Abstract
Methods and systems are provided for a pulley insert. In one example, a pulley insert for a FEAD pulley comprises a first member insertable into a pulley such that the first member is rotatable within the pulley, the first member comprising a cavity for receipt of a second member; and a second member insertable into the cavity of the first member such that, when the first member is inserted into a pulley and the second member is inserted into the cavity of the first member, the second member prevents rotation of the first member relative to the pulley.
Claims18
An insert for a front end accessory drive (FEAD) pulley, comprising:
- a first member insertable into a pulley opening of the FEAD pulley, wherein the first member is rotatable within the pulley opening in a first direction, the first member comprising a cavity for receipt of a second member, wherein the second member blocks rotation of the first member within the pulley opening in a second direction opposite the first direction, wherein the first member comprises a first member limb, wherein the first member limb is a protrusion away from a first member body, wherein at least part of the FEAD pulley is located within the cavity when the first member is inserted into the FEAD pulley and the second member is inserted into the cavity of the first member.
A system, comprising:
- a vibration cover assembly comprising a first member and a second member, wherein the first member is configured to physically couple to a plurality of spokes of a pulley to block separation of the first member from the pulley, wherein the second member engages with the first member and the pulley to block rotation of the first member within a plurality of pulley openings of the pulley in a direction away from a locked position, wherein the first member comprises a plurality of first member limbs extending from a first member body, the plurality of first member limbs extend in a direction perpendicular to the first member body, and wherein a plurality of protrusions extend from each of the plurality of first member limbs, wherein the plurality of protrusions are spaced away from the first member body and extend in a circumferential direction, wherein at least part of the pulley is located within a cavity of the first member when the first member is inserted into the pulley and the second member is inserted into the cavity of the first member.
A method of inserting an insert into a FEAD pulley, comprising:
- inserting a plurality of protrusions and a plurality of first member limbs of a first member of the insert through a plurality of pulley openings arranged between adjacent spokes of a plurality of spokes a FEAD pulley;
- rotating the first member to a locked position, wherein the locked position comprises the plurality of protrusions are arranged against surfaces of the plurality of spokes facing away from the first member;
- and
- inserting a plurality of second member limbs of a second member of the insert through a plurality of recesses of the first member and through the plurality of pulley openings, wherein a plurality of clips of the second member physically couple to a plurality of clip receivers of the first member.
