Problems solved by technology

[0002] Pneumatic tires meet people's needs for more comfortable and energy-saving vehicles in terms of performance, but there are also disadvantages, that is, they are easily penetrated by sharp objects, that is, tire blowouts, once similar situations occur, not only pose a threat to the driving safety of the vehicle Serious threats, but also bring a lot of trouble to the use of vehicles; air-free solid tires can solve the problem of safe use, and its long service life and low deformation rate make it more widely used, but free of charge Pneumatic solid tires also have disadvantages such as poor shock resistance and low comfort, and their ability to adapt to road surfaces is poor, and they are easy to feel bumps on rough roads, so it is necessary to design shock absorption for the wheels of non-pneumatic tires

Embodiment 1

[0025] Such as figure 1 As shown, the present invention provides a shock-absorbing hub for a non-pneumatic tire, including a hub body, the hub body includes an outer ring 1 and an inner ring 2 arranged concentrically, a buffer portion is arranged between the outer ring 1 and the inner ring 2, and the outer ring 1 and the inner ring 2 are provided with a buffer. There is a certain gap between the ring 1 and the inner ring 2. When the outer ring 1 receives a radial impact, it can be buffered by the buffer part, so that the outer ring 1 has a certain space for movement in its radial direction, so it can play a role in buffering and The role of shock absorption.

[0026] Preferably, the distance between the buffer part and the left and right side walls of the outer ring 1 is the same, so that the buffer part can achieve better shock absorption effect; Belt 32 and the clamping ring 21 positioned on the outer circumferential surface of inner ring 2, the width of the first buffer zo...

Embodiment 2

[0037] On the basis of Embodiment 1, the outer ring 1, the inner ring 2 and the buffer part 3 are all made of carbon fiber. The hub made of carbon fiber has multiple advantages such as lighter weight, high strength, high modulus, low density, small linear expansion coefficient, etc., and has two characteristics of strong tensile strength of carbon material and soft processability of fiber.

[0038] In summary, the present invention provides a shock-absorbing wheel hub for a non-inflatable tire. By setting a buffer between the outer ring 1 and the inner ring 2, it can make up for the lack of return force of the non-inflatable solid tire; when the outer ring 1 After being subjected to radial impact, there will be a certain activity space, so it can play the role of cushioning and shock absorption, and improve the driving stability during driving; an elastic member 4 is set between the outer ring 1 and the inner ring 2, and through its own The elastic deformation can prolong the ...

Abstract

The invention relates to a damping wheel hub of an air inflation-free tire. The damping wheel hub comprises a wheel hub body, wherein the wheel hub body comprises an outer ring and an inner ring in a concentric way; a buffer part is arranged between the outer ring and the inner ring, and a certain gap is reserved between the outer ring and the inner ring. The damping wheel hub has the advantages that when the outer ring suffers from the radial shock, a certain movement space is formed, so that the buffering and damping functions are realized; by arranging the elastic part between the outer ring and the inner ring, the force action time is prolonged, and the damping function is realized.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a shock-absorbing wheel hub for an air-free tire. Background technique [0002] Pneumatic tires meet people's needs for more comfortable and energy-saving vehicles in terms of performance, but there are also disadvantages, that is, they are easily penetrated by sharp objects, that is, tire blowouts, once similar situations occur, not only pose a threat to the driving safety of the vehicle Serious threats, but also bring a lot of trouble to the use of vehicles; air-free solid tires can solve the problem of safe use, and its long service life and low deformation rate make it more widely used, but free of charge Pneumatic solid tires also have disadvantages such as poor shock resistance and low comfort. They have poor adaptability to road surfaces and are prone to bumps on rough roads. Therefore, it is necessary to design shock absorption for the wheels of non-pneumatic tires. ...
