Definitions

  • the invention relates to a starting device for an internal combustion engine in a motor vehicle with a starter motor and a starter relay, with the starting of the internal combustion engine, a starter motor driven starter pinion with a ring gear of the internal combustion engine is engageable and the starter motor and the starter relay for a start Stop operation separated from a starter control and defined are controllable.
  • the invention further relates to a method for operating a, in particular described above, starting device with a starter control for an internal combustion engine in a motor vehicle for performing a start-stop operation, wherein the starter pinion is accelerated by the starter motor to a defined speed, and Starter pinion is meshed in an outgoing rotating ring gear at a defined time with substantially synchronous speed.
  • the starting device is formed with a mechanical means for adjusting the rotational speed of the starter pinion to the speed of an outgoing sprocket.
  • the mechanical device thus provides an adjustment of the speed of the starter pinion and the speed of the expiring ring gear of the internal combustion engine without a highly accurate synchronization of the speeds must be performed by a complex electrical and electronic method.
  • a fundamental idea is, by the mechanical means, the speed of the starter pinion to a synchronous speed of rotation of the teeth to adapt to the sprocket.
  • a clutch similar to a centrifugal clutch provided to wear as possible to compensate for different speeds.
  • a friction disc is formed on the drive axle of the starter pinion as a mechanical means for adjusting the rotational speeds.
  • the friction disc is provided to form a clutch to the ring gear when the starter pinion is to be meshed in the start-stop operation at a rotating ring gear.
  • the friction disc has the advantage that it is a simple mechanical component that forms a low-wear coupling by frictional connection.
  • the ring gear is formed on the end face opposite the starter pinion with a radial, annular friction surface below the teeth to frictionally adjust the friction disk of the starting device to the speed.
  • the annular friction surface is specially treated or machined on the sprocket to perform a frictional connection between the mounted on the starter axle friction disc and the sprocket long-lasting and with recurring same quality.
  • This friction surface may, for example, in particular be heat treated or may be made particularly rough.
  • the friction disc is formed adjacent to a conical contact surface with the toothed rim.
  • the conical contact surface of the friction disc and the starter pinion is pressed to adjust the rotational speeds on a complementary conical counter surface of the ring gear, so that they give a solid coupling.
  • a conical surface has the advantage that the forces not only act axially, but also come to bear radially when compressing the friction disc and the ring gear.
  • the starter pinion with fishing hook on the front side, the sprocket opposite is formed.
  • the fishing hooks are made of spring steel.
  • the catch hooks further reduce tooth flank wear so that the starter pinion is meshed with the sprocket at substantially synchronous speed.
  • the catch hooks a synchronous speed is reached faster.
  • the fishing hooks have a long life, the fishing hooks are preferably made of spring steel.
  • the object is also achieved by a method in that a mechanical device is delivered against the sprocket to adjust the speeds of a high-speed starter pinion and a rotating, expiring sprocket in start-stop operation, the rotating expiring sprocket is touched by the mechanical device , the rotational speeds of the starter pinion and the ring gear are mechanically adjusted to a synchronous speed and the starter pinion is meshed after passing through the mechanical device in the ring gear. Due to this method according to the invention a Einspurvorgang is possible in a start-stop operation with expiring internal combustion engine, wherein the tooth flank wear is significantly reduced due to a precise synchronization of two gears.
  • the method is easy to implement and requires no high-precision and difficult control of the starter motor, the starter relay or the internal combustion engine. There are no sensor elements required. A complex electronics would possibly have to be supported by computer program products which advantageously eliminated.
  • the starter motor is thus accelerated in the start-stop operation when the engine is running out, and at a predetermined time at which an approximately equal speed of the ring gear has been determined, the starter pinion is meshed with the ring gear.
  • the mechanical device is compliant when meshing the starter pinion, designed as a mechanical friction plate is pressed by a spring, in particular a coil spring against the ring gear to adjust the speeds.
  • the spring has an initial contact with only a lower spring force, which is always greater when the starter pinion, so that the frictional force increases to the feed path of the starter pinion.
  • the rotational speed can thus be adapted better and better to the delivery or closing process of the clutch, so that it is essentially identical at the time the tooth flanks from the starter pinion and the ring gear meet.
  • the rotational speed of the ring gear and the rotational speed of the starter pinion are pre-synchronized with the friction disc and the friction disc is pressed against the ring gear for fine synchronization. Thereafter, the starter pinion is meshed into the ring gear.
  • the mechanical device is a fine synchronization that does not require expensive electronics, possibly with software, and is designed for the service life of the vehicle if the material is selected appropriately.
  • the Fig. 1 shows a schematic side view of a starting device according to the invention 1.
  • the starting device 1 has a not specifically illustrated starter relay to fulfillspuren in the ring gear 2 of an internal combustion engine, not shown, a starter pinion 3.
  • a friction disk 4 is arranged in a form-fitting manner on the front side, which lies opposite the ring gear 2, in the unstrapped state.
  • the friction disc 4 rotates with the starter pinion 3. Both are driven directly by a starter motor 5 on a starter axis.
  • the friction disc 4 is axially movable on the starter axis and is biased by a spring 6 which is preferably a coil spring.
  • the friction disc 4 forms a mechanical device to adjust two speeds in start-stop operation.
  • the ring gear 2 rotates with an expiring speed due to an expiring, switched-off internal combustion engine and the starter motor 5 accelerates the starter pinion 3 with an increasing speed, so that both speeds are finally synchronized by designed as a mechanical device friction disk 4.
  • the speeds can be adjusted before the meshing of the starter pinion 3 by simple electrical and electronic methods, so that by means of the mechanical device only a fine adjustment is carried out so that a mechanical wear is reduced to a minimum.
  • the Fig. 1 shows a state of the starting device 1, in which the friction disc 4, the sprocket 2 is not touched.
  • the Fig. 2 shows a particular embodiment in a temporally advanced state of Einspurvorgang in start-stop operation.
  • the friction disc 4 which touches the starter pinion 3 facing end face 24 of the ring gear 2, increasingly pressed in time to a radial annular friction surface 25 to compensate for a speed difference from the starter pinion 3 and the ring gear 2.
  • the starter pinion 3 passes through the friction disc 4, as in the Fig. 3 is shown, so that the teeth of the starter pinion 3 engage the teeth of the ring gear 2, wherein the peripheral speeds of the two gears are substantially identical.
  • the ring gear 2 runs out together with the meshed starter pinion 3 and the internal combustion engine can be started at any time in start-stop operation due to the starter pinion meshed in 3. Minimum times no longer have to wait.
  • the two speeds of the starter pinion 3 and the ring gear 2 can thus be synchronized in a self-adjusting process without complex control.
  • the Figure 4 shows a further schematic side view of the inventive device for carrying out the Einspurvons invention.
  • the ring gear 2 is formed with a cylindrical collar 20, so that the friction disc 4 also radially, and not only axially, as in the in Fig. 1 to 3 shown embodiments is pressed against the ring gear 2.
  • This has mechanical advantages that possibly occurring slip is avoided.
  • such an arrangement also has the disadvantage that a systematic speed error can occur because the circumference of the cylindrical collar 20 is smaller than that of the tooth flanks of the ring gear 2, so that here a slight speed difference occurs, but which is significantly smaller than the speed difference to be compensated between the starter pinion 3 and the ring gear 2.
  • the speed difference is taken into account in the selection of materials accordingly.
  • the Fig. 5 shows a further modification of the embodiments of Fig. 1 to 4 ,
  • the contact surface 23 of the friction disc 4 and the complementary mating surface 22 on the ring gear 2 is conical.
  • a conical design has the advantage that both radial and axial forces act and thus a good Reibhaftkraft can be achieved.
  • the speed differences can be better compensated by a corresponding conical contact, since the contacting contact surface is increased compared to only a radial or axial contact.
  • the Fig. 6 shows a time-speed-distance diagram.
  • the speed n B of the internal combustion engine during a start-stop operation is shown.
  • the internal combustion engine is lowered to an idling speed n 0 at a time t 0 .
  • a start-stop operation is caused by the engine control, so that the internal combustion engine is turned off.
  • the starter motor 5 is accelerated by a starter control, which controls the starter motor 5 and the starter relay separately.
  • the mean time-speed diagram of the Fig. 6 shows the speed at n S from the starter motor. Below in the bottom diagram of the path s 3 is shown by the starter pinion 3.
  • the starter pinion 3 is delivered together with the friction disc 4 by means of the starter relay on the sprocket 2.
  • the friction disc 4 touches the ring gear 2, so that a synchronization of the speed of the expiring sprocket 2 takes place at the speed of the expiring starter motor 5.
  • time t 4 is an identical speed before and a gap to tooth position between starter pinion 3 and sprocket 2, so that from the time t 4, the starter pinion 3 is meshed for positive engagement until the time t 5 .
  • both the coarse synchronization and a fine synchronization are performed by the friction disc 4 as a mechanical device.
  • a synchronization of the rotational speeds by means of an electronic control of the starting device is made in a rough speed range and the approximate Einspurzeittician determined so that the friction plate 4 is used for a fine synchronization.
  • the Fig. 7 shows an end view of a starter pinion 3 and the friction disc 4 in a simplified representation.
  • the front view shows how the starter pinion 3 can positively pass through the friction plate 4 and is positively slidable on a driven starter axle 35.
  • the Fig. 8 schematically shows a particular embodiment of the friction disc with catch hooks 32 arranged in the end face 30 of the starter pinion 3 in order to prevent tooth flank wear even better.
  • the fishing hooks 32 are made of particularly durable materials, such as spring steel. The fishing hooks 32 thus serve the fine synchronization between the starter pinion gear 3 and sprocket 2. All figures show only schematic representation not to scale. In addition, reference is made in particular to the drawings for the invention as essential.
