摘要： The non-circular front chain wheel for crank gear is comprised of a crank gear wheel (1) allowing to increase progressively the cycling torque from the dead point up to the point where the extension of the leg allows to create the maximum effort, due to a progressive variation of the primitive radius of the toothing between these two points, followed by a rapid decrease to the next dead point. The principle is that the force to be provided is proportional to the muscular force that the user may provide. It essentially concerns the cycle industry but may also find applications in other fields, for example physical exercisers for body-building or reeducation, and in general all apparatuses utilizing the cycling motion and a chain or belt transmission system between the front wheel or wheels of the crank gear and one or a plurality of pinions actuating the device to be driven.

摘要： The invention relates to a device for transmitting a pedalling movement on cycles used for travel or training. The invention is characterised in that: the device combines an elliptical chainring (1) at the front of the cycle which is connected to the crankset (2) by means of a front free wheel (4), a rear chainring (6) also comprising a free wheel (7) and a transmission belt (5); the device is arranged to enable the automatic levelling of the front elliptical chainring in the horizontal and, consequently, equilibrium position when the user stops pedalling; and the connection and the drive system between the chainrings (1 and 6) is provided by an elastically-deformable and -extendible belt (5).

摘要： A chain wheel for a bicycle includes an oblong gear (1) having a flat shape. The oblong gear has a central point (11) and has a periphery (12) having two opposite relatively shortest points (13) and two opposite relatively longest points (14). The periphery of the oblong gear has a tooth number equal to that of a circular gear. The oblong gear is driven by two pedals (2) to drive and rotate a chain (20). Thus, the moment produced by the oblong gear has different values to compensate the different positions of the two pedals, so that the rider's legs can apply a pedaling force on the two pedals evenly and smoothly, thereby facilitating the rider pedaling the two pedals.
