Linear Motion Systems
Advancement in field of Mechanical science has brought about revolution in automobile industry. New models of famous brands are designed these days with respect to care and comfort of all the passengers including driver. Scientists have point of view that more advancement are for mankind in order to provide more ease and relief from fatigue of the journey. They''re working on many projects for the benefits of people having medical problems as well.
Motion in a straight line is called linear motion. It can be constant and variable but its relationship with time, velocity and acceleration configure its type. That''s why it can be elaborated in its true sense through tools of mathematics. Linear speed of an automobile is considered the fastest possible that a specific automobile can experience. Various forms of energy such as gasoline, heating oil and diesel are used in mechanical systems of almost all automobiles. Depends on the variety of power transmission system these sources of energy are converted into mechanical energy. Linear motion is the fastest type of motion because it is straight and faces very little resistance. Mechanical propulsion system actually governs the assembly lines in automobiles.
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.
In a nutshell,We may say that linear motion of an automobile is fastest applications and steering mechanism control all the motion of your vehicle.
