In a method for actuating a starting device for an internal combustion engine, for the case in which the rotational speed of the toothed ring is below a limit value, first a stroke armature in a starter relay is moved and an electric starter motor is switched on after the starter pinion has engaged. If the rotational speed of the toothed ring exceeds the limit value, the starter motor is switched on before the starter pinion contacts the toothed ring.

Method for actuating a starting device for an internal combustion engine

The invention relates to a starter relay () for internal combustion engines, comprising a relay coil () and an armature (), which interacts with a fork lever () by way of a driver () so as to toe-in a starter pinion, and comprising a contact bridge () which is to be actuated by the armature by way of a switch axis () and interacts with switch contacts (), wherein a coupling () connects the switch axis and the armature such that they can be displaced with respect to each other to a limited extent. In order to ensure that welded contacts tear open and the neutral position of the fork lever is achieved when the relay is shut off, a pretensioned compression spring () is inserted between the armature () and the end of the fork lever ().

Starter relay of a starter device for internal combustion engines

A relay, in particular for a starter for an internal combustion engine for use in a motor vehicle. The relay has a self-resilient contact bridge, which for a reversible change in shape effected by the contact pressure, in particular widening, is embodied in curved form.

Relay with self-resilient contact bridge

A power supply system for starter devices has an energy storage unit, a starter device supplyable with electrical energy from the energy storage unit, a power supply line which carries the electrical energy from the energy storage unit to said starter device, a disconnection switch between the energy storage device and the starter device, the disconnection switch being located reversibly and directly on the energy storage unit.

Power supply system for a starter device with a reversible disconnection switch

A relay ( ), in particular for a starter for an internal combustion engine, is proposed. The relay ( ) includes a relay coil ( ) and a solenoid armature ( ) which can be moved when full battery current flows to the relay coil ( ). A contact member ( ) can be actuated by the solenoid armature ( ), whereby an operating lever ( ) is situated on the contact member ( ). It is provided that a coupling element ( ) connects the operating lever ( ) and the solenoid armature ( ) with each other in a manner that allows them to slide with limits.
