  • the outer sleeve is pressed exactly into the inner opening of the housing.
  • a rubber stop is provided between the two elastomer bodies and has a free path with respect to the outer sleeve.
  • German utility model 296 00 679.3 describes a torque arm with a support arm which has a support surface at a first end region and a housing at a second end region.
  • An inner opening is provided in the housing, in which an inner sleeve is supported by means of at least two spaced-apart elastomer bodies. The outside of the at least two elastomer bodies lies against the inside of the housing.
  • the way of manufacturing the separate manufacture of the rubber-metal parts and the subsequent complete assembly has a number of positive properties. These positive properties are, for example, good adjustability of the rigidity of each elastomer body, usability of different mixtures for the elastomer body or good variability in the corrosion resistance.
  • a disadvantage of the method of manufacture of the supports mentioned at the outset is, however, a large number of individual parts, for the processing of which several manufacturing steps are required. This also leads to increased handling and logistics costs. Therefore, the manner of manufacturing the torque support known in the prior art is relatively cost-intensive.
  • the invention has for its object to propose a pendulum support in which the disadvantages mentioned above are avoided.
  • the pendulum support according to the invention achieves a considerable reduction in the required work steps and individual parts, as a result of which the pendulum support can be implemented at significantly lower costs.

  • the housing (s) are integrally connected to the support arm.
  • the housing can advantageously be formed in two parts. The two housing parts are positively connected to one another. This embodiment is 1*
  • the support cage is formed from two components that are as identical as possible, the manufacturing costs of the support cage elements and thus the pendulum support can be further reduced.
  • the sheet metal parts are connected in the main direction of stress by positive locking, the gaps at the joint advantageously being filled with elastomeric material.
  • the housings are integrally connected to the support arm, preferably by means of a welded connection. Due to the separate production of the housing and the support arm and the subsequent integral connection of the individual parts to a support cage, the manufacturing costs of the pendulum support according to the invention can be further reduced.
  • the support arm has two separate support arm side parts which are arranged in the pendulum support in such a way that they are spaced apart from one another in at least one partial region.
  • the support arm side parts can advantageously be pressed together in partial areas.
  • This connection is preferably made by means of a welded connection or by toxins. This can increase the rigidity and the service life of the elastomer parts.
  • At least one insert element is provided in the region of the support arm.
  • the pendulum support has at least one further area of the elastomer body, which is vulcanized directly between the support arm and the insert element and is integrally connected to the latter.
  • This Insert element has the effect that the pressure forces occurring in overrun or when reversing are transmitted to the support cage.
  • the insert element preferably consists of metal and, according to an advantageous embodiment of the invention, is cage-shaped.

  • a further housing with an inner opening can be connected to the support arm.
  • An inner sleeve is inserted into this housing before vulcanization.
  • a second area of the elastomer body is vulcanized directly into the additional housing in such a way that the outside of the elastomer body bears against the inside of the housing and is integrally connected to it.
  • the housings are advantageously integrally connected to the support arm.
  • the support arm is formed by two separate support arm side parts which are spaced apart from one another in at least one partial area.
  • an insert element can be inserted into the support arm before the vulcanization step. Simultaneously with the vulcanization of the areas of the elastomer body into the housing, a further area of the elastomer body can be vulcanized directly between the insert element and the support arm and cohesively connected to them.
  • the insertion of an insert element into the vulcanizing mold before the vulcanizing process can be dispensed with.
  • an insert element in the region of the support arm side parts can be pressed into the housing between the regions of the elastomer body.
  • an insert body that is connected to the support arm side parts of the support cage via an area of the elastomer body can be dispensed with. Nevertheless, a sufficient transfer is achieved by pressing in the insert element the pressure forces on the support cage.

  • fixation options are also conceivable.
  • the number of elements required and the number of manufacturing and assembly steps can be reduced compared to the prior art.

  • At least one insert element is inserted into the vulcanization mold in addition to the components mentioned above.
  • the insert element and the inner sleeves are connected to the support cage via a corresponding elastomer body.

  • a deliberate, defined rubber overflow significantly improves the corrosion resistance of the component and significantly reduces the tolerance requirements for sheet metal parts.
  • the pendulum support according to the invention and the method for its production can significantly reduce costs. This cost reduction results in particular from the fact that the outer sleeves of the bushing are integrated in the housing of the pendulum support, which is part of the support cage. Simple and inexpensive deep-drawn parts can also be used. Due to the permissible rubber overflow, only small tolerance requirements are required for the individual components. Finally, the number of individual parts required can be reduced by the design of the pendulum support according to the invention.
