The invention relates to an engagement relays (20) for an electric machine which preferably serves as a starter device (10) for engaging a pinion, wherein the engagement relay (20) has a contact device (65) for electrically connecting electrical contacts (120, 121) having a switching axis (67) which can be actuated for the purpose of electrical connection, having a thrust motor (60) which serves to shift the switching axis (67) and the thrust motor (60) has a movable part (57) which serves to activate the switching axis (67), wherein the movable part (57) is connected to a driver (85), wherein a stop part (84) can move relative to the movable part (57) of the thrust motor (60) in a state of rest of the engagement relay (20) there is a gap(s) between the stop part (84) and the driver (85), wherein after the switching of the engagement relay (20) a contact device (65) is activated and as a result a switch of the circuit of the starter motor (23) is closed, wherein a movable part (57) of a thrust motor (60) of the engagement relay (20) I connected to a driver (85) and by means of a switch-on-movement of the movable part (57) the driver (85) brings about an engagement force with an engagement lever (22), in order to mesh a pinion (25) in a toothed ring (15), characterized in that a stop part (84) is arranged between the movable part (57) of the thrust motor (60) and the driver (85), wherein firstly there is a gap(s) with an initial size between the driver (85) and the stop part (84) and when the movable part (57) of the thrust motor (60) moves during switching the gap(s) is made smaller.
Engagement relay (20) for an electric machine, which preferably serves as a starter device (10) for engaging a pinion (25), with the engagement relay (20) comprising a contact device (65) for the electrical connection of electrical contacts (120, 121), with a switching axis (67) which must be actuated for the electrical connection, with a thrust motor (60), which serves to displace the switching axis (67) and with the thrust motor (60) comprising a movable part (57), which serves to actuate the switching axis (67), the movable part (57) being connected with a driver (85), characterized in that a stop part (84) is movable relative to the movable part (57) of the thrust motor (60) and has a gap (s) between the stop part (84) and the driver (85) when the engagement relay (20) is in a state of rest.
Method for operating an electric machine formed in particular as a starter device (10) with an electric starter motor (23) and with an engagement relay (20) wherein, after the engagement relay (20) has been turned on, a contact device (65) is to be actuated which closes a switch of the circuit of the starter motor (23) to be closed, wherein a movable part (57) of a thrust motor (60) of the engagement relay (20) is connected with a driver (85), and causes through an actuating motion of the movable part (57) of the driver (85) on an engagement lever (22) an engagement force to engage a pinion (25) in a toothed ring (15), wherein a stop part (84) is arranged between the movable part (57) of the thrust motor (60) and the driver (85), with a gap (s) with a starting size being initially present between the driver (85) and the stop part (84), with the gap (s) decreasing as the movable part (57) of the thrust motor (60) is moved during switching.
