Abstract
The utility model discloses a steel rim spoke of a heavy truck, and the steel rim spoke comprises a spoke plate, air holes which are uniformly distributed on an arc part of the spoke plate along the circumferential direction, and elliptic blind holes which are arranged between every two adjacent air holes and sunken inwards, wherein the long axis of the elliptic blind holes is vertical to the joint line of every two adjacent air holes. The depth of each elliptic blind hole is 1 to 2mm. The steel rim spoke of the heavy truck has beneficial effects that after the air holes are punched on the arc part, the blind holes are squeezed from outside to inside between every two adjacent air holes, so that the strength and the rigidness of the arc part are improved, the strength and the rigidness of the steel rim spoke are correspondently improved, the safety and reliability of the spoke are improved, and the service life of the car steel rim 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 in the middle of the phase heart two wind holes the oval blind hole of depression from outside to inside being set, the axis of said oval blind hole is in the line in adjacent two wind holes.
Further, the degree of depth of described oval blind hole is 1～2mm.
The beneficial effect of the utility model is: behind the circular arc portion stamping-out wind hole; Ecto-entad squeezes out blind hole in the middle of the wind hole; Thereby the strength and stiffness of circular arc portion have been increased; Correspondingly increase the strength and stiffness of steel ring spoke, improved 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; It is characterized in that in the middle of the adjacent two wind holes 2 the oval blind hole 3 of depression from outside to inside being set, the axis of said oval blind hole 3 is in the line at 2 centers, adjacent two wind holes, and the degree of depth of described oval blind hole 3 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 oval blind hole of depression from outside to inside is set in the middle of the adjacent two wind holes, and the axis of said oval blind hole is in the line at center, adjacent two wind hole.
2. autotruck steel ring spoke according to claim 1 is characterized in that: the degree of depth of described oval blind hole is 1～2mm.
