A hydraulic bearing includes a supporting bearing, a bearing base, and an annular spring element of elastomeric material interconnecting the supporting base and the bearing base. A working chamber and a compensating chamber are bounded by the supporting bearing and bearing base and filled with damping fluid. A partition having an opening separates the working chamber from the compensating chamber. The opening connects the working chamber and the compensating chamber in a fluid-conducting manner. An annular stop is disposed in the working chamber and is movable relative to the supporting bearing in an axial direction. An inner peripheral edge of the annular stop is received in a receiving portion of the supporting bearing. A ratio of a thickness of the inner peripheral edge in the axial direction and a height of the receiving portion in the axial direction is 0.5 to 1.

Hydraulic bearing

A bearing system for a first vehicle part, e.g., a driver's cab of a truck, on a second vehicle part, e.g., a vehicle frame, the first vehicle part being movable from a first position relative to the second vehicle part into a second position, includes a shaft about which the first vehicle part is rotatable from the first position relative to the second vehicle part into the second position, a first flexible bearing element disposed in a first shaft section of the shaft and a second flexible bearing element disposed in a second shaft section of the shaft. The first vehicle part is supported on the shaft in the first shaft section via a first supporting element and in the second shaft section via the flexible second bearing element. The shaft is supported in its first shaft section on the second vehicle part via the first flexible bearing element and in its second shaft section via a second supporting element.

A hydramount, including a supporting bearing and a bearing member, which are supported on each other by a substantially frustoconical, first elastic spring element made of elastomeric material. The hydramount includes a working chamber and a compensating chamber, which are each filled with hydraulic fluid, are separated from each other by a partition, and are in fluid communication via a first damping opening. The supporting bearing is in the form of an internal, first supporting body, which is encircled by an external, second supporting body, at a radial distance. The first and the second supporting bodies are connected by the first elastic spring element and a second elastic spring element. The first elastic spring element and the second elastic spring element define at least two chambers filled with hydraulic fluid. The chambers are positioned transversely to the axis, substantially in diametric opposition to each other in the radial direction, and are in fluid communication via at least one second damping opening.

A bearing system for an engine-transmission (motor-transmission) unit transversely installed in a vehicle body of a motor vehicle, includes a first bearing element positioned between the engine and the vehicle body, a second bearing element positioned between the engine or the transmission and the vehicle body, and a third bearing element positioned between the transmission and the vehicle body. The second bearing element is formed and positioned without a movable intermediate element at the engine or transmission and vehicle body so that torque forces of the engine-transmission unit, supported by the second bearing element, are introduced into the vehicle body substantially in the vehicle longitudinal direction and so that the second bearing element, in a first domain, which includes small excursions in the vehicle longitudinal direction about the static position of rest at standstill of the engine has a first spring rate, and in a second domain, which adjoins the first domain, and includes larger excursions in the vehicle longitudinal direction, has a second spring rate. The second spring rate is greater than the first spring rate.

A mount for mounting a cab on a vehicle frame includes a first and a second mounting part, one of which is provided on the cab and the other of which is provided on the frame. The mount further includes a vibration damper acting between frame and cab. The first mounting part includes an inner anchoring part and an outer anchoring part that is movable with respect to the inner anchoring part, the outer anchoring part radially enclosing the inner anchoring part, an elastic spring element acting between the inner and the outer anchoring parts, the cab being raiseable with respect to the vehicle frame, e.g., in a swiveling manner, from a driving position into a service position, and being lowerable from the service position into the driving position. In response to raising the cab into the service position, the first and the second mounting parts are separated from each other, and, in response to lowering the cab into the driving position, the first and second mounting parts are reconnected. In the driving position, the first mounting part is accommodated in a receptacle formed on the inner anchoring part. A centering device is provided, which aligns the first mounting part with respect to the second mounting part in response to the cab being lowered into the driving position.

A switchable, hydraulically damping bearing has a supporting bearing and a bearing member that are elastically supported upon one another by a bearing spring made of an elastomeric material. The bearing has a working chamber and a compensating chamber that are arranged consecutively in the direction of vibrations. The chambers are filled with damping fluid. The working chamber and the compensating chamber are delimited by a shared partition on the sides facing each other. The chambers are connected in a fluid-conducting manner by at least one damping conduit provided in the partition. The working chamber is delimited by at least one elastic diaphragm that delimits an air chamber on the side facing away from the working chamber. The air chamber is connected to the environment by a switchable intake valve or a non-return valve, depending on the operating state of a supported engine. The air chamber can be filled with air flowing through the non-return valve when the intake valve is closed and the bearing executes pulling movements, thereby increasing bearing rigidity.

Switchable, hydraulically damping bearing

A hydraulically damped bearing having a first anchoring member ( ) and a second anchoring member ( ) that are arranged in a movable fashion to one another, having a spring element ( ) operating between the first and second anchoring members ( ), and having an operating chamber ( ) filled with a damping fluid and a compensation chamber ( ) separate from the operating chamber ( ) and connected to it via a channel ( ) that is defined by the channel walls and that allows the fluid to pass through. The volume of the operating chamber ( ) changes due to the relative movement of the first and second anchoring members ( ), such that the damping fluid is moved in the channel ( ) between the compensation chamber ( ) and the operating chamber ( ). The operating chamber ( ) and the compensation chamber ( ) are separated by a separating wall ( ) that is impacted on both sides by the damping fluid. This separating wall ( ) is held in position at the second anchoring member ( ) by a separating object ( ), where the separating object ( ) includes at least a first and a second separating object element ( ) which are adjacent in an axial bearing direction. The separating object elements ( ) are braced against each other and form a first radial inner section of the channel wall. A housing section ( ) formed onto the second anchoring member ( ) forms a radially outer section ( ) of the channel wall.

A hydraulic bearing includes a supporting bearing and a bearing member braced against each other by an essentially truncated conical elastic spring element of an elastomeric material. The spring element bounds a working chamber and a compensating chamber filled with damping fluid, these chambers being separated from one another by a dividing wall and being in fluid communication with one another via a damping channel. The elastic spring element has two compression-spring sections radially opposite one another and two push-action-spring segments radially opposite one another and the compression-spring sections. The supporting bearing radially overlaps the elastic spring element in the compression-spring sections, and the elastic spring element and the supporting bearing are interconnected by a radial surface area. The supporting bearing and the elastic spring element are interconnected in the push-action-spring sections by an axial surface area extending essentially parallel to the axis of the hydraulic bearing.

A hydraulic bearing, having a working chamber filled with a damping fluid and a compensating chamber. The chambers are separated from one another by a dividing wall and are in fluid communication with one another via a damping channel, to damp low-frequency vibrations. The damping channel is formed by two subchannels which, in terms of technical function, are arranged in a series connection. The subchannels are arranged axially on both sides of a diaphragm that is capable of vibrating. The diaphragm forms a component of the dividing wall, and the diaphragm is provided with a channel separation and has at least one opening within the channel separation for fluid communication of the subchannels with one another.

A single-thrust bearing for a shock absorber with a columnar journal projecting in the damping direction and which is sealingly surrounded by a flexible, annular-shaped membrane, whereby the membrane is secured in its rim area, which projects radially to the outside, to a supporting bearing and separates two liquid-filled working chambers from each other. The working chambers are defined in the area of the extremities which mutually oppose each other by hollow-conical bearing springs made of a rubber elastic material. The bearing springs are supported in their base area on the supporting bearing and are braced against one another by means of the journal by way of their tips which are turned away from each other.

A hydraulically damping rubber sleeve spring containing two annular parts is disclosed. The parts are assembled axially, and each annular part has an inner support sleeve and an outer support sleeve surrounding the inner one with radial spacing, as well as a spring element made of an elastomeric material which connects the support sleeves. The annular parts are provided with at least two recesses, and are configured and assembled such that the recesses complement one another to form first and second fluid-filled working chambers. The chambers are sealed with respect to the environment and joined to one another, in a manner allowing fluid to pass, by at least one damping passage. The two spring elements of the annular parts are braceable against one another in such a way that the axial and radial spring stiffness can be adjusted separately from one another.
