Linear Actuator

Steering actually controls the direction of an automobile and it is really very important for safety and speed because it actually is the only control in your hand when you''re driving and if you look at old cars almost all of the weight was controlled by steering and it was very simple. Moreover, automobiles of these days are equipped with very complex for engineers but are very comfortable for the drivers. Most commonly steering systems are rack & opinion and re-circulating ball steering systems. In the rack and pinion steering mechanism, the steering wheel turns the pinion gear which moves the rack from side to side. The rack is sort of a linear gear which meshes with the pinion. This movement applies steering torque to the pivots of the steered wheels through the tie rods and the short lever steering arm. The re-circulating ball mechanism is found in older vehicles and is a variation on the older worm and sector design; the steering column turns the screw which meshes with a gear causing it to rotate about its axis which also moves the pitman arm which is connected to the steering linkage.
