The insulating device comprises: a first annular part, which is adapted to be in contact to the outer circumferential surface of the outer ring, and a second annular part, which is also adapted to be in contact to the outer circumferential surface of the outer ring. The first and second part form the insulation device which is adapted to contact, in an assembled state of the bearing in the housing, both the outer ring and the housing. The first part is thermally conductive and electrically insulating and the second part is electrically insulating and less thermally conductive than the first part or is not thermally conductive.

    Abstract: A two-mode rocker clutch, including: a clutch gear; a housing; a first pawl including an end and a portion disposed within the housing; an actuation assembly; a second pawl including a portion disposed within the housing; and a resilient element urging the second pawl into contact with the clutch gear. For a one-way mode, the clutch gear is rotatable, with respect to the housing, only in a first circumferential direction. To transition from the one-way mode to a locked mode: the second pawl blocks rotation of the clutch gear, with respect to the housing, in a second circumferential direction, opposite the first circumferential direction; the actuation assembly is arranged to pivot the first pawl into contact with the clutch gear; and the end of the first pawl is arranged to block rotation of the clutch gear, with respect to the housing, in the first circumferential direction.
