Description

Rail train buffer

Technical Field

The utility model discloses a train accessories technical field relates to a rail train buffer.

Background

The buffer device is an important part on the train, mainly plays a role in buffering among various structural members, can effectively improve the running safety of rolling stock, and reduces the probability of train derailment accidents, thereby reducing the damage to the train structure and loaded goods. But the shock attenuation rubber that is used for rail train that has now supports often is difficult to absorb impact force and vibration effectively completely for rail train's the riding lacks the travelling comfort, and buffering shock attenuation effect is relatively poor, and in addition, the rubber node rigidity of current structure is general too big, can not be fine play shock attenuation buffering effect, influences passenger's travelling comfort.
