Advisor: Mehrdaad Ghorashi University of Southern Maine Engineering EVOLUTION AND INNERWORKINGS OF A CAR DIFFERENTIAL Abstract • Create interactive demonstration pieces that display basic concepts of a car differential using visual aids as in the educational video ‘Around the Corner (1937): How differential Steering Works’.  • Fabricate a custom stand for an open ended car differential. The final design of the car differential will be run by an on/off switch and a motor.              Figure 1. Snap shots from ‘Around the Corner (1937) How Differential Steering Works’. Introduction and Background A car differential is used to transmit power from the drive shaft to two separate outputs; wheels. A complex gear system allows the active wheels of a car to turn at different velocities. This is the solution to cars not being able to turn if they were to have a solid axel. Our project demonstrate how the differential allows a vehicle to turn without binding its wheels. Hardware/Software Operations •Hardware: •Welding •Plasma cutting •Right angle grinder •Lathe technology •3D printing technology •CNC machine •Abrasive chop saw •Milling •Heat forming •Software: •SolidWorks 3D Design •SolidWorks Drawings •SolidWorks Motion Analysis Conclusion There are two final products: 1). A mini differential set that, in a classroom setting, demonstrates how the spider gears can transform one rotational input to two separate variable rotational outputs. 2). Custom-fabricated differential that displays the innerworkings of a vehicle differential in motion using viewing ports. Process and objectives •Simulate a working differential with brakes and an input power from an electric motor. •Create different generational steps of gear systems using SolidWorks to demonstrate the purpose and evolution of a car differential.
