Description

The present invention relates to a hydraulic mount according to the preamble of claim 1 and a vehicle with such a hydraulic mount according to claim 15.

For the damping of vibrations of vibratory components of devices, it is known to use bearings which can reduce the transmission of these vibrations at least partially according to amplitude and / or frequency. For this purpose, for example, rubber-metal bearings and hydraulic bearings can be used for the storage of engines in motor vehicles. A rubber-metal bearing represents an arrangement of at least one elastically deformable rubber element between usually two metal elements, which are each fixedly mounted on one of the components or the device, between which the vibrations are to be damped, which is then achieved by the elasticity of the rubber element. In the case of a hydraulic bearing, a working chamber is also formed between the metal elements and the rubber element and filled with a fluid such as a hydraulic fluid, which can reach a compensation chamber of the hydraulic bearing via a throttle channel. Additional damping can be achieved by means of the hydraulic fluid via the design of the throttle channel.

In particular, the hybridization of the drive train, i.e. the combined use of two types of drive, increases the demands on the bearing components, since higher masses and higher forces have to be mounted in a vibration-damping manner.

It is known here that bearing elements with hydraulic damping can relatively effectively eliminate the conflict of objectives between improving the acoustics for the driver and other occupants on the one hand and stimulating the roadway from vibrations on the other. Due to the increasingly higher requirements with regard to the damping of the increasing vibratory masses, however, increasingly longer channel systems of the throttle channel of the hydraulic mounts are sometimes required.

It is also known that double-deck sewers can be used for this purpose. The damping channel runs around the throttle disc at an angle greater than 360 °.

For example, this describes EP 0 354 381 B1 a hydraulically damped engine mount with two fluid-filled chambers, which are hydraulically connected to one another via a multi-spiral overflow channel embedded in an intermediate plate. For the simple production of this intermediate plate and for easy adjustment of the overflow channel length, it is provided that the intermediate plate consists of two cup-shaped sheet metal parts with their bottom surfaces lying opposite one another and with an outwardly curved edge as well as an intermediate flat plate with the same outer diameter, this intermediate plate sealingly into the outer circumference cylindrical bearing housing is used. The cup-shaped sheet metal parts each have a radially inwardly directed opening in the cylindrical section and the flat plate has an axial passage opening in the edge area outside the bottom surfaces, with a circumferential area between the radial and axial opening being sealed off in the upper and lower partial channels thus formed. The two cup-shaped sheet metal parts and the flat plate in between are riveted to one another.

It is an object of the present invention to provide a hydraulic mount of the type described at the outset, the hydraulic damping properties of which can be adjusted. In other words, such a hydraulic mount is to be created, the hydraulic damping properties of which can be changed for different applications and in particular for different vehicles or engines without having to change the design of the hydraulic mount for this purpose. This should preferably be as simple, quick, defined, space-saving and / or error-free as possible. At least one alternative to known hydraulic bearings of this type is to be created.

The object is achieved according to the invention by a hydraulic mount with the features according to claim 1 and by a vehicle with the features according to claim 15. Advantageous further developments are described in the subclaims.

The present invention thus relates to a hydraulic mount with two chambers filled with liquid and with a throttle unit which hydraulically connects the two chambers to one another by means of an overflow channel, the throttle unit having a first throttle plate, a second throttle plate and a separating element which are fixedly connected to one another, wherein the first throttle disk and the separating element form a first channel section of the overflow channel, which is hydraulically connected to the first chamber via a through opening of the first throttle disk, the second throttle disk and the separating element forming a second channel section of the overflow channel, which is connected via a through opening of the second throttle disk is hydraulically connected to the second chamber, and wherein the separating element has at least one first through opening which hydraulically connects the first ring section of the overflow channel to the second ring section of the overflow channel. The first chamber can also be referred to as the working chamber and the second chamber as the compensation chamber.

The hydraulic bearing according to the invention is characterized in that the first throttle plate and / or the second throttle plate has or have a plurality of positioning elements which interact with at least one corresponding positioning element of the separating element in such a way that the separating element is held in a fixed position between the two throttle plates, wherein the positioning elements of the first throttle plate and / or the second throttle plate are designed to hold the separating element in at least two different positions, so that the overflow channel has two different lengths, or vice versa.

In other words, at least one of the two throttle disks and the separating element are designed to be fixedly connected to one another during assembly in at least two different positions or alignments to one another. This can be done by appropriately designed positioning elements such as projections and recesses, as will be described in more detail below. As a result, the position of the first through opening of the separating element can be changed in such a way that the hydraulic fluid can pass through the separating element at a different point between the two channel sections. This leads to two transfer channels of different lengths and thus also to different hydraulic damping properties of the hydraulic mount.

For this purpose, for example, at least two recesses can be provided on the part of at least one of the two throttle disks. The separating element can have a corresponding projection which can alternatively engage in one of the two recesses in the throttle disk. During assembly, the separating element can now be positioned or aligned in two different constellations with respect to the throttle disk, in that the projection of the separating element engages in that of the two recesses of the throttle disk, as corresponds to the desired length of the channel section. As a result, the passage opening of the separating element can be positioned as desired and one of two possible lengths of the overflow channel can be set with respect to the throttle disc. In this arrangement, the separating disk can be fixed by the second throttle disk and then the throttle unit can be mounted in the hydraulic mount.

Conversely, this can also take place in that a projection is provided on one of the two throttle disks which corresponds to at least two recesses in the separating element.

In any case, the throttle unit can be designed as described above and, due to the different fixed positioning of the separating element or its passage opening opposite the two throttle disks or its channel sections during assembly, with regard to the total length of the overflow channel on the hydraulic mount or, for example, on the vehicle in which the hydromount is to be used should be optimized. This can improve the damping properties of the hydraulic mount.

According to the invention, the same components of the throttle unit can be used for different applications, which can reduce the costs of manufacturing the throttle unit or the hydraulic bearing and / or increase the flexibility of use. In particular, this adaptation to the application can take place without structural changes to the throttle unit. This can have a correspondingly cost-reducing effect on the production of e.g. injection-molded parts of the throttle unit, since the same tools can be used.

Possibly. In addition, the arrangement of the two throttle disks with respect to one another can be varied, as a result of which the length of the two channel sections can also be changed. This can further increase the possibilities for variation.

According to one aspect of the invention, the first throttle plate and the second throttle plate each have a plurality of positioning elements, which each interact with at least one corresponding positioning element of the separating element in such a way that the separating element is fixedly positioned between the two throttle plates, or vice versa. This can improve the hold of the separating element with respect to the two throttle disks and, in particular, ensure a more uniform power transmission.

According to a further aspect of the invention, the first throttle plate and / or the second throttle plate has a plurality of positioning elements and the separating element has a plurality of positioning elements. This can increase the hold of the separating element with respect to the two throttle disks improve and in particular ensure a particularly even power transmission.

According to a further aspect of the invention, the positioning elements of the first throttle plate and / or the second throttle plate are designed as projections and the positioning element of the separating element is designed as a recess, or vice versa. This can enable a particularly simple but effective implementation of the aspects of the invention described above. In particular, the formation of projections and / or recesses, e.g. in the case of injection molded parts, can be implemented particularly easily.

According to a further aspect of the invention, the throttle unit is cylindrical and the positioning elements of the first throttle plate and / or the second throttle plate are arranged offset from one another in the circumferential direction. This can make it possible to implement the variable positioning of the separating element relative to at least one of the two throttle disks or relative to both throttle disks.

According to a further aspect of the invention, the positioning elements of the first throttle plate and / or the second throttle plate and the positioning element of the separating element are formed in the radial direction and / or in the direction along the longitudinal axis. In each case or in combination with one another, this can enable a particularly simple but effective implementation of the aspects of the invention described above.

According to a further aspect of the invention, the positioning elements of the first throttle plate and / or the second throttle plate are evenly spaced from one another in the circumferential direction. This can make it possible to implement the variable positioning of the separating element with respect to at least one of the two orifice plates or with respect to both orifice plates, in order to change the length of the overflow channel as significantly as possible.

According to a further aspect of the invention, the overflow channel is designed as an annular channel. This can enable the overflow channel to run as straight as possible in the case of a cylindrical throttle unit, so that the flow of the hydraulic fluid is as laminar as possible and turbulence in the flow of the hydraulic fluid can be avoided or reduced.

According to a further aspect of the invention, the separating element is designed to be positioned offset relative to the first throttle plate and the second throttle plate during assembly by rotation in the circumferential direction. This can make the arrangement of the separating element and thus the change in the length of the overflow channel as simple as possible.

According to a further aspect of the invention, the first channel section and / or the second channel section of the overflow channel is or are multi-helical. In other words, the first channel section and / or the second channel section of the overflow channel runs at least twice around the longitudinal axis. This allows the length of the overflow channel to be increased.

According to a further aspect of the invention, the separating element has at least one second through opening which is designed to hydraulically connect the first ring section of the overflow channel to the second ring section of the overflow channel, and the first throttle disk or the second throttle disk has at least one closure element which is designed is to close the first through-opening or the second through-opening of the separating element in a fluid-tight manner. As a result, the scope for changing the length of the overflow channel can be increased.

According to a further aspect of the invention, the first throttle plate and the second throttle plate are of identical design. This can reduce or keep the manufacturing costs low.

According to a further aspect of the invention, the first throttle plate and the second throttle plate are made of plastic, preferably as injection molded parts. This can reduce or keep the manufacturing costs low.

According to a further aspect of the invention, the separating element, preferably as a separating disk, is made of metal, preferably of steel. This can enable a space-saving and at the same time stable implementation of the separating element. In particular when using throttle disks made of plastic, a metallic separating element, in particular as a steel disk, can lead to an increase in the rigidity of the throttle unit.

The present invention also relates to a vehicle with at least one hydraulic mount as described above. In this way, the properties and advantages of a hydraulic mount according to the invention can be implemented and used in a vehicle.

The above figures are described in cylindrical coordinates with a longitudinal axis X , one to the longitudinal axis X perpendicular radial direction R. and one around the longitudinal axis X circumferential direction U .

1 shows a schematic sectional view of a hydraulic bearing according to the invention 1 . 2 shows a schematic sectional view of a throttle unit according to the invention 2 according to a first exemplary embodiment. 3 shows an exploded view of the 2 .

The hydromount according to the invention 1 is cylindrical and essentially rotationally symmetrical to the longitudinal axis X educated. The hydromount 1 has a housing 10 on, which is along the longitudinal axis X a conical spring element in the upper area 11 in the form of a suspension spring 11 encompasses. At the upper end is the suspension spring 11 with a connector 12th in the form of a peg 12th tied together. Below the suspension spring 11 is a throttle unit 2 inside the case 10 arranged. The suspension spring 11 , the cone 12th and the throttle unit 2 close a first chamber between them 13th of the hydromount 1 a, which is filled with a hydraulic fluid and also as a working chamber 13th can be designated.

Along the longitudinal axis X below the throttle unit 2 is on the edge side within the housing 10 , a bellows 14th arranged, which can spread or expand flexibly downwards. From the throttle unit 2 and the bellows 14th becomes a second chamber 15th enclosed, which is filled with the same hydraulic fluid and also as a compensation chamber 15th can be designated. The suspension spring 11 is formed from an elastomeric material and in particular from rubber and at least on the pin 12th vulcanized. The bellows too 14th is formed from an elastomeric material and in particular from rubber.

An overflow channel 23 the throttle unit 2 connects the working chamber 13th and the compensation chamber 15th hydraulically with each other, so that the hydraulic fluid through the overflow channel 23 the throttle unit 2 from the work chamber 13th into the compensation chamber 15th and vice versa. The overflow channel 23 is essentially annular around the longitudinal axis X designed and can therefore also be used as an annular channel 23 are designated.

The throttle unit 2 points along the longitudinal axis X a first, upper throttle disc 20th and a second, lower throttle plate 21 on, which are designed identically as injection molded parts made of plastic. Between the two throttle discs 20th , 21 becomes a separator 22nd in the form of a steel disc 22nd fixed by the two throttle discs 20th , 21 held. The steel disk 22nd has a recess in the middle 22d on which from a membrane 24 is closed, which also acts as a decoupling membrane 24 can be designated. The decoupling membrane 24 is each from one side of rib elements 20c the first throttle disc 20th and of rib elements 21d the second throttle disc 21 along the longitudinal axis X held slightly mobile.

The first, upper throttle disc 20th has a through opening 20a on, through which the hydraulic fluid from the working chamber 13th into a first, upper channel section 23a of the ring channel 23 can get, which through the U-shaped contour of the first, upper throttle plate 20th and the steel disc 22nd is trained. Through a first through opening 22a the steel disc 22nd can the hydraulic fluid in a second, lower channel section 23b of the ring channel 23 get through the U-shaped contour of the second, lower throttle disc 21 and the steel disc 22nd is trained. Through a passage opening in the second, lower throttle disc 21 the hydraulic fluid can then enter the compensation chamber 15th reach. A flow of hydraulic fluid from the equalization chamber 15th in the working chamber 13th takes place in the opposite direction.

According to the invention, it is provided that the first through opening 22a the steel disc 22nd when assembling the throttle unit 2 at different positions relative to the two orifice plates 20th , 21 arrange and there through the two throttle discs 20th , 21 to be able to hold. This can reduce the length of the ring channel 23 can be set differently. This can be the adjustment of the throttle unit 2 to allow different applications such as different engines, without the components of the throttle unit 2 to have to change. Rather, the change or adaptation of the length of the ring channel 23 simply by positioning the steel disc accordingly differently 22nd and the throttle discs 20th , 21 the throttle unit 2 during assembly to each other.

According to the exemplary embodiments under consideration, the steel disk has for this purpose 22nd several, more precisely two times eight, in the circumferential direction U evenly spaced positioning elements 22c on which on the one hand the edge side as eight semicircular recesses 22c radially outwards and on the other hand approximately radially in the center as eight recesses 22c or through openings in the direction of the longitudinal axis X are trained. Corresponding to this, both throttle disks have 20th , 21 corresponding positioning elements in each case 20b , 21b in the form of two by eight protrusions 20b , 21b on which in the recesses 22c the steel disc 22nd engage and the steel washer 22nd thereby in the circumferential direction U be able to hold positively in position. In the direction of the longitudinal axis X becomes the steel disc 22nd of the two throttle discs 20th , 21 held.

Thus, when assembling the throttle unit 2 or the hydromount 1 eg the second, lower throttle disc 21 arranged on a surface and then the steel disc 22nd in exactly the desired positioning of eight possible positions on the second, lower throttle disc 21 be arranged so that all eight protrusions 21b the second lower throttle disc 21 into the eight recesses 22c the steel disc 22nd intervention. This ensures a corresponding positioning of the first through opening 22a the steel disc 22nd opposite the through opening 21a the second, lower throttle disc 21 so that the length of the second, lower channel section 23b of the ring channel 23 can be set within the eight possible positions.

Then, after the decoupling membrane has been arranged 24 , the first, upper throttle disc 20th like this from above onto the second, lower throttle disc 21 be arranged so that a desired positioning of the through opening 20a the first, upper throttle disc 20th opposite the first through opening 22a the steel disc 22nd can be done. This can reduce the length of the first, upper channel section 23a of the ring channel 23 can be set within the eight possible positions. This results in sixteen different lengths of the ring channel 23 as a whole, which can be adjusted during assembly as described above.

4th shows the throttle unit 2 of the first embodiment in a first positioning of the separating element 22nd from above. 5 shows a perspective view of FIG 4th with a cut out area. In this positioning, the hydraulic fluid passes directly through the through-opening, for example from above 20a the first, upper throttle disc 20th through the first through opening 22a the steel disc 22nd and out through the through opening 21a the second, lower throttle disc 21 . This positioning therefore represents the shortest length of the ring channel 23 represents in which the ring channel 23 the hydraulic fluid does not flow through it at all.

6th shows the throttle unit 2 of the first embodiment in a second positioning of the separating element 22nd from above. 7th shows a perspective view of FIG 6th with a cut out area. In this position, the hydraulic fluid enters, for example, from above through the passage opening 20a the first, upper throttle disc 20th in the first, upper channel section 23a of the ring channel 23 which is also completely in the circumferential direction U is flowed through. At the end of the first, upper section of the canal 23a of the ring channel 23 the hydraulic fluid then passes through the first through opening 22a the steel disc 22nd through and directly through the through opening 21a the second, lower throttle disc 21 out into the compensation chamber 15th . This positioning thus represents the mean length of the ring channel 23 in which the first upper channel section 23a of the ring channel 23 complete and the second, lower channel section 23b of the ring channel 23 the hydraulic fluid does not flow through it at all.

8th shows the throttle unit of the first embodiment in a third positioning of the separating element 22nd from above. 9 shows a perspective view of FIG 8th with a cut out area. In this positioning, the hydraulic fluid also enters, for example from above, through the passage opening 20a the first, upper throttle disc 20th in the first, upper channel section 23a of the ring channel 23 which is also completely in the circumferential direction U is flowed through. At the end of the first, upper section of the canal 23a of the ring channel 23 the hydraulic fluid then passes through the first through opening 22a the steel disc 22nd through into the second, lower channel section 23b of the ring channel 23 which is also completely in the circumferential direction U is flowed through. At the end of the second, lower channel section 23b of the ring channel 23 is then the passage opening 21a the second, lower throttle disc 21 arranged so that the hydraulic fluid there through the passage opening 21a the second, lower throttle disc 21 out into the compensation chamber 15th can flow. This positioning therefore represents the maximum length of the ring channel 23 represents in which both the first, upper channel section 23a of the ring channel 23 as well as the second, lower channel section 23b of the ring channel 23 be completely flowed through by the hydraulic fluid.

10 shows a schematic sectional view of a throttle unit according to the invention 2 according to a second exemplary embodiment. 11 shows the throttle unit 2 of the second embodiment in a first positioning of the separating element 22nd from above.

In this case, both the first, upper throttle disc 20th as well as the second, lower throttle disc 21 two in the circumferential direction U running channel sections 23a , 23b on which in the radial direction R. run parallel to one another and each merge radially into one another at one point, see e.g. 12th , 14th and 15th . This can reduce the design leeway when adjusting the length of the ring channel 23 raise. This also allows a longer ring channel 23 be created in order to be able to change the damping properties further.

12th shows a schematic perspective illustration of the second throttle plate 21 according to a third exemplary embodiment from diagonally above. 13th shows the representation of the 12th with separator 22nd . 14th shows the throttle unit 2 of the third embodiment in a second positioning of the separating element 22nd cut open from above. 15th shows the representation of the 14th without first throttle disc 20th .

In this case, the steel washer 22nd a radially outer first through opening 22a and a radially inwardly offset second through opening 22b on. The radially outer first through opening 22a the steel disc 22nd can the two radially outer channel sections 23a , 23b of the ring channel 23 and the radially inwardly offset second through opening 22b the steel disc 22nd the two radially inner channel sections 23a , 23b of the ring channel 23 connect with each other. At least the second, lower throttle disk has 21 a closure element 21c on, which overlapping with the radially outer first through opening 22a the steel disc 22nd are arranged and this can then close fluid-tight.
