The steering knuckle is one of the main components on the steering axle of an automobile. The function of the steering knuckle is to withstand the load on the front of the automobile, support and drive the front wheels to rotate around the kingpin to steer the automobile. In the running state of a vehicle, it bears variable impact loads, so it is required to have high strength. At the same time, the steering system is an important safety component on the vehicle, and as the actuator of the steering system, the safety factor of the steering knuckle is self-evident.
In the repair kit for automobile steering knuckles, accessories such as kingpins, bushings, and bearings are involved, which affect the service life of the product. In addition to the material, the fit clearance between various components is also an important parameter related to product quality. Bushings, kingpins, and bearings have allowable work errors at the time of delivery, with upper and lower errors typically between 0.17-0.25dmm. In order to correct these work errors, Each set of steering knuckle repair kits sold by the BRK brand has been re measured and re paired. After replacing the kingpin more than twice, the bore diameter of some front axles will slightly increase.
What should I pay attention to when purchasing king pin kit
1. Check whether the trademark identification is complete. The outer packaging of authentic products is of good quality, with clear handwriting on the packaging box and bright overprinting colors. The packaging box and bag should be marked with the product name, specification, model, quantity, registered trademark, factory name, address, and phone number. Some manufacturers also mark their own labels on the accessories, and should carefully identify them when purchasing to prevent buying counterfeit and shoddy products.
2. Check the geometric dimensions for deformation. Some parts are prone to deformation due to improper manufacturing, transportation, and storage. During inspection, you can roll shaft parts around the glass plate to see if there is light leakage at the joint between the parts and the glass plate to determine whether they are bent.
3. Check whether the joint part is smooth. During the handling and storage of spare parts, due to vibration and bumps, burrs, indentations, damages, or cracks often occur at the joint parts, affecting the use of the parts. Pay attention to inspection when purchasing.
4. Check the surface of the parts for rust. The surface of qualified spare parts has both a certain degree of accuracy and a shiny finish. The more important the spare parts are, the higher the accuracy, the stricter the packaging for rust prevention and corrosion prevention. Attention should be paid to inspection when purchasing. If any rust spots, mildew spots, cracks, loss of elasticity of rubber parts, or obvious turning tool lines on the surface of the journal are found, they should be replaced.
5. Check whether the protective surface layer is intact. Most parts are factory coated with a protective layer. If you find that the sealing sleeve is damaged, the packaging paper is lost, or rust preventive oil or paraffin wax is lost during purchase, you should return and replace it.
