A pedally propelled vehicle drive train includes a housing, a crankshaft, an internal multi-speed gear with co-axial input and output shafts, and an electric motor with an output shaft. The crankshaft, the input and output shafts of the internal multi-speed gear and the output shaft of the electric motor are all arranged in parallel.

Pedally propelled vehicle drive system

A pedally propelled vehicle multi-speed gear system with a number of unique gear-ratios, including a main shaft, an epicyclic gear section with an input and an output, the epicyclic gear section being arranged coaxially on the main shaft, the epicyclic gear section including a first and second interconnected epicyclic gear sets, and the first and second epicyclic gear sets including a sun gear, a planetary gear, and a ring gear, the main shaft including a support protrusion extending outwardly, the second sun gear being configured to be slidingly arranged on the main shaft and axially supported by the support protrusion in a direction.

A breathing mechanical power transmission and a pedally propelled vehicle with such power transmission, where the power transmission includes a housing, a first seal, a first axle extending through the first seal and a wall of the housing, wherein the first axle is configured to rotate relative to the housing, and a breather passage configured to release a difference in pressure between the inside and outside of the housing in any three dimensional rotational position of the mechanical power transmission.

A hydraulic one-finger two-way acting gear shift operator for a handlebar includes a housing with first and second cylinder chambers, a first and a second piston with first and second piston rods arranged in the first and second cylinder chambers, a first and a second lever arranged to independently push the first and second piston rods and corresponding pistons longitudinally inside the first and second cylinder chambers, wherein the first and second levers are connected to the housing in first and second pivot points, respectively.

Hydraulic one-finger two-way acting gear shift operator

A sequential gear shift system for two-way operated speed change gear units of manually propelled vehicles. Mirrored, spaced-apart lever operators, are provided with increasing lever stroke ratio, and actuate sequentially with twin mirrored one-way multi-tooth rack-clutch mechanisms, that rapidly engage with a shift element and convert linear torque to rotate the shift element in diametrically opposite directions. The rack-clutch mechanisms may be disengaged from the shift element when returning to normal. The actuating may occur via independent hydraulic operation of an actuator. The actuator housing and load bearing axle of the speed change gear hub are selectively, releasably, and coaxially interconnected into a rigid gear system load bearing axle, and may be combined at any angle, and a shift direction is selectively reversible.

A pedally propelled vehicle multi speed gear system includes a gear mechanism including a main shaft; a hollow first shaft and a hollow second shaft, both axially stationary and rotatably arranged about the main shaft; an epicyclical first gear section arranged about the main shaft between the first and second shafts, and including two radially stacked carrier elements; and a first shift mechanism arranged between the first shaft and the first gear section, and configured to rotationally engage the first shaft with either of the two radially stacked carriers. The first shift mechanism includes two first clutches radially stacked about the main shaft.

A coasting clutch and a gear system with a coasting clutch include mutually facing first and second clutch members. The coasting clutch is arranged to operate in an engaged position, wherein the first and second clutch members are axially in mesh and rotating with the same speed, or overrunning and rotating with different speeds. The coasting clutch includes a coasting mechanism arranged to operate the coasting clutch into a coasting position when the clutch is overrunning. In the coasting position, the first and second clutch members are axially arranged further from each other than in the engaged position.

An interrocker assembly for a transmission includes at least two shift forks for actuating gears in the transmission, each of the at least two shift forks being pivotal and having an end offset relative to each other, at least two actuators cooperating with the at least two shift forks, one of the at least two actuators cooperating with one of the at least two shift forks, and an interrocker being pivotally movable and cooperating with each of the at least two shift forks to securely prevent two gears from being engaged at the same time.

Interrocker assembly

A robust and reliable multi-speed gear system for use on pedally or other manually propelled vehicles, comprising simple epicyclical sectionsin a complex structure, an internal axial tunnel enabling use of a detachable, vertical shear force load carrying through-bolt, a rotatable shift axle, a main shaftnon-rotatably mounted to the vehicle frame, axially floating shift mechanisms, and a hub shellfully enclosing the gear mechanisms. The multispeed hub is robust, light, easily manufactured, offers many speeds and great gear width, and is rigidly securable to the vehicle frame.
