Definitions

  • the invention relates to a bicycle with a frame, a sprung rear wheel swing arm carrying a rear wheel, which can execute a movement in relation to the frame in which the rear wheel moves on a trajectory, and a transmission integrated in a drive train with a in one Housing arranged transmission input and a transmission output.
  • Such a bicycle is known for example from DE 40 01 728 A1.
  • a derailleur system is integrated between the pedal cranks and the rear wheel hub in the gear housing. From the chainring connected to the cranks, a chain runs over two tensioners to the sprockets of the derailleur. The output is formed by the large outer sprocket, over which a chain runs to the sprocket connected to the rear wheel.
  • the derailleur has the disadvantage that after the actual bicycle frame has been manufactured must be mounted on the frame from the outside. Reaction forces from the chain drive lead to movements of the rear wheel suspension, which results in a rocking. In particular, when large forces are introduced into the drive train, as they have to be applied when driving uphill, a rocking suspension is noticeably noticeable for the driver.
  • a generic bicycle is characterized in that the transmission is integrated into the frame such that the axis of rotation of the transmission output is a maximum of 30 mm from the center of the trajectory of the rear wheel.
  • the distance between the axis of rotation of the rear wheel and the axis of rotation of the transmission output changes so imperceptibly over long distances when the rear wheel is deflected that the chain can compensate for it without having to use an additional chain tensioner.
  • the transmission is integrated into the frame as a load-bearing component, it can be procured as a preassembled unit, and only the other components of the frame then have to be attached to it individually. The manufacturing costs can be reduced. At the same time, however, the variety of frame geometries must be maintained if universal fastening points are provided on the gear housing. Different frame sizes are also easy to implement and different bicycle models can be produced by changing simply trained components.
  • Fastening points are preferably provided on the gearbox housing, at which the tubes forming the frame can be detachably fastened (for example screwed).
  • the frame tubes can also be riveted or soldered.
  • the rear wheel swing arm can be pivotally attached to the transmission housing.
  • the length of the rear wheel swing arm is preferably adjustable, so that changing the wheelbase and tensioning the chain is easily possible.
  • the gearbox input is operatively connected to the pedal crank drive.
  • the gear housing is preferably displaceable with respect to the bottom bracket axis. This allows the primary chain, which runs from the chainring to the transmission input, to be tensioned without the need for an additional chain tensioner. Chain tensioning can also be provided in the bottom bracket, as is common, for example, with tandem bikes.
  • a planetary gear can be used as the gear.
  • the primary drive is arranged within the gear housing.
  • the damper element of the suspension can also be attached to the gear housing.
  • Figure 1 - a bicycle according to a first embodiment in the side view
  • Figure 2 - a bicycle according to a second embodiment in side view
  • Figure 3 - a bicycle according to a third embodiment in side view
  • Figure 4 is an enlarged partial view of the bicycle of Figure 1;
  • Figure 8 - an enlarged partial view of Figure 2.
  • the bicycle consists of the frame 1, the gear 2 integrated in the frame 1, which is connected to the chainring 4 or the pedal cranks 5 via a chain 3.
  • the rear wheel swing arm 6, in which the rear wheel 7 is mounted, is fastened to the transmission 2.
  • a damping element 8 is supported on the seat tube 9 of the frame 1 and the rocker 6 of the transmission 2.
  • the rear wheel 7 is connected to the output 1 2 of the transmission 2 via a chain 1 1 (secondary chain).
  • the rocker arm 2 is overhung via the thin ring bearings 14, 15 arranged in the housing 10 of the transmission 2.
  • the pivot point of the rocker 2 coincides with the axis of rotation A of the output 1 2 of the planetary gear provided with an output pinion 1 3.
  • the length L is constant during spring movements of the rear wheel 7, which is mounted on the dropouts of the rocker 2 via the hub 16. Because the length of the chain L remains constant during spring deflection, there is no need for a complex chain tensioner.
  • the rocker 6 is attached to the housing 10 of the transmission 2. Its length can be changed by means of an adjusting screw 18, so that the relative position of the transmission output 1 2 to the rear wheel 7 can be changed in order to tension the chain 1 1.
  • the rocker 6 is slidably mounted in the guide 1 9. With the screws 20, the rocker 6 is fixed in the guide 1 9 after the tension of the chain 11.
  • a multi-joint construction can also be used in which the center point of the axis of rotation of the trajectory of the rear wheel 7 does not coincide with the pivot point of a swivel arm.
  • the gear housing 10 is provided with side plates 21 which are star-shaped (FIG. 5).
  • the side plates 21 are fastened to the frame 1 by means of screws 22, 23. After loosening the screws 22, 23, the position of the transmission 2 can be changed via the tensioning screw 24, so that the relative distance between the axis of rotation of the drive pinion 25 and the bottom bracket axis 26 for tensioning the chain 3 (primary chain) can be adjusted. It can be seen that the side plates 21 connect the frame 1, which can be broken down into three parts, and give them storage and stability.
  • the Axis 28 of the planetary gear is fixed and transmits the reaction moments via screws 27 to the side plates 21.
  • the swing arm 6 is designed in accordance with that in the bicycle according to Figure 1.
  • the primary drive is arranged here within the gear housing 10 and can be formed, for example, by gear wheels or also by a chain or a toothed belt. Corresponding gears can already be provided on the bottom bracket axis 26.
  • the damper element 8 is supported between the rocker 6 and the transmission 2.
  • a connecting tube 29 is provided between the gear housing 10 and the control tube 28.
  • the rear wheel hub 16 does not require a freewheel, so that it can be designed very easily.
  • the freewheel is provided in the transmission 2.
  • the center point of the trajectory of the rear wheel 6, with respect to the rear wheel 6, lies behind a perpendicular K running through the bottom bracket axis 26.
  • the transmission 2 corresponds to that of FIG. 2. It should only be shown that a variety of frame shapes can be realized if a transmission 2 is integrated into the frame as a load-bearing component.
