Problems solved by technology

As a result, in the case of hydraulic mountings, it is possible, for example, that vibrations emitted by the engine are transmitted at least substantially undamped to the undercarriage of the motor vehicle, thus making corresponding noises, for example, clearly perceptible in the vehicle interior

Embodiment Construction

[0066] figure 1 A hydraulic mount 2 is shown. The hydraulic mount 2 comprises a load spring 36 in the form of a rubber element. The support spring 36 is conventionally in the form of a hollow body, the top side of the support spring 36 having a cover 38 . Attachment elements (not shown) for securing the engine are typically attached to the cover 38 . In a simple embodiment, the connecting element is a threaded bolt that can be screwed onto the engine. The underside carrying the spring 36 adjoins the partition 8 . The working chamber 4 is formed between the load spring 36 , the cover 38 , and the partition 8 . The working chamber 4 is filled with hydraulic fluid. This fluid is preferably a mixture of oil and water. Adjacently below the partition 8 in the longitudinal direction L is a hollow cylindrical base shell 40 , the inner space of which is divided by a flexible partition 48 . The space enclosed by the partition 8 , the partition body 48 and the base housing 40 form...

Abstract

The invention discloses a linear actuator, a hydraulic bearing, and a motor vehicle with such a hydraulic bearing or linear actuator. The invention relates to an electromagnetic linear actuator (16) with a stator (18) and an armature (20) which can be moved relative to the stator (18). The stator (18) has at least one permanent magnet (22) and at least one coil (24), the stator (18) has a conductive element (26) made of a ferromagnetic material, the conductive element (26) extends over the at least one permanent magnet (22) and / or the at least one coil (26), and the armature (18) forms a yoke (34) made of a ferromagnetic material in the longitudinal direction L for the conductive element (26). The invention further relates to a hydraulic bearing (2) with a support spring (36), a working chamber (4), which is filled with a hydraulic fluid, a compensating chamber (6), a partition (8) which is arranged between the working chamber (4) and the compensating chamber (6), a throttle channel (10) which is formed between the working chamber (4) and the compensating chamber (6) for exchanging hydraulic fluid, and a control membrane (12) which is paired with the partition (8) and which is designed to change a working chamber volume (14) of the working chamber (4). The hydraulic bearing (2) has an electromagnetic linear actuator (16) according to the invention, and the armature (20) is mechanically connected to the control membrane (12). The invention additionally relates to a motor vehicle with such a hydraulic bearing (2).

Description

technical field [0001] The invention relates to a linear actuator having a stator and an armature movable relative to the stator. [0002] The invention also relates to a hydraulic mount having a load spring, a working chamber filled with hydraulic fluid, an equalizing chamber, a partition arranged between the working chamber and the equalizing chamber, a partition formed between the working chamber and the equalizing chamber. A throttle pipe between the equalization chambers and for the exchange of hydraulic fluid, a control diaphragm assigned to the partition and designed as a working chamber volume for changing the working chamber, and having an electromagnetic linear actuator, wherein, The armature of the linear actuator is mechanically connected to the control diaphragm. [0003] The invention also relates to a motor vehicle comprising a frame, an engine, and an engine mount in the form of a hydraulic mount that, by mounting action, creates a connection between the engin...
