Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
Example 1
As shown in fig. 1, a ball stud assembly for automatically compensating for a gap includes a ball stud 1, a housing 2, an upper ball seat 3, and a lower ball seat 4. The ball head of the ball pin 1 is positioned in the mounting groove of the shell 2, and the other end of the ball head extends out of the shell 2. The upper ball seat 3 and the lower ball seat 4 are annular structures provided with openings 7, and the upper ball seat 3 and the lower ball seat 4 are expanded through the openings 7 under the action of force and are contracted outwards or inwards through the reduction of the openings 7 when the acting force is reduced or eliminated. The upper ball seat 3 and the lower ball seat 4 are respectively arranged in the mounting groove and sleeved at the positions of the upper part and the lower part of the periphery of the ball head of the ball pin 1, and the upper ball seat 3 and the lower ball seat 4 are in an outwards-expanded state under the action of the axial direction of the ball head at first so as to enable the upper ball seat 3, the lower ball seat 4 and the ball head of the ball pin 1 to have no gap. And an automatic compensation piece which is used for axially compressing the upper ball seat 3 and the lower ball seat 4 after the upper ball seat 3, the lower ball seat 4 and the ball head of the ball pin 1 are worn is further arranged in the mounting groove, so that no clearance between the upper ball seat 3 and the lower ball seat 4 and the ball head of the ball pin 1 is continuously ensured. The automatic compensation piece is a belleville spring 5 which is sleeved on the upper part of the ball head of the ball pin 1 and corresponds to the position above the upper ball seat 3, and the belleville spring 5 initially supports against the inner wall of the top of the mounting groove and the upper end face of the upper ball seat 3 up and down under the action of the assembly riveting force and is flattened, so that rebound axial compression of the upper ball seat 3 and the lower ball seat 4 is realized after the upper ball seat 3, the lower ball seat 4 and the ball head of the ball pin 1 are worn.
The ball stud assembly structure further includes a cover plate 6, an oil cup 8 and a dust cover 10. The cover plate 6 is riveted on the housing 2 and corresponds to the position of the bottom of the installation groove, and the cover plate 6 flattens the belleville spring 5 through the lower ball seat 4, the ball pin 1 and the upper ball seat 3 in sequence. As shown in fig. 2, the upper tee 3 and the lower tee 4 are each of a ring-like structure (C-like structure) provided with an opening 7, which is expanded outwardly or contracted inwardly by increasing or decreasing the opening 7. The oil cup 8 is mounted on a side wall of the housing 2 and is used for injecting lubricating oil into the mounting groove. The inner walls of the upper ball seat 3 and the lower ball seat 4 are provided with oil grooves 9 for introducing lubricating oil in the mounting grooves, and the oil grooves 9 are of a spiral structure. The lower end of the dust cover 10 is fixed at the position of the upper end of the shell 2 through a clamp 11, and the upper end of the dust cover is fixed at the corresponding position on the ball pin 1 after the periphery of the ball pin 1 extends a certain distance along the axial direction of the ball pin 1, so that the ball head of the ball pin 1 is sealed in the mounting groove.
