摘要： An improved drum type switch-over mechanism for a speed change device including a speed change pedal shaft and a speed change drum both of which are rotatably supported in axial alignment with one another on a transmission case and which are operatively connected to one another by way of an intermittent feed mechanism so as to allow the speed change drum to be rotated by a unit angle in a predetermined direction on every reciprocatable rotation of the pedal shaft by a predetermined angle. The improvement consists in that the pedal shaft is located in axial alignment with an input shaft of the intermittent feed mechanism, that a sun gear is formed on the input shaft while a plurality of planet gears are mounted on the pedal shaft for meshing engagement with the sun gear, and that a ring gear meshing with the planet gears is firmly fixed to the transmission case. This arrangement of the switch-over mechanism enables the pedal shaft, the input shaft and the speed change drum to be disposed within a limited space, realizing a very compact structure of the switch-over mechanism, a substantial reduction of its mounting space and smaller design dimensions of the speed change device.
摘要翻译：一种用于变速装置的改进的滚筒式切换机构，包括速度改变踏板轴和变速滚筒，它们都被可旋转地支撑在变速器壳体上彼此轴向对准并且彼此可操作地连接间歇进给机构，以使得变速鼓在踏板轴的每一个可往复运动的旋转预定角度上以预定方向旋转单位角。改进之处在于，踏板轴与间歇进给机构的输入轴轴向对准，在输入轴上形成太阳齿轮，而多个行星齿轮安装在踏板轴上，用于与太阳齿轮，并且与行星齿轮啮合的齿圈牢固地固定到变速箱上。切换机构的这种布置使得踏板轴，输入轴和变速鼓能够被布置在有限的空间内，实现了非常紧凑的切换机构的结构，其安装空间大大降低，并且更小变速装置的设计尺寸。

摘要： A change speed gear mechanism for a motorcycle is controlled by a shift drum mounted to turn. First and second cam plates are coaxially fixed to the shift drum and means are provided for turning the cam plates for moving the shift drum in either direction in equal angular increments between a high speed position and a low speed position, each angular increment being larger than the angular value calculated by dividing 360.degree. by the total number of gear ratios provided by the speed change gear mechanism.

摘要： A system and method for simple transmission of a multi-speed bicycle is provided. A bicycle can have a transmission that can be toggled by a kickback shifting mechanism. A rear wheel hub can support a freewheel having a high speed gear sprocket and a low speed gear sprocket with dedicated chains to create dedicated gear-shifting. Rotating the pedal shaft in the non-drive direction approximately one-quarter rotation can toggle the transmission between the first gear ratio and the second gear ratio with a shifting surface that alternately allows driving engagement of the high speed gear sprocket with the rear wheel driver.

摘要： A controller drives a shifting actuator to move a first engagement member from an original position of a first engagement portion in one direction along a relative motion path and acquires first position information representing a first position, the first position being a position where the first engagement portion moved in the one direction contacts a second engagement portion. The controller drives the shifting actuator to move the first engagement member from the original position in the other direction along the relative motion path and acquires second position information representing a second position where the first engagement portion moved in the other direction contacts the second engagement portion. The controller calculates a center position of the first engagement portion on the relative motion path from the acquired first position information and the acquired second position information, compares the calculated center position to the original position.

摘要： A gear shift (100) is described for a saddle vehicle (M) comprising a shift lever (110), a selecting element (130) actuated through the shift lever (110) and a selector drum (150) connected to the selecting element (130) and adapted to engage gears. The gear shift (100) further comprises a block device (140) functionally connected to the selector dmm (150) and configured so as to be switched between: a first configuration, wherein the block device (140) allows engaging a first gear (I) from a neutral gear (N) in a first change direction (Up), a second configuration, wherein the block device (140) inhibits the subsequent engagement of the neutral gear (N) from the first gear (I) in a second change direction (Dwn). Control means (120) of the block device (140) are further provided, actuated by a rider (G) so as to define a third configuration, wherein the block device (140) is disabled in order to allow engaging the neutral gear (N) from the first gear (I) in the second change direction (Dwn).

摘要： A rotation position detection device includes a change drum, a magnetic field generator, and a magnetic field detector. The magnetic field generator is fixed to the change drum and rotates along with the change drum to differentiate an ambient magnetic field. The magnetic field detector is formed separately from the magnetic field generator and fixed to a position at which a magnetic field changes in response to rotation of the magnetic field generator so as to detect the magnetic field and output a signal that depends on the rotational position of the change drum on the basis of the detection result.
