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 a torque converter is known with arranged on one of the lockup clutch associated torsional vibration damper balancing masses that roll on pendulum rollerways. 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 a robust and low-wear centrifugal pendulum.

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 includes a pendulum roller carrier arranged about a rotation axis and distributed over the circumference arranged on this pendulum rollers. The spherical rollers may be formed, for example, as discs made of sheet metal and round, elliptical, be formed in the form of drops or similar shape. The spherical rollers are captive secured to the pendulum roller carrier. Under the action of centrifugal force of the pendulum roller carrier rotating about the rotation axis, the spherical rollers form a rolling contact by means of a rolling surface with a rolling surface of a pendulum roller conveyor of the pendulum roller carrier. Preferably, the pendulum roller carrier may be formed in two parts or more parts of disc parts such as side panels made of sheet metal, wherein the spherical rollers are accommodated axially between them in individual pendulum spaces separated 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 the action of centrifugal force, spherical rollers shift against the pendulum roller conveyors and shift there for the eradication of torsional vibrations. About the axis of rotation of the pendulum roller carrier located pendulum rollers 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 proposed centrifugal pendulum has between pendulum mass carrier and spherical rollers on a circumferentially effective stop damper device. As a result, the roll angle of the spherical rollers on the pendulum roller tracks is elastically limited, so that hard attacks are avoided. This can lead to a reduction in noise of the centrifugal pendulum and to a longer life of the centrifugal pendulum.

According to an advantageous embodiment of the pendulum roller carrier of a centrifugal pendulum is formed from at least two disc parts, between which the spherical rollers are housed axially in a support section. In this case, the stop damping device may be formed between in the pendulum roller carrier, for example, in both disc parts axially opposite, circumferentially arcuate elongated holes and in the slots axially engaging pin of the spherical rollers. Here, the arcuate design of the slots is designed such that a movement of the spherical rollers along the predetermined runways between the elastic end stops is not hindered. The pins or projections may be surrounded by an elastomeric body, for example an elastomeric ring, which may be open or hat-shaped on both sides. The elastomer body comes into contact with the end walls of the slots in the circumferential direction with the corresponding walls and thus delimits the runway of the spherical rollers elastic. Alternatively or additionally, stop bumps such as elastomeric body, spring elements or the like elastic limit the runway of the rolling elements on the peripheral walls of the slots elastic stops.

To protect the elastomer bodies arranged around the pins, they can be sheathed with a sleeve, for example of hard plastic or metal. The sleeve may be open on both sides or have a hat shape.

According to a further embodiment of a centrifugal pendulum with the pendulum rollers between disk parts receiving spherical roller support the stop damping device may be formed by the spherical rollers are formed from a pin end each forming a pin and a surrounding mass body. The pin passes axially through slots of the disc parts. An elastomer body is arranged between the pin and the mass body. In this way, a stop of the pins is elastically damped on circumferential walls of the elongated holes between the pin and the mass body.

According to a further embodiment, the stopper damping device may be provided between the spherical rollers and the pendulum roller tracks. For this purpose, the stop damping device may be formed from a arranged over the circumference of the spherical rollers, annular elastomer body, wherein the elastomer body rolls over a predetermined roll angle of the spherical rollers against a pendulum roll of the pendulum roller carrier in a groove of the shuttle roller and strikes when exceeding the roll angle on pendulum roller carrier. In this case, the elastomeric body may be guided in a groove of the roller track opposite groove of the spherical roller. Alternatively, the elastomeric body can be completely recessed in the groove and be guided radially over a guide ring made of metal or hard plastic in the opposite grooves.

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 spherical rollers, different pendulum rollerways and / or the like.

According to an advantageous embodiment, at least one contact area between spherical rollers and disk parts may be heat and / or surface treated. For example, corresponding contact areas, for example protrusions of the spherical rollers, pins and / or the areas of the window parts or the entire components located in the support sections - disc parts and / or spherical rollers can be 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.

The disc parts may form in a support portion, in which the spherical rollers are distributed over the circumference, a common for all spherical rollers closed or closed separately for each spherical roller or open, for example by a radially outer gap or recesses in the disc parts cage.

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 is available, so that the torque converter can be made particularly narrow axially. 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 the proposed 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 spherical rollers of the centrifugal pendulum can be arranged at the radial height of the converter 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 spherical roller 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 pendulum roller carrier is designed in several parts. For example, this may be formed from a pendulum rollers axially leading first disc part and a second, the pendulum roller tracks having disc part as guide flanges. The two disc parts can be riveted radially within the spherical rollers after their introduction into a work space formed by the disc parts, for example, riveted.

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 pendulum roller carrier directly or to the hub. Advantageously, the pendulum roller 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.

The downstream centrifugal pendulum 4 in turn, the one after the torsional vibration damper wipes out 13 still remaining torsional vibrations. The torsional vibration damper 13 is radially in Area of the feeder 42 of the turbine wheel 10 between its storage on the transmission input shaft 6 and its belly with the maximum axial extension of the slats 43 saved space.
