摘要： One-way clutches having different numbers of pawls (1006, 1007) and pockets in a 'vernier' arrangement minimise relative rotation between the two clutch halves (101, 102) in the engagement direction. Noise is also reduced. Directionally sensitive biasing means (1008) rather than springs are used in one-way clutches for extending or retracting inertially balanced swivelling pawls (1006,1007). In another embodiment, a reversible one-way clutch uses a gear train to drive a worm screw synchronised with teeth on a driven worm gear, when freewheeling. Controlled backlash places the worm in either a contact mode (when engagement occurs) or a non-contact (disengaged) mode when driven in an opposite direction.

摘要： A multi-speed transmission (20) for transmitting power between a first shaft (26) and a second shaft (32) includes a plurality of gear sets (38), a plurality of connector gears (40) corresponding to the plurality of gear sets (38) and a shifting mechanism (42). Each gear set (38) includes a first gear (30) rotatably disposed about the first shaft (26), a uni-directional free wheeling mechanism (28) between the first gear (30) and the first shaft (26), and a second gear (36) coupled to the second shaft (32). The uni-directional free wheeling mechanism (28) permits the first gear (30) to freely rotate about the shaft (26) when the first gear (30) rotates in a preselected direction relative to the rotation of the first shaft (26) and locks the first gear (30) to the first shaft (26) at all other times. Shifting mechanism (42) moves at least one connector gear (40) to interconnect at least one gear set (38).

摘要： A ratchet mechanism for a bicycle hub includes a first hub member (20, 20') and a second hub member (7, 75), wherein the first hub member (20, 20') and the second hub member (7, 75) are rotatable relative to each other. A pawl (30, 30') is supported by the first hub member (20, 20'), a ratchet tooth (11, 11') is supported by the second hub member (7, 75), and a biasing mechanism (23, 95) is provided for biasing the pawl (30, 30') toward the ratchet tooth (11, 11'). A pawl control mechanism (60, 100) is responsive to relative rotation of the first hub member (20, 20') and the second hub member (7, 75) for allowing the pawl (30, 30') to contact the ratchet (11, 11') when the first hub member (20, 20') and the second hub member (7, 75) rotate relative to each other in one direction and for preventing the pawl (30, 30') from contacting the ratchet tooth (11, 11') when the first hub member (20, 20') and the second hub member (7, 75) rotate relative to each other in an opposite direction.

摘要： A free wheel of high rigidity having a play angle ideal for a sport bicycle. A ratchet mechanism (35) is interposed between a hub shaft (2) provided on a rear hub and a hub barrel (6) rotatably provided on the same shaft. The ratchet mechanism (35) transfers rotation only in one direction to the hub barrel (6) from a sprocket gear provided on a gear table (33). Assuming that the number of ratchet teeth (31) is N, and that the number of phase different claws (34) is n, 360 degrees/(N*n) is less than 4.0 degrees, preferably between 2 and 2.4 degrees.

摘要： Die Erfindung betrifft eine Steuereinrichtung für Klinkengesperre für Fahrrad-Mehrgangantriebsnaben, umfassend wenigstens eine nach radial innen angefederte Klinke (2a,2b) mit mindestens einer Feder (3a,3b), wobei dieses Klinkengesperre einen Ringkörper (5) in einer Drehrichtung mit einer Nabenachse (1) drehfest kuppelt mit mindestens einer zur Nabenachse (1) parallel verlaufenden Steuereinrichtung zur Steuerung des Klinkeneingriffs zwischen dem Ringkörper (5) und der Nabenachse (1), wobei die Steuereinrichtung aus mindestens einem Steuerschieber (4) besteht, der mindestens einen Nocken (4a) aufweist, mit Hilfe dessen die Klinkengesperre außer Eingriff zu bringen sind. Von Vorteil ist eine solche Einrichtung zur Schaltung von Klinkengesperren teilweise sogar unter Last und mit der Möglichkeit, mehr als ein Klinkengesperre mit einem einzigen Steuerschieber (4) aus- oder einzusteuern.
摘要翻译： 用于自行车的轮毂通常可以具有用于非旋转地连接到自行车的框架的轴，围绕车轴可旋转地安装的轮毂体以及可旋转地安装在车轴上的驱动元件。 多个传动元件可以优选地设置在轴和轮毂体之间，用于将驱动力从驱动元件传递到轮毂体，并且传动元件提供的各种传动比之间的选择可以优选地通过选择性地接合 棘轮机构和用于选择性地接合和分离棘轮机构的控制装置。 棘轮机构可以由至少一个棘爪提供，至少一个爪被至少一个弹簧径向向内偏置，以使环体在一个旋转方向上与轴不旋转地联接。 还可以具有平行于轮毂轴延伸的控制装置，以控制棘爪在环体和轴之间的接合，由此控制装置可具有至少一个凸轮的控制板。 凸轮可以被配置为脱离棘轮机构。 这种装置即使在负载下也有利于移动棘轮机构，并且可以利用单个控制板来接合或分离多于一个的棘轮机构。

摘要： An electronic automatically decoupling hub assembly (1000) is disclosed herein. The assembly has an axle (15) and a hub shell (1005) rotationally positioned about the axle. A controller (1010) provides automatic activation/deactivation signals to an inductor (1015). The assembly has a bearing (1025) rotationally positioned about the axle and a rachet ring (1020), having a plurality of teeth, rotationally positioned about the bearing. One or more pawls (1030) are provided to engage with at least some of the teeth of the ratchet ring and a seal (1035) is used to contain the pawls within the assembly. A cassette body assembly (1040) is coupled with the rachet ring and an end cap (1045) is used to prevent a contaminant from entering into the decoupling hub assembly.

摘要： A bicycle system comprising a suspension (38,34), a chain (19) and a disengageable derailleur assembly (17), the disengageable derailleur assembly comprising: a P-knuckle assembly (510) comprising a clutch plate (635); and a cage assembly (565) having a cage-assembly counterpart (650); wherein the clutch plate selectively and frictionally engages the cage-assembly counterpart based on manual or automatic inputs from the bicycle system: the disengaging occurring when performance is paramount to eliminate the inefficiencies caused by suspension induced chain growth; and the reengaging occurring as needed to ensure the chain stays in an appropriate location to properly propel the bicycle system.
