A permanently engaged starter system for use in a vehicle, with the vehicle including a crankshaft and an engine block, includes a dual-mass flywheel and a permanently engaged starter assembly. The dual-mass flywheel extends along an axis and has an inner diameter portion disposed about and adjacent the axis and an outer diameter portion disposed about the axis such that the inner diameter portion is disposed between the outer diameter portion and the axis. The permanently engaged starter assembly includes a one-way clutch and a ring gear. The one-way clutch extends along the axis and includes an inner member disposed about the axis and an outer member disposed about the inner member. The ring gear is rotatably coupled to the one-way clutch and is adapted to be rotatably coupled to the outer diameter portion of the dual-mass flywheel through the one-way clutch.

An engine including an engine block having a cylinder defining a front of the engine, a blower housing coupled to the engine block and defining a hot half and a cool half opposite the front half, a starter mount assembly coupled to the blower housing and positioned within the cool half, an electric starter motor retained by the starter mount assembly, and a battery mounted to the blower housing and positioned in the cool half. The battery is electrically coupled to the electric starter motor.

A clutch, including: an inner race forming a pocket; an outer race; a pawl including a portion in the pocket; and a cage radially disposed between the inner race and the outer race. The cage includes a radially outer surface segment and a lift off bump stop extending from the surface segment. For a one-way mode, the inner race rotates, with respect to the outer race, only in one circumferential direction. For a first phase of the one-way mode, the inner race rotates in the circumferential direction and the pawl is arranged to be in contact with the outer race and free of contact with the lift off bump stop. For a second phase of the one-way mode: the inner race rotates in the first circumferential direction; and the pawl is arranged to be in contact with the lift off bump stop and free of contact with the outer race.

A lubricating fluid damped anti-rotational system is provided comprising a pawl carrier having an axis of rotation and a radial aperture, a pawl pivotably mounted to the pawl carrier on a pivot joint, the pawl having a contact portion and a counterweight portion, a lubricating fluid jet configured to propel a lubricating fluid through the radial aperture toward the contact portion.

A dynamic vibration absorber is configured to be attached to a rotary member. The dynamic vibration absorber includes a base member, a mass body, and a torque limiting part. The base member is rotatably disposed. The mass body is attached to the base member so as to be rotatable relatively thereto. The torque limiting part limits transmission of a torque to be inputted into the base member from the rotary member.

A clutch apparatus or system for a vehicle drive train for transmitting torque between the vehicle's engine and gear change gearbox. Three interoperative clutch members are provided in the apparatus. The three clutch members cooperate with at least two clutch plates, a pressure-receiving plate, a clutch pressure plate, a plurality of clutch pressure springs, and a setting device, which is provided between the second clutch member and the third clutch member, for setting a back torque between the third clutch member and the first clutch member by an axial displacement of the third clutch member relative to the second clutch member. An engagement device is provided between the second clutch member and the third clutch member for accomplishing a releasable engagement position, between the second clutch member and the third clutch member, as a function of the rotational angular velocity of the third clutch member.
