Definitions

  • a starting device known which is designed as a so-called freely ejecting starter.
  • Freely ejected means that the pinion, which is intended to be meshed in the ring gear of an internal combustion engine, only at one end or only on one axial side of the pinion is stored (flying storage).
  • a starter pinion is shown, which is mounted on a drive shaft such that a torque can be transmitted between the drive shaft and starter pinion.
  • the starter pinion on the drive shaft is axially displaceable between two defined end positions.
  • the Andrehritzel is slightly sprung in the context of this displacement, so that not the whole inertia of the freewheel, the drive shaft and the pinion on the sprocket acts when striking the Andrehritzels the sprocket, but to a significantly reduced extent effectively only part of it.
  • the starting pinion appears to the skilled person in the embodiment disclosed here by means of a snap ring (snap ring) secured, which is secured by a sleeve-like, the snap ring on its outer side engaging portion against expansion under centrifugal load.
  • the disadvantage of this solution is that it requires an unnecessarily long drive shaft. This leads to unnecessarily high masses and thus to higher impact forces on the ring gear, as absolutely necessary.
  • a starting device with a drive end plate, in which a bearing is mounted, with a drive shaft, wherein the bearing in the bearing plate, the drive shaft is supported at least indirectly, with a starter pinion, which is mounted on the drive shaft such that from the drive shaft to the starter pinion a torque is transferable, wherein the starting pinion has an end face and a locking ring is arranged stationary on the drive shaft.
  • a stop ring engages over the retaining ring by means of an integrally molded collar. The collar of the stop ring is plastically deformed. This has the advantage that it is not a hardened stop ring is used, as has been the case, but a component which allows plastic deformation. Although hardened stop rings allow the absorption of high loads, but are very expensive.
  • the collar has at least one plastic deformation on its circumference.
  • the plastic deformation has an undercut between a seat portion of the stop ring and, which substantially prevents axial displacement of the stop ring.
  • the circlip is a snap ring.
  • a starter 10 is shown.
  • This starting device 10 has, for example, a starter motor 13 and an engagement relay 16.
  • the starter motor 13 and the engagement relay 16 are attached to a common drive bearing plate 19.
  • the starter motor 13 is functionally to drive a starter pinion 22 when it is meshed in the ring gear 25 of the internal combustion engine, not shown here.
  • the starter motor 13 has a housing as a pole tube 28 which carries on its inner circumference pole pieces 31, which are each wrapped by a field winding 34 (electrical exciter system). Instead of such an electrical exciter system, a permanent magnet can also be used.
  • a field winding 34 electrical exciter system
  • the pole shoes 31 in turn surround an armature 37, which has an armature packet 43 constructed from fins 40 and an armature winding 49 arranged in grooves 46.
  • the armature package 43 is pressed onto a drive shaft 44.
  • a commutator 52 is further attached, the u. a. composed of individual commutator fins 55.
  • the commutator bars 55 are so electrically connected in a known manner with the armature winding 49, that upon energization of the commutator fins 55 by carbon brushes 58, a rotational movement of the armature 37 in the pole tube 28 results.
  • a arranged between the Einspurrelais 16 and the starter motor 13 power supply 61 supplies in the ON state both the carbon brushes 58 and the field winding 34 with power.
  • the drive shaft 44 is commutator side supported with a shaft journal 64 in a sliding bearing 67, which in turn is held stationary in a commutator bearing cover 70.
  • the commutator cover 70 in turn is fastened by means of tie rods 73, which are distributed over the circumference of the pole tube 28 (screws, for example, two, three or four pieces) in the drive end plate 19. It supports the pole tube 28 on the drive bearing plate 19, and the commutator bearing cover 70 on the pole tube 28.
  • a so-called sun gear 80 connects to the armature 37, which is part of a planetary gear 83.
  • the sun gear 80 is surrounded by a plurality of planet wheels 86, usually three planet wheels 86, which are supported by means of roller bearings 89 on journals 92.
  • the planet gears 86 roll in a ring gear 95, which is mounted outside in the pole tube 28.
  • the planet wheels 86 are adjoined by a planetary carrier 98, in which the axle journals 92 are accommodated.
  • the planet carrier 98 is in turn stored in an intermediate storage 101 and a slide bearing 104 arranged therein.
  • the intermediate bearing 101 is designed cup-shaped, that in this both the planet carrier 98, and the planet wheels 86 are added.
  • the ring gear 95 is arranged in the cup-shaped intermediate bearing 101, which is ultimately closed by a cover 107 relative to the armature 37.
  • the intermediate bearing 101 is supported with its outer circumference on the inside of the pole tube 28.
  • the armature 37 has on the end facing away from the commutator 52 end of the drive shaft 44 has a further shaft journal 110, which is also received in a sliding bearing 113, from.
  • the sliding bearing 113 in turn is received in a central bore of the planet carrier 98.
  • the planetary carrier 98 is integrally connected to the output shaft 116.
  • This output shaft 116 is supported with its end 119 facing away from the intermediate bearing 101 in a further bearing 122 which is fixed in the drive bearing plate 19.
  • the bearing 122 supports the drive shaft 44 indirectly via the output shaft 116th
  • the output shaft 116 is divided into different sections.
  • the section which is arranged in the sliding bearing 104 of the intermediate bearing 101 a portion with a so-called spur toothing 125 (internal teeth), which is part of a so-called shaft-hub connection.
  • This shaft-hub connection 128 in this case allows the axially rectilinear sliding of a driver 131.
  • This driver 131 is a sleeve-like extension which is integral with a cup-shaped outer ring 132 of the freewheel 137.
  • This freewheel 137 (Richtgesperre) further consists of the inner ring 140 which is disposed radially within the outer ring 132. Between the inner ring 140 and the outer ring 132 clamping body 138 are arranged.
  • clamp bodies 138 in cooperation with the inner and outer rings, prevent relative rotation between the outer ring and the inner ring in a second direction.
  • the freewheel 137 allows a relative movement between inner ring 140 and outer ring 132 in one direction only.
  • the inner ring 140 at its end facing away from the freewheel 137 end a shaft-hub connection 141, for example.
  • the push-in relay 16 has a bolt 150, which is an electrical contact and which is connected to the positive pole of an electric starter battery, which is not shown here.
  • This bolt 150 is passed through a relay cover 153.
  • This relay cover 153 terminates a relay housing 156, which is fastened by means of a plurality of fastening elements 159 (screws) on the drive end plate 19.
  • a pull-in winding 162 and a so-called holding winding 165 is further arranged.
  • the pull-in winding 162 and the holding winding 165 each cause an electromagnetic field in the switched-on state, which flows through both the relay housing 156 (made of electromagnetically conductive material), a linearly movable armature 168 and an armature return 171.
  • the armature 168 carries a push rod 174, which is moved in the direction of linear retraction of the armature 168 in the direction of a switching pin 177. With this movement of the push rod 174 to the switching pin 177 this is moved from its rest position in the direction of two contacts 180 and 181, so that attached to the contacts 180 and 181 end of the switching pin 177 contact bridge 184 connects both contacts 180 and 181 electrically. As a result, electrical power is conducted from the bolt 150 across the contact bridge 184 to the power supply 61 and thus to the carbon brushes 58.
  • the starter motor 13 is energized.
  • the engagement relay 16 or the armature 168 also has the task, with a tension member 187 to move the drive bearing plate 19 rotatably arranged lever.
  • This lever 190 usually designed as a fork lever, surrounds with two "tines" not shown here on its outer circumference two discs 193 and 194 to move a trapped between these driver ring 197 for freewheel 137 towards the resistance of the spring 200 and thereby the starter pinion 22 technicallyspuren in the ring gear 25.
  • FIG. 2 shows a partial longitudinal section of a freely ejecting starter.
  • This has a bearing plate 19, in which a bearing 122 is used, which is designed for example as a roller bearing possibly in a special form as a needle bearing. However, this can also be designed as a sliding bearing or as a ball bearing.
  • the starter pinion 22 In both embodiments according to FIG. 1 and FIG. 2 sits on the drive shaft 142, the starter pinion 22.
  • the drive shaft 142 on its outer circumference on a shaft-hub connection 141, which allows the transmission of torque from the inner ring 140 to the starter pinion 22.
  • the starter pinion 22 has a bore which has a wedge or serration on its inner circumference, and which engages in a corresponding counterpart on the drive shaft 142.
  • the portion of the shaft-hub connection on the drive shaft is at 143, and the portion of the shaft-hub connection in the pinion is designated 144.
  • the starter pinion 22 is supported on an end face 145 which is directed in the direction of the freewheel 137, by means of a spring element 146, here in the form of a disk disk, on a non-descript collar of the drive shaft 142 from.
  • FIG. 2 The starter pinion 22 has a further end face 203, which is arranged on the other axial side of the Andrehritzels 22 and is accordingly remote from the freewheel 137.
  • a recess 206 is introduced, according to FIG. 2 is designed as a hollow cylinder.
  • This recess 206 engages over a locking ring 209, which is designed here as a snap ring.
  • This circlip 209 is seated in a circumferential groove 212, which is introduced in the circumferential direction in the drive shaft 142.
  • a stop ring 218 is further introduced, which engages over the retaining ring 209 by means of an integrally molded collar 220.
  • a starting device 10 is provided with a drive bearing plate 19, in which a bearing 122 is fixed, with a drive shaft 142, wherein the bearing 122 in the bearing plate 19, the drive shaft 142 at least indirectly supports, with a starter pinion 22, which on the drive shaft 142 such is fastened, that from the drive shaft 142 to the starter pinion 22, a torque is transferable, wherein the starter pinion 22 has an end face 203 and a stop ring 218 is fixedly arranged on the drive shaft 142. It is provided that the starting pinion 22 on the end face 203 has a recess 206 in which the stop ring 218 is arranged, which prevents an inadmissible spreading of the securing ring 209.
  • the locking ring 209 secures the starter pinion 22 against slipping off the drive shaft 142nd
  • the stop ring 218 has an annular seat portion 226 through which the stop ring 218 is centered on the drive shaft 142. From a radially further outer point of the stop ring 218, a collar 220 protrudes in the axial direction from the starting pinion 22, which engages over the securing ring 209. Beyond the securing ring 209, the collar 220 has a plastic deformation 223. By this deformation 223, an undercut 240 is formed between the seat portion 226 of the stopper ring 218 and the plastic deformation 223. The stop ring 218 engages around the locking ring 209 and thus prevents a radial expansion of the locking ring 209 and thereby an axial displacement.
