This is how self propelled push mowers work. When you clamp down on the handle that causes it to drive forward, it tensions a pulley from the engine to the wheels, and causes the mower to drive forwards under the engines own power.
@@RU-vidcensoredmyusername I'm looking at a video of it now. It's a pulley/clutch system, the blade 'pulley wheel' is two plates, one is the input, and the other is the output. The other pulley wheel is actually an idler, and tensioning it engages the two halves of the clutch using a belt. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VukTdf6vMbI.html
You guys should try retrofit variable valve timing on a lada. I was thinking of using a bendix gear from a starter on the end of the camshaft. then you could pull the cam pulley in and out with the throttle to change the advance.
What you are suggesting is meaningless. For the motors existing in the experiment have an OHC camshaft drive. They are outdated. And modern Lada motors have a drive
Theres an awesome channel called Robot Cantina! This channel takes literal generator/mower engines, predator 212, 420 and recently 670cc engines and install them in a few cars, honda insite, some saturn, and this new car too with the 670 cc engine. This video here is a bit more rudimentary compared to Robots, either way, this is really cool 😄🙏
Those belts are only god for horsepower transmission of like 7-10hp, if the engines is driven easy would be fine for around a farmers field but not long lived. Need a big nasty cog belt for longevity
Old industrial machines used to be driven by line-shafting and flat (leather) belt - the first factory I worked in still had this, and the machines would have a fast and loose pully, the loose pully just spun freely on the shaft, if you moved the flat belt over to the fast pully (using a fork selector) it would drive the machine.
'Robot Cantina' videos 😉, they do projects like installing a 670cc V-Twin Predator lawnmower engine in a classic Renault R10 (670cc motor & CVT linked to the R10's 4 Speed gearbox), or installing a 250cc single lawnmower engine, with a supercharger & CVT, in a Honda Insight 😏 😎🇬🇧
Yeah, mower belts have fabric throughout the surfaces so you don't just melt rubber when slipping the belt. But it still worked, and they did say they would use regular car belts.
@@volvo09 its not the casing of the belt. its the belt itself. consider what torque is, and how its transmitted in a belt. theres teh pulley to belt friction, with a vee belt it wedges in there... and then it is solely down to cross section of the belt, the number of cords... tension. basically. an A section belt is good for 2hp, without slipping. they will slip before they snap. a lawnmower blade belt, generally a B section... takes about 5hp. "but my ride on mower has a 25hp engine, so nyer!" to spin a blade and merely snip the tips off grass takes sweet eff all power, so the belt is barely loaded. when you hit the heavy stuff, it starts loading down... think of what you can push a 5hp mower through by hand... and then when you actually clog it up? it simply slips. no damage done (i have a walker... damage equates to a few weeks and a LOT of money repairing gearboxes. dont get a walker with driveshafts) and the traction side of the ride on mower? its never really direct either. lots of power in the engine, but lot is wasted in just bearings, pulleys, losses here there and everywhere... and when buzzing around cleaning the turf its not really "producing" 25hp as its not loaded down. the governors keeping the throttle backed off despite you giving it full bunny... take the poxy lada to be 40hp.... one puny a section belt is extremely under-rated, it will , and does work... for about two laps of the driveway.
@@paradiselost9946 yeah I guess I described it wrong, as the (mower style) belt wears there is always that fabric stuff integrated throughout, so it is all the way through.
i need a comeback with the diesel pump injected lada, it was such a cool invention of yours, i need to see more, could you possibly tune it to make even more power? the diesel pump injected lada engine seems to be pretty powerful, so i need to see more if you can perfect the tuning on it or something, maybe find pros and cons of the diesel pomp injection? because it can't be so easy power, it definitely has some cons to it, also i would liked to see the roofless niva with the driving position in the back again, that machine is really funny, and also huge thanks for being around for so long and thanks for making crazty stuff always, the last video with the 12kg weights in each tire was a lot of fun haha
You should use a couple super heavy duty springs to hold tension on the belts at all times and flip the slave cylinder so it breaks contact with belts and pulleys when you press the pedal. Should feel like a squishy clutch maybe. And try snowmobile belts possibly.
Okay, how about another challenge? Take off the transmission and clutch, remove the drive shaft. Put a variable pump on the engine, and the hydraulic motor in the pinion. But wait, THERE’S MORE!!! Put two stacked pumps on the engine, remove the solid axle, and put a pair of hydraulic motors on the rear wheels. For a differential, run balancing hoses across the lines, left and right. Putting ball valves (for simplicity) into those balance lines will add something else. POSITIVE TRACTION! Closing the valves will force the wheels to turn at the same rate, where the open valves will allow the wheels to turn at different rates, because the balance lines will allow the fluid to go to the faster tire, or the one with less traction.
If you have your clutch cable attach to the other side from where it attaches now and add a few strong expansion springs to tension the belt when the clutch is released, the car will drive as with a normal clutch.
I had a similar setup on a small homemade diesel tractor, push clutch pedal to release tension. Also it had diferent size pulleys to give it low and lower range. A single moveable tensioner made sure I only tensioned one belt at a time.
I actually made a go kart that uses a belt drive directly from the engine with a very small flywheel on the engine shaft and a big one on the wheel axle with an idler pulley on bearing and a hand brake lever as the tension mechanism to help while driving you just tighten the belt as you drive and it just stays tight until you lower the lever
easy thing to fix having to push clutch reverse the spring to be above and move clutch cable below your welcome that should make it feel like regular car
this is an example of smart thinking guys well thought out and put together. not everyone can put something together like this and it work. good job very interesting. kudos to all of you.
DAF 33 variomatic drivetrain. A gem of a 1970's car with a vary speed 3 speed transmission drive using rubber belts. Also Ran as fast in reverse as forward.
@@mann_idonotreadrepliesthat’s funny while they’re used in the most rugged vehicles where breaking down can cost you your vehicle or life. Snowmobiles ,4x4 quads and utvs
Along those same lines, you can create a infinitely variable transmission with a rubber pickup wheel and a metal drive plate. Some self-propelled lawn mowers use this type of set up for varying the speed the mower travels. Probably will have trouble moving a car unless you get the friction just right.
just like cars with CVT gearbox. Two cones and large belt that gives you constant acceleration. Only thing stopping it from going full speed in reverse is likely a factory set rev limiter
After watching your steam powered car video (which I LOVED) ,I just wanted to suggest another alternative way to power the car that might be interesting. Try a Wood Gassifier, it's been used since the american industrial revolution and throughout the great depression. It essentially converts wood into flammable gas by carbonizing it instead of burning it. And an upside is by the time your done using the fuel wood you have perfectly carbonized pieces of wood you can use for smokeless cooking
great job, i have a question ,can i use a automatic gearbox instead of manual gearbox in a similar gokart which i am making almost compliant . will it work ? any suggestion from any body is welcome
I would mount the pulleys rigid, then, use spring loaded idler pullies, similar to those used in belt-driven snow blowers and roto-tillers. The belt between the engine flywheel and the transfer pulley can just be tensioned all the time, but the clutch pedal should release the tension on the belt between the transfer pulley and transmission input shaft. by using spring loaded idlers, it will automatically compensate for belt stretch and wear. they just simply press against the slack side of the belts, making them largely self-adjusting. The problem would be, that the engine could not hold the car back when you take your foot off the accelerator. The torque would be limited by the tension strength of the idlers, which would slip with the engine trying to slow the car. All go, no whoa.
a belt can only transmit a given force. for a single A section v-belt.... its about 2hp, at 3000rpm. any more? they start smoking, they burn out, and they fall apart. increasing tension does nothing but speed it up, and increase bearing wear... i did this with my backhoe, got all clever with an overcenter belt clutch as i was mounting a generator to it. the generator is fine, just squeezes in, on twin B sections for 10hp or 7.5kw. 5.5kva gennie. the hydraulics? after actually sitting down and doing some calculations, best case scenarios... i need FIVE a-section belts for this setup, and that will give me an estimated life of 2500 hours. as it is, i have an estimated life of 2.5 hours before the belt shreds. can use it for now but it is definitely getting revised soon!
How about taking just variator transmission from snow mobile or similar. You could drive without clutch!? Or using it just when it is stopped/standing for variator break. Although I'm pretty sure that will work as it is used also some tractors etc. Not sure how shifting gears would work, but I'm sure you guys would figure that part out too. 😂
I wouldn't say it's a 107% success but, maybe 101.5% The pedal has to work as expected. Make the springs pull the belts tight and use the pedal to unload it as with a normal clutch.
Isn't this how the Ford Model T worked. hold the clutch in to go ??? one of the few good things to come out of WW2 was the configuration of car control's now.
I f@cking love your channel. You guys come up with the craziest ideas. I couldn't help but laugh every time those belts chirped. Everyone who's ever used a riding lawnmower knows that sound. 😂
Whats with the paw sticker on the windshield? Please give the poor cat his car back 😂 On the belt clutch, how about put a big spring on it to keep the belt engaged and use the clutch to disengage it so it drives like a normal car? :)
Damn my father had that same exact model of the lada samara 1.5 liter fiat engine. Same color in the front i must say it was abit ugly but my father liked it.
"Turning a Lada into a lawn mower one part at a time." Hoping this means you eventually fit a mower engine to that Lada and see how many gears it can go through!
Covert the alternator into a motor thats powered with the battery, and then see if it has enough power to start the engine. Maybe even see if it has enough power to move the car?
This would have been SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOÓOOOOOOOOOOOOÓOOOOOOOOOOOOOOOOOOO Much better if you would have used spring tension to hold the clutch engaged and then the clutch pedal to disengage ......
