TRANSMISSION INCLUDING DOG CLUTCH ARRANGEMENT AND METHOD

摘要

A transmission includes a housing, a first shaft rotatably supported relative to the housing, and a second shaft rotatably coupled to the first shaft. A switch-type clutch assembly is movable between an engaged state having a first clutch member coupled to a second clutch member and a disengaged state having the first clutch member separated from the second clutch member. The housing rotates with the first shaft when the switch-type clutch assembly is in the engaged state. A friction clutch is movable between an engaged state having a first friction plate coupled to a second friction plate and a disengaged state having the first frication plate separated from the second frication plate. The second shaft is fixed for rotation with the first shaft via the housing when the switch-type clutch assembly and the friction clutch assembly are both in the engaged state.

主权项

1. A transmission, comprising:
a housing; a first shaft rotatably supported relative to said housing; a second shaft rotatably coupled to said first shaft; a switch-type clutch assembly including a first clutch member fixed for rotation with said first shaft and a second clutch member fixed for rotation with said housing, said switch-type clutch assembly movable between an engaged state having said first clutch member coupled to said second clutch member and a disengaged state having said first clutch member separated from said second clutch member, said housing rotating with said first shaft when said switch-type clutch assembly is in said engaged state; and a friction clutch assembly including a first friction plate fixed for rotation with said housing and a second friction plate fixed for rotation with said second shaft, said friction clutch assembly movable between an engaged state having said first friction plate coupled to said second friction plate and a disengaged state having said first frication plate separated from said second frication plate, said second shaft fixed for rotation with said first shaft via said housing when said switch-type clutch assembly and said friction clutch assembly are both in said engaged state.
