Abstract
A transmission for a marine propulsion system uses a cone clutch in such a way that, when in a forward gear position, torque is transmitted from an input shaft, or driving shaft, to an output shaft, or driven shaft, solely through the cone clutch. When in forward gear position, driving torque between the driving and driven shafts is not transmitted through any gear teeth. When in reverse gear position, torque is transmitted through an assembly of the bevel gears.
Claims19
A transmission for a marine propulsion system, comprising:
- a first shaft supported for rotation about a first axis;
- a second shaft supported for rotation about a second axis, said first and second axes being generally parallel with each other;
- and
- a clutch which is alternately movable into first position and second positions, said first position disconnecting said clutch from torque transmitting association with said first and second shafts and disconnecting said first and second shafts from torque transmitting association with each other, said second position connecting said clutch in torque transmitting association between said first and second shafts with torque being transferred from said first shaft to said second shaft solely through said clutch.
A transmission for a marine propulsion system, comprising:
- a driving shaft supported for rotation about a first axis;
- a driven shaft supported for rotation about a second axis, said first and driven shafts being generally coaxial with each other;
- and
- a clutch which is alternately movable into first position and second positions, said first position disconnecting said clutch from torque transmitting association with said first and driven shafts and disconnecting said first and driven shafts from torque transmitting association with each other, said second position connecting said clutch in torque transmitting association between said first and driven shafts with torque being transferred from said driving shaft to said driven shaft solely through said clutch.
A transmission for a marine propulsion system, comprising:
- a driving shaft supported for rotation about a first axis;
- a driven shaft supported for rotation about a second axis, said first and driven shafts being generally coaxial with each other;
- a cone clutch which is alternately movable into first position and second positions, said first position disconnecting said cone clutch from torque transmitting association with said first and driven shafts and disconnecting said first and driven shafts from torque transmitting association with each other, said second position connecting said cone clutch in torque transmitting association between said first and driven shafts with torque being transferred from said driving shaft to said driven shaft solely through said cone clutch;
- a first bevel gear attached to said driving shaft and rotatable about said first axis;
- a second bevel gear which is rotatable about said second axis;
- and
- an intermediate bevel gear disposed in gear tooth meshing association between said first and second bevel gears.
