Electric power steering. More and more power steering systems found in modern cars and trucks are electric, not hydraulic. Electric power steering systems include various sensors, wires, and actuators (motors), any of which can fail, but luckily such failures are less common than failures of hydraulic components.
Power steering utilizes a hydraulic pump running off a belt driven by the engine, this pump enables a small amount of fluid to be under pressure. This pressure in turn assists the steering mechanism in directing the tires as you turn the steering wheel. The power steering system typically includes a pump, power steering fluid, a pressure hose assembly, a control valve and a return line. There are two basic types of power steering systems used on vehicles.
The Horst Link is a type of four-bar suspension. Leitner formed a mountain bike and research company, AMP research, that began building full-suspension mountain bikes. In 1990, AMP introduced the Horst link as a feature of a "fully independent linkage" rear suspension for mountain bikes.
For low speed sensitivity, the PDS is better because it is controlled strictly by the shock dampening without interference from the progressive link. For maintenance and durability, I think they are about even. The linkage shock is kind of a pain to get out of the bike, the top subframe bolts need to come out.
Shock absorbers are dampers that control suspension movement. Struts are usually a combination of a suspension support part and a shock absorber. Many vehicles have struts at all four wheels. Some have struts at two wheels with shock absorbers and separate suspension springs at the other two wheels. When struts or shock absorbers are worn out they no longer can control suspension movement, so ...
Since a coil spring occupies a relatively small space, it can be used in a variety of suspension designs including MacPherson strut, solid axle with trailing arms, independently sprung rear axle, or any SLA suspension system using a spring or coil-over shock absorber configuration.
Steering system — all types Every steering systems contains numerous linkages, some joints such as the tie rod ends mentioned above, and some sort of steering box, the mechanical device that converts rotation of the steering wheel into movement of the car’s wheels.
