What are manual transmission synchronizers? Newsletter Signup First Name: As an output pulley , the driven pulley transfers energy to the driveshaft. One of the pulleys, known as the drive pulley or driving pulley , is connected to the crankshaft of the engine.

How CVTs Work

The combinations of gears are carefully chosen so the engine can remain in its best rev range for either power, torque turning force or efficiency. The second pulley is called the driven pulley because the first pulley is turning it. These flexible belts are composed of several typically nine or 12 thin bands of steel that hold together high-strength, bow-tie-shaped pieces of metal.

How an automatic gearbox works A normal automatic gearbox uses gears to match engine speed to road speed.

This feels and sounds like the clutch is slipping in the car, or an automatic transmission gone wrong. And automakers also go to a lot of trouble to smooth out the gearchanges as well as make them faster. The result is a smoother, more efficient and quicker drive than an normal automatic.

What this means for the driver is that the engine can go directly to the best rev range for a given situation. In all of these applications, the transmissions have relied on high-density rubber belts, which can slip and stretch, thereby reducing their efficiency.
