Function and characteristics of the rubber backing plate

The track rubber backing plate is cushioned under the rails. The rubber backing plate eases the pressure on the rails when the train is running, improves the safety factor, and also increases the service life of the rails and accessories. The track rubber pad is usually black, and there is a layer of steel plate inside the rubber pad, which increases the toughness of the rubber pad and ensures the quality of the rubber pad.
The rubber backing plate is made of oil-resistant rubber, which is mainly used for fixing the track of the reinforced concrete crane beam, and can also be used as a backing plate for the steel crane beam track. It has the performance of reducing the wear of the track top; reducing the impact of the crane on the crane beam; reducing the wear of the crane wheel rim; The friction force makes it difficult for the rail to move, and avoids or reduces the phenomenon that the gap between the rail and the crane beam is uneven along the same length of the rail. Thereby improving the stress situation of the pressure plate bolts. The section of the elastic composite rubber backing plate is slightly convex in the middle, so that the force is reasonable. The small rectangular convex strips on the backing plate are easy to deform, which not only makes the backing plate and the track easy to contact, but also increases the elasticity of the backing plate, which plays a shock-absorbing role.
A certain number of grooves are made on the contact surface between the track rubber backing plate and the track to reduce the internal stress under the wheel pressure and increase the friction between them; the four protruding feet on the rubber backing plate just clamp the bottom surface of the rail, so that the rubber The pad is always directly under the track without shifting. The "rubber pad" and the "upper tongue" of the pressure plate are an important part of the flexible track system.
