Specific implementation mode
The utility model is further described with reference to specific embodiment,
As shown in Figure 1-Figure 3, a kind of plastics and metal composite electric vehicle or motorcycle drum brake wheel hub, including metal material
Wheel rim 1, be arranged the inside of wheel rim 1 spoke 2 and be molded over the brake rim 3 in 2 center of spoke, the brake rim 3 is at middle part
Axle mounting portion 4 is formed, quoit 6 is also equipped on brake rim 3；The spoke 2, brake rim 3 and axle mounting portion 4 use
Moulding compound (moulding compound of Partial Species is also referred to as fiberglass) or engineering plastics are integrally formed；The inside of the wheel rim 1 is arranged
There are several connection parts, the spoke 2 to be combined as a whole with connection part.
The spoke 2, brake rim 3 and axle mounting portion 4 are integrally formed, and are needed by disc punching press compared to traditional iron tyre,
Intermediate sleeve is processed, and the cumbersome technique such as brake rim forging and integral solder, cleaning, cost advantage is apparent, only needs compression molding
It settles at one go.
The quoit 6 is iron ring, iron ring peripheral distribution have several reinforce it is convex with 3 bonding tightness of the brake rim
Item 61,3 inner wall of the brake rim form annular convex platform 31, and annular convex platform 31 is for being fixedly mounted the quoit 6, raised line 61
Design so that in process moulding compound or engineering plastics can be molded along these raised lines, iron ring and brake rim 3 it
Between contact surface increase so that the combination of the two is more closely.
The center of the axle mounting portion 4 forms through hole 41 (as shown in Figure 4), and 41 both ends of through hole are both provided with axis
Mounting base 71,72 (as shown in Figure 3) is held, two bearing mounting bases are integrated or separately.Brake rim 3, axle mounting portion 4 and wheel
Spoke 2 is integrally formed, at low cost, extremely convenient.Avoid the process that traditional brake rim 3 separately forges manufacture.Two bearings
Substantially it is exactly sleeve in the prior art when mounting base 71,72 is an integral structure, is only molded in axle mounting portion 4
Molding is directly to be combined with sleeve, eliminates traditional welding sequence, reduces cost.Two bearing mounting bases 71,72 are point
When body, one section of metal tube material at middle part is further saved.
The circumference of the bearing mounting base 71,72 is both provided with the groove 73 of reinforcement and 4 bonding tightness of axle mounting portion.
The design of groove so that bearing mounting base 71,72 is combined more closely with axle mounting portion 4.
The groove circumnutates with one section or more of axially grooved 731 (as shown in Figure 6) or the groove 73 to be arranged in axis
It holds 71 surface of mounting base and forms the slot 732 (as shown in Figure 7) that circumnutates.It should be noted, in the process that electric vehicle or motorcycle are ridden
In, wheel rim 1 is subject to the critical piece of road shocks power and complete vehicle weight, when emergency stop, test that axle mounting portion 4 is actually born
Be distortion power, will produce the distortion power mutually deflected between axle mounting portion 4 and bearing mounting base 71,72, axially grooved 731 or
The design of slot 732 of circumnutating further has disperseed distortion power between axle mounting portion 3 and bearing mounting base 71,72, increases vehicle
Forced area and bond area between axis mounting portion 4 and bearing mounting base 71,72, improve the whole service life.
Articulated connection is：Plate 5 is welded on the inside of wheel rim, the spoke 2 coats plate 5 and is combined as a whole.
The design makes spoke 2 and wheel rim 1 combine closely, and convenient formation.
The surface forming of the plate 5 has a certain number of through-holes 51 (as illustrated in fig. 2 or fig. 5).2 compression molding of spoke
During, it can be with unicom 51 both sides of through-hole, it is ensured that the bonding tightness and fastness of plate 5 and spoke 2.
The moulding compound is SMC or PBT or BMC or PBT/PET mixtures；The wheel rim is iron ring.It has been observed that
During electric vehicle or motorcycle are ridden, wheel rim 1 is subject to the critical piece of road shocks power and complete vehicle weight, and moulding compound is real
The strength demand that wheel rim can be met on border, it is technically feasible that entire wheel hub is integrally formed using moulding compound.But
Applicant selects that iron ring is used to be integrally formed using moulding compound as wheel rim, spoke 2 and axle mounting portion 4, spoke while and wheel rim
The connection part of inside is combined closely, the reason is that：Iron ring can keep good heat dissipation effect, when summer high-temperature, iron
Circle 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 mistake
Crowbar must rely on wheel rim to be supported in journey, and the work of part tire changing personnel is more rough, therefore, applicant's selection
It sets wheel rim to iron ring and substantially solves tire internal temperature diverging, asking for wheel rim damage may be caused during tire changing
Topic.
The wheel rim 1 includes slot bottom 11, bcad seats 12 and wheel rim 13, and the bcad seats 12 is arranged outside two of slot bottom 11
Side, the wheel rim 13 are arranged in two outsides of bcad seats 12, and the wheel rim 13 is the structure of flanging or in-flanges；The slot
Bottom 11, bcad seats 12 and wheel rim 13 are an integral molding structure.The design enables wheel hub to be suitable for different demands.
The structure (as shown in Figure 8) of the in-flanges is：13 edge of the wheel rim is towards lateral bend in the bcad seats 12
Crimping 1, crimping 1 and the inside of bcad seats 12 are close, when tire is installed on the bcad seats of wheel rim 1, the rubber of tire
Glue material can be resisted against at crimping 1 and be formed the sealing to crimping, prevent extraneous dust or sewage silt into
Enter, the corrosion of less wheel rim keeps this wheel hub more durable.
The structure (as shown in Figure 9) of the flanging is：13 edge of the wheel rim is towards 12 outer lateral bend of the bcad seats
Crimping 2 16, crimping 2 16 and the outside of bcad seats 12 are close, and such crimping form works as wheel compared with the installation suitable for vacuum tire
When tire is installed on the bcad seats 12 of wheel rim 1, the inner rubber material of vacuum tire can be resisted against at crimping 2 16 and be formed
Sealing to tire prevents the entrance of extraneous dust or sewage silt, the corrosion of less wheel rim 1 from keeping this wheel hub more resistance to
With, while crimping 2 16 and bcad seats 12 are close to, crimping 2 16 is not susceptible to deform under pressure, improves the use of tire
Service life.
It should be understood by those skilled in the art that the present utility model is not limited to the above embodiments, above-described embodiment and
Only illustrate the principles of the present invention described in specification, on the premise of not departing from the spirit and scope of the utility model,
The utility model also has various changes and improvements, these changes and improvements both fall within claimed the scope of the utility model
It is interior.The protection scope of the present invention is defined by the appended claims and their equivalents.
