Do you think a jointed axle only on one side of the rear end would be considered independent suspension?

 

I think it probably would especially if it gave an advantage but I'm asking anyway as a Christmas gift to all.

Ok, so how are you driving the other sidè ? I say one side better get rid of the crutches. Yes

[dirtstudent2]

I'm thinking the U-joint driven axle would be on the left rear with solid axle on the right.

 

I'm thinking the right side rear tire then could be cambered and turned(real rear wheel steer), while the left could be used for conventionally thought of rear wheel steer which alters the  centerline of the car.  You'd could get real right rear wheel steering as in a zero turn mower with cambering of the right rear tire similar to the right front and control how you set the center line of the car at the same time.  Being it would only be used oval racing only the left side would need to be jointed.

 

Just some fun thoughts(for me anyway) on possibilities. 

 

If not legal might it be cheated by having the solid rear axle somewhat flexible on the left side?

I suspect though flexing the axle racing the downfall would be heat buildup because of the flexing and twisting an axle.

 

Now that's got to get someone thinking on it. 

 

 

edit:  before someone else says it.  where'd I leave that joint

Ds2. You remember when the micro sprints first hit western pa. ? There was a guy building them up around Hickory speedway. Solid axle but the right side was set up on a swing arm, weirdest dam thing I ever saw. From what I was told they couldn't keep the chain on, to much flex and they would go flying off all the time. So, I think your left side axle would be destroying u joints.

Lite Craft in Leeper built micro's like that. George Bischoff was the owner. I had 2 of them. They were bad fast UNTIL the left side drive cars were designed. AH the good ole days.

I did a google search and is this who your speaking of?

If it is the resume is very impressive.

If your familiar with karts too, might what he did on the micro relate to Phantom Triton Jr with the brake on the right side to cause right side flex, mainly so young drivers can better keep their foot in it some or a lot while turning?

[dirtstudent2]

Then once you move on to the left side drive cars and them being to better use simply because of weight location, what stagger is available, it changes the whole ballgame mid corner off.

 

I hope I just wrote down what you observed as the difference.  ?

I admit the last two posts are out in left field.

 

The reason for them is I'm very interested in what others think made for the improvement when micro's went from mainly having the engine on the right side to putting it on the left side.

Yes the obvious answer was to get more left side weight, I hope?

 

But what I'm really interested in is the on track improvement which made them better to the point the engine is still on the left side.

I think the main on track improvement was mid corner off.

Meaning with the engine on the left the car could be held down towards the bottom of the track better, mid corner off.

 

thanks

 

edit:  No matter what the only answers with real credibility will come from someone who drove both or was in the drivers seat and saw what others could now do better on the track, that they could not do.

DS2, yes that is the guy who built my micro's. From the seat of my pants, the right side drive car was better in and on the curb. The left side drive cars were wicked from the center off and all around better on the bottom. I liked mine a tick free in. That way i didn't have to "turn" the car. It was already pointed to come off straight. Keep in mind, i was in an era of oil shocks and basic valving curves. Lots of memories though. I have pics of the 2 Lite Crafts.

Thank you.  I sent you a message.
