  • recesses which are through the second support body and extend at least part of the elastic body.
  • This has the advantage that the rigidity of the elastic body can be adjusted to the Transmission of engine block vibrations to the oil pan reduce.
  • a vibration decoupling in the desired Frequency range can be reached.
  • Another advantage of the recesses is that the weight of the device according to the invention is reduced.
  • a further improvement is achieved in that the recesses are designed such that a tool through the recesses is insertable to support the first support body. This is particularly so advantageous during assembly because when connecting the first support body with the oil pan (first component) avoided bending of the first support body can be. This applies in particular to the design according to the invention, in which the first support body has tabs, which for connecting Oil pan and first support body are bent.
  • a particularly good support of the first support body during assembly can be achieved in that at least some of the recesses are arranged adjacent to the first connecting means.
  • the second support body Has connection openings through which the connecting means for Can be connected to the first component.
  • Second Connection means can be provided in particular screws, which are screwed into the engine block.
  • the present invention also relates to a pre-assembled Oil pan unit, which has an oil pan with a device connected in the manner previously described.
  • a pre-assembled Oil pan unit simplifies assembly and shortens the Assembly time at the completion of the automobile.
  • the first support body is a connecting flange of the oil pan.
  • the device 1 has a first support body 2 and a second support body 3 on.
  • the first support body 2 can be via the first described in more detail below Lanyards are set on the first component.
  • the second Support body 3 can on the not shown second connecting means second component.
  • the device according to the invention also has an elastic body 4 on, which connects the first and second support body 2, 3 liquid-tight and the first support body 2 is elastically movable on the second support body 3 sets.
  • the first support body 2 and the second support body 3 are as rigid bodies trained and made of metal, preferably steel.
  • the first and second support body formed as a circumferential body along an in closed line train.
  • the elastic made of elastomer Body 4 is, as can be seen in particular from FIGS. 3 to 7, firmly with first and second support body 2, 3 connected. Only in the 2 are first support body 2, elastic body 4 and second support body 3 shown separately from each other to the structure to better represent the device according to the invention.
  • the firm Connection of the elastic body 4 with the first support body 2 and the second support body 3 is achieved in that the elastic body 4 by Vulcanization with the first support body 2 and the second support body 3 is permanently connected. In this way, first support bodies form in the finished product 2, second support body 3 and elastic body 4 a unit.
  • the first support body can also be used as a Connection flange of the oil pan be formed. This can in particular be generated by a bent edge of the oil pan.
