@mhetmayur Normally, when you have Ackerman steering the track rod ends up rotating in the yaw axis. This makes it not work with rack and pinion, since the rack changes its angle in relation to the pinion.
@jwoodcr It works because his steering arms aren't fixed to the hubs. If you look at the diagrams in wikipedia's Ackerman steering article, you can see that the mechanism essentially forms a trapezoid. This guy's steering basically forms an irregular hexagon. That allows the rack to stay parallel with the axle. This way doesn't appear to be nearly as sturdy, however... you'd need to be able to hold the rack firmly in the right track.
@sirboze Thanks for that, I see now. The wheels connect to an arm which connects to a static rod at the front end and another arm (connected to the track rod) at the rear. The system I have known about simply connects the wheels to the slanted steering arms, creating (as you said) a trapezium/trapezoid. It is very difficult to notice the improvement shown in the video, but it is very important.
How do you get rack and pinion to work with true Ackerman?
