Description
Technical field
The utility model belongs to vibration damper technical field, especially a kind of high-performance oleo-gear of rolling stock.
Background technique
Oil-pressure damper is a vitals in rolling stock.Owing between the wheel of rolling stock and rail surface being the contact of steel to steel, therefore, the irregularity of the irregular and track of wheel surface is all direct to be passed to sprung parts through wheel and gets on, and rolling stock each several part high and low frequency is vibrated.If this vibration decays without vibration damper, structural strength and the working life of mechanical part will be reduced, worsen riding quality.Its performance quality of oil-pressure damper directly has influence on Security and the travelling comfort of driving.
Especially in recent years China railways enters develop rapidly period, and particularly under the guide of Leap-forward Development of Railway policy, China railways will enter a brand-new developing stage.Due to the speed-raising of railway and developing rapidly of urban track traffic, highlight the demand to high performance hydraulic vibration damper, but traditional dydraulic shock absorber can't meet this demand.
Find following disclosed patent documentation through retrieval, concrete disclosure is as follows:
A kind of hydraulic damper (publication number: CN101311576), the document discloses this vibration damper by controlling the flow of the oil of filling hydraulic damper inside to carry out damping to the shock of the object from such as door.Described hydraulic damper comprises circle tube cylinder guide member, cylinder body, bar, piston and control gear.Circle tube cylinder guide member has a unlimited side, and cylinder body is formed as inserting in described cylinder body guide member with the drum that foundation and the contact of object optionally move around.Bar has the front end inserted in cylinder body and the rearward end supported at the internal surface place of cylinder body guide member.Piston is set to the front end of bar, and is formed as separating the inside of cylinder body to control the oily flow in cylinder interior.Control gear moves around along bar, and its king-rod passes control gear from the rear portion of piston.Control gear is formed as the interior separation of cylinder body optionally to control the volume of the back space at piston rear portion.
Find through contrast, above-mentioned documents and present patent application have relatively big difference in technological scheme.
