Description

technical field

[0001] The invention relates to a single-axle rubber-tyred light rail vehicle bogie, which belongs to the technical field of the overall structure of rail transit bogies. Background technique

[0002] In the field of rail transportation technology, the rubber tire track system has the advantages of low noise, small vibration, and high ride comfort because it adopts the tire technology of road transportation instead of steel wheels and rails in the traditional rail transportation field; at the same time, it has high Adhesion, the vehicle has a strong climbing ability, and the maximum slope can reach 10%; the vehicle has a high ability to pass through a small curve radius, and can adapt to complex terrain. Domestic cities such as Guangzhou, Beijing and Tianjin have some applications. The bogie of the existing rubber-tyred vehicle adopts the leaf spring bearing method, which is heavy and rigid, and cannot continue to improve the riding comfort; the drawbar of t...
