Shock-mitigating suspension seats are designed to reduce the severity of vibration and mechanical shock. These seats are used in vehicles that operate in high exposure environments, such as high-speed watercraft , military platforms , construction , forestry and agricultural vehicles , and industrial trucks (such as fork lifts ).
Watt's linkage automobile suspension Watt's linkage train suspension. Watt's linkage is used in the rear axle of some car suspensions as an improvement over the Panhard rod, which was designed in the early twentieth century. Both methods are intended to prevent relative sideways motion between the axle and body of the car.
Three similar shock mounts support the seat. A similar idea, also known as a shock mount, is found in furniture design, introduced by Charles and Ray Eames. It provides some shock absorption and operates as a living hinge, allowing the seat back to pivot. Shock mounts are also sometimes used in bicycle saddles, [4] handlebars and chassis.
The modern racing sulky has shafts that extend in a continuous bow behind the driver's seat, with wire-spoked "bike" wheels and inflated tyres. [1] [2] A sulky is frequently called a "bike". Historically, sulkies were built for trotting matches and made from wood with very tall wheels and almost no body, just a simple frame supporting a single ...
A short long arms suspension (SLA) is also known as an unequal-length double wishbone suspension. The upper arm is typically an A-arm and is shorter than the lower link, which is an A-arm or an L-arm, or sometimes a pair of tension/compression arms. In the latter case, the suspension can be called a multi-link, or dual-ball joint suspension.
Land Rover developed a self-levelling rear suspension using the "Boge Hydromat" self-energising hydraulic strut. [13] 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 ...
The hydraulic shock absorbers used on the rear suspensions of motorcycles are essentially the same as those used in other vehicle applications. Motorcycle shocks do differ slightly in that they nearly always use a coil-over spring. In other words, the spring for the rear suspension is a coil spring that is installed over, or around, the shock.
A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [ 1 ] [ 2 ] [ 3 ] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet.
