What exactly does switching to H4 do?

I was careful not to say anything but spinning - but in 2WD if one tire loses traction neither tire can push the truck and you are stuck. I'm speaking from a strictly mechanical standpoint here, lockers and traction control schemes can change things.

 

While you can have one tire spinning and the other stationary, he is STILL correct that neither is getting [significant] power. It doesn't take much power to spin a wheel that has no traction.

 

If you go out stomp the gas, youre only gonna get one tires that smokes.

 

Wow, TW is full of bullshit, I mean experts.

 

This doesn't really prove anything relevant to the discussion. If you stomp the gas and smoke one tire the truck is still going to accelerate forward with equal power from both wheels. Both the spinning tire and non spinning tire are propelling the truck with equal force in this case. The non spinning tire can only propel the truck with as much force as the kinetic friction coefficient of the spinning, smoking tire will allow.

 

And yet they are still receiving EQUAL power.

 

I see what your saying with equal power. I was thrown off by your original statment about them not being open diffs. I thought you were saying they were locked.

 

power is going the route of least resistance. If your in 2wd and your right rear is in the air. your right rear is going to spin and your not going anywhere. Auto - LSD then comes into play, applies brakes to right rear, dispersing power equally over rear axle

 

Have you not bothered to read? If your right rear is in the air, then only NEGLIGIBLE power is being delivered to it (because it doesn't take much to make it spin), and an EQUAL (still negligible) power is going to the one with traction.

Your explanation about the brakes is also indicative of misunderstanding. It doesn't "redirect" **ANYTHING**. It just holds the wheel so that BOTH can be delivered ALL the power.

On an open differential, BOTH outputs ALWAYS receive EXACTLY the same power!

If you don't believe me, try this little experiment;
Get yourself a piano board. That's what we call a flat board with 4 wheels that you use to move a piano.
Get a JACK STAND.
Position the jack stand ON the piano board, under the RIGHT REAR axle, at a height just enough to keep the wheel off the ground.
Get in the car, release the brake, put it in first gear, and GIVE IT, briefly, with the wheel in the air. Careful not go go over the red line.

What YOU THINK you will observe: wheel spinning.
What you WILL observe: it will move forward. A bit, and very weakly. The forward motion will occur WHILE the raised wheel is accelerating -- since it doesn't take any power to sustain a constant speed. But WHILE that wheel is accelerating, it will deliver some power to the wheel on the ground, and you will get some forward motion.

 

Lol. No need to be a dick. Hes just commenting. I think there is some misunderstanding from both sides of the use of 'power' being distributed. Yes, both tires receive equal power. But for explanation purposes, which toyota uses the same explanation for auto lsd and ATRAC, is that the brakes are applied to the slipping side to allow the tire with traction to push the vehicle.

 

Your confusing open differential with locked differential. A locked differential both wheels have the same amount of power all the time. With open differential the power goes to the wheel with least resistance.

fast forward to 2:10

@tgear.shead You're a fucking idiot! Watch the video posted and see that YOU ARE WRONG!

 

Thats the plan for now once i have the monies. just thought i would ask in case there was something out there i did not know about.

 

I am not confusing anything. You are.
Like I said, when one wheel is in the air, NEGLIGIBLE power is delivered to BOTH. That is why you don't move.

 

Yelling like a FUCKING ASSHOLE doesn't make you right.

As far as the VIDEO goes... wow, you believe everything that you see on youtube? First off, the video is downright WRONG. I don't know if that is a result of whoever made it actually not understanding, or if it was a bad attempt to oversimplify it for simpletons who CAN'T understand how it works.

An open differential ALWAYS delivers EXACTLY the same power to ALL outputs.

When one output doesn't have enough traction to hold the power, it slips. When it slips, you (the driver) regulate the power output by reducing throttle to prevent engine damage due to overrevving. Very little power is being generated, very little power is being delivered -- to ALL of the outputs.

 

Let's try this 1 MORE time. Fast Forward to 3:10

How do you think it helps you to post links to videos that YOU clearly DO NOT UNDERSTAND?

 

You're a douche and are talking shit. You need some meds or something.

 

I will refer you to this;

 

Please enlighten me then because the only thing you've said is that both wheel are getting equal amount of power in an open differential which is terribly wrong. So instead of cussing about how your right and everyone else is wrong why don't you back up your claims and show us. Just because you know how to use the caps lock doesn't mean your right.
