Description

Automobile outer pull rod and outer ball sleeve riveting assembly Technical Field The utility model relates to the technical field of outer pull rod assembly parts, in particular to an automobile outer pull rod and outer ball sleeve riveting assembly body. Background In an automobile suspension system, an assembly structure of an automobile outer pull rod and an outer ball sleeve plays a key role in the running stability of a vehicle. For example, the Chinese patent grant publication number is CN217029629U, which discloses a lower ball head of an automobile, the traditional outer pull rod and outer ball sleeve assembling structure has the problems of insufficient connection, easy loosening and the like, and relative movement is easy to occur between the outer pull rod and the outer ball sleeve, so that faults such as abrasion, abnormal sound and the like are caused, the service life and riding comfort of the automobile are influenced, and the traditional structure lacks an effective buffer mechanism during assembly, so that the damage of parts is easy to cause. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects in the prior art and providing an automobile outer pull rod and outer ball sleeve riveting assembly. The technical scheme adopted by the utility model is as follows: The riveting assembly of the automobile outer pull rod and the outer ball sleeve comprises a ball pin of the automobile outer pull rod and the outer ball sleeve matched with the ball pin, wherein the outer ball sleeve is in a cylindrical shape, a bottom plate with a circular cross section is processed at the top of the outer ball sleeve, the bottom plate is surrounded by inward wrapping edges of the top of the outer ball sleeve to form a semi-closed cavity, a plastic bearing is filled in the semi-closed cavity, the ball pin enters the semi-closed cavity from the outer ball sleeve and is arranged at intervals with the outer ball sleeve through the plastic bearing, and an opening of the outer ball sleeve is folded inwards to form an inner closing opening mutually attached with the ball pin. According to the technical scheme, through improving the assembly structure of the outer ball sleeve and the ball pin, the outer pull rod is better riveted, and the product quality and the service life are improved. In the process of edge covering and riveting, the outer ball sleeve tightly wraps and fixes the ball pin in the semi-closed cavity, so that reliable connection is formed. The plastic bearing can fill the gap between the ball pin and the outer ball sleeve, and can absorb part of impact force, so that the ball pin and the outer ball sleeve are prevented from being damaged due to direct collision. In addition, the automobile outer pull rod and outer ball sleeve riveting assembly provided by the utility model can also have the following additional technical characteristics: In accordance with one embodiment of the present utility model, The plastic bearing is U-shaped, and is provided with an arc-shaped inner edge which is contacted with the ball pin. The arc inner edge of this technical scheme for thereby avoid the contact card to stop for adapting the ball round pin shape better, dodge the ball round pin. According to one embodiment of the utility model, a mesh gap is arranged between the plastic bearing and the bottom plate. The reticular gap of the technical proposal is used for providing a certain space for the deformation and the movement of the plastic bearing in the assembly body and relieving the stress concentration. According to one embodiment of the utility model, the plastic bearing is made of wear-resistant engineering plastic. According to one embodiment of the utility model, the plastic bearing is of a split or integral structure. In the technical scheme, the split plastic bearing can be assembled into a complete plastic bearing, and the split plastic bearing is directly placed into the semi-closed cavity. The split type advantage lies in low processing cost, and the integral type advantage lies in the assembly is simple. According to one embodiment of the utility model, the ball pin forms an interference fit with the outer ball sleeve through a plastic bearing. The interference fit of this technical scheme for strengthen the connection compactness between ball round pin and the outer ball cover, prevent that the ball round pin from becoming flexible in the outer ball cover. Compared with the prior art, the utility model has the following beneficial effects: The plastic bearing made of wear-resistant engineering plastic can absorb impact force, avoid direct collision damage of the ball pin and the outer ball sleeve, and the netlike gap provides space for deformation movement of the plastic bearing, thereby relieving stress concentration.
