A wheeled device for controlling the direction of travel of an automobile, ship, aircraft, etc. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque and then transmit it to the steering shaft. The original car was controlled by the rudder. The violent vibration generated in the driving of the car is transmitted to the driver, which increases the difficulty of controlling the direction. When the engine was installed in the front of the car, due to the increase of weight, the driver could not use the rudder to drive the car at all. This new design of steering wheel came into being. The gear system introduced between the driver and the wheel operates flexibly and is well insulated from the violent vibration from the road. Moreover, a good steering wheel system can also bring the driver a feeling of intimacy with the road.

There should be four main meters, namely tachometer, and other.

More than 120 years ago, the steering wheel originally placed on the steam vehicle by the automobile inventor was installed on the vertical steering column. Its defect is that it is not conducive to the manipulation of the driver and hinders the line of sight. In the autumn of 1887, the repairmen of Daimler automobile company in Germany overhauled a fiton near car driven from Strickland. When the crane worker hoisted the repaired body back for assembly, the hook suddenly slipped out and the body fell on the steering column. As a result, the steering column was bent several degrees from the vertical position. A repairman tried to correct the bent steering column, but unexpectedly found that the new angle made the steering wheel no longer difficult to operate and obstructed the line of sight.

Daimler rewarded the repairmen for their unexpected discovery, and dispatched researchers to immediately improve the assembly process of the steering wheel. In 1890, pailisheng Automobile produced by Daimler automobile company was equipped with inclined steering column and inclined steering wheel for the first time. Automobile companies in various countries have followed suit, making the steering wheel more and more fixed and perfect. In addition, the steering wheel can also refer to the instrument used by the army Scout or geodesic to measure the azimuth angle. It is composed of lens, level gauge, magnetic needle, angle frame, etc. Most cars install airbags on the steering wheel, which can reduce the impact of the steering wheel on the driver in a collision, so as to protect the driver's safety.
