Rig movement hitting kerbs

Hi,

I'm wondering, How much is too much for the rig is moving? For example, If i hit the kerb, does the rig moving a bit or it's the Butt Kicker's job?

Thanks, I think my rig speed and precision is right on the way but the speed from steady still to accelerate not the return speed. How do I adjust return speed? My motor's return speed is way too fast, probably too much. Using 24V wiper motors.

I have checked my rig, 1 motor has play on the lever or shaft. There is setscrew that I can play with to eliminate the play but it still has it. How do I adjust more if the setscrew touch to tip of the worm gear?

This setscrew...

There are worm drive motors (specifically related to sim builds) that have zero lash. So if you choose the right worm drive motor you won’t have the end play issue. I would consider a full metal worm and gear for this application with a slight trade off in the gear box being slightly noisier than plastic gears.

Hi Kevinski,
I have 2 sets wiper motor kits, one set is smaller motor but both have plastic gears. Does that mean I have to find wiper motors from old car maybe?
Both sets I have are truck wiper motor.

How about using wheelchair motor? Type is MY1012 250W 24V.

@deeph46 I can’t comment on the wheel chair motors as I haven’t used them. Here is a link to my YouTube channel with me driving my rig in assetto Corsa. I’m a really big guy. I way about 116kg and these motors are awesome. It helps to have a balanced motion platform to begin with. Very important. The motors I use can be purchased here in Australia. They are very powerful and are a full metal gear box with zero lash. Check out my YouTube channel for all the info and how to build my rig. I’m sure these motors would suit most applications. You can find the link to these motors on my rig in the YouTube description. Hope this helps.

@Kevinski, That motor looks like wiper motor, does it? I'm using similar that type of motor, instead mine are 24V motor. Are there any advantages using lower voltgae (12V) one? Smoother?

@deeph46 yes the motors I am using are heavy duty industrial wiper motors from big mining dump trucks. 24volt stores more power and can reduce the need for heavier wiring, but it’s not the voltage in your case I’d be focusing on. It sounds like you need to find a good motor with heavy duty worm and gear drives. Something like I’m using with all metal worm and gears. Do you have any pics of your motion platform? How did you build it?

@Kevinski, I will take picture for my rig after I tidy up my wiring, still like a rat nest right now lol

Here is the picture...wiring still like a noodles though lol

@deeph46 Nice mate. Looks nice and compact. Some nice peripherals you have going on there as well. I'm waiting on a Fanatec csl DD 8Nm wheel base, Club sport wheel rim with a universal hub, some Club sport V3 pedals and a club sport 1.5 shifter. Decided it was a bit silly having a kick ass motion rig with a G27 wheel and pedals. How's it all working for you? Are the motors moving you around ok? It looks like a pretty small uni joint you are using there. Bit hard to see in the pic.

Yes, want to make it as small as I can. I actually can make more smaller footprint by cutting the pipe behind the seat. And it cost me around $200 (just the motion parts) for my motion rig. Using 3/4" pipe and 3060 aluminum profile. I want to add 3rd axis for heave in the future, for a while I really love how 2DOF performed.
You also get great peripherals though. I was using G27, Thrustmaster T300 and Moza R9 for the DD. R9 doing great for me, lots of torque with 9Nm. It can break my fingers lol..

Motors are also doing great right now, noticed some plays but minimal. Still using my previous motors with plastic (Nylon?) gear.

Yep, the uni joint is pretty small but it handle pretty well. It was joint from steering post I believe.

@deeph46 Sounds good. If it's working and doing as it should, then that's all that matters. I looked long and hard at the Moza R9. They look really nice. At the end of the day, because the Fanatec CSL 5Nm wheel base can now be upgraded cheap thanks to after market boost power supplies, it's a bit cheaper than the Moza R9 for similar performance. I do really like the looks of the Moza gear and their software is really cool as well. I was also looking pretty hard at the Cammus 16nM wheel bases and pedals. Problem is their software is a bit behind. I think 8Nm or 9Nm wheels are plenty of power for long driving sessions. I think my arms would go numb using any more than that!
