REAR WHEEL AXLE, AS WELL AS BICYCLE FRAME AND REAR WHEEL FOR A BICYCLE

摘要

A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted. The driver allows operation with only little energy, since the chain need not be shifted. consequently, the actuation elements require little energy for changing the drive between the crank axle and the wheel hub of the bicycle, so that it is pre-eminently suitable for these actuation elements and their operation to be executed as an electrical version.

主权项

1. A bicycle (301) comprising:
a frame (303) comprising a front fork (305) and a rear fork (307), as well as an axle housing, a front wheel (311) and a rear wheel (313) fitted to the front and rear fork respectively, a drive axle which is bearing-mounted in the axle housing, at least a single front sprocket (319) which is connected to the drive axle (317), at least a single rear sprocket (321) which is connected to a wheel hub (201) of the rear wheel (313), a chain (323) threaded around the front and rear sprocket, a transmission (31) comprising at least two drives between the drive axle (317) and wheel hub (201) of the rear wheel (313) and provided with actuation means (81) for switching between the drives, and operating means (325) for operating the actuation means,where the actuation means (81) of the transmission (31) are electrically actuated and the operating means (325) are electrically coupled to the actuation means, andwhere a storage element (337) for storing electrical energy is coupled to the actuation means and/or operating means,wherein the bicycle comprises a generator (339) or current generating means which converts/convert motion energy to current, as well as a charger (341) connected to this generator or current generating means and to the electrical energy storage element (337) for charging the storage element.
