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.

Sequential gear shifter

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.

Pedally propelled vehicle multi-speed gear system

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.

Coasting clutch and a multispeed gear system with such coasting clutch

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.
