摘要:
A cone pulley pair for a cone pulley transmission comprises an input shaft which is connected rigidly to a fixed disc, a moving disc which is arranged fixedly in terms of rotation and axially displaceably on the shaft, an input component which can be driven by a drive motor, a torque sensing device having a first component which is in torque-transmitting engagement with the input component and has first shaped surfaces, and having a second component which is in torque-transmitting engagement with the moving disc and has second shaped surfaces, and rolling bodies which are arranged between the shaped surfaces, which shaped surfaces are configured in such a way that, as the torque which acts between the shaped surfaces increases, the shaped surfaces are moved away from one another counter to a force which pushes the shaped surfaces towards one another, with rolling of the rolling bodies which are arranged between them, the shaped surfaces being configured in such a way that, in the case of a low or absent force which pushes them towards one another, they are moved away from one another in such a way that the rolling bodies run over the shaped surfaces and the torque transmission between the first component and the second component is interrupted.
摘要:
A torque-limited coupling element is described, comprising an input part and an output part, each mounted rotatably about a common rotational axis, and at least one connecting means. If a predeterminable limit torque acting between the input part and output part is exceeded, the connecting means can be transferred from a first position, in which the connecting means non-rotatably connects the input part and output part to one another forming a positive engagement, into a second position, in which the input part and output part are mounted rotatably relative to one another. Furthermore, a method for torque-limited coupling and uses for such a coupling element are described. The invention is characterized in that the at least one connecting means is, in the first position, non-positively operatively connected, indirectly or directly, to a displacement body movably mounted inside a chamber filled with a magnetorheological fluid, with the position of the displacement body inside the chamber being supported by a displacement force caused by the magnetorheological fluid, a unit generating a magnetic field is provided on or in the region of the chamber and can be used to influence the displacement force of the magnetorheological fluid, and, if the limit torque is exceeded, the displacement body can be deflected inside the chamber against the displacement force caused by the magnetorheological fluid.
