  • Method and device for measuring the chain force in a bicycle
    Patent number: 7814800
    Abstract: A method is described for measuring the chain force (FK) in a drive chain (26) engaging on a body (20) that is rotatable around an axle (21) which is fixed in a frame (10) at least two connecting points (22, 23). The method comprises the steps of: measuring the reaction force (FL) between axle (21) and frame (10) at a first connecting point (22); measuring the reaction force (FL) between axle (21) and frame (10) at a second connecting point (23); and adding the two measured reaction forces (FL; FR).

  • Continuously variable transmission including optimizing electric motor
    Patent number: 5951421
    Abstract: A continuously variable transmission provided with a variator for adjusting the transmission ratio of the transmission and one or more hydraulic circuits for lubrication, cooling and transmission control, one or more pumps being installed for the hydraulic circuit. The transmission comprises at least one electric motor to give the transmission better sizing and an improved efficiency.

  • Continuously variable transmission
    Patent number: 5885186
    Abstract: The invention relates to a continuously variable transmission. The continuously variable transmission according to the invention is designed such that in operating conditions to be defined in more detail the transmission ratio is kept essentially constant, in particular for travelling through bends, on inclines, in case of an emergency stop and during a transmission overspeeding. The constant transmission ratio is obtained while the input r.p.m. of the transmission is changing.
