Definitions
- the inventions relate to the manufacture of a clutch according to the preambles of claims 1, 5 and 7.
- Such clutches are used together with two-part stabilizers in automotive engineering.
- each axle of a motor vehicle is equipped with a stabilizer.
- This stabilizer works on the principle of a torsion bar and is arranged parallel to the vehicle axle, with both ends each being attached to a wheel suspension.
- This stabilizer significantly prevents or weakens the transmission of the roll movements caused by the road conditions and originating from the wheels to the vehicle. This makes driving behavior more stable and therefore safer on uneven roads and in curves.
- One-piece stabilizers are tailored to certain Farirbahn conditions and can therefore only be used to a limited extent.
- Split stabilizers are used whenever vehicles are designed for both the road and the terrain. Such a stabilizer is described for example in DE 100 12 915 AI.
- This stabilizer consists of a first stabilizer part and a second stabilizer part, both of which are connected to one another via a clutch.
- the clutch consists of a tubular outer rotating part which is non-rotatably connected to one stabilizer part and an inner rotating part which is integrally connected to the other stabilizer part. Both the outer rotating part and the inner rotating part each have a claw, which lie on a radial plane. Two claws of an axially displaceable claw sleeve engage between these two claws and form a positive connection. Both the claws of the turned parts and the two claws of the coupling sleeve each have complicated and coordinated radial cone surfaces.
- the tubular outer rotating part and its inwardly directed cam are designed as individual parts and welded together.
- the tubular rotating part has a radial through opening in the form of an ellipse and the cams have a matching elliptical pin.
- the cam is pushed with its pin from the tube interior through the radial through opening of the outer rotating part and then welded flush from the outside.
- the cam is manufactured as a single part by machining.
- a sleeve-like turned part is manufactured that consists of a clamping shaft and a cam part.
- the cam part has a diameter that corresponds to the outer diameter of the outer rotating part of the clutch.
- This cam part is then machined to an outer diameter in the copy milling process, which corresponds to the inner diameter of the outer rotating part of the clutch, with two opposite and elliptical pins remaining.
- the cam part is then milled out in a special way in the area between the two pins so that two opposing cams, each with one pin, remain.
- the two cams are separated from the clamping shaft on a dreli machine. The team is rejected.
- the invention is therefore based on the object of simplifying the manufacture of the cam and thereby improving the quality of the outer surface of the cam. Another task is to develop a milling and a turning device for multiple machining of a cam.
- the inventions overcome the mentioned disadvantages of the prior art. With the new ner driving and the two new north directions, the costs for producing a cam are significantly reduced. This refers to the manufacturing time but also to the material requirements. This saves a considerable amount of material by shaping the cam to a large extent and cutting it only to a small extent. In addition, for milling the cam, only the relatively small cam spigot must be extended and therefore only a relatively small clamping part has to be discarded later.
- cam is formed using the cold process, because this improves the dimensional accuracy and facilitates subsequent processing.
- a particularly high quality of the cylindrical outer surface of the cam is obtained if the cam is soft-annealed after shaping, because this removes stresses, and if the cylindrical outer surface is phosphated and calibrated because better accuracy is achieved. It is also advantageous if the milling and shortening devices are designed as multiple clamping devices. This increases the effectiveness of the production.

- Fig. 18 Device for shortening in a different view.
- the outer rotating part 1 consists of an outer rotating part 1 in the form of a tube which is connected in a rotationally fixed manner to a first stabilizer part 3 via a flange 2 and from an inner rotating part 4 which is formed in one piece with a second stabilizer part 5.
- the outer rotating part 1 is equipped with a non-rotatable and inwardly directed cam 6.
- the inner rotating part 4 is connected via a toothing 7 to a cam sleeve 8 which has a cam 9 directed outwards from the rotating part 5.
- the inward cam 6 of the outer rotating part 1 and the outward cam 9 of the inner rotating part 4 lie on a common radial plane and form two opposite coupling spaces between them.
- the coupling sleeve 11 moves a certain distance and the two cams 6 and 9 and the claws 10 of the coupling sleeve 11 come out of contact but not out of engagement.
- the cams 6, 9 and the claws 10 are freely rotatable relative to one another at a limited angle and only then come back to a common stop.
- the outer rotating part 1 and the cam 6 are both designed as individual parts and welded together.
- the outer rotating part 1 has an elliptical opening extending in the axial direction, through which a correspondingly shaped cam 6 is inserted from the inside and welded to the outer rotating part 1 from the outside.
- 3 to 8 has a segment-like shape with a cylindrical outer surface 13 which is matched to the inner diameter of the outer rotating part 1 and a cylindrical inner surface 14 which corresponds to the surface of the inner rotating part 4.
- the cam 6 has two lateral conical surfaces 15, which in turn correspond to the conical surfaces of the claws 10 of the coupling sleeve 11.
- the length of the outer surface 13, the inner surface 14 and the two conical surfaces 15 are limited by a smaller end surface 16, which is directed towards the coupling sleeve 11, and by a larger end surface 17, which lies against the cam sleeve 8.
- cam pin 18 On the outer surface 13 of the cam 6 there is a cam pin 18 which has the shape of an ellipse and whose dimensions are matched to the ehpsen-shaped opening in the outer rotating part 1.
- the height of the cam pin 18 corresponds to the wall thickness of the tubular outer rotating part 1.
- Both the cam pin 18 and the opening in the tubular outer rotating part 1 are conical, so that a V-shaped weld seam results.
- This cam 6 is produced in two process stages.
- a cam 6 ' as shown in FIGS. 9 to 11, is first cold or hot formed or deformed.
- the cam 6 ' is designed with an extended cam pin 18'. This extension of the cam pin 18 'serves as a clamping pin for later processing.
- the later cylindrical inner surface 14 ' is flat or already preformed and provided with a machining edge 19.
- this cam 6 ' is soft-annealed for structural homogenization and phosphated to improve the sliding properties of the surfaces.
- the cylindrical outer surface 13 of the cam 6 ' is calibrated using a wobble press in such a way that the surface is finished and has the quality of a reference surface for further mechanical processing.
- a radial threaded bore 20 is made in the elongated pin 18 ′′ of the cam 6 ′, which is required as a saving aid for further processing.
- This device consists of a conventional vise 21, which inhibits a cam clamping bar 22.
- This cam clamping bar 22 has a width which is narrower than the later length spacing of the two end faces 16, 17 of the cam 6 'and a length such as is required to accommodate several cams 6'.
- the cam clamping bar 22 is equipped with a plurality of receiving prisms 23 aligned in a row, each of which is provided with a through bore 24.
- a clamping screw 25 is inserted from the underside of the cam clamping bar 22 into the through bore of the cam clamping bar 22 and screwed to the cam pin 18 'until tension. All exposed outer areas of the cam 6 'are thus exposed.
- the device for milling the contour surfaces of the cam 6 ' is rotated by 90 ° and the cylindrical inner surface 14 is also milled to the finished size
- FIGS. 16 to 18 a device for shortening the cam pin 18 ' is used, as shown in FIGS. 16 to 18.
- This device consists of a sleeve-like clamping body 26.
- This clamping body 26 has an outer diameter which corresponds to the outer diameter of the outer rotating part 1 of the clutch, and an axial through-hole 27 graduated in diameter.
- the larger diameter of the through-hole 27 corresponds to the inner diameter of the outer rotating part 1.
- the clamping body 26 has three openings 28 which are evenly distributed around the circumference and which are matched in shape and size to the elliptical cams 6 '.
- the device also includes a clamping sleeve 29, which is matched to the outer diameter of the inner rotating part, and a mandrel 30.
