Description
Technical field
The utility model relates to a kind of wheel safety component.
Background technology
High capacity vehicle is prevent from blowing out, improve safety many employings band tyre of vehicle operation.But there is the shortcomings such as expensive, deadweight is comparatively large, damping property is poor, control sensitivity is low in band tyre compared with air-inflation tyre.Therefore, air-inflation tyre is adopted to replace band tyre to be the important trend that high capacity vehicle develops.For eliminating the danger of running out the way when air-inflation tyre is blown out, rollover, rim for automobile wheel installs supporter, is conventional effective means.Supporter is three-chip type or multiple-piece unitized construction, is connected between supporter split by bolt or connecting strap.At present adopt processes the displacement that mode that annular recess matches with the annular projection on supporter inner edge surface limits supporter more in the middle part of wheel rim.Which quality of fit is high, and restraining ability is strong, but also has the following disadvantages: 1, commonality is not strong, and use cost is high.Use such supporter to need adapted custom wheel, namely there is in the middle part of rim for automobile wheel the annular recess coordinated with supporter.For high capacity vehicle, then must simultaneously more wheel change to change air-inflation tyre, high cost.2, difficulty is loaded and unloaded large.Determined by the fit system of supporter and wheel rim, the splicing of supporter and the assembling with wheel rim, must complete in inside tires simultaneously.Because heavy duty tire hardness is large, inside tires narrow space causes assembly manipulation very difficult.
Summary of the invention
For high capacity replacing vehicle pneumatic-tyred demand, take into full account the characteristic that high capacity Vehicle Speed is low.The invention provides a kind of structure simple, easy to loading and unloading, highly versatile, can use tubeless tires to provide the supporter of safety control for high capacity vehicle.
The technical scheme that the utility model adopts for its technical matters of solution is: inner tube-free wheel supporter, be made up of three support splits, locating dowel pin, contiguous blocks, supporting split is connected on wheel rim by locating dowel pin, contiguous block, support in split and arrange knock hole and interface, contiguous block is connected with support split by locating dowel pin.
Supporting split adopts aluminum alloy solid forging shaping, is made up of outer rim, inner edge, brace rod, reinforced rib, interface, connecting bore.Support split and be provided with the interface that can mutually be engaged, be convenient to realization and splice and combine.Screw thread fit on connecting bore negative thread and locating dowel pin, realizes supporting being connected and fixed of split and locating dowel pin.
Locating dowel pin is stepped shaft structure, and stage casing arranges screw thread and limited step, and screw thread cooperatively interacts with the screw thread supported in split knock hole, and limited step limits the degree of depth that locating dowel pin is screwed into knock hole.Corners process is carried out at locating dowel pin two ends, and is supported on tyre rim place, the displacement of fixed support body and prevent wearing and tearing tire inner cavity surface.
Interface guarantees that three support the requirement that split can meet all kinds wheel rim.
During installing wheel, the utility model can be sleeved on rim for automobile wheel after inside tires completes splicing, then is coordinated by wheel ectosome fixing with wheel endosome, reduces the difficulty of supporter assembling.
The beneficial effects of the utility model are, commonality is stronger, does not need adapted custom wheel, at the flat wheel of common three-member type, the flat wheel of opposite opened or opposite opened semi drop center rim(sdc) wheel all can be installed, and reduces the use cost of supporter.Can be sleeved on rim for automobile wheel after inside tires completes splicing, reduce supporter assembly difficulty.

Detailed description of the invention
As shown in Figure 1, inner tube-free wheel supporter, is made up of three support splits 6, locating dowel pin 4, contiguous blocks 5, supports split 6 and be connected on wheel rim by locating dowel pin 4, contiguous block 5, support in split 6 and arrange knock hole and interface, contiguous block 5 is connected with support split 6 by locating dowel pin 4.
Supporting split 6 adopts aluminum alloy solid forging shaping, is made up of outer rim, inner edge, brace rod, reinforced rib, interface, connecting bore.Support split 6 and be provided with the interface that can mutually be engaged, be convenient to realization and splice and combine.Connecting bore negative thread coordinates with the screw thread 42 on locating dowel pin 4, and realization support split 6 is connected and fixed with locating dowel pin 4
Connection between split is realized by locating dowel pin and contiguous block.Locating dowel pin 4 can coordinate the connection realizing point interblock with contiguous block, can limit again supporter, in wheel rim restriction, play occur.Locating dowel pin 4 is stepped shaft structure, and stage casing is processed with screw thread 42, limited step 41, and corners process is carried out at locating dowel pin 4 two ends, prevents wearing and tearing tire inner cavity surface.Screw thread 42 cooperatively interacts with the screw thread in supporter connecting bore.The degree of depth that is screwed into of locating dowel pin 4 is limited by the limited step 41 of threaded upper portion completely.On contiguous block 5, through hole coordinates with locating dowel pin 4, is enclosed within by contiguous block 5 in adjacent split on locating dowel pin, namely realizes the splicing supporting split 6.
During installing wheel, loaded from tire one end by the endosome of three-member type or divided wheel, supporter can be enclosed within the wheel rim of wheel endosome easily, then by wheel ectosome, coordinates fixing with wheel endosome, the installation of whole car wheel structure that has been exactly real.After installation, the two end supports of locating dowel pin is at tyre rim place, thus the displacement of fixed support body.
