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 ...
