Method for determining the rotational speed of the main shaft of a transmission, and transmission comprising a device for detecting rotational speed
Abstract:
The present invention relates to a method for determining the rotational speed of the main shaft (3) of a transmission in which the main shaft (3) is connected to an output shaft (4) via a shiftable planetary gear (17), whereby the main shaft (3) is connected in a rotationally fixed manner to the sun gear (18) and the output shaft (4) is connected in a rotationally fixed manner to the planet carrier (20). The steps of the method are picking up the rotational speed (nHohlrad) of the ring gear (22), picking up the rotational speed (nAbtrieb) of the output shaft or the planet carrier (20), and computing the rotational speed (nHauptwelle) of the main shaft (3) from the rotational speed (nHohlrad) of the ring gear and the rotational speed (nAbtrieb) of the output shaft or the planet carrier (20). The present invention further relates to a transmission having a rotational speed pickup device.
Abstract(Chinese):

本发明涉及一种用于确定主轴（3）通过可移动行星齿轮（17）连接到输出轴（4）的变速器的主轴（3）的转速的方法，由此， 主轴（3）以旋转固定的方式连接到太阳齿轮（18），并且输出轴（4）以旋转固定的方式连接到行星架（20）。 该方法的步骤是拾取环形齿轮（22）的旋转速度（nHohlrad），拾取输出轴或行星架（20）的转速（nAbtrieb），并计算旋转速度（nHauptwelle） 从主轴（3）的旋转速度（nHohlrad）和输出轴或行星架（20）的转速（nAbtrieb）。 本发明还涉及具有转速拾取装置的变速器。
