Patent ID: 7631855

Claim:
Method of using a vibration isolator having a first mounting plate and having a second mounting plate, and having at least one wire cable piece which is connected both to the first mounting plate and to the second mounting plate, the wire cable piece being connected to the two mounting plates in such a way that it extends rectilinearly between the two mounting plates and having a high rigidity in the axial direction as a result of which the resonant frequency is pushed out of the main range of frequencies generated by an engine block of a motor vehicle during operation and further having a low rigidity in the direction of a plane perpendicularly with respect to the axial direction to permit expansions in this plane, the method comprising the step of fastening the first mounting plate of the vibration isolator directly to the engine block and the second mounting plate of the vibration isolator directly to an exhaust manifold which is connected to the engine block, or fastening the first mounting plate of the vibration isolator directly to the engine block and the second mounting plate directly to an exhaust gas catalytic converter which is connected fixedly to the exhaust manifold.
