Spring guided double cardan joint

Patent, 2022

A double cardan joint assembly including an input universal joint, an output universal joint, and a resilient member disposed between the input universal joint and the output universal joint. The resilient member is positioned between the input universal joint and the output universal joint by attachment to either an arc guard of each universal joint or a cross-member of each universal joint, for example. The resilient member is adapted to center and align the double cardan joint assembly. Thus, the double cardan joint assembly does not necessarily include a conventional aligning ball-joint.
