jorgeopesi Posted October 14, 2012 Posted October 14, 2012 Because I enjoy doing the most difficult I always try to put the maximum steering angle in my MOCs but I think most of the time I put more than necessary and I waste time and complicate me without requiring, for this reason I like to know what different angles are used in vehicles such as trucks, cars, formula ones or what you can think, another big question I have is where is usually placed on the wheel the steering pivot, outside inside?. It would also be a good idea to collect here the various existing management or invented systems so people could clear doubts. Thank you. Quote
DLuders Posted October 14, 2012 Posted October 14, 2012 Have you seen George Staples' Ackermann Steering tutorial? Quote
jorgeopesi Posted October 14, 2012 Author Posted October 14, 2012 Very interesting so the angle depends on the distance between axes. Tutorials like this are great, to have a few around here would be great. Quote
Teo LEGO Technic Posted February 14, 2014 Posted February 14, 2014 The steering is usually slightly inside the wheel rhim. This helps stop 'bump steering' as Zblj so ably described earlier. It also allows steering in a tighter space. The best peice I know of in LEGO is an inverted 42009 tire with a CV joint. Hope this helps! Quote

The 8448 wheel is even better but there are few MOCs use them... Quote
DrJB Posted February 15, 2014 Posted February 15, 2014 You could try some multi-link suspensions ... a rather fascinating subject Quote
martinmalmo Posted February 15, 2014 Posted February 15, 2014 May I add question to this topic? I've also been frustrated by the bad steering geometry in official sets but which set has the most accurate steering? By that I mean "normal" steering, not articulated or 4-wheel. Best steering in a MOC (with instructions)? Quote
efferman Posted February 15, 2014 Posted February 15, 2014 i think the last official set with ackerman geometry was 8880 super car Quote
Kumbbl Posted February 15, 2014 Posted February 15, 2014 ?? What about e.g. 8448? iMHO it has also Ackerman ... Quote
D3K Posted February 15, 2014 Posted February 15, 2014 When you have two axles that turn symmetrically, where should the ackerman geometry "tip of the triangle" be? Right in the middle between the two axles, or at the centre of the opposite axle? Quote

Lipko Posted February 16, 2014 Posted February 16, 2014 Do you mean when both axles are steered? In that case my logic says the tip of the triangle should be in the centre in between the axles. Because that setup would mean that you could place a non-steered axle in the middle, and obviously the rule of thumb applies for that midle axle too. Quote
