The steering string assembly is used to convert part of the mechanical energy produced by the engine (or motor) into pressure energy... The principle of steering string assembly steering system uses the energy required by the steering string assembly. Under normal circumstances, only a small part of the energy is provided by the driver, while the majority is the hydraulic energy (or pneumatic energy) provided by the oil pump (or air compressor) driven by the engine (or motor).Therefore, the study of safe steering wheel and steering control mechanism is an important topic of automobile safety, energy absorption steering wheel and energy absorption steering string is one of its achievements.
Energy sucking steering wheel
The steering wheel consists of a rim, spoke and hub. A fine-toothed spline in the hub of the steering wheel is connected to the steering shaft. The steering wheel is equipped with a horn button, and in some cars, the steering wheel is equipped with a speed-control switch and an airbag.
When the car crashes, the driver's head or chest is more likely to collide with the steering, thus increasing the injury index value of the head and chest. To solve this problem, the stiffness of the steering wheel can be optimized to reduce the collision stiffness of the driver as far as possible on the premise of meeting the requirements of steering rigidity. The skeleton can produce deformation to absorb impact energy and reduce the degree of injury of the driver. At the same time, the plastic cover of the steering wheel is softened as much as possible to reduce the surface contact stiffness
