Abstract
The utility model discloses a steel ring spoke of a lorry. The steel ring spoke comprises a spoke plate and vents, wherein vents are distributed in an arc part of the spoke plate uniformly and circumferentially; the steel ring spoke is characterized in that a long circular boss is arranged between each two adjacent vents, wherein the outer side of the arc of each long circular boss is bulged; the long axis of each long circular boss is perpendicular to the connection line between central points of the two adjacent vents; and the long circular boss is 1-2mm high. According to the steel ring spoke of the lorry, after the vents are punched in the arc part of the spoke, the stamping is conducted on a punching machine and between the two adjacent vents from the inner arc to the outer arc, so that the long circular bosses of which the inner arcs are sunken downwards and the outer arcs are bulged outwards is formed by the spoke, thereby enhancing the strength and the rigidity of the arc part; and meanwhile, the strength and the rigidity of the steel ring spoke are enhanced correspondingly, the safety and the reliability of the spoke are enhanced, and the service life of the steel ring spoke of the lorry is prolonged.
Description
Technical field
The utility model relates to a kind of automobile spoke, particularly a kind of autotruck steel ring spoke.
Background technology
Be evenly distributed with several waist shapes or circular breather port in the prior art on the spoke of motor tire steel ring, so that distributing of the heat on tire and the wheel rim is serial like 8.25V.But because spoke is stretch forming, the thickness of the thickness of the circular arc portion steel plate of the back disc that stretches steel plate during less than normal blanking, thereby the strength and stiffness of the circular arc portion of disc are minimum.Behind the wind hole, owing to the destruction of wind hole to strength of material and rigidity, material deforms after stressed, set up stresses, thus cause in-use performance to descend, spoke is ruptured.Usually the destruction of the spoke beginning from the wind hole mostly, spoke causes whole steel ring to be scrapped after destroying, and seriously also possibly cause traffic accident and generation.
Summary of the invention
The purpose of the utility model is to overcome weak point of the prior art, and the Automobile steel ring spoke that a kind of strength and stiffness increase, increase service life, safe reliability improves is provided.
To achieve these goals; The technical scheme of the utility model is: a kind of autotruck steel ring spoke; Comprise disc, the circumferential well-distributed wind of disc circular arc portion hole; It is characterized in that being provided with between the described wind hole the protruding Long Circle boss in the circular arc outside, the axis of said Long Circle boss is in the line of two wind central point of hole.
Further, the height of described Long Circle boss is 1～2mm.
The beneficial effect of the utility model is: behind the circular arc portion stamping-out wind hole; On punch press, in the middle of the two wind holes by interior circular arc to the punching press of external arc direction; Thereby make spoke form in circular arc to lower recess, external arc Long Circle boss to outer lug, thereby increased the strength and stiffness of circular arc portion, correspondingly increased the strength and stiffness of steel ring spoke; Improve the safe reliability of spoke, prolonged the service life of Automobile steel ring spoke.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the lateral plan of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As depicted in figs. 1 and 2; The autotruck steel ring spoke of the utility model; Comprise disc 1, the circumferential well-distributed wind of disc 1 circular arc portion hole 2; The protruding Long Circle boss 3 in the circular arc outside is set between the described wind hole 2, and the axis of said Long Circle boss 3 is in the line of two wind holes, 2 center-points.The height of described Long Circle boss is 1～2mm.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
Claims (2)
1. autotruck steel ring spoke; Comprise disc, the circumferential well-distributed wind of disc circular arc portion hole; It is characterized in that: the protruding Long Circle boss in the circular arc outside is set between the described wind hole, and the axis of said Long Circle boss is in the line of two wind central point of hole.
2. autotruck steel ring spoke according to claim 1 is characterized in that: the height of described Long Circle boss is 1～2mm.
