Definitions

  • the invention is based on a starting device for internal combustion engines according to the preamble of the claim.
  • a starter with countershaft is already known, in which the ring gear of the countershaft is clamped together with the intermediate bearing and the cover plate between the end faces of the drive bearing and the housing of the starter motor.
  • it is disadvantageous that there may be breaks in the parts transmitting the torque of the starter motor due to compression and decompression impacts of the internal combustion engine to be turned on, that is, single-track gearboxes and countershaft, as well as in the drive bearing.
  • this danger occurs even more than with ordinary starters, because the translation of the countershaft increases the impact forces by increasing the speed of the parts transmitting the torque from the starter motor to the ring gear.
  • a starter device with countershaft is also known, in which the countershaft is not completed on the transmission side by the intermediate bearing and the cover disk that closes off the countershaft is completely missing.
  • the "solid lubricant" specified as a damping means in this starting device merely forms an overload protection device in the form of a slip or friction clutch and no elastic or resilient damping means.
  • the movement of the parts against each other, between which the solid lubricant is introduced, is unlimited.
  • the solid lubricant is also not elastic and therefore cannot dampen the sudden impact of impacts. Only when a certain size of the impact force is exceeded can the parts connected via the solid lubricant turn abruptly against one another.
  • a countershaft which is connected between a tractor output shaft and a drive shaft for a centrifugal pump.
  • the countershaft has a sun gear, the radially projecting pins of which protrude into slots in a pump housing part, so that the ring gear can rotate somewhat with respect to the housing.
  • cushioning and limiting means bone-like elastic cushions are inserted into the slots only in the circumferential direction of the ring gear on both sides of the pins.
  • the countershaft is not closed on the tractor or pump side, which is not necessary in this case, since the countershaft has a liquid flow through it.
  • the ring gear lies firmly against the pump housing parts by hand and pin, as a result of which undesirable combing noises are transmitted from the countershaft to the pump housing parts.
  • the invention has for its object to provide a starter with a gear and motor side gear with elastic or resilient damping means by which the tips of the shocks caused by the internal combustion engine can be reduced, which also do not increase the length of the starter and for which are suitable for large-scale production.
  • shocks caused by the internal combustion engine to be turned off are reduced by the damping means receiving the pins of the ring gear elastically or resiliently in such a way that the risk of breakage at the parts transmitting the torque of the starting motor is reduced and the armature wears out due to the armature running smoothly Brushing is reduced.
  • the damping means act on one of the torque-transmitting parts, which can move in the manner required for damping the shock peaks without releasing the frictional connection.
  • the damping means also enable a noise-reducing and tolerance-compensating attachment of the countershaft on the starter motor by arrangement on the intermediate bearing and on the ring gear of the countershaft, so that the ring gear can move somewhat relative to the intermediate bearing and the cover plate, the planet wheels and the drive shaft of the starter motor, for which purpose the cover plate is still provided with a guide for the planet gears in the axial direction.
  • FIG. 1 shows a starting device, partly in longitudinal section, and FIG. 2 shows a section along line 11-11 in FIG. 1.
  • a starter has a starter motor 1 with a housing 2, in which an excitation winding 3 is arranged.
  • a drive shaft 4 of the starter motor 1 carries an armature 5 and a commutator 6.
  • the drive shaft 4 is rotatably mounted with its end on the commutator side in a bearing cover 7 and with its other end in a bearing in a blind bore of a gear shaft 8.
  • the gear shaft 8 is supported at one end in an extension of a drive bearing 9. Near its other end, the gear shaft 8 is rotatably received in an intermediate bearing 10.
  • the intermediate bearing 10 is inserted into an enlarged end section 11 of the drive bearing 9.
  • the bearing cover 7 and on the other hand the drive bearing 9 with the inserted intermediate bearing 10 are flanged and fastened to the housing 2 by tie rods 12.
  • an engagement relay 14 is fastened with screws 15 to the drive bearing with the interposition of a sealing part 13.
  • the intermediate storage 10 is designed as an essentially cup-shaped molded part made of plastic, for example polyamide. It has a cylindrical band 16 with three slots 17 offset by 120 degrees. A damping means in the form of an elastic cushion 18, for example made of rubber, is inserted in each slot 17.
  • the cushion 18 is provided with a rectangular opening 19, the extended central axis of which extends in a plane perpendicular to the longitudinal axis of the intermediate bearing 10 and intersects the longitudinal axis.
  • a ring gear 20 of a countershaft designed as a planetary gear is arranged in the intermediate bearing 10.
  • the ring gear 20 is also made as a molded part made of plastic, for example made of polyamide.
  • the ring gear 20 has on its outer shell three staggered at an angle of 120 degrees to each other, extending radially to the central axis of the ring gear 20.
  • the pins 21 protrude into the opening 19 of the associated cushion 18 used in the intermediate bearing 10.
  • the ring gear 20 is thus resilient recorded in the intermediate storage 10 and movable within certain limits relative to the intermediate storage 10.
  • the end of the gear shaft 8 projecting into the intermediate bearing 10 is designed as a flange 22 which serves as a planet gear carrier.
  • axes 23 protrude parallel to the longitudinal axis on the end face of the flange 22.
  • the planet gears 25 mesh with an internal toothing 26 of the ring gear 20.
  • the section adjoining the end of the drive shaft 4 rotatably mounted in the gear shaft 8 is designed as a pinion 27.
  • the pinion 27 is also in mesh with the planet gears 25.
  • the planetary gear is closed on the motor side with a cover plate 28 made of sheet metal.
  • the outer edge of cover plate 28 is clamped between the end faces of intermediate bearing 10 and housing 2, covering slots 17 containing pillows 18 and abutting pillows 18.
  • the cover disk 28 With a sleeve-shaped extension 29, the cover disk 28 surrounds a section of the drive shaft 4 bordering the pinion 27 and projects into a sealing ring 31 of T-shaped cross section inserted in the winding head 30 of the armature 5, through which the drive shaft 4 extends.
  • An annular guide projection 32 is formed on the side of the cover disk 28 assigned to the planetary gear.
  • the planet gears 25 slide on it with their end face, in each case with the “point” of the end face near the tooth base, which is just the most distant from the longitudinal axis of the planetary gear and thus of the pinion 27.
  • the gear shaft 8 has a steep thread section 33 on which a driver 34 is seated.
  • the driver 34 is connected in one piece via a flange 35 to an outer race 36 of a freewheel 37.
  • An inner race 38 is designed as an extension of a starter pinion 39, which is arranged on the gear shaft 8 so as to be rotatable and displaceable.
  • the races 36 and 38 include spaces 40 in which rollers 41 and associated springs, not shown, are accommodated.
  • a cover plate 42 closes the rooms 40.
  • a holding disk 43 is located on its outer end face.
  • the freewheel parts 36, 38, 41, 42, 43 are held together by a housing part 44.
  • a stop ring 45 is arranged on the gear shaft 8 near the bearing extension of the drive bearing 9 that receives the end of the gear shaft 8. Between the starter pinion 39 and the stop ring 45, a ring gear 46 of an internal combustion engine to be rotated projects through a mouth-like opening 47 of the drive bearing 9 into the engagement area of the starter pinion 39.
  • a driver disk 50 is arranged to be axially and radially movable between the first stop part 49 and a second stop part 51.
  • the second stop part 51 lies against a stop ring 52 of the driver 34.
  • the driving plate 50 is articulated on a fork-shaped engagement lever 53.
  • the engagement lever 53 is pivotally mounted on a bearing part 54 which is inserted into recesses in the drive bearing 9.
  • the free end 55 of the engagement lever 53 projects into a slot 56 of a switching rod 57 of a magnet armature of the engagement relay 14, which armature is not shown.
  • a brake disc 58 with an abrasion-resistant coating is fastened to the end face of the intermediate bearing 10 facing the driver 34.
  • the brake disk 58, with the facing end face of the driver 34, acts as an outlet brake when the starter device is switched off after the internal combustion engine has been turned on.
  • the reduction gearbox translates the effect of the loads caused by the ignition shocks into larger forces and faster changes at higher speeds.
  • a resilient receptacle 18 for the ring gear 20 on the intermediate bearing 10 By installing a resilient receptacle 18 for the ring gear 20 on the intermediate bearing 10, a damping is connected in the line which forms the frictional connection between the starting motor 1 and the ring gear 46 of the internal combustion engine to be turned on.
  • the mechanical connection between drive shaft 4 and ring gear 46 is no longer completely rigid.
  • the cushion 18 used as a bearing for the ring gear 20 on the intermediate bearing 10 absorb the ignition shocks caused by the internal combustion engine to such an extent that the rigid parts of the single-track gear and the planetary gear are protected from damage.
