"Angry Horse" (4x4)

[wrmhaste 235]

I figured it was time to start a new topic for this build considering its come much farther than just asking questions about transmissions. this is my take on a 4x4. no where close to ready and i havent been taking too many pics along the way but here are some. It started as a 1973 16 auto. homeade front axle pivot mount, driveshafts, wheel bearing knuckles, and soon to be tie rod system

     I am a bit curious about your plan to coordinate the speeds of two hydros.    

This build has so much going on that it deserves way more   of the front drive system.     

[wrmhaste 235]

They will be linked together by heavy cable. Just like choke and throttle cable. And of course adjustable. I have many more pics but they are currently trapped on a phone that doesnt like to cooperate. I know i have pics of building the pivot point and also seeing just how far it will pivot.

Awesome job and project  !

 

Check these guys out for push,pull cables http://www.midwestcontrol.com and other parts I'm sure you could use on this cool project  !

We need more pictures . What motor are you going to use.

I have a friend that owns a small engine repair shop so I just order anything I'm looking for through them. That is a good site though.  Have you ever heard of the surplus center?

I'm not sure why the reply didn't post last night but I will have more pics soon and I'm hunting for a m16 single cylinder but I'll probly throw a 12 on as a temporary

[wrmhaste 235]

Ok guys got some more progress.  It now steers. Quite well to my surprise.  

[meadowfield 2,570]

Awesome, great to see another 4x4 project

[wrmhaste 235]

Thanks I'm trying.  It's very slow going. I don't have a lot of time to work on it. It's been a very fun build so far though.  As soon as it is operational I'm going to start building the plow for it.  I'm thinking of a 60" hydraulic v plow with down pressure.

Not knocking it by any means ...NICE WORK !

But , I hope you have plenty of those Oil-lite bushings ( for the king-pins ) on hand .

[wrmhaste 235]

Thanks and I'm all for criticism. Helps get better ideas floating around.  I know there will be weak links here and there. I do agree that those probly will be the first. There isn't any bushings though.  Those are thick wall machinist sleeves with 3/4" solid round going through them.  They will be getting grease fittings.

    You are tackling a project that most of us wouldn't even consider attempting.  

Not being an engineer I can't say this is necessary, but it seems to me that some triangulation of the steering pivot points will be needed. There will be a lot of torque applied when turning and it could be an area that could fail.

[wrmhaste 235]

Thanks,  it's the challenge that keeps me motivated, well that and having a really cool machine at the end.  And good call on the steering pivots being weak.  I never thought of that. That's going to give my brain something to work on while I'm at work this week.  Next big challenge is shift linkage and belt routing.  

[Sarge 3,463]

I'd add a triangular plate to the top of the axle housing , the area where you currently have the king pins - use that plate to add a couple of welded arms to support front/rear loading against the king pins .

 

How do you plan to tackle the belt drive itself ?

 

Sarge

[wrmhaste 235]

That's kinda what I was thinking for extra support.  The drive belt is going to be a bit tricky.  I plan to use one belt with at minimum 2 spring loaded tensioners. Also I will have a few idlers to keep the belt on the front pump while still allowing it to pivot. It's basically going to be trial and error after I set a motor on it. Hopefully more trial than error

This is what I am most concerned about, the two hydros being in synchronization with each other has me thinking, but haven't got a good answer.

[wrmhaste 235]

Getting it perfect might be tough.  I'm thinking if I get them very close then have one be slightly variable by involving a spring, similar to a governor/throttle setup, it should move free enough to find the path of least resistance and compensate.  That's the initial plan at the moment anyways

       While in high school I worked part time at a service station; low budget operation but we did a little of everything. The service truck was an old Dodge Power Wagon which had miss matched tires on it, they weren't off by much, (7.50 X 16 front and 8.00 X 16 rear if i recall correctly) perhaps an inch taller in the rear. It pulled great in mud or snow but was a bucking bronco if all four tires got traction at the same time. Had to take it out of 4 wheel drive to keep it from self-destructing.

Those power wagons were awesome!  It may have felt like it was going to explode but I would bet a drive shaft or u joint would go before that transfer case.  Most of them were cast iron and weighed a ton

This is basically what i designed on paper myself!  great minds think alike! however mine involved a manual transmission front and rear, and mounting the front axle like project c4 on the axle tube/ bolting it to the new steering knuckle support that slides over the axle tube.  I am interested in how you were able to cuff the axle housing because it is tapered... did you just slide a square tube all the way up until it stopped? how do you keep it from wobbling? also could we get some close up on the front steering knuckles and universals? Nice Build! I hope to join the 4x4 club in a few years!

Perhaps a viscous coupling or 2 to combat the axles winding up and making it a bucking Bronco.

I actually took two pieces of c channel and welded them together to match the taper. There was a lot of grinding and there will be much more.  I'm still not happy with how boxy the hubs look. That can wait till after testing though.  I'll get some better pics soon.
