Abstract

The invention discloses a high speed rail vehicle as well as a bogie thereof and a wheel set driving device thereof. The wheel set driving device comprises a hollow axle, a driving wheel, a driven wheel and a driving brake unit, wherein the driving wheel is mounted at one end of the hollow axle, the driven wheel is mounted at the other end of the hollow axle, and the driving brake unit is mounted on the hollow axle; the driving brake unit is connected with the driving wheel through a connecting element so as to transmit a traction force and a brake force to the driving wheel; and the driving wheel transmits the traction force and the brake force to the driven wheel through the hollow axle. The high speed rail vehicle can singly pass through a 100 m small-radius curve and has good dynamics performance.

Description

technical field [0001] The invention relates to a high-speed rail vehicle, its bogie, and a wheel set driving device, belonging to the field of rail vehicles. Background technique [0002] The motor suspension of high-speed locomotive bogies at home and abroad adopts semi-body suspension or body suspension, and the secondary suspension uses rigid springs to make the vehicle have better dynamic performance. However, when the semi-body suspension or body suspension is adopted, the car body and the bogie are not easy to separate, and the vehicle maintenance is inconvenient. It is easy to maintain the car body and bogie when the elastic frame suspension scheme is adopted. If the second-series steel spring is continued to be used, the dynamic performance of the locomotive cannot meet the relevant requirements. Air spring + anti-roll device + anti-snake shock absorber + vertical The two-series scheme of shock absorber + height control valve can greatly optimize the dynamic perfor...
