摘要： A composite push-pull bar for use in a rail vehicle includes end-side connecting elements for axial introduction of compressive and tractive forces; and a rod-shaped structural element disposed between the end-side connecting elements for take-up and transmission of compressive and tractive forces. The rod-shaped element comprises a longitudinally extending core, a prestressed composite winding, including a defined number of wrappings of one or several reinforcing fibers embedded in a cured matrix material, applied in a longitudinal direction of the core so as to leave opposite longitudinal sides of the core not covered by the winding, the winding extending over the connecting elements and two skins arranged on the opposite longitudinal sides of the core not covered by the winding to form a sandwich structure with the core and which remain rigid under compression in their longitudinal direction.

摘要： A process for joining components and assembly units of rail-borne vehicles by bonding is described, in which the use of an adhesive, which produces fatigue strength but cures more slowly, is combined with the use of an adhesive that ensures sufficient strength for handling in a short time, wherein complicated design of the bonded joints as well as the need for a large amount of devices are to be avoided, manufacturing tolerances are to be equalized, and defined minimum bonded gap widths are to be maintained. Furthermore, the wetting by the adhesive shall be limited to selected joining surfaces, without having to remove and dispose of the edge limitation. This object is accomplished by applying a quick-bonding first adhesive layer having an intrinsic dimensional stability to first joining surfaces and a more slowly curing second adhesive layer to second joining surfaces and by joining the components before or after the application of the second adhesive layer, wherein the first adhesive layer rapidly ensures sufficient strength for handling and maintains a predetermining joining space, while the second adhesive layer fills out the joining space set and ensures fatigue strength after its curing. The adhesive used for the first adhesive layer is also used as a permanent edge limitation.

摘要翻译： 描述了通过粘合来连接轨道车辆的部件和组装单元的方法，其中使用产生疲劳强度但更慢地固化的粘合剂与使用确保足够的强度用于处理的粘合剂相结合 短时间内，要避免接合接头的复杂设计以及大量器件的需要，制造公差要相等，并且要保持限定的最小接合间隙宽度。 此外，粘合剂的润湿应限于选定的接合表面，而不必去除和处理边缘限制。 该目的是通过将施加具有固有尺寸稳定性的快速粘合第一粘合剂层施加到第二接合表面上，并且将更缓慢固化的第二粘合剂层施加到第二接合表面并且通过在施加第二粘合剂层之前或之后接合部件来实现， 其中第一粘合剂层快速确保足够的强度用于处理并保持预定的接合空间，而第二粘合剂层填充接合空间组合并确保其固化后的疲劳强度。 用于第一粘合剂层的粘合剂也用作永久边缘限制。
