Problems solved by technology

[0005] One problem with motorized bicycle components is that the motor can be overloaded due to failure of cables or other electrical components
Also, the motor may be overloaded due to bicycle components exceeding the adjustment range
If the motor is overloaded, the drive train operating the bicycle components may be damaged due to the frequent sudden stop of the gear train

Embodiment Construction

[0051] start reference Figure 1-3 , the illustrated bicycle 10 has an electronically controlled drive train 12 in accordance with a first embodiment of the present invention, as discussed below. The bicycle 10 basically has a frame 14 and a pair of wheels 15 , the rear wheels being driven by a drive train 12 . The bicycle 10 and its various elements are well known in the prior art, except for the improvements of the drive train 12 of the present invention. Therefore, the bicycle 10 and its various elements will not be discussed or illustrated in detail here, other than those associated with the drive train 12 of the present invention. Also, various conventional bicycle components that will not be detailed and / or discussed herein, such as brakes, auxiliary sprockets, etc., may be used with the present invention.

[0052] As used herein, the terms "forward, rearward, upward, above, downward, below and laterally" refer to those directions of the bicycle in its normal riding po...

Abstract

A motorized bicycle actuator assembly has a motorized actuator unit arranged to operate a bicycle component. The motorized actuator unit has a drive train coupled to a reversible motor, and a position switch device or an overcurrent detecting circuit coupled to the motor to stop rotation of a drive axle 95 of the drive train at first and second stop positions. The bicycle component is coupled to the drive axle to move a movable member between a first and second preset component positions that correspond to the first and second stop positions of the drive axle, respectively. First and second shock absorbing elements are arranged to cushion the drive train when the drive axle moves past the first and second stop positions of the drive axle, respectively.

Description

technical field [0001] This invention relates generally to motorized bicycle actuator assemblies. In particular, the present invention relates to motors and drive trains that protect bicycle elements in the event of a failure that would cause the motor to be powered for longer than necessary. Background technique [0002] Cycling is increasingly becoming a form of mass recreation and a means of transportation. Also, cycling has become a very common competitive sport, both amateur and professional. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving various elements of the bicycle. [0003] In particular, bicycle elements have been motorized in order to improve the performance of the bicycle and ease the handling of the bicycle. For example, the part of a bicycle that has been motorized is the transmission or drive train of the bicycle. As a result, many bicycles have been provided w...
