Steering Gear Working Principle

Steering Gear Working Principle

The steering gear, commonly known as the steering wheel, is the most important part of the automobile used for the steering function, and an important guarantee of the safety of automobile driving.

Rack and pinion steering gear

It is one of the most common steering gears. Its basic structure is a pair of mutual meshing pinion and rack. When the steering shaft drives the pinion gear to rotate, the rack will do linear motion. Sometimes, the rack is used to directly drive the crossbar, which can make the steering wheel steering.

Circulating ball steering

The steering screw rotates, the force is transmitted to the nut through the steel ball, the nut moves along the axis, the nut meshes with the sector gears, the straight-line motion becomes rotary motion again, making the linkage arm shake, the linkage arm makes the linkage rod and the cross tie rod to do a straight-line motion, change the wheel steering gear is commonly known as the steering machine, is the most important parts of the car used for steering function, is an important guarantee of the safety of automobile driving. It is the most important part for steering function of the car, and also the important guarantee for the safety of automobile traveling.

Worm crank finger pin steering

Worm crank finger pin steering gear transmission vice (as follows) to the steering worm 3 as the active part, the follower is mounted on the end of the rocker arm shaft 1 crank finger pins 2. steering worm rotates, with which engages the finger pins that is the axis of the rocker arm around the axis of the arc of the movement, and drive the rocker arm rotation. The steering wheel is then deflected by the steering transmission mechanism.

Hydraulic Integral Power Steering

When steering, the driver turns the steering wheel, driving the steering shaft and gears, so that the distribution valve is in the corresponding working position with a certain direction of turn, the steering power cylinder in the corresponding working chamber and the return pipeline disconnected from the impeller pump output pipeline, the other chamber is still through the return pipeline. Ground steering resistance is transmitted to the piston rod with rack and pinion by the horizontal tie rod, forming a much higher pipeline resistance than the throttle resistance of the steering control valve. So the impeller pump output pressure rises sharply. High-pressure liquid through the control valve into the side of the power cylinder piston, push the piston, and then push the rack to play the role of force.
