Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
A Hydraulic Power Steering (HPS) uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. Electric Power Steering (EPS) is more efficient than hydraulic power-steering, since the electric power-steering motor only needs to provide assistance when the steering wheel is turned, whereas the ...
Active steering describes a type of power electric variable gear ratio power steering technology introduced by BMW in 2003 first appearing on the redesigned 5 Series which varies the degree that the wheels turn in response to the steering wheel. At lower speeds, this technology reduces the amount that the steering wheel must be turned ...
Dynamic steering response (DSR) is a vehicle safety and advanced power steering system that can counteract unstable or difficult steering that may be caused by external forces such as strong crosswinds or uneven roads by giving proper steering assistance from the steering gear. [1]
Hydrosteer was the name given by George Kent Ltd and Cam Gears Limited through Hydrosteer Limited [1] of Luton, England, to its automotive power steering system. Initially Hydrosteer manufactured the Ross-Link system for commercial vehicles from 1953 under licence from Ross Gear and Tool of U.S.A. [2] Their own product available from 1961 was based on a cam and peg system and was characterised ...
Compare this with a conventional power steering system, which relies on the flexing of a strong spring to control the valve. The steering rack is almost conventional. As with a normal power-assisted steering setup, there is a rack-and-pinion, and a stepped hydraulic ram with a dividing plate (the piston) in the middle.
A Banjo steering wheel was an option in early automobiles. [26] They predate power steering. The wire spokes were a buffer or absorber between the driver's hands and the vibration transmitted from the road surfaces. Most were three- or four-spokes made of four or five wires in each spoke, hence the name "Banjo".
Applications that once were thought to require higher voltages, such as electrical power steering, were subsequently achieved with 12-volt systems. [1] In the late 2000s, 42-volt electrical components were used in only a few automotive applications, since incandescent light bulbs work well at 12 volts and switching of a 42-volt circuit is more ...
