Abstract
A flexible bearing for supporting a body, in particular, for supporting an internal-combustion engine, includes a journal bearing that may be attached to a supporting foundation and a support that may be attached to the engine. An elastic spring is connected between the journal bearing and the support while a bearing spring made of a non-creeping material is connected between the journal bearing and the support in parallel with the elastic spring. The bearing spring comprises at least one disk spring having an S-shaped spring constant curve. The disk spring and the elastic spring have load carrying capacities such that, after the weight of the body to be supported is applied to the flexible bearing, the spring rate of the disk spring is essentially zero and the rubber spring is essentially free of elastic tensions.
