A multi-speed gear system (12) for a chain transmission device of a bicycle is provided. The system (12) includes a disc (38) having a front plate (40), a rear plate (42), and a plurality of tooth series concentrically arranged in the disc and a tooth series selector (54). Each of the tooth series has a plurality of tooth blocks (58); the front plate of the disc has a plurality of tooth holes (60); and the rear plate of the disc has a plurality of rear holes. Each of the tooth blocks (58) is either pushed into a corresponding one of the tooth holes (60) or protrudes out of the front plate (40) and the tooth series selector (54) selects one of the tooth series to change speed and makes the tooth blocks of the selected tooth series protrude out of the front plate (40) .
Abstract:
A variable diameter pulley assembly (30) includes a shaft (37) and a pair of pulley sheaves (16, 17) each having a pair of relatively movable guideway disks (32, 33) lying alongside each other. Inner and outer guideway disks (34, 35) of each pair include respectively, first and second series of spiral guideways (32, 33) extending in opposite directions. An integral speed responsive actuator assembly is incorporated into the pulley assembly and includes a housing (44) with two pairs of variable volume fluid chambers (60, 61, 62, 63) and a pair of mirror image speed responsive valves (68, 69) which direct hydraulic fluid under pressure into one or the other of the chambers of each pair to obtain relative movement of a wall separating the chambers, which relative movement can be coupled to the guideway disk sets to change the effective diameter of the pulley assembly (30).
Abstract:
The present invention provides a transmission system (12) comprising a first pulley (11) connected to an output, which may be in the form of a second pulley (111), by a cable (59) such that movement of the first pulley causes rotation of the output. The first pulley comprising an annular recess (25) between a first side (17) of the first pulley and a second side (19) of the first pulley. The annular recess is adapted to receive the cable such that the cable is supported by the first pulley at a first diameter. The first pulley also comprises at least one pair of rings (27) located in the annular recess. The at least one pair of rings is moveable in a lateral direction relative to the sides of the pulley between a spaced condition, wherein the pair of rings do not engage the cable, and a meshed condition, wherein the pair of rings support the cable at a second diameter, the second diameter being larger than the first diameter.

The present invention relates to a continuously variable transmission that steplessly changes gear ratios by changing pulley width, and more particularly, to a continuously variable transmission capable of increasing driving power through increasing the area of contact between a pulley and belt, and capable of quickly changing gear ratios by being able to simultaneously move each pair of conical wheels constituting a driving pulley and a driven pulley, respectively. The continuously variable transmission according to the present invention is provided with a driving pulley and a driven pulley formed with a pair of conical wheels mounted on a rotational axis to face one another and be capable of axial translation, and a belt wound and connected between the driving pulley and the driven pulley, whereby gear ratios are steplessly changed by changing the widths of the driving pulley and of the driven pulley. The transmission further comprises: gear change linkages (50, 50') connected between the driving pulley and the driven pulley for adjusting a gear ratio by axially translating each of the conical wheels constituting the driving pulley and the driven pulley; and a gear change actuator (60) connected to the gear change linkages (50, 50') for receiving a gear change input from the outside and actuating the gear change linkages (50, 50').
