Hey Guys,
I am very keen to discuss our new beam axle design. I will be posting pics on photo bucket with the user name oz_olly. I will make another post a little later with links to the other significant beam axle threads however, there isn't really a thread for consolidated discussion.
For 2009 ADFA presented a car with front and rear dependant suspension. The front was a peg and slot beam axle (inspired by Model T Ford) and the rear was a de Dion Twist Axle. So far the performance hasn't really been investigated as we clocked up more km's at the comp than in testing.
I am keen to develop the design looking for simplification opportunities, weight reduction and stiffness increase. I will be designing an experiment over the christmas break to do some installed compliance testing.
The beams themselves are fabrictated from 4130 tube and sheet. Thr front unsprung, disconnected completely from the car weighs 25kg and the rear 24kg. We are also using the Hoosier 18x7-10 R25B which is about 4kg. I would like to look at the 6.0x18.0-10 in the LC0 compound.
Cheers
