Guide wheel device for railway vehicle and guide wheel position adjusting method thereof

Abstract

Provided is a guide wheel device for a railway vehicle. The device comprises guide wheels which are matched with a rail to guide a vehicle body, a base connected with the vehicle body, and a vibrationreduction assembly which elastically supports the guide wheels. The device is characterized in that the vibration reduction assembly stretches across the front side and the rear side of the guide wheel in the rail direction, a wheel shaft of the guide wheel is fixed to the center of the vibration reduction assembly, the vibration reduction assembly is elastically connected with the base, and theguide wheel is kept in guide fit with the rail along with elastic movement of the vibration reduction assembly on the base in the traveling process. The service life of the guide wheel is prolonged, the effectiveness of guide matching of the guide wheel and the rail is improved, supporting of the guide wheel to a vehicle in the vehicle running process is guaranteed, and driving safety is improved.The inclination angle of the vehicle in the turning process is reduced, and the guiding reliability of the guiding wheel in the vehicle running working condition is improved. The invention further provides a guide wheel position adjusting method of the guide wheel device for the railway vehicle.

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.
