LifeTrac IV/Research Development/Wheel drive

=Overview= This page is to get a better understanding of the engineering and design requirements for the wheel drive assembly.

Quick Connect Wheels - Quick connect wheels updates are generally posted here.

=Shaft Load Bearing Capacity= Currently a 1-7/8" shaft is used on the LifeTrac III. Analysis is required to determine if it is strong enough while using standard carbon steel

=Shaft Torsion Limit= Analysis required for using a single g8 bolt and 2 bolts, with 1-7/8 shaft

Analysis required for shear limit using 3" shaft with 2 g8 bolts, 1". This is for scaling analysis of bulldozer. Goal: 16,000 lb of pushing force for prototype 1 using same design with jackshaft

=Quick Attach Wheel Mounts= The quick attach wheel mounts challenge at GrabCAD has come to a close. Analysis required on the chosen winner and other entries to try and gain as much insight to the design as possible.


 * GrabCAD Challenge Results
 * GrabCAD Challenge Winner - Winner chosen by Marcin for quick attach mechanism
 * Another GrabCAD Entry - Interesting points brought up in this entry with regard to the load concerns.
 * For the record, this design should have won. Ultimately this is what the Universal Rotor is going to end up looking like. It's simply a better compromise between all the different requirements. - Matt_Maier 2FEB2012
