Most control arms form the lower link of a suspension. Control arms play a crucial role in the suspension system of a vehicle. They help to keep the wheels aligned and maintain proper tire contact with the road, which is essential for safety and stability. [1] The inboard (chassis) end of a control arm is attached by a single pivot, usually a ...
A rubber bushing may also be described as a flexible mounting or antivibration mounting. These bushings often take the form of an annular cylinder of flexible material inside a metallic casing or outer tube. They might also feature an internal crush tube which protects the bushing from being crushed by the fixings which hold it onto a threaded ...
Camber angle could generally be adjusted by moving both inner pivots of either the upper or lower control arm inwards or outwards by an exactly equal amount. But compliance of the control arm inner pivots, typically due to the use of elastomeric bearings, would again cause the trunnions to be stressed.
The crossbeam and lower links maintain the correct toe angle of one wheel relative to the other, however due to the relative angles of the trailing radius arms, body roll results in the entire cross-beam and lower links pivoting slightly about the crossbeam's mounting points, thus inducing a small amount of passive rear wheel steering, which ...
In general it is difficult to improve the kinematics of a suspension using the bushings, but one example where it does work is the toe control bush used in Twist-beam rear suspensions. More generally, modern cars suspensions include a Noise, vibration, and harshness (NVH) bush. This is designed as the main path for the vibrations and forces ...
The front of the H attaches to the body via rubber bushings, and the rear of the H carries each stub-axle assembly, on each side of the car. The cross beam of the H holds the two trailing arms together, and provides the roll stiffness of the suspension, by twisting as the two trailing arms move vertically, relative to each other.
The camber control arm regulates the movement of the lower arm, so when the suspension reacts to a uneven road surface, the upper part of the upright pulls inward, causing the camber angle to change negatively. Note that the inclination of the strut body may be opposite to that of the MacPherson strut type.
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. Radius rods are ...
