ABSTRACT:
A constant velocity, "Tri-Pot" type joint comprises first and second members respectively rotatable about first and second axes and a coupling for connecting the first and second members. The coupling comprises three trunnions rotatable with the first member. The trunnions have respective radial axes extending radially from and perpendicular to the first rotation axis and intersecting the first axis at a common intersecting point. The coupling also comprises rods connecting the trunnions to the second member, and laminated elastomeric bearings, disposed about the trunnions for carrying in compression torque transmitted between the first and second members and for carrying in shear axial misalignment of the first and second members and relative angular motion between the first and second members about the common intersecting point. In the preferred embodiment of the plunging joint the coupling includes laminated elastomeric bearings for accommodating in shear a telescoping motion applied to one of the members along its rotation axis with respect to the other of the members; and of the fixed joint includes laminated elastomeric bearings for carrying a telescoping load in compression.
