Method for increasing the contact area (6) of a wheel (1) with a rim (2) having at least one expandable element (7) in the area of ​​a rim (2) of the wheel (1), wherein the expandable element (7) is brought from a rest state to an expanded state by filling it with a fluid, in which the running surface (10) of the wheel (1) is widened completely, wherein the expandable element (7) is arranged in the rim (2) in such a way that the width of the wheel (1) or of a vehicle equipped therewith is not increased, characterized in that the expandable element (7) comprises a three-dimensional textile support structure.

3D flexible spikes mounted on running wheels or drive wheels. Their highly flexible design significantly reduces the problem of contamination and improves traction. The combination of mounting and suspension also considerably reduces manufacturing costs. Current research indicates that numerous flexible spikes exist, and their properties can be further customized. In all applications, the spikes are guided in a reversible direction and held flexibly on this axis by mechanisms. See our European patent application EP23197209.2. A comprehensive prior art search has already been conducted for this application. In this version, the spikes are mounted three-dimensionally (Fig. III flexible working paths, items 10, 11, 12, and 16). This means the spikes are flexible in all directions and their working path can be restricted by guides, including adjustable guides. These wheels are typically used as drive wheels, where permanently optimized traction is beneficial. Due to the individual adjustment of the spikes, balancing is difficult, and the wheels with flexible spikes should be used at low speeds. The spikes' flexibility in all directions allows the wheels to adapt to ground conditions and facilitates cleaning. The 3D design significantly reduces damage and wear on the spikes. In conjunction with a guide (optionally adjustable) on the vehicle / equipment, the properties of the spikes can be influenced at different positions on the wheel.

The application relates to the field of wheel anti-skid technology, in particular to an anti-skid wheel and a vehicle, the anti-skid wheel comprising a tire, a wheel rim and a plurality of anti-skid mechanisms arranged in the wheel rim, the plurality of anti-skid mechanisms being arranged along the circumference of the wheel rim; each anti-skid mechanism comprises a support, an anti-skid part, a moving part, a fixing shaft and a connecting rod; the support is fixed to the wheel rim; the moving part can move along the support, and the fixing shaft is fixed to the support; the two ends of the connecting rod are movably connected with the anti-skid part and the moving part respectively, and the middle part of the connecting rod is movably connected with the fixing shaft; the moving part can move along the support, drive the anti-skid part to rotate around the fixing shaft, and make one side surface of the anti-skid part tightly contact the outer side surface of the tire; the other side surface of the anti-skid part is provided with anti-skid lines. According to the anti-skid wheel and the vehicle, the problem that the existing vehicle is difficult to travel in the case that the road surface is very slippery in ice and snow weather or in a muddy road section during the traveling process is solved.

This utility model provides a wear-resistant and anti-slip device for mining machinery wheels, belonging to the technical field of wear-resistant and anti-slip devices. It includes a rotating rod with a rotating shaft on its side. A threaded rod and a nut are fixedly installed on the right side of the rotating shaft. A side plate and a wheel body are provided on the side of the rotating shaft. A retaining plate is provided inside the wheel body. An mounting plate and a baffle are fixedly installed on the top of the retaining plate. An anti-slip pad is fixedly installed on the top of the mounting plate. A protective plate is fixedly installed on the right side of the mounting plate. This allows for flexible adaptation between components, facilitating quick disassembly and maintenance. The retaining plate and the soft pad combine to form an adaptive buffer layer. Combined with the anti-slip pad with a drainage groove on its surface, it effectively improves grip under wet and slippery conditions and guides mud and sand. The reinforcing rod strengthens the rigidity of the wheel body structure. The threaded rod and nut pair provide precise clearance adjustment, enabling the device to adapt to dynamic load changes under complex geological conditions. Overall, it exhibits high durability, strong environmental adaptability, and convenient maintenance characteristics.
