The motion of any vehicle is controlled with the help of a steering wheel. It indeed forms the base for the movement of the vehicle with the presence of components, linkages and joints. Interestingly, the automotive steering helps in directing the power from the engine to reach the wheels.
If you wish to learn about the direction control of an automobile, then gaining information about automotive steering is quite vital. Almost all steering variants are capable of controlling the angles at which the wheels move in two axes. Till date, the two mechanisms which have remained popular are the Rack & Pinion and the Recirculating Ball Steering.
Let us try to understand their importance as an automotive steering system, together with in-depth knowledge about their setup.
Rack & Pinion
It is the most common steering type across the automotive steering system market and is present in cars, SUVs and small trucks.
Functionality:
The moment we turn the steering wheel, it permits the gear to spin. The tie rod links to the steering arm that is connected to a spindle. To be precise, the whole motive of rack & pinion gear is to transform circular motion of the wheel into a linear motion. Hence, it allows the action of gear reduction, simplifying the movement of turning the wheels.
There is a subtype of this automotive steering wheel called as the variable ratio steering. It has several tooth pitch present at the centre to make steering less complex when the wheel comes close to the central position.
Re-circulating Ball/Steering Box
When it comes to heavy automobiles, you will always find a re-circulating ball steering system. The mechanism is quite simple which focuses on the rotation and turning of the rod. Hence, with the spinning of the wheel, the block tends to move. This motion instigates the movement of another gear that further creates motion in the Pitman arm. Furthermore, the ball bearings present in the threads re-circulate over the gear while it turns.
It is important to know everything about the steering system of your vehicle for smooth functioning. You can obviously get in touch with an expert, who will surely elaborate about their actual operation.
