Abstract

A tensioner assembly that includes a base, an arm, an opening spring (i.e., a torsion spring that opens or radially expands with increasing torque applied thereto), a spring reaction member, and a pivot bushing. The tensioner assembly is configured to orient various loads in predetermined directions. For example, a spring load can be oriented to counteract a hub load to reduce a bushing load that acts on the pivot bushing. As another example, a spring reaction force exerted by the spring reaction member can be employed by a damping mechanism to generate a grounding force that is parallel to the spring reaction force and is directed to intersect an axis about which the arm pivots relative to the base. A tensioner assembly having improved assembly characteristics is also provided.
