Description

A kind of 15 ° of DC rim for automobile wheel

Technical field

The utility model relates to a kind of 15 ° of DC rim for automobile wheel.

Background technique

Wheel generally includes tire, wheel rim, spoke and wheel hub, and tire is mounted on wheel rim, and wheel hub is used to connect with axle, The effect of spoke is then connection wheel rim and wheel hub.

Traditional wheel is wheel rim and spoke Combination Welding, and spoke is spinning reduction process, wheel rim after rolling forming, Base material is slightly thinned, and Reducing thickness is between 5%-15%, and after tyre inflating installation, under effect loaded, especially vehicle exists It is travelled compared with up-and-down surfaced road, two side flange of wheel rim and 15 ° of inclined-planes (i.e. bcad seats) are easy due to discontinuity, wheel rim base material are thinned Cause intensity insufficient, thus deformation failure.

Utility model content

The utility model provides a kind of 15 ° of DC rim for automobile wheel, and which overcome the prior arts described in background technology It is insufficient.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of 15 ° of DC rim for automobile wheel, including being located at the deep trouth of wheel rim axial centre, inclined positioned at 15 ° of deep trouth two sides Bcad seats and positioned at wheel rim axial ends and the wheel rim that is connected with bcad seats, which corresponds to bcad seats, wheel rim and tyre bead The junction position of seat and wheel rim is equipped with a plurality of convex ribs, those convex ribs extend along the axis direction of wheel rim, and those convex ribs edges Wheel rim inner face circumferential direction uniform intervals are laid.

Among one embodiment: those convex ribs extend to the axial end face of wheel rim and the intersection of wheel rim inner face from bcad seats Place.

Among one embodiment: those convex ribs extend the width and bcad seats of the width, entire wheel rim that are related to entire bcad seats With the junction of wheel rim.

Among one embodiment: the convex ribs are 15-50mm along the development length of wheel rim axial direction.

Among one embodiment: the width of the convex ribs is 3-20mm.

Among one embodiment: the height of the convex ribs is 0.5-2.0mm.

Among one embodiment: the convex ribs are 40mm along the development length of wheel rim axial direction.

Among one embodiment: the width of the convex ribs is 12mm.

Among one embodiment: the height of the convex ribs is 1.2mm.

The technical program compared with the background art, it has the following advantages:

The wheel rim is equipped with the convex ribs of circumferentially-spaced laying in the bcad seats of inner face, wheel rim and their junction, solves Deficiency existing for above-mentioned background technique tradition wheel rim enhances the intensity at the main force part bcad seats of wheel rim, that is, strengthens Wheel rim does not easily cause and occurs in the case where vehicle heavy duty with the wheel rim position at tire interface to the endurance of lateral force Discontinuity and the phenomenon that deformation failure, while also increasing the stability of tire running, increase the weight that vehicle can carry Amount, extends the service life of wheel rim.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and examples.

Fig. 1 depicts a kind of schematic front view of 15 ° of DC wheels.

Fig. 2 depicts a kind of left view schematic diagram of 15 ° of DC wheels.

Fig. 3 depicts a kind of schematic three dimensional views of 15 ° of DC wheels.

Specific embodiment

Please refer to Fig. 1 to Fig. 3, a kind of 15 ° of DC rim for automobile wheel, including being located at the deep trouth 11 of wheel rim axial centre, being located at deeply The inclined bcad seats 12 of 15 ° of 11 two sides of slot and in wheel rim axial ends and the wheel rim 13 that is connected with bcad seats, the wheel rim Face corresponds to bcad seats 12, wheel rim 13 and bcad seats 12 and the junction position of wheel rim 13 is equipped with a plurality of convex ribs 10, those convex ribs 10 Extend along the axis direction of wheel rim, and those convex ribs 10 are laid along wheel rim inner face circumferential direction uniform intervals.

In one better embodiment, those convex ribs 10 are from axial end face and the wheel rim that bcad seats 12 extends to wheel rim 13 The intersection in face, wherein 10 part of convex ribs is located at bcad seats 12, but not necessarily extends to the seat width of entire tyre bead 12.

In another better embodiment, those convex ribs 10 extend the width, entire wheel rim 13 for being related to entire bcad seats 12 The junction of width and bcad seats 12 and wheel rim 13.

The convex ribs 10 are 15-50mm along the development length of wheel rim axial direction, it is preferable that extension of the convex ribs 10 along wheel rim axial direction Length takes 40mm.

The width of the convex ribs 10 is 3-20mm, it is preferable that the width of the convex ribs 10 takes 12mm.

The height of the convex ribs 10 is 0.5-2.0mm, it is preferable that the height of the convex ribs 10 takes 1.2mm.

The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual In the range of type covers.
