Abstract

Der Schutz auf den RZT-Zylinder bezieht sich auf folgende, ausschließlich bei unserem RZT-Zylinder realisierte Details: • Die auf einen Aussendurchmesser von mindestens 54,5 mm vergrößerte Laufbuchse eines RZT-Zylinders für Simson M53/M54/M74-Motoren. (Entscheidend ist das kleinste Maß der Laufbuchse im Aussendurchmesser) • Die vergrößerte Arbeitshöhe eines RZT-Zylinders für Simson M53/M54/M74-Motoren auf 45 mm und mehr (entscheidendes Maß ist Unterkante Überström- und Auslasskanäle bis Oberkante Zylinder). • Den vertikal geteilten Auslasskanal („Doppelauslass”) eines RZT-Zylinders für Simson M53/M54/M74-Motoren.The protection for the RZT cylinder is based on the following details, which are only applied to our RZT cylinder: • The bore of an RZT cylinder enlarged to an outer diameter of at least 54.5 mm for Simson M53 / M54 / M74 engines. (Decisive is the smallest dimension of bushing in outer diameter) • The increased working height of a RZT cylinder for Simson M53 / M54 / M74 engines to 45 mm and more (decisive dimension is bottom edge of overflow and exhaust ducts to upper edge of cylinder). • The vertical split outlet port ("dual outlet") of an RZT cylinder for Simson M53 / M54 / M74 engines.

Description

Geschützt werden soll ein Zylinder für Simson-Motoren der Baureihen M53/M54/M74. Der Zylinder – im Text „RZT-Zylinder” genannt – weist einige technische Änderungen gegenüber dem Originalzylinder mit Zweck eine höhere Motorleistung zu ermöglichen. Im Einzelnen sind das folgende Details:

  • • Eine auf 55 mm (Aussen)durchmesser vergrößerte Zylinderlaufbuchse um darin Kolben bis 51 mm Durchmesser verbauen zu können (original maximal 46,5 mm). Um eine größere Stabilität des Zylinders sowie eine bessere Wärmeableitung zu ermöglichen ist dabei die Laufbuchse in den Kühlkörper nicht nachträglich eingeschrumpft sondern umgossen, die Laufbuchse dient während der Produktion des RZT-Zylinders als innerer Gusskern. Siehe dazu Zeichnung 1, Detail A.
  • • Eine größere Arbeitshöhe des RZT-Zylinders um Kurbelwellen zu verbauen die einen größeren Hub als 44 mm (Originalmaß) aufweisen. Maßlich entscheidend ist hierfür das Maß von der Unterkante der Überströmkanäle (a) und Auslasskanal (b) bis zur Oberkante des RZT-Zylinders. Dieses Maß gibt den sinnvoll zu benutzenden Maximalhub an und beträgt beim Originalzylinder 44 mm. Bei dem zu schützenden RZT-Zylinder liegt dieses Maß bei über 45 mm. Siehe dazu Zeichnung 2, Detail B.
  • • Einen vertikal geteilten Auslasskanal („Doppelauslass”) um einen größeren Querschnitt des Auslasskanals zu ermöglichen. Der Auslasskanal verfügt über einen vertikalen Steg in der Laufbuchse, der sich im dahinterliegenden Kühlkörper durch angegossenes Alumimiummaterial fortsetzt. Siehe dazu Zeichnung 1, Detail C sowie Zeichnung 2 und 3.
A cylinder is to be protected for Simson engines of the M53 / M54 / M74 series. The cylinder - called in the text "RZT cylinder" - has some technical changes compared to the original cylinder with the purpose to allow a higher engine output. Specifically, these are the details:
  • • A cylinder liner enlarged to 55 mm (outside) diameter to fit pistons up to 51 mm in diameter (original maximum 46.5 mm). In order to allow greater stability of the cylinder and a better heat dissipation while the bushing in the heat sink is not subsequently shrunk but encapsulated, the liner is used during the production of the RZT cylinder as the inner casting core. See drawing 1, detail A.
  • • Install a larger working height of the RZT cylinder around crankshafts that have a stroke greater than 44 mm (original dimension). The measure of the lower edge of the overflow channels (a) and outlet channel (b) up to the upper edge of the RZT cylinder is decisively decisive for this. This dimension indicates the useful maximum stroke and is 44 mm for the original cylinder. For the RZT cylinder to be protected, this dimension is over 45 mm. See drawing 2, detail B.
  • • A vertically divided outlet channel ("double outlet") to allow a larger cross-section of the outlet channel. The outlet channel has a vertical web in the bushing, which continues in the underlying heat sink by cast aluminum material. See drawing 1, detail C and drawing 2 and 3.
