Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, and relates to an automotive chassis part, and particularly to an automotive control arm assembly. Background Technology
[0002] There are many types of automotive parts, including automotive control arm assemblies. In existing automotive control arm assemblies, the ball joint and ball seat lack effective sealing protection, allowing external dust to easily enter the gap between them. When the two rotate relative to each other, friction damage can easily occur, and the bottom of the ball seat is also prone to impact damage. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an automotive control arm assembly that can provide sealed protection for the ball pin and ball seat and has good shock absorption properties.
[0004] The objective of this utility model can be achieved through the following technical solution: an automotive control arm assembly, including an arm body, a bushing connected to one side of the arm body, a connecting sleeve connected to the other side of the arm body, a ball pin installed on the inner wall of the connecting sleeve, a ball seat embedded between the outer side of the ball pin and the inner wall of the connecting sleeve, a base plate connected to the bottom of the ball seat, a dust cover fitted on the top of the outer side of the connecting sleeve, a double-ring flat clamp and a single-ring round clamp respectively fitted on the bottom and top of the outer side of the dust cover, a protective cover fitted on the outer side of the dust cover, the top of the ball pin penetrating the connecting sleeve, the dust cover and the protective cover, the top of the inner wall of the dust cover fitted on the outer side of the ball pin, and a sealing rubber block connected to the bottom of the base plate.
[0005] This automotive control arm assembly, through the combined use of a protective cover, a single-ring round clamp, a dust cover, a double-ring flat clamp, a base plate, and a sealing rubber block, can seal and protect the ball pin and ball seat, preventing dust from entering the gap between the ball pin and ball seat, which would cause excessive friction during rotation, ultimately leading to friction damage and reduced service life. The sealing rubber block acts as a buffer and shock absorber, preventing damage to the connecting sleeve and extending its service life.
[0006] In the aforementioned automotive control arm assembly, the bottom of the inner wall of the connecting sleeve is provided with a mounting groove for use with the base plate. The bottom of the ball pin is connected to the top of the base plate, and the outer side of the ball seat contacts the inner wall of the connecting sleeve. The mounting groove facilitates the installation of the base plate at the bottom of the connecting sleeve.
[0007] In the aforementioned automotive control arm assembly, the bottom and top of the dust cover are respectively fitted with a lower retaining ring groove and an upper retaining ring groove for use with a double-ring flat clamp and a single-ring round clamp. The engagement of the lower and upper retaining ring grooves facilitates the installation of the double-ring flat clamp and the single-ring round clamp onto the dust cover.
[0008] In the aforementioned automotive control arm assembly, a bearing is movably fitted onto the top of the ball pin, and a buffer sleeve is fitted around the bearing. The outer side of the buffer sleeve is connected to the inner wall of the protective cover. The cooperation between the bearing and the buffer sleeve facilitates the rotation of the protective cover.
[0009] In the aforementioned automotive control arm assembly, connecting blocks are attached to both ends of the arm body, and connecting holes are provided through the connecting blocks. The connection blocks and connecting holes facilitate the installation of the arm body onto the vehicle body using bolts.
[0010] Compared with the prior art, this utility model uses a protective cover, a single-ring circular clamp, a dust cover, a double-ring flat clamp, a base plate, and a sealing rubber block to seal and protect the ball pin and ball seat, preventing dust from entering the gap between the ball pin and ball seat, which would cause greater friction during rotation, ultimately leading to friction damage and reduced service life. Furthermore, the sealing rubber block can provide buffer protection for the connecting sleeve, extending its service life. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0016] like Figure 1 , Figure 2 and Figure 3As shown, the vehicle control arm assembly includes an arm body 1. A bushing 9 is connected to one side of the arm body 1, and a connecting sleeve 14 is connected to the other side of the arm body 1. A ball pin 6 is installed on the inner wall of the connecting sleeve 14. A ball seat 7 is embedded between the outer side of the ball pin 6 and the inner wall of the connecting sleeve 14. A base plate 8 is connected to the bottom of the ball seat 7. A dust cover 4 is fitted on the top of the outer side of the connecting sleeve 14. A double-ring flat clamp 5 and a single-ring round clamp 3 are fitted on the bottom and top of the outer side of the dust cover 4, respectively. A protective cover 2 is fitted on the outer side of the dust cover 4. The top of the ball pin 6 passes through the connecting sleeve 14, the dust cover 4, and the protective cover 2. The top of the inner wall of the dust cover 4 is fitted on the outer side of the ball pin 6. A sealing rubber block 15 is connected to the bottom of the base plate 8.
