    • A method to manufacture a steel die having a Physical Vapor Deposition wear resistant coating on a profile surface and a steel die formed thereby is disclosed. The steel die is subjected to quenching and tempering to achieve a Rockwell hardness in the range of about 40-45 Rc and then subjected to machining to form a profile surface. The surface is then subjected to Physical Vapor Deposition of a wear resistant coating that may be multiple layers of CrN, AlCrN, TiCrN, TiN, TiCN or TiAlN, and preferably is alternating layers of TiN—TiCN—TiN. The coating is applied at a sufficient thickness to impart wear resistance to the steel die. The steel dies are useful in sheet metal stamping operations.
    • 公开了一种在轮廓表面上制造具有物理气相沉积耐磨涂层的钢模的方法和由此形成的钢模。 对钢模进行淬火和回火以获得在约40-45℃范围内的洛氏硬度,然后进行加工以形成轮廓表面。 然后将该表面进行可以是多层CrN,AlCrN,TiCrN,TiN,TiCN或TiAlN的耐磨涂层的物理气相沉积,并且优选是TiN-TiCN-TiN的交替层。 以足够的厚度施加涂层以赋予钢模具耐磨性。 钢模具可用于钣金冲压操作。

    • A steering linkage assembly for a motor vehicle has a tie rod and a drag link connected to a steering knuckle in an over/under arrangement, with first and second ball joints for the drag link and the tie rod respectively on opposite sides of the steering knuckle and having a common axis that is located within an interior volume of a wheel supported by the steering knuckle. The coaxial, over/under configuration results in a ball joint assembly having a minimum axial dimension so that both ball joints can be located inside the inner rim of the wheel and as far outboard and as far forward as possible. The extreme outboard placement of the drag link ball joint maximizes the length of the drag link to reduce bump and roll steer sensitivity, and the forward placement maximizes the effective steering arm radius to reduce steering linkage loads while also improving packaging.
    • 用于机动车辆的转向连杆组件具有连杆和牵引连杆,其以过/下排列方式连接到转向节,其中分别在转向节的相对侧上的牵引连杆和拉杆的第一和第二球接头 并且具有位于由转向节支撑的车轮的内部体积内的公共轴线。 同轴的上/下配置导致具有最小轴向尺寸的球接头组件,使得两个球接头可以位于车轮的内轮缘内部并且尽可能远地向外侧并且尽可能远。 拖曳链节球接头的极端外侧放置使拖曳链节的长度最大化,以减小碰撞和滚动转向灵敏度,并且前进位置使有效的转向臂半径最大化,以减少转向连杆负载,同时也改善包装。
