<p>Said transmission use a sprocket (1) integral with the drive wheel (7) that receives movement by means of a chain (2) from a plate (3) fixed to the pedals (4) which are actuated by the user. The plate (3) has variable radii selected in such a way that constant effort T is achieved despite variations in the effort by the user and the geometry of the pedals (4). Said transmission can be additionally equipped with an effort recording device consisting of a disk (5) integral with the drive wheel and fixed to the sprocket by means of a shaft (6) that is sufficiently flexible so that an angular phase shift 'X' between the sprocket (1) and the disk (5) takes place under the effect of effort T.</p> |
