guide wheel is fixed at the center of the shock absorber assembly. The shock absorber assembly is elastically connected to the base. During driving, the guide wheel follows the elastic movement of the shock absorber assembly on the base and keeps guiding with the track. Cooperate. The invention prolongs the service life of the guide wheel, improves the effectiveness of guide cooperation between the guide wheel and the track, ensures the support of the guide wheel to the vehicle during the operation of the vehicle, and improves driving safety. Reduce the tilt angle of the vehicle during the turning process, and improve the guiding reliability of the guide wheel in the operating condition of the vehicle. The invention also provides a method for adjusting the position of the guide wheel of the guide wheel device for rail vehicles.

Description

Technical field [0001] The present invention relates to a guide wheel device for rail vehicles and a guide wheel position adjustment method thereof, belonging to the technical field of rail vehicles. Background technique [0002] At present, the maglev train, the air rail, the suspension vehicle is in the operation, and the vehicle body requires a guide wheel to guide or enter and exit, the guide wheel is required to prevent the vehicle from tilting. . [0003] In order to avoid the guidance wheel to prevent the guide wheel, the guide wheel and the rails generally use the gap to cooperate. Due to the case of construction errors and wheel wear, there will be uneven gaps, when the gap is too large. , Causing a phenomenon of excessive or tilt in the left and soone of the vehicle body; when the gap is too small, the guide wheel friction is abnormal, and the guide wheel is scrapped in advance. In the existing guide wheel, the casing speed is slow, it is not easy to slave, often in the...

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.
