Claim 1:
2. A suspension device for a turbomachine, comprising:
a clevis comprising:
a support plate configured to be attached to a casing of the turbomachine,
an annular ring portion having an aperture extending therethrough,
a peripheral frame coupling the annular ring portion to the support plate, the peripheral frame extending from opposing sides of the annular ring portion and defining an enclosed area between the annular ring portion and the support plate,
a smooth bearing formed in one piece with the clevis and attached in the aperture of the annular ring portion, said smooth bearing comprising inner and outer rings connected by a mesh structure forming a vibration filter and having a compressive and/or flexural strain capacity greater than that of the rings, the inner ring configured to receive a clevis hinge pin assembly;
a second main honeycomb-shaped mesh portion disposed within the enclosed area, independent from the smooth bearing, extending between an outer periphery of the annular ring portion and an inner periphery of the peripheral frame, the mesh structure of the smooth bearing having at least one of a compressive strain capacity and a flexural strain capacity greater than the second main honeycomb-shaped mesh portion,
wherein the support plate, the annular ring portion, the smooth bearing and the second honeycomb-shaped mesh portion of the clevis are formed in one piece from metal powder via an additive manufacturing process.
