Definitions

  • the invention relates to a clamp body locking device for blocking a linear movement of a rod. Furthermore, the invention relates to the use of such a clamp body locking device.
  • Linear movements are common in many fields of technology, such as building technology in sliding doors, in mechanical engineering in machines that perform feed and feed movements, in linear positioning and handling systems, and in rail vehicles with linear motors. In such systems, it is necessary for safety reasons, for example, to decelerate or completely block the linear movement.
  • DE 1 097 217 discloses an adjustable clamping device for bars.
  • an axially displaceable clamping housing is arranged, in which rolling bodies under spring load in a conical seat of the housing pressed and releasable from its clamping seat under the action of a counter-pressure body.

  • To achieve the object of the invention specified in claim 1 clamp body locking device and in claim 10 whose use is proposed.
  • Optional advantageous embodiments of the invention arise wholly or partly from the dependent claims.
  • the inventive clamping body locking device for blocking a linear movement comprises a clamping body locking unit with two switching states, a rod and a housing.
  • the two switching states are an open and a closed or locked switching state.
  • the open switching state the rod relative to the housing is linear, that is axially displaceable to the longitudinal axis of the rod.
  • the closed switching state however, a relative linear displacement between rod and housing is locked.
  • the sprag blocking unit has two sprag cage cages arranged on the rod, which are arranged axially next to one another and guide a multiplicity of clamping bodies cooperating with ramp contours, a control fork arranged axially between the two sprag cage cages, which is movable orthogonally to the longitudinal axis of the bar, and an actuator opening the control fork.
  • the blocking effect arises by means of axial displacement of the clamping body cages each other.
  • a rafter contour is understood to mean a slope that runs obliquely to the longitudinal axis.
  • the slope of the ramp contour represents a clamping surface for the clamping body.
  • the surface of the rod represents a further clamping surface, so that in the closed switching state of the clamping body locking device, the clamping body between the rod and the ramp contour are clamped.
  • each slope of the ramp contour encloses an angle between 1 ° and 15 ° with the longitudinal axis of the rod.
  • the sprag cages are preferably designed as identical parts.
  • the two identically designed clamping body cages are arranged mirror-inverted axially next to one another, so that an axis symmetry is created between the two facing end faces.
  • the guided in the sprag cage cages are preferably designed as balls or rollers.
  • the rollers may, for example, have a cylindrical shape or a bone-like shape, that is to say a cylindrical shape with a central constriction.
  • the housing encloses the sprag cages, the control fork and the actuator.
  • the housing may be formed integrally or in several parts.
  • the actuator of the clamping body blocking device is designed as an electromechanical actuator, in particular as an electromagnet.
  • An electromechanical actuator is described for example in DE 10 201 1 077 733 A1.
  • the electromechanical actuator is designed as a linearly acting lifting magnet. That is, the solenoid allows orthogonal movement to the longitudinal axis of the rod.
  • the movement of the control fork by means of the electromagnet is also referred to as adjusting movement of the control fork.
  • the sprag cages preferably each have two control contours, which correspond to the control fork.
  • the control contours on a respective clamping body cage are arranged diametrically opposite one another. All control contours are preferably identical.
  • control contour of the clamping body cages corresponding to the control fork has a progressive curve on which the control fork is guided.
  • a progressive curve is understood to mean a control contour in which the axial displacement of the two clamping body cages is not increased linearly, but progressively. This means that at constant speed of the control fork whose movement is converted into an increasing speed in the axial direction of the clamping body cages. This in turn means that the translation changes during the course of the positioning movement.
  • the control fork and the sprag cages thus represent parts of a progressive actuating gear.
  • At least one spring bears against the end faces of the clamping body cages which are remote from one another.
  • the springs are for example as Druckfe- formed and support the release of the closed state switching by the axially opposite springs to move the sprag cages each other.

  • the additional elements are in each case arranged axially next to the clamping body cages from the front side facing away from the control fork.
  • the additional elements are pressed into the housing or glued or welded to the housing.
  • the usual in mechanical engineering positive and positive connection techniques, such as screw, are also conceivable.
  • the ramp contours are formed on the inner wall of the housing. This means that the ramp contour is integrated directly in the housing and the inner wall of the housing is shaped as a ramp contour.

  • the number of groove-shaped raceways on the rod corresponds to the number of clamp bodies arranged in a sprag cage.
  • the slopes of the ramp contours also have longitudinal grooves in which also engage the clamping body.
  • the groove-shaped raceways reduce the resulting surface pressure in the closed switching state of the clamp body locking device.
  • the rod may also have a circular cross section or a polygonal cross section, in particular hexagonal or octagonal cross section. When using a rod with a polygon cross-section cylindrical rollers are suitable as a clamping body.
  • the rod preferably protrudes on one side of the housing. This means that one end of the rod ends in the housing.
  • the clamp body locking device is used for example as a switchable motor support. This means that the clamp body locking device is used as a switchable support between the engine and the vehicle body or subframe.
  • the rod is connected to the internal combustion engine or to the vehicle body. The part not connected to the rod is connected to the housing of the clamp-locking device.
  • the open switching state of the clamp body locking device is connected.
