Claims6
In a transmission having dog clutches, each of said dog clutches having a control fork pivotable between a clutching position and a declutching position, a clutch control device comprising:
- an actuator having a body;
- means for translating said body along an axis parallel to pivoting axes of said control forks, wherein said control forks are in at least two axial positions relative to said axis of translation;
- means for rotating said body about said axis of translation;
- and
- at least one pin fixed to said body and having means for cooperating with each of said forks, whereby said at least one pin may translate and rotate to engage one of said control forks and may rotate to pivot said one of said forks between said clutching and declutching positions,
- wherein said translation means comprise:
- a double acting translation cylinder comprising said body;
- hydraulic feed means for said translation cylinder;
- and
- solenoid valve means in said hydraulic feed means.
