9-1 Electric power steering system
INTRODUCTION
Our UTV is equipped with Electric Power
Steering System (EPS). To keep reliability of
EPS during operation, please correctly use
EPS system according to the following
descriptions and keep daily inspection and
maintenance.
This chapter also provides important
information to safely use EPS system. If you
encounter any problem during operation or
maintenance, please feel free to consult your
local dealer.
ADVANTAGES OF EPS SYSTEM:
1） High efficiency. Traditional hydraulic
power steering system is connected by
mechanical and hydraulic, and it is of low
efficiency, usually only 60%-70%.
However, EPS system is connected by
mechanical and electric motor and it is
much high efficiency with up to 90%.
2） Less energy consumption. In practical
driving process of UTV, time in steering
condition is only 5% among the total
travelling time. As to hydraulic power
steering system, as long as the engine is
running, the hydraulic pump is always in
working condition, and fuel consumption
will increase 4%-6%. However, EPS
system starts the motor, only when it
needs steering, to generate power
without increasing fuel consumption.
3） The power characteristics of EPS system
can be controlled by software, so that
UTV can be satisfied with power steering
