Damped isolator
View Patent ↗A damped isolator comprising a first hub, a first pulley connected to the first hub, a bearing carrier connected to the first hub, an elastomeric member engaged with the first hub, a one-way clutch engaged with the elastomeric member, a bearing received by the bearing carrier, a second hub engaged with the one-way clutch and the bearing, and a second pulley connected to the second hub.
1. A damped isolator comprising:
a first hub ( 40 );
a first pulley ( 51 ) connected to the first hub;
a bearing carrier ( 60 ) connected to the first hub;
a first elastomeric member ( 30 ) connected to the first hub;
a one-way clutch ( 20 );
a bearing ( 72 ) received by the bearing carrier;
a carrier member ( 61 ) for receiving the one-way clutch;
the carrier member engaged with the first hub through the first elastomeric member, whereby a vibration transmitted from the first hub to the one-way clutch is damped;
a second hub ( 70 ) engaged with the one-way clutch and the bearing; and
a second pulley ( 73 ) connected to the second hub.
2. The damped isolator as in claim 1 further comprising an inertia member connected to the first pulley.
3. The damped isolator as in claim 1 , wherein the first pulley and the second pulley comprise a multi-ribbed profile.
4. The damped isolator as in claim 1 further comprising a seal cooperatively engaged with the carrier member.
5. The damped isolator as in claim 1 further comprising a second elastomeric member disposed between the first pulley and the first hub.
6. A damped isolator comprising:
a first hub connected to a first pulley;
an inertia member connected to the first pulley;
a second hub connected to a second pulley;
a one-way clutch operably disposed between the first hub and the second hub, and
a first elastomeric member operably disposed between the first hub and the one-way clutch, whereby a vibration transmitted from the first hub to the one-way clutch is damped.
7. The damped isolator as in claim 6 further comprising:
a carrier member for receiving the one-way clutch; and
the carrier member connected to the first hub.
8. The damped isolator as in claim 6 , wherein the first pulley and the second pulley comprise a multi-ribbed profile.
9. The damped isolator as in claim 6 further comprising a seal cooperatively engaged with the carrier member.
10. The damped isolator as in claim 6 further comprising a second elastomeric member disposed between the first pulley and the first hub.
