The utility model content
The purpose of the utility model provides a kind of easy to assembly, the hub assembly that can easily brake disc be pulled down.
The hub assembly of the utility model; Comprise brake disc, hub-bearing unit and wheel hub; The centre of said brake disc is provided with tri-angle-holed; Said brake disc is assembled together through said tri-angle-holed and said wheel hub, and the profile phase of the cross-sectional plane of said tri-angle-holed shape and said hub-bearing unit adapts to, so that said hub-bearing unit passes tri-angle-holed from said.
Preferably, said tri-angle-holed be equilateral triangle.
Preferably; Saidly tri-angle-holedly join end to end successively and form by the first identical inwall of length, second inwall, the 3rd inwall; The stage casing of said first inwall comprises first circular arc wall, and the stage casing of said second inwall comprises second circular arc wall, and the stage casing of said the 3rd inwall comprises the three-arc wall; Said first circular arc wall, said second circular arc wall, said three-arc wall respectively with the outer circle wall of said wheel hub on circular arc wall adapt, with to said brake disc radial location.
Preferably; Said first inwall is connected through first arc section with said second inwall; Said second inwall is connected through second arc section with said the 3rd inwall; Said the 3rd inwall is connected through the three-arc section with said first inwall, and said first arc section, said second arc section, said three-arc section adapt with the outer circle wall of said hub-bearing unit respectively, so that said hub-bearing unit passes tri-angle-holed from said.
The beneficial effect of the hub assembly of the utility model is: compact overall structure efficiently solves the narrow and small difficult problem of brake clamp arrangement space; The centre of the brake disc of the hub assembly of the utility model is provided with the profile hole that the profile phase with the cross-sectional plane of hub-bearing unit adapts to; Make that assembling is convenient; Can easily brake disc be pulled down simultaneously convenient maintenance, replacing to brake disc; Alleviate product and complete vehicle weight, helped the energy-saving and emission-reduction of vehicle.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Like Fig. 1, shown in Figure 2, the hub assembly of the utility model comprises brake disc 1, hub-bearing unit 2, wheel hub 3 and tire bolt 4.
In conjunction with Fig. 3, shown in Figure 4; The centre of brake disc 1 is provided with profile hole 5; Brake disc 1 is assembled together through profile hole 5 and wheel hub 3, and the profile phase of the cross-sectional plane of the shape of profile hole 5 and hub-bearing unit 2 adapts to, so that hub-bearing unit 2 passes from profile hole 5.
The centre of the brake disc 1 of the hub assembly of the utility model is provided with the profile hole 5 that the profile phase with the cross-sectional plane of hub-bearing unit 2 adapts to, and makes that assembling is convenient, can easily brake disc be pulled down convenient maintenance to brake disc simultaneously.
In the present embodiment, the profile of the cross-sectional plane of hub-bearing unit 2 is a triangle, and the shape of the profile hole 5 that adapts with it also is triangle.
In the present embodiment, the profile of the cross-sectional plane of hub-bearing unit 2 is an equilateral triangle, and profile hole 5 also is an equilateral triangle.
Particularly; Profile hole 5 is joined end to end successively and is formed by the first identical inwall 51 of length, second inwall 52, the 3rd inwall 53; The stage casing of first inwall 51 comprises that the stage casing of first circular arc wall, 61, the second inwalls 52 comprises that the stage casing of second circular arc wall, 62, the three inwalls 53 comprises three-arc wall 63; First circular arc, 61 walls, second circular arc wall 62, three-arc wall 63 respectively with the outer circle wall of wheel hub 3 on circular arc wall adapt, with to brake disc 1 radial location.
In the present embodiment; First inwall 51 is connected through first arc section 71 with second inwall 52; Second inwall 52 is connected through second arc section 72 with the 3rd inwall 53; The 3rd inwall 53 is connected through three-arc section 73 with first inwall 51; First arc section 71, second arc section 72, three-arc section 73 adapt with the outer circle wall of hub-bearing unit 2 respectively, and promptly first arc section 71, second arc section 72, three-arc section 73 adapt with the arc section of the outer circle wall of hub-bearing unit 2 respectively, so that hub-bearing unit 2 passes from profile hole 5.
When the hub assembly to the utility model assembles, at first can be with hub-bearing unit 2 and wheel hub 3 assemblings; Then six tires bolts 4 are loaded on the wheel hub 3; At last, brake disc 1 overlapped hub-bearing unit 2 (being that hub-bearing unit 2 passes) from profile hole 5 after, be loaded on wheel hub 3 inboards.
When needs maintenance brake disc 1, can easily brake disc 1 be disassembled from wheel hub 3 inboards, take off from hub-bearing unit 2 these sides (being that hub-bearing unit 2 passes the back from profile hole 5) then.
The hub assembly of the utility model is compared with traditional hub assembly, has compact conformation, simple, saves arrangement space, is easy to assembling, saves cost, and is of value to advantage such as automobile energy-saving reduction of discharging.
The beneficial effect of the hub assembly of the utility model is: owing to adopt the outside of brake disc to be loaded on the inboard of wheel hub, compact overall structure efficiently solves the narrow and small difficult problem of brake clamp arrangement space; The centre of the brake disc of the hub assembly of the utility model is provided with the profile hole that the profile phase with the cross-sectional plane of hub-bearing unit adapts to; Make that assembling is convenient; Can easily brake disc be pulled down simultaneously convenient maintenance, replacing to brake disc; Alleviate product and complete vehicle weight, helped the energy-saving and emission-reduction of vehicle.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
