Patent ID: 8393973

Claim:
A coupling element for connection between a drive member and a driven member for transmitting torque, the element comprising: at least two similar part-circularly arcuate coupling bodies each formed by an arcuate row of elastomeric segments alternating with and vulcanized to rigid elasticity-limiting elements, each row terminating at two respective end parts at least one of which is formed with an axially or radially throughgoing hole for attachment to the drive and driven members, two of the end parts of different rows being adjacent and in direct engagement with each other in a closed position of the coupling element with the rows forming a closed circle centered on an element axis; and a hinge engaged between the two adjacent end parts for pivotal movement of the part-circular coupling bodies about a hinge axis parallel to the element axis between the closed position and an open position with the two adjacent end parts substantially out of engagement with each other.
