Steering wheel process requirements
Because the driver often grips the steering wheel and keeps turning, it is required to select a material with good wear resistance to manufacture the steering wheel.
In a car accident, a car fire will endanger the safety of the occupants. To reduce the damage to the occupants, the interior trim parts, including the steering wheel, should be made of flame retardant materials. The relevant standards for evaluating the combustion performance are FMVSS 302, JISD 1201 and the like.
The reflection of the steering wheel is one of the reasons for the driver to dazzle, and it also hinders safe driving. The anti-glare related standards developed by foreign countries include FMVSS 107 and ADR 12.
The driver holds the rim of the steering wheel every moment, so the shape, size, etc. are required to meet the ergonomic requirements, and should not be fatigued for a long time.
The iron core is connected to each component by means of arc welding, resistance welding, riveting, and the like. With the development of the automotive industry, this process has been nearly eliminated, and instead, the hub, rim and spokes are connected by die-casting, and the inner core is also changed to die-casting. The use of aluminum-magnesium alloy material through the die-casting method not only simplifies the manufacturing process of the steering wheel, but also more importantly meets the requirements for product weight reduction.
