Abstract: 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.

Abstract: The invention relates to a starting method for internal combustion engines in motor vehicles, comprising a start-stop system, and to a starting device (10) for carrying out said method, said starting device comprising a starter motor (11) and an insertion device (12, 20) which axially inserts a slip-on pinion (13) into a crown gear (14) of the internal combustion engine when a stop cycle begins. In order to minimize the period until the engine can be restarted, the pinion (13) is resiliently inserted into the still rotating crown gear (14) by means of a pressure spring (25) when the stop phase begins, once the internal combustion engine (15) is switched off but before it comes to a standstill and with the starter motor (11) switched off.

Abstract: The invention relates to an electric machine, in particular a commutator machine (10), the carbon brushes (14) of which cooperate with a commutator (13) to supply the rotor with current, the carbon brushes (14) 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 (14), a maximum of half, preferably less than half of all the carbon brushes (14) of the machine have a significant fraction of an additive, said fraction differing from that of the other carbon brushes (14).

Abstract: 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 ?, which deviates from 180°.

Abstract: 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 ?3/2.

Abstract: A carbon brush system for an electrical machine, having at least two carbon brushes, which are situated axially adjacent to one another and cooperate with a rotatable countercontact system. The carbon brushes are implemented as directly or indirectly mutually axially supporting carbon brushes.

Abstract: 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.

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.

Abstract: The invention relates to a starter device (10) for internal combustion engines (15) in motor vehicles with a controller (19), a starter relay (12), a starter pinion (13) and a starter motor (11), whereby on each start/stop process in the stop phase (first step) the starter relay engages the starter pinion in the toothed ring (14) of the engine and in the start phase (second step) the engine is turned over by the starter motor. According to the invention, the starter pinion (13) may be engaged as quietly as possible for a subsequent starting process on switching off the engine (10) and held in position until starting, whereby, in the first step of the starting process, the armature (28) of the starter relay (12) is withdrawn with reduced force to a position with open switch contact (18) and held there until the start of the second step, whereupon the armature (28) closes the switch contact (18) of the starter motor with full force.

Abstract: 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 (47) of an internal combustion engine. With this starter, a pushing-forward of the driven shaft (33) to engage a pinion (45) in the flywheel ring gear (47) is brought about by means of a pole tube (9) located on the stator (5) of the starter motor (5, 7), which said pole tube executes a turning motion around the motor axis when the starter motor (5, 7) is energized. Means (55, 63, 77, 79) are provided that convert the turning motion of the pole tube (9) directly into an axial motion acting on the driven shaft (33).

Abstract: A starter device for starting internal combustion engines having a starter motor (20) that comprises a stator (22) and a rotor (23) as well as a drive shaft (58) as starter components (21), further having a driven element (70) that can actively be connected to the drive shaft (58) and the internal combustion engine, and having a brake device (100) that acts on the driven element (70) is proposed. The starter device is characterized in that the brake device (100) can be actuated by means of at least one starter component (21) by switching on the starter motor (20).
