Abstract

An accessory drive tensioner system may include a bracket, a coupling mechanism, and a biasing member. The bracket may have an aperture therethrough and a tensioner hub coupled thereto. The coupling mechanism may extend through the aperture to rotatably couple the bracket to a mounting member that is fixed relative to an engine. The biasing member may be engaged with the coupling mechanism and the bracket to bias the bracket axially along the coupling mechanism.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 60 / 921,798, filed April 4, 2007. The content of the above application is incorporated herein by reference. technical field [0003] The present disclosure relates to engine accessory drive systems, and more particularly, to accessory drive tensioner systems. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Electric hybrid vehicles include an internal combustion engine, an electric drive motor, and a rechargeable battery that provides power to the drive motor. The electric motor transmits power through engagement with the engine crankshaft and charges the battery. The engaging means may comprise a belt drive system. A belt drive system includes a belt that engages the crankshaft and the input / output of the motor to transmit r...
