    • The invention relates to a mobile working machine, particularly an automatic concrete pump, having a chassis (10) designed as a tractor-trailer. The tractor-trailer comprises a tractor (12) and a multi-axle semi-trailer (14) supporting the working machine and connected to the tractor by means of a fifth wheel (16). A support construction (38) that can be supported on a surface (40) is located in the area of the semi-trailer (14). The support construction (38) comprises two front stabilizers (42′, 42′) and two rearward stabilizers (44), each pivotable between a transport position and at least one support position relative to the semi-trailer. Means for raising and securing the tractor (12) are further disposed on the semi-trailer (14), so that the tractor (12) forms a ballast weight for stabilizing the semi-trailer supported by the support construction (38) on the base (40) in the support position. According to the invention, the bearing points (48′, 48) of the front stabilizers (42′, 42′) comprise a hollow space (80) through the center of the axis, and the means for raising and securing the tractor disposed on the semi-trailer (14) each comprise a lift member (82) extending through the central hollow area (80) of the bearing point (48, 48) from top to bottom and releasably attachable to the tractor (12).
    • 本发明涉及一种移动式工作机,特别是一种具有设计为拖拉机 - 拖车的底盘(10)的自动混凝土泵。 拖拉机拖车包括拖拉机(12)和支撑工作机器的多轴半挂车(14),并通过第五轮(16)连接到拖拉机。 可以支撑在表面(40)上的支撑结构(38)位于半挂车(14)的区域中。 支撑结构(38)包括两个前稳定器(42',42')和两个向后稳定器(44),每个后稳定器(44)可在运输位置和相对于半拖车的至少一个支撑位置之间枢转。 拖拉机(12)的升起和固定装置还设置在半挂车(14)上,使得拖拉机(12)形成用于使由底座(38)支撑的半挂车稳定的压载重物 (40)处于支撑位置。 根据本发明,前稳定器(42',42')的支承点(48',48')包括穿过轴心的中心的中空空间(80),并且用于升高和固定设置在 半挂车(14)各自包括从顶部到底部延伸穿过轴承点(48,48)的中心空心区域(80)的提升构件(82),并且可释放地附接到拖拉机(12)。

    • A stable and play-free pivot connection of a bicycle derailleur between a parallelogram link and either a base member or a chain cage. The pivot points are formed with first and second bushings that are arranged as far from one another as possible. The parts are connected by pivot pins having a anti-rotation contour for preventing rotation of the pin within an inner pivot part. The axial displacement of the pivot pin is prevented by a securing element or by a deforming element engaging a holding contour on the pivot pin. One of the first and second bushings is protected and arranged in a blind hole and the other of the first and second bushings is covered on the outside by a pin head of the pivot pin.
    • 平行四边形连杆与底座或链条架之间的自行车拨链器的稳定且无间隙的枢转连接。 枢转点形成为尽可能远离彼此布置的第一和第二衬套。 这些部件通过具有防旋转轮廓的枢轴销连接,以防止销在内枢转部分内旋转。 枢轴销的轴向位移由固定元件或与枢轴销上的保持轮廓接合的变形元件来防止。 第一和第二衬套中的一个被保护并布置在盲孔中,并且第一和第二衬套中的另一个通过枢轴销的销头在外部被覆盖。
