Background

Rolling stock is a collective term referring to all stock in rail transit. Both powered and unpowered, such as rail locomotives, rail vehicles, and passenger cars, are commonly included. Railway rolling stock represents in some cases a non-powered vehicle.

Oleo dampers are an important component on rolling stock. Because the wheels of the rolling stock are in steel-to-steel contact with the steel rail surface, the surface irregularity of the wheels and the irregularity of the rail are directly transmitted to the suspension part through the wheels, so that each part of the rolling stock vibrates in high frequency and low frequency. If such vibrations are not damped by the damper, the structural strength and the service life of the mechanical parts are reduced, and the operation quality is deteriorated. Its performance of oil pressure shock absorber directly influences the security and the travelling comfort of driving, oil pressure shock absorber controls the buffering shock attenuation because the mobile pressurization and the decompression of hydraulic oil in the use, and hydraulic oil is inside the cushion chamber, and the motion that hydraulic oil does not stop causes hydraulic oil can generate heat in the use for outside cylinder body subassembly is sent out and is scalded, and the unstable of hydraulic oil and cylinder body will influence the rolling stock shock attenuation at this in-process, consequently need us to improve according to the problem that appears more than.
