SYSTEM FOR ADJUSTING THE TENSION OF THE WOUND PART OF A BELT DRIVE TRANSMISSION |
摘要 |
<p>The invention proceeds from a system for adjusting the tension of a belt part (for example, a band) of a belt transmission mounted downstream of a vehicle engine. The belt transmission preferably is continuously adjustable with respect to its transmission ratio. A first means is provided for controlling (open loop and/or closed loop) the vehicle engine and a second means is provided for controlling (open loop and/or closed loop) the belt transmission. Here, a first signal is determined by the first means and this signal represents the engine torque of the vehicle engine and this signal is supplied by the first means to the second means. The tension is adjusted by the second means in dependence upon the first signal and a safety reserve. The essence of the invention is that the safety reserve is not fixedly pregiven; instead, it is determined in dependence upon various conditions. In this way, one achieves a reduction of the reserve pressure of the belt tensioning control and thereby reaches a better operating efficiency of the transmission and therefore a reduced fuel consumption.</p> |
