Abstract
The utility model provides a kind of improved reverse rim structure of cast aluminum alloy wheel, including inner rim, 5 ° of inclined-planes of inboard tire bead seat, the big inclined-plane of inboard tire bead seat, bottom land, outboard tire bead seat and outer rim.Described reverse wheel rim inner rim inner thickness L1 is 12 14mm, 5 ° of ramp thickness L2 of inboard tire bead seat are 6.5 7mm, the big ramp thickness L3 of inboard tire bead seat is 6.5 7mm, the big inclined-plane of inboard tire bead seat and horizontal direction angle A are 40 ° 45 °, fillet R1 radiuses are R25 R35mm on the outside of the big inclined-plane of inboard tire bead seat, and the big chamfered inside radius of corner R2 of inboard tire bead seat is R10 R15mm, and thickness of groove bottom L4 is 6.5 7mm, outboard tire bead seat thickness L5 is 6 7mm, and foreign steamer edge thickness L6 is 12 14mm.The reverse rim structure, can strengthen the bearing capacity and impact resistance of the reverse wheel rim of cast aluminum alloy wheel.
Description
Technical field
The utility model belongs to cast aluminum alloy wheel field, and in particular to a kind of improved cast aluminum alloy wheel is reverse
Rim structure.
Background technology
Currently, the moulding process of aluminum-alloy wheel is main based on gravitational casting, low pressure casting and forging.Wherein, with casting
The aluminum-alloy wheel of method production is made, any space curved surface and shape can be made to coordinate different vehicles, different visitors are catered to
The demand at family.Therefore, cast aluminum alloy wheel is the wheel being had the call on current domestic and international market.Cast aluminum alloy wheel
Wheel rim have two kinds of structures of positive wheel rim and reverse wheel rim.Positive wheel rim is used primarily in car wheel and bearing capacity is relatively small
Wheel on, reverse wheel rim is used primarily in offroad vehicle wheel, picking-up vehicle wheel, freight car wheel etc. and the larger car of bearing capacity ratio
On wheel.
The three big experiments that aluminum-alloy wheel is often done are 13 ° of impacts, bending and Radial test.With the quick hair of automobile market
Exhibition and the constantly improve of professional standard, the demand of automobile vendor and after market can not be met by only doing three big experiments.Especially
It is that some are carried than larger automobile, and used is mostly the cast aluminum alloy wheel of reverse rim structure, and wheel rim is held
Loading capability and shock resistance require high, and three big experiments can not verify the bearing capacity of its wheel rim.Nearly 2 years, in the market
Some cast aluminum alloy wheels are constantly fed back, the wheel of especially reverse rim structure has wheel rim cracking phenomena in use
Occur.Therefore, clients require that aluminum-alloy wheel manufacturer increases by 90 ° of impact tests of wheel rim on the basis of three big experiments,
Preferably to examine the bearing capacity and impact resistance of wheel rim.Either cast aluminum alloy wheel industry mark both domestic and external
Standard, or specific requirement of each aluminum-alloy wheel manufacture commercial city to the reverse rim structure of cast aluminum alloy wheel be not same
Standard, accordingly, it would be desirable to carry out some improvement to the reverse rim structure of cast aluminum alloy wheel, in order to improve its intensity and
Shock proof ability.
Utility model content
The utility model is in order to improve the bearing capacity and impact resistance of the reverse wheel rim of cast aluminum alloy wheel, by multiple
Verification experimental verification there is provided a kind of improved reverse rim structure of cast aluminum alloy wheel.
To achieve the above object, the technical solution of the utility model is as follows：A kind of improved cast aluminum alloy wheel is reverse
Rim structure, including inner rim, 5 ° of inclined-planes of inboard tire bead seat, the big inclined-plane of inboard tire bead seat, bottom land, outboard tire bead seat and foreign steamer
Edge.Described reverse wheel rim inner rim inner thickness L1 is 12-14mm, and 5 ° of ramp thickness L2 of inboard tire bead seat are 6.5-7mm, interior
Bcad seats big ramp thickness L3 in side is 6.5-7mm, and the big inclined-plane of inboard tire bead seat and horizontal direction angle A are 40 ° -45 °, inner side tire
Fillet R1 radiuses are R25-R35mm on the outside of the big inclined-plane of ring support, and the big chamfered inside radius of corner R2 of inboard tire bead seat is R10-
R15mm, thickness of groove bottom L4 are 6.5-7mm, and outboard tire bead seat thickness L5 is 6-7mm, and foreign steamer edge thickness L6 is 12-14mm.
Brief description of the drawings
Fig. 1 is a kind of improved reverse wheel rim structural representation of cast aluminum alloy wheel.
Fig. 2 is a kind of size marking figure of the improved reverse rim structure of cast aluminum alloy wheel.
In figure：Tyre bead on the outside of 1- inner rims, 5 ° of inclined-planes of 2- inboard tire bead seats, the big inclined-plane of 3- inboard tire bead seats, 4- bottom lands, 5-
Seat, 6- outer rims.
Embodiment
Embodiment is described in detail below in conjunction with accompanying drawing.
A kind of reverse rim structure of improved cast aluminum alloy wheel, including it is inner rim 1,5 ° of inclined-planes 2 of inboard tire bead seat, interior
The big inclined-plane 3 of side bcad seats, bottom land 4, outboard tire bead seat 5 and outer rim 6.In order to improve its bearing capacity and impact resistance, institute
The reverse wheel rim inner rim inner thickness L1 stated is 12-14mm, and 5 ° of ramp thickness L2 of inboard tire bead seat are 6.5-7mm, inner side tire
The big ramp thickness L3 of ring support is 6.5-7mm, and the big inclined-plane of inboard tire bead seat and horizontal direction angle A are 40 ° -45 °, inboard tire bead seat
Fillet R1 radiuses are R25-R35mm on the outside of big inclined-plane, and the big chamfered inside radius of corner R2 of inboard tire bead seat is R10-R15mm, groove
