Abstract
Official abstract text for this publication.
A tensioning system including a magnetic stop is provided. The tensioning system includes a tensioner arm and a support. The tensioner arm is mounted on the support for pivoting movement. The support includes a support magnetic or ferromagnetic element on at least a first surface thereof. The tensioner arm includes a tensioner arm magnet on at least a second surface thereof that faces the first surface of the support.
First claim
Opening claim text (preview).
What is claimed is: 1. A tensioning system, comprising: a tensioner arm and a support, the tensioner arm being mounted on the support for pivoting movement, the support including a support magnetic or ferromagnetic element on at least a first surface thereof, the tensioner arm including a tensioner arm magnet on at least a second surface thereof that faces the first surface of the support, and (1) the support magnetic or ferromagnetic element and (2) the tensioner arm magnet magnetically interact with each other to adjust a position of the tensioner arm relative to the support. 2. The tensioning system of claim 1 , wherein the support magnetic or ferromagnetic element is a support magnet having a first polar orientation that is arranged relative to a polar orientation of the tensioner arm magnet such that the support magnet and the tensioner arm magnet are attracted to one another. 3. The tensioning system of claim 1 , wherein the support magnetic or ferromagnetic element is a support magnet having a first polar orientation that is arranged relative to a polar orientation of the tensioner arm magnet such that the support magnet and the tensioner arm magnet repel one another. 4. The tensioning system of claim 1 , wherein a gap defined between the support magnetic or ferromagnetic element and the tensioner arm magnet is 0.4 mm-0.6 mm. 5. The tensioning system of claim 1 , wherein a gap defined between the support magnetic or ferromagnetic element and the tensioner arm magnet is 0.5 mm. 6. A tensioning system, comprising: a tensioner arm and a support, the tensioner arm being mounted on the support for pivoting movement, the support including a support magnetic or ferromagnetic element on at least a first surface thereof, and the tensioner arm including a tensioner arm magnet on at least a second surface thereof that faces the first surface of the support, wherein the tensioner arm further includes a mounting region at a pivot end where the tensioner arm is mounted to the support and about which the tensioner arm pivots, an actuation region configured to engage an actuator that adjusts a position of the tensioner arm, and a pulley support region configured to support a pulley on which a belt or chain is guided, and the tensioner arm magnet is arranged at a distal end of the tensioner arm from the pivot end. 7. The tensioning system of claim 1 , wherein the tensioner arm magnet is fixed to the tensioner arm by fasteners. 8. The tensioning system of claim 1 , wherein the tensioner arm is formed from aluminum. 9. The tensioning system of claim 1 , wherein the support magnetic or ferromagnetic element is arranged on an axial end face of the support, and the tensioner arm magnet is arranged on an axial end face of the tensioner arm. 10. The tensioning system of claim 1 , wherein the support magnetic or ferromagnetic element and the tensioner arm magnet overlap in an axial direction. 11. The tensioning system of claim 1 , wherein the support magnetic or ferromagnetic element and the tensioner arm magnet form a magnetic stop.
