What is handling the configuration variable steering ratio?

1

what’s the use?

That is to adjust the steering gear ratio according to the vehicle speed and the steering angle, when the car is parked starts, the vehicle speed is low or the steering angle is large, providing a small steering gear ratio, and when the car at high speed or steering angle is small, to provide a large steering gear ratio, thereby improving the steering stability.

mechanical variable steering ratio

The main mechanical variable steering ratio by a “rack and pinion mechanism,” implemented by special machining process is not equal to the backlash rack attain, at a steering wheel, gear rack pitch is not equal nip, the steering ratio will change.

Electronic variable steering ratio

electronic steering than using a more complex mechanical structure, and the electronic system requires binding. Can better achieve “low-light sensitivity, high-speed steady heavy” demand.
