用于商用车辆的轴联动装置以及用于制造该轴联动装置的方法
摘要：
本发明涉及一种用于商用车辆的轴联动装置，该轴联动装置包括由金属材料制成的轴(2；102)，以及还包括至少一个由金属材料制成的纵向传动杆(8；103、104)，纵向传动杆设有连接区段(9；118)，该连接区段设有接纳部(9a；112)，轴(2；102)通过中空的联轴节(4；110)这样设置在接纳部中，即，使轴(2；102)和纵向传动杆(8；103、104)抗扭地相互连接。在本发明的轴联动装置中，构成纵向传动杆的连接区段和构成轴的联轴节的金属材料的特征这样相互限定的，即，使连接区段的E-模量小于联轴节的E-模量，和/或连接区段的断裂强度大于联轴节的断裂强度，和/或纵向传动杆的连接区段的金属材料的屈服极限ReS或在该金属材料不具有显著的屈服极限情况下的延伸强度RP0.2高于轴的由纵向传动杆包围的联轴节的金属材料的屈服极限ReS或延伸强度RP0.2。
摘要（英）：

The invention relates to an axle assembly for a commercial vehicle, having an axle (2; 102) manufactured from a metal material and having at least one trailing arm (8; 103, 104) manufactured from a metal material, said trailing arm comprising a connection section (9; 118) having a receptacle (9a; 112), in which the axle (2; 102) with a hollow coupling section (4; 110) is seated such that the axle(2; 102) and the trailing arm (8; 103, 104) are connected to one another rotationally fixed. In the axle assembly, the properties of the metal materials of the connection section of the trailing arm and of the coupling section of the axle are adapted to one another such that the modulus of elasticity of the connection section is less than the modulus of elasticity of the coupling section and/or the breaking strength of the connection section is greater than the breaking strength of the coupling section, and/or the yield point Res or - if the metal material does not have a pronounced yield point - the elongation limit Rpo,2 of the connection section of the trailing arm is higher than the yield point Res or elongation limit Rpo,2 of the metal material of the coupling section of the axis which the connection section encloses.
