Introduction
Automobile steering gear, also known as steering gear, steering
gear, is the most important element in the automobile steering
system. , And most of them are hydraulic energy (or pneumatic
energy) provided by an oil pump (or air compressor) driven by an
engine (or motor).
It has the ability to convert the mechanical energy of the output
part of the component (or motor) into pressure energy, and under
control, apply hydraulic or pneumatic forces in different
directions to an object in the steering transmission or steering
gear to assist in the lack of force throughout the entire process
The sensitive demand, the total power steering gear.
Theory
Electric motor power steering is when the driver moves the steering
wheel at the same time, the electric motor under it starts
The rack-and-pinion power steering is a hydraulic pump beside the
engine, and the engine drives the pump to work.
Electro-hydraulic assist is a combination of the first two, and it
is also the best steering assist device on the market today
The structure of the steering booster is very complicated and
cannot be repaired by ordinary people. If the maintenance is in
place, it is not easy to break. Note: 1. You should always check
the oil in the oil cup, and it should not be lower than the lower
limit of the oil dipstick. If the booster loses oil, the pressure
pump may be scrapped. Second, you need to change the oil regularly.
Third, you can't kill the direction. Fourth, try not to make
directions on the spot.
The power comes from the engine, and the truck has no other
power-assisted mode, only the hydraulic booster pump, which is
usually installed on the flywheel housing and driven by the
crankshaft. It is also installed in front of the engine and driven
by a belt, but this is generally modified.
Steering machine
Steering machine
The power steering system is composed of a set of power assist
devices on the basis of the mechanical steering system. The
steering oil pump 6 is installed on the engine and is driven by the
crankshaft through a belt and outputs hydraulic oil. The steering
oil tank 5 has oil inlet and outlet pipe joints, which are
respectively connected with the steering oil pump and the steering
control valve 2 through oil pipes. The steering control valve is
used to change the oil circuit. The mechanical steering gear and
the cylinder block form two left and right working chambers, which
are respectively connected by an oil passage and a steering control
valve.
When the car is driving straight, the steering control valve 2
connects the working fluid pumped by the steering oil pump 6 with
the oil tank, the steering oil pump is in an unloading state, and
the power steering device does not have a boosting effect. When the
car needs to turn to the right, the driver turns the steering wheel
to the right, and the steering control valve connects the working
fluid pumped by the steering oil pump to the R cavity, and connects
the L cavity to the oil tank. Under the action of oil pressure, The
piston moves downwards, and the left and right wheels are deflected
to the right through the transmission structure, thereby realizing
right steering. When turning to the left, the situation is
reversed.
