A bicycle gearing system includes input and output shafts, two planetary gear systems, and a clutch mechanism. The clutch mechanism includes three clutch presser plates for frictional engagement with two clutch disks and a clutch base. A motor rotates a camshaft formed with cams selectively engageable with cam followers for driving the clutch presser plates to rotate. Steels balls are provided within cavities formed between the clutch presser plates and a clutch housing to convert rotation of clutch presser plates to linear force for frictional engagement with the two clutch disks and the clutch base. Different angles of rotation of the camshaft produce different clutch and gear combinations and different gear ratios.

A marine transmission located within drive housing includes a torque transmitting gear set and a clutch mechanism. The torque transmitting gear set includes top and bottom bevel gears and opposing side idler bevel gears mounted to a pinion shaft. The pinion shaft is mounted on a carrier and the clutch mechanism engages the carrier to rotate with the input shaft to drive the output shaft in the forward direction and engages the carrier to a reaction plate fixed to the drive housing to drive the output shaft in the reverse direction.

The invention relates to a gearbox for vehicles, comprising a planetary gear with a ring gear a sun gear and a planet carrier on which at least one planet gear is rotatable mounted, which ring gear and sun gear engages with the at least one planet gear by teeth; and a gearbox housing surrounding the planetary gear. A first axially movable coupling sleeve is in a first gear position arranged to engage the ring gear with the gearbox housing in a second gear position arranged to engage the sun gear with the planet carrier and in a third gear position arranged to engage the planet carrier with the gearbox housing. A second axially movable coupling sleeve is in the third gear position arranged to engage the ring gear with an output shaft. The invention also relates to a vehicle, which comprises such a gearbox.

A human-electric hybrid powertrain with a continuously variable transmission achieved with the use of a bevel planetary gearset. Two electric motors are utilized to produce a hybrid powertrain with either a driveshaft, chain, or belt driveline. The electric motors combine to produce an infinitely variable range of gear ratios and power assistance to the operator.

In a gear mechanism having a gear stage, the input shaft is oriented coaxially to the output shaft. The first planet carrier is connected to the input shaft for conjoint rotation, e.g., is integrally formed therewith. The first gear wheel is connected to the second gear wheel for conjoint rotation, the first planet gear is connected to the second planet gear for conjoint rotation, and the first crown-toothed gear is connected to the housing for conjoint rotation. The toothing of the first planet gear meshes with the toothing of the first crown-toothed gear, and the toothing of the second planet gear meshes with a crown toothing formed on the second planet carrier. A bearing for rotatably mounting the first and second gear wheel is received in the second planet carrier, the toothing of the first gear wheel meshes with the toothing of the second crown-toothed gear, the second crown-toothed gear is connected to the housing for conjoint rotation, and the toothing of the second gear wheel meshes with a crown toothing of the output shaft.
