摘要： The invention relates to a wear protection element, in particular a boss with a bearing part, which bears a hard material element in or on a mounting, wherein the hard material element is indirectly or directly supported by a bottom supporting surface of a securing portion on an opposing surface of the bearing part. In the case of such a wear protection element, the service life can be optimized by indirectly or directly connecting to the securing portion a transitional portion, which tapers the outer contour of the hard material element, at least over a certain region, in the direction of its end that is remote from the supporting surface.

摘要： The invention relates to a fastening system for add-on parts on vehicles that allows add-on parts (5) on vehicles (1) to be easily installed and removed. The invention further relates to a vehicle (1) provided with such a fastening system. The fastening system comprises a connection part (2), which lies against the vehicle (1), and a base (3), which is connected to the add-on part (5). The connection part (2) is designed as a profiled element, the outer surface (2h) of the exterior of which corresponds at least in some sections to the outer surface of a prism having the base of a regular polygon having at least one interior angle deviating from 90°. The base (3) comprises a trapezoidal groove (3a) having leg surfaces (3d, 3e) that are arranged at an angle from each other and that are connected to each other by a base surface (3f). The two leg surfaces (3d, 3e) lie flush against two lateral surfaces (2d, 2e) of the connection part (2) that are not directly adjacent to each other. A hole (3b) extends through the base (3) symmetrically with respect to the groove (3a) and centrally through the base surface (3f). The connection part (2) has a receptacle (2g), in which a connecting element (4) engages, wherein said connecting element is inserted through an opening (3b) in the base (3).

摘要： Provided is a bolt (1) for projection welding in which a portion of large fusion depth is formed in a small region and in which junction to a steel sheet part is secured in other regions, thereby realizing high weld strength and stable junction state. A bolt (1) includes a shaft part (2), an enlarged diameter part (3), and a fusion bonding projection (4), the fusion bonding projection (4) includes an initial fusion part (4A) having at an end surface thereof a tapered portion (15) and a main fusion part (4B) continuous with the initial fusion part (4A). Energization with welding current for fusing the fusion bonding projection (4) only is effected on the fusion bonding projection (4), and in which through pressurization of the fusion bonding projection (4) against a steel sheet part and subsequent energization thereof, a region of the fusion bonding projection (4) is fusion-bonded to the steel sheet part, and an end surface (6) of the enlarged diameter part (3) on the outer peripheral side thereof is brought into junction with a surface of the steel sheet part. With this structure, it is possible to realize a satisfactory welding in an appropriate fused state.
