Abstract
Several embodiments of improved detent devices for elements such as dog clutches. In each embodiment, the detent includes a holding detent for holding the dog clutch in a neutral position and an accelerating detent for accelerating the dog clutch element to its engaged position. In each embodiment, the accelerating detent is effective before the holding detent has been fully released. In some embodiments, the dog clutch element is axially movable and in other embodiments it is rotatable.
Claims32
A detent mechanism for dog clutches or the like comprising a first member and a second member juxtaposed to each other and supported for relative movement, said first member having a detent recess adapted to be engaged by a detent, a first detent carried by said second member and biased to engage said recess for releasably restraining said members against relative movement, said first member further having a cam surface formed thereon spaced from said detent recess, and a second detent carried by said second member and biased to engage said cam surface for applying a thrust to effect relative movement between said members, the means for biasing the first and second detents comprising a common spring.
In a shifting mechanism for a dog clutch or the like having a shifting element movable from a disengaged position to an engaged position and holding detent means comprising a first detent member and cooperating first cam surface for retaining said shifting element in said disengaged position, the improvement comprising accelerating detent means comprising a second detent member and a cooperating second cam surface for effecting a force upon said shifting element in its direction of movement from its disengaged position to its engaged position and a single spring acting on both of said detent members.
In a shifting mechanism for a dog clutch or the like having a shifting element movable from a disengaged position to an engaged position and holding means movable between a released position and an engaged position for retaining said shifting element in its disengaged position, said holding means beng movable from its engaged position to its disengaged position in response to a predetermined movement of said shifting element from its disengaged position to its engaged position, the improvement comprising accelerating means for exerting a force upon said shifting means in the direction of its movement from its disengaged position to its engaged position and before said holding means has moved to its disengaged position and a single spring yieldably urging both said holding means toward its engaged position and said accelerating means in its force applying direction.
