Title Design of Four-Wheel Steering System
Abstract
This paper studies the basic structure and working principle of the vehicle
four-wheel steering system, and electronically controlled four-wheel
steering system is briefly analyzed. As a theoretical basis, design a car
with four-wheel steering system, including the design and calculation of
the front-wheel steering device and rear-wheel steering actuator.
Four-wheel steering system uses a four-wheel steering controller to
collect the sensor input signal, by processing the signal, and determines
the corner of the rear-wheel required size and direction of the control
actuator after completing the turn. This system can improve steering
flexibility and high-speed handling and stability, make the car faster
steering response, and improve steering capability and the straight-line
driving stability. The front-wheel steering device is the basis of
four-wheel steering parts, using motor power rack and pinion steering. The
rear-wheel steering actuator drives the rear wheels. Design of front-wheel
steering device and rear-wheel steering actuator provides the foundation
of the overall design. Keywords four-wheel steering system, electronically controlled
four-wheel steering system, electric power steering system, rear-wheel
steering actuator 目 录
