ABSTRACT:
Differential gear sets and planetary gear sets in combination with sets of corresponding radially distributed helical surfaces in drive couplings such as cone clutches. The helical surfaces allow axial movement of the cone members of a clutch selectively into engagement with either of two mating cone members thereby enabling an output member to be selectively driven bidirectionally.
