Abstract

The invention discloses a wheel spoke, which comprises a cylindrical part, an installation part and a connecting part, wherein the cylindrical part is molded by using steel plates; the installation part is provided with bolt holes which are uniformly distributed on the periphery of a central through hole; the connecting part is positioned between the cylindrical part and the installation part; the connecting part is provided with a plurality of cooling air holes distributed by taking the central through hole as the center; and at least one circle of projecting parts which take the central through hole as the circle center and are opposite to the opening of the cylindrical part are arranged in a ring defined by the cooling air holes. Compared with the prior art, the wheel spoke has the advantage that high spoke strength can be achieved by adopting thin spoke steel plates, so that light weight of the wheel spoke is realized.

Description

Wheel spoke

Technical field

The present invention relates to motor vehicle components manufacturing technology field, especially a kind of spoke of automobile-use wheel.

Background technology

For realizing energy-saving and emission-reduction, reduce the energy, raw materials consumption, the vehicle lightweight is development tendency.Reducing spoke weight is effective ways that alleviate wheel weight, but wheel is the support part of whole vehicle, wheel in the process of moving with dynamic load large and complicated, and spoke is the main stressed member of wheel bearing load, very high to its requirement of strength, if reduce simply the force intensity that is subjected to that spoke thickness will reduce spoke, reduce the travel safety of self-propelled vehicle, therefore, alleviating between the weight of spoke and the intensity that the people holds spoke is conflict, and how obtaining lighter spoke and keeping the intensity of enough spokes is the target that people pursue always.

Summary of the invention

Problem to be solved by this invention provides a kind of wheel spoke, can adopt thinner spoke plate and obtains preferably Spoke Strength.

In order to solve the above-mentioned problem of stating, the technical solution used in the present invention is: this wheel spoke includes the barrel with steel plate forming, installation portion with the bolt hole that is evenly distributed on the central through hole periphery, and the connecting portion between described cylindrical part and described installation portion, be provided with a plurality of cooling airs hole that centered by described central through hole, distributes at described connecting portion, in the ring that described cooling air hole surrounds, be provided with at least a ring take described central through hole as the center of circle and described barrel opening bossing towards the opposite.

In the technique scheme, can also be more specifically: a side of bossing be curved sides at least, and the bending direction of this curved sides is opposite with the bending direction at described bossing top;

Further: the end face that described bossing protrudes is arcwall face, and the recessed bottom surface of described curved sides is arcwall face;

Further: the end face that described bossing protrudes is the plane, and the recessed bottom surface of described curved sides is the plane.

Further: the end face that described bossing protrudes can be 12 ~ 15 millimeters with the minimum value of the curvature of a curve radius of the Plane intersects of crossing described central through hole axis, and the bottom surface that the side of described bending is recessed into can be 10 ~ 13 millimeters with the minimum value of the curvature of a curve radius of the Plane intersects of crossing described central through hole axis.

Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:

Certain type same specification wheel of producing take the applicant is as example, and prior art spoke plate thickness is that 4 millimeters weight are 3.16 kilograms; Adopting the spoke plate thickness of technique scheme is 3.8 millimeters, and weight is 2.84 kilograms; The intensity ratio prior art of the wheel made from technique scheme improves about 10%.

Fig. 2 is that Fig. 1 is along the cutaway view of G-G direction.

Fig. 3 is the partial enlarged drawing at H place among Fig. 2.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing embodiment:

Fig. 1, Fig. 2 and wheel spoke shown in Figure 3 have the barrel with steel plate forming, namely such as the bottom among Fig. 2, installation portion, it is the core that having among Fig. 1 is evenly distributed on peripheral 4 bolts hole of central through hole, and the connecting portion between cylindrical part and installation portion, be provided with 14 cooling air holes of well-distributed centered by central through hole at connecting portion, the ring that surrounds in 14 cooling air holes is provided with a ring take central through hole as the center of circle and barrel opening bossing towards the opposite with interior.The inner side edge of the napex 4 of bossing partly is straight flange 3, and the outer side edges of the napex 4 of bossing partly is curved sides 5, and the bending direction of curved sides 5 is opposite with the bending direction at the top of bossing 4.The end face that bossing napex 4 protrudes is arcwall face, and this end face is 12 millimeters with the minimum value of the curvature of a curve radius of the Plane intersects of crossing the central through hole axis; Curved sides 5 recessed bottom surfaces are arcwall faces, and this bottom surface is 10 millimeters with the minimum value of the curvature of a curve radius of the Plane intersects of crossing the central through hole axis.

Among second embodiment of this wheel spoke, when the end face that bossing napex 4 protrudes is arcwall face, this end face is 15 millimeters with the minimum value of the curvature of a curve radius of the Plane intersects of crossing the central through hole axis, when curved sides 5 recessed bottom surfaces are arcwall face, this bottom surface is 13 millimeters with the minimum value of the curvature of a curve radius of the Plane intersects of crossing the central through hole axis, and other parts are extremely embodiment illustrated in fig. 3 identical with Fig. 1.

Among the 3rd embodiment of this wheel spoke, the end face that bossing protrudes is the plane; The bossing outer side edges is curved sides, and the recessed bottom surface of this curved sides is the plane, and other parts are extremely embodiment illustrated in fig. 3 identical with Fig. 1.
