Unlike a shock absorber, a strut has a reinforced body and stem. Struts are subjected to multidirectional loads, while a shock absorber only damps vibration, only receiving a load along its axis. Struts and shock absorbers have a different way of attachment. Shock absorbers are mounted through rubber or urethane bushings to the frame and ...
For both ends of the car this would include the type of spring, location of the spring, and location of the shock absorbers. For the front suspension the following need to be considered The type of suspension (MacPherson strut or double wishbone suspension) Type of steering actuator (rack and pinion or recirculating ball)
Oleo strut - design used in most large aircraft, with compressed gas and hydraulic fluid - conceptually similar to automobile Hydropneumatic suspension; Scrub radius; Short long arms suspension — also known as "unequal length A arm", one of the design parameters of double wishbone suspension; Strut bar — a part to make a suspension setup ...
The strut will usually carry both the coil spring, on which the body is suspended, and the shock absorber, which is usually in the form of a cartridge mounted within the strut (see coilover). The strut can also have the steering arm built into the lower outer portion. The whole assembly is very simple and can be pre-assembled into a unit.
The coilover combines a shock absorber and a spring in a single unit. A common form of automotive suspension strut in an automobile is the MacPherson strut. MacPherson struts are often purchased by the automakers in sets of four completed sub-assemblies: These can be mounted on the car bodies as part of the manufacturers' own assembly operations.
The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle , caster angle , toe pattern, roll center height, scrub radius , scuff ( mechanical abrasion ...
