摘要： The propeller shaft arrangement which connects a transmission with a differential gear of a vehicle includes a first propeller shaft segment connected to the transmission at one end thereof and a second propeller shaft segment connected to the differential gear at one end thereof. The first and second propeller shaft segments are made of aluminum. The other end of the second propeller shaft segment is connected with one end of a steel center bearing via art universal joint. Serrations are formed at the other end of the center bearing and at the other end of the first propeller shaft segment such that the serrations of the center bearing are engaged with those of the first propeller shaft segment and a locking nut is screwed down over the engaging serrations to join the first propeller shaft segment with the center bearing. Since the center bearing is made of steel whereas most of the propeller shaft is made of aluminum, the weight of the propeller shaft is reduced while ensuring sufficient strength of the center bearing. Further, the first propeller shaft segment is connected with the center bearing by the serrations and the locking nut. Therefore, welding the aluminum shaft with the steel bearing, which is technically difficult to perform, is not necessary.

摘要翻译： 将变速器与车辆的差速齿轮连接的传动轴配置包括在其一端连接到变速器的第一传动轴段和在其一端连接到差动齿轮的第二传动轴段。 第一和第二传动轴段由铝制成。 第二传动轴段的另一端通过万向接头与钢中心轴承的一端连接。 在中心轴承的另一端和第一螺旋桨轴段的另一端处形成有锯齿，使得中心轴承的锯齿与第一传动轴部分的锯齿接合，并且将锁定螺母拧到接合部 将第一个螺旋桨轴段与中心轴承连接起来。 由于中心轴承由钢制成，而大多数传动轴由铝制成，所以在确保中心轴承的强度的同时减小了传动轴的重量。 此外，第一传动轴段通过锯齿和锁紧螺母与中心轴承连接。 因此，在技术上难以执行的钢轴承焊接铝轴是不必要的。
