Definitions
- the invention relates to a freewheel outer ring and a freewheel gear with freewheel outer ring.
- Freewheel outer rings known from the prior art have a homogeneous load distribution when subjected to only one moment in the circumferential direction.
- a transverse force as is typical, for example, in the case of crankshafts
- the side facing away from the direction of pull is subjected to greater load than the side facing the direction of pull.
- the moment is introduced by means of a connected to a connecting rod (crank) via a connecting rod extension at the freewheel outer ring.
- crankshaft drive is known for example from DE 102 43 533 A1.
- DE 10 2009 031 791 A1 discloses a connecting rod for a freewheel crank mechanism, wherein the connecting rod has a first connecting rod eye for a seat on an eccentric drive and a second connecting rod eye for connection to a freewheel unit.
- the invention has for its object to provide a solution for a uniformly loaded freewheel outer ring according to the preamble of claim 1.

Furthermore, the freewheel outer ring has a freewheel recess, which has an average greater material thickness on the side facing away from the pulling direction of the crank.
- crank which can be connected to the small connecting rod eye, a pulling or pushing force is alternately exerted which causes the freewheel outer ring to oscillate about the one displaced on the axis.
- About an arranged in the large connecting rod eye of the freewheel outer ring freewheel can be offset about the vibrations of the driving crank axis in rotation.
- a plurality of axially adjacent freewheel outer rings are used to drive an axle, which are spaced apart from each other driving the axis.
- a preferred embodiment of the freewheel outer ring is characterized in that the freewheel recess has an average lower material thickness on the side facing the pulling direction of the crank.
- the greater average material thickness is achieved by the fact that the outer ring of the freewheel outer ring is selectively thickened on the side facing away from the direction of pull.
- An average lower material thickness on the side facing the pulling direction is preferably achieved by a Quer4.000reduzi für
- a preferred embodiment of the freewheel outer ring is characterized in that the center of the outer periphery of the large connecting rod eye is displaced laterally relative to the center of the inner diameter of the large connecting rod eye.
- a further preferred embodiment of the freewheel outer ring is characterized in that the outer contour of the large connecting rod eye is eccentric to the inner diameter of the large connecting rod eye.
- crankshaft drive with a drive side and an output side, in which a plurality of previously described freewheel outer rings are arranged on the output side in the axial direction.
- the drive side is connected, for example, to an engine of a vehicle.
- the output side is connected, for example, with the driven axle of a vehicle,
- crankshaft free-wheel transmission is characterized in that it is designed as a crank-CVT transmission.
- an adjustable eccentric drive arrangement is provided with eccentric components on an input shaft which can be driven by a motor and which forms a driving shaft with respect to the transmission, which is connected to a driven shaft via connecting rod-like connecting elements Transmission forms an output shaft.
- the driven wave is through the Transmission of the stroke of the connecting elements driven by means of freewheel devices on the shaft, which are provided between the connecting elements and this shaft.

- FIG. 3 shows a further embodiment of the freewheel outer race 1 according to the invention, in which only part of the outer contour of the large connecting rod eye 3 is eccentric to the inner diameter of the large connecting rod eye 3.
- the small connecting rod 2 is connected via a bolt 12 with a crank 4, which exerts a force on the freewheel outer ring 1.
- a part of the outer contour of the large Pleuelauges 3 is on the acting force of the crank 4 side facing 6 eccentric to the inner diameter of the large Pieuelauges 3.
- the outer contour of the large connecting rod eye is completely eccentric to the inner diameter of the large connecting rod eye 3.
- the outer contours of the large connecting rod eye are shown in detail in Figure 5b.
- FIG. 4 shows a freewheel outer race 1 according to the invention with a roller freewheel 11 in the large connecting rod eye 3 of the freewheel outer race 1.
