Specific embodiment

The utility model is further described combined with specific embodiments below:

As shown in figs 1-9, a kind of modified disc brake hub, including wheel rim 1, the spoke 5 that 1 inside of wheel rim is arranged in, setting Metal axle sleeve 4 in 5 center of spoke, which is characterized in that one end of the axle sleeve 4 stretches out spoke and is equipped with disc brake mounting base 3, The spoke 5 is integrally formed using moulding compound or engineering plastics, and the outside at 4 middle part of axle sleeve is provided with reinforcer 9, reinforcer It is combined as a whole in 9 insertion spokes 5 and with spoke.Axle sleeve and disc brake mounting base are conventional fittings；When brake, axle sleeve is main Stressed member, axle sleeve use metalwork, and new material spoke is combined in the case where possessing intensity, is connect to old spare and accessory parts It closes, reduces the difficulty of wheel hub enterprise technology upgrading.

The reinforcer 9 is the more than one metal supporting rings 91,92 being welded on axle sleeve 4.

The anchor ring or outer edge of the metal supporting rings are disposed with several caulking grooves 93.

The oblique external expansion of anchor ring of the metal supporting rings 91,92.Reinforcer selects metal supporting rings and metal supporting rings Anchor ring tiltedly abducent design so that the twisting resistance of spoke enhances, the metal supporting rings of inclined design are than planar metal branch Pushing out ring is more resistant against axial force and radially outward force.

There are two the metal supporting rings 91,92 are set side by side, the anchor ring of two metal supporting rings 91,92 gradually draw close to Certain distance.The distance is with two 91,92 trisection spokes of metal supporting rings with a thickness of best.

The edge of the wheel rim 1 is in-flanges 7, and the design of in-flanges is so that edge of rim intensity is more preferable, not vulnerable to collision Deformation.

Setting is there are three flange portion 31 around the disc brake mounting base 3, is provided with counterbore 6 in flange portion, flange portion to Spoke side extends to form thickening part 61, and the counterbore 6 runs through thickening part 61, and flange portion extends to form thickening to spoke side Portion, the counterbore run through thickening part, the design so that counterbore has bigger depth so as to be screwed into bolt have enough locking Intensity.

The outside of the spoke 5 is provided with connector 8, and spoke 5 coats inner end or the spoke and described of the connector 8 The inner end bolt 10 of fitting 8 connects；The specific structure of the connector 8 is: the outer end of a metal sheet 84 is first turned over downwards shape At the first bending part 83,83 outer end of the first bending part flips up to form the second bending part 81 again, the first bending part 83 and second The combination of bending part 81 forms U-shaped main body 85；The middle part of the inner end insertion spoke 2 of metal sheet 84 is simultaneously combined as a whole with spoke, U The outside of type main body and 1 inner wall of wheel rim weld.In the insertion spoke that the connector of the utility model can be more placed in the middle, and It will not there are biggish gaps between spoke and wheel rim；Moreover, the welding position between connector and wheel rim is directly exposed to take turns Spoke facilitates weld job, also facilitates quality examination.

Preferably, the spoke 2 is that moulding compound or engineering plastics are integrally formed.

Preferably, the spoke thickness d1, d2 of 84 two sides of metal sheet are essentially identical.So that spoke cladding connector is simultaneously Integrally formed intensity is more preferable.

Preferably, the middle part convex of the U-shaped main body 85 and it is bonded wheel rim inner wall.

Preferably, the metal sheet 84 with a thickness of 1.6~2.2mm, the thickness of metal sheet 84 cannot be blocked up, otherwise It is not easy punching press, can not be excessively thin, otherwise weld strength is not up to standard.In the thickness range, by the weld part of wheel rim and plate The outside 82 at U-shaped main bent part is arranged in position, i.e., the outside 82 and wheel rim inner wall at U-shaped main bent part are welded, which fills Divide the advantage bigger using bending part thickness, so that weld strength is beyond the attainable limit of 84 thickness of unitary piece of metal sheet material institute.

Preferably, the opening 87 of the U-shaped main body is provided with more than one pad 851, and pad 851 is being opened 87 are welded as a whole the first bending part 83 and the second bending part 81 at mouthful.The design is not so that connector will receive wheel hub radial direction Power influences, and stability is more preferable.As shown in fig. 7, when spoke and wheel rim are tended to separate out by external force, the design of pad 851 The deformation so that connector 8 will not be stretched, it is ensured that the intensity of wheel hub structure.

Preferably, the pad 851 extends to form welding section along the length direction of U-shaped main body.

Preferably, the middle part or edge of the metal sheet 84 are provided with several through slots 86.

The moulding compound is that (i.e. sheet molding compound, primary raw material are added SMC by SMC special yarn, unsaturated-resin, lower shrinkage Add agent, filler and various auxiliary agents composition) or PBT (i.e. polybutylene terephthalate (PBT) is terephthalic acid (TPA) and Isosorbide-5-Nitrae-fourth two The condensation polymer of alcohol) or BMC (i.e. tubular molding compound is in a kind of molding of semidry method manufacture glass-fiber reinforced thermo-setting product Between material, it is mixed in advance by unsaturated polyester resin, lower shrinkage/low-contour additive, initiator, inner pattern releasing agent applicable, mineral filler etc. Paste is synthesized, thickener, colorant etc. are added, the glass fibre with different length is stirred in dedicated material kettle, into Row thickening ultimately forms the intermediary material of bulk, can be used for being molded and being molded) or PBT/PET mixture；

The present embodiment selects SMC.
