The invention relates to a starting method for internal combustion engines in motor vehicles, comprising a start-stop system, and to a starting device () for carrying out said method, said starting device comprising a starter motor () and an insertion device () which axially inserts a slip-on pinion () into a crown gear () of the internal combustion engine when a stop cycle begins. In order to minimize the period until the engine can be restarted, the pinion () is resiliently inserted into the still rotating crown gear () by means of a pressure spring () when the stop phase begins, once the internal combustion engine () is switched off but before it comes to a standstill and with the starter motor () switched off.

Method and device for start-stop systems of internal combustion engines in motor vehicles

A method is described for engaging a starting pinion of a starting device with a ring gear of an internal combustion engine, the starting pinion having a peripheral speed and the ring gear having a peripheral speed, the starting pinion being pushed forward axially along its axis of rotation, the starting pinion making contact with the ring gear at a peripheral speed which is lower than the peripheral speed of the ring gear.

The invention relates to an electric machine, in particular a commutator machine (), the carbon brushes () of which cooperate with a commutator () to supply the rotor with current, the carbon brushes () being continuously provided or provided in layer sections with different additives such as scouring material, lubricants or similar. To achieve a longer service life for the carbon brushes (), a maximum of half, preferably less than half of all the carbon brushes () of the machine have a significant fraction of an additive, said fraction differing from that of the other carbon brushes ().

Electric machine, in particular commutator machine

A circuit configuration for an electric machine, e.g., a starter motor for starting an internal combustion engine in a motor vehicle, includes a current limiting device for limiting a starting current of the electric machine. The circuit configuration includes a bridging device for bridging the current limiting device.

Circuit configuration for a starting device

A switching device has an electromagnetic switching element and a controller, the switching element including two coils on one core which act on a shared armature. In order to implement an operation of the armature to be activatable as rapidly and simply as possible with low power consumption, the controller is designed to have a switch in the current path of the coil in each case to activate each coil.

Switching device, starting device, and method for an electromagnetic switching device

An electrical component having a primary winding, a first field-effect transistor, configured as a switch of the primary winding, for switching the primary winding, a quench winding for quenching the inductive load of the primary winding when switching off the primary winding, and a second field-effect transistor, configured as a switch of the quench winding, for switching the quench winding. In the process, the first field-effect transistor is operated in linear operation and the second field-effect transistor is operated in linear operation or in a clock-pulsed operation between the linear operation and a switched-off state during a switching-off process of the quench winding.

Method and control unit for controlling an electrical component

An electrical component having a core and a first and second coil positioned around the core is controlled in such a manner, that in response to the second coil being switched off, the first coil is short-circuited via a quenching circuit to quench the inductive load of the second coil.

Electrical component and method for controlling an electrical component

An electric drive machine having a stator and a rotor, the rotor carrying a rotor winding, in slots, which is able to be supplied with electric current by a power supply system made up of a commutator and sliding contacts, the sliding contacts pressing on the surface of the commutator having at least two pairs each made up of one positive sliding contact and one negative sliding contact, and in the case of at least one first pair of a positive sliding contact and a negative sliding contact, the positive sliding contact and the negative sliding contact being opposed at an angle &#x3b3;, which deviates from 180&#xb0;.

A multilayer brush, which essentially contains a composite having a graphite component and having a copper component, and a layered structure, a first layer being furnished with a high copper component and a further layer being furnished with a comparatively low copper component. It is provided that the copper component of the first layer in comparison with the copper component of the second layer corresponds to a ratio of &#x2266;3/2.

A diagnostic device for the starter of a combustion engine is provided. The electrical system of a motor vehicle includes a battery in whose connecting line a battery disconnect switch is provided, and the electrical system of the motor vehicle is monitored by a vehicle electrical system state detection device which includes starter diagnostic functionality.

Motor vehicle energy management having a supplementary starter diagnostic function

A device for starting an internal combustion engine of a motor vehicle includes a starter motor having an actuator for engaging a pinion, drivable by the starter motor, with a ring gear, and a control unit which activates a switching output stage associated with the actuator and a switching output stage associated with the starter motor. The starting time of the internal combustion engine is substantially reduced by providing the starter device with a control unit.

Starter device for an internal combustion engine having separate engaging process and starting process

An inertia-drive starter is proposed, in the case of which a relay is not required to engage the pinion in the flywheel ring gear () of an internal combustion engine. With this starter, a pushing-forward of the driven shaft () to engage a pinion () in the flywheel ring gear () is brought about by means of a pole tube () located on the stator () of the starter motor (), which said pole tube executes a turning motion around the motor axis when the starter motor () is energized. Means () are provided that convert the turning motion of the pole tube () directly into an axial motion acting on the driven shaft ().
