Arc coil spring configuration
09657808 · 2017-05-23 · ·

Arc coil springs utilize coil spring wire formed in a substantially trapezoidal or other shape such that when bottomed, the side surfaces of the coil abut and carry the bottoming load. The angles of the sidewalls of the substantially trapezoidal cross section wire are preferably coincident with lines of radius when the spring is installed in an arc in a clutch, damper or flywheel. The radius of the outer surface of the arc coil spring wire is matched to the radius of the inner surface of the guide or housing so that the area of contact is large.
