Abstract

The utility model discloses a kind of lightweight wheels, and including wheel rim and radial support in the spoke of wheel rim, the section line of the internal chamber wall of the spoke radially includes the curved section of evagination；Vehicle wheel spoke carries on the back chamber curve and uses arch design, when vehicle wheel spoke is when by external impact, can spring back mitigation and impact, and in the case where not increasing spoke thickness, the hardly change angle moulding face R, fully meets impact strength needed for wheel design；Conducive to the light-weighted purpose of wheel is realized, vehicle oil consumption, energy-saving and emission-reduction are reduced.

Description

Lightweight wheel

Technical field

The utility model relates to art of wheels, and in particular to a kind of lightweight wheel.

Background technique

As automobile fuel consumption is taken seriously further, at present in Automobile Design, light-weight design increasingly receives an acclaim.But In Designing Aluminum-Alloy Wheels, to meet wheel impacts intensity, wheel light-weight design popularity is not high；To meet impact Intensity, increases the angle R of the outer moulding of aluminum-alloy wheel, or increases spoke thickness (or width), still, spoke thickness increase (or it is wide Degree increases), wheel mass increases therewith, while wasting aluminum alloy materials, increases complete vehicle quality, vehicle oil consumption is caused to increase Greatly.In addition, if increasing the angle moulding face R wheel moulding will be changed, or be unable to satisfy original design intention.

Therefore, in order to solve the above problem, need a kind of lightweight wheel, can satisfy production technology, guarantee wheel strength, The requirement for not changing wheel moulding simultaneously, is conducive to realize the light-weighted purpose of wheel, reduces vehicle oil consumption, energy-saving and emission-reduction.

Utility model content

In view of this, providing lightweight wheel, Neng Gouman the purpose of the utility model is to overcome defect in the prior art Sufficient production technology guarantees wheel strength, the requirement for not changing wheel moulding simultaneously, is conducive to realize the light-weighted purpose of wheel, drop Low vehicle oil consumption, energy-saving and emission-reduction.

The lightweight wheel of the utility model, including wheel rim and radial support in the spoke of wheel rim, the inner cavity of the spoke The section line of wall radially includes the curved section of evagination.

Further, the internal chamber wall of the spoke radially section line include radially inner and outer distribution curved section and skew lines Section.

Further, the section line interlude is prominent axially outward forms outer concave segment.

Further, the outer concave segment and section line seamlessly transit.

Further, the inside of the spoke and wheel rim junction forms inner groovy.

Further, the inner groovy is prepared by drawing material treatment process.

Further, the inner groovy is U-lag, and the base angle of the U-lag is arc chord angle.

Further, the centre of the spoke is provided with centre bore, the interlude of the centre bore radially concave shape At loss of weight annular groove.

The beneficial effects of the utility model are: a kind of lightweight wheel disclosed by the utility model, it is bent that vehicle wheel spoke carries on the back chamber Line uses arch design, when vehicle wheel spoke is when by external impact, can spring back to mitigate and impact, and is not increasing spoke thickness, several In the case where not changing the moulding face angle R, impact strength needed for wheel design is fully met；It is light-weighted conducive to realization wheel Purpose reduces vehicle oil consumption, energy-saving and emission-reduction.

Detailed description of the invention

The utility model is further described with reference to the accompanying drawings and examples:

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Fig. 1 is the structural schematic diagram of the utility model, as shown, the lightweight wheel in the present embodiment, including wheel rim With radial support in the spoke 2 of wheel rim 1, the section line of the internal chamber wall of the spoke 2 radially includes the curved section 3 of evagination；Vehicle 2 back chamber curves of spoke use arch design (camber line), when wheel spoke 2 when by external impact, can spring backs to mitigate and impact, In the case where not increasing spoke thickness, hardly changing the angle moulding face R, impact strength needed for wheel design is fully met； Laterally indicate the left and right directions of car, it is longitudinal to indicate front-rear direction, inwardly indicate transversely to be directed toward car side, on the contrary for Outside.

In the present embodiment, the internal chamber wall of the spoke 2 radially section line include radially inner and outer distribution curved section 3 and tiltedly Straightway 4；The section line interlude is prominent axially outward to form outer concave segment 5；The outer concave segment 5 and section line are smoothed It crosses；Conducive to improvement radial elastic coefficient and rigidity, while stress being avoided to concentrate, 2 radial support intensity of wheel spoke is improved, into one Step improves impact strength；Structure is simple, easy to process.

In the present embodiment, the spoke 2 and the inside of 1 junction of wheel rim form inner groovy 6；The inner groovy 6 is by drawing Material treatment process is prepared；The inner groovy 6 is U-lag, and the base angle of the U-lag is arc chord angle, and stress is avoided to concentrate and open It splits, guarantees long service life, it is highly-safe；Under the premise of guaranteeing that tyre bead sits intensity (thickness), the connection of 2 wheel rim 1 of spoke is reduced The aluminium material at place, can maximum possible loss of weight, and increase moulding stereovision.

In the present embodiment, the centre of the spoke 2 is provided with centre bore 7, and the interlude of the centre bore 7 is radially Recess forms loss of weight annular groove 8；Wheel center hole 7 uses not isometrical design.To meet, (it is fixed to guarantee with brake boss assembly relation Position), need to be a bit of at close wheel mounting flange face end, it is assembly diameter (i.e. 7 diameter of centre bore) by its aperture design.Its The position of remaining no matching relationship, under the premise of not influencing wheel strength, maximization design is done in aperture.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
