发明名称 DEVICE AND METHOD FOR ADJUSTING THE RATIO OF TRANSMISSION IN A CVT
摘要 PCT No. PCT/DE98/01756 Sec. 371 Date Apr. 2, 1999 Sec. 102(e) Date Apr. 2, 1999 PCT Filed Jun. 26, 1998 PCT Pub. No. WO99/07572 PCT Pub. Date Feb. 18, 1999The invention proceeds from an arrangement or a method for adjusting the transmission ratio of a continuously variable belt transmission having a drive end and an output end. The drive end and the output end have at least one axially displaceable element which has essentially the form of a conical disc. Via sensor means, an rpm signal is detected, which represents the rotational movement of the drive end or the output end, and, on the other hand, a displacement signal is detected which represents the axial displacement of at least one of the axially displaceable elements. The essence of the invention is that means for adjusting the transmission ratio are provided with the aid of which the adjustment takes place at least in dependence upon the detected displacement signal. An advantage of the invention is that, in this way, the possibility is provided to save one rpm sensor. Furthermore, and as shown in the course of the description in greater detail, the total transmission ratio adjustment is substantially independent of the engine load or of the drive torque acting in the drive train.
