Abstract:
An automatic bicycle drivetrain shifting apparatus comprising a bicycle drive chain derailer apparatus powered by a servo gearmotor and controlled through a highly adaptable user interface serving to automatically alternate drive chain position between available bicycle drive sprockets based on user preset and in real time modifiable criteria and additionally making use of critical chain driver apparatus serving to ensure chain motion is always available to satisfy derailer operation requirements often prevalent during coasting and stopping where the bicycle speed changes while pedaling motion has ceased.

Claim (Index 22):
22 - An automatic bicycle shifter and chain driver apparatus comprising:\n a) a bicycle rear wheel hub drive chain derailer powered by an electrical gearmotor including a rotational position encoder, b) said bicycle drive chain in constant engagement with one of a plurality of a bicycle rear wheel hub power transmission drive chain sprockets, c) an electronic control system with a hardwired connection to said rotational positional encoder and including a shaft angle resolver, a revolutions counter and a nonvolatile memory for storage of readings of said rotational position encoder corresponding to alignment positions between said rear wheel hub drive chain derailer and said rear wheel hub power transmission drive sprockets, d) said electronic control system further including a servo motor controller with a power connection to said gearmotor of said bicycle rear wheel hub drive chain derailer, e) a bicycle speed sensing means producing an electric signal in a known relationship to road speed of said bicycle and including a hardwire connection to said electronic control system, f) an electronic user interface for entering readings of said rotational position encoder corresponding to said alignment positions and corresponding speed shifting thresholds of said bicycle rear wheel hub drive chain derailer into said nonvolatile memory of said electronic control system, g) a drive chain forward movement sensor including a hardwire connection to said electronic control system, h) said rear wheel hub slaved to a pawl and ratchet assembly through attachment to ratchet hub thereof embodying a plurality of ratchet pockets and internally housing a rotating pawl hub fitted with a corresponding plurality of pawls of predominantly circular midsections urged in outward radial direction by means of a corresponding plurality of compression springs and adapted for engagement with said plurality of ratchet pockets, i) said pawl hub including a radial extension retaining said pawls between a corresponding plurality of axial inner and outer gib extensions between mating concentric circular peripheries, including mating features limiting inward and outward radial movement of said pawls and embodying said corresponding plurality of compression springs urging said pawls in outward radial direction, and an axial extension internal and rotationally secured to said bicycle rear wheel hub power transmission drive chain sprockets, j) said plurality of pawls further adapted for engagement with said ratchet pockets upon forward actuation of bicycle pedals, resultant forward movement of said drive chain and forward rotation of said bicycle rear wheel hub power transmission drive chain sprockets, k) a pawls collapsing and drive chain driving apparatus including an electrically powered chain driver motor slaved to said electronic control system, a thereto connected power transmission gearset with an affixed rotary connection to a power transmission cam hub concentric to said pawl hub and including a radial extension embodying a plurality of cams serving to draw said pawls in inward radial direction through mating recessed features thereof, in turn forcing corresponding rotation of said pawls, said pawl hub, thereto retained said bicycle rear wheel hub power transmission drive chain sprockets and said drive chain upon said pawls reaching end of respective inward radial travel, and l) a pedals forward clutching apparatus fitted for actuation of said drive chain and consequent power transmission to said bicycle rear wheel hub power transmission drive sprockets upon a forward pedaling motion and slip upon actuation of said bicycle drive chain driver with said pedals in a predominantly stationary state, Whereby said electronic control system commands said gearmotor of said bicycle drive chain derailer through said servo motor controller to seek and hold said encoder readings corresponding to said derailer shifting positions upon said bicycle speed sensing means relaying said corresponding bicycle speed derailer shifting thresholds are reached with simultaneous lack of necessary actuation of said pedals resulting in said drive chain forward movement sensor relaying corresponding signal to said electronic controls system in turn actuating said chain driver motor forcing rotation of said cam hub, collapse of said pawls, disengagement to said rear wheel drive hub, rotation of said pawl hub and thereto retained said rear wheel hub power transmission drive sprockets, forward movement of said drive chain thereby permitting said rear hub drive chain derailer to conduct necessary said shift operation with following cessation of actuation of said chain driver motor resulting in return of said pawls to said ratchet hub engagement positions, under the action of said compression springs.
