Abstract
The utility model relates to a ball seat structure in an automobile swing arm sphere joint assembly and belongs to the technical field of structural improvement of the automobile swing arm sphere joint assembly. The ball seat structure comprises a ball seat body with a vertical groove, an annular groove is arranged on an inner spherical surface of the ball seat body, and a plurality of evenly-distributed protrusions are arranged on an opening end face of the upper portion of the ball seat body. The ball seat structure can effectively improve lubrication of the sphere joint assembly, improves fatigue property and prolongs service life.
Description
Technical field
The utility model relates to the ball socket structure in a kind of automobile swing arm ball joint assembly, belongs to the architecture advances technical field of automobile swing arm ball joint assembly.
Background technique
The automobile swing arm ball joint assembly is as the important spare part in the automobile chassis swing arm, and whether the good job of its quality directly affects vehicle service life length and driving safety.For working life and the safety that guarantees connector assembly, not only need the material of high-quality, reasonably structure and good cooperation, the sufficient lubrication in the assembly using process is also most important.
Summary of the invention
But the utility model provides a kind of Effective Raise automobile swing arm ball joint assembly lubricated and wear resistance, thereby increases the ball socket structure of its fatigue behaviour.
For achieving the above object, the technological scheme that adopts of the utility model is:
Ball socket structure in a kind of automobile swing arm ball joint assembly, comprise the ball seat body with vertical groove, offer annular groove (annular groove circumferentially rounds along the inner ball surface level) on the inner ball surface of described ball seat body, be provided with several equally distributed projections on the upper opening end face of ball seat body.
As the further setting of such scheme, described annular groove is provided with two altogether, lays respectively at the inner ball surface top and bottom of ball seat body.
Described projection and the one by one corresponding setting of vertical groove (namely the number of the number of projection and vertical groove is identical, simultaneously the corresponding projection in each vertical groove upper end open place), and vertical groove upper end open is divided into left and right sides two-part with projection.
The height of described projection is 0.2-0.8mm.
The utility model increases in the inner ball surface (with the ball pin fitting surface) of ball seat body annular groove, and reducing the friction fit of ball seat and ball pin, and fat easy to lubricate enters the fatigue behaviour of raising assembly; Increase the many places projection at the upper opening end face of ball seat body, can alleviate the instable problem of assembly shaking moment that causes because of ball seat manufacturing tolerances or distortion after the assembling.
The utility model also can change by the size of suitable adjustment ring connected in star running torque and the shaking moment size of assembly, but does not affect its maximum axial displacement amount.
In a word, the ball socket structure of this type is simple, and low cost of manufacture is applied widely, can generally be used for the swing arm of kind of different automobile types.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, ball socket structure in a kind of automobile swing arm ball joint assembly of the utility model comprises with the ball seat body 1 of vertical groove 2, offers annular groove 3 on the inner ball surface of ball seat body 1, and annular groove 3 is provided with two altogether, lays respectively at the inner ball surface top and bottom of ball seat body 1.Be provided with on the upper opening end face of ball seat body 1 several equally distributed protruding 4.Projection 4 and the one by one corresponding setting of vertical groove 2, and vertical groove 2 upper end open are divided into left and right sides two-part with projection 4.Wherein, the height of projection 4 is 0.2-0.8mm.
The utility model has annular groove 3 in inner ball surface (with the ball pin fitting surface) increase of ball seat body 1, reduced the area of contact of ball seat and ball pin, alleviate friction, and lubricating grease is easier enters into annular groove 3 places by vertical groove 2, strengthens lubricated and indirectly improve the fatigue behaviour of assembly.Upper opening end face at ball seat body 1 increases many places projection 4, how much alleviate the instable problem of assembly shaking moment that causes because of ball seat manufacturing tolerances or distortion by the distortion of this raised points during assembling, make swing and the running torque maintenance within the specific limits.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
