Mini Rock Crawler Build SV 650 Part 6

Today I'm working on getting the suspension setup. For this project I'm using the Fox 2.0 Air shocks. These are air only shocks and can be made hard or soft just by adding more nitrogen pressure. The fox air shocks are super easy to adjust and really light weight, perfect for these smaller projects but they can also work well in jeeps and other light rock crawlers. King air shocks are also a great option if your build is like mine, but I feel like the Fox airs have a better factory valving setup. The Fox air shocks should go together really well with the mini rock bouncer as that's really what they were designed for.
Let me know what you guys think about the switch over to Fox Air Shocks instead of Coil overs Like I've been using?

You need a Hydraulic steering ram. That way the hoses move up and down with suspension. If you try a steering rack you will have to have telescoping steering shaft while rack is mounted to front end

@laymanengineer7502 2 жыл бұрын

I second that idea. We use them down here in southeast Louisiana on boats because of that versatility. Another benefit is the strength of the ram compared to a r-a-p steering, which I think would be good for a bouncer when you're bound in a rut or rock crevasse. Nothing will stop a ram and ypu can turn it with your finger on the steering wheel. Plus its way less complicated without any linkage

@logansteele7967 2 жыл бұрын

I agree with the boat hydraulic steering due to them having a check valve in them making it so only moving the wheel will allowing to turn as well as having it be able to flex without binding the steering linkage

Other people have offered this suggestion and its one I agree with: why don't you use bump stop rings/sleeves that attach to the shock absorber (at the bottom of the ram shaft)? That would eliminate all the headaches and mess of trying alternate external methods

@mdnovaman 2 жыл бұрын

100% this. Motocross bikes or mountain bikes don’t have external bump stops and there forks and shocks take huge impacts. This will only ever take slow speed impacts so a shock mounted bump stop around the shaft would work perfectly. Look neater and save a load of weight.

Putting the stops on the shock also buts the hard mechanical loads- straight ones and bending- through the shock assembly- the independent bump stops put the load at stop directly into the frame or strong suspension members. FR

1...Use a donut ring on the shock as a bump stop. Your way over complicating it. 2...Switch the shocks from front too back. You don't need that much stroke on the front. 3...You should run just enough nitrogen pressure to extend the shock about half way out or a little less. You want more droop than lift.

If you are going with uni joints make sure the yokes are parallel and your gearbox output shaft and your diff input shaft are parallel (Z formation). Since your tail end is pivoting you would go for middle the range of angle full travel causes for the diff angle and live with the consequences regarding varying velocity at the diff. Don't spend too much time on hard surfaces. Used CV joint driveshafts are plentiful and cheap if you want to remove the problem. I love your work and dedication. Thank you for sharing it.

Look at how all the air shocks buggy are set... 6-8 inch of up travel max. more pressure in them, more height you got, but also more spring rate... Air is really progressive, you wont feel it much mid travel but the last 5-6 inch are gonna be worst. You have to balance the ratio pressure/oil to achieve that, more oil, less air to achieve same height... but too much oil = hydro lock

@bobbynate4271 2 жыл бұрын

That thing is very cool sir😎👍. I would like to suggest a few things that it really needs. The first, bigger tires. One good reason is to roll over rocks/obstacles. Your really limited to obstacles just over half the tire diameter. Another great reason is traction. To get great traction you have to sacrifice tire hight. This sacrifice happens when you are forced to air down your tires to gain traction. At this point your will need to consider your gear ratios. Is the ratio high enough to produce enough torque. Then the bouncer aspect comes in to play horse power! The higher the ratio the less horse power you can effectively use for speed. Good luck I can't wait for the next episode. Thank you👍

Incredible stuff, and cool to take viewers on the journey. Never have I seen independent suspension components used to build solid axles. You know it would be cool to have the center diff in a square cage and 4-linked to the frame and where it only swung up and down, and then use the axles shafts as intended swung from sides of the square frame to the spindles…. A mono shock in the middle and coil overs on the swing arms ….
