Abstract
The utility model relates to a stamped piece type universal joint fork which is particularly used on a steering mechanism of a sedan or a miniature car and belongs to the technical field of automobile accessories. The universal joint fork comprises a universal joint fork body, the two lugs of the universal joint fork body are respectively provided with two coaxial holes, and a spline hole is formed in the universal joint fork body. The universal joint fork is characterized in that arcs are arranged at the connecting parts of the universal joint fork body with the two lugs, and the radius R of the transition arcs is 25 mm. A reinforcing rib is arranged on the universal joint fork body for increasing rigidity and strength. Torsion alternating stress can be dispersed, the rigidity and the strength can be enhanced, the universal joint fork is safe and reliable, and the service life of the universal joint fork can be prolonged.
Description
Technical field
The utility model relates to a kind of blanked part formula joint yoke, is the steering hardware for car or minicar specifically, belongs to the vehicular spare parts technical field.
Background technology
Steering hardware is a critical component on the automobile, and it is the security personnel's parts on the automobile, and its effect is the travel direction of adjusting and change automobile.Joint yoke is positioned at end and the joining place of steering wheel of steering hardware lower drive shaft combination.At joint yoke head two ears two coaxial apertures are arranged, in order to needle bearing to be installed and to link to each other with center cross, play universal coupling, joint yoke has been carried splined hole on the body, be connected with steering wheel input shaft spline axle head, and with lock bolt it is locked, thereby the torsion that the bearing circle transmission is come is transferred to wheel flutter by steering hardware, realizes wheel steering.
But the steering shaft of automobile all will carry out hundreds and thousands of times rotations owing to every day, and joint yoke is in always and turns among the reverse stress, easily produces fatigue, causes distortion, affects service life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of blanked part formula joint yoke is provided, and can make to reverse the reverse stress dispersion, can strengthen rigidity and intensity, and is safe and reliable, and can prolong the service life of this part.
The technical scheme that provides according to the utility model, a kind of blanked part formula joint yoke comprises the joint yoke body, described joint yoke body two ears are respectively equipped with two coaxial apertures, described joint yoke body is provided with splined hole, feature is: the described joint yoke body back side and two ear junctions are equipped with circular arc, and described transition arc R is 25mm.
Be provided with reinforced rib on the joint yoke body, increase its rigidity and intensity.
Compared with the prior art the utility model has the following advantages:
The utility model is owing to adopting the great circle arc transition at the joint yoke body back side and two ear junctions, make and reverse reverse stress and disperse, eliminated the transition of original design small arc-shaped and caused and reverse reverse stress and concentrate to joint fork center, the back side and cause rising the excessive hidden danger that causes joint back of the body center burst of stress; Owing to being provided with reinforced rib at the joint yoke body, strengthened rigidity and intensity, safety performance has obtained the failure-free assurance, has also prolonged the service life of this part.

Fig. 2 is the utility model structure birds-eye view.
Fig. 3 is the A-A cross section view of Fig. 2.
The specific embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, comprise joint yoke body 1, be provided with circular arc 2 at joint yoke body 1 back side and two ear junctions, owing to adopting arc transition, make and reverse the reverse stress dispersion: described circular arc R is 25mm; Be provided with reinforced rib 3 on the joint yoke body, reinforced rib 3 increases its rigidity and intensity.Described joint yoke body 1 head two ears are respectively equipped with two coaxial apertures 4, in order to needle bearing to be installed and to link to each other with center cross, play universal coupling, described joint yoke body 1 is provided with splined hole 5, splined hole 5 is connected with steering wheel input shaft spline axle head, and with lock bolt it is locked; Thereby the torsion that the bearing circle transmission is come is transferred to wheel flutter by steering hardware, realizes wheel steering.
