Chery A15 Maintenance Manual
Chapter Two: Steering System
A15 series’ steering system is equipped with standard power steering gear and optional mechanical steering gear. The power steering gear adopted by A15 series is actually a mechanical gear rack steering gear equipped with a power assisted device powered by engine and features parts including steering oil pump, steering control valve and power cylinder, etc. Working process: engine power drives steering oil pump through multi-wedge , and steering oil pump aspirates the power assistant oil in oil tank (ATF oil), and presses the oil into steering control valve, then the pressure oil distributed by control valve enters into power cylinder to actuate working piston. Since the working piston is connected with one end of steering rack, the pressure oil provides function of power-assisted steering through the working piston. In case the power steering gear fails, the driver shall still be able to complete the steering independently. Optional mechanical steering gear is a gear rack steering gear, which is powered by the driver’s physical energy (hand power), and the power is entirely transmitted by mechanical parts.
