Compliant Gear Assembly, Engine And Gear Train Operating Method

摘要

A compliant gear assembly for a gear train of an internal combustion engine includes a hub subassembly having a first hub component and a second hub component. The first hub component defines a first axis, and the compliant gear assembly includes a gear ring rotatable relative to the hub subassembly and defining a gear ring axis of rotation. The second hub component is movable relative to the first hub component between a first stop position and a second stop position. A compliance mechanism is coupled between the first hub component and the second hub component and biases the second hub component toward the first stop position. Translating the second hub component relative to the first hub component in a direction normal to the first axis attenuates torque spikes induced for example via fuel injector actuation and/or cylinder firing in an engine gear train employing the compliant gear assembly.
