The scrub radius is the distance at the road surface between the tire center line and the SAI line extended downward through the steering axis. The line through the steering axis creates a pivot point around which the tire turns. If these lines intersect at the road surface, a zero scrub radius would be present.
A lower steering ratio means that the steering wheel is turned less to get the wheels turning, but it will be harder to turn the steering wheel. Larger and heavier vehicles will often have a higher steering ratio, which will make the steering wheel easier to turn. If a truck had a low steering ratio, it would be very hard to turn the steering ...
The steering pivot points [clarification needed] are joined by a rigid bar called the tie rod, which can also be part of the steering mechanism, in the form of a rack and pinion for instance. With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point.
Introduced in 2005, the Kenworth 963 is the largest truck ever mass-produced by Kenworth (replacing the 1958-2004 953, the final vehicle of the 900-series). [6] Sharing (only) its cab with the W900, the 963 is a 6x6 vehicle developed exclusively for off-road heavy-haul use (primarily for desert oilfields), with the ability to pull up to 500,000 ...
The recirculating ball steering mechanism contains a worm gear inside a block with a threaded hole in it; this block has gear teeth cut into the outside to engage the sector shaft (also called a sector gear) which moves the Pitman arm. The steering wheel connects to a shaft, which rotates the worm gear inside of the block.
Kenworth marked several firsts in truck production; the company introduced a raised-roof sleeper cab, and the first heavy-duty truck with an aerodynamically optimized body design. [3] The Kenworth W900 has been produced continuously since 1961, serving as one of the longest production runs of any vehicle in automotive history. The K100 was also ...

The Kenworth T600 is a model line of conventional-cab trucks that were produced by the American truck manufacturer Kenworth from 1984 to 2007. [ 1 ] [ 2 ] Distinguished by its aerodynamic sloped hood, the T600 was a Class 8 truck , typically sold in semitractor configuration.
