A spring functional component for a hydroelastic bearing (1), comprising an inner mounting connection and comprising an outer mounting connection that radially surrounds the inner mounting connection, comprising a spring body which at least partially delimits at least two working chambers (21, 23) for receiving a damping fluid and which couples the inner mounting connection and outer mounting connection to one another in order to permit a relative movement between the inner mounting connection and the outer mounting connection, and comprising a supporting frame (7) which surrounds the inner mounting connection and which is composed of a rigid material such as plastic or metal, wherein each of the at least two working chambers (21, 23) issues into at least one radial opening which is open to the radially outer side of the spring functional component and which can be closed off by a connection part for coupling to the outer mounting connection, wherein at least one radially inwardly extending radial stop is fastened to a radial inner side (13) of the supporting frame (7) in order to limit the relative mobility of the mounting connections at least in a radial direction.

A vibration damping device (10) comprises a tubular outer attachment member (11) and an inner attachment member (12); a pair of main rubber portions (13) that couple the outer attachment member (11) to the inner attachment member (12), and that are arranged so as to be spaced in an axial direction along a central axis (O) of the outer attachment member (11); and a partition portion (15) that couples the outer attachment member (11) to the inner attachment member (12), and that partitions a liquid chamber (25) between the pair of main rubber portions (13), in the axial direction, into a first liquid chamber (26) and a second liquid chamber (27). The partition portion (15) comprises an annular rigid portion (30) in which a restricted passage (33) that connects the first liquid chamber (26) to the second liquid chamber (27) is formed, and an annular elastic portion (29) that is adjacent to the rigid portion (31) in the radial direction. The elastic portion (29) is compressed and deformed in the radial direction and makes contact with the rigid portion (30) in an unbonded state.

A hydraulic body mount with a combined rubber cushion and a hydraulic module may include an inner shaft, a mounting plate, a mounting bracket, a main rubber element, an inner ring, a fluid track, an upper bellows, a washer, a lower bellows, an outer can, a rate plate, a lower bushing, a crash washer, a doubler plate, and a retainer bracket. The fluid track may be configured to receive a fluid via a fluid port. The upper and/or lower bellows may be configured to interact with the fluid. The rate plate may be configured to engage the lower bushing and may be deformed when receiving the at least a portion of the inner shaft.

A method for producing a bearing, in particular a hydraulic axle support bearing, which comprises the following steps: preassembling an inner part in an outer part with an elastomer body which is arranged in between and is reinforced by a plastic cage which at least partially bears against an inner wall of the outer part. The plastic cage is configured to radially protrude over an upper edge and a lower edge of the out part and, at the lower edge of the outer part, to project over the latter. Simultaneously calibrating the outer part and the plastic cage by constricting the outer part and the plastic cage from a respective first diameter to a respective second diameter which is smaller than the respective first diameter. After the constriction, the plastic cage projects over the upper edge of the outer part for the form-fitting axial securing of the outer part.

An elastic joint, in particular for a wheel suspension of a motor vehicle. The joint includes an inner armature, an outer armature surrounding the inner armature, wherein the armatures define an axial direction and two radial directions perpendicular to the axial direction as well as perpendicular to each other and disposed in a circumferential plane, and an elastomeric body for the mutual elastic retention of the armatures, wherein the elastomeric body consists of at least four connecting columns respectively extending from the inner armature to the outer armature.

A hydraulic bearing is provided and including: an inner core, a cage surrounding the inner core, an elastomer body extending between the inner core and the cage and elastically connecting them to each other, and an outer sleeve enclosing the cage. The elastomer body has a support spring, first and second radial fluid chamber recesses, and first and second axial fluid chamber recesses. The first and second radial fluid chamber recesses and the first and second axial fluid chamber recesses are each filled with a working fluid and limited radially outwardly by the outer sleeve to form first and second radial fluid chambers, and first and second axial fluid chambers, respectively. The first and second radial fluid chambers are fluidically connected to each other via a radial fluid channel. The first and second axial fluid chambers are fluidically connected to each other via an axial fluid channel.

A hydraulic composite bushing includes: a core shaft, with a continuously spiral fluid channel groove; a rubber member, arranged around the core shaft, and having two recesses formed radially outside of the fluid channel groove and radially opposite to each other; a support ring arranged around the rubber member; an outer cover pressing on the support ring from a radially outer side thereof; and a sealing device provided at each end of a fluid channel tube arranged within the fluid channel groove. Two ends of the fluid channel tube pass through the rubber member radially to extend into two hydraulic chambers respectively, with the hydraulic chambers in communication with each other through the fluid channel tube. One end of the sealing device is arranged inside the flow channel groove and the other end thereof passes through the rubber member to extend into the hydraulic chambers.
