What is Electric Power Steering Rack and How it Works?
What is power rack steering? The steering rack is composed of a
rack enclosed with a steering pinion. It is connected to the
steering wheel through the set of shafts and U-joints. A power
steering rack utilizes an engine-driven pump to supply
high-pressure hydraulic fluid to the steering rack when the wheel
is turned.
Benefits of electronic steering gear
Pros #1: Improves fuel economy
A traditional hydraulic power steering uses a steering pump that is
driven by an engine belt.
The moment you start your car engine, the steering pump starts
running regardless whether you are turning the steering wheel or
not.
This drains your car engine power, which means you get less bang
for your petrol bill.
As opposed to the hydraulic power steering, an electric power
steering only activate when necessary.
When you turn, the sensors tells the ECU that you need help turning
the car. The ECU will then orders the motor to turn.
When you are not turning, the electric power steering parts will
just stay put.
Yes, you do need more electric power from your battery and your car
alternator now to keep these components powered up.
But cumulatively speaking, it’s a lot less wastage compared to the
old hydraulic way!
An electric power steering improves the fuel economy by up to 2%
compared to their hydraulic counterpart.
Pros #2: No more leaks and no more topping up steering fluids!
Because electric power steering no longer requires hydraulic to
provide the power assist, we can get rid of steering pump, hoses,
and steering fluid altogether. This takes away one common power
steering rack problem – fluid leaks!
Gone were the days that you have to top up steering fluids too.
Pros #3: Programmability – Limitless potential
As an electronic and computer-controlled device, we are not limited
by the nature of hydraulic systems.
Theoretically, we can use electronics to monitor everything and
help us make well-informed decisions. If we don’t like a certain
thing, we can fine tune them through programming.
