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 ...
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.
In sports cars, optimal camber change when turning, is more important. Wishbone and multi-link allow the engineer more control over the geometry, to arrive at the best compromise, than swing axle, MacPherson strut, or swinging arm do; however, the cost and space requirements may be greater.
Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. Struts may be vertically plumb or leaning (then called canted, raking, or angled) and may be straight or curved.
An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
This is commonly achieved via use of dampers and springs, providing downward forces on the wheels to counteract impact shocks. However, in push-rod suspension systems, this strut is mounted across the chassis, parallel to the ground, as opposed to the perpendicular system commonly used.
The oleo strut became commonly used for aviation purposes around the world. [3] By the twenty-first century, a wide range of different shock-absorbing struts were in use, but typically employ common principles, despite considerable variations in size, weight, and other characteristics. [15] [16]
A mono-tube coilover is a single piston and rod assembly in a damping case in which both compression and rebound occur. A larger mono-tube shock will be able to displace more hydraulic fluid, providing a more sensitive response to small suspension movements than twin-tube shocks. A twin-tube coilover is more complex than a mono-tube assembly.
