Definitions

  • the present invention relates to a clutch link for a driving clutch and a method for producing a sintered component having connection apparatus, in particular a clutch link for a driving clutch.
  • Clutch links of this type for a driving clutch which is also referred to as a claw clutch
  • a driving clutch which is also referred to as a claw clutch
  • the receptacle chamber comprising a contact surface and a counter surface, which points toward the contact surface.
  • the connection to the particular other clutch link is produced in that the other clutch link is entirely or partially placed in the receptacle chamber, for example, using a projection.
  • the manufacturing tolerances of the other clutch link and/or projection and the receptacle chamber are selected as needed so they match with the particular desired type of fitting, i.e., play fitting, transition fitting, or excess fitting. Small tolerances may typically be achieved by machining reworking, which is connected with significant additional effort above all in the event of hard and/or brittle materials, such as ceramics, glasses, sintered metals, etc.
  • the invention provides a clutch link for a driving clutch, which has a receptacle chamber for receiving another clutch link of the driving clutch.
  • the receptacle chamber comprises a contact surface and a counter surface, which points toward the contact surface.
  • a hole is implemented behind the counter surface and is connected via a gap to the receptacle chamber. The hole extends parallel to the longitudinal axis of the driving clutch.
  • a spring element is situated in the hole and has a contact area for contact on the other clutch link, which protrudes through the gap into the receptacle chamber.
  • the receptacle chamber of the proposed clutch link which is also referred to as a first clutch link here, receives the other clutch link, which is to be connected to the first clutch link and is also referred to as a second clutch link here, this being understood to mean that the second clutch link is at least partially located, for example, using a projection, in the receptacle chamber.
  • the invention additionally provides a clutch link for a driving clutch, which has a projection for insertion into a receptacle chamber of another clutch link of the driving clutch.
  • the projection comprises a contact surface and a counter surface, which points away from the contact surface.
  • a hole is implemented behind the counter surface and is connected via a gap to the external chamber located in front of the counter surface, i.e., to the receptacle chamber, if the projection is inserted into the receptacle chamber.
  • the hole extends parallel to the longitudinal axis of the driving clutch.
  • a spring element is situated in the hole and has a contact area for contact on the other clutch link, which protrudes through the gap into the external chamber located in front of the counter surface, i.e., the receptacle chamber, if the projection is inserted into the receptacle chamber.
  • the receptacle chamber of the other clutch link which is also referred to as a second clutch link here, receives the proposed clutch link, which is to be connected to the second clutch length and is also referred to as a first clutch link here, this being understood to mean that the first clutch link is at least partially located, for example, using the projection, in the receptacle chamber.
  • the spring element has its contact area protruding far enough into the receptacle chamber so that it presses against the second clutch link with bias tension and presses it against the contact surface.
  • the second clutch link is thus, at least in the context of the spring force of the spring element, connected to the first clutch link without play. Even greater tolerances of the first and second clutch links may be compensated for and nonetheless play-free fitting may be achieved.
  • the production of clutch links having greater tolerances is simpler and more cost-effective, even if one considers the additional outlay for holes and spring elements, which are provided in the proposed first clutch link. This is because the holes may be generated very cost-effectively and precisely positioned, for example, by casting, compression, etc.
  • the spring elements may also be produced very cost-effectively and inserted into the holes, for example, automatically.
  • the proposed clutch links are particularly suitable for dynamically loaded systems.
  • dynamic forces in particular in the event of oscillating or swelling forces, high tension peaks occur in the connected clutch links, which may result in fracture, in particular, at notch-sensitive points.
  • These dynamic forces become more and more critical the greater the play there is in the connected clutch links. Therefore, clutch links having low ultimate elongation and/or greater brittleness, such as clutch links made of sintered hard metal, ceramic, glass, and the like, are particularly endangered.
  • the spring force can be selected via the spring elements so that no play occurs even at maximum load. In this way, the safety factor against fracture is increased and/or material thickness is saved and/or materials which are more cost-effective because they are more brittle can be used.
  • a further advantage is in the frequent cases in which the dynamic forces cannot be ascertained beforehand, in that in these cases the geometry of the clutch links does not have to be altered. Rather, the diameter and position of the holes may be maintained and various spring elements, which have different spring constants with equal external dimensions, may simply be tested out, because they may be replaced easily.
  • each of the proposed clutch links comprises a sintering material. Because finished sintered clutch links are typically very hard, and may therefore only be reworked by machining with great effort and tool wear, it can be viewed as a further advantage in each of the proposed clutch links that because of the possible greater tolerances, machining reworking of this type is only required to a greatly reduced extent, or even not at all.
  • the form of the clutch link in particular the depressions such as the receptacle chamber and the holes, can be designed without undercuts, so that the original shaping, for example, by casting, compression, etc., can be performed using little effort and simple molds, which is advantageous in particular with sintered components.
  • Each of the proposed clutch links can be provided, as needed, with at least one further hole and at least one further spring element in each further hole, each of the further holes being connected via a gap to the receptacle chamber, and each of the further spring elements having a contact area for contact on the other clutch link, which protrudes through the particular gap into the receptacle chamber.
  • a further hole can be implemented behind the counter surface. The two holes are thus adjacent to one another on the same side of the receptacle chamber. The other clutch link is pressed against the contact surface by the spring elements seated in the two holes at two adjacent areas.
  • a further hole can be implemented behind the contact surface.
  • the two holes are thus directly opposite to one another or are offset to one another on the two sides of the receptacle chamber pointing toward one another.
  • the other clutch link is pressed by the spring elements, which are seated in the hole behind the counter surface and are also referred to as first spring elements here, against the further spring elements, which are seated in the further hole behind the contact surface and are also referred to as second spring elements here, and/or clamped between the first and second spring elements, if the two holes and thus the first and second spring elements are directly opposite to one another, or in the other case, in which the two holes and thus the first and second spring elements are offset to one another, it is pressed by the first spring elements against the contact surface and by the second spring elements against the counter surface.
  • the first and second alternatives may also be combined, however, so that three holes and corresponding first, second, and third connection elements are provided, of which two holes lie behind the counter surface and one lies behind the contact surface, or vice versa.
  • a fourth hole and at least one further fourth spring element in this fourth hole may also be provided.

  • the spring element can preferably comprise a hollow cylinder, which has a slot running between the two front faces.
  • the slot preferably runs parallel to the longitudinal axis of the hollow cylinder, but can also run diagonally.
  • the hollow cylinder is preferably produced from strip material made of spring steel, but can also comprise any other material suitable for the particular application, such as plastic.
  • the spring element can also be shaped differently as needed, however, and comprise a ring which has a slot, for example.
  • the ring is preferably produced from wire material made of spring steel, but can also comprise any other material suitable for the particular application, such as plastic.
  • a protrusion can project from the peripheral surface of the hole and lie in the slot of the hollow-cylindrical or annular spring element.
  • the protrusion is preferably a rib running parallel to the longitudinal axis of the hole, because it can be demolded more easily from a casting or compression mold. The protrusion prevents twisting of the spring element in the hole.
  • the spring element can be implemented as solid, for example, in the form of a pin or bolt, and can comprise an elastic material such as plastic or rubber.
  • the shape of the spring element can be selected arbitrarily as needed. Thus, for example, it can have a peripheral surface having an oval, preferably elliptical, preferably circular cross-section.
  • the shape of the hole can also be selected arbitrarily as needed and preferably corresponds to the shape of the spring element. Thus, for example, the hole can have an oval, preferably elliptical, preferably circular cross-section.
  • the spring element can press against the other clutch link using an arbitrary part as needed, however, a part of the external peripheral surface of the spring element is preferred as the contact area.
  • At least one further spring element can be situated in each hole as needed.
  • the hole can have at least one opening, whose edge protrudes at least partially radially inward. This edge is used to secure the spring element against slipping out of its hole. It is preferably implemented as a flanged edge.
  • the spring element can be fastened to the clutch link, preferably by spot welding, on at least one point, preferably in the area of the hole. This ensures the spring element is permanently secured on the clutch link and/or in the hole.
