Specific implementation mode
The utility model is further described with reference to specific embodiment, referring to Fig. 1-Figure 15：
Embodiment 1, as shown in figures 1-8, a kind of novel electric vehicle or motorcycle disc-brake wheel hub, including wheel rim 1, setting exist
Axle mounting portion 19 in spoke center, the left side of the axle mounting portion 19 and 2 knot of spoke is arranged in the spoke 2 of the inside of wheel rim 1
It closes, the right side of axle mounting portion 19 forms disc brake mounting base 3, and the center of axle mounting portion 19 is provided with passing through for installation axle 16
The both ends of through-hole 15, through hole 15 are both provided with bearing fixed seat 6,7；Spoke 2 and axle mounting portion 19 use moulding compound or work
Engineering plastics are integrally formed.Integrally formed mode is compared traditional iron tyre and is needed by disc punching press, intermediate sleeve processing, disc brake peace
The cumbersome techniques such as seat forging and integral solder, cleaning are filled, cost advantage is apparent, only compression molding is needed to settle at one go.
The disc brake mounting base 3 is：The right end of axle mounting portion 19 is embedded, and there are three above screw-jointing seat 5,5 edges of screw-jointing seat
Circumferentially, 5 center of screw-jointing seat is provided with internal thread hole to the axis of bearing mounting hole, and screw-jointing seat 5 is also in axle mounting portion 19
It is embedded in advance during compression molding, it is easy for installation.
The bearing fixed seat 19 can be directly by moulding compound one compression molding, alternatively, bearing fixed seat is to be inlaid in
Insertion in axle mounting portion 19；Wherein, bearing fixed seat is that the design of insertion can be divided into two kinds again：(1) axle is installed
The bearing fixed seat at 19 left and right both ends of portion is two independent individual (as shown in Figure 4), when the bearing fixed seat at left and right both ends
For two it is independent individual when, can save middle part one end metal tube material, save material to reduce production cost,
But mould structure is increasingly complex；(2) bearing fixed seat at 19 left and right both ends of axle mounting portion extend towards be combined into one it is complete
Whole sleeve (component in such as Fig. 9 marked as 23), being provided in the middle part of sleeve prevents axially displaced annular groove 22, axle installation
Portion is directly joined integrally with sleeve, eliminates the welding sequence of traditional handicraft, can also reduce production cost.
Three kinds of design methods of bearing fixed seat are required to lathe secondary process, are expanded in bearing fixed seat center by lathe
Hole machined, refine go out bearing mounting hole 17, bearing 18 can be installed in bearing mounting hole 17.Bearing mounting hole 17 needs and wheel rim
1 outer ring is arranged concentrically, so that it is guaranteed that tire will not beat.In the present embodiment, the bearing at 19 left and right both ends of axle mounting portion is fixed
Seat 6,7 is two independent individuals.
The middle part of the disc brake mounting base 3 is provided with positioning convex platform 4, and the week surrounded in screw-jointing seat 5 is arranged in positioning convex platform 4
In line region.

In capable process, wheel rim 1 is subject to the critical piece of road shocks power and complete vehicle weight, and when emergency stop, axle mounting portion 19 is practical
The test born is distortion power, and the distortion power mutually deflected is will produce between axle mounting portion 19 and bearing mounting base 6,7, axial
The design of fluting 101 or the slot 102 that circumnutates further has disperseed the distortion power between axle mounting portion 19 and bearing mounting base 6,7,
The forced area and bond area between axle mounting portion 19 and bearing mounting base 6,7 are increased, the whole service life is improved.
The moulding compound is that (i.e. sheet molding compound, primary raw material are added SMC by SMC special yarns, 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, be a kind of semidry method manufacture glass-fiber reinforced thermo-setting product molding in
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 is molded) or PBT/PET mixtures；
The present embodiment selects SMC.
The wheel rim is iron ring, and the connection part 24 on the inside of wheel rim is the plate 12 of welding, and the spoke 2 coats plate
And be combined as a whole, the design of plate 12 can make the combination of spoke 2 and wheel rim 1 even closer, and convenient for molding.As before
It states, during electric vehicle or motorcycle are ridden, wheel rim 1 is subject to the critical piece of road shocks power and complete vehicle weight, mould
Plastics can essentially meet the strength demand of wheel rim, and it is technically feasible that entire wheel hub is integrally formed using moulding compound
's.
There are one above through-hole 13 or more than one inner fovea parts for the surface forming of the plate 12.The spoke 2
Cladding plate is simultaneously combined as a whole, can be with 13 both sides of unicom through-hole, it is ensured that plate 12 during 2 compression molding of spoke
With the bonding tightness and fastness of spoke 2.
The edge of the wheel rim 1 is in-flanges 9 or flanging, and in the present embodiment, 9 fold inward of in-flanges is to close to wheel rim
Shoulder so that intensity is more preferable, is more bonded tire, more attractive.
Applicant selects that iron ring is used to be integrally formed using moulding compound as wheel rim, spoke 2 and axle mounting portion 19, and spoke is same
When and wheel rim on the inside of connection part combine closely, iron ring can keep good heat dissipation effect, when summer high-temperature, iron ring
It can be good at coming out the conduct heat away of inside tires, it is ensured that the service life of tire.In view of later stage tire changing process
Middle crowbar must rely on wheel rim to be supported, and the work of part tire changing personnel is more rough, and therefore, applicant selects will
Wheel rim is set as iron ring and substantially solves tire internal temperature diverging, the technology that wheel rim may be caused to damage during tire changing
Problem.
