Theory
Automobile steering gear, also known as steering gear, power steering gear, is the most important part of the automobile steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission.
Steering gear type
Commonly used are rack and pinion type, worm crank pin type and
recirculating ball type.
1) Rack and pinion steering gear: It is one of the most common
steering gears. Its basic structure is a pair of pinions and racks
that mesh with each other. When the steering shaft drives the
pinion to rotate, the rack moves in a straight line. Sometimes, the
tie rod is directly driven by the rack to turn the steering wheel.
Therefore, this is the simplest type of steering gear. Its
advantages are simple structure, low cost, sensitive steering,
small size, and can directly drive the tie rod. It is widely used
in automobiles.
2) Worm-crank pin steering gear: It is a steering gear with a worm
as the driving part and a crank pin as the driven part. The worm
has a trapezoidal thread, the finger-shaped conical finger pin is
supported on the crank with a bearing, and the crank is integrated
with the steering rocker arm shaft. When turning, the worm is
rotated by the steering wheel, and the tapered pin embedded in the
spiral groove of the worm rotates while making a circular motion
around the steering rocker arm shaft, thereby driving the crank and
the steering vertical arm to swing, and then turning the steering
through the steering transmission mechanism. Wheel deflection. This
kind of steering gear is usually used in trucks with large steering
forces.
3) Recirculating ball steering gear: Recirculating ball power
steering system [2] The main structure is composed of two parts:
the mechanical part and the hydraulic part. The mechanical part is
composed of a shell, a side cover, an upper cover, a lower cover, a
recirculating ball screw, a rack nut, a rotary valve spool, and a
sector gear shaft. There are two pairs of transmission pairs: one
pair is a screw rod and a nut, and the other pair is a rack, a
tooth fan or a sector gear shaft. A cyclically rolling steel ball
is installed between the screw and the rack nut to change the
sliding friction into rolling friction, thereby improving the
transmission efficiency. The advantages of this type of steering
gear are that it is easy to operate, less abraded, and has a long
life. The disadvantage is that the structure is complex, the cost
is high, and the steering sensitivity is not as good as the rack
and pinion type.
