VKTechnic Posted October 13, 2014 Posted October 13, 2014 (edited) After watching a 4.5 hour documentary on rally racing, I think it's time I build my own rally car. The front suspension is already complete: a front McPherson strut system measuring only 15 studs wide (not counting the wheels). Next up: rear trailing arm suspension!

MrNumbskull13 Posted October 14, 2014 Posted October 14, 2014 This will be interesting... Make sure it's fast. Quote
Doc_Brown Posted October 14, 2014 Posted October 14, 2014 Thats looking really sweet! How well does that setup return to center? Quote
VKTechnic Posted October 14, 2014 Author Posted October 14, 2014 Thats looking really sweet! How well does that setup return to center? Really well. I use this setup in most of my models. Quote
Doc_Brown Posted October 14, 2014 Posted October 14, 2014 Really well. I use this setup in most of my models. Ahh cool! How well does the M motor stand up over time? Quote
VKTechnic Posted October 14, 2014 Author Posted October 14, 2014 Ahh cool! How well does the M motor stand up over time? Same as any old M Motor Quote
XAxles Posted October 14, 2014 Posted October 14, 2014 Can I bring this to WRC and win like Citroen or VW? Quote
Rishab N Posted October 14, 2014 Posted October 14, 2014 Looks good. I hope you use buggy motors Quote
PhyBuilder Posted October 14, 2014 Posted October 14, 2014 That's this one, they have been used in some NHL hockey sets. They're expensive without comparison, but I managed to get five of them in 4 colours, for only € 2,95 on a German Ebay Listing (...). They're useful, I use them to keep the steer of a motorcycle-MOC straight. Quote
Mikuri Posted October 14, 2014 Posted October 14, 2014 Bleh, this orange part is keeping me away from copying you ;o; Quote
Thirdwigg Posted October 14, 2014 Posted October 14, 2014 How are you going to set up the rear suspension? Quote
Zerobricks Posted October 14, 2014 Posted October 14, 2014 I suggest you to use servo motor, because M motor will stall and eat up lots of power from the drive motors. Quote
GallardoLU Posted October 14, 2014 Posted October 14, 2014 Im really curious what era Rally car your headed towards, given what we can see I'm guessing late 70s early 80s, just before the onset of 4WD, and AWD cars. (I only guess that based on the lack of power able to go to the front wheels) Quote
VKTechnic Posted October 14, 2014 Author Posted October 14, 2014 How are you going to set up the rear suspension? Hope this answers your question: Got the rear swing arm suspension in place. It's only 13 studs wide (15 with the wheel mounts) and it has a limited slip differential. The final gearing is 1:1.5. I suggest you to use servo motor, because M motor will stall and eat up lots of power from the drive motors. Only one problem with that: I don't own a servo motor (and don't have money to buy one). Im really curious what era Rally car your headed towards, given what we can see I'm guessing late 70s early 80s, just before the onset of 4WD, and AWD cars. (I only guess that based on the lack of power able to go to the front wheels) I'm going for an old Datsun 1600 SSS rally car, based on this: Quote
VKTechnic Posted October 14, 2014 Author Posted October 14, 2014 Looks good. I hope you use buggy motors I'm not sure I can fit them in, but I'll look into it. Quote
__________________________ Posted October 14, 2014 Posted October 14, 2014 Really well. I use this setup in most of my models. Didn't some genius make a list of most accurate return-to-center modules (all approx. the size of the hockey spring) and determine the hockey spring the least accurate? Quote
Nazgarot Posted October 14, 2014 Posted October 14, 2014 Cant wait to see how this shapes up. Nice work so far. I would love to see your front hubs. Any chance of an image without the wheels? (The rear suspension from below would also be great!) -ED- Quote
Technyk32231 Posted October 14, 2014 Posted October 14, 2014 I also have a good Macpherson strut setup, good for rally cars. I might post later. This looks really promising so far! Quote
timslegos Posted October 14, 2014 Posted October 14, 2014 I would love to see how you accomplished the LSD. tim Quote
Lakop Posted October 14, 2014 Posted October 14, 2014 Interesting. I like the two M motor set up for drive I must try that myself. Look forward to the completed model. H Quote
VKTechnic Posted October 15, 2014 Author Posted October 15, 2014 For those of you asking for more detailed pictures: Rally WIP 3 by VKTechnic, on Flickr Didn't some genius make a list of most accurate return-to-center modules (all approx. the size of the hockey spring) and determine the hockey spring the least accurate? Sheepo had a writeup a while back on some alternative return-to-center mechanisms. The reason I use the hockey spring is it's compactness - it's the smallest solution by volume. I would love to see how you accomplished the LSD. tim I connected the differential housing to a clutch gear tied to one of the outputs, like Efferman did here: x-ray by efferman, on Flickr Quote
piterx Posted October 15, 2014 Posted October 15, 2014 the rear axle is really clever :) great chassis! Quote
Zerobricks Posted October 15, 2014 Posted October 15, 2014 Brilliant suspension setup, especially the use of the connectors in the rear. Quote
MajklSpajkl Posted October 15, 2014 Posted October 15, 2014 Are the rear wheels rolling ok? The CV joint axle piece is held only by one stud hole... Funny, when I build, I discard such great ideas (if I got'em ofcourse :-)), because of prejudice, that this sure cannot work... Quote
