Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile ball head assembly. Background Art

[0002] The ball joint assembly, also called the ball pin assembly, is one of the most important components in the automobile suspension system. It mainly bears the load transfer and steering during the driving of the vehicle, and plays a key role in the vehicle's handling stability, ride smoothness and safety.

[0003] During the use of the car, the ball head will often become loose between the ball shell due to wear. This situation may affect the stability and comfort of the car at the least, and may interfere with the movement of the car parts, destroy the geometric distribution, such as the front wheel toe, and accelerate the damage of parts, such as tire wear, etc. In severe cases, the car ball head may be dragged out of the ball shell, causing vehicle operation failure, leading to serious mechanical accidents or even major car crashes and fatalities. The lubricity is also poor, and the wear is large, which shortens the service life. Therefore, a person skilled in the art provides an automobile ball head assembly to solve the problems raised in the above background technology. Utility Model Content

[0010] Furthermore, a dust cover is provided on the outside of the rod portion, and the dust cover is fixedly connected to the upper part of the ball seat.

[0011] Through the above technical solution, by setting up a dust cover, mud, water and dust can be effectively prevented from entering the interior, thereby extending the service life of the product.

[0012] Furthermore, the oil nozzle and the through hole are fixedly connected.

[0013] Through the above technical solution, the oil nozzle is fixedly connected to the through hole, so that the grease enters the interior of the ball seat through the through hole.

[0014] Furthermore, the ball head is rotatably connected to the inside of the ball seat.

[0015] Through the above technical solution, the ball head can be rotated inside the ball seat to adapt to installation and working conditions at different angles.

[0016] Furthermore, the right portion of the ball seat is fixedly connected with a joint body.

[0017] Through the above technical solution, the ball seat can be firmly connected to other components of the mechanical system by setting the joint body.

[0018] Furthermore, the bottom ball bowl is slidably connected to the inside of the base.

[0019] Through the above technical solution, the upper ball bowl and the bottom ball bowl can be moved upwards by sliding the bottom ball bowl inside the base.

[0020] Furthermore, the first upper ball bowl, the first lower ball bowl and the bottom ball bowl are all slidably connected inside the ball seat.

[0021] Through the above technical solution, the first upper ball bowl, the first lower ball bowl and the bottom ball bowl slide inside the ball seat, so as to keep in close contact with the ball head, thereby reducing looseness between the ball head and the first upper ball bowl, the first lower ball bowl and the bottom ball bowl.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, through the cooperation among the ball seat, the ball head, the rod, the first lower ball bowl, the bottom ball bowl, the first upper ball bowl, the first spring and the third spring and other structures, when the first upper ball bowl, the first lower ball bowl and the bottom ball bowl are worn, under the elastic force of the first spring, the second spring and the third spring, the first upper ball bowl and the bottom ball bowl move upward, and the first upper ball bowl moves downward, and keeps in close contact with the ball head, thereby reducing the looseness between the ball head and these ball bowls and improving the stability of the system.

[0024] 2. In the utility model, the coordination among the structures such as the oil nozzle, ball seat, oil nozzle sleeve, connecting belt, through hole, dust cover and joint body ensures good lubrication inside the ball seat, which helps to reduce friction and wear. The dust cover can effectively prevent mud, water, dust and other impurities from entering the interior, protecting the internal parts of the device from the influence of the external environment, thereby extending the service life of the product and maintaining its stable performance.
