Workshop vibration damping device for rail vehicle and rail vehicle

Abstract

The invention provides a workshop vibration damping device for a rail vehicle and the rail vehicle. The workshop vibration damping device comprises a first mounting seat, a second mounting seat, a vibration damper, a connecting rod assembly and a rotating arm. The first mounting seat comprises a first mounting plate and a first supporting seat, wherein the first supporting seat is mounted on one side of the first mounting seat. The second mounting seat comprises a second mounting plate, a second supporting seat and a third supporting seat, wherein the second supporting seat and the third supporting seat are mounted on the second mounting plate. The vibration damper is arranged in parallel between the first mounting plate and the second mounting plate, the second supporting seat is hinged to one end of the vibration damper, and the other end of the vibration damper is hinged to one side of the first supporting seat. One end of the connecting rod assembly is hinged to the other side opposite to the first supporting seat, and the other end of the connecting rod assembly is hinged to one end of the rotating arm. The other end of the connecting rod assembly is hinged to one end of the rotating arm, and the third supporting seat is hinged to the other end of the rotating arm. Transverse stoppers are arranged on both sides, in the rotating direction of the rotating arm, of the third supporting seat so as to limit the rotating angle. According to the workshop vibration damping device for the rail vehicle and the rail vehicle, the relative motion between two adjacent carriages can be attenuated, transverse vibration reduction is realized, and the maximum lateral displacement is limited.

Description

technical field [0001] The invention relates to the technical field of rail vehicle vibration reduction, in particular to a rail vehicle workshop vibration reduction device and a rail vehicle. Background technique [0002] Each car of the rail vehicle is set on the track through two bogies, and the two cars are connected by a coupler. During the operation of the rail vehicle, the car is prone to lateral movement and shaking. In order to improve the running performance of the vehicle, the bogie Generally, a transverse stop structure is provided, that is, a pair of transverse stoppers are set between the traction pin and the frame to limit the lateral displacement of the vehicle beyond the normal degree of freedom. The existing transverse stopper is vulcanized by rubber and carbon steel, and is fixed on the transverse stopper mount by bolts, and the transverse stopper mount is fixedly installed on the frame of the bogie. With the further development of rail vehicles, the pass...

AI Technical Summary

Problems solved by technology

With the further development of rail vehicles, the passenger capacity and riding comfort of trains have been increased, and higher requirements have been put forward for the dynamic performance of vehicles. Setting lateral and lateral stops has been unable to meet the requirements.

[0003] At present, there is no technology for rail vehicles to install a vibration damping device in the gap outside the two cars to limit the lateral displacement between the two cars and achieve lateral vibration reduction.
