摘要： The device for transmitting pedalling movement in cycles for translocation or training of the type comprising an elliptical chainring with a central part which accepts a deformable elastomeric material, a circular chainring at the rear with freewheel and transmission belt, is characterized in that the elliptical chainring (10) is designed with an internal arrangement within its thickness and width with the configuration of several modules (11) of triangular configuration, each module having two arms (11a), (11b) connected by a connecting part (11c), and each arm (11a) being arranged with a hollowed-out configuration (11d) forming a seat for a component (12) made of elastomeric material, and in that between two successive modules (11) is defined a space (e) for positioning a component (13) of spider-shaped configuration with a number of arms (13a) that is equal to the number of spaces formed between the modules, and in that the arms (13a) of said component are arranged with a hollow forming a seat (13c) and, on the opposite side, a rib-forming projection (13d) that contributes to immobilizing the elastomeric blocks (12), and in that outer (14) and inner (15) end plates are attached one on either side of the elliptical chainring (10) allowing the insertion of connecting means (16) and of the pedal crank (17) and bottom bracket axle (18).

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).
