ABSTRACT:
A drive mechanism for an automotive transmission wherein a hydrodynamic drive unit and a friction drive unit are arranged for parallel independent drives. The friction drive unit is maintained in a slipping drive condition to control a predetermined slip in the hydrodynamic drive unit. The slip speed of the friction drive unit is controlled by an engagement force thereon, which force is determined by fluid flow through a variable area passage. The passage opening is responsive to the speed of the input and output members of the drive mechanism in direct relation with one member and a proportional relation with the other member.
