Abstract
A harmonic balancer assembly is provided including a drive plate adapted to be attached to a crankshaft or other drive shaft. A first circumferentially extending elastomeric ring is connected to an axial face of the drive plate. An inertia ring is provided which also includes an axial face that is connected to the first elastomeric ring. A drive element can be connected to or engaged with the inertia ring in order to transmit torque from the drive plate to a further element in a drive train. The inertia ring can be connected to a pulley, a torque converter, or other transmission element in order to, for example, transfer torque from a crankshaft to a further transmission component or to transfer torque to a separate power take off.
Claims17
A harmonic balancer assembly, comprising:
- a drive plate adapted to be attached to a crankshaft;
- a first circumferentially extending elastomeric ring connected to an axial face of the drive plate;
- an inertia ring having an axial face connected to the first elastomeric ring;
- a support plate connected to the drive plate;
- and
- a second circumferentially extending elastomeric ring connected to an opposite axial face of the inertia ring from the first elastomeric ring, and the second elastomeric ring is connected to an axial face of the support plate on an opposite side from the inertia ring,
- the drive plate, the first elastomeric ring, and the inertia ring axially overlap in a connection area, and
- the support plate includes centering tabs for the inertia ring.
