What about an electric car? Does it also have a clutch that separates the drive from the road?
Would it perhaps make sense to use the clutch of an electric car in a hybrid vehicle that combines both drives in one?

Loading...Now, regardless of which side you're on, the conflict is causing oil prices to skyrocket (so many people are leaving their cars at home), which is quite advantageous for me as a biker, as I now have the roads to myself for riding. Currently, super petrol costs just under €1.90 here.
Heyho 😀 So on April 29th my husband's parents are coming to visit for 10 days. There would be 6 of us in total and we would like to see a few cities (Amsterdam, Munich, Bremen, etc.). We would basically take the train every two days, and now I'm wondering if it might be "better"…
Hello, I'm looking to buy my first car. I've been looking around and found some attractive deals for a 3 Series. The car shouldn't cost more than €3,000, so I'm wondering which engines in which series were good and which weren't (also considering mileage). Thank you very much 🙂
Hello, Unfortunately, I didn't have any luck today. While reversing out, I collided with a pole sideways. I only got a minor scratch on my car. As I was "docking" onto the pole, there was a loud bang. Thinking, "I'll take it to the garage tomorrow to polish that spot," I kept driving, and suddenly…
Hey, I want to build a kart soon. I have a relatively low budget and want to cut costs and keep it as simple as possible. Between petrol and electric, I've already decided on petrol because an electric motor is quiet, but the battery and everything are too expensive. I need help with the axles…
Hello I'm having a problem with my Simson S51 where my hub keeps popping out. The rubber thing in the hub is no longer connected to the wheel hub. The pins in the hub and hub are in top condition. I have an open chain if that helps. Maybe someone has an idea
The only known electric car with clutch is the Kewet Eljet. He didn’t use them at the time. E-motors deliver their full torque from the first revolutions and can be controlled virtually as far as standstill. The uniform torque profile over the rotational speed then also makes a multi-stage transmission obsolete in everyday vehicles, but e-sport cars sometimes have a two-speed transmission for higher speeds.
Very interesting and thank you. There will still be a lot of development in the history of electric cars, I think.
In any case, there is a model of this kind to know well
Since many unfortunately only spread half knowledge here:
An electric car comes out without manual or automatic transmission. Opel has installed a manual transmission in the prototype of Manta E. The reason is nostalgia.
Completely without gear, there are no e-cars in series. For cost reasons, a differential gear is almost always used. Even in Tesla, those are installed to save the copper for a 2nd engine per axle and to simplify cooling.
It is a really very helpful answer. Above all, I think that a circuit with my small half knowledge is very useful. But that’s just a belief in feeling. The electric motors have a greater speed range. No clutch, okay. Thank you.
Is it useful to replace an existing coupling in a hybrid vehicle with an electric drive for starting?
It would then very greatly minimize the wear of the clutch.
in the operation in which I work we also have some E vehicles and those like automatic have only one ‘gas’ – and a brake pedal.
not automatic, no transmission
There is a differential gear.
Thanks for the hint, I improved it.
There are also cars with 2 gears .
Pure electric cars usually have no coupling. Hybrid vehicles as well as petrol engines with automatic transmission have one – usually even more than one clutch.
I also find hybrid vehicles totally attractive.
I’ve got a lot of things here too. Comments, also written among the other questions, you can also go through them.

Well, yeah. A car should always fit the user’s driving behavior. Otherwise you burn unnecessary energy. This will be most obvious when choosing electric or plug-in hybrid. Today’s hybrids are plug-in hybrids. They have an electric motor with high voltage batteries, such as a real electric with a range of 80 to 100 KM. In city traffic, they are supposed to drive purely electric and out of gasoline. To use such a car effectively, you need a certain mix of city and country traffic. If you are driving only city traffic with a plug-in hybrid you have 2 problems: a) you have to constantly load because the range is lower than with a normal e-car and b) the gasoline is never used and is broken. Most who buy a plug_in hybrids and only drive city traffic will probably never load and have an expensively subsidized gasoline that consumes more gasoline than a comparable pure gasoline, as it must carry the weight of the electric motor and the batteries. So if you’re on the road, you should go to an e-car.
Why clutch? An e-car comes out with a gang. Thus, it does not need a gear and thus also no clutch.
Of course it needs a gear. It’s not without gears.
So then the motor pulls with full force every time and there are some electric coils in there. If the motor is applied to the traffic light, the motor has a low basic movement. A very low start-up speed, why shouldn’t this be the case with the electric motor? If it doesn’t turn at all and then the entire start-up load is only on one coil and if it burns through. Nay
If a small basic movement were present at the beginning, then all other tracks would also be loaded, e.g.
So that’s why, nothing for bad.
In any case, I can well imagine that if you have a m6etall core or a ball bearing without oil supply and in all six or nine gears, or how many the cars have today, with 300 km:H drives that things are in 0, not downwards.
I only read about the overall solution Electro I rarely read of technical details so I find my question very well done or suitable.
That an electric motor has in any case a clutch, or a gear, or an oil supply, I don’t know. Probably all electro-professors. Indiscusable. Which materials? Which systems of different manufacturers at what prices? 🤔
They just want to steal my rapeseed tractor 🙄
Point. But where should the technical achievement come from, that this would now be the ideal solution that replaces the previous technology?
I don’t see that. Except for the argument, less dust in densely populated areas.

An e-car does not need a clutch because there is virtually no classical gear, but in the hybrid because of the burner already.
They got automatic. So no clutch
they only have 1 gear, so no clutch
As hybrid have the several gears but automatic circuit
They have no automaticThe electric motor is connected directly to the wheels with a simple reduction gear.
He mentioned hybrid….
With voltage and electricity, which is highly regulated, would it be the ideal part of the kit for every petrol and diesel. It is notWhy? I mean, that would be a good fit. But no one has made any of the manufacturers, all standard couplings. So why?
Okay, I babe michncut focused on the BEV. Hybrid is a mogel pack for me. 😉
I’m not a self-loved snob. Look at your feasts and the wooden box in which you land will be as big as mine.
Then call a loadable current wave. With increasing use of regenerative energies in production and driving operation, this changes, while burning is not possible.
We have been driving with electricity from the roof for almost 1 month. Can you?
No electric. Don’t be a bum drive a burner. After the production of the batteries, an e car has expelled as much co2 as a 10 year old diesel. And as long as the electricity is still largely composed of fossil fuels, it is green on such a car garnix.
Hybrid is the largest beacon that the automotive industry has developed.
E-cars have and do not need coupling because you do not have to change gear and the electric motor works up to 0 rpm.
The change between forward and reverse travel is made electric.
This means that the motor goes directly via the simple (non-shiftable) transmission with differential to the drive shafts and wheels.
Okay, I think that’s logical, which is switched forward and backward, with little effort, but I don’t think it’s as logical, how much gas I give in at the beginning, when I turn up completely, it’s going to drive in the same way, or it’s going to break faster than when I’m getting slowly or there’s a standard solution from Tesla?
Forward and backward is not mechanically switched, the motor simply turns in the other direction.
When you start with the electric car, the motor gets power, then it starts to turn. If you drive “full gas” then you just get more power. The motor itself does not do this, but differential and drive shafts are loaded more strongly than with any car.
What for? The secret is the ability of recuperation, kinetic energy is recovered proportionally by the drive motors and the battery is charged with it. You can’t have a clutch.
That’s what they’d do when they’re recoupling?
However, there is no need for a coupling for purely technical reasons and it is therefore not installed. It is therefore completely superfluous and as a driver of an electric car, by the way, I do not miss it.
Why and when should we even be uncoupled? There is no change of gear, as is known, the engines have a lot of torque from speed 0.
Here https://www.motor-talk.de/blogs/zephy-s-blog/warum-used-one-e-drive-no-shiftable-gear-t6157251.html is explained why one does not need a gearshift in the electric motor. If you don’t need this, you don’t need a clutch, at least in the electric car.
There is no correct coupling for e-cars:
There may be those with tempomat, but no proper coupling.
The only thing that comes close to this would be the energy change, i.e. from forward to reverse. More coupling is not there.
Or do you mean a trailer coupling? That would be possible.
“There may be those with tempomat, but not a proper coupling.”
What does Tempomat have to do with coupling?
The acceleration that acts on the standing car.
Thought experiment: I drive 300 with an electric car, there was nothing there and I go off with ~the same juice at the traffic lights. From now on. This can be the last state of the art ,😁.
Absolutely not.
