The inventor of the utility model had found by research and analysis, in the related technology, safety wheel in wheel tyre It is installed in a manner of axially connecting between multiple monomers by connectors such as pin, bolts.And since the diameter of safety wheel is much larger than wheel Tire internal diameter is being put into tire after the completion of can not first connecting between multiple monomers, is then needing that first multiple monomers are put into tire, then By being connected by connectors such as pin, bolts.And since the connectors such as pin, bolt connect multiple lists in a manner of axially connecting Body, then attended operation needs carry out in tire.Connection again since inside tires space is limited, between multiple monomers Journey becomes extremely inconvenient.For above-mentioned reason, inventor improves the structure of bogie, obtains the utility model Technical solution.

It is described in detail below with reference to Fig. 1-16 according to the safety wheel 100 of the utility model embodiment and with its wheel 200 and bogie 300.Safety wheel 100 is mounted in the tire 5 of wheel 200, when serious under-voltage or when blowing out, peace occurs for tire 5 100 certifiable wheels 200 of full wheel retain certain service ability.Wherein, wheel 200 can be the travelling wheel of bogie 300 303, the function of playing support bogie 300 and bogie 300 is driven to travel；Wheel 200 is also possible to the guiding of bogie 300 Wheel 3041 plays and provides the function of traveling guiding for bogie；Wheel 200 is also possible to the steady wheel 3042 of bogie 300, rises Lateral stability is provided to for bogie 300, prevents the function of rollover；Certainly, wheel 200 can also be other wheels, such as automobile Wheel etc..Wherein, directive wheel 3041 and steady wheel 3042 are belonging respectively to one kind of horizontal wheels 304.

As shown in figures 1 to 6, according to safety wheel 100 provided by the embodiment of the utility model, including at least two monomers, 10 He Connector 2.

As shown in figures 1-8, multiple monomers 10 generally arc-shaped structure, and multiple monomers 10 are sequentially connected, and form annulus Shape structure, the i.e. generally cirque structure of safety wheel 100.

The extending direction of the rotary shaft of safety wheel 100 is axially, i.e., in attached drawingxAxis extending direction, whereinxAxis positive direction To be preceding,xAfter axis negative direction is.It crosses the center of circle of safety wheel 100 and is periphery perpendicular to axial face.On the circumferential surface, with peace The center of circle of full wheel 100 is that linearly extended direction is radial direction to starting point outward, wherein being close to the direction in the center of circle of safety wheel 100 Interior, the direction in the center of circle far from safety wheel 100 is outer.It on the circumferential surface, is week around the direction that the center of circle of safety wheel 100 rotates To that is, in attached drawingwDirection, whereinwPositive direction is clockwise direction,wNegative direction is counterclockwise.

Due to the generally arc-shaped structure of monomer 10, so it is believed that monomer 10 is to extend to form along clockwise direction, then The starting point of extension is head end 10a, and the end of extension is tail end 10b.Monomer 10 is front and back symmetrical structure, therefore safety wheel After 100 relative to periphery overturning, the function of safety wheel 100 is not influenced, and the head end 10a of monomer 10 is original tail end at this time 10b, the tail end 10b of monomer 10 is original head end 10a at this time.

As Figure 7-9, monomer 10 includes inner ring wall 101 and collar wall 102.The head end 10a and tail end of each monomer 10 10b is equipped with connecting hole 103.Connecting hole 103 extends from inner ring wall 101 to collar wall 102, i.e. the opening of connecting hole 103 is located at On inner ring wall 101.As in Figure 3-5, connector 2 passes through the connecting hole 103 and another monomer of the tail end 10b of a monomer 10 The connecting hole 103 of 10 head end 10a, thus by the fixed company of the head end 10a of the tail end 10b of a monomer 10 and another monomer 10 It connects, so that multiple monomers 10 are fixedly connected sequentially, forms cirque structure.

Since connecting hole 103 extends from inner ring wall 101 to collar wall 102, i.e. the opening of connecting hole 103 is located at inner ring wall On 101, then after monomer 10 being put into tire 5, the opening of connecting hole 103 will be exposed to outside with the inner ring wall 101 of monomer 10, can Connecting hole 103 and another monomer that connector 2 passes through the tail end 10b of a monomer 10 are easily operated directly outside tire 5 The connecting hole 103 of 10 head end 10a, to be fixedly connected with the tail end 10b an of monomer 10 and the head end 10a of another monomer 10, And then multiple monomers 10 are in turn connected into cirque structure, the installation of safety wheel 100 is easily completed, safety is substantially increased The assembly efficiency of wheel 100 and wheel 200.
