A radius rod (also called a radius arm, torque arm, torque spring, and torsion bar) is a suspension link intended to control wheel motion in the longitudinal (fore-aft) direction. The link is connected (with a rubber or solid bushing ) on one end to the wheel carrier or axle , on the other to the chassis or unibody of the vehicle.
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a ...
Despite the drawbacks, the MacPherson strut set-up is still used on some high performance cars, because they tend to have relatively small suspension travel, and so do not have the same kinematic problems. Up until the 1989 model year (964), Porsche 911 used a similar strut design that did not have coil springs, using torsion bar suspension ...
A strut bar, strut brace, or strut tower brace (STB) is an automotive suspension accessory on a monocoque or unibody chassis to provide extra stiffness between the strut towers. With a MacPherson strut suspension system where the spring and shock absorber combine in one suspension unit, which also replaces the upper control arm, the entire ...
Sparco S.p.A. is an Italian auto part and accessory company headquartered in Volpiano near Turin [1] that specializes in producing items such as seats, steering wheels, harnesses, racewear and helmets. Sparco branded alloy wheels are produced under licence by OZ Group. They also sponsor many types of auto races including rallies and single-seaters.
In the latter case, the suspension can be called a multi-link, or dual-ball joint suspension. The four-bar linkage mechanism formed by the unequal arm lengths causes a change in the camber of the vehicle as it rolls, which helps to keep the contact patch square on the ground, increasing the ultimate cornering capacity of the vehicle. It also ...
Miniature oil-filled Coilover shock components for scale cars. A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
Automotive suspension design is an aspect of automotive engineering, concerned with designing the suspension for cars and trucks. Suspension design for other vehicles is similar, though the process may not be as well established. The process entails Selecting appropriate vehicle level targets; Selecting a system architecture
