Description

Gurnnielastic Motopiagsp

The invention relates to a rubber-elastic engine mount with hydraulic Damping, especially door liraftfahrzeugej its fluid levels, hydraulically via its throttle valve with one another connected chambers from a genius into a name, to a metallic one Abutment connected partition, each siner gunnielastic iTmfangwand and rigid by a bearing outside encompassing bracket interconnected metallic forehead viänä en exist.

In such a known cast-elastic engine mount are the load-bearing end walls for the Gununielastic Ur.fangsv; änds rigidly through an interdependence that does not grasp the position on the outside tied together. In this way iia should be opposed to a centric Connection of the end walls with each other can be achieved, that the cross section of the throttle point between the two working chambers of the engine mount does not change even with such loads changed, which do not act in the axial direction, which is the case, for example, with twisting forces or cardiac loads could. The bracket connecting the end walls is in the known one Bearing a separate part, soft with the end walls in disadvantageous v / ei se due to screw connections ssittsls screw coirsn and nuts, if necessary.

The invention is based on the object, the known bearing

The rubber-elastic partition 7 is connected via a vulcanized metallic abutment IC in the installed state on motor vehicles of the vehicle frame, whereas the connection of the engine mount 1 to the motor of the motor vehicle is made via a bolt 11 which is firmly connected to the engine-side end wall 8

st

The rubber-elastic peripheral walls 5 and β of the working chambers 3 and 4 of the engine mount 1 have a frustoconical cross-section, seen from the partition to the end walls diverging shape and are connected to sheet metal ring 12, 13, which are welded or clamped to the end walls 8, 9. The end walls 8, 9 are rigidly on the outside of the engine mount encompassing. Brackets 14 in connection with one another. The bracket 14 is shown in one piece with the end wall 9 and with his free ends 15, 16 blurred with the cover-like front wall 8 The connection can also be made by flanging, bending, folding, clamping or punching.

The actual shape of the bracket 14 as a profiled sheet metal part Figure 2 of the drawing can be seen.
