This is my near 1:1 scale model of the second generation hybrid transaxle from Toyota, which is also used by Lexus and Suzuki, and similar to the system used by Ford. I explain all of the components in this video, where I also show how it reflects the power flows when driving a hybrid car with this system. For this video I use the Lexus CT200h because... that's the one I have. This is the full model: In one end we have the 1.8 liter inline 4 piston engine: The model is rather simple. There are no counterweights on the crankshaft, no oil pan, no valvetrain... etc. It pretty much just consists of the crankshaft, cylinders, conrods and pistons. The pistons are, however, almost of the right bore: and the stroke is also almost right. I am using the small 1x1 round tiles because the curved slopes have sharp edges that make the pistons jam within the cylinders: The flywheel is super simple and bolts right onto the crankshaft: In a real car there is what appears to be a clutch. It is, however, not a clutch. It is a damper with some springs that allow for a small amount of travel between the two sides. This is my not-very-accurate LEGO version of it: The magic happens in the power split device which is flanked by the two motor/generators: The LEGO model is powered by Power Functions motors: In the center there are two planetary gears which are joined from the ring gears: In the video I show how these components work together. My hope is that this can help demystify the internals of the most popular hybrid system in the World. Many people think the hybrid system is rather complex, and Toyota doesn't help with its misleading "eCVT" naming. In reality this system has fewer moving parts than a DCT, slush-box automatic transmission or even manual, since there is no clutch, no traditional torque converter and no "real transmission".
Vilhelm22 posted a topic in Special LEGO ThemesI was just on the 'Everything we know so far' page for 2021, which I check regularly, and realised that despite I having known about both these sets for at least a month, I've seen almost no discussion of them Eurobricks. If there has been, can a mod please merge or delete this post. Just for the details: 10280 Flower Bouquet 756 pieces US$49.99 / EUR49.99 / £44.99 10281 Bonsai 878 pieces US$49.99 / EUR49.99 / £44.99 These are the first two unbranded small 18+ sets. The PPP seems pretty good. 10281 is listed on Brickset now, but with no info. 10280 is not. Interestingly, 10281 has been put under 'Sculptures' - the fourth in this category, after Statue of Liberty, LEGO Minifigure, and LEGO Dragon (all released 20 years previously). Both sets are scheduled for release January 2021. A leaked image of the Bonsai was posted on Instagram today, probably resulting in Brickset adding it to their inventory. What do you think of these sets? Is the small size a good thing? Do you see many more being released in the future? If so, what? Discuss below.
Hello, this is SIG P226, a semi automatec pistol. I built in some funktions, so please watch the video . It´s part of the pistol set, featuring pistols of different time periods. (Take a look at the Colt Dragoon and the Flintlock Pistol )
