    Abstract: A drive shaft with an endless-fiber-reinforced plastic tube made of a thermosetting plastic matrix material and with a joint-connecting body that is connected nonrotatably with a plastic tube by means of a pin inserted into the plastic tube. The drive shaft is intended to be capable of being manufactured universally in large quantities efficiently and in different lengths for use, and can also handle severe loads mechanically even at high operating temperatures. For this purpose, an internal layer with axially aligned fibers or fiber strands, preferably made of carbon, is provided in the plastic tube, on which at least one double layer with fibers arranged inclined symmetrically to the axial direction is applied. The plastic tube is provided internally with axially aligned profiling that remains constant over the entire length of the plastic tube and is formed of the matrix material, in the manner of a spline bore. The pin, provided on its outer circumference with a negatively shaped matching opposite profile, engages positively by a sliding fit or gentle press fit in the internal profile of the plastic tube. The pin is also secured in the plastic tube in the axial direction by gluing or by a locking connection using a snap ring.

    Abstract translation: 一种驱动轴,其具有由热固性塑料基体材料制成的环形纤维增强塑料管,并具有通过插入塑料管中的销不可旋转地与塑料管连接的接头连接体。 驱动轴旨在能够以大量有效且不同长度的方式普遍制造,并且也可以在高工作温度下机械地处理严重的负载。 为此目的,在塑料管中提供具有轴向排列的纤维或纤维股的内层,优选由碳制成,其上施加至少一个具有相对于轴向对称布置的纤维的双层。 塑料管内部设置有轴向对齐的轮廓,其在塑料管的整个长度上保持恒定,并且以花键孔的方式由基质材料形成。 在其外圆周上具有负形状的匹配相对轮廓的销通过滑动配合或温和压配合在塑料管的内部轮廓中而接合。 销还通过胶合或通过使用卡环的锁定连接件在轴向方向上固定在塑料管中。
