You’ll surely love to know about the commonly used power steering technologies. This slide reflects info about hydraulic power steering technology and electric power steering technology. See here their components, working process and how the latest technology differs from the traditional power steering system.
11. HPS are designed to assist the
operation of the rack bar by
generating oil pressure in the pump
12. The internal cavity is divided into
two chambers by a sealed piston
attached to the rack
13. Applying pressurized hydraulic
fluid to one side of the piston while
allowing fluid to return from the
other side to a reservoir provides
steering assistance.
14. A valve attached to the pinion gear
controls the hydraulic fluid flow and
helps to turns the wheels in the
required direction
21. EPS works with the help of an
electric motor and a control unit
having some sensors .
22. The electric motor mounted to the
side of the rack rotates a steering
gear with an applied force that
reduces the torque required from
the driver.
23. The torque sensor attached to the
pinion shaft signals a control
computer when to provide
assistance
