  • Patent number: 10100883
    Abstract: A clutch for selectively preventing rotation of a rotating component may include a first and second pawls pivotable between engagement and disengagement with the rotating component to selectively prevent or allow rotation of the rotating component in one or both directions. An armature moveable between a first and second armature positions may have a common member pivotally connected thereto and engaging the first and second pawls, with a torque spring biasing the common member to rotate toward the first pawl and away from the second pawl. In an intermediate armature position, the common member may disengage the first pawl from the rotating component while engaging the second pawl to allow rotation in one direction while preventing rotation in the opposite direction. In embodiments, a clutch may include a cam actuator rotating to selectively control engagement of the pawls with the rotating component and locking in one or both directions.

  • Patent number: 10099553
    Abstract: A transfer case (26) for translating rotational torque from an engine (22) to first and second differentials (34, 36). A primary shaft (50) is supported in a housing (48) and has an input in communication with the engine (22) and an output in communication with the first differential (34). A secondary shaft (52) is disposed in communication with the second differential (36). A clutch (54) selectively translates torque between the shafts (50, 52) and moves between a first position (54A) wherein torque is translated to the secondary shaft (52), and a second position (54B) wherein torque is interrupted. An actuator (64) with a piston (68) movably supported in a cylinder (66) moves the clutch (54). A lock (70) moves between a locked configuration (70A) engaging the piston (68) to prevent the clutch (54) from moving, and an unlocked configuration (70B) releasing the piston (68) allowing the clutch (54) to move.

  • Patent number: 10094450
    Abstract: A tensioner uses a low rate torsion spring in a first stage and a high rate torsion spring in a second stage to maintain tension in a chain or belt. The first stage is connected to the second stage by a torque coupling. The high rate torsion spring is maintained in an energized state between a ground and a dead stop to store energy and to provide tension under high loads. In some embodiments, the torque coupling is a damper. In other embodiments, the torque coupling is a clutch. A method stores energy in a high rate torsion spring of a tensioner.

  • Patent number: 10087826
    Abstract: An exhaust-gas turbocharger with a compressor with a charge pressure control device. An actuator is provided which moves a control rod arrangement. The control rod arrangement is in turn rotatably connected to a lever. The charge pressure control device is actuated by the lever. A pin is arranged on the lever. The control rod arrangement has a bushing which is pushed onto the pin. The connection between pin and bushing constitutes a rotatable connection for enabling the lever to be actuated by the control rod arrangement. This arrangement is very simple to produce and very simple to assemble because the bushing must merely be pushed onto the pin.
