    • It is an object of the present invention to provide a method for uniformly forming a film on an outer circumferential portion of a metal automotive part by preventing penetration of a coating substance into a portion thereof unnecessary to be coated with paint. The method for producing a columnar or cylindrical metal automotive part whose outer circumferential surface includes a portion to be coated with paint and a portion to be uncoated therewith includes the following processes: (1) a process of providing a convergent nozzle-shaped covering jig which covers an outer circumferential surface of the columnar or cylindrical part at an axial end thereof and covers the portion to be uncoated with the paint, with a gap formed between the covering jig and the outer circumferential surface of the part; (2) a process of discharging a gas from the gap toward an end of a nozzle of the covering jig with the columnar or cylindrical part being rotated; (3) a process of sticking a film-forming substance to the columnar or cylindrical part from an axial side surface thereof.
    • 本发明的一个目的是提供一种通过防止涂层物质渗透到不需要涂覆油漆的部分而在金属汽车部件的外周部分上均匀地形成膜的方法。 用于制造其外周面包括待涂覆涂料部分和未涂覆部分的柱状或圆柱形金属汽车部件的方法包括以下步骤:(1)提供会聚喷嘴形状的覆盖夹具的过程, 在圆柱形或圆柱形部分的轴向端部处覆盖圆柱形或圆柱形部分的外圆周表面,并且在覆盖夹具和部分的外圆周表面之间形成间隙,以覆盖待涂覆涂料的部分; (2)在圆柱状或圆筒状的部件旋转的状态下从间隙朝向覆盖夹具的喷嘴的端部排出气体的工序, (3)将成膜物质从其轴向侧面粘附到柱形或圆柱形部分的过程。

    • In order to attach cup bearings 18 with good precision in portions between circular holes 15 that are formed in joining-arm sections 10 of yokes 7a, 7b of a cross shaft universal joint 6 and the tip-end sections of a shaft section 17a of a cross shaft 8 regardless of variation in the dimensions of the joining-arm sections 10, the circular holes 15 in the tip-end sections thereof, and the cup bearings 18, and elastic deformation of the joining-arm sections 10 of the yoke 7a during press-fitting work, press-fitting punches 33 are used to pressure fit the cup bearings 18 to a preset reference position inside the circular holes 15, and the value of the pressure that is applied to the press-fitting punches at that instant is set as a reference pressure, and at the instant when the pressure applied to the press-fitting punches becomes larger than the reference pressure by a preset specified value, the cup bearings 18 are determined to have reached positions where press-fitting is complete.

    • The invention relates to a motor vehicle steering system comprising a steering spindle having several spindle components (1, 2) that are connected to one another in a rotationally fixed manner. One end (11) of a spindle component (1) has a spline shaft profile (12) oriented in an axial direction on the outer periphery, and is therewith inserted into a sleeve-shaped intermediate piece (21), which in the longitudinal direction of the steering spindle is arranged on the other adjacent spindle component (2), and which on the inner periphery has a spline shaft profile (12) that is form-negative with respect to the spline shaft profile (12) of the spindle component (1) such that the spindle component (1) is plug-connected with the intermediate piece (21). In order that two steering spindle components (1, 2), in particular a spindle component (1) on the motor-compartment side, and the subsequent steering coupling (2) can be connected to one another with little effort even with optical inaccessibility, a circumferential guide contour (13) pointing toward the intermediate piece (21) is formed on the spindle component (1), according to the invention, which guide contour is located upstream of the spline shaft profile (12) toward the intermediate piece (21), and which is perforated by grooves (6) of the spline shaft profile (12) thus forming convex guide segments (10).
    • 公开了一种机动车转向系统。 该系统包括由彼此不可旋转地连接的主轴构件组成的转向主轴。 心轴构件的一端具有花键轴轮廓并且被引入到布置在另一个心轴构件上的套筒状中间件中,并且在内周上具有相对于花键轴的负形花键轴轮廓 使得心轴构件插入到中间件。 为了使主轴构件能够以极小的力量彼此连接,即使在视觉上不可接近的情况下,在主轴构件上形成指向中间件的周向引导轮廓。 引导轮廓在花键轴轮廓的上游朝向中间件,并且通过花键轴轮廓的凹槽穿孔以形成凸形引导段。
