9L Front axle help

[TomasHubik]

Hi Guys!,

I'm trying to compose front axle for my new truckt and would like to move wheel as close to pivot as possible. I have problem with steering. When I use RACK it gous to bad angle which is imposible to use with gear (PIC2).

I can't put SERVO vertically (Not enought space PIC1

Hi Tomas,

I like this scale very much. Could you place a bigger size of your profile picture? I think that truck is in the same scale.

what you have there is ackermann steering. you should attach the wheels to this part If you want to keep the ackermann geometry, you should find another way to steer it.

[efferman]

is your servo in front of the axle or in the back of the axle? when it is in the back, the ackermann is on the wrong side. is the steering rack in front of the axle the pivot point of the steering rack has to be between wheel and wheel pivot point.

If you don't mind losing the Ackermann steering geometry, replace the steering arms with one of those light-grey 3-stud beams with 4 pins attached to them (like the short one you already have, but longer). Then change the rack to a slightly longer 9-stud one.
