Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and relates to an automotive chassis part, particularly a spring suspension ball seat. Background Technology

[0002] Suspension ball joints are used in automobile chassis to transmit torque and dampen vibrations. For example, Chinese patent literature discloses a suspension ball joint [Application No.: 202320012932.2; Authorization Announcement No.: CN218760900U], which includes a suspension ball joint, a ball cup installed inside the suspension ball joint, a ball pin that works with the ball cup inside the suspension ball joint, a base plate embedded and fixed on the inner wall of the suspension ball joint, and a dustproof component between the ball pin and the suspension ball joint to prevent dust from entering the interior of the suspension ball joint.

[0003] The aforementioned suspension ball joint has the advantage of good dust prevention, but its bottom plate is a flat plate, which cannot effectively buffer the ball pin when it is subjected to axial impact force, and is prone to damage. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a spring-suspended ball seat that can provide elastic support for the ball pin.

[0005] The objective of this utility model can be achieved through the following technical solution: A spring-loaded ball seat includes a suspension ball seat, a U-shaped base plate connected to the bottom of the inner wall of the suspension ball seat, a support spring connected to the bottom of the inner wall of the U-shaped base plate, a lower ball cup connected to the top of the support spring, a ball pin movably connected to the inner wall of the lower ball cup and the inner wall of the suspension ball seat, a telescopic dust cover fitted over the outside of the suspension ball seat, the top of the ball pin penetrating the suspension ball seat and the telescopic dust cover, a hexagonal slotted nut threaded onto the top of the ball pin, and tension springs connected to both sides of the top of the suspension ball seat, the top of the tension springs being connected to the top of the inner wall of the telescopic dust cover.

[0006] This spring-suspended ball joint utilizes a U-shaped base plate, a support spring, and a lower ball cup. The U-shaped base plate and support spring work together to provide elastic support to the lower ball cup, preventing damage from impacts from above due to lack of cushioning. Simultaneously, the U-shaped base plate stores lubricating oil, increasing lubrication space and facilitating ball pin lubrication. The tension spring facilitates the dust cover's rapid return of the ball pin to its original position and also supports the dust cover, preventing slippage of the upper part of the dust cover and interference with the ball pin's movement.

[0007] In the aforementioned spring suspension ball seat, several positioning holes are provided on both sides of the top of the suspension ball seat, and an annular groove for use with the telescopic dust cover is provided on the top of the outer surface of the telescopic dust cover. The positioning holes facilitate the use of bolts to position and install the suspension ball seat; the annular groove facilitates the stable mounting of the telescopic dust cover on the outside of the suspension ball seat.

[0008] In the aforementioned spring-suspended ball seat, the bottom of the telescopic dust cover is fitted with a double-ring flat clamp, which corresponds to an annular groove. The top of the telescopic dust cover is fitted with a single-ring round clamp, and an exhaust hole is provided on the top of one side of the inner wall of the telescopic dust cover. The double-ring flat clamp facilitates securing the bottom of the telescopic dust cover inside the annular groove; the single-ring round clamp facilitates the stable mounting of the top of the inner wall of the telescopic dust cover on the outside of the ball pin.

[0009] In the aforementioned spring-loaded ball seat, the bottom of the inner wall of the ball seat is provided with a groove for placing a ring to cooperate with the U-shaped base plate, and the bottom of the lower ball cup is provided with a bearing groove for cooperating with the support spring. The groove facilitates the extension of the outer side of the top of the U-shaped base plate into the interior of the ball seat, improving the stability of the U-shaped base plate connection.

[0010] In the aforementioned spring-suspended ball seat, a connecting screw groove is provided at the bottom of the inner wall of the U-shaped base plate. A sealing component is installed inside the connecting screw groove. The sealing component includes a threaded ring, the outer side of which is threadedly connected to the inner wall of the connecting screw groove. The sealing component provides a seal to the bottom of the U-shaped base plate.

[0011] In the aforementioned spring-loaded ball seat, the bottom of the threaded ring is connected to a threaded groove and a sealing disc. The bottom of the sealing disc has a rotating groove, and a rotating block is connected inside the rotating groove. The cooperation between the rotating groove and the rotating block facilitates the rotation of the sealing disc.

[0012] Compared with the prior art, this utility model uses the cooperation of a U-shaped base plate, a supporting spring, and a lower ball cup. The cooperation of the U-shaped base plate and the supporting spring can provide elastic support for the lower ball cup, avoiding collision damage caused by the lack of elastic buffer when the ball pin is impacted from above. At the same time, lubricating oil can be stored inside the U-shaped base plate, increasing the storage space for lubricating oil, which is beneficial for lubricating the ball pin and extending its service life.
