help please with ackerman doesnt work

[dalton]

hello i have a few problems that i need advice on wtih my go kart im building .

i have my spindle arms line up with the center rear axle . however when i turn it seems the out side tire is slightly turning sharper totally reverse than ackerman.

and also when i turn it turns sharp inwards but doesnt turn sharp out wards at all.


any suggestions or advice ?

Umm- you have no componentry there... How do you know of the problem?
And FWIW- It's not the steering arms that must align with the strings- it's the holes for the rod ends.

thanks for the quick response

i have the angle set up so that the holes align , just n the picture the tires are turned a bit ,

but i have made a mock up of the steering components because im not sure what im going to do as far as it goes yet because it wasn't working , ( i do have longer tie rods just not pictured)

so this is the setup i used i thought the steering piece wasnt big enough so i made a new one wasnt the case

guys you may need to back me up on this one (or i could be just seeing thigs) but with the way the two tie rods attach (i think) there is going to be more movment in one of the tie rods... I would try attaching both tie rods to oe piviot point (see this pis shows how they both attach to one point) this is just an idea to try i could be wrong so dont take my word for it but thats what i am seeing

lookig at the pics i am preety sure this is your problem

Ding ding ding! Your absolutely correct. Dalton, you need to have both tie rods pivot from the same place.
