Transverse stopper with high stability

Abstract

The invention provides a transverse stopper with higher stability, a wear-resisting plate of the transverse backstop is provided with a boss made of the same material as the wear-resisting plate, the boss and the wear-resisting plate are integrated, and the boss extends into a rubber part and is integrally formed with the rubber part of the transverse backstop through vulcanization, therefore, the contact area between the wear-resisting plate and the rubber part is increased. The bottom plate is further improved, and a rotation stopping step is arranged on or below the bottom plate, so that the bolt or the nut is prevented from rotating, and the fastener is prevented from loosening. Under the condition that the performance of the rubber backstop is not affected, the structures of the wear-resisting plate and the bottom plate of the rubber backstop are improved, the problems that the wear-resisting plate is prone to falling off, and the bottom plate fastener is prone to loosening are solved, and the using stability of the transverse backstop in the actual working condition is improved.

Description

technical field [0001] The present invention relates to vehicle vibration damping components, and more particularly, to a lateral stopper with high stability. Background technique [0002] Rubber stopper is a commonly used rubber-metal composite damping and limiting element, which can be widely used in various damping and limiting places, especially in the bogies of rolling stock. [0003] When rail vehicles such as subways are running on underground, ground and elevated lines, due to construction line factors, they often pass through some small curve radii, which can easily cause vehicle lateral movement. In order to avoid dangerous conditions such as vehicle rollover, the bogie Both are equipped with a lateral stop structure, which is installed on the inner side of the bogie frame to limit the lateral displacement of the car body, mainly bear the lateral load, ease the lateral rigid impact, and improve the lateral vibration performance of the car body. [0004] One end of...

Problems solved by technology

[0007] In the present invention, the boss is integrated with the wear-resistant plate and extends into the rubber part. Adding the boss is equivalent to increasing the vulcanization area of ​​the wear-resistant plate and the rubber part, improving the bonding strength of the wear-resistant plate, and solving the problem of The problem that the wear plate is easy to fall off
