摘要： Vehicle propelled by muscle power, in particular scooter, with at least one driving wheel and at least one tread surface (5, 5’) which is movable via a tread surface stroke, wherein the force transmission from the at least one tread surface (5, 5’) to the at least one driving wheel takes place by means of a driving element (6, 6’) which is guided with a nonpositive or positive fit via a drive shaft (8, 8’) which is coupled to the driving wheel via a freewheeling mechanism, wherein the drive shaft (8, 8’) and/or preferably at least one deflecting roller (7, 7’) is/are divided into at least two axial regions (7b, 7c; 7b’, 7c’, 8a, 8b; 8a’; 8b’) with radii which differ from one another or are variable, and the driving element (6, 6’) is divided into partial sections with different cross sections which are designed in such a manner that the partial sections (6a, 6b 6c; 6a’, 6b’ 6c’) of the driving element (6, 6’) are guided within the tread surface stroke (O-U) on the respectively corresponding axial region of the drive shaft (8, 8’’) and/or deflecting roller (7, 7’). As a result, the overall transmission ratio (uges) of the vehicle can be configured within the tread surface stroke (O-U) within wide limits, wherein, in particular, the drive shaft (8, 8’) which is designed according to the invention can undertake a plurality of revolutions without colliding with a driving element.

摘要： A gear assembly includes a ring gear (1) mounted to a body (2) and a pawl (24) biased by a spring is engaged with ratchet teeth in the inner periphery of the ring gear (1). A control lever (25) is fixed to an end of the pawl (24) by a link (243) so as to disengage the pawl (24) from the ratchet teeth by rotating the control lever (25). A shaft (31) extends through the body and is fixed to a driving gear (6). The ring gear is connected with a wheel of the transportation tool. A coil spring (4) is connected between the shaft (3) and the body (2) to provide a force to return the body (2). The driving gear (6) is driven by a transmission device of the transportation tool and the driving gear drives the ring gear to rotate the wheel forward. The wheel can be rotated backward by operation of the control lever to disengage the pawl from the ratchet teeth.

摘要： A pedal lever type bicycle includes a pedal lever having a front portion and a rear portion, with an intermediate pivot point located substantially above the center of the rear wheel, and to the rear of the front of the rear wheel. The rear portion of the pedal lever has dog-leg configuration with a slider that is attached to a drive chain. The slider is mounted on a straight section of the rear portion of the pedal lever which extends slightly above and to the rear of the rear wheel hub, so that the chain exerts a force to move the slider outwardly on the rear portion of the pedal lever when it is in a lower position, and in the opposite direction when it is raised. Changes of mechanical advantage of 3 or 4 to 1 are available with this configuration of the pedal lever. The bicycle incorporates positive intuitive gear controls and quick release mechanisms for all major components of the propulsion system.

摘要： The invention concerns a transmission device for bicycles and the like of the type wherein a toothed chain-wheel, driven by the user, transmits the movement to the wheel (1) via a sprocket (13), with an interposed free-wheel device (18). The invention is characterized in that the toothed chain-wheel (4) is mounted on the shaft (2) of the wheel (1) and drives a sprocket (14) on the shaft of which is keyed a second sprocket (15) driving the sprocket (13) of the wheel via planetary gear wheels. The toothed chain-wheel (4) is driven with an interposed free-wheel device, by a sprocket (6) meshing with a toothed sector located at the end of an arm articulated on the machine through its other free end and extending beyond its pivot pin into a lever on the free end of which the user acts.
