Transverse shock absorber for locomotives

Abstract

The invention relates to a transverse shock absorber for locomotives, which belongs to the technical field of locomotives and comprises a pressure cylinder mounted in an oil storage cylinder. An oil return cavity is formed between the oil storage cylinder and the pressure cylinder, the pressure cylinder is peripherally matched with a piston on the head of a piston rod, and the piston rod extends out from the other end, away from a mounting end, of the oil storage cylinder and is fixedly connected with another mounting end with a dustproof tube. An end cover is fixed into the other end of the oil storage cylinder, a damping valve and a first one-way valve are mounted on the end cover and a bottom valve respectively, a second one-way valve is mounted on the piston, one end of the end cover is provided with a stepped hole, the bottom of the stepped hole is provided with a shrinkage hole which forms an annular groove with the piston rod, the shrinkage hole is communicated with the interior of the pressure cylinder, and a radial damping valve and an axial oil return pipe communicated with the oil return cavity are mounted on the end cover at the position corresponding to the shrinkage hole. The transverse shock absorber is high in processing and assembly manufacturability and more effective in damping, the compression damping force and the stretch damping force are basically uniform, and the symmetry rate can reach more than 90%.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a transverse shock absorber for a rolling stock, and belongs to the technical field of rolling stock. Background technique [0002] The shock absorber is an important device to attenuate the vibration of the vehicle suspension system. The function of the lateral shock absorber is to suppress the lateral movement of the car body relative to the bogie, as well as the yaw and shaking head vibrations, so as to attenuate the lateral vibration of the car body or carriage, significantly improve the comfort of riding on rolling stock, and reduce the wear and tear of related parts of the car , to ensure the safety of rolling stock operation. [0003] According to the applicant's understanding, the existing transverse shock absorbers can basically be divided into types with external protruding air bags and those without external protruding air bags. When the above typical structures are used, they not...

AI Technical Summary

Problems solved by technology

Although this technical solution has the characteristics of converting the vibration energy of the system into oil heat and dissipating it, the damping valve is installed in the inclined hole, which has poor manufacturability and is inconvenient when processing the guide seat and adjusting the damping force

And the end face seals used on both sides of the cylinder have a certain risk of leakage
