Of similar construction to a hydraulic shock absorber the strut used the motion of the suspension travelling over bumps to pump itself back up to a pre-set height. It was sufficiently powerful to regain up to 85% of normal ride height with a full load over the rear axle, and had the advantage of requiring no external power source or a dedicated ...
Shock absorbers are an important part of car suspension designed to increase comfort, stability and overall safety. The shock absorber, produced with precision and engineering skills, has many important features. The most common type is a hydraulic shock absorber, which usually includes a piston, a cylinder, and an oil-filled chamber.
Shock absorbers damp out the (otherwise simple harmonic) motions of a vehicle up and down on its springs. They must also damp out much of the wheel bounce when the unsprung weight of a wheel, hub, axle, and sometimes brakes and the differential bounces up and down on the springiness of a tire.
1968 BMW R60US with conventional telescopic fork Telescopic fork in upside down design, with stanchions at the bottom.. Conventional telescopic forks invariably have a pair of fork tubes, or "stanchions", at the top, clamped to a triple tree (also called a triple clamp or a yoke), and the sliders are at the bottom, attached to the front wheel spindle.
De Dion suspension characteristics: Camber change on one-sided bumps, none on rebound. The de Dion tube is shown in blue. The differential (yellow) is connected directly to the chassis (orange). Universal joints are shown in green. De Dion rear axle. A de Dion axle is a form of non-independent automobile suspension
All mechanical systems in the real world contain some amount of damping. Damping dissipates energy in the system, which reduces the vibration level which is transmitted at the natural frequency. The fluid in automotive shock absorbers is a kind of damper, as is the inherent damping in elastomeric (rubber) engine mounts.
In mechanics and physics, shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity).
