Abstract
A speed-responsive engaging mechanism adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of cam surfaces thereon formed in apertures in the discs with a series of friction shoe assemblies mounted in the apertures in engagement with the cam surfaces. The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the cam means induces a wedging engagement of the shoes with the impeller member. Spring means are provided to retain the shoe assemblies in the apertures, and a roller mechanism may be provided in each shoe assembly to provide relatively frictionless relative movement between the cam surfaces and the shoe assemblies. Means are provided between the roller and cam to limit the amount of torque which can be developed by the wedging action of the cam and roller mechanism.
