(2) when the vehicle sinks, the sand or the mashed mud blown upwards props the auxiliary wheel, the auxiliary wheel automatically works, and the auxiliary wheel elastically deforms to provide a larger ground contact area and can continuously work together with the tire; the problems of tire knocking off, brake out of control and the like caused by the fact that tire air needs to be released in advance and is released when the automobile enters the same landform are avoided;

(3) when the vehicle bursts or sinks, the auxiliary wheel can automatically contact the ground, and the vehicle can be prevented from being suddenly out of control by replacing the tire;

(4) a plurality of auxiliary wheels can be overlapped for convenient storage;

(5) the characteristics that the lengthened screws and the auxiliary wheels can be installed in a superposed mode to reduce elastic deformation are utilized, the maximum outer diameter is enlarged, and the spare tire is replaced for emergency use, so that the adaptability, the practicability, the safety and the convenience of cross country are greatly improved.

As an improvement, the screw hole is not fixed in position and is selected according to the specifications of hubs of different vehicle types.

As an improvement, the tire at the ground contact part is designed by using rubber as a tire tread to increase the grip force.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the specific implementation of the invention, the off-road escaping auxiliary wheel comprises an auxiliary wheel mechanism 3, wherein the auxiliary wheel mechanism 3 is installed on one side of a wheel hub 5 through a fixing screw 2, the auxiliary wheel mechanism 3 comprises an installation combining part 15, and the installation combining part 15 is connected with a ground contact part 13 through a vertical supporting part 14;

the installation combining part 15 is drilled with a screw hole 8 matched with the specification of the fixed screw 2;

the main body of the vertical supporting part 14 is a spring steel wheel disc 7;

the tire rubber 1 is attached to the ground contact portion 13.

The position of the screw hole 8 is not fixed, and the screw hole is selected according to the specifications of the wheel hub 5 of different vehicle types.

The tire rubber 1 at the ground contact part 13 is designed into a tread pattern to increase the grip.

The rigidity and the elasticity of the auxiliary wheel mechanism 3 can be adjusted according to the thickness of the material so as to adapt to different use requirements.

The working principle of the invention is as follows: the main body of the device is an auxiliary wheel mechanism which is arranged on the outer side of the original wheel through a lengthened screw, the maximum outer diameter of the auxiliary wheel mechanism is slightly smaller than that of the original wheel, and the fact that the auxiliary wheel mechanism does not contact the ground when the auxiliary wheel mechanism runs on a normal road is guaranteed. The ground contact structure automatically contacts the ground when the original wheel sinks, the deformation is larger along with the deeper sinking, the ground contact area is increased along with the deformation, and better supporting force is provided to support the vehicle to continuously run. The method mainly comprises the following steps:

(1) mounting screws which are longer than the original tire fixing screws, wherein the mounting positions of the screws of the auxiliary wheel need to be made into different size types according to the mounting size of a vehicle type hub;

(2) the auxiliary wheel is made of elastic materials, the rigidity and the elasticity of the auxiliary wheel are designed according to the bearing capacity required by the vehicle, the auxiliary wheel is rigid inside and tough outside, the rigidity needs to have the supporting force for replacing a tire, and the elasticity needs to be restored to the original shape after continuous elastic deformation; a combination mode of spring steel and ground contact surface rubber is adopted;

(3) when the auxiliary wheel main body is made of non-wear-resistant materials, tire rubber is hung on the contact surface; the rubber of the ground contact part can be used as a tire pattern design to increase the grip.

The appearance and size of the auxiliary wheel can be changed according to the vehicle type, and the manufacturing material, basic structure and principle of the auxiliary wheel are unchanged.

A plurality of auxiliary wheels can be overlapped for convenient storage.

Note that: (1) when the auxiliary wheel is additionally arranged, attention needs to be paid to ensuring the strength of the original axle and ensuring the sufficient strength of the lengthened screw;

(2) because the auxiliary wheel is outwards expanded, the rotation range of the wheel is extended, and the driving safety needs to be noticed;

(3) when the auxiliary wheel is installed as an emergency wheel without an original wheel, attention is paid to checking the abrasion of the auxiliary wheel and checking a screw.
