Description

Technical Field

[0001] The utility model relates to a five-piece mining truck wheel. Background Art

[0002] A mining truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. The working characteristics of a mining truck are short distance and heavy load. Large electric shovels or hydraulic shovels are often used for loading, and the truck travels back and forth between the mining site and the unloading site. Wheels refer to rigid wheels that fix the inner edge of the tire, support the tire, and bear the load together with the tire. The tire, rim, and spoke that are combined together are collectively referred to as wheels. The wheels of mining trucks are one of the important parts of mining trucks. In mining transportation, wheels are also important for ensuring driving safety and reducing transportation costs.

The adjustable mine car wheel is provided with an adjusting device inside the wheel, when installing the axle, only the end of the axle needs to be installed into the circular hole in the middle of the adjusting device, and the adjusting device is provided with a high-energy spring, the size of the circular hole can be automatically adjusted to adapt to the size of the axle, and the clamping block is clamped with the axle, and the versatility is very strong.

[0004] Referring to the above-mentioned adjustable mine truck wheel, the rim of the adjustable mine truck wheel adopts an integrated bending molding structure, and the rim of the integrated bending molding structure is prone to deformation and tearing, which makes the comprehensive performance of the rim not good enough. In addition, during the transportation of the mine truck, the friction between the tire and the ground is easy to generate a lot of heat, especially in the high temperature in summer, the mine truck wheel travels on the high temperature ground, which will also cause the temperature of the mine truck wheel to rise. If the heat in the mine truck wheel cannot be dissipated, it is easy to cause a tire blowout during transportation. Therefore, how to better improve the comprehensive performance of the rim and better dissipate the heat of the mine truck wheel is an important problem that needs to be solved in the design of the mine truck wheel.
