Description

Es sind Schaltwerkswechselgetriebe bekannt, bei denen die Schubbewegung der Schaltstange von der Koppel eines Kurbeltriebes abgeleitet wird.There are switching gear change gear known in which the thrust movement of the Shift rod is derived from the coupling of a crank mechanism.

S Erfindungsgemäß wird nun ein solches Schaltwerksgetriebe dadurch weitergebildet, daß eine weitere Schubbewegung von 'der verlängerten Kurbelschwinge hergeleitet wird und daß die Schaltstangen paarweise an diesen beiden Bewegungspunkten -angelenkt sind, welche bei einer bevorzugten Ausführungsform von der Schaltwerkswelle aus rechtwinklig zueinander liegen.According to the invention, such a manual transmission is now further developed by that a further thrust movement derived from 'the extended crank arm and that the shift rods are articulated in pairs at these two points of movement are, which in a preferred embodiment of the derailleur shaft from lying at right angles to each other.

Bei der Bewegungsübertragung gehen somit die Schaltbewegungen nacheinander und sich übergreifend vor sich, so daß keinerlei Pausen in der Übertragung auftreten und eine gleichmäßige, stoßfreie Kräfteübertragung bei allen in Betracht kommenden Drehzahlen stattfindet, wodurch die Übertragung größerer Kräfte ermöglicht wird.When the movement is transmitted, the switching movements go one after the other and overlapping in front of you, so that there are no pauses in the transmission and a uniform, shock-free transmission of forces at all possible speeds takes place, whereby the transmission of larger forces is made possible.

Auf der Zeichnung ist das Schaltwerkswechselgetriebe schematisch veranschaulicht. Der Kurbeltrieb wird hierbei von der Welle k mit dem Stein / des Exzenters m gebildet. An den Verlängerungen p der Kurbelschwinge η sind die Schaltstangen u, v, an den Verlängerungen 0 über dem bei q drehbaren zweiarmigen Hebel r die Schaltstangen s, t angelenkt. Die Schaltstangen s, t sind scherenartig mit den Anlenkarmen e1 der Schaltstange e zweier nebeneinanderliegender Schaltwerke verbunden, während die Schaltstangen U1 ν mit den Anlenkarmen e1 von Schaltringen zweier weiterer Schaltwerke in Verbindung stehen, so daß die beiden Bewegungspunkte von der Schaltwerkswelle aus rechtwinklig zueinander liegen.In the drawing, the gear change gearbox is illustrated schematically. The crank mechanism is formed here by the shaft k with the stone / the eccentric m . The shift rods u, v are hinged to the extensions p of the crank arm η , and the shift rods s, t are hinged to the extensions 0 via the two-armed lever r rotatable at q. The shift rods s, t are connected in a scissor-like manner to the pivot arms e 1 of the shift rod e of two adjacent switching mechanisms, while the shift rods U 1 ν are connected to the pivot arms e 1 of shift rings of two other switching mechanisms, so that the two points of movement from the switching mechanism shaft are at right angles lie to each other.
