Composition graphs 7, before tire 1 is blown out and when tire 2 is blown out, blow out shock absorber 3 in deployed condition, the output shaft being arranged in two-way cylinder 34 second air chamber B extends, connecting rod 33 launches, and connecting rod 33 drives wheel rim 32 to launch, when wheel rim 32 launches, the cross section of wheel rim 32 is disc, and has space 23 between the inwall of the outside face of wheel rim 32 and tire 2.
See Fig. 8, before tire 2 is inflated or before tyre inflating completes, shock absorber 3 of blowing out is in folded state, and the output shaft being arranged in the second air chamber B of two-way cylinder 34 shrinks, and connecting rod 33 folds, and wheel rim 34 folds.After tire 2 is inflated, under the effect of two-way cylinder 34 and connecting rod 33, shock absorber 3 of blowing out is converted to deployed condition by folded state.
In one implementation, the width of every section of wheel rim 32 can be set to and be less than or equal to 1/2 of rim 31 width, two sections of adjacent wheel rims 32 are positioned on the different discs of rim (by two connecting rods 33 that one section of wheel rim 32 connects, be arranged on the different disc of wheel hub 1 from two connecting rods 33 that adjacent one section of wheel rim 32 connects), and when shock absorber of blowing out is folded state, two sections of adjacent wheel rims 32 just contact with each other or are not in contact with each other mutually, with ensure blow out shock absorber be folded state time, two sections of adjacent wheel rims stagger mutually.In another kind of implementation, the width at the two ends of every section of wheel rim 32 can be set to 1/2 of rim width respectively, two sections of adjacent wheel rims 32 are positioned on the same disc of wheel hub 1, and when being folded state with the shock absorber that ensures to blow out, two sections of adjacent wheel rims stagger mutually.
