Description

The invention relates to a centrifugal pendulum and equipped with this hydrodynamic torque converter with a arranged around the transmission input shaft housing, an integrated pump in the housing impeller, wherein the housing receives a relation to this rotatably arranged turbine wheel, an effective between the impeller and turbine torque converter lock-up clutch and optionally a torsional vibration damper ,

Centrifugal pendulum are sufficiently known from drive trains of motor vehicles. Here, a support member is rotatably received about an axis of rotation, for example, a crankshaft of an internal combustion engine, a transmission input shaft of a transmission or the like. Pendulum masses distributed over the circumference are arranged on the support part, which are suspended in a plane perpendicular to the axis of rotation with respect to the support part in a pendulum fashion on the support part. Due to this pendulum suspension, the pendulum masses in the centrifugal force field of the rotating support member form a speed-adaptive torsional vibration damper by withdrawing the pendulum mass energy through corresponding deflection of the drive train during torque peaks and feed at torque minima.

For example - as from the WO2014 / 082629 A1 known - be arranged axially between two side parts which form the support member, distributed over the circumference pendulum masses. Alternatively - as from the DE 10 2012 221 949 A1 known - pendulum mass parts be arranged on both sides of the support member. Axially opposite pendulum mass parts are connected by means of connecting means with each other to pendulum masses, wherein the connecting means pass through corresponding recesses of the recessed support part.

A centrifugal pendulum can - as for example with reference to the above-mentioned publications WO2014 / 082629 A1 . DE 10 2012 221 949 A1 disclosed - be provided on a one-mass flywheel, for example, a single-mass flywheel made of sheet metal. For example, from the publications WO2014 / 023303 A1 and DE 10 2013 201 981 A1 known, one or more centrifugal pendulum on a torsional vibration damper, according to the document WO2014 / 114 280 A1 on a clutch disc, according to the document EP 2 600 030 A1 be provided on a hydrodynamic torque converter, on a housing of a friction clutch or at similar locations of the drive train.

Furthermore, hydrodynamic torque converter from drive trains of motor vehicles are known and are preferably arranged between an internal combustion engine and a transmission. In this case, the converter function of the torque converter with torque increase is preferably used to start the motor vehicle by the torque from the housing, which is driven by means of the crankshaft of the internal combustion engine, is passed through the impeller. The impeller thereby drives a turbine wheel, which transmits the torque via an output part under support to a stator for torque increase to a transmission input shaft of the transmission. At higher speeds, a lock-up clutch operatively arranged between impeller and turbine wheel is closed so that the torque is transmitted directly from the housing to the transmission input shaft, bypassing the converter components, thus eliminating the deteriorating efficiency of the converter components at higher speeds.

The internal combustion engines used, for example, 4-cylinder diesel engines, have high rotational irregularities, so that in the housing of the torque converter, one or more torsional vibration dampers are provided, depending on their arrangement with open and / or closed lockup clutch between the housing and the output part or between the turbine wheel and the output part of the torque converter are effective. Here, under a torsional vibration damper in a known manner to understand an arrangement with an input and an output part, which are against the action of a spring device limited against each other rotated. Such torsional vibration dampers may include a plurality of damper stages, which are arranged to each other serially and / or in parallel.

For improved vibration isolation of the torsional vibrations of the internal combustion engine, the use of centrifugal pendulums in the housing of the torque converter is furthermore known, which are effectively integrated in the housing in conjunction with torsional vibration dampers. For example, is from the WO 2010/043194 A1 a hydrodynamic torque converter with a plurality of effective in the open and closed state of the lockup clutch damper assemblies and a centrifugal pendulum, said centrifugal pendulum is connected directly to the turbine wheel. From the DE 198 04 227 A1 is a torque converter with at one of the lockup clutch associated torsional vibration damper arranged balancing masses known to roll on pendulum tracks. The object of the invention is the development of a centrifugal pendulum and a torque converter with a centrifugal pendulum. In particular, object of the invention to provide an improved guidance of the pendulum elements on the shuttle element carrier.

The object is solved by the subject matter of claim 1. The dependent of this or independent claims give advantageous embodiments of the subject matter of claim 1 again.

The proposed centrifugal pendulum contains a pendulum element carrier arranged about a rotation axis and distributed over the circumference arranged on this pendulum rollers.

The pendulum element carrier can be formed from a single disk part designed as a pendulum flange, which accommodates pendulum elements arranged distributed on both sides over the circumference. Axial opposing pendulum elements can be firmly connected. The pendulum element carrier can be formed from two or more disc parts, wherein in each case two disc parts have axially between them pendulum sections, between which are distributed axially and distributed over the circumference pendulum elements.

The pendulum elements may be formed as spherical rollers, which have a pendulum track, with which they roll on the pendulum element carrier and thus perform monofilar pendulum movements relative to the pendulum element carrier. The pendulum elements may be formed as bifilar pendulum masses suspended on the pendulum element carrier, wherein the pendulum masses are suspended by means of two circumferentially spaced pendulum bearings on the pendulum element carrier. The pendulum bearings are designed as complementary to each other formed pendulum tracks of the pendulum masses and the pendulum element carrier on which an arranged between the pendulum tracks of a pendulum bearing rolling elements, for example, a pendulum roller rolls.

The pendulum elements may be formed, for example, as discs made of sheet metal and round, elliptical, be formed in a teardrop or similar shape. The pendulum elements are captive secured to the pendulum element carrier. Under the action of centrifugal force of the pendulum element carrier rotating about the axis of rotation, the pendulum elements form a bearing contact by means of a rolling surface with a rolling surface of a pendulum track of the pendulum element carrier. Preferably, the pendulum element carrier may be formed integrally from a disc flange forming disc parts or in two parts or more parts of disc parts such as side panels made of sheet metal, wherein the pendulum elements are axially separated between them in individual pendulum spaces from each other. Both disc parts are firmly connected to each other, for example, riveted or welded. One or both disc parts are rotationally driven, for example, from a crank or transmission input shaft or in an aggregate, for example, input and / or output side in a clutch disc, a torque converter, a friction clutch, a dual clutch, an electric machine or the like integrated.

Under centrifugal force, the pendulum elements shift against the pendulum tracks and shift there to eradicate torsional vibrations. About the axis of rotation of the pendulum element carrier located pendulum elements are protected in a preferred manner at too low centrifugal force against a radial displacement radially inward. For this purpose, corresponding stops, for example, soft stop buffer, spring elements or the like may be provided.

The centrifugal pendulum is tuned to at least one predetermined order of vibration, for example, a main vibration order of the internal combustion engine. If a cylinder deactivation is provided in the internal combustion engine, the centrifugal pendulum can be tuned to a plurality of oscillation orders, namely to the oscillation order of the full number of cylinders and to the oscillation orders of the internal combustion engine with the other cylinders operated. This can be provided for example by different masses of the pendulum elements or pendulum masses, different raceways or pendulum tracks and / or the like.

In the proposed centrifugal pendulum pendulum elements may be housed axially in a support portion of at least two disc parts and on both sides axially extended projections. These projections in each case form a bearing contact with a slot of a disk part having a pendulum track. This means that the pendulum elements are guided by means of their projections in the slots, wherein the slots are arcuate and both limit the swing angle of the pendulum elements and specify the pendulum track of the pendulum elements.

The projections may be, for example, pin-shaped and have a smaller diameter than an outer circumference of the pendulum elements.

In order to prevent slippage of the pendulum elements on the pendulum tracks, is in the proposed centrifugal pendulum between the pendulum elements and the pendulum tracks in the direction of displacement of the pendulum elements a positive connection intended. The positive connection can be provided as a toothing between pendulum elements and pendulum tracks. The toothing is designed, in particular, as a straight toothing aligned parallel to the axis of rotation of the pendulum elements. Furthermore, a V-shaped toothing can be provided.

In an advantageous embodiment, with pendulum elements arranged axially between two disc elements forming the pendulum element carrier, pendulum tracks can be arranged on an axial projection of a disc part to form the positive connection with the pendulum elements. The disk part forming the axial projection can at the same time serve as a rotary drive part of the centrifugal pendulum. Alternatively, the disk part connected to it by means of rivets, for example, can have the axial shoulder with the pendulum raceways.

According to a further advantageous embodiment of a centrifugal pendulum pendulum tracks which form the positive connection can each be arranged on an arcuate slot of the disc parts.

In order to maintain the positive engagement, especially at low speeds of the pendulum element carrier or standing pendulum element carrier, the pendulum elements can be supported with play radially inward. The game is designed to be smaller than the toothing depth of the positive connection. The support may be formed radially within the pendulum elements by at least one of the two disc parts. For example, an axial projection, for example a cranking of one of the two disk parts or both disk parts, can form the play-related stop with respect to the pendulum elements. For example, embossments and / or material transformations, accumulations of material or the like, for example by means of an extrusion molding process form the play-afflicted stop in one or both disc parts. For example, the play-afflicted stop can be provided between slots in the shuttle element carrier, for example in one or both of these forming disc part and axially engaging in these protrusions of the pendulum elements. In this case, slots and projections may be formed separately for forming the backlash-bearing stops, or the elongated holes and projections forming the positive connection between the pendulum element carrier and the pendulum elements may be used.

According to an advantageous embodiment, several, for example, two pendulum elements may each be arranged between two disc parts. For example, in the case of two pendulum elements three disc parts are provided, which are each axially spaced from each other on a support portion and each receive the axially adjacent pendulum elements separately. Here, a middle disc part may be provided with a material thickness that can accommodate the projections of both pendulum elements. However, it has proved to be advantageous if the projections of axially juxtaposed pendulum elements are formed from a pendulum elements and disc parts cross-pin. In this way, the middle disc part can be formed in the same or reduced material thickness as the other disc parts. It is understood that this also applies to a plurality of disc parts arranged between each two outer disk parts and more than two pendulum elements. The pin can be pressed into corresponding openings of the pendulum elements after joining them in the support section or in other ways with these form friction and / or materially connected. Alternatively, the pin can be introduced in advance into the pendulum elements, wherein the pin is then threaded before joining as riveting the disc parts in the slots.

According to an advantageous embodiment, at least one contact area between pendulum elements and disk parts can be heat and / or surface treated. For example, corresponding contact areas, for example projections of the spherical rollers, pins and / or located in the support sections areas of the disc parts or the entire components - disc parts and / or pendulum elements hardened, preferably surface hardened. Alternatively or additionally, coatings, for example layers of diamond-like carbon (DLC), may be provided on at least one contact area. Alternatively or additionally, a part of the rolling surfaces or all rolling surfaces may be correspondingly heat-treated or surface-treated.

For example, to reduce the contact surfaces between the disc parts and the pendulum elements for the axial guidance of the pendulum elements, frontal contact areas between pendulum elements and disc parts can not be parallel, for example, spherical. Alternatively or additionally, the contact surfaces forming rolling surfaces of the pendulum elements and the disc parts to each other in the axial direction can not be formed in parallel. For example, the projections of the pendulum elements or the pendulum tracks of the disc parts may be formed spherically at the slots.

The pendulum elements and / or guide flanges can be surface-treated or heat-treated in a contact area with one another.

Furthermore, a generation of a bonding layer in the edge region by additional chemical elements may be provided over the base material of the roll or an increase of at least a proportion of these chemical elements by more than 20%, preferably more than 50%.

The contact between the pendulum element and the guide flange can not be formed parallel in the direction of the axis of rotation of the pendulum elements. For example, at least one component forming the abutment contact, for example a protrusion of the pendulum element, can be arched, for example crowned.

For example, for lateral guidance of the pendulum elements, a side surface of the pendulum elements to the guide flange not parallel, for example, be spherical or conical, so that the constructive lateral contact as close as possible in the axis of rotation of the pendulum element and a low friction between the shuttle and guide flange can be achieved.

The proposed hydrodynamic torque converter is operatively disposed about an axis of rotation between a crankshaft of an internal combustion engine and a transmission input shaft of a transmission. The torque converter may comprise a housing, for example a toroidal housing, which is arranged around a transmission input shaft. The housing may be mounted on a Leitradstutzen formed for example in the form of a pipe section and sealed against the outside. The housing may be rotationally driven by the crankshaft, wherein in the housing an impeller may be integrated. For this purpose, can be added to a preformed converter shell fins, for example, hung in the housing and be soldered tight.

By means of a hydraulic fluid stored in the housing, for example ATF, a turbine wheel is driven by the impeller. The turbine wheel is rotationally connected to the transmission input shaft. In that regard, the impeller serves as an input part and the turbine wheel as an output part of the torque converter. Between impeller and turbine, a stator by means of a freewheel housing fixed, for example, be taken on Leitradstutzen.

To bridge the hydrodynamic coupling between impeller and the turbine between a pump and turbine effectively arranged lockup clutch is provided which transmits the torque flow frictionally in the closed state from the housing to the transmission input shaft, in the open state, the hydrodynamic coupling between impeller and turbine turns and in the slipping state the torque is divided into a torque transmitted via the torque converter lock-up clutch and a part-torque transmitted via the hydrodynamic coupling. The converter lockup clutch is preferably effected by changes in the flows or pressures of the fluid held in the housing. The flows of the fluid are controlled from the outside by means of appropriate control devices and can be supplied and removed via openings, for example in the transmission input shaft, gaps between the transmission input shaft and Leitradstutzen and / or the like. The torque converter lockup clutch may be a multi-plate clutch disposed between the housing and the turbine wheel.

The torque converter lockup clutch may be a friction clutch arranged between the housing and the turbine wheel, for example a multi-plate clutch or may be formed from a single friction lining forming a frictional connection with a counter friction surface. The lockup clutch may include an axially displaceable piston having a friction surface that can frictionally engage a counter friction surface. Here, the piston can be rotatably connected to the turbine and form a frictional engagement with a counter friction surface arranged on the housing. Alternatively, the piston can be connected in a rotationally fixed manner to the turbine wheel and form a frictional connection with a counter friction surface of the turbine wheel.

According to an advantageous embodiment, the lockup clutch is disposed between outer peripheries of the impeller and the turbine wheel. As a result, additional components, such as fins of the converter lockup clutch, piston and the like can be saved. Furthermore, by eliminating these components additional axial space available, so that the torque converter can be axially formed particularly narrow. The turbine wheel of the lockup clutch formed in this way is designed to be so stiff that the forces occurring at the lockup clutch at the frictional engagement radially outside the vanes of the turbine wheel can be transmitted. The operation of the lockup clutch takes place in a preferred manner by setting different fluid flows or differential pressures on both sides of the turbine shell. The turbine wheel can be rotatably mounted on the transmission input shaft and axially limited displaceable. For example, the bearing can be provided by means of a bush which seals the transmission input shaft relative to the turbine wheel so that different fluid flows or flow directions or pressure differences for controlling the torque converter lockup clutch can be set between the turbine wheel and impeller on the one hand and the remaining volume of the housing on the other hand.

The torque converter further includes a centrifugal pendulum and optionally a torsional vibration damper. For improved vibration isolation of torsional vibrations, improved protection of the centrifugal pendulum, for improved space utilization and the like Especially in a design of the lockup clutch with radially outside into the turbine and the impeller friction surfaces integrated pendulum masses or pendulum elements of the centrifugal pendulum can be arranged at the radial height of the lockup clutch. As a result, axial space can be saved, for example, by axial overlap of the centrifugal pendulum and the Wandlertorus.

According to an advantageous embodiment of the torque converter, the pendulum element carrier can be accommodated on a hub, for example riveted to it. The hub is rotationally connected to the transmission input shaft and has for this purpose, for example, an inner profile such as internal toothing, which forms a rotational lock with an outer profile such as external toothing of the transmission input shaft.

Contrary to the direction of action of the torque converter from the input part to the output part with the turbine downstream centrifugal pendulum, this can be arranged axially between one of the crankshaft facing wall of the housing and the turbine wheel, ie in geometrical arrangement between the input part and turbine wheel. The hub of the centrifugal pendulum can thereby form a rotational circuit with an end portion of the transmission input shaft and thus form the output part of the torque converter.

In a preferred embodiment, the shuttle element carrier is designed in several parts. For example, this may be formed from a pendulum elements axially leading first disc part and a second, the pendulum tracks having disc part as guide flanges. The two disc parts can be riveted radially within the pendulum elements after their introduction into a working space formed by the disc parts, for example.

In an advantageous embodiment, the first of the two interconnected disc parts is connected to the hub.

An in the effective direction between the turbine wheel and centrifugal pendulum optionally arranged torsional vibration damper has an input part, which is connected to the turbine wheel, for example, riveted. The riveting of this riveting is preferably provided radially within the fins of the turbine wheel. The input part may be stamped and formed from an annular sheet metal part. In this case, the elements of the spring device, for example, short helical or bow springs, may be provided radially on the outside surrounding the sheet metal part. The output part of the torsional vibration damper may be connected to the shuttle element carrier directly or to the hub. Advantageously, the pendulum element carrier and the output part of the torsional vibration damper can be connected together with the hub, for example, riveted.

The hydrodynamic torque converter with lockup clutch, centrifugal pendulum and the optional torsional vibration damper can be designed as a separate unit that is threaded during assembly of the drive train of a motor vehicle or on the transmission input shaft.
