HYDRAULIC MOUNT
A hydraulic mount includes: an outer pipe having a diaphragm defined thereon by vulcanization; a main rubber member disposed in the outer pipe by press-fitting; a core disposed inside the main rubber member; a ring stopper interposed between the diaphragm and the main rubber member; a first fluid chamber and a second fluid chamber configured by depressing both sides of an outer circumference of the main rubber member towards the core, each of the first and second fluid chambers configured to accommodate a fluid; a third fluid chamber configured to communicate with the first fluid chamber and the second fluid chamber, disposed in a part of the main rubber member under the core, and accommodating the fluid; and a fourth fluid chamber configured to communicate with the third fluid chamber and disposed between the ring stopper and the outer pipe to accommodate the fluid.
Bush-type hydraulic mount
A bush-type hydraulic mount used for mounting a motor module in an electric vehicle is provided. The bush-type hydraulic mount includes an inner pipe, a middle pipe disposed coaxially with the inner pipe, and a main rubber that is vulcanized between the inner pipe and the middle pipe. An outer pipe surrounds the middle pipe. The main rubber includes a front fluid chamber that is recessed from a surface of the main rubber, a rear fluid chamber adjacent to the front fluid chamber and recessed from the surface of the main rubber, and a bridge that separates the front fluid chamber and the rear fluid chamber to allow fluid to flow between the front fluid chamber and the rear fluid chamber and being deformable by external force.
HYDRAULIC BEARING BUSH
A hydraulic bearing bushing (1) having:—an annular rubber body (3) that comprises an inner bushing (2) for receiving a bearing journal (12),—an outer annular housing (6) against the inner circumference of which the annular rubber body is supported, —at least two chambers (7, 8) that are formed between the annular rubber body and the annular housing or within the rubber body, are able to be filled with a hydraulic fluid and are connected together via at least one equalizing and throttle channel (9) such that, when the inner bushing is loaded by bearing forces, hydraulic fluid is exchangeable between the chambers. Reinforcing members (13, 14) having a greater modulus of elasticity in relation to the rubber material are arranged in or on the annular rubber body such that, when there is a pressure increase in one of the chambers, an expansion of the rubber body corresponding to an inflation or a change in shape is able to be reduced at least in one direction.
Hydraulic mount and method of producing a hydraulic mount
A hydraulic mount is provided and includes: an inner core, a cage that surrounds the inner core, an elastomer body that extends between the inner core and the cage and elastically connects them to each other, and an outer sleeve that encloses the cage. The elastomer body has a first circumferential fluid chamber recess and a second circumferential fluid chamber recess. The first fluid chamber recess and the second fluid chamber recess are each limited in a radially outwards direction by the outer sleeve to form a first fluid chamber and a second fluid chamber. The elastomer body is configured to be substantially undercut-free in an axial direction on its axial end faces. The elastomer body and the cage are configured to be substantially undercut-free in the region of the first fluid chamber recess and the second fluid chamber recess, at least in two predetermined, mutually opposite radial directions.
HYDRAULIC POWERTRAIN COMPONENT MOUNT WITH VARIABLE STIFFNESS
A powertrain component mount includes a housing, a main rubber element, a hydraulic body, a membrane and a valve. The main rubber element has an outer armature, an inner armature and an isolating element coupled to the armatures, the isolating element being formed of a material that is more flexible than the outer armature and the inner armature, wherein the main rubber element defines at least part of a fluid flow path. The hydraulic body supports the outer armature of the main rubber element, defines part of the fluid flow path, a fluid chamber, and part of a control chamber communicated with the fluid flow path. The hydraulic body has a port open to the control chamber. The membrane defines part of the control chamber and the valve has a valve head movable between a first position closing the port and a second position spaced from the port.
LIQUID SEALING BUSH
In a liquid sealing bush, in an outer peripheral surface (13os) of an intermediate tube (13), a main seal protrusion portion (23) extending over an entire length in a circumferential direction and pressed against an inner peripheral surface (11is) of an outer tube (11) is separately provided at each position sandwiching a liquid chamber (15) and an orifice passage (16) from both sides in an axial direction, and in the outer peripheral surface (13os) of the intermediate tube (13), an outer seal protrusion portion (22) extending over the entire length in the circumferential direction and pressed against the inner peripheral surface (11is) of the outer tube (11) is separately provided at each position sandwiched between two main seal protrusion portions (23) in the axial direction and sandwiching the liquid chamber (15) and the orifice passage (16) from both sides in the axial direction, in which, in at least one of two outer seal protrusion portions (22), a recessed portion (24) recessed inward in a radial direction and penetrating in the axial direction is formed in a portion separated from the liquid chamber (15) in the circumferential direction.
HYDRAULIC MOUNT FOR VEHICLE
A hydraulic mount for a vehicle is configured to control and damp the behavior of a motor mounted on a vehicle body. The hydraulic mount includes: an inner pipe; a main rubber molded on an outer circumferential surface of the inner pipe and having an upper front liquid chamber and an upper rear liquid chamber, and a lower front liquid chamber and a lower rear liquid chamber; and an outer pipe fitted to an outer circumferential surface of the main rubber to seal the liquid chambers, wherein the main rubber includes a first flow path connecting the upper front liquid chamber and the lower rear liquid chamber filled with fluid such that the fluid is movable therebetween; and a second flow path connecting the upper rear liquid chamber and the lower front liquid chamber filled with fluid such that the fluid is movable therebetween
BUSH-TYPE HYDRAULIC MOUNT
A bush-type hydraulic mount used for mounting a motor module in an electric vehicle is provided. The bush-type hydraulic mount includes an inner pipe, a middle pipe disposed coaxially with the inner pipe, and a main rubber that is vulcanized between the inner pipe and the middle pipe. An outer pipe surrounds the middle pipe. The main rubber includes a front fluid chamber that is recessed from a surface of the main rubber, a rear fluid chamber adjacent to the front fluid chamber and recessed from the surface of the main rubber, and a bridge that separates the front fluid chamber and the rear fluid chamber to allow fluid to flow between the front fluid chamber and the rear fluid chamber and being deformable by external force.
Hydroelastic device comprising a locking system
The device includes solid force transmission elements including two reinforcements, a damping body, a damping space including a damping chamber, the device being normally in a filling state where the damping space is filled with a damping liquid and may accidentally be in a state of loss of filling, which has an integrated element, specific and proprietary, palliative for the loss of filling, inactive in the state of filling and made active in the state of loss of filling where they bring the hydroelastic device to a state of stiffness of a high level, such element including a locking system including a locking part, integrally rigid, and a deformable load part controlled by the state of the device with respect to filling.
Vibration attenuating fluid mount with partitioned compensator
A vibration attenuating fluid mount with a partitioned compensator includes an inner member, an outer member, a flexible member having a castellated transition between a fluid passageway and at least one operating chamber. A membrane may be disposed in a volume compensator in fluid communication with one or more operating chambers. The inner member and outer member may be connected via a castellated connection, a swaged lock ring, or a split-lock ring.
