Wheel and suspension brackets
- Maintenance or repair of the chassis and other vehicle systems is almost always accompanied by the dismantling of the wheels, while the replacement of any suspension part first of all begins with fasteners
During the repair, it is necessary to pay special attention to the condition of the fasteners, because repeated tightening/unscrewing of threaded connections damages the surface of the thread profile, which leads to an excessive value of the friction force during tightening. Thus, the tightening force prescribed by the automaker cannot be ensured, which will negatively affect the service life of silent blocks or suspension arms. In addition, during long-term operation, plastic deformations, thread damage, and corrosion occur on the fastener parts, which also requires the mandatory replacement of the fastener. For a qualified repair of the suspension and wheel fastening systems of a LYNXauto car, it is recommended to replace the fasteners.
For this purpose, a new product group was developed and introduced into the LYNXauto production program. DACROMET® protective coating (zincon-filled anti-corrosion coating), recognized as one of the most effective in the world, provides reliable protection and durability of LYNXauto threaded connections. Reliability and safety of operation is ensured by the 10th strength class due to the use of high-quality chromium-alloyed steel and heat treatment (up to 50 HRC). Strength parameters (compression, tension, shear) are designed using computer simulation and controlled on special tensile and shock stands according to JIS B 1051 and JIS B 1052-2 standards.
