In a valvetrain , pushrods are used to transfer reciprocating motion from the cam followers to a more distant part of a valvetrain, typically the rocker arms. The ends of the rack are linked to the steered wheels with tie rods. Rebound The motion of a wheel that extends the suspension. The opposite of jounce . A steering mechanism in which the steering shaft turns a worm gear that, in turn, causes a toothed metal block to move back and forth.
Ball bearings in a recirculating track reduce friction between the worm gear and the block.
As the block moves, its teeth rotate a gear connected to a steering arm, which then moves the steering linkage. The maximum recommended revolutions per minute for an engine. Some tachometers mark the redline with a colored sector. This dimension can be used to measure the amount of suspension deflection or the height of the body from the ground. Ride steer A generally undesirable condition in which a wheel steers slightly as its suspension compresses or extends.
