Engagement relay for and method for operating a preferably designed as a starting device electrical machine with an engagement relay

摘要

The invention relates to an engagement relay (20) for an electrical machine, which preferably serves as a starting device (10) for engaging a pinion (25), wherein the engagement relay (20) has a contact device (65) for electrically connecting electrical contacts (120, 121). comprising, with a switching axis (67) to be actuated for electrical connection, with a thrust motor (60), which serves to displace the switching axis (67), and the thrust motor (60) has a movable part (57), which is the switching axis (67) to operate, wherein the movable part (57) is connected to a driver (85), wherein a stop member (84) relative to the movable part (57) of the thrust motor (60) is movable and in a resting state of Engagement relay '(20) between the stop member (84) and the driver (85) is a gap (s), wherein after switching on the engagement relay (20) actuates a contact device (65) and thereby a switch of the circuit of the Starterm otors (23) is closed, wherein a movable part (57) of a thrust motor (60) of the engagement relay '(20) with a driver (85) is connected and by a switch-on movement of the movable part (57) of the driver (85) on a Engagement lever (22) causes an engagement force to einzuspuren a pinion (25) in a sprocket (15), characterized in that between the movable part (57) of the thrust motor (60) and the driver (85) a stop member (84) is, wherein first between the driver (85) and the stopper member (84) has a gap (s) is present with an initial size and when moving the movable part (57) of the thrust motor (60) when switching the gap (s) is reduced.
