Filed:

Nov 28, 2005

Appl. No.:

11/287780

Inventors:

James Barickman - Erie PA, US
Ulrich Kuester - Spring Lake MI, US
Nicola Freri - Mazzano, IT

International Classification:

F16F 1/44

US Classification:

267293000, 267136000

Abstract:

The vehicle cab suspension radial damped bushing includes a nonelastomeric rigid outer member having an outer member center bore with an outer member center axis. The vehicle cab suspension radial damped bushing includes a nonelastomeric rigid inner plunger member having an inner member center bore with an inner member center axis with the inner member center axis offset from the outer member center axis, and includes a plurality of radial paddles extending radially outward towards the outer member. The radial damped bushing includes a first and second intermediate sidewall elastomer disposed between the inner member and the outer member and forming a cavity for constraining a viscous fluid around the radial paddles wherein a supported load applied to the inner member centers the inner member center axis with the outer member center axis and a motion of the inner member relative to the outer member paddles the viscous fluid in the toroidal cavity with the radial paddles.

Assignee:

Lord Corporation - Cary NC

International Classification:

F16D 376

US Classification:

464 89

Abstract:

A drive coupling is fail-safed by providing an inner metallic member with a pair of machined opposing flat surfaces that can engage a pair of pins that are positioned in pockets in the intermediate elastomeric member. These pins are anchored in place with respect to the outer housing by staking the ends of the pins, or the like.

International Classification:

F16D 364

US Classification:

464 82

Abstract:

A dual-rate drive coupling (20) for use in transmitting drive torque between drive and driven members. The first torque rate is near zero for no-load and near no-load conditions. A pair of flexible elastomeric arms (24, 26) which is preferably bonded to the inner member (22) are received in recessed portions (44, 46) in the outer member (40) and provide the coupling with this first very low torque rate. When higher torque loading produces a relative rotation between the outer member (40) and the inner member (22) of at least about 15. degree. , a pair of snubbing arms (28, 30) of the inner member (22) interact with surfaces of openings (48, 50) of the outer member (50). The contact surfaces of these second snubbing arms (28, 30) are coated with an elastomer to snub all contact between the inner member (22) and the outer member (40) to inhibit vibration induced rattling. In a second preferred embodiment, the elastomeric arms are curved in opposite directions and the metal arms are skewed away from drive engagement such that a relative rotation of at least about 25. degree. is needed to bring the second pair of arms (28, 30) into driving engagement with the outer member (40).
