Orientation Machine Introduction: Principle, Structure and Classification

First, the principle of direction machine
The direction machine is an important part of the car, and its main function is to convert the driver's direction instruction into the motion state of the tire. The principle of the direction machine can be simply summarized as: through the operation of the driver, a rotating torque is generated, so that the steering gear rotates, and then drives the front wheel to steer, so as to achieve the steering of the vehicle.
​
Second, the direction machine structure
The steering machine is composed of steering handwheel, steering gear, gear shaft, gear housing, gear, fork gear, tow rod, left and right linkage rod, etc. Among them, the steering handwheel is connected to the steering gear through the connecting rod. When the driver rotates the steering wheel, the steering gear will rotate, thereby driving the steering of the front wheel of the vehicle through the gear, fork gear and other components.

Three, direction machine classification
According to the different transmission power, steering machine can be divided into mechanical steering machine, hydraulic steering machine, electric power steering machine, electronic steering machine and so on. The mechanical direction machine is the most basic one, its principle and structure are relatively simple, and the control is relatively difficult. The hydraulic steering machine transmits power through the liquid, making the driver's control smoother. The electric power steering machine uses the power of the motor to assist the driver to control the direction of the vehicle, especially for urban driving. The electronic direction machine is a new type of direction machine that has appeared in recent years, which can sense the rotation force of the steering hand wheel through the sensor, so as to control the motor output appropriate power.

In short, the direction machine is an indispensable component of the car, its principle, structure and classification type is an important basis for our understanding of the vehicle steering principle.
