The worst part about the cybertruck sycophants is how they all post in that annoying-rear end voice like chuds with the terrible "folks," or "and so it begins" selfsuck posts like they're super magnanimous to tell you, the idiot clown with no access, about how THEY got to see some piece of poo poo cybertruck at a basically public cybertruck event they begged to get into.

I dunno man, apparently a lot of people are asking for public transport and you load up this waste of money? A research department at my work place is deep into wireless charging of cars and even they haven't bothered with this. https://twitter.com/CityofDetroit/status/1730045237353964030?t=YYLWU5MSo7caxmkBZCdqcA&s=19

Rigged Death Trap posted:How much would that charge anyways They claim up to 100 KW (from the Swedish test in 2019). They also made a loop of it earlier this year and ran a modified Rav 4 on it driving for a total of 100 hours non-stop to demo the tech. 1942 kilometres in 100 hours so 19.42kph they were able to manage without draining the battery. While it's impressive, I'm not sure a little stretch of road is gonna do poo poo unless cars are sat on it for good while. The F-Zero method of having this built into parking bays could potentially work well though.

Olympic Mathlete posted:They claim up to 100 KW (from the Swedish test in 2019). The biggest problem with F-Zero style Qi parking lots would be coal haulers acting stupid, taking up all the EV spots. But if there was a way for the coils to mess with their vehicles (like drain their batterie, something not permanent) maybe that would stop people from deliberately being douchebags. Alternatively, is battery swapping really impossible? I think Tesla demoed a big battery swap machine years ago but it had problems. But hypothetically, what if cars had a fuel tank sized swappable battery in addition to a larger floor battery? The larger non swappable battery would offer like 200 miles of range, and the swappable would offer maybe 30-50 miles of range, just enough range to make it to your important meeting on time. I know Elon gave up on swappable batteries but lately I think Elon "tech Jesus" Musk is an idiot so I don't think his failure to make it work really means the tech is not possible.

The swappable battery tech works extremely well, where it's needed. And it's most needed in a short range delivery business, where delivery drivers can swap small batteries when back at homebase, in order to continue running orders. While it's a logical idea, most businesses using this model just buy extra scooters and keep those on the charger instead of swapping batteries. Nobody needs this poo poo in their car.

While it's a logical idea, most businesses using this model just buy extra scooters and keep those on the charger instead of swapping batteries. Swappable battery tech is fine for like you say, short range, lightweight setups. Taiwan has a fairly solid market for electric mopeds and there are battery swap places in plenty of spots. You pull up, swipe your membership card, place your batteries in the machine and it lets you know which fully charged batteries to pull out and use so you can be on your way again. It takes less time than to put petrol in! The one battery network Gogoro has some 1.1 million batteries in circulation in 12,000 battery swapping stations 99.5% of which are on Taiwan itself. I definitely feel battery tech is being wasted in huge, heavy cars that might never get used for any real mileage but then I believe that most people could live happily with some form of 2 wheeled transport if they so desired to travel with a vehicle of their own... Your mileage might vary

CommieGIR posted:I feel like I've seen that control arm setup on light duty trucks. Use of a multi-link suspension is good, what looks like a bad idea is how flimsy the upper control arms appears. The aforementioned MX-5 upper control arm is pictured below. Note how it's shaped, particularly how its stamped around where the upper ball joint mounts, and compare that to the flat unstamped portion of the Tesla control arm.  Considering that this control arm is what is keeping the wheel centered in the wheel well, it's important to get right. Stealing the below from a universities formula team design report, they came up with 5 likely failure modes for their upper control arm design, which can help visualize how the tesla design may fail.

It's been 15 years since my college courses on suspension design and FEA stuff but uhhh..... that looks less than ideal for a vehicle as chunky as the cybertruck. Plus where it attaches to the structure, most vehicles that size seem like they bolt the upper arm bushing into a bracket that's formed or welded to the structure, not attached with a pair of what look like cap screws?

Boaz MacPhereson posted:I saw those too, but I'm looking on my phone and can't tell if they're cap screws or rivets. Nah the dogbones are bolted into a structural bit of frame, you can see the bolt heads in this photo.  I'd prefer to have the uca beefed up or at least have a lip all around where the ball joint sits but it does extend far enough out that I wouldn't be terribly concerned about it deflecting side to side. It would be less resistant to deflecting front to rear, but to do that by an abnormal amount you'd need to have massive movement of the lower ball joint that you'd only see if there was structural failure (lol). So as long as you trust Tesla's qc and engineering controls (lmao) there's nothing that looks abhorrent about this part of the cybertruck. ili fucked around with this message at 01:02 on Dec 1, 2023 |

How close is that fully exposed ball joint stud to the tire? Seems like a great place to wedge something in there or sandblast the hell out of the threads that are showing.

The upper control arms are basically a fuse - they give way first before anything tougher to repair gets damaged and most of the weight isnt going them. It's not really terrible, just underdone if you want to launch it off jumps and speedbumps but it's not that far from what you expect to see in big AWD's and light trucks.

ili posted:Nah the dogbones are bolted into a structural bit of frame, you can see the bolt heads in this photo. To be fair, with late model Teslas, almost everything is structural, including the battery pack. That's the FUB (front under body) casting that it's attached to. Bit more info on what they've done here: https://www.teslarati.com/tesla-model-y-casting-redesign-deep-dive/ (except both the front and rear are cast on the cybertruck, I think they've started doing front and rear on the Y and 3 too). That UCA is as thin as what they put on the Y though.
