Definitions

  • the invention relates to a spreading tool for expanding a clamping sleeve, which is slotted for clamping receiving a cylinder tube and in the region of its clamping slot two symmetrically to the clamping slot and parallel to a radial slot defined by the clamping slot extending clamping tongues, which extend coaxially with each other and transverse to the clamping sleeve Through holes are provided, wherein the spreading tool has a U-shaped base body with two mutually parallel U-legs, which are fixedly connected to each other via a connecting web and provided with adjustable fixing screws, which have holding pins, via which the spreading tool with the through holes of the clamping tongues can be brought into engagement and, wherein the connecting web has an adjusting screw with a rotatably mounted expanding wedge, which can be introduced by adjusting the screw between the clamping tongues and the clamping tongues apart during the adjusting movement.
  • a spreading tool of the generic type is for example from the DE 89 04 751 U1 known.
  • clamping sleeves which are tube-like and have a clamping slot.
  • Such clamping sleeves are used for example in vehicle technology in the area of the chassis and serve to hold the cylinder tube of a spring damper leg on the steering knuckle of the vehicle axle.
  • the clamping sleeve is arranged on the steering knuckle and inserted into this clamping sleeve, the cylinder tube of the spring damper leg.
  • the clamping sleeve has two clamping tongues arranged symmetrically to the clamping slot and running parallel to a radial defined by the clamping slot.
  • clamping tongues are provided with through holes extending transversely to the longitudinal center axis of the clamping sleeve through which a corresponding clamping screw can be inserted.
  • a clamping nut is placed so that the distance of the clamping tongues is reduced by tightening the clamping nut, whereby a clamping action of the clamping sleeve is reached.
  • the cylinder tube is held tightly in the clamping sleeve after tightening the clamping screw.
  • spreading tools of the generic type are used.
  • clamping connections described above between a cylinder tube and a clamping sleeve can only be seen as an example. Such clamp connections are also known in other embodiments.
  • the ball joint journal of the ball joint is received in a bearing eye of the steering knuckle, wherein the bearing eye is also provided with two clamping tongues.
  • the bearing eye forms the clamping sleeve, which also has to be widened to remove the ball and socket pivot.
  • the clamping screw is first removed from the through holes of the clamping tongues.
  • the spreading tool is designed such that it can be brought into engagement with the through bores.
  • such a spreading tool on a U-shaped base body which is provided with two mutually parallel and spaced U-legs. These U-legs are fixedly connected to each other via a connecting web.
  • Each of the U-legs is provided with a through-thread, wherein the two through threads of the U-legs are coaxial with each other.
  • Fixing screws are screwed into the passage threads from the outside, which in each case have retaining pins in their mutually facing end region, with which the fixing screws can be brought into engagement with the through bores.
  • the fixing screws are turned back, so that the two U-legs can be aligned with their through threads and thus also with the fixing screws coaxial with the through holes of the clamping tongues.
  • the holding pins of the fixing screws engage with the through holes of the clamping tongues.
  • the main body of the expansion tool is fixed to the clamping tongues of the clamping sleeve.
  • a continuous adjusting thread is provided in the region of the connecting web, which extends at right angles to the two through threads of the U-legs.
  • this adjusting thread is arranged symmetrically to the two U-legs in the connecting web.
  • an adjusting screw is screwed, in which an expanding wedge is rotatably mounted.
  • This expanding wedge extends beyond the set screw to the two clamping tongues and will pressed by adjusting the adjusting screw between the two clamping tongues. Due to the wedge shape of the expanding wedge, the clamping tongues are now pressed apart as the adjusting screw is tightened, thereby causing the clamping sleeve to widen.
  • the cylinder tube of the spring damper leg can now be removed from this clamping sleeve, so that the spring damper leg can be exchanged.
  • a tapered expanding wedge is provided which can be pressed in as far as desired between the two clamping tongues. This can, depending on the axle, lead to an inadmissible expansion of the clamping sleeve, so that the reassembly of a cylinder tube of a new spring damper leg is difficult.
  • the clamping sleeve is designed as a cast component, it may even lead to breakage of the clamping tongues or of the clamping sleeve if the clamping tongues are pressed too far apart by the expanding wedge.
  • the invention has the object to design a spreading tool of the generic type such, that on the one hand sufficient expansion of a clamping sleeve is ensured and on the other hand, the expansion is limited by pushing apart the clamping tongues.
  • the object is achieved in that the expanding wedge is formed butt-shaped and at its opposite end of the screw on the screw towards extending wedge surfaces has, which are limited in the direction of the screw by radially expanded stop shoulders.
  • a spreading tool is provided by means of which a clamping sleeve can be widened securely over their clamping tongues without an impermissible deformation of the clamping sleeve occur and no collision of the expanding wedge can be done with a protruding into the clamping slot of the clamping sleeve in rotation.
  • the expanding wedge is provided in the region of its stop shoulders with a predefined width, which is sufficiently large to effect a sufficient widening of the clamping sleeve by pushing apart the clamping tongues, without an impermissible deformation of the clamping sleeve occurring.
  • the expanding wedge has two lateral chamfers in the region of its free end. Due to the chamfers of the expanding wedge is much easier between the two clamping tongues of the clamping sleeve attachable.
  • the expanding wedge has a cylindrical portion over which the expanding wedge is rotatably and interchangeably mounted in a cylindrical recess of the adjusting screw.
  • the expanding wedge is provided with a screw which protrudes outwards through the adjusting screw, by means of which the expanding wedge can be aligned manually on the course of the clamping slot of the clamping sleeve.
  • the fixing screws have a radially enlarged screw head and that between the screw heads and the U-legs of the body a spacer sleeve is interchangeable.
  • guide sleeves are mounted interchangeably on the retaining pin whose outer diameter is smaller than the diameter of the through holes of the clamping tongues.
  • This embodiment allows an adaptation of the expansion tool according to the invention to different dimensions of clamping tongues and their through holes by the guide pins of the fixing screws in a simple manner guide sleeves with different outer diameters are placed.
  • the outer diameter of the guide sleeves is always to choose something smaller than the diameter of the through holes of the clamping tongues.
  • the guide sleeves are still safe to use in the through holes, if their inner surfaces are affected, for example, by corrosion and thus their effective inner diameter have become somewhat smaller after prolonged operation of the clamping sleeve.
  • Fig. 1 shows a sectional view of a spreading device 1 according to the invention, which is formed from a U-shaped base body 2.
