Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.

It is to be understood that this description is made only by way of example and not as a limitation on the scope of the utility model.

Referring to fig. 1 to 7, a PU hollow tire with strong elasticity comprises a hub 1 and a tire 2 mounted on the hub 1, wherein the tire 2 is made of a PU material; a buffer cavity 3 is arranged in the tire 2, a fixing groove 4 is arranged at the center of the inner ring of the tire 2, and the fixing groove 4 is communicated with the buffer cavity 3, so that the elasticity and the stability of the tire are improved; the outer ring center department of wheel hub 1 is provided with fixed muscle 5, and after the assembly, fixed slot 4 with the laminating of fixed muscle 5 increases the frictional force between tire 2 and the wheel hub 1 reduces mutual displacement in the use.

The outer lane bilateral symmetry of wheel hub 1 is provided with spacing muscle 6, the both sides of tire 2 be provided with spacing portion 7 that spacing muscle 6 is corresponding, after the assembly, spacing portion 7 with spacing muscle 6 laminating prevents the risk of off tracking takes place for tire 2 in the in-process of using.

The width of fixed slot 4 is less than the width of fixed muscle 5, after the installation, fixed muscle 5 with fixed slot 4 belongs to interference fit, further improves the frictional force between tire 2 and wheel hub 1.

The height of the fixing rib 5 is slightly smaller than the depth of the fixing groove 4, so that the situation that the wheel hub 1 is damaged due to the fact that the ground is in rigid contact with the wheel hub when the tire is seriously deformed due to overlarge vehicle-mounted weight in the use process of a vehicle is avoided.

The outer ring of the tire 2 is provided with a plurality of anti-skidding grooves 8, so that the friction force between the tire 2 and the ground is increased.

Spacing muscle 6 with form the ascending tire chamber 9 of opening between the fixed muscle 5, the installation degree of difficulty is low, and adjustment easy operation, simple structure, light in weight, intensity are good.

The bottom of the tire cavity 9 is arc-shaped, so that the installation space of the tire 2 is increased, the volume of the tire 2 is further increased, and the safety performance of the tire 2 is improved.

The hub 1 further comprises a spoke portion 10 and a central portion 11, wherein the spoke portion 10 comprises a plurality of spokes 12, and the spokes 12 are circumferentially arranged around the central portion 11.
