As a flexible connection point, it withstands different forces during wheel steering and suspension movement, ensuring smooth vehicle handling and steering while driving. This allows the car to maintain good handling performance even on bumpy roads.

[0003] Most ball heads on the market currently use a single, full-size ball head, resulting in a larger contact area and greater friction. Utility Model Content

[0007] A base is disposed within the receiving groove, comprising a ball socket and a ramp, wherein the ramp is provided with a through hole;

[0008] The ball head includes an upper hemisphere and a lower hemisphere, the diameter of the lower hemisphere is smaller than the diameter of the upper hemisphere, the upper hemisphere contacts the inner wall of the receiving groove for the ball pin to dislodge, and at least part of the lower hemisphere is disposed in the ball socket.

[0009] The base is made of metal.

[0010] The bottom of the housing is provided with an oil nozzle, and a grease injection channel is provided between the through hole and the oil nozzle.

[0011] The outer wall of the upper hemisphere is provided with channels.

[0012] It also includes a dust cover, one end of which is connected to the pin, and the other end of which is connected to the outer wall of the housing.

[0013] The outer circumferential wall of the housing is provided with an annular groove for mounting the dust cover at one end.

[0014] The bottom of the housing is provided with a mounting hole, and the oil nozzle includes a connecting pipe, which is threadedly connected to the inner wall of the mounting hole.

[0015] The trench has two or more sections.

[0016] The beneficial effects of this utility model are: This utility model provides a high-life, low-friction ball head. The ball pin structure reduces the contact area with the ball seat, greatly reducing friction. Lowering friction can reduce wear, thereby extending the service life of the ball head. Attached Figure Description

[0017] Figure 1 This is a structural schematic diagram of one embodiment of the present invention.

[0018] Figure 2 This is a partial perspective view of one embodiment of the present invention. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings. A high-life, low-friction ball joint includes a housing 1 and a pin 2. Part of the pin extends into the housing and is provided with a ball joint 4. A receiving groove 11 is provided inside the housing. A base 3 is provided inside the receiving groove, which includes a ball socket 31 and a ramp 32. A through hole 321 is provided on the ramp. The ball joint includes an upper hemisphere 41 and a lower hemisphere 42. The diameter of the lower hemisphere is smaller than the diameter of the upper hemisphere. The upper hemisphere contacts the inner wall of the receiving groove for the ball pin to disengage. At least part of the lower hemisphere is located in the ball socket. The top of the receiving groove is tapered, and the upper hemisphere cooperates with it to prevent disengagement. This is a prior art design. The contact area between the lower hemisphere and the ball socket is smaller, reducing friction. On the other hand, the through hole is for grease to enter and is provided on the ramp for easy grease entry. Conventionally, it is provided at the bottom of the ball socket, which makes it difficult for grease to enter.

[0020] In this embodiment, as shown in the figure, the base is made of metal. Compared to traditional plastic ball seats, metal ball seats can achieve a high surface finish through precision casting and machining, ensuring a tight fit between the ball head and the ball seat.

[0021] In this embodiment, as shown in the figure, an oil nozzle 5 is provided at the bottom of the housing, and a grease injection channel is provided between the through hole and the oil nozzle. This allows for direct oil injection, making it more convenient to use. The oil nozzle design provides continuous lubrication and reduces friction. The metal ball inside the ball head and the ball seat withstand high-frequency shearing and impact forces during vehicle operation. The lubricating grease effectively reduces direct contact between metal surfaces, lowers friction loss and heat generation, and delays wear and aging.

[0022] In this embodiment, as shown in the figure, the outer wall of the upper hemisphere is provided with grooves 411. Grease can enter for convenient lubrication.

[0023] In this embodiment, as shown in the figure, a dust cover 6 is also included. One end of the dust cover is connected to the pin, and the other end of the pin is connected to the outer wall of the housing. This serves to prevent dust and foreign objects from entering the housing.

[0024] In this embodiment, as shown in the figure, the circumferential outer wall of the housing is provided with an annular groove 12 for mounting the dust cover at one end. This makes the installation more secure. It effectively prevents the dust cover from falling off due to pressure during sharp turns, improving not only the product's safety and durability but also further optimizing the vehicle's handling stability.

[0025] In this embodiment, as shown in the figure, the bottom of the housing is provided with a mounting hole, and the oil nozzle includes a connecting pipe, which is threadedly connected to the inner wall of the mounting hole.

[0026] In this embodiment, as shown in the figure, there are two or more channels.
