  2. Sprag clutch - Wikipedia

    en.wikipedia.org/wiki/Sprag_clutch

    One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.

  3. Slipper clutch - Wikipedia

    en.wikipedia.org/wiki/Slipper_clutch

    When a back torque comes from the transmission, the splined hub slides up the bearing ramps, disconnecting from the clutch plates and allowing a limited slip between input and output. This type of clutch is designed to partially disengage or "slip" when the rear wheel tries to drive the engine faster than it would run under its own power.

  4. Hydramatic - Wikipedia

    en.wikipedia.org/wiki/Hydramatic

    The Controlled-Coupling Hydra-Matic incorporated a secondary fluid coupling and a pair of sprag clutch in place of the former friction clutch and brake bands, shifting in part by alternately draining and filling the secondary coupling. It was a later version of GM's "dual-range Hydra-Matic", first introduced in some 1952 models.

  5. Centrifugal clutch - Wikipedia

    A chainsaw's clutch. The chain wraps around a sprocket behind the clutch that turns with the outer drum. The input of the clutch is connected to the engine crankshaft while the output may drive a shaft, chain, or belt. As engine revolutions per minute increase, weighted arms in the clutch swing outward and force the clutch to engage. The most ...

  7. Freewheel - Wikipedia

    en.wikipedia.org/wiki/Freewheel

    Citroën combined a freewheel and a centrifugal clutch to make the so-called 'TraffiClutch', which let the driver start, stop, and change the lower gears without using the clutch. This was an option on Citroën 2CVs and its derivatives and, as the name implied, was marketed as a benefit for driving in congested urban areas.

  8. The Overdue, Under-Told Story Of The Clitoris

    projects.huffingtonpost.com/projects/cliteracy/intro

    From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.

  9. Electromagnetic clutches and brakes - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_clutches...

    Based upon the size of the clutch or brake, the speed and the inertia, wear rates will differ. For example, a machine that was running at 500 rpm with a clutch and is now sped up to 1000 rpm would have its wear rate significantly increased because the amount of energy required to start the same amount of inertia is a lot higher at the higher speed.
