  • Patent number: 8690132
    Abstract: A hydraulically damping axial mount includes a housing with an elastomeric support spring with an insertion part, a mount core part extending in axial direction (a) in the housing and supported by a support spring, and two chambers arranged underneath one another in axial direction (a) for fluidic damping. A working chamber and an equalization chamber are spatially separated by a channel unit and are hydraulically coupled with one another by a channel. One or several insertion parts which are partially covered by the elastomer of the support spring and reinforce the support spring are inserted in the elastomeric support spring. The support spring is secured in the housing by a thread pitch, formed on the outside contour of the elastomeric support spring in the circumferential direction (u) of the elastomeric support spring and brought into engagement with a corresponding inside contour of the housing during installation of the mount.
