The working principle of the direction machine

The steering gear is a key component in the car steering system. Its main function is to convert the driver's steering operation (such as turning the steering wheel) into the steering action of the wheels. The working principle of the steering gear is usually based on the principle of gear transmission or rack transmission. The following is a detailed explanation of its working principle:

gear drive direction machine:
In a geared steering gear, the steering wheel is connected to a steering gear (usually a worm or sector gear) through a steering column.
When the driver turns the steering wheel, the steering gear will rotate accordingly, and the steering force will be transmitted to the steering tie rod through a series of gear meshes (such as worm and worm gear, sector gear and rack, etc.).
The steering tie rod further transmits the steering force to the steering knuckle of the wheel, causing the wheel to produce a steering action.
rack drive direction machine:
In a rack-driven steering gear, the steering wheel is connected to the rack (or steering rack) through the steering column.
When the driver turns the steering wheel, the rack moves along its length.
The moving rack is connected to the steering knuckle of the wheel through the steering tie rod, thereby pushing the wheel to produce a steering action.
