Abstract
A skewed-roller brake assembly 10 is provided, including a first rotor disc 12 and a second rotor disc 12. A stator disc 14, positioned between the first and second rotor discs 12, includes a plurality of skewed-roller slots 16 formed through the stator disc 14. A pair of roller elements 20 are positioned within each of the plurality of skewed-roller slots 16 such that a first of the pair of roller elements 21 protrudes from the stator disc 14 in the direction of the first rotor disc 22 and a second of said pair of roller elements 23 protrudes from the stator disc 14 in the direction of the second rotor disc 24. When the first and second rotor discs 12 are moved towards the stator disc 14, the first of the pair of roller elements 21 and the second of the pair of roller elements 23 rotate in concert while transmitting frictional torque to the first rotor disc 12 and the second rotor disc 12 respectively.
