Abstract

A gear shifting system derailleur having a derailleur integrable with devices having a positionable chain, belt and/or a plurality of sprockets. The derailleur includes, a frame, a linear actuator having a housing, two bracket links and a damping element. The linear actuator includes a linearly positionable arm. The bracket links and a damping element are positioned and adapted to apply a biased force against the linearly positionable arm. The damping element is coupled with both the chain pulley and the bracket links, wherein the damping element positions the chain pulley within the derailleur as driven by the bracket links. Wireless and/or wired communications and control modules and pathways are provided to enable user control of the linearly positionable arm. The derailleur may be attached to or comprised within a vehicle, such as a bicycle, a tricycle or a vehicle with more wheels.

Abstract

A damping device includes an annular chamber rotatably coupled with the gear selection assembly; a rotating element rotatably coupled with the chamber and fixedly coupled with a gear guide pulley of the gear selection device; and a damping grease volume, the damping grease volume contained under pressure between the chamber and the rotating element and adapted to transfer force between the chamber and to the rotating element. The damping device may be adapted for integration within a gear selection device and for coupling with a linear actuator of the gear selection device. The damping device may be coupled with both a chain pulley of the gear selection device and the linear actuator, wherein the damping device positions the chain pulley within the gear selection device as driven by the linear actuator. The gear selection device may be attached to or comprised within a wheeled vehicle, such as a bicycle.

Abstract

A wireless control system for engagement with a transmission system for a servomotor coupled with sprocket assemblies of remote controlled systems, and within vehicles, including bicycles, is disclosed. The system selectively shifts a chain to each of a plurality of provided sprockets reduces various complications associated with cable slack and precision shifting among an ordered sequence sprockets. The wireless control system allows a user to direct a derailleur to translate drive means from one position to another along a desired path.
