How a Differential Works

Автокөліктер мен көлік құралдары

Here's how a differential works on a car!
The differential allows for a difference of rotation between two wheels on the same axle. This will allow a vehicle to turn corners without binding the axle or scrubbing tires.
On front wheel drive vehicles, the differential is often integrated into the transmission assembly. On rear wheel drive vehicles, power is sent through a rotating drive shaft to the rear differential assembly, before being sent out to the wheels through the CV Axle.
The differential consists of a large ring gear (or drive gear) a small pinion gear and small planet gears (spider gears) in the differential housing. When both wheels are moving at the same speed and direction (i.e. vehicle moving straight ahead) the pinion gear rotates the ring gear, which rotates the differential housing and thus each CV axle. When there's a difference in wheel speed, the spider gears start to mesh with each other, allowing one wheel to turn at a different speed than the other.
In this video, an open differential from a 2004 G35 is completely taken apart and analyzed. Other types of differentials include the locking differential and limited slip differential, which aid the disadvantages of the open differential by locking or limiting wheel slip on slippery surfaces.

    Very concise, yet detailed at the same time. Excellent video for learning and revision any time one's memory needs refreshing points. Differential consists of a set of gears that operate together on the drive wheel of the vehicles to ensure that the inner and outer wheels of a vehicle rotate at different speeds in the same period of time, as they should, when a vehicle is making a turn, due to the difference in the distances covered by the wheels when a vehicle is turning. The purposes of the different gears that make up the differential assembly are easy to understand and remember. Knowing and remember about the differential makes one know and remember that the the left and right wheels do not rotate on a single solid shaft, but that the differential assembly casing is what connects them, and that the right and left wheel shafts actually terminate in gears.

    I have watched dozens of KZread tutorials on how the various parts of a vehicle works. Each video I watch, someone explains a tiny thing just a little better than someone else. I thought I knew how a limited slip differential worked, but was always unsure why it was called "limited slip". Today, I learned it is the clutch pack that slips a bit allowing differential speeds between the axles, thus giving its name. And this is coming from someone who has front and rear locking differentials on a Tacoma.

  • @jessequentin4441
    @jessequentin44412 жыл бұрын

    Excellent video. Such an ingenious yet simple gearset. I once heard someone say "an open differential applies the same amount of torque to both wheels at all times". Obviously that doesn't explain how a differential works entirely, but I think it is true and can help understand why the wheels are able to turn at different speeds while going through turns, and why (when you're stuck) the wheel with no traction spins while the other remains stationary.

    An excellent video. I like the description of the most likely failure points (breather valve, seals, bearings, bushings) at 1:50 and 7:10. The trade-off between acceleration and top speed described at 6:25 is interesting. On a motorcycle, the rear sprocket can be replaced with a larger sprocket to increase acceleration at the expense of top speed.

    This is great, thanks a ton! One question, do you have to pull the 3rd from the vehicle to remove the rear carrier assembly? I'm needing to swap mine on my 93 geo tracker and it seems to me that you necessarily wouldn't if you remove the cover of the housing?
