Motor car i.e. electric car, has complete circumferential groove formed in space of rotary piston within region of middle of eccentric shaft for distribution of lubricant and/or collection of lubricant for supply

The car (101) has a replaceable range extender (102), and a rotary piston comprising a rotary piston cavity. A lubrication system guides a lubricant, and an area is limited by a side piece opposite to an outer side of a support side part. A complete circumferential groove is formed in a space of a r...

More Information
Summary:The car (101) has a replaceable range extender (102), and a rotary piston comprising a rotary piston cavity. A lubrication system guides a lubricant, and an area is limited by a side piece opposite to an outer side of a support side part. A complete circumferential groove is formed in a space of a rotary piston within the region of middle of an eccentric shaft for distribution of lubricant and/or collection of the lubricant for supply. A valve is laid out for prevention of an uncontrolled return of the lubricant. An independent claim is also included for a method for lubricating a rotary piston engine in a replaceable rank extender for a motor car. In einem Rotationskolbenmotor (209) in einem Kraftfahrzeug (101) mit einem auswechselbaren Range Extender (102) ist ein Bereich vorgesehen, der begrenzt wird durch eine Außenseite eines Trägerseitenteils (201) und eine Außenseite eines dem Trägerseitenteil gegenüberliegenden Seitenteils (214). Innerhalb dieses Bereichs sind zumindest eine die Exzenterwellenmitte (224) umlaufende Nut zur Schmiermittelverteilung und/oder -sammlung sowie zumindest eine Zuführung für das Schmiermittel zum Raum des Rotationskolbens (213) vorgesehen.
