Abstract
A series type decoupler joint includes a driving pulley, a driven pulley and a flexible rubber core coupled therebetween. The driving pulley has an inner hub for mounting onto a shaft and an outer rim for engaging a driving belt. The driven pulley has an inner hub having a bearing assembly for rotatably mounting the inner hub onto the shaft and an outer rim for engaging a driven belt. The flexible rubber core is bonded between the driving pulley and the driven pulley.
Claims32
A series type decoupler joint comprising
- a driving pulley,
- a driven pulley,
- a sleeve for mounting said decoupler joint on a shaft, said driving pulley and said driven pulley mounted on said sleeve with said driving pulley engaging said sleeve for rotation therewith and said driven pulley rotatably engaging said sleeve, and
- a flexible rubber core extending between said driving pulley and said driven pulley for elastically coupling said driving pulley to said driven pulley.
A series type decoupler joint comprising:
- a driving pulley having an inner hub for mounting onto a shaft and an outer rim for engaging a driving belt,
- a driven pulley having an inner hub having means for rotatably mounting said inner hub onto the shaft and an outer rim for engaging a driven belt, and
- a flexible rubber core extending between said outer rim of said driving pulley and said inner hub of said driven pulley, wherein said driving pulley and said driven pulley are in a side-by-side relation.
A series type decoupler joint comprising
- a driving pulley having an inner hub for mounting said decoupler joint on a shaft, and
- a driven pulley rotatably mounted on said inner hub, said driving pulley being nested within said driven pulley, and
- a flexible rubber core extending radially between said inner hub of said driving pulley and an outer rim of said driven pulley for elastically coupling said driving pulley to said driven pulley.
An engine for a motor vehicle comprising:
- a rotatable drive shaft having an associated pulley assembly mounted thereon;
- a plurality of rotatable driven shafts for driving various components for the motor vehicle including an alternator, each of said driven shafts having an associated pulley assembly mounted thereon;
- at least a designated one of said shafts having said associated pulley assembly mounted thereon constituting a decoupler joint, said decoupler joint comprising separate first and second pulley members carried by a mounting sleeve, said first and second pulley members being rotatably coupled to one another by a resilient member,
- said first pulley member fixedly mounted with respect to said designated shaft, and said second pulley member being mounted for instantaneous rotational movement relative to said designated shaft, said rotational movement being limited by said resilient member coupled between said first and second pulley members,
- a first endless flexible belt trained about a first set of pulley assemblies, including the pulley assembly mounted on said drive shaft,
- a second endless flexible belt trained about a second set of pulley assemblies, including the pulley assembly mounted on the driven shaft for the alternator, and
- said first endless flexible belt being trained about said first pulley member, and said second endless flexible belt trained about said second pulley member.
