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 ...
The recirculating ball steering mechanism contains a worm gear inside a block with a threaded hole in it; this block has gear teeth cut into the outside to engage the sector shaft (also called a sector gear) which moves the Pitman arm. The steering wheel connects to a shaft, which rotates the worm gear inside of the block.
Active steering describes a steering system for a vehicle in which the relationship between the driver’s steer inputs and the angle of the steered road wheels may be continuously and intelligently altered. Whilst active steering systems may be found in agricultural equipment and heavy plant, this article concentrates on the application of ...
The steering linkage which connects the steering gearbox to the front wheels consists of a number of rods. These rods are connected with a socket arrangement similar to a ball joint, called a tie rod end, allowing the linkage to move back and forth freely so that the steering effort will not interfere with the vehicles up-and-down motion as the ...

In 1898, steering wheels became a standard feature of Panhard et Levassor cars. They were introduced in the U.S. by Packard in 1899, and by 1908 were on most models. [1] Power steering helps drivers steer by augmenting the driver's steering effort. Power steering has used hydraulics to reduce a driver's steering effort
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.
Power steering affords the driver reduced effort to steer the car. Modern power steering has almost universally relied on a hydraulic system, although electrical systems are steadily replacing this technology. Mechanical power steering systems were introduced, such as on 1953 Studebakers. [20] However, hydraulically assisted systems have prevailed.
