The Orbitrol is used principally for
hydrostatic power steering systems of industrial vehicles
, construction vehicles and boats, but it can be used for some servo-type applications or any applications where visual positioning are required.
How does a steering orbital work?
All of Trail-Gear’s orbitals (steering control valves) have a built in return-to-center function. This means that
when the driver releases the wheel the tires will automatically return to the center position
. This is a convenient feature that allows for slow rock crawling or driving at higher speeds.
What is a steering Orbitrol?
This
rotary slide valve is used for hydrostatic steering
. When the steering wheel is turned, the steering unit dispenses a quantity of oil to the right or left which is proportional to the turning of the steering wheel.
What is a steering control unit?
Based on the steering signal from the torque sensor, the steering control unit
calculates the optimal steering support and sends the information to the electric motor to provide the necessary assist
. … The steering control unit is also the interface to other control units of the vehicle.
How does a hand metering unit work?
The hand metering unit (HMU) is a small, hand operated hydraulic pump. Pressure oil from the main hydraulic pump is sent to the inlet (4) where
it stopped when the unit is
in the neutral position. … The oil that is pumped by the HMU is sent through connecting lines to the steering valve.
What is full hydro steering?
A full hydro (hydraulic) steering system is
one in which no mechanical linkage connects the steering wheel to the steering knuckles
. The power steering pump pushes fluid through hydraulic hoses into and out of a steering cylinder that then turns the wheels.
How does a hydraulic steering work?
As its name suggests, hydraulic power steering uses the force of pressurized hydraulic fluid to assist with the steering,
working whenever the driver turns the steering wheel
. The fluid is pressurized by a pump, which gets its power via a belt attached to the engine.
How does a hydraulic steering motor work?
Hydraulic power steering uses
fluid to intensify the force applied to turn your front wheels
. The hydraulic fluid is pressurized by a pump driven off the engine, which provides hydraulic pressure to the steering system.
How does a priority valve work?
Priority valves are used
to provide a hydraulic function in a load sensing system with a priority flow
.In principle, they operate like a 3-way flow control valve that always supplies the actuator that has priority with the required flow rate, and passes the remaining flow to other actuators.
What are hydraulics uses?
Hydraulics are often used for
moving parts of mechanical systems that need to lift or push heavy objects
. The landing gear in an aircraft use several hydraulic cylinders to move the wheels into place and to cushion the aircraft’s landing.
Where is the power steering control module?
Also, be aware that most power steering control modules will likely be mounted on
or near the steering column or the steering gear
.
How do you know when electric power steering is bad?
- Difficulty turning the wheel. One of the most common signs you have steering wheel failure is that it is hard to turn the steering wheel. …
- Pulsating or vibrating steering wheel. This symptom is usually experienced when the car is idling. …
- Low Power Steering Fluid.
What does a steering ECU do?
The EPS electronic control unit (ECU)
calculates the assisting power needed based on the torque being applied to the steering wheel by the driver, the steering wheel position and the vehicle’s speed
. The EPS motor rotates a steering gear with an applied force that reduces the torque required from the driver.
What is a hand metering unit?
Take a look at the hand metering unit valve, also known as an orbitrol valve. It’s
a type of servo valve that quickly closes off its own flow after sending out the correct volume of fluid to
the steering cylinders.
What is a steering valve?
The Steering Control Valve is a part of the hydraulic power steering system. It
is used to control the flow of fluid into the steering system
. … When the car is driving on a straight road, the steering valve remains in position and the fluid flows through the system and into the reservoir.
What is Orbital hydraulic motor?
Orbital hydraulic motor is a
kind of small low speed and high torque hydraulic motor with one shaft flow distribution and inlaid stator and rotor pair
. … 3.It can be used in series or parallel in hydraulic system.
