LifeTrac IV/Research Development/Wheel drive
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
