[0002] The outer ball joint is a crucial component of a car's steering system. Located between the steering mechanism and the wheels, it plays a vital connecting role, ensuring the wheels can flexibly change direction with the steering wheel. The outer ball joint can rotate at multiple angles, contributing to smooth steering and handling stability. It also effectively dampens road vibrations, enhancing driving comfort. Connecting the steering tie rod and steering knuckle, the outer ball joint ensures the vehicle's steering agility and stability, allowing the wheels to turn left and right according to the driver's control. The design of the outer ball joint incorporates needle rollers embedded in the grooves of the ball joint's inner bore, helping to reduce ball joint wear and improve the tensile strength of the main shaft. The outer ball joint directly affects the vehicle's handling stability, operational safety, and tire lifespan, ensuring the correct movement relationship between the left and right steering wheels, thereby improving overall vehicle performance.

[0003] However, traditional steering ball joints have the following disadvantages:

[0004] The ball joint can interfere with the ball joint housing during movement, which can cause abnormal noises when the vehicle is steering and shorten the service life of the outer ball joint. Utility Model Content

Movable grooves 42 are provided at both ends of one side of the first shell 41 and at both ends of one side of the extension shell 43. The two ends of the other side of the extension shell 43 and the two ends of one side of the second shell 44 are respectively fixedly connected to one side of the four movable parts 45. The four movable parts 45 are respectively arranged corresponding to the four movable grooves 42.

[0027] A cover plate 5 is fastened to the bottom of the connection between the ball pin seat 3 and the ball pin housing 4.

[0028] A connecting hole 6 is provided at the end of the ball pin housing 4 away from the ball pin seat 3, and the ball pin housing 4 is assembled at the point of use through the connecting hole 6.

[0029] Two symmetrically arranged limiting grooves 8 are provided on the two sides of the ball pin housing 4 away from the ball pin seat 3. The limiting grooves 8 facilitate the ball pin housing 4 to be engaged and installed at the place of use.

[0030] Sliding frames 74 are fixedly installed on both sides of the length block 72. The two sliding frames 74 slide with the two clamping plates 73 respectively. The installation of the sliding frames 74 limits the sliding distance of the clamping plates 73.

[0031] A connecting spring 75 is fixedly installed on one side of each of the two clamping plates 73. The ends of the two connecting springs 75 away from the clamping plates 73 are fixedly connected to the side of the length block 72 directly opposite. When the user presses the clamping plate 73, the clamping plate 73 squeezes the connecting spring 75 from one side.

The two clamps 73 are fastened together from the grooves on both sides of the inner wall of the mounting location, completing the connection between the outer ball head and the mounting location. Alternatively, the ball pin housing 4 is assembled at the usage location through the connecting hole 6. As the steering wheel rotates, the ball pin 1 needs to rotate around its own axis or swing in the lateral or longitudinal direction within the ball pin seat 3. To ensure that the vehicle does not experience steering noise, the ball pin 1 must not interfere with the ball pin housing 4 during movement. In existing designs, the ball pin housing 4 is symmetrically designed at the ball pin opening 10, so that the minimum angle requirement can be met on both symmetrical sides. (Refer to the appendix of the instruction manual.) Figure 6-7 The ball pin shell 4 is designed with an angle, that is, the axis of the ball pin shell 4 is designed with an angle to the corresponding axis.
