Differential Gear In Rear Axle

02/18/2007 11:36 AM

How the bevel gear in differential transmits the power to the outer wheel than the inner wheel while turning corners? Which makes it negotiate corners?

"HOW THE BEVEL GEAR IN DIFFRENTIAL TRANSMITS THE POWER TO THE OUTER WHEEL THAN THE INNER WHEEL WHILE TURNING CORNERS.WHICH MAKES IT NEGOTIATE CORNERS."

See How Stuff Works, Differential Gear:

<http://auto.howstuffworks.com/differential.htm>

They can explain it better than I.

There are four bevel gears in the carrier in the differential.The carrier is turned by the driveshaft,thru a ring and pinnion gear. Back to the four bevel gears, two of the bevel gears are mounted on opposite sides of the carrier on a shaft that turns with the carrier. The other two gears are mounted between the first two, on the inboard ends of the axel shafts.when the axel is going straight the bevel gears don't turn against each other,the two that are mounted to the carrier (as the carrier spins)drive the two bevel gears on the axels evenly. When you turn a corner the wheel on the inside of the turn has a shorter distance to travel so the bevel gears turn against each other allowing one wheel to turn slower than the other. The same thing happens when you loose traction with one wheel (it spins and the other doesn't get any power) (except in the case of a limited slip differential ,but that is another kettle of fish)

Amazing how the rather simpler of things mechanical so often lead to multiplicity of words. With a 3-d tangible model, differentials are certainly quick-and-easy to (visualize and) understand beasts; the "how things work" animation (when you get to it) is good, too, a distant second...because you still get the profusion of words by the 100s/1000s to answer the questions you weren't asking--which, was, how is slippage accomplished to allow driven wheels to turn at different speeds or in opposite directions?

Anyway, now that I've been put in mind of the see-thru model (how it works in plain sight) car chassis (some might call it a toy) I learned from so many years ago...well, I'm wondering: where could models of that kind be found today? Today when hands are meant to be on keyboards and not on actual things? Anyone know?

In the UK we have a build it toy called Technical Lego.

Gears, Axles,and Drive Trains conectable and in view in clear perspex modules, a must for any budding engineer
