FORWARD AND REVERSE PEDALLING SYSTEM FOR A BICYCLE |
摘要 |
<p>A forward and reverse pedaling system for a bicycle with automatic gear change replacing the derailleur and clutch operating at a very low speed using an engagement wheel (16), all enclosed within a housing case filled with oil. The two wheels (11) and (13), which are themselves driven by rods (9) and (10), make a reciprocating to and fro motion of less than a half turn regardless of the direction of rotation of the drive wheel (1) and drive the wheel (12) followed by the driven wheel (2) via the low speed clutch between the wheels (15) and (16). This system can be applied to any mechanical assembly in which it is required, and is not limited to use in bicycles.</p> |
