Fourth, the ball pin is composed of a structure;
There are two main types of ball studs: one is a combination of a spherical pin and an integral ball seat; the other is a combination of a hemispherical ball pin and a spherical member. In the past, coil springs were used for preloading and compensating for wear. Nowadays, synthetic resin pellets with elasticity and lubrication are widely used, which reduces the cost and improves the steering stability. In addition, the material and shape of the dust cover, the type of grease, etc. have been greatly improved, the grease nipple has been eliminated, and a maintenance-free structure has been realized.
The ball stud is mainly composed of an end cap, a ball pin, a ball seat and a dust cover. The end caps of the ball pin are mostly made of steel stamping parts, and the materials are mainly carbon steel, and some are also made of aluminum alloy or ductile iron. The machining precision of the ball pin surface is high, and the alloy steel with good hardenability is often used. The surface of the ball pin matched with the metal ball needs to be surface hardened by high-frequency quenching to improve wear resistance. Nowadays, the ball pin is used in combination with the non-metallic ball seat, so it is only necessary to adjust the ball pin. The choice of ball pin diameter should be considered based on factors such as tensile strength and durability.
The material of the ball seat is case hardened steel, powder metallurgy, nylon, polyacetal resin, polyurethane and polyester elastomer. Since the material and shape of the ball seat have a great influence on wear and fatigue life, the material is immersed in molybdenum disulfide or oil to improve wear resistance.It is also possible to add reinforcing ribs or composite materials to the tee.
The tightness of the dust cover greatly affects the wear and fatigue life of the ball stud. The material is mostly made of polyurethane or neoprene which is resistant to high temperature, oil and aging. In addition, the design should consider the deformation of the movement, so as to prevent the dust from entering the ball pin from the mating surface after deformation. At the same time, the matching precision of the dust cover and the related parts also has a great influence on the sealing property and the service life.
Five, the ball pin pin high frequency induction quenching process detailed
High-frequency induction hardening requirements: According to different vehicle requirements, super-audio induction hardening equipment and medium-frequency quenching equipment can be used to quench the surface of the ball pin)
Generally, there are differences in quenching positions according to different types of ball pin models. For example, the effective depth of high-frequency quenching of heavy-duty ball pins is generally 2-3 mm , and the quenching position requires the ball head and the ball pin to be quenched as a whole. For the ball surface treatment of the car, no integral quenching is required, and only the quenching of the ball head can satisfy the wear resistance and tensile strength.

The manufacturing process of the ball pin: round steel cutting - super audio induction heating - forging - cutting - high frequency quenching - assembly.
In order to prevent the occurrence of different products, defective products, incorrect assembly, etc., corresponding measures to prevent mistakes have been taken, and a full digital inspection machine capable of checking torque, shaking angle, etc., and combining these in various processes in.
Sixth , ball head pin high frequency quenching performance requirements
1 , should have sufficient swing angle to meet the requirements of the wheel up and down;
2 , the small friction torque is an important factor to ensure steering flexibility and easy handling;
3. There should be no gaps causing wheel wobble and abnormal noise;
4 , the sealing performance is good, to ensure that the ball pin can be used normally in muddy water and high temperature environment;
5 , should have sufficient strength and durability to withstand the forces and vibrations from the wheel.
