A dome mount or strut mount is part of the chassis of motor vehicles . It is located above the spring on the shock absorber .
The dome mount connects the strut and the body . It enables the strut to be rotated in the strut dome as well as a slight change in the angle of the strut to the body. In addition, depending on the structure, it also has a damping function.
In modern series vehicles, the dome bearing consists of a rubber-metal element that is somewhat deformable and thus allows the angle of the strut to be changed in relation to the body. In the center of the dome bearing there is a roller bearing that guides the strut. This allows the strut to rotate relative to the body when steering. The dome bearings of the rear axle usually do not have ball bearings, as the rear suspension struts do not need to turn. This design is also known as a support bearing .
In motorsport , dome bearings made of metal are also used, in which the angle change is ensured by a ball joint . These allow a more precise steering; however, this advantage is paid for by the disadvantage of poorer vibration damping.
