Basic characteristics of Rubber Blocks:

　　（1） Rubber blocks are made by pressing multiple layers of Rubber Sheets. Has sufficient vertical stiffness to withstand vertical loads, can transmit the reaction force of the upper structure to the pier, has good elasticity to adapt to the rotation of the beam end; There is also significant shear deformation to meet the horizontal displacement of the upper structure.

　　（2） Characteristics of rubber blocks: They have been widely used in bridge construction, hydropower engineering, and building seismic facilities. Compared with the original steel bearings, rubber blocks have the advantages of simple structure, easy installation, steel saving, low price, simple maintenance, and easy replacement. Moreover, rubber block buildings have low height, which is beneficial for bridge design and cost reduction; It has a good seismic isolation effect, which can reduce the impact of live loads and seismic forces on buildings.

　　Rubber blocks, as an important shock-absorbing component, have been widely used in various machinery, automobiles, locomotives, and water transportation vehicles. Among them, rubber blocks for locomotives are a type of rubber product used in various parts of locomotives to reduce vibration, sound insulation, buffering and other functions. The rubber block is used as a rubber accessory. The structure of this product is relatively simple, including a rubber cone made in the center, axle box pull rod spring, side bearing rubber stack, elastic wheels, elastic gears, transmission device arch rubber blocks and ball joints, coupler rubber buffer blocks, etc. It is usually manufactured by molding.
