    • A gearbox, in particular for motor vehicles, has an input shaft and an output shaft, as well as a first torque-transmitting device which is arranged between input and output shafts, makes possible various transmission ratios and, in one mode of operation, totally interrupts force transmission from the input shaft to the output shaft. The object of the invention is to provide a cost-effective gearbox with an automatic mode which can transmit high torques and avoid a total load interruption during gear shifts or changes in transmission ratio. This object is attained in the above-mentioned gearbox in that a second torque-transmitting device is arranged parallel to the first device between input and output shafts and transmits, unlike the first device, a selectable torque which is continuously variable from near zero to its maximum possible value.
    • 特别是用于机动车辆的变速箱具有输入轴和输出轴以及布置在输入和输出轴之间的第一扭矩传递装置,使各种传动比成为可能,并且在一种操作模式下 中断从输入轴传递到输出轴的力。 本发明的目的是提供一种具有自动模式的具有成本效益的齿轮箱,该变速箱可以传递高转矩,并避免在换档期间的总负载中断或传动比的变化。 该目的在上述齿轮箱中实现,其中第二扭矩传递装置在输入和输出轴之间平行于第一装置布置,并且与第一装置不同,并且与从第零装置连续变化的可选扭矩传递 最大可能值。

    • A locking device for a tool with telescopically displaceable parts such as the various tools including a drilling jar used in the deep-well drilling art comprises thickened spindle portion (1) and a sleeve portion (2) with a displaceable sleeve (11) displaceable therein to and away from an axial abutment (17). The thickening of the spindle portion provided by a rigid tapered sleeve (3) with tapered end surfaces (5 and 6) and the sleeve (11) within the sleeve portion with an internal tapered surface (12) are coupled via locking balls (19) disposed for radial movement in an annular cage 20 between the rigid and displaceable sleeves 3 and 11. The sleeve (11) is held by an axial spring (16) in such a position that the balls come to lie axially between the axial abutment (17) and a region of the tapered sleeve (3) having a larger diameter and thereby form a constriction to the passage of the sleeve (3) of the spindle portion ( 11). This constriction can only be passed when the spindle and tapered sleeve (3) is pulled axially with an overload force sufficient to impress a radial force on the balls (19) which in turn forces an axial displacement of the internal tapered sleeve (11) disposed in the sleeve portion until the balls move radially sufficiently to allow passage of the larger diameter of the sleeve (3) and spindle to pass.
    • 用于具有可伸缩部件的工具的锁定装置,例如包括在深井钻井技术中使用的钻孔罐的各种工具,包括增厚的主轴部分(1)和具有在其中可移位的可移位套筒(11)的套筒部分(2) 远离轴向支座(17)。 由具有锥形端面(5和6)的刚性锥形套筒(3)提供的主轴部分的增厚和具有内部锥形表面(12)的套筒部分内的套筒(11)通过锁定球(19)联接, 设置成在刚性和可移动的套筒3和11之间的环形保持架20中径向移动。套筒(11)由轴向弹簧(16)保持在这样的位置,使得球轴向地位于轴向支座(17) )和锥形套筒(3)的具有较大直径的区域,从而形成与主轴部分(11)的套筒(3)的通道的收缩。 当主轴和锥形套筒(3)以足以在球体(19)上施加径向力的过载力拉动时,该收缩只能通过,这又迫使设置的内锥形套筒(11)的轴向位移 在套筒部分中,直到球径向充分移动以允许套筒(3)和主轴的较大直径的通过通过。
