An elastic coupling comprises an outer ring and a hub. A plurality of radially extending stacks of leaf springs are attached to the outer ring and engage axially extending recesses in the hub. Each leaf spring comprises a set of radially extending axially adjacent coplanar strips in arrangement, namely of one or more central strips and axially outer strips on both sides of the central strips and having smaller width than the central strips. A continuous thin and flexible sheet metal plate covers the various strips and closes the gaps therebetween. Intermediate pieces are provided between the leaf springs along the inner surface of the outer ring. The cavity defined by outer ring, hub and cover plates on each end of the outer ring is sealed and filled with damping liquid. Sealing ledges are provided between the intermediate pieces and the hub to subdivide the cavity into chambers which are, in turn, subdivided by the leaf springs. Connecting passages with restrictors interconnect the chambers formed. The surfaces of the intermediate pieces facing the leaf springs are convex to support the leaf springs upon application of excessive torque. The stacks of leaf springs consist of long and short strips, only the long ones engaging the recesses in the hub. Pistons guided in the intermediate pieces abut short strips of adjacent leaf spring arrangements to make sure that all strips contribute to the torque transmission with both directions of rotations. Various modes of mounting the leaf springs are disclosed.
In an elastic coupling of the type including a first coupling member having a radially outer ring, a radially inner second coupling member having a plurality of recesses in its peripheral surface, and a plurality of substantially radially extending leaf spring means having radially inner and outer ends, said leaf spring means being attached at their outer ends to said first coupling member and extending with their free inner ends into said recesses, each of said leaf spring means having a plurality of axially adjacent strips, the improvement wherein each of the leaf spring means comprises:
An elastic coupling comprising:
In an elastic coupling of the type including a first coupling member, a second coupling member, a plurality of substantially radially extending leaf spring means connecting said first and second coupling members, said leaf spring means being comprised of a stack of spring leaves, the peripherally outer leaves being shorter than the peripherally inner leaves, and a plurality of intermediate pieces located between adjacent leaf spring means, the improvement comprising:
In an elastic coupling of the type including a first coupling member having a radially outer ring, a radially inner second coupling member, a plurality of substantially radially extending leaf spring means connecting said first and second coupling members, a cover member closing each end of said outer ring, and intermediate pieces between said leaf spring means sealingly engaging said first and second coupling members so that the cavity defined by said first and second coupling members and said cover members is divided into chambers, the improvement which comprises:
An elastic coupling comprising:
