My version of a stick, This could go somewhere

[joshm101]

Hey everyone. This is just a prototype idea I've been thinking about for the past few days.

What is it ?

I call it the "JM CREATIONS SS (Super Stick)

Essential what it is is a long piece of metal tubing. This piece of metal tubing is cut in half.
_____
One half has a pin glued or welded in the center of it about 1inchlon _____===

The other Half Has a hole drilled in it right through the center about an inch long.

Welded to the side with the hole drilled in it is a vertical plate. This plate is welded upright on the tubing. This plate has a perfect half circle machined out of it

On the half with the inch long rod coming out of it is another rod welded to the top of it to corrispond with the plate. Its shaped like this

____
l

This piece of metal Has a threaded hole drilled into the longer rod. The first half goes through the second half And the bolt goes through the longer rod. This allows the chassis to articulate 180 degrees (If you make the plate around the whole piece of tubing with a circle drilled into it). Next just mount the axles, Links and suspension and you will have a killer chassis.

Tell me what you think, dont flame me, im just a noob.

[insanerc]

No flames here but I just don't get it. Is the purpose here only to eliminate rod ends and also I have a hard time picturing how the suspension will function. I also need to add that 180 degrees of articulation would be upside down to the other axle and 90 degrees of articulation is generally considered too much.

Ive checked everything out. It will work. Its just a little complicated. The whole point is to have a stick with suspension

Doesn't the Stick already have suspension?:?

[freetimecrawler]

It has,as I'm sure you know, articulation, no up and down suspension. But what do you need that for for crawling? Not like your going to be riding in the thing and want a smooth ride.

[insanerc]

To elaborate on what freetimecrawler has said the stick does have suspension but doesn't have a floating or full live axle so to speak with its rod end attachment to the backbone. Seems to me what you are saying is that your design does give the stick this fully live axle and maybe I'm just having a hard time seeing it without shock mounts, shocks, and with the axle attachment you show in the front of your drawing which would not be possible for a fully live axle.

Looking further ahead I'm not sure if I see any advantage this would give the current stick in rock crawling but do definitely see the advantage it would give it in bashing and for all around use. If you take a stick as it is and drop it from about 4 feet you will notice that the only cushion it has is the tires and it will hit very hard and possibly break. If you add a fully live axle them you will add true suspension movement to it during such a drop which could be used to simulate a jump landing. Anyway as said maybe I just don't see it here but I'm always one who supports thinking out of the box. You may want to look at building a mock-up and see just how good it actually functions and whether there are any true gains to be had for rock crawling.

sus-pen-sion

n.

The system of springs and other devices that insulates the chassis of a vehicle from shocks transmitted through the wheels.

I thick the shocks on the Stick qualify as suspension. While it may not be suspended in a traditional means, the shocks on the Stick allow the chassis to be "insulated" from shock to a certain extent.

[RD400]

You can not insulate shock if the parts are bolted together. Remember kiddies, the clod gear boxs (axles) are bolted to the chassis via a ball joint at the top of the axle and links at the bottom.

As far as your chassis design, can't make heads or tails of it

Sure you can. The motor is my truck is bolted to the frame, but is insulated by the rubber mounts. True the axles bolt to the chassis, but they pivot on that point and are dampened by the shock in their arc of motion. Like I said, not a traditional form of suspension, but suspension none the less! And I too don't really get that design?:?

[dezfan]

Because the Sticks you are describing use the chassis as a torsion bar. Which is a spring. A traditional Stick w/ shocks use a coil for the spring and allows for dampening as the shock piston moves through the shock oil. Both work fine. The traditional one is just more tunable.

[RD400]

After running both styles of stick, I like the shockless kind better. I don't see the point in slowing the reaction of a crawler that never gets over 3 MPH

Almost forgot, the shocks on a stick are not preventing shock from being transmitted to the chassis from the tires. They are just slowing the speed at which the chassis rotates. If you were to put some 19 turn motors in a stick clod and run it across a gravel parking lot, the thing bounces like a skateboard. All of the shock from hitting those little peices of rock is transmitted directly to the backbone/chassis.

[insanerc]

In what state is a yo-yo hanging at the end of a string? Answer: suspended. Let's define the word suspend from which suspension originates. By Merriam-Webster not me.

a : to hang so as to be free on all sides except at the point of support


Hmmmm, sounds like Dez is correct to me Suspend does not mean free of attachment.

Two differant words with SLIGHTLY differant meanings. If you have ever owned or built a stick you would know that they have no suspension. My pan cars have more

Also, the axles are attached at 3 point, not just one like in the definition of suspend.

[dezfan]

Looks like we have another "ricer" vs. "old iron" debate! I have never crawled a Torsion Stick, so I really don't know how they react.:? We we will have to agree to disagree. I still think the traditional stick is supended!:-P

[RD400]

Sound like a plan DEZ, got any pics of the grunt on rocks yet?

[dezfan]

Only if I put pontoons on it! Friggen rain! Never rained like this in Cali!

[insanerc]

Actually I have owned both types of sticks and have pics of both of them here on this forum. I can't say whether I like the shockless better than the shock version because it's too close to call. Maybe that says the shockless is better due to its simplicity, I don't know. As far as the suspension debate I could argue my point further and was prepared to, lol. What a waste of time huh? Agreed, we disagree.

[RD400]

Wow, reasonable people? Am I on RCcrawler?

:-P

You suck, and I am always right!:-P














Ahhhh, that is much better!

[Cole82]

I agree with dezfan the stick does have suspension. If the axle moves at all, it is suspension.
The two sticks are so close in performance it's more driver skill than truck. I prefer the simpler shockless design though.

Wait:
