Description
Technical field
This utility model relates to wheel rim technical field, particularly to the carbon fiber opening wheel rim of a kind of outer ring tire lip oblique angle design.
Background technology
The carbon fibre rim of existing outer ring opening, its opening be designed with following two:
A kind of is the design of crisperding.This design is the design that comparison is traditional, is transformed by metal rim in early days.The design of crisperding is the design that a kind of comparison is safe from the use and theory of wheel rim, after tire installs, then inflate inside tire, when tire pressure reaches to a certain degree, the edge of tire can just snap into inside groove, in use, when leak air or blow out etc. situation time, tire will not be jumped out inside wheel rim.But this design is from the point of view of the design and procedure for producing management and control of carbon fiber product itself, the position of wheel rim crisperding carbon fiber design comparison bothers, and the bad management and control of quality preservation of production, product fraction defective is higher, improves the cost of finished product.Another due to the relation of crisperding moulding, the position that in Fig. 1, crisperding is drawn a circle is the region that wheel rim stress is maximum, and the when that or wheel rim too high at tire pressure being by serious impact, this position easily produces the phenomenon of wheel rim fracture.
Produce produced problem for crisperding, after be derived again the second design, the design of straight flange will be made by crisperding.For carbon fibre rim, the design of straight flange can improve crisperding very well and design produced problem aborning.Although it is the design of a safety, but some consumer may worry that tire can be jumped out from wheel rim in the case of gas leakage or blowing out.When wheel rim by than more serious impact time, the phenomenon (as drawn a circle shown in position in Fig. 2) that edge, outer ring is most susceptible to destroy and makes wheel rim occur splitting, so such design is not the most accepted by everyone.

Detailed description of the invention
Below in conjunction with the accompanying drawings with concrete preferred implementation, this utility model is described further.
As shown in Figure 4, a kind of carbon fiber opening wheel rim of outer ring tire lip oblique angle design, including wheel hub 1 and two outer ring tire lips 2, two outer ring tire lips 2 are stretched out by the two ends of wheel hub 1 and are formed, this outer ring tire lip 2 is outwards sequentially provided with portion 21 and an oblique portion 22 always from wheel hub 1 two ends, the oblique portion 22 of outer ring tire lip 2 tilts to the vertical axis direction of wheel hub 1, the cross-sectional width in this oblique portion 22 is stepped up to top by its bottom, the described two oblique portions 22 of outer ring tire lip 2 are arranged in "eight" shape, form an angle α with vertical direction inside the oblique portion 22 of described outer ring tire lip 2, preferably 0o<α≤30o。
As shown in Figure 4, wheel hub 1 can include that a placenta 11 and supports seat 12, and the two ends of placenta 11 are connected with the two ends of support seat 12, and two outer ring tire lips 2 are stretched out by the two ends of hub support seat 12 and formed, and wheel hub can also be other design structure.Placenta 11 be respectively arranged at the two ends with a platform 111, this platform 111 is symmetrical set with wheel hub 1 central symmetry axis, is provided with a smooth concave surface 112 in the middle of placenta 11, can be used for accommodating and supporting tire, and its surface can fit with the surface of tyre charging gas.
As it is shown on figure 3, the linear width of placenta platform 111 is L, it is preferably 1.5mm≤L≤5mm.Placenta platform 111 is H to the height on top, tire lip oblique portion 22, outer ring, and it is preferably 5.3mm≤H≤7mm.
The cross-sectional width on top, tire lip straight portion 21, outer ring is equal to the cross-sectional width of bottom, tire lip oblique portion 22, outer ring, the cross-sectional width L4 of bottom, tire lip oblique portion, outer ring is 2.0～4.0mm, the cross-sectional width L5 on its top is 2.5～5.0mm, cross-sectional width L4 such as this bottom, tire lip oblique portion, outer ring is designed as 3.5mm, when the cross-sectional width L5 on its top is designed as 4.0mm, now the cross-sectional width in the oblique portion of outer ring tire lip is bigger than the cross-sectional width of tire lip in Fig. 1 and Fig. 2 (as shown in Figures 1 and 2, L1=2.0mm, L2=3.5mm, L3=3.0mm), the impact resistance of wheel rim can be improved, and then improve its safety in utilization and service life.Additionally the oblique portion of outer ring tire lip 22 by bottom to top extend forms the first cambered surface 23, dispersible the stress suffered by wheel rim, do not have Fig. 1 crisperding design in stress concentration cause wheel rim to rupture problem, can further improve its safety in utilization and service life.
In addition, placenta platform 111 forms the second cambered surface 113 with the junction in the straight portion 21 of outer ring tire lip 2, placenta platform 111 and placenta smooth the junction of concave surface 112 and form the 3rd cambered surface 114, and this cambered surface can improve the impact resistance of wheel rim, and each cambered surface recited above is all smooth and continuous print.
In sum, opening wheel rim of the present utility model is after the design of the comprehensive crisperding in Tai Chun position, outer ring and straight flange, use the design that straight portion and oblique portion combine, in vertical direction with certain angle α inside this oblique portion, making two outer ring tire lips is that "eight" shape structure is arranged so that its quality is improved, and reduces production cost, improve safety in utilization and service life, it is easier to accepted by market.
Still further provides the manufacture method of this utility model opening wheel rim, its step is as follows:
(1) making the carbon fiber opening rim mould of a tire lip oblique angle design, then on pre-mould, carbon fibre initial rinse fabric is sticked according to the shape lamination of wheel rim, be placed into airbag, make pre-type product, this pre-type product size is more smaller than finished product after molding；
(2) pre-type product is put in wheel rim mould, be then placed in former, matched moulds, in molding airbag, fill gases at high pressure, 160 degree of molding 60 minutes；
(3) wheel rim of forming is removed from the molds；
(4) burr removing, takes out molding airbag, the flatness of inspection wheel rim and out of roundness；
