摘要： An engagement mechanism is provided within the rear hub of a bicycle to allow drive sprockets attached to the rear hub to transmit drive motion from the crankset to the rear wheel. The assembly uses a pair of engaging face gears with saw tooth-shaped teeth to accomplish the torque transfer/freewheeling. While one gear is in a fixed axial position, the other is allowed to move axially along a helical spline. A light spring backs up this moveable gear to hold it against the other. When the moveable gear is rotated in one direction, the teeth having their faces parallel to the axis push against each other squarely, transferring the rotating motion from one to the other. Yet in the other direction of rotation, the faces of the teeth are askew to the axis forming ramps by which the fixed gear pushes the moveable gear away from it along the axis. This allows the teeth of the moveable gear to jump over the teeth of the fixed gear causing no rotating force to be transferred to the other and thus freewheeling. The helical spline acts like a screw thread; in the engaging direction of rotation, it pulls and clamps the movable gear to the fixed gear. Once engaged, the helix continues to apply force to hold the two gears together. Because of this effect, the teeth of the gears can be made very small allowing upwards of 100 engagements per turn and of lighter materials such as aluminum rather than steel.
摘要翻译：在自行车的后轮毂内设置有接合机构，以允许附接到后轮毂的驱动链轮将驱动运动从曲柄组传递到后轮。该组件使用一对具有锯齿形齿的接合面齿轮来实现扭矩传递/续流。当一个齿轮处于固定的轴向位置时，另一个齿轮允许沿着螺旋花键轴向移动。轻型弹簧支撑这个可移动的齿轮，使其抵住另一个。当可移动齿轮沿一个方向旋转时，具有平行于轴线的表面的齿正对着彼此推动，将旋转运动从一个传递到另一个。然而，在另一个旋转方向上，齿的表面对于轴线形成斜面是歪斜的，通过该轴线形成斜面，固定齿轮沿着轴线推动可移动齿轮离开它。这允许可移动齿轮的齿跳过固定齿轮的齿，而不产生旋转力传递到另一个齿轮并因此自由转动。螺旋花键像螺纹一样起作用; 在接合旋转方向上，它将可移动齿轮拉动并夹紧到固定齿轮。一旦啮合，螺旋线继续施加力将两个齿轮固定在一起。由于这种效果，齿轮的齿可以变得非常小，允许每回合上升100次接合和较轻的材料，例如铝而不是钢。

摘要： A ratchet mechanism of a hub assembly is located between the hub and the tubular portion, and includes a driving member which is movable linearly in the tubular portion. One side of the driving member has a cone-shaped first ratchet portion located axially and is composed of two triangular contact surfaces. A passive member is fixed in the hub and has a cone-shaped second ratchet portion which is engaged with the first ratchet portion. A returning member is located between the hub and the driving member. The passive member is fixed to the hub easily. By the triangular cone-shaped first and second ratchet portions, the contact are and the friction between the ratchet portions are reduced, and the engagement and disengagement is more quick and smooth.

摘要： A high efficiency bicycle hub for near frictionless free wheeling comprising a hub having a toothed engagement ring, a driver having a retractable engagement member that can engage and disengage from the hub, and a retraction device to facilitate a disengaged configuration. The retraction device comprises a retaining ring having retraction members and the retractable engagement member comprises reciprocal retraction members to “catch” the retraction member to maintain a disengaged configuration. In use, forward rotation of the driver engages the retractable engagement member with the toothed engagement ring of the hub to drive the hub. Reverse rotation of the driver rotates the reciprocal retraction members underneath or behind the retraction member thereby disengaging the driver from the hub.

摘要： A directional transmission mechanism, a directional sprocket apparatus using the directional transmission mechanism, and a pedal device using the directional sprocket apparatus are disclosed. The directional transmission mechanism includes a driving shaft, an output shaft, a co-rotating wheel, a reverse-rotating wheel, and a switching mechanism. The co-rotating wheel set drives the output shaft to rotate in a direction that is the same as that of the driving shaft. The reverse-rotating wheel set drives the output shaft to rotate in a direction opposite to that of the driving shaft. The switching mechanism switches the driving shaft to drive the co-rotating wheel set or drive the reverse-rotating wheel set to rotate, so as to enable the output shaft to rotate directionally. The co-rotating wheel set is connected with the driving shaft and the output shaft, and the reverse-rotating wheel set is connected with the driving shaft and the output shaft.

摘要： A freewheel mechanism comprising two coaxial carrying members for eventually transmitting torque there between, being both members axially fixed but rotatably mounted along an axis. This mechanism further comprises longitudinal pawls housed in cavities, predominantly radially disposed in one of the carrying members, arranged to engage and disengage with a toothed ring placed between said carrying members. This mechanism allows a partial declutch of the carrying members, due to said toothed ring is always forced by longitudinal pawls, to slide bi-directionally in the axial direction, being declutching the axial movement from a first clutch position corresponding to non-freewheeling, to a second declutch position corresponding to freewheeling, and being clutching the axial movement of the toothed ring from the second declutch position to the first clutch position.
