When the vehicle is relied on the right, the worm moves a little to the left, with the response of the wheels, pitman shaft sector, steering linkage, and turning of the worm to the ball nut. The movement requires the worm against the thrust bearing and causes the actuating lever and control valve links to move the control valve to the position shown in the figure. The fluid passage to the best turn cylinder is broadened, while flow to the left turn cylinder is made narrower.
EPS, or electric power steering is a bit simpler as the vehicle’s computer is responsible for easing the steering process. The EPS system is frequently geared up with a small electric motor that is either positioned at the base of the steering column or straight on the steering rack. Unlike the hydraulic system, EPS does not use the power of the engine, which increases fuel economy. When a motorist wants to turn, the computer is able to equate the turning of the steering wheel to an electric motor that assists in moving the rack and pinion backward and forward. Comparable to HPS, the electric system differs the level of sensitivity at greater speeds for increased safety. Since the only fluid that this system uses is in the rack and pinion, it is not a functional unit and does not require fluid flushes.
The flow of fluid from the pump is restricted and the pump pressure is built on the ideal side of the rack position, triggering the ball nut to proceed the best side. The fluid in the left turn power cylinder is forced to the pump reservoir through the return line. When the vehicle needs to take a left turn, the worm triggers the fluid to enter the left-turn power cylinder in greater quantities and empty the right-turn cylinder. This effect makes the rack piston and ball nut move in the left-turn direction.
Power steering is a system that decreases the chauffeur’s effort needed for steering to turn the steering wheel. With the help of power steering, it much easier for the vehicle to turn or maneuver. Technician will inspect the vehicle and offer a comprehensive explanation on what is needed to fix your vehicle’s steering problems. SCANIA 1353047 and even a tire balance might be all your vehicle needs to reduce the troubles in the power steering system.

The power steering unit is located at the lower end of the steering column in place of the usual standard steering gear. It is connected by two oil lines to the hydraulic pump mounted on the generator. The pump with a relief valve prevents excessive oil pressures. It includes a worm-and-ball bearing nut steering gear with a hydraulic rack piston centered along the worm shaft, which can help in moving the nut in any direction through hydraulic pressure. A reaction contact valve is linked to the worm shaft thrust bearing through a link and actuator lever. Any moment of the thrust bearing triggers the control valve to move which opens and closes the oil passage between the valve body and the real estate of the gear and pinion assembly.
