INTRODUCTION OF PERFORMANCE

The steering force of the steering wheel can be decreased. Power can be felt obviously,
especially when the vehicle turns on spot or turns with great corner at low-speed.
The steering sensitivity is enhanced.
The impact of kickback from ground on the steering wheel is reduced.
In the case of tire burst, the sudden turning of the wheels can be effectively avoided. So the
security of driving can be improved.
The load on the steering wheel is permitted to increase, which can improve the freedom
motion of the general arrangement.
The power steering gear of the steering system of A15LHD is a standard feature, and the
mechanical steering gear is optional.
In fact, the power steering gear of A15LHD is based on the mechanical rack & pinion
steering gear and enhanced with a set of power mechanism which is composed of the engine
used as energy sources, the steering oil pump, the steering control valve, the power oil
cylinder and other components. Under the working condition, the power of the engine drives
the steering oil pump through the ribbed belt. The power steering fluid (ATF oil) is suck out
from the oil reservoir by the steering oil pump and formed pressure oil to get into the control
valve. After distributed by the control valve, the pressure oil enters the power cylinder to
push the working piston which is connected with one end of the steering rack. So the steering
power can be formed by the pressure oil through the working piston.
If the power steering system is in failure, the steering of the vehicle can be also completed by
the driver.
The optional mechanical steering gear is a rack & pinion steering gear which the power
source is the physical force (strength of the hand) of the driver. All the dynamic components
are mechanical.
