Abstract
The utility model discloses a steel ring spoke of a heavy vehicle. The steel ring spoke comprises a spoke plate and air holes evenly arranged on the periphery of an arc portion of the spoke plate. The steel ring spoke is characterized in that oval bosses protruding in the outer side of the arc are arranged between the air holes. The long axis of each oval boss is perpendicular to a connecting line of two adjacent air holes. The height of the oval boss is 1-2 millimeters. After the air holes are punched on the arc portion of the spoke, the middle of every two air holes are punched from the inner arc direction to the outer arc direction on a punching machine, consequently the arc bosses which concaves downwards on the inner arc and protrudes outwards on the outer arc so as to increase strength and rigidity of the arc portion and correspondingly increase the strength and rigidity of the steel ring spoke, and therefore safety and reliability of the spoke are improved, and service life of the steel ring spoke 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 a plurality of 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 ellipse around boss in the circular arc outside, the line at center, the adjacent two wind hole of the major axis of said ellipse around boss.
Further, the height of described ellipse around 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 ellipse around 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 ellipse around boss 3 in the circular arc outside is set between the described wind hole 2, and the axis of said ellipse around boss 3 is in the line at 2 centers, adjacent two wind holes.The height of described ellipse around 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 ellipse around boss in the circular arc outside is set between the adjacent two wind holes, and the axis of said ellipse around boss is in the adjacent two wind hole lines of centres.
2. autotruck steel ring spoke according to claim 1 is characterized in that: the height of described ellipse around boss is 1～2mm.
