Closed driveshaft benefits?
Just as a thought I was wondering if anyone had any comments about why Henery went with the closed driveshaft over open?
What are the benefits/Shortfalls Just personal curiosity as I am getting ready to pull a transmission out of a 38 ford for the first time, ow yea does anyone have any pointers before I start. |

Ford was devoted to the single, transverse leaf spring suspension. Some might say because Henry was noted for being thrifty (one spring cheaper than two), others may differ. Whatever the reason, in order to control rotation of the rear axle on it's axis a rigid control device was needed. He favored the central mounting of the spring for the "better" wheel travel on the poor roads (moreso early century than later) of the day.

Also, with common 4-spring type setups the heavy part of all springs is on the axle...the extra unsprung weight is serious on a light car. The tube and the front radius rod allowed full control of axle without binding or torque effects from braking.

Re: Closed driveshaft benefits?
Another "advantage" of the closed drive shaft is only ONE universal. I'm pretty sure that the engine and transmission pretty much line up with the drive shaft and the universal only comes into play with deviations from the normal standard loaded height, such as more stuff in the back of the car or hitting a bump or whatever... Also, at the time, the pre-lubricated, sealed U joint didn't exist, and putting the universal "inside" made things somewhat easier.

exact science in some venues. Millwrights must be close to perfect making the alignments, even when using a flexible coupling, lest they have unnecessary vibration and put undo wear on bushings or bearings? comments? In other words, even a few thousandths nonalignment can be a catastrophe. Not to whip it to death, but it is also amazing how a small lead weight can erase the unbalance of a tire. |

Re: Closed driveshaft benefits?
If you rolled over a mattress it wouldn't tangle in the drive shaft, remember those pics of that?
