ABSTRACT:
A coil for a dynamic eddy current braking system affixed to the lower half of a vehicle wheel by two steel, yoke-shaped, end supports joined by parallel rectilinear arms, with the end supports spaced for clearance from the coil and along with thin non-magnetic sheets defining free enclosures around the coil ends, the supports having holes to inject an elastomer into the free enclosures. Seals limit the elastomer to the flat portions of the coils and plates in the zone of injection of the elastomer are immobilized in relation to the support parallel to rectilinear arms but separable from the inner wall of the support to permit thermal expansion and contraction of the coil and elastomer in the support without loss of the transmission of forces to the support occurring in the course of braking and without exaggerated transfer of forces to the support in the case of considerable heating or cooling and without detachment of the elastomer in the case of a very considerable drop in ambient temperature.
