  • Patent number: 11859557
    Abstract: A generator drive disconnect device comprising a drive transfer means (100) having a connected configuration, and a disconnected configuration. The disconnect device further comprises a disconnect mechanism, configured to move the drive transfer means from the connected configuration to the disconnected configuration, and a latch mechanism configured to the hold the drive transfer means in the disconnected configuration. The latch mechanism includes a latch member, which is moveable between a retracted position and an extended position, and a biasing mechanism. The biasing mechanism is configured to generate a biasing force to bias the latch member towards the extended position and to apply a reaction force to the latch member to resist movement of the latch member towards the retracted position, the reaction force having a magnitude which increases as a function of the distance of the latch member from the retracted position.

  • Patent number: 10914346
    Abstract: A clutch claw applied to a clutch structure having a rotating shaft includes a claw portion, a base portion and at least two elastic portions. The base portion is opposite to the claw portion and has a peripheral edge. The claw portion and the base portion are coaxially disposed on the rotating shaft. Each elastic portion is at least partly disposed around part of the claw portion to provide elastic force. Each elastic portion has a first end and a second end. The first end is connected with the base portion and extended from the peripheral edge, the second end is connected with the claw portion, and there is at least one bent section between the first end and the second end. Therefore, the collision damage is prevented, and the impact and friction generated when the clutch claw is instantaneously rotated is avoided, thereby achieving the advantage of reducing noise.

    Abstract: The present disclosure provides a disconnect mechanism for removably coupling an input member and an output member to one another. The mechanism includes a drive member configured to be rotationally driven and a driven member rotationally coupled to the drive member. A collar is rotatably coupled to the driven member, where rotation of the drive member induces rotational and longitudinal movement of the collar along the shaft. The mechanism further includes a coupler member coupled to the collar such that the coupler member is adapted to be removably coupled to the input member and output member. As the collar moves along the longitudinal shaft, the coupler member moves longitudinally between a first position in which the input member and output member are coupled and a second position in which the input member and output member are decoupled from one another.

  • Publication number: 20110108384
    Abstract: The invention relates to a positively engaging shifting element which can be hydraulically or pneumatically actuated, comprising a hydraulically or pneumatically actuatable piston (I) having a piston compartment (2) containing a hydraulic medium or pressure medium, a jaw (3) having a dog-type gearing (4) and a mating jaw (5) with which the dog-type gearing (4) meshes when engaged. The engaging speed of the jaw (3) can be increased by decoupling the jaw (3) from the hydraulic or pneumatic volume flow when the jaws (3) and (5) are in a tooth butt position in relation to each other and by pretensioning the jaw (3) by means of a mechanical device (6) that is actively connected to the piston (I). The gap between the jaws, i.e. the window into which the jaw (3) can be engaged is maintained as narrow as possible in order for a tooth butt position of the jaws (3) and (5) in relation to each other being highly probable when the shift element is applied.
