Pro Tip: ACKERMANN
HTML-код
- Опубликовано: 30 ноя 2015
- Ackermann is a finer front-end adjustment that can change the angle of your steering at which it opens and closes by changing the position of the tie-rods on the steering shaft. Justin from COMPKART shows you how to change your Ackermann and why you would want to. Full story can be found here: kart360.com/features/pro-tip-a...

Those Comp Karts are so beautiful wow...
Has anyone, besides Emmick in the 70s, ever tried true Ackerman steering principle in the front end of a kart chassis? This is accomplished by connecting both steering arms with a single tie rod and installing another tie rod from the Pitman arm to one of the steering arms. This way, if the steering arms point to the center of the axle, you will achieve a gradual and linear increase in the amount of toe-out as the wheel is turned. Remember that the purpose of the Ackerman steering principle is to have the front wheels track about a radius equal to the circle the kart is negotiating. In other words, the radius of the turn should be ( theoretically and not necessarily always) perpendicular to the front wheels to track around the turn without creating any scrub from the front tires. The current front end set up on a kart causes the front wheels to toe out at a non-linear rate versus one that proper Ackerman steering effect would create.
I agree ! " The current front end set up on a kart causes the front wheels to toe out at a non-linear rate versus one that proper Ackerman steering effect would create."
Without a tie rod adjustment, this is true, toe out happens.
Ackerman angle change happens with a change of angle of the spindle arm tie rod location, and is influenced by camber and caster while turning.
Dirt oval karts run a left Ackerman
you two did more to describe "ackerman" to me than watching 30-40 minutes of youtube uploads....i am building a recumbent trike and those guys simply cannot explain it. thankyou
That is a pretty interesting way to get ‘true’ Ackerman. Wonder why that didn’t stick around? Are you the same Jean Genibrel who wrote the Yamaha kt100 blueprint bible? I read that thing like 50 times.... Learned a ton! (Just always wished the pictures were clearer!). You should come out with one on the KA100, the X30, and even the LO206... I know those don’t really get blueprinted like a Yamaha, but there are still so many good things to learn from a book like that KT100 book.
Great video. I can see how the change you show adds/removes sensitivity on the wheel, what I don't see is how this has anything to do with Ackermann. I thought the main, and arguably the only significant, component to change Ackermann is the angle of the tie rod mount to the centerline of the axle - am I mistaken?
It would be great if you could do a video on the relationship between spindle selection and the resulting ideal steering angles based on average track turn radius and estimated slip.
I think I would rather watch your videos on these subjects! lol
International Precision Engineering, sir i need your help i am building a gokart, and my track width is 46inch and wheel base is 39inchs, i need to find the suitable tripod length and base for achermann angle so that my percentage error will be less plszz reply
International Precision Engineering, i need to keep the tirod inclination below 7degree
I think there has been a mix up between Akerman vs response. The adjustment you show only apears to effect response or "gain" for lack of a better term. To change Ackerman at the column, you would need mounting options on the column that would increase the gap between the rod ends.......no?
I agree, this adjustment has nothing to do with Ackerman, and will have no effect on handling. It will change the amount the tires turn for a given amount of steering wheel input and that's all.
@Brisdad53 So does how the adjustment you showed cause the inside wheel to turn at a greater angle than the outside wheel from the previous setting? It appears to me both wheels will turn the same amount for a given steering wheel input, in both of your settings. The Ackermann angle is determined by plotting an imaginary line from the wheel's pivot point through the steering rod end connection. See the diagram from the Wikipedia page you referenced, its the diagram on the right hand side under the heading "Design and choice of geometry". Neutral Ackermann would be if those lines intersected in the middle of the rear axle. I can't see how the adjustment you made would change the locations of the wheel pivot point and where the steering arm connects.
which steering system did you use ??
Do you have a CAD model for this steering???
What is that kit call
So what is important here...? the guys face or the actual adjustment? And what does this have to do with ackermann? I didn't think ackermann was responsiveness...but of course I could be wrong. In fact I hope I am since he is the one supposedly 'teaching' us.
wait you can get some Ackermann? i remember there being Ackermann or no Ackermann not some Ackermann.
Justin you forgot to mention that you need to reset the toe on the alignment.
@Brisdad53 Wrong, with the adjustment you made the toe will change the Ackermann will not. Your adjustment changes the length from the steering shaft input to the steering arm connection point, that will absolutely change the toe. Here's a pretty good video that will help you understand Ackermann. ruclips.net/video/_mOwsORl7e8/видео.html
Wow, this has zero to do with ackerman. I'm shocked a so called reputable kart company does not have a clue.
Ackerman is measured from the centerline of the rear axle to the kingpins. The outer tie rod pivot mount point should fall on the imaginary line between the kingpin and the rear axle centerline.....PERIOD.
A little mistake here. Lower hole - less Ackerman. Higher hole - more Ackerman.
Do u have any reference?
Alexander Kramarsky , your wrong .
"Pro Tip??" Is he kidding? Ackermann has to do with the relationship of the spindle steering arm, to the kingpin and the center of the rear axle. It is responsible for the inner wheel turning a tighter radius than the outer. All he was adjusting was the steering "quickness". And the alignment would have to be re-set.
If you are looking for a "Pro shop", you better keep on looking.
1000 view ;p
