Abstract
Freiausstoßender Starter für Brennkraftmaschinen mit einem eine Antriebswelle (10) koaxial umschließenden Starterritzel (11), das mit einem Hohlschaft (111) auf der Antriebswelle (10) axial verschieblich gelagert ist und mit einem an dem vorderen Ende des Hohlschaftes (111) ausgebildeten Ritzelkranz (112) in einen Zahnkranz (12) der Brennkraftmaschine einspurbar sowie mit einem im Innern des Hohlschaftes (111) ausgebildeten Anschlag an einem auf der Antriebswelle (10) festgelegten Gegenanschlag anlegbar ist, der von einem zweiten Anschlagring (24) gebildet ist, wobei der Hohlschaft (111) einen über die Schaftlänge im wesentlichen konstanten Innendurchmesser aufweist und daß der Anschlag von einem in dem Hohlschaft (111) axial unverschieblich angeordneten, die Antriebswelle (10) mit Spiel umschließenden ersten Anschlagring (23) gebildet ist, dadurch gekennzeichnet, dass der zweite Anschlagring (24) mittels eines einerseits im Außenmantel der Antriebswelle (10) und andererseits in einer in der Innenwand des zweiten Anschlagrings (24) jeweils eingestochenen Nut (29, 30) einliegt und ein Abstand zwischen dem zweiten Anschlagring (24) und dem Innern des Hohlschaftes vorhanden ist.Free-ejecting starter for internal combustion engines with a drive shaft (10) coaxially enclosing starter pinion (11) which is axially displaceably mounted with a hollow shaft (111) on the drive shaft (10) and with a at the front end of the hollow shaft (111) formed pinion ( 112) in a ring gear (12) of the internal combustion engine can be engaged and with a formed in the interior of the hollow shaft (111) stop on a drive shaft (10) fixed counter-stop can be applied, which is formed by a second stop ring (24), wherein the hollow shaft (111) has a substantially constant over the shaft length inner diameter and that the stop of a in the hollow shaft (111) axially immovably arranged, the drive shaft (10) with play enclosing first stop ring (23) is formed, characterized in that the second Stop ring (24) by means of a one hand in the outer jacket of the drive shaft (10) and on the other hand i n one in the inner wall of the second stop ring (24) respectively recessed groove (29, 30) rests and a distance between the second stop ring (24) and the interior of the hollow shaft is present.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem freiausstoßenden Starter für Brennkraftmaschinen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a free-ejecting starter for internal combustion engines according to the preamble of patent claim 1.

Aus dem Dokument
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Starter mit den Merkmalen des Patenanspruchs 1 hat den Vorteil, daß das Starterritzel bei gleicher Funktionalität und beibehaltener vorteilhafter Kurzbauweise des Starters wegen der durchmesserkonstanten Innenbohrung des Hohlschaftes rationeller und kostengünstiger gefertigt werden kann. Zwar erfordert der in dem Hohlschaft eingesetzte Anschlagring einen weiteren Montageschritt, doch kann dieser vollautomatisch ausgeführt werden. Die dabei entstehenden Mehrkosten bei der Montage sind jedoch kaum nennenswert in Hinblick auf die Kostenvorteile, die durch das jetzt mögliche Übergehen auf rationelle Fertigungsmethoden zur Herstellung des Starterritzels, z. B. Fließpressen, erzielt werden. Durch diese konstruktive Maßnahme lassen sich Anschlag und Gegenanschlag an Hohlschaft und Antriebswelle fertigungstechnisch einfach und kostengünstig realisieren.The starter according to the invention with the features of claim 1 has the advantage that the starter pinion with the same functionality and retained advantageous short construction of the starter because of the diameter constant inner bore of the hollow shaft can be made more rational and cost-effective. Although the stop ring used in the hollow shaft requires a further assembly step, this can be carried out fully automatically. However, the resulting additional costs during assembly are hardly appreciable in view of the cost advantages resulting from the now possible transition to rational production methods for the production of the starter pinion, z. B. extrusion, can be achieved. By this design measure can be stop and counter-stop on hollow shaft and drive shaft manufacturing technology easily and inexpensively.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Patentanspruch 1 angegebenen Starters möglich.The measures listed in the further claims advantageous refinements and improvements of the claim 1 starter are possible.
Der Gegenanschlag ist ebenfalls als Anschlagring ausgebildet. Die beiden Anschlagringe sind bevorzugt jeweils mittels eines Federrings festgelegt, der einerseits in einer in den jeweiligen Anschlagring eingestochenen Nut und anderseits in einer in die Abtriebswelle bzw. den Hohlschaft eingestochenen Nut einliegt.The counter-stop is also designed as a stop ring. The two stop rings are preferably each determined by means of a spring ring, which rests on the one hand in a recessed into the respective stop ring groove and on the other hand in a pierced in the output shaft or the hollow shaft groove.
