Portal Axle
Original ideas from Zblj
Thursday 19 November 2009, by
This is a new component I design. Ideas from zblj. The portal axle is in 8 stud width (rotation point) so it’s pair. In opposition with my previous unimog axle, the direction is reliable and unbreakable. To compare with a normal axle, the portal axle have more ground clearance. Also, the Peformance in accidently land is better.

Hey,
When driving offroad, it is often the case when at least one of your wheels doesn’t grip enough because you are in such an angle with your axels (example: http://www.danfog.co.uk/school/Images/4x4road.jpg). With a differential, you would loose all power through this ground-untouching wheel. Or, you have to build a blockable differential and block it whenever this situation occurs.
To prevent that case and to stick with small designs, the only option is to forget about the diff. Then, of course, the design is not optimum and one of the steering wheels will spin too fast when steering, but with lego plastic parts and with a sandy (or earthy) ground, that shouldn’t pose any problem.
