Description

Anti-skid wheel Technical Field The utility model relates to the technical field of anti-skid wheels, in particular to an anti-skid wheel. Background Conventional wheel slip measures rely primarily on driver action, such as timely deceleration or shifting to avoid wheel slip. However, this approach places high demands on the driver's skill and, under extreme conditions, there is still a risk of accidents. Especially under severe weather conditions such as wet skid, ice and snow, the wheel body of the vehicle is too smooth, and traffic accidents frequently occur because the wheel body cannot be prevented from slipping and losing control. The driving burden is caused to the driver, and the driving comfort and the driving confidence are improved. On complex road surfaces, such as mountainous areas, deserts, snow and ice or muddy terrain, wheels cannot be provided with the ability to adapt to different surface conditions. The diameter-variable wheels cannot be adaptively adjusted in diameter under different road conditions, helping the vehicle to provide optimal traction and stability on different roads. And the vehicle runs on a flat road surface, so that a large-diameter wheel body is driven to consume a large amount of energy, and a large amount of energy is wasted. Disclosure of Invention Aiming at the defects of the prior art, the utility model aims to solve the problems in the background art, and aims to provide the anti-skid wheel which can adjust the diameter of the wheel at any time according to the vehicle type and the road surface condition, can generate friction force, effectively grasp the ground and effectively save energy. The technical problem to be solved by the utility model is realized by the following technical scheme that the anti-skid wheel comprises a wheel body, wherein a plurality of radial sliding grooves are formed in one side of the wheel body along the circle center, strip-shaped notches are formed in the positions, located on the surface of the wheel body, of the sliding grooves, synchronous telescopic spokes are arranged in each sliding groove, arc-shaped wheels are arranged at the ends of the spokes, the outer contour of each arc-shaped wheel forms a clearance circle larger than the diameter of the wheel body, resistance teeth are arranged on the outer arc surface of each arc-shaped wheel, the resistance teeth can effectively cope with complex road conditions when the wheel runs, friction force of the contact surface of the wheel and the ground is increased, and when the wheel meets a road surface with poor road conditions, the resistance teeth maintain the stability of the wheel, and the risk of sliding or out-of-control is reduced. A gap is formed between the two arc-shaped wheel bodies, so that friction force can be increased in the moving process. The wheel body is provided with a driving mechanism for driving the spokes to synchronously stretch out and draw back, the driving mechanism comprises a large gear arranged at the center of a circle and positioned at one side of the sliding groove, the large gear is meshed with a small gear, the small gear rotates to drive the large gear to rotate, the large gear is provided with arc guide holes which are respectively arranged corresponding to the sliding groove, the arc guide holes are arranged along the same direction in a uniformly distributed mode along the circumferential direction, positioning guide posts are arranged in the arc guide holes and vertically hinged to the tail ends of the spokes, the positioning guide posts reciprocate along the length direction of the strip-shaped notch, and the spokes are driven to stretch out and draw back along the sliding groove. Spokes on the wheel body can be adjusted according to road conditions through a synchronous telescoping mechanism. The spokes in the sliding grooves can be extended or retracted as required, so that the area of the wheels contacting the ground is increased, and the traction force of the wheels on different road surfaces is improved. On wet slippery, icy and snowy road surfaces, the spokes can be stretched to increase friction and improve grip, while on flat dry road surfaces, the spokes can be retracted to reduce friction and improve running efficiency. Different vehicle types are provided with wheels with different diameters, the diameters of the wheels are adjusted in real time according to the running speed, the load and the road condition, and on complex roads, such as mountainous areas, deserts, ice and snow or muddy terrains, the diameter of the diameter-variable wheels can be adjusted under different road conditions, so that the vehicle can provide optimal traction and stability on different roads.
