Abstract: A hydro engine mount for a vehicle may include a locking body including a plurality of locking portions; a body plate including a plurality of fastening grooves configured to be fastened to the plurality of locking portions, wherein a main rubber is mounted in the body plate; and a diaphragm stacked between the main rubber and the locking body.

Abstract: The present disclosure relates to a hydraulic mount having a unidirectional damping membrane. A hole is formed in a membrane and a one-way closure having upper and lower portions, which are different from each other, is inserted into the hole to control a flow of a fluid. The one-way closure means includes: a body which intermittently closes a lower side of the hole formed at a center of the membrane; a column portion which is vertically formed at a center of the body; and a moving closure which is formed at an upper portion of the column portion and closes an upper side of the hole.

Abstract: An impact energy absorbing propeller shaft may include a collet integrally and rotatably inserted between a spline portion formed on an outer circumferential surface of a front shaft and a spline portion formed on an inner circumferential surface of a rear shaft, and an O-ring fitted with an outer circumferential surface of a rear end portion of the collet, fixedly holding a rear end portion of the front shaft, and fixedly supporting the collet inside the rear shaft.

Abstract: A roll mount is provided and includes a rubber coupled to a core mounted in an exterior pipe coupled to an end of a main body, slits that are formed in the rubber at the periphery of the core, and a pocket that is disposed within the slits. The pocket includes a first pocket portion having a first and second chamber formed therein and connecting portions having flow paths that connect the first and second pocket portion and place the first and second chamber in fluid communication. A magnetorheological fluid is encapsulated in the first and second chamber, and flows therethrough, via the flow paths based on elastic deformation of the first and second pocket portion. The wound coils are disposed at exterior sides of the first and second pocket portions, and fluidity of the magnetorheological fluid is adjusted based on the electric current applied to the coil.

Abstract: An engine mount includes a nozzle plate mounted between an insulator and a diaphragm so as to divide an interior into an upper liquid chamber and a lower liquid chamber, and an annular flow path formed in the nozzle plate so that an encapsulated hydraulic liquid flows between the upper liquid chamber and the lower liquid chamber, the nozzle plate being opened at an upper side of the flow path; a shielding member which has two or more shielding plates arranged to cover the upper side of the flow path; an adjusting bolt which is rotatably mounted in a core coupled to the insulator; and a connector, in which the shielding plates are folded or unfolded in accordance with a rotation of the adjusting bolt, and a size of an upper flow path hole is determined depending on a state in which the shielding plates are folded or unfolded.
