1. Function:
A special mechanism for changing or restoring the driving direction of a vehicle.
2. Composition:
Steering control mechanism
Steering gear
Steering transmission mechanism

3、 Steering system terminology
1. Steering center and turning radius
(1) Steering center: when the vehicle turns, all wheel axes are required to intersect at one point, which 0 is called the steering center.
(2) Turning radius: the distance r from the steering center 0 to the contact point between the outer steering wheel and the ground is called the turning radius of the vehicle
2. Steering trapezoid and forward spread
Inner corner of two steering wheels when turning β And outer corner α Difference β-α It is called forward exhibition. In order to produce forward spread, the steering mechanism is designed into trapezoid.

3. Steering system angular transmission ratio 1 Steering gear angular transmission ratio IW1:
The ratio of the steering wheel angle increment to the corresponding increment of the steering rocker arm angle. (2). Steering transmission ratio iw2:
The ratio of the angle increment of the steering rocker arm to the corresponding increment of the angle of the steering knuckle on the side where the steering wheel is located.
(3). Angular transmission ratio of steering system I: I = IW1 – I W2
The larger the angular transmission ratio of the steering system, the lighter the steering is. However, if the transmission ratio is too large, the steering control will not be sensitive enough.
4. Free stroke of steering wheel: the angular stroke of the steering wheel in the idling stage.
Excessive free travel: insensitive steering.
The free travel is too small: the road impact is large, and the driver is too nervous.
