Essay - Power Steering After Years of Work on Improving General Steering...

Power steering

After years of work on improving general ***** apparati as a Pierce-Arrow truck engineer, Francis W. Davis developed and improved the first commercial examples of power steering systems (*****atson 2006). Davis patented ***** steering in 1932. He w***** working for General Motors' Cadillac branch (Watson *****). Prior to acquiring the patent, power steering systems were used mainly on large-scale manufacturing vehicles. Power steering made turning the steering wheels on fully loaded trucks tremendously easier, *****reby increasing worker productivity and manufacturing profitability. Watson (2006) notes that one coal company driver "could turn the wheel on his fully loaded truck with two fingers."

***** steering has dramatically changed society in the twentieth century just as the computer mouse *****: by ***** ease of c*****sumer access ***** complex mach*****es. Just as the ***** is an input device ***** computers, ***** steering is an input device for automobiles. Both the mouse ********** power ***** enable the end-user to customize his or her experience and enjoy using technology. As power steering became more widely ***** on commercial vehicles, a gre*****ter number of consumers found driving to be an enjoyable activity. The Chrysler Corporation ***** put a hydraulic steering system called Hydraguide. Similar to Davis' power steering on a commercial automobile in 1951, Hydraguide effectively *****passed the original patent while *****ing based ***** the same basic ***** steering principles. The French manufacturer Citro n also developed its ow***** hydraulic ***** system kn*****n as "Direction a rappel asservi," or DIRAVI. Power steering soon became commonplace on manufactured ***** cars ***** was ubiquitous by the end of the ***** century.

Power steering is based on hydraulics and so fluid is necessary to power the ***** rack-and-pinion steering system. A rotary valve is attached ***** steering gear driven by a pump, belt and pulley; the entire ***** ***** al***** composed of "retractable vanes" spinning inside an "oval chamber," (Nice nd). ***** hydraulic fluid levels vary depending on engine speed, regulating pressure and providing a safe and optimally comf*****table ***** experience. Power steering is usually engaged *****ly when the driver must exert extra force or torque such as during a turn. Otherw*****e, during long stretches of str*****ight roads, power steering is not necessary.

***** used on almost all late twentieth-century commercial *****, power steering systems have ***** changed substantially in their basic principles since they were first ***** as hydraulic systems in the middle of the twentieth century. Recently power steer*****g systems have ***** dramatically. ***** (nd) notes that power steering does consume fuel and so automobile ********** have been striving to make ***** hydraulic ***** ***** efficient. Electronic controls would "eliminate the mechanical connection between the steering wheel and the *****," (Nice nd). Essentially, an electronic power steering system would feel more like a computer gaming wheel than a traditional car wheel (Nice *****). General Motor's Hy-Wire system is an emerging example of electronic "drive ***** wire" ***** steering systems (Nice nd).

***** steering has not changed society for better or ***** worse. Some positive effects *****
