STEERING & SUSPENSION - SET
2(GRADED A+)
reaction force - ANSWERA force that acts in the opposite direction to another force.
rigid-axle coil-spring suspension - ANSWERA dead axle that uses a coil spring.
roll - ANSWERMovement of a vehicle around its x-axis (the imaginary line down the
center of the vehicle from front to back). It is commonly referred to as body roll or
lean; when cornering, the body will try to move to the outside of the corner against
the suspension.
scrub radius - ANSWERThe distance between two imaginary points on the road
surface--the point of center contact between the road surface and the tire, and the
intersecting point where the steering axis centerline and the tire centerline contact
the road surface.
shock absorber - ANSWERA device on a vehicle designed to absorb bumps and
jolts caused from driving on irregular surfaces and to dampen body movement.
short-/long-arm (SLA) suspension - ANSWERA type of control arm suspension
system that uses a short control arm on the top and a long control arm on the
bottom. This design ensures correct alignment angles when moving through bumps.
shroud - ANSWERA steel or plastic cover placed over the shock rod.
solid axle - ANSWERA single piece of steel that provides a simple means of
mounting the hub and wheel units. Also called beam axle or straight axle.
splined section - ANSWERA flat key made into a shaft to accommodate changes in
shaft length due to movement in wheel camber with suspension action.
torsional load - ANSWERA force that is applied by clamping one end of an object to
another object that is then twisted.
trim height - ANSWERThe amount of ground clearance a vehicle has, measured
from a point on the body or frame depending on the manufacturer. Also known as
ride height.
turning radius - ANSWERA measure of how small a circle the vehicle can turn
around when the steering wheel is turned to the limit.
universal joints - ANSWERJoints placed on each end of a driveshaft that help
compensate for movement of the rear end housing up and down.
