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.

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.
A cone clutch serves the same purpose as a disk or plate clutch; however, instead of mating two spinning disks, the cone clutch uses two conical surfaces to transmit torque by friction. [ 1 ] The cone clutch transfers a higher torque than plate or disk clutches of the same size due to the wedging action and increased surface area.
Diagram of a dry clutch. A dry clutch uses dry friction to transfer power from the input shaft to the output shaft, for example a friction disk presses against a car engine's flywheel by a spring mechanism. The wheels of the vehicle only rotate when the flywheel is in contact with the friction disk.
This is performed by two bands, two multi-disc clutches and a one-way clutch. When the transmission of the motionless vehicle is placed in Drive, the transmission allows the vehicle to move off in first gear, then will change to second and then to third gear based on an increase in road speed.
Last year, the exes jetted off to Costa Rica to spend a kids-free holiday together. Haack is mom to daughter Taylor, 14, and son Brayden, 9, from her first marriage to Tarek El Moussa.
