  • Method for determining the rotational speed of a part, ascertaining the slipping of a continuously variable transmission (CVT), and for controlling a CVT, and a conical disc flexible drive transmission
    Patent number: 7603893
    Abstract: The input rotational speed of a belt-driven conical-pulley transmission is determined by measuring a wheel rotational speed and the transmission ratio and by calculating the input rotational speed therefrom. In order to ascertain the slipping of a CVT transmission, the rate of change in the transmission ratio is drawn upon, or an acoustic parameter of the transmission is used. In the fluid control system, a valve is used whose opening cross-section is controlled according to the one differential pressure. In order to oil the conical discs, injection holes of an injection tube are used that passes through a slot provided in a slide rail resting against a strand of a flexible torque transmitting member of a conical disc flexible drive.

  • Method for determining the rotational speed of a part, ascertaining the slipping of a continuously variable transmission (cvt), and for controlling a cvt, and a conical disc flexible drive transmission
    Publication number: 20050277500
    Abstract: The initial rotational speed of a conical disc flexible drive transmission is determined by measuring a wheel rotational speed and the gear ratio and by calculating the initial rotational speed therefrom. In order to ascertain the slipping of a CVT transmission, the rate of change in the ratio is drawn upon or an acoustic parameter of the transmission is used. In the fluid control system, a valve is used whose opening cross-section is controlled according to the one differential pressure. In order to oil the conical discs, injection holes of a injection tube are used that passes through a slot provided in a slide rail resting against a side of a flexible drive means of a conical disc flexible drive means.
