What parts does the automobile steering system consist of?

The steering system consists of steering control mechanism, steering gear and steering transmission mechanism, and uses the driver's physical strength as steering energy.

At present, there are two kinds of steering systems: mechanical steering system, and steering energy is the driver's physical strength; The steering energy of power-assisted steering system includes the driver's physical strength and engine power, which is generally in vehicles with more than 50 tons.

The requirements for the steering system include: automatic alignment, light and sensitive operation, consistent rotation direction with the change of automobile driving, small recoil force transmitted to the steering wheel, and no natural vibration during driving.

For the trapezoidal mechanism with correct steering design, the wheels can rotate around the steering center when the car turns.

At present, the mature technical types are worm shaft type (WP type), worm roller type (WR type), circulating ball type (BS type) and rack and pinion type (RP type), which have been widely used in automobiles. The data show that the circulating ball steering gear accounts for about 45%, the rack-and-pinion steering gear accounts for about 40%, the worm-wheel steering gear accounts for about 10%, and other types of steering gear account for 5%.

Judging from the development trend, the sphere has developed steadily, especially in the use of buses, which has reached 100%.

The common faults of steering system are direction deviation, direction swing, heavy steering and insufficient steering.

According to the advantages of power steering, power steering system will become a trend, and it will not only be applied to large vehicles, because power steering system not only improves the maneuverability of the car, but also improves the driving safety.
