Technical Field

The invention relates to the technical field of transmission belts, in particular to a belt of a beach vehicle, and a formula and a processing method thereof.

Background

The belt of the dune buggy is an important part in the dune buggy, belongs to friction transmission and transfers power by means of friction force between the belt and the belt wheel. In addition, the belt of the beach vehicle is also a speed-changing belt, and the acceleration and deceleration of the beach vehicle are realized by changing the diameters of the driving wheel and the driven wheel, namely the transmission ratio is steplessly adjusted. The whole beach vehicle runs by the power transmitted by the belt, the conditions are very harsh, and the requirements of common belts are difficult to meet.

In order to avoid the belt slipping during transmission, certain tension must be applied to the belt during transmission so as to generate positive pressure friction force for transmission. The belt is continuously bent and extruded in high-speed operation, the V belt is easy to heat under the action of friction force, the higher the rotating speed and the higher the load, the higher the temperature rise, the belt becomes soft when the temperature rises, the transverse rigidity is also obviously reduced, and the belt turns on the side and fails.
