Description

Pendelschiebernnaschine

The present invention relates to a controllable, hydraulic

Pendulum slider machine according to the preamble of claim 1.

From DE 44 34 430 C2 a generic controllable, hydraulic pendulum pusher machine with a housing arranged in an inner rotor is known which identifies cylinder-like receptacles. Rotary connected is the inner rotor via so-called pendulum driver with an outer rotor which is mounted in a trained as a control housing bearing. The well-known pendulum pusher machine is able to produce a precisely predefined pressure independent of rotational speed. Is used such a

Pendulum pusher usually for supplying bearings in an internal combustion engine with lubricant.

The present invention deals with the problem for a

Pendulum slider machine of the generic type to provide an improved or at least one alternative embodiment, which is characterized in particular by an increased functionality.

This problem is inventively achieved by the subject matter of

independent claim 1 solved. Advantageous embodiments are

Subject of the dependent claims.

The present invention is based on the general idea of designing a generic pendulum pusher machine such that two different pressure levels can be made available with it and thus a supply of at least two different consumers each with a different pressure level is possible. Thus, for example, a lubricant supply of an internal combustion engine in a motor vehicle with a first pressure level and at the same time a lubricant supply of a further consumer with a second pressure level and / or another medium is possible with the pendulum slide machine according to the invention. For this purpose, in the past it was either necessary to provide two different lubricant pumps, that is pendulum slide machines, or to set the second pressure level, for example via a throttle device. The controllable hydraulic pendulum pusher machine according to the invention in this case has an inner rotor arranged in a housing, which has cylinder-like recesses (grooves). In the

Recesses engage this so-called pendulum driver, which are connected with their respective outer end for rotational drive of an outer rotor through the inner rotor to the outer rotor and together with the

Inner rotor and the outer rotor form variable chambers. The

Pendulum drivers are pivotally mounted both in the recesses of the inner rotor and in corresponding recesses of the outer rotor. In addition, a control for changing the eccentricity between the inner rotor and the outer rotor and thus to change a maximum possible chamber volume may be provided, by means of which the flow rate of the pendulum slide machine is precisely adjustable. It is essential to the invention that the pendulum drivers are each coupled to a piston, which is guided in a respectively associated recess of the inner rotor. In the limited by the recesses and the associated pistons spaces within the inner rotor while another pressure level is adjustable than in the chambers between the inner rotor and the outer rotor, which generates two different pressure levels with the pendulum pusher invention and thereby two different consumers can be supplied , This is with previously known Pendulum pushers not possible and represents a significant improvement in functionality, since now no longer two pendulum pushers or complementary to realize two different pressure levels

Throttle devices are needed, but the two pressure levels can be generated with the pendulum pusher machine according to the invention. This is particularly advantageous in the automotive industry, since there is often required, different units with different

Lubricant pressures to supply, with a space available in modern motor vehicles is usually so low that the provision of two separate pendulum slide machines as lubricant pumps is not possible or difficult. Since the pendulum slide machine according to the invention does not require an increased space requirement compared to generic pendulum slide machines, the pendulum slide machine according to the invention can be used instead of previous pendulum slide machines, but offers the great advantage of being able to provide two different pressure levels. The provision of these two different pressure levels is structurally simple, so that the inventive

Pendulum slide machine produces no or only low additional costs.

In an advantageous development of the solution according to the invention, the individual pendulum drivers and the associated pistons are coupled to each other via a respective roller-shaped joint head and a fork / pincer-shaped joint receiver. Such a joint head and an associated fork / pincer-shaped joint receptacle allow a smooth bend between the pendulum driver and the associated piston, whereby a high ease of movement of the pendulum pusher machine can be achieved. In addition, such rod ends and joint receptacles are able to transmit both compressive forces and tensile forces. Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated

Description of the figures with reference to the drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.

Fig. 1 is a sectional view through a first embodiment of a

shuttle pendulum machine according to the invention,

Referring to FIGS. 1 and 2, a controllable hydraulic pendulum pusher machine 1 according to the invention has a in a housing. 2

arranged inner rotor 3, the cylinder-like, but not round, but rectangular recesses 4 (grooves) has. As can be seen from FIGS. 1 and 2, the inner rotor 3 has in each case six recesses 4, which are arranged in a radial manner. Generally speaking, the number of

Recesses 4, however, be arbitrary. The inner rotor 3 is non-positively and / or positively, in particular rotatably connected to a drive shaft 5. When the housing beyond a bearing 6 is provided in the eccentric to the inner rotor 3, a co-rotating outer rotor 7 is mounted. The outer rotor 7 has a plurality of pivotally mounted in this Pendelmitnehmer 8, which engage in the recesses 4 of the inner rotor 3 for rotational drive of the outer rotor 7 through the inner rotor 3 and form variable chambers 9. During the rotation of the inner rotor 3, the chambers 9 change their volume and thereby provide for a flow, such as a

Lubricant promotion, if the pendulum slide machine 1 as

Lubricant pump or is designed as an oil pump in a motor vehicle. In this case, the pendulum slide machine 1 generates a first pressure level in the chambers 9.

According to the invention, the pendulum drivers 8 are each coupled to a piston 10, which is guided translationally in a respectively associated recess 4 of the inner rotor 3. In through the recesses 4 and the associated Piston 10 limited spaces 1 1 is a different pressure level adjustable than in the chambers 9 between the inner rotor 3 and the outer rotor 7, so that with the pendulum slide machine 1 according to the invention two

generates different pressure levels and thereby two different consumers can be supplied. In general, it is also conceivable that in the spaces 1 1 another medium is pumped than in the chambers 9. According to FIG. 1, the bearing 6 is designed as a rotary valve and accordingly about an axis 12 rotatable. A rotation of the bearing 6 causes a change in the eccentricity between the inner rotor 3 and the outer rotor 7 and thereby a change in the capacity of the pendulum slide machine. 1 Alternatively, the bearing 6, as shown for example in accordance with FIG. 2, may be designed as a sliding slide and move on a guide track 13 in the housing 2. Of course, that can be used as a pivot bearing

formed bearing 6 as shown in FIG. 1 may also be formed as a dome.

In order to enable the smoothest possible operation of the pendulum slide machine 1, the pendulum driver 8 and the associated pistons 10 are coupled to each other via a respective roller-shaped condyle 14 and a fork / pincer-shaped joint receptacle, such a condyle 14 and such a fork / pincer-shaped joint receptacle not are only able to generate tensile and compressive forces, but also to compensate for directional deviations between the piston 10 and the respective associated Pendelmitnehmer 8. The recesses 4 in the inner rotor 3 can have a polygonal or similar cylinder a round cross-section.

In addition, a spring device, not shown, can be provided, which biases the bearing 6 in one direction and thereby predetermines a certain volume of the chambers 9. The pendulum sliding machine 1 proposed according to the invention also represents a considerable improvement with respect to an inner tightness, wherein the pendulum sliding machine 1 according to the invention can be operated quasi as a tandem pump for two different pressure levels and / or media. This is possible in particular by the piston 10 in the recesses 4 of the

Inner rotor 3 below the pendulum driver 8, the constructive way

are formed, that the inner leakage of the fluid from the spaces 1 1 to the chambers 9 is at least minimized. It is of course also possible to promote only via the chamber 9 and the spaces 1 1 a fluid or to provide a corresponding pressure level.

A control of the pendulum pusher machine 1 according to the invention is easily possible by rotating as a pivot bearing formed bearing 6 as shown in FIG. 1 or by shifting the designed as a slide slide bearing 6 as shown in FIG. Of particular advantage, however, would be that with the pendulum slide machine 1 according to the invention two different

Pressure levels can be generated and thereby two different consumers can be supplied, which was not possible with previous pendulum slide machines due to the leak between the rooms 1 1 and the chamber 9. The pendulum pusher machine 1 according to the invention does not require an increased space requirement, so that instead of previous

Pendulum slide machines can be installed.

Subsequent embodiments relate to FIGS. 3 to 5, wherein the

Pendulum slider 1 is referred to here as a rotary valve pump device 100. Further concordant terms and reference signs are listed in the following table and can be used synonymously or replaced by one another and used in FIGS. 1 to 5:

The rotary vane pump device 100 is provided with at least one

Hydraulic circuit (not shown connected), which is used to power an automatic or automated transmission (not shown) of

Motor vehicle (not shown) with a pressure medium is used, in particular with an oil. The transmission has in particular one or more friction clutches which are hydraulically actuated with switching elements and / or the transmission further to be actuated transmission components, for example. Switching elements such

Sliding sleeves or the like. Has. In particular, the transmission as

Double clutch transmission be designed with two friction clutches. The

Friction clutches are especially as wet-running friction clutches

educated. The friction clutches are cooled by the oil. It is conceivable in a transmission and the use of dry clutches, this is dependent on the particular embodiment. The rotary vane pump device 100 is designed as a pendulum vane pump 200. The pendulum slider pump 200 has a housing 300. Within the housing 300 is an outer ring 400

arranged. The rotary vane pump apparatus 100 further includes a

Internal rotor 500, which is rotatably mounted and functionally effective driven by a motor, not shown. The inner rotor 500 can be driven in particular by an electric motor. Alternatively, the inner rotor 500 of a

Drive motor of the motor vehicle are functionally effectively driven. The inner rotor 500 is disposed within the outer ring 400. The outer ring 400 is arranged eccentrically relative to the inner rotor 500 or can be arranged. The outer ring 400 is preferably displaceable or rotatable relative to the inner rotor 500 can be arranged.

The rotary vane pump apparatus 100 further includes a plurality of sliders 600. The sliders 600 are disposed or disposable between the outer ring 400 and the inner rotor 500. The sliders 600 extend between the outer ring 400 and the inner rotor 500. The inner rotor 500 has a plurality of guide seats 700. The guide receptacles 700 extend substantially in the radial direction. Within the guide receptacles 700, the slider 600 are guided. The width of the slider 600 is at least partially adapted to the width of the guide receptacle 700. The sliders 600 are here swinging guided in the guide seats 700. A plurality of first working spaces 800 are bounded by the outer ring 400 and by the inner rotor 500 and by the slides 600.

In Fig. 3, an embodiment of the rotary vane pump device 100 is shown, wherein seven slide 600 and thus seven, first working spaces 800 are provided. In an alternative embodiment, more or less than seven, first working spaces 800 may be provided. The first working spaces 800 are arranged between the inner rotor 500 and the outer ring 400. The sliders 600 define the respective first work spaces 800 that are partially adjacent to one another. The slide 600 and thus the first

Working spaces 800 rotate with the inner rotor 500. The

Guide seats 700 are preferably circumferentially equally spaced. The slides 600 are guided radially displaceably in the guide receptacles 700. The guide receptacles 700 may be formed as slots or holes (not specified). The guide receptacles 700 may be formed in particular as frontally open-edge slots. Further, the slider 600 are formed as pendulum slider 900, wherein the pendulum slider 900 on

Outer ring 400 are pivotally mounted. The pendulum slider 900 are also pivotally mounted in the guide receptacles 700. The pendulum slide 900 each have a head 1000, wherein the head 1000 is pivotally mounted to the outer ring 400. The head 1000 is functionally effective rotatably mounted on the outer ring 400. The head 1000 has a part-cylindrical surface (unspecified) or a cylinder segment surface. The

Pendulum slider 900 are therefore mounted pivotably on the outer ring 400, in particular with the head 1000. The pendulum slider 900 are here formed substantially conical, with a foot area (unspecified) of the pendulum slider 900 corresponding spherical segment surfaces or two, opposite cylinder segment surfaces, so that the

Pendulum slider 900 is pivotally mounted in the guide receptacles 700. The pendulum slide 900 are substantially rigid here.

The outer ring 400 is designed in particular as an outer rotor 1 100, wherein the outer rotor 1 100 is rotatably mounted. The outer rotor 1 100 is rotatably mounted in a holder 1200. The holder 1200 is preferably arranged displaceably together with the outer rotor 1 100, so that the outer rotor 1 100 together with the holder 1200 relative to the inner rotor 500 is displaceable. As a result, the degree of eccentricity of the inner rotor 500 relative to

External rotor 1 100 adjustable. The holder 1200 is here pivotable about a pivot axis 1300, wherein by pivoting the holder 1200 about the pivot axis 1300, the relative position of the outer ring 400 and outer rotor 1 100 to the inner rotor 500 is adjustable. The first working spaces 800 can be flowed through by a pressure medium (not shown); in particular, a pressure medium can flow in and out, in particular as a function thereof

the current position / position of the respective first working space 800 and / or respective positioning of the feed and discharge openings. The first

Workrooms 800 are therefore for pressure change of the pressure medium

usable. With the first working spaces 800, a first hydraulic circuit (not shown) can be supplied. The first hydraulic circuit is used in particular for supply, namely for lubrication and cooling of the friction clutch (s) with the pressure medium, in particular an oil or for lubrication / cooling of other transmission components.

The disadvantages mentioned are now avoided by the

Guide shots 700 and the slider 600 define a second working space 1400, wherein the second working space 1400 of the pressure medium can be flowed through and the second working space 1400 for pressure change and / or promotion of the pressure medium is used.

This has the advantage that a second hydraulic circuit can be supplied with the second working spaces 1400. The first hydraulic circuit can be used in particular as a low-pressure hydraulic circuit for supplying the friction clutches with lubricating oil. The second hydraulic circuit can in particular for the supply of the switching elements of the transmission as

High-pressure hydraulic circuit may be formed. The volume change of the first working chamber 800 is greater than the volume change of the second working chamber 1400 during operation of the rotary vane pump device 100. The pressure change realized by the second working chamber 1400 is greater than the pressure change realized by the first working chamber 800. The size of the second working spaces 1400 is determined essentially by the stroke of the slides 600 and the cross section of the guide receptacles 700. By an appropriate choice of the size of the guide receptacles 700 realized by the second working space 1400 displacement / delivery volume can be determined. The generatable volume flow in the first working space 800 is determined essentially by the size and the eccentricity of the outer ring 400 relative to the inner rotor 500. Since the second working spaces 1400 are provided within the inner rotor 500, the tapped pressure levels / delivery volumes of the second working space 1400 are better adapted to the required pressure levels for supplying the switching elements of the transmission. The first work spaces 800 are completely ready to supply the friction clutch with the pressure medium. The pressure medium serves as a cooling oil / lubricating oil. Upon rotation of the inner rotor 500, the first work spaces 800 and the second work spaces 1400 are periodically increased and decreased. In this way, a specific volume flow in the first and second working spaces 800, 1400 can be generated. The illustrated on the right side of Fig. 3, Here, the first and second work spaces 800 and 1400 have a large volume, and the first and second work spaces 800 and 1400 shown on the left side of FIG. 3 have a small volume since the inner rotor 500 positions close to the outer ring 400 is and thus the slider 600 are deeply inserted into the guide seats 700. The first working spaces 800 are functionally effective, in particular with a cooling oil supply of a

Motor vehicle (not shown) connected. The second working spaces 1400 are each connected in particular to a high-pressure hydraulic circuit for actuating one or more shifting elements of the transmission. The pressure medium for the first working chamber 800 is preferably sucked from a first pressure medium reservoir (not shown) and the

Pressure medium for the second working chamber 1400 is preferably sucked from a second pressure medium reservoir (not shown). The

Displacement volume and therefore the flow rate per revolution resulting from the displacement in the first working space 800 between the inner rotor 500 and the outer ring 400 and the stroke of the slide 600 in the

Guide receptacles 700 and from the displacement in the second working space 1400. The first working spaces 800 are preferably acted upon from the outside (radially) or axially. The first working chambers 800 can be supplied with pressure medium lines through the outer ring 400, not shown, with the pressure medium or the pressure medium can be disposed of via the pressure medium lines. The second working spaces 1400 within the inner rotor 500 can preferably be acted on from the inside and supplied and disposed of via a hollow bearing pin 1500. Alternatively, the second working chambers 1400 can be acted upon axially, in particular if the guide receptacles 700 are open on the front side. However, in the preferred embodiment, the second working spaces 1400 are also substantially radially biased.

In the following, reference may be made to FIGS. 4 and 5: Since the Embodiments similar to FIGS. 4 and 5 essentially become

Matching components provided with the same reference numerals. FIGS. 4 and 5 partially show a rotary vane pump device 1600a and 1600b, respectively.

The rotary vane pump device 1600a or 1600b is referred to as

Pendulum slide pump 1700a and 1700b formed. A housing and a holder are not shown in Fig. 2. The pendulum slide pump 1700a, 1700b has an outer ring 1800, an inner rotor 1900 and several

Slide 2000 on. The inner rotor 1900 in turn has several

Guide shots 2100a (see Fig. 4) or more

Guide seats 2100b (see Fig. 5), wherein the slides 2000 are guided in the corresponding guide seats 2100a or 2100b. The

Guide seats 2100a (see Fig. 4) are formed as slots (unspecified). The guide seats 2100a are designed as frontally open-edge slots. The cross section of the guide receptacles 2100a is in particular substantially rectangular. The guide seats 2100b (see Fig. 5) are formed as holes (not specified). The

Guide seats 2100b are axially closed in the inner rotor 1900

educated. The guide seats 2100b are axial or frontal

closed trained. The cross section of the guide receptacles 2100b is in particular round, substantially circular.

The outer ring 1800 is preferably formed as an outer rotor 2700. The outer rotor 2700 has an outer circumferential surface 2800, wherein the

Outer rotor 2700 with the outer peripheral surface 2800 rotatable in one

corresponding holder (not shown, but see Fig. 3) is mounted.

The slides 2000 are designed as pendulum slide 2200, wherein the

Pendulum slide 2200 are pivotally mounted on the outer rotor 2700. The Pendulum slides 2200 are not rigid. The pendulum slides 2200 have a piston 2300a, 2300b, the piston 2300a, 2300b being guided in the guide receptacle 2100a, 2100b. The cross section of the piston 2300a, 2300b is adapted to the cross section of the guide receptacles 2100a, 2100b or corresponds to the cross section of the guide receptacles 2100a, 2100b. The pendulum slide 2200 also each have a pendulum piston rod 2400, wherein the pendulum piston rod 2400 is pivotally mounted on the piston 2300a, 2300b. The pendulum piston rod 2400 is also functionally effective rotatably mounted on the outer ring 1800. The pendulum piston rod 2400 has in each case a head 2500, wherein the head 2500 is mounted in a bearing receptacle 2600 in the outer ring 1800. The bearing receptacle 2600 is open to unspecified inner circumferential surface of the outer ring 1800. The outer ring 1800 is arranged eccentrically relative to the inner rotor 1900. The

Rotary vane pumping device 1600a or 1600b has a plurality of working spaces 2900. A total of seven pendulum slide 2200 and thus seven, first work spaces 2900 are provided. The first working spaces 2900 are bounded by the outer ring 1800, the inner rotor 1900 and the slides 2000. The first working space 2900 can be traversed by a pressure medium. The first working space 2900 can be used to change the pressure of the pressure medium. The first working space 2900 is connected to a first hydraulic circuit of a

Automatic transmission (not shown) connectable. The first working spaces 2900 can be supplied with pressure medium via pressure lines, not shown, and disposed of.

The connections for the introduction and forwarding of the pressure medium can, for example, also be arranged axially relative to the first working space 2900. The disadvantages mentioned are now avoided by the

Guide shots 2100a, 2100b and the slide 2000 a second

Workspace 3000 limit, with the second working space 3000 of the Pressure medium can be flowed through and the second working space 3000 for

Pressure change and / or promotion of the pressure medium is used.

The pressure change realized with the aid of the second working space 3000 is preferably greater than the pressure change realized by the first working space 2900. The volume change of the first working chamber 2900 is greater than the change in volume of the second working chamber 3000 during the rotation of the inner rotor 1900 relative to the outer ring 1800. The first

Working space 2900 may in particular be connected to a low-pressure hydraulic circuit of the transmission. The second working space 3000 may be connected to a high-pressure hydraulic circuit for actuating at least one switching element of the transmission.

As already described in the embodiment shown in FIG. 3, the outer ring 1800 can be arranged to be displaceable relative to the inner rotor 1900. As a result, the flow rate of the first working chamber 2900 and the second working chamber 3000 is adjustable. The change in volume during a rotation of the inner rotor of the first working chambers 2900 and the second working chambers 3000 is dependent on the eccentricity of the inner rotor 1900 relative to the outer ring 1800. In the embodiment shown in FIG. 4, the pistons 2300a as

Rectangular piston formed. In the embodiment shown in FIG. 5, the pistons 2300b are designed as round pistons.

A leakage between the high pressure area of the second working space 3000 and the low pressure area of the first working space 2900 can in particular by the double rotatable mounting of the pendulum slide 22 and the

Pendulum piston rod 2400 in combination with pistons 2300a, 2300b can be reduced or minimized. The embodiment with round piston in Fig. 5 has the advantage that the drag torque is reduced. The frontal sealing of the first Work spaces 2900 preferably takes place in that the non-illustrated, frontal pump housing with a high axial force

be pressed. As a result of the guidance of the pistons 2300a, 2300b within the inner rotor 1900, as shown in FIG. 5, the second working space 3000 is already delimited on the front side by the inner rotor 1900. As a result, no high axial prestressing is required when pressing the end-side pump housing. The advantage of using a pendulum vane pump 200, 1700a, 1700b (see Figures 3 to 5) is that it can be aspirated from two separate pressure medium reservoirs. The pendulum slides 900, 2200 are pivotally mounted in the outer rotor 1 100, 2700. The mechanical friction within the

Rotary vane pump device 100, 1600a, 1600b is reduced by the design as a pendulum vane pump 200, 1700a, 1700b. As a result, the proportion of drive energy is minimized, which for driving the

Rotary vane pump device 100, 1600a, 1600b or the

Pendulum slider pump 200, 1700a, 1700b is used. The

Rotary vane pump devices 100 and 1600a, 1600b can also be realized as a vane cell pump (not shown) in an alternative embodiment. The trained as a wing slide are not connected to the outer ring. The outer ring is not co-rotating relative to the inner rotor. The wings are guided radially in the guide receptacles. The seal of the first

Working spaces takes place in that the wings are possibly pressed with a sliding shoe or the like. On the inner peripheral surface of the outer ring. In this case, the first working space and the second working space are preferably connected to one another. The pressure from the displacement from the outer first

Working space is directed under the wings to push the wings against the outer ring when starting the inner rotor, thus creating a seal between the wings and the outer ring. With the help of the rotary vane pump device according to the invention can now vzw. different separate volume flows are generated. On the one hand for the cooling / lubrication of transmission and / or

Coupling components can be realized in particular high flow rates with low pressures, and on the other hand for the

Adjustment / actuation of switching elements low volume flows can be realized at high pressures. In the illustrated here preferred

Embodiment of the rotary vane pump devices according to FIGS. 3 to 5, the first working spaces for the realization of the cooling oil volume flow and the second working spaces for the realization of the volume flow for actuating the switching elements are used here in particular for geometric reasons. It is also conceivable that, for example, in another application, a high pressure with a high volume flow and a low pressure at a lower flow rate is requested, so then a

High pressure hydraulic circuit over the first work spaces and a

Low-pressure hydraulic circuit via the second working spaces would be supplied. This depends on the particular application and the specific embodiment of the rotary vane pump device or its connection to respective other hydraulic components or hydraulic circuits.

Generally, the invention according to FIGS. 3 to 5 relates to a
