Definitions
- the invention relates to a structural unit according to the preamble of claim 1.
- a structural unit with a tube provided at least on one side with a common internal thread in a first direction of rotation is described using the example of a tie rod for a motor vehicle, in which end an adjustment sleeve having a corresponding external thread is screwed into the tube.
- a shaft of a ball joint is screwed.
- the shaft has an external thread which runs counter to the first direction of rotation and which corresponds to the internal thread of the adjusting sleeve.
- the smaller diameter thread is a weak point that could lead to failure in such a tie rod.
- another disadvantage has been found in such solutions, which consists in that the shaft is inadvertently unscrewed so far from this receiving adjusting sleeve, that only a small threaded portion for transmitting power is available or the shaft even completely from the Justierhülse solves. This risk is further aggravated by damage to the threads.
- the DE 77 32 250 Ul is a solution that limits the axial displacement of the tube relative to the shaft.
- the presented in this document and compared with the previously described track rod similarly constructed unit also allows the adjustment of the adjusting sleeve over a key area existing for this purpose, so that the shaft and the tube can move relative to each other in the axial direction.
- a special feature of this design is to be considered that here is usually used on tie rods bolting used to fix the assembly to attach a locking member to the tie rod.
- the locking member consists in the present example of a metal strip having an angled end portion. This angled end portion rests on a plane surface formed on the shaft for this purpose. Viewed in the extension direction of the shaft, this further has a groove in which the bent end portion of the sheet engages when the shaft is released beyond a permissible axial displacement out of the screw.
- the production engineering effort to produce the flat surface on the shaft is disadvantageous.
- this embodiment has a considerable installation effort.
- Another disadvantage is further that the sheet metal strip is located outside of the tie rod and thus damage or deformation of the metal strip can not be excluded during normal use of the tie rod in motor vehicles, so that its function might be disabled.
- this sheet metal section is exposed to increased environmental influences and there is consequently the risk that it prematurely corrodes or wears.
- a structural unit is provided with a tube provided in a first direction of rotation common thread, in which end an adjustment sleeve is screwed.
- the adjusting sleeve in this case has an opposite to the first direction of rotation internal thread with a shaft screwed therein, the adjustment is limited by a penetrated by the shaft, the adjusting sleeve associated locking member.
- the invention is based on the technical object of providing a structural unit with two components which can be adjusted relative to one another, which allows a simple and reliable limitation of the axial adjustment path.
- a first and particularly simple embodiment of the invention provides that the groove along the outer circumferential surface of the shaft is designed to run circumferentially.
- This variant represents a particularly simple manufacturing possibility.
- the groove only on a part of the circumference of the outer circumferential surface of the shaft is introduced.
- the locking member should preferably be inserted into an inserted into the inner circumferential surface of the adjusting sleeve groove.
- the adjustment sleeve can be produced together with the locking member as a prefabricated unit before the final assembly of the assembly according to the invention takes place.
- the assembly has been simplified as a whole.
- the locking member has a passage opening whose clearance corresponds to the outer dimensions of the groove of the shaft. This has the consequence that in the assembled unit, the locking member rests with the surface of the passage opening on the surface of the groove of the shank. Thus, an axial mobility is given within the groove in order to define the adjustment of the assembly. During the adjustment movement, the locking member thus slides with its passage opening along the groove of the shaft.
- the shaft has a mushroom cap-shaped end piece and the outer dimensions of this end piece are larger than the inside diameter of the passage opening of the locking member.
- the locking member should have inherent elasticity.
- the shaft is introduced with its mushroom-shaped end piece in the passage opening of the locking member, which consequently widens due to its inherent elasticity within the groove of the adjusting sleeve in the radial direction and can be performed on the mushroom cap-shaped end of the shaft.
- the locking member contracts due to its inherent elasticity, so that it has approximately a passage opening corresponding to the circumference of the outer circumferential surface of the groove within the shaft.
- the locking member is now in the groove of the shaft directly to the surface of the groove.
- the groove of the shaft has two lateral abutment flanges, which limit the axial displacement of the assembly.
- the abutment flanges serve as a stop for the locking member.
- the mushroom cap-shaped embodiment of the end piece of the shank can be such that the end piece of the shank has a spherical, conical or conical contour. It is only important here that the outer dimensions of the shank expand from its end towards the groove, so that the locking member guided over the end piece experiences, due to its inherent elasticity, an enlargement of its passage opening when the assembly is mounted. Behind the mushroom cap-shaped end piece is the groove of the shaft, in which then engages the locking member.
- the adjusting sleeve can also have on its outer, free, protruding from the tube side a key surface for applying a tool.
- This key surface thus serves to adjust the assembly by a rotary motion is transmitted to the Justierhülse, which causes due to the counter-rotating thread on a-zu-move away or a moving away of the tube relative to the shaft.
- a structural unit according to the invention is that the assembly is part of a tie rod for motor vehicles and the shaft therefore the end of a
- Ball joint housing shaft of this tie rod is.
- the above-mentioned advantage will be apparent, after which the solution according to the invention can be taken directly into current series products without significant additional expenses.
- tie rods which are already in use and as they have been explained in connection with the documents to the prior art, the components tube, Justierhülse and shaft are already present. It is only necessary to provide a groove on the shank and form the mushroom cap-shaped end piece and to introduce a groove in the inner sleeve of the assembly, in which then the locking member according to the invention can be used. With these few changes can be the inventive unit directly for numerous applications use.
- FIG. 1 The enlarged representation of the structural unit according to the invention shown in detail in FIG. 1 represents a component of a tie rod for a motor vehicle.
- FIG. 1 corresponds to the detail I in FIG. 2.
- the assembly shown has a tube 2 with an internal thread 1.
- an adjusting sleeve 3 is screwed with an existing on the adjusting sleeve 3 corresponding to the internal thread 1 of the tube 2 external thread 17.
- the inner sleeve 3 has on its inner circumferential surface 8 via an internal thread 4, which serves to screw a shaft 5 in the adjusting sleeve 3.
- the shaft 5 has on its outer circumferential surface for this purpose an external thread 18.
- the internal thread 1 of the tube 2 and the internal thread 4 of the adjusting sleeve 3 are mutually oppositely executed thread.
- the internal thread 1 of the tube 2 is a right-hand thread
- the internal thread 4 of the adjusting sleeve 3 is designed as a left-hand thread. This has the consequence that during a rotational movement of the adjusting sleeve 3 about the common longitudinal center axis of the components tube 2, not shown Adjusting sleeve 3 and shaft 5 of the shaft 5 can be moved relative to the tube 2.
- the adjusting sleeve 3 also has a groove 9 into which a limited elastic locking member 6 is inserted. The locking member 6 can escape within the groove 9 in the radial direction. An axial mobility of the locking member 6 within the groove 9 is not provided.
- the locking member 6 is located with its two side surfaces on the corresponding boundary surfaces of the groove 9.
- a groove 7 is further introduced, which is located in the region of the end portion of the shaft 5.
- This groove 7 is bounded on both sides by a respective abutment flange 19 and 20 respectively.
- the area between the abutment flanges 19 and 20 represents the maximum possible displacement of the structural unit according to the invention.
- the locking member 6 also has a passage opening 10, the inner surface of which rests directly against the outer surface of the groove 7 of the shaft 5. A sliding movement in the axial direction within the groove 7 is ensured in the present case.
- the end piece 11 of the shaft 5 is designed mushroom cap-shaped.
- the mushroom-shaped contour of the end piece 11 of the shaft 5 is achieved by a plurality of merging into each other geometries.
- two cone-shaped geometries with different gradients alternate with the longitudinal center axis.
- this has a circular-cylindrical cross section, which merges into the stop flange 20 on the groove side.
- the assembly of the assembly takes place as follows:
- the locking member 6 is inserted into the groove 9 provided for this purpose in the adjusting sleeve 3.
- the locking member 6 has an intrinsic elasticity, which makes it possible, when screwing the shaft 5 into the adjusting sleeve 3, first to guide the mushroom-cap-shaped end piece 11 of the shaft 5 through the through-opening 10 of the locking member 6. Due to the said inherent elasticity, the locking member 6 expands within the groove 9 in the radial direction. It slides with its access opening 10 on the conically shaped geometries of the end piece 11 along.
- the locking member 6 engages in the groove 7 of the shaft 5 and retracts due to its inherent elasticity, so that it rests on the surface of the groove 7. Now, the thus created part assembly can be screwed over the external thread 17 of the adjusting sleeve 3 in the internal thread 1 of the tube 2.
- FIG. 2 shows a structural unit based on the example of a tie rod 13 for a motor vehicle for a better understanding of the solution according to the invention.
- the tie rod 13 of which only one end piece is shown here, has a tube 2 into which the adjusting sleeve 3 is screwed.
- a key surface 12 is present on its outer circumferential surface.
- a ball joint 14 is connected to the adjusting sleeve 3.
- a clamp 15 is tightened by a screw 16 and thus braces the assembly as a whole. This makes it impossible to realize an adjusting movement after tightening the clamp.
- the structural unit according to the invention is located inside the tube 2 of the illustrated tie rod 13, thus protecting it against contamination and mechanical damage.
