    • A screw bar for connecting a nut member and a bearing member of a pantograph-type jack includes a cylindrical-shaped bar member having a joint portion formed integrally with the bar member at one end and a threaded portion formed integrally on the bar member at the other end. The nut member of the jack is threadably engageable with the threaded portion of the screw bar, and the bearing member of the jack is pivotally mountable on the bearing support portion of the screw bar. The maximum outer diameter of the threaded portion is less than or equal to the desired diameter of the bearing support portion so that the bearing member can be mounted on the screw bar from the threaded-portion end. Preferably, the joint portion includes a flange portion having an outer diameter greater then the desired diameter and the bearing support portion is provided with a lug portion. The lug portion and the joint portion are positioned on opposite sides of the bearing member mounted on the bearing support portion to prevent axial movement of the bearing member. A method for forming the screw bar also is disclosed.
    • 用于将螺母构件和缩放式千斤顶的轴承构件连接的螺杆包括:圆柱形的杆构件,其具有在一端与杆构件一体形成的接合部和在该杆构件上一体形成的螺纹部 另一端 千斤顶的螺母构件可螺纹地与螺杆的螺纹部分接合,并且千斤顶的轴承构件可枢转地安装在螺杆的轴承支撑部分上。 螺纹部分的最大外径小于或等于轴承支撑部分的期望直径,使得轴承构件可以从螺纹部分端部安装在螺杆上。 优选地,接头部分包括具有大于期望直径的外径的凸缘部分,并且轴承支撑部分设置有凸耳部分。 凸耳部分和接头部分位于安装在轴承支撑部分上的轴承部件的相对侧上,以防止轴承部件的轴向移动。 公开了一种用于形成螺杆的方法。

    • A retractable headlamp assembly for automobiles in which a headlamp, pivotally mounted on the automobile frame, is operatively coupled to the rotatable shaft of a motor by a link mechanism. The motor, operating through the link mechanism, is energizable to cause the headlamp to be moved angularly between a first position at which the headlamp projects out of the front hood of the automobile, and a second position at which the headlamp is retracted within the front hood. An adjustable stop is provided to stop the headlamp at the first position, which adjustable stop is adjusted to bring the first position into conformity with an angularly displaced position of the rotatable motor shaft, which is displaced through a slip angle from a normal stopping position. Such an arrangement assures that the headlamp can be stopped at a fixed position at all times for emitting a correctly directed beam of light irrespective of the varying positions at which the motor can stop.
    • 一种用于汽车的可伸缩头灯组件,其中枢转地安装在汽车框架上的头灯通过连杆机构可操作地联接到电动机的可旋转轴。 通过连杆机构操作的电动机是可激励的,以使头灯在前照灯从汽车前罩引出的第一位置和前照灯在前方的后退中的第二位置之间成角度地移动 罩。 提供可调节止动件以在第一位置处停止前照灯,该可调节止动件被调节以使第一位置与从正常停止位置移动一个滑移角度的可旋转电动机轴的角位移位置一致。 这样的布置确保了头灯可以始终停在固定位置,以便发射正确定向的光束,而与马达可以停止的变化位置无关。
