Abstract

The hitherto straight crank arms which connect the shaft and the pin are angled, it being possible to vary the degree of angling. The angling ensures that the connecting rod transmits energy to the crank pin until it reaches bottom dead centre. In the hitherto straight crank arm, the downward movement of the connecting rod ceases in a retarded manner at bottom dead centre. In the present invention, the downward movement of the crankshaft makes a direct and continuous transition into the upward movement, without retardation. In contrast to the hitherto retarded progress of the movement, this continuous movement of the crank pin and connecting rod gives rise to a fuel-saving and economical effect. To save fuel is automatically to emit less exhaust gas. Rounded continuous movements also contribute to smooth running of an engine. This sequence of movements will also have a favourable effect on all moving assemblies of the engine.

Description

Kurbel - Trieb.Crank drive.

Vorliegende Erfindung bezieht sich auf die Abwicklung von Bewegungen, bei welcher Energieen übertragen, in Drehbewegung umgesetzt werden.The present invention relates to the handling of movements, at which energies are transferred, converted into rotary motion.

In meiner Patentanmeldung P 34 11 008. 9 vom 22,3.84 habe ich a uf die Nachteile bei bisheriger Kraftübertragung von a uf-u. abgehender Bewegung in drehende Bewegung hingewiesen, und zwar wird im uneteren Drittel einer Kurbelbewegung keine Energie mehr in Drehbewegung umgesetzt, bedingt durch die Kurbelstellung.In my patent application P 34 11 008.9 of 22.3.84 I have a uf the disadvantages of previous power transmission from on-u. outgoing movement in rotating movement indicated, namely in the lower third of a crank movement no more energy converted into rotary motion, due to the crank position.

Gena u diese Konstellation von Pleuel und Kurbel im Automotor verhindert, daß im unteren Drittel der Bewegung von Pleuel u. Kurbel, Energie abgegeben werden kann.Exactly u prevents this constellation of connecting rod and crank in the car engine, that in the lower third of the movement of the connecting rod and crank, energy is given off can.

Wenn dieser Winkel geändert wird, sodaß die Energie des Pleuels günstiger auf den Kurbelzapfen einwirken kann, so wird weniger Energie verloren gehen und Kraftstoff gespart werden.If this angle is changed, the energy of the connecting rod becomes more favorable can act on the crank pin, so less energy will be lost and Fuel can be saved.

Beschreibung : Erfindungsgemäß werden die Kurbelarme welche Kurbelwelle und Kurbeiza pfen verbinden abgewinkelt, um den angestrebten Effekt Energie zu gewinnen, zu erzielen.Description: According to the invention, the crank arms are which crankshaft and Kurbeiza pfen connect angled to gain the desired effect of energy, to achieve.

Fig. 1 zeigt Kurbelwelle W und Kurbelzapfen Z Kurbelwelle W ist mit Kurbelzapfen Z durch den Kurbelarm A verbunden. Dieser Kurbelarm A schraffiert gezeigt, ist a bgewinkelt, Pleuelstange P zeigt die Richtung der einwirkenden Energie a uf Kurbelza pfen Z an.Fig. 1 shows crankshaft W and crank pin Z crankshaft W is with Crank pin Z connected by crank arm A. This crank arm A shown hatched, is angled, connecting rod P shows the direction of the acting energy Crank Z.

Fig. 2 zeigt den normalen Bewegungsablauf einer Kurbel umdrehung.Fig. 2 shows the normal sequence of movements of a crank rotation.
