    Abstract: This disc rotor has a hat portion having a cylindrical portion and a sliding plate portion having an insertion hole into which the cylindrical portion is inserted, being connected together with the hat portion in a state in which the cylindrical portion protrudes from the insertion hole. The coupling is achieved by pinching an inner peripheral edge of the sliding plate portion between a first portion and a second portion that are formed in the cylindrical portion. The second portion is formed by plastically deforming an outer peripheral side of the cylindrical portion toward the first portion.

    Abstract: A vehicle wheel may include a rim for receiving a tire and a wheel disk attached to the rim in a cohesive connection, in a force-fitting connection, and/or a form-fitting connection, with an attachment region for releasably attaching to a wheel mount. The wheel disk may be formed of a steel workpiece that is heat-treated at least in certain regions. To provide a utility vehicle wheel vehicle wheel having high operational strength and reliability relative to the prior art, the wheel disk may have at least in a transition region for attaching to the rim a heat-treated structure with at least one of a tensile strength of between 500 and 1300 MPa or a hardness of between 150 and 400 HV 0.1.

    Abstract: A novel method of manufacturing a toothed disc is taught wherein the teeth can be cold formed to a relatively high set of tolerances in a relatively time-efficient manner. A cold-formed disc blank with an annular thickened ring about its periphery is forced through a set of tooth forming rollers which engage the annular thickened ring. As the blank is forced through the set of rollers, the rollers cold forming tooth structures in the annular ring. In some circumstances, the tooth structure can be a final desired tooth profile and in other circumstances, the disc blank may be forced through two or more different sets of tooth forming rollers, each set of tooth forming rollers contributing to the forming of the final, desired tooth profile.

    Abstract translation: 教导了一种制造齿盘的新颖方法，其中齿可以以相对有效的方式冷成形为相对较高的公差集合。 围绕其周边具有环形加厚环的冷成型盘坯被迫通过与环形加厚环接合的一组齿形辊。 当坯料被迫穿过该组辊子时，辊子在环形环中形成齿形结构。 在一些情况下，齿结构可以是最终期望的齿形，并且在其他情况下，盘坯可以被迫通过两组或更多组不同的成形辊，每组齿形成辊有助于形成最终的， 所需齿廓。
