Separate Resilient Member Between Clutch Element And Its Shaft Patents (Class 192/55.3)
  • Patent number: 8900094
    Abstract: A powertrain includes an engine having a crankshaft, a transmission having an input member, and a damper operatively interconnecting the input member and the crankshaft to transmit torque from the crankshaft to the input member. An electric motor/generator is operatively connected to the transmission input member to selectively transmit torque thereto. A damper bypass system is operatively connected to the crankshaft and the input member. The damper bypass system is configured not to transfer torque from the crankshaft to the input member, but transmits torque from the input member to the crankshaft in response to input member torque exceeding crankshaft torque.

  • Patent number: 8899201
    Abstract: A starting system for a hybrid vehicle includes an internal combustion engine having a crankshaft rotatably supported within an engine block. The starting system includes a pinion gear driven by a starter motor, a drive plate having a set of teeth in constant meshed engagement with the pinion gear, and a one-way clutch. The one-way clutch is adapted to selectively drivingly interconnect the drive plate and the crankshaft. The clutch includes an inner race adapted to be fixed for rotation with the crankshaft, an outer race coupled for rotation with the drive plate, and a plurality of roller elements positioned radially therebetween. A fastener couples the drive plate to the outer race and compresses an elastomeric damper between the drive plate and the outer race.

  • Patent number: 8172055
    Abstract: A one-way clutch is proposed which includes an outer race having a radially inner surface in which a plurality of pockets are formed. Rollers are each received in one of the pockets. Wedge-shaped spaces are defined between respective cam surfaces of the pockets and a shaft inserted through the outer race. When the shaft rotates in one direction, the rollers are wedged into the narrow ends of the respective wedge-shaped spaces, thereby locking the clutch. When the shaft rotates in the opposite direction, the rollers move toward the wide ends of the wedge-shaped spaces, thereby unlocking the clutch. The casing includes a main body and a cylindrical member fitted in the main body and made of an elastic synthetic resin. The outer race is fitted in the cylindrical member.

  • Patent number: 7717249
    Abstract: An electromagnetic gear-clutch assembly (1) is disclosed. The device comprises a gear (10) having grooves (10c) that open inwardly toward the axis and extend axially. A hub (12) is located within the gear (10) where it is capable of rotating within the gear (10). The hub (12) has grooves (12k) that open outwardly away from the axis and extend axially. Keys (17) are located within the grooves (12k) of the hub (12) and are capable of moving radially toward and away from the axis, the arrangement being such that when the keys (17) are permitted to move away from the axis, at least one will enter one of the grooves (10c) in the gear (10) to couple the gear (10) and huh (12) so that they will rotate in unison. The device also comprises an actuator assembly (3) for effecting radial displacement of the keys (17).

  • Patent number: 6578688
    Abstract: An automotive air conditioning compressor clutch eliminates all rivets and utilizes only one return spring. A hub with multiple radial teeth closely fitting into armature openings supports the armature plate concentric and parallel to a pulley friction disk. The armature is free to slide relative to the hub as the return spring is compressed. The thrust areas between the hub teeth and armature are large, which reduces compressive stress. The lower stress reduces the wear rate for both the all-metal and rubber torque cushion versions of the clutch.

  • Patent number: 6449798
    Abstract: A multi-function apparatus for controlling various functions of a liftgate of an automotive vehicle. The apparatus includes an elastomeric member which is operably disposed in connection with a gear which imparts a driving force to a drive shaft of a window wiper member. The elastomeric member, in one embodiment, is a coiled spring which allows movement between the drive shaft and the gear driving the drive shaft in the event the wiper becomes frozen to the window of the vehicle or otherwise immovable. In this manner various other functions can be carried out by the apparatus regardless if the wiper becomes temporarily immobilized.

  • Patent number: 6216837
    Abstract: The rotary housing of a hydrokinetic torque converter, which can be utilized in the power train of a motor vehicle—for example, in conjunction with a continuously variable transmission—contains a torque monitoring device which is installed in such a way that it does not take up any, or any appreciable, additional space, especially in the axial direction of the housing. The torque monitoring device can serve to transmit torque between the lockup clutch and the output element of the torque converter. Additional features reside in the provision, configuration and manner of mounting of an auxiliary mass, and in the provision of a member for centering the piston of the lockup clutch in the housing as well as a member for centering the housing on the output element of a prime mover.
