Winching...

[ldjessee]

I am not a fan of added complexity, but the ability to change gear ratios may prove to be a useful tool for off-roading... but I would need to be convinced.

Might also let them have a slow off-road oriented gears at the low end, but allow for better efficiency the road. (I would need to be shown this)

This is a converted Wrangler... not a production model.

That's basically what it does. Lets you choose the crawl rate mechanically, which also increases the power to the wheels.

It wasn't damage I had in mind. The traction motors and gearing are designed to transmit power to the wheels of the vehicle and to do so at the maximum possible efficiency and that efficiency is chased to a fraction of a percent. To split the power mechanically would require extra gears, clutches, shafts, bearings etc and even while in the "disconnected" mode those components would introduce losses. That's not acceptable here where every watt counts. In addition you can't put a PTO shaft just anywhere. But you can run wire just anywhere.

Think a bit about the heat pump compressor. Why do you think it is driven by a separate electric motor as opposed to using mechanical takeoff from the traction motor as is done in ICE vehicles?

Yep, the more moving/working parts the increased chance there is of wasted efficiency, energy and failure.

I did trades for a stint and what I learned was the less complications - on a roof - ( dormers, valleys, skylights...) the better chance exists of no leaks or problems.

Casted parts for Tesla is a great idea.

As far as I have seen, this is not how Jeep intends for the all electric Wrangler production model to be built. This is a conversion to work as a prototype (and maybe test mule).

I am sure given the history of a diesel jeep and then the all electric Jeep, I could see given that history (and Nikola and the Hummer), I could see them wanting a show worthy concept that actually works, drives around, and is not rendered or a static display mockup.

I am not aware of any deadspace under the cybertruck. between the batteries, vault cover, suspension and storage... unless you mean the storage under the bed and want to use that for the winch...

The Dead space would be between the “penthouse” under the rear seats and the rear motor assembly; as in the space Rivian are using for the gear tunnel in the R1T.
I have a feeling is might be taken up by the tonneau cover, but maybe there’s enough room for another motor and winch spool.

I believe that is where the vault cover stores, so not sure of any dead space in the Cybertruck.

It wasn't an engineering thought process.. it was a Dealer relations thought process... i.e. how are we going to keep our Jeep dealers in business with EVs? I got it, transmission repairs.

 

[Crissa]

Several of the racing bikes have transmissions, too.

While an electric motor has a very broad optimal torque and horsepower curves, they're still a narrower range than the vehicles are used.

Tesla solves this with overlapping optimal curves from multiple motors splined together, but this still limits bottom end torque and top end speed.

AC outlets are already planned. Way more powerful and efficient as Mr.Tesla argued with Edison over a little while back. A Warn Cyberwinch should be a given albeit not cheap. I'm sure this is one of the engineers fun projects at Tesla and/or Warn. I previously said DC outlets on this post. I'm an idiot for not proofreading.

I've found a solution. Working on a full video, but here is a Teaser for now!

That looks like 1/4" steel cable. I hope it's an illusion!

Well, it could be changed to 1/4" Dyneema rope and be a lot stronger.

I prefer Dyneema (or equivalent) rope over wire rope but 1/4" diameter would still be considered undersized for general winching of full-sized pickups. It could be used safely within it's limits in certain scenarios, but it can sometimes be difficult to predict loading depending upon the possibility of unexpected shock loads, making it less suitable for general winching duties.

While Dyneema type ropes are radically stronger by weight than steel ropes, by diameter the difference is minimal.
