The device adopts the mode of installing on wheel hub, and is different completely with current antiskid design. When the design is adopted, the antiskid device is not directly contacted with the rubber surface of the tire, so that the rubber part of the tire can be effectively protected. In addition, because this application antiskid major structure adopts rigid structure, and the tire can the atress warp with the part on ground, and the side projection under the tire user state is not a perfect circle, so should be able to change relative deformation along with the tire tread when this rigid structure antiskid is atress.

The present example provides a basic embodiment, which is only based on the basic principle of the solution of the invention and is not a limitation of the solution of the invention.

Referring to fig. 19-25, the attached drawings provide various angle views and use state views of the car hub fixed ice and snow road surface antiskid disc of the present invention. The main body part is a floating disc 1, the fixed positioning part is a floating disc positioning base 6, and the functional part mainly comprises anti-skid nail feet 2 and capsule air pressure damping components (such as a short capsule air pressure damping component 4 and a long capsule air pressure damping component 5). The floating disc 1 is installed on a wheel hub through a floating disc positioning base 6, and when the tire runs forwards, the floating disc 1 rotates along with the tire, so that the antiskid nail feet 2 are continuously contacted with the ground. Spacing is arranged between the anti-skid nail feet 2 and the floating disc 1, and the capsule air pressure damping assemblies (4 and 5) are arranged between the anti-skid nail feet 2 and the floating disc 1, so that the anti-skid nail feet 2 generate certain pressure with the ground, the anti-skid surface of the anti-skid nail feet 2 prevents the floating disc 1 from sliding on the ground, and the anti-skid effect of the tire is also realized.

Specifically, to achieve the above functions, the main components thereof should at least include:

(1) a floating disc 1. The floating disc 1 is fixedly connected with a floating disc positioning base 6. The positions and the number of the floating disc positioning bases 6 correspond to the spokes of the hub. The floating disc positioning base 6 is provided with a fastening device which can fasten the floating disc positioning base 6 on the spoke. The outer side of the floating disc 1 is provided with a plurality of bent blade-shaped limiting grooves 102, the bent blade-shaped limiting grooves 102 are used for limiting the movement of the anti-skid nail feet 2 and playing a limiting role, and anti-skid nail foot positioning holes 105 are arranged in the bent blade-shaped limiting grooves 102.

(2) And (4) anti-skid nail feet 2. The anti-skid nail feet 2 are connected with the floating disc 1 through the anti-skid nail foot positioning holes 105 to form a rotating pair, and the rotation of the anti-skid nail feet 2 is limited by the bent knife-shaped limiting grooves 102. The contact surface of the non-skid stud feet 2 and the ground is provided with a plurality of non-skid studs 202.

The bladder air pressure damping assembly provides damping to the cleat 2 as the cleat 2 is compressed under force.

Second embodiment

On the basis of the first embodiment, the present example improves the details to provide some preferred implementation devices.

(1) In the first embodiment, although the capsule pneumatic damping component can provide damping for the stud 2, in the compression process of the stud 2, the floating disc 1 and the rotating pair formed by the stud 2 are easy to cause the contact part between the stud 2 and the capsule pneumatic damping component to slide relatively, so that the capsule pneumatic damping component is damaged. To this end, the present example first provides an improvement to the air pressure damping assembly of the capsule.

Referring to fig. 12 and 13, the improved capsule pneumatic damping assembly of this embodiment includes a compressed and resilient capsule pneumatic damping assembly body (e.g., a short capsule pneumatic damping assembly body 401) having a guide wheel 403 at one end, in this embodiment, a guide wheel bearing. Referring to fig. 6, the inner side of the anti-skid nail foot 2 is provided with a slideway, so that when the anti-skid nail foot 2 is stressed and compressed, the guide wheel 403 can slide along the slideway on the inner side of the anti-skid nail foot 2.
