Invention Needed Actuated Tie Rod Steering Linkage 02 29 2012

Invention Needed Actuated Tie Rod Steering Linkage 02 29 2012
You only need the toe in for turning or initiating a turn.  When going straight the wheels should be straight.  The steering rack/gear could “cam” in on a turn so that it is differential.  The way it would work is that the outer wheel, in a turn, turns in at the 3 degree or 1 degree (whatever is specified) first before the other wheel turns at all.

In our modern age the front wheels should be constantly self-aligning in relation to miles per gallon and within a certain limiting factor of adjustment.

Actuated Tie Rod Steering Linkage could accomplish this feat.  A two section “Stop pegged limit” servo actuated or hydraulically actuated or adjusted tie rod.

It could be made of concentric fitted rod to pipe/rod.

Background:  When I did my own wheel alignment using a mechanical gauge I got 29 mpg on the highway.  That was on a 2001 model car.  Our new 2011 model of the same car only gets 21mpg on the highway.   So what could be the difference?

How I thought of this invention:  Last night I got home late from the gym and our garage door would not go down.  A garage door is works by sliding on rollers in tracks on each side.  The axles to both lower rollers had jarred from their inner axle races on both sides.  This may be due to unbalanced spring tension.  I ended up removing the lower axle/race plates and then the rollers with axle.  I drilled through the ends of the axles with a 1/8” bit and after I reinstalled them I put a washer on the outside end of the axle opposite the roller and held it in place with a  bent in cotter pin.  They can no longer come out of their races or axle holes.  This is how I thought of the tie rods that could be adjusted, but only to a point.  But anyway I looked at them and they looked like how you set the alignment on a car- camber in by 1.5 or 3% or whatever the specific manual says.  I have always wondered why steering should be camber in?  The reason they say is so that you can pull into a turn quicker.  That is all right, but what about mileage on the straight away?  Wouldn’t it make better sense if a wheel is turning straight and not cambered in on a straight away?  Wouldn’t a straight align wheel get better mileage and less tire wear?  In today’s modern age of computer control engine systems maybe the time has come to make the wheel and steering the way it should really be?  The system could also be made possible with a differential type steering gear.

It reminds me of the way the nose of the Concorde is actuated upon take off and landing.
