Embodiment
In order to which the technical solution of the utility model is explained further, it is described in detail below in conjunction with the accompanying drawings.
Referring to figs. 1 to Fig. 2, a kind of runflat vehicle wheel construction, including take turns frame 10, the inner tube of a tyre being arranged in wheel frame 10
30 and the cover tire 20 that is fastened in wheel frame 10, cover tire 20 is coated on outside the inner tube of a tyre 30, and the inner tube of a tyre 30 can for the heat of foamed expansion
The solid carcass of plasticity.
As a kind of preferred embodiment of the utility model, it is described wheel frame 10 be equipped with the first collar 11, the second collar 12 with
The first card is formed and abutment face 15, the first collar 11 and the second collar 12 are oppositely arranged, between the first collar 11 and abutment face 15
Groove 13, forms the second card slot 14 between the second collar 12 and abutment face 15, in the utility model, wheel frame 10 can use existing fill
Wheel mount structure in air filled tyre, need to only remove the air inflation nozzle in existing pneumatic tire.The cover tire 20 includes and the first card slot
13 the first holding sections 21 coordinated, the second holding section 22 coordinated with the second card slot 14 and it is formed in the first holding section 21 and the
