Steampunk Semi by gunslinger87 Steampunk Semi by gunslinger87
Well folks! He is my submission to the Guild Of Steam group's Second monthy design contest. This contest's theme is taking a moder vehicle, let's use a car or truck for exampe, and concieve it as if it were built durring the 1870s or 1880's.

Here I took a modern day Semi Truck (som of you may know it as a "Tractor Trailer" or an "18 Wheeler") and designed it as if it were from the late 1870's or early 1880s. YES, Atticus DID do the same thing. He also made a steam powered semi truck/locomotive. But I DID NOT copy him! As one can plainly see that there are some MAJOR design differences. Atticus' design does have an advantage, speed. By using the some powering methods as a traditional steam locomotive he has the advantage of speed. My "Semi" on the other hand is slower, I'd guess its max speed to be at or just under 20 mph. But would average around 15 mph and just under. Which for the period was a decent rate of travel.

But I'm NOT here to debate about each of our design's flaws. I'm here to submit MY design. I took insparation from the famed Climax geared steam locomotive and also from the Ex-D&RGW Rotary Snow Plow "OY". Unlike a Climax loco, it does not have a "Gear Box". The transmission of power from the pistons to the rear axels comes from a beveled gear set similar to that on the D&RGW Rotarys. The frame is rigid and the axels are not sprung. At the time of my conception of this contraption I couldn't figure out how to have suspension on the axels and not mess up the drive train. To compensate for this I designed a "Floating Cab", The cab is suspended using similar srings like those on the seats of old wagons. The wagon frame and body were all rigid but the seat was on springs to make the ride "Smoother". Albeit the springs used on my "Land Locomotive" are far more heavy duty.

As for steering, there is no wheel to turn. Instean the ends of the front axel have universal joints and a special mechanism to keep the front wheels alinged correctly. the system is similar to how modern vehicles steer, but instead of a steering wheel there is a actuating steam cylender/piston the is used to "Point" the wheels in the desired direction. Can't really see it and hence why I have explained it.

At first I was going to "Market" the design as a machine built by "Climax" due to the very similar set up used on their locomotives. But I felt that the Deviation title sounded better. ;p

I hope you all like!

PS: Also experimenting with a new signiture. :D

Heard of a Sentinel steam truck? They should race/tug of war.

It sounds familiar, though this design is more for hauling, not speed. (though I'm considering changing the rear drive wheels into tracks) :shrug:

Tug of war then?
gunslinger87 Featured By Owner May 22, 2014
A tug-of-war contest? It would win, hands down. :iconfoxhahaplz:

I'm meaning this Sentinel.…

It would probably still win. But then again, maybe not. The only way to know for sure is to actually do it. ;p

Well, that Sentinel runs, you've got the specs on yours, why not?

I've actually been thinking about completely redesigning this concept. I went to trucking school for three weeks and learned a lot about Tractor Trailers. (I still haven't gotten a clear answer as to whether they're "Trucks" or "Tractors") :shrug:

But there's a lot I left off of this that I didn't know that Big Rigs had, such as an air compressor and air brakes/lines. (Actually I did, I just didn't think about it at the time of drawing this.) ^^;
