Embodiment Construction

[0066] Referring first to FIG. 1 , FIG. 1 shows the rear of a vehicle, ie, a bicycle 10 . Although described here in a manner particularly suitable for non-motorized vehicles, and bicycles in particular, the vehicle may be of another type including, for example: motorized bicycles, motorcycles, automobiles, trucks, tanks, and the like. In addition, the transmission according to the present invention is not limited to use in vehicles, but it can be used in conjunction with other mechanisms. These mechanisms can be lifts, turbines, electric vehicles, jacks, pulleys, winches, etc.

[0067] Only those parts of the bicycle 10 that are relevant to the present invention will be described below, all other components of the bicycle 10 may be completely standard. Thus, the bicycle 10 includes a rear wheel 12 having spokes 14 and a sprocket 16 associated therewith.

[0068] For clarity, unless otherwise stated, rotation of the rotatable member is relative to forward (ie, right to left ...

Abstract

An internal mechanical automatic transmission assembly for discrete shifting of transmission ratios for forward travel, comprising a plurality of interconnectable transmission ratio producing units constituted by PTCs arranged side by side and being concatenatingly engageable and disengageable one to the adjacent in relation to a rotational speed resulting from a torque input to the transmission assembly, each of the PTCs being designed to affect a transmission ratio to thereby produce an overall transmission ratio over the transmission assembly. The transmission according to the present invention may further comprise one or more multiplication assembly.

Description

technical field [0001] The present invention relates to automatic transmissions, particularly those that are mechanical and internally mounted. The transmission will be described below primarily in connection with its use in a bicycle, but it should be understood that the transmission of the present invention has many applications and can be used mutatis mutandis in connection with various vehicles, implements and machines. Background technique [0002] Many systems exist for shifting between bicycle gears to affect different gear ratios so that the rider can adjust the system to a desired gear for a comfortable ride. For example, a cyclist may desire a lower gear (gear ratio) when climbing a steep hill, or a higher gear in anticipation of going fast. [0003] There are a number of shifting systems that require external power (usually electric and use batteries), some are purely mechanical, some are externally positioned (exposed to the surrounding environment), some are in...
