In addition, the steering effort should build as the cornering forces at the steered wheels increase. Finally, the friction built into the steering mechanism should be small in comparison with the handling-related steering forces. The relationship between yaw and the steering wheel's position and effort. All three should be proportional and should build up smoothly. The group of design variables outside the steering mechanism that affect steering behavior, including camber, caster, linkage arrangement, ride steer, scrub radius, toe-in, and trail.
Power steering is essential to make large, heavy vehicles manageable.
Small vehicles often do not require power steering. Steering, Rack and Pinion A common steering type. The steering wheel is connected to a pinion gear that meshes with a rack, or linear gear. As the pinion rotates, the rack moves side to side, this moves the steering linkage, causing the wheels to pivot left or right. A subjective term that combines steering feel and steering gain.
