20110065340, Mar 17, 2011

Filed:

Oct 29, 2007

Appl. No.:

11/978283

Inventors:

Daniel P. Klawitter - Beaver Dam WI, US
Gregory C. Bowlby - Oshkosh WI, US

International Classification:

B63H 20/08

US Classification:

440 53

Abstract:

A steering system for an outboard motor uses bearing support structures to attach a steering mechanism to a trim/tilt bracket which is attachable to a transom of a marine vessel. The steering mechanism comprises upper and lower attachment brackets which are permanently attached to a tubular member extending therebetween. The tubular member is attached to the bracket through the use of two bearing support structures in combination with two pairs of split bearings.

Appl. No.:

14/868752

Inventors:

- Dearborn MI, US
Gregory Bowlby - Ann Arbor MI, US

International Classification:

F16D 35/02
F01P 5/12

Abstract:

A liquid cooled viscous fan clutch transfers torque from a driving plate driven by an engine crankshaft to a driven plate connected to a cooling fan. Heat generated in a working fluid is transferred to a second fluid, such as engine coolant or transmission fluid, flowing between the driven plate and a stationary housing. A controllable valve may be closed to block circulation of working fluid, trapping working fluid in a reservoir, to disengage the clutch. Rotation of the driven plate provides the motive force to circulate the coolant or transmission fluid.

International Classification:

F16D 35/02

Abstract:

A liquid cooled viscous fan clutch transfers torque from a driving plate driven by an engine crankshaft to a driven plate connected to a cooling fan. Heat generated in a working fluid is transferred to a second fluid, such as engine coolant or transmission fluid, flowing through a cooling jacket. The cooling jacket is located in a stationary housing which may be fixed to the engine. The working fluid circulates through a working zone, a passageway in the stationary housing, and a passageway in the driving plate. Rotation of the driving plate provides the motive force to circulate the fluid, independent of the rotation speed of the driven plate. A controllable valve may be closed to block circulation, trapping working fluid in a reservoir, to disengage the clutch.
