Abstract
A motor vehicle transmission assembly is provided that includes a dampening component configured to reduce at least one of noise and vibration within the transmission assembly. In some versions, the dampening component is disposed between first and second transmission components, and the dampening component may be fixed to and/or abutting one of the transmission components. The dampening component may comprise a dampening layer disposed between a pair of outer layers. In some versions, the dampening component has a metallic portion and a non-metallic portion.
Claims18
A motor vehicle transmission assembly comprising:
- a first transmission component;
- a second transmission component, the second transmission component being one of a clutch hub, a clutch housing, a gear, a case, a support, and a shaft;
- a dampening component disposed between the first and second transmission components, the dampening component being configured to reduce at least one of noise and vibration within the transmission assembly, the dampening component contacting the first transmission component and the second transmission component, the dampening component comprising a metallic portion and a non-metallic portion, the transmission assembly being configured to transfer torque between the first and second transmission components through the dampening component, the dampening component being arranged as at least one of the following:
- A) the dampening component abutting the second transmission component and B) the dampening component being fixed to the second transmission component;
- and
- a plurality of interleaved clutch plates configured to selectively transfer torque within the transmission assembly, the dampening component being configured to reduce noise created by the plurality of interleaved clutch plates.
A torque transmitting assembly for use in an automotive transmission, the torque transmitting assembly comprising:
- a plurality of interleaved clutch plates configured to selectively transfer torque;
- a dampening component detached from the plurality of interleaved clutch plates, the dampening component configured to reduce at least one of noise and vibration created by the plurality of interleaved clutch plates, the dampening component comprising a dampening layer disposed between a pair of outer layers, and wherein an outer layer of the pair of outer layers contacts each of a first transmission component and a second transmission component, the dampening layer being free from direct contact with the first and second transmission components.
