  • Ribbed power-transmission belt
    Patent number: 8152666
    Abstract: A power transmission belt, in particular for a motor vehicle and presenting at least V-ribs having flat side faces and rounded ridges, wherein the ridges present a convex curvilinear profile having a mean radius of curvature greater than 1 mm and less than or equal to 1.5 mm.
    Type: Grant
    Filed: November 12, 2003
    Date of Patent: April 10, 2012
    Assignee: Hutchinson
    Inventors: Hervé Varin, Willy Bourdeau
  • Decoupling element of deformable material in a power transmission system
    Patent number: 7244185
    Abstract: The invention seeks to improve the transfer function of drive devices such as pulleys and other coupling means, and it proposes creating zones of shear in the inserted deformable material forming a decoupling element. In an embodiment, the decoupling element is made in the form of a ring (2) presenting at least one meshing face (21e, 21i) complementary to a corresponding meshing face (31, 41) formed on the facing support (3, 4), the meshing projections (2e, 2i, 3e, 4i) engaging in one another to take up power transmission torque by working in shear by being blocked against each other during rotation. The invention is applicable to all drive devices including a filtering, damping, or absorbing element, e.g. for use in the automotive industry.
