Steering is the term for the collection of links, gears and other things are all as a vehicle to follow a desired course. The concept is similar to the trucks and cars. The biggest difference between the steering system for an 18-wheeler is that it is much less sensitive than a car and much more difficult.
Modern cars and trucks with rack and pinion steering mechanisms. In this type of system, steering wheel, the pinion. The pinion is responsible forMoving the rack. The equipment rack is linear, with the pinion, converting circular motion into linear motion along the transverse axis of the vehicle (sideways movement). This motion applies steering torque to the steering wheel boss with ties and a short lever arm called the tiller.
Car Pa System
Rack and pinion design has the great advantage of a high degree of direct feedback and steering "feel". In addition, it usually takes no play or slack. The largestThe disadvantage of this system is that the steering rack and pinion system is not adjustable. This means that if the steering wheel and develop wear lash, the only way to solve the problem completely replaced the system.
Old systems with the steering ball. This system is still found on trucks and commercial vehicles. This is a variant of the design even older worm and sector. The steering column has a large screw or "worm", which mesh with an area ofTransmission. This leads to rotate around its axis as the screw is rotated. An arm is along the axis of the sector, which connects the steering column lever is moved. The pitman arm is connected to the steering linkage and check the wheels.
The ball version of the device reduces the friction significantly from large ball bearings between the teeth of the screw and the screw. The balls get out of the two pieces in a channel inside the box that connects them withthe other end of the device and are allocated.
The ball screw mechanism has the advantage of much greater mechanical advantage. This has done more, heavy vehicles. With the universal adoption of power steering, but this is no longer so important. The design is a ball or whip significant "blind spots" in the center. This means that when the wheel is centered, one minute, turn the steering wheel in either direction does not movethe rower.
