The invention relates to an engagement relays () for an electric machine which preferably serves as a starter device () for engaging a pinion, wherein the engagement relay () has a contact device () for electrically connecting electrical contacts () having a switching axis () which can be actuated for the purpose of electrical connection, having a thrust motor () which serves to shift the switching axis () and the thrust motor () has a movable part () which serves to activate the switching axis (), wherein the movable part () is connected to a driver (), wherein a stop part () can move relative to the movable part () of the thrust motor () in a state of rest of the engagement relay () there is a gap(s) between the stop part () and the driver (), wherein after the switching of the engagement relay () a contact device () is activated and as a result a switch of the circuit of the starter motor () is closed, wherein a movable part () of a thrust motor () of the engagement relay () I connected to a driver () and by means of a switch-on-movement of the movable part () the driver () brings about an engagement force with an engagement lever (), in order to mesh a pinion () in a toothed ring (), characterized in that a stop part () is arranged between the movable part () of the thrust motor () and the driver (), wherein firstly there is a gap(s) with an initial size between the driver () and the stop part () and when the movable part () of the thrust motor () moves during switching the gap(s) is made smaller.

Engagement relay for and a method for operating an electric machine, preferably embodied as a starter device, with an engagement relay

An electric machine for starting an internal combustion engine, comprising a housing () having at least one sealing device () which seals an interior () of the housing with respect to the surroundings of the housing (), and at least one pressure reduction device (), wherein the at least one pressure reduction device () is embodied so as to be moveable in a translatory fashion relative to the at least one sealing device () in order to form, in the case of an overpressure in the interior () of the housing, at least one venting duct via which an at least partial reduction in pressure is ensured.

Electric machine and method for operating an electric machine

The invention relates to a switching relay (), particularly for a starting device for starting an internal combustion engine, having a contact device (), a relay coil (), an armature (), and an actuating rod (), wherein the actuating rod () is displaced by the armature () when current is applied to the relay coil () and the contact device () is actuated by the actuating rod (), and having a contact ripping device by means of which the armature () and the actuating rod () are coupled to each other. In order to simplify assembly and disassembly, the contact ripping device is implemented having a latching device in the armature ().

Switching relay having contact ripping device

The invention relates to a starter () for an internal combustion engine, comprising a starter motor () which can be coupled to the internal combustion engine by means of a pinion (), and a device for engaging the pinion () in a gear rim () of the internal combustion engine and connecting the starter motor () to a DC voltage supply system (). In order to disconnect the sequence of operations, the device has separate means, in particular separate relays (), for engaging the pinion () on one hand and turning on the starter motor on the other when the internal combustion engine is started, thus preventing reactions of the engagement dynamics on the contact system when the motor current is switched.

Starter for an internal combustion engine

A starter device for cranking internal combustion engines, that has a terminal for starter control, having an electric starter motor, there being an electric supply line from a plus terminal of the starter device to the plus terminal of the starter motor, and the starter motor having an electrical ground return line at a minus terminal of the starter device, in which the ground return line is interrupted by a switch in the case of an electrical potential-free terminal for the starter control.

Starter device

A starter for an internal combustion engine, particularly for an internal combustion engine of a motor vehicle, having a housing, on which a mounting flange is developed that can be associated with the internal combustion engine, at least one insulating part being associated with the mounting flange, such that no electrical connection exists between the starter and the internal combustion engine. An internal combustion engine, particularly for a motor vehicle, has a starter as described above. A retaining flange for an electric motor, particularly for a starter of a motor vehicle, the retaining flange being developed as an insulating part, and is made up at least partially of an electrically insulating material and/or has at least one electrically insulating insulating element situated on the retaining flange.
