Description

The invention relates to an adjusting gear for a switchable freewheel and a switchable freewheel with such an adjusting gear according to the preamble of the independent claims.

In a large number of transmission concepts, the gears to be shifted are shifted with the aid of at least one clutch and at least one synchronization mechanism. In order to be able to engage a gear while driving, the drive motor is first disconnected from the input shaft of the transmission by actuating the clutch. Then the speed of the input shaft is synchronized with the speed of the selected gear. Only then is a positive connection established between the input shaft and the gear wheel.

This process is critical in automated manual transmissions insofar as the drive motor, in particular an internal combustion engine, is disconnected from the input shaft of the transmission during a shifting process. Accordingly, in the decoupled operating state, no power is transmitted via the transmission. What is known as a tractive force interruption occurs, which affects the driver through a longitudinal dynamic oscillation that affects comfort.

In manual transmissions, this process is less critical, since the driver manually initiates the shift process and can adjust to the interruption in tractive power. In automated transmission concepts, the driver is more or less surprised by the shift-related longitudinal dynamic oscillations. This can be clearly felt in automated manual transmissions. In the case of a double clutch transmission, this problem can in principle be solved by the double clutch, since the transmission is divided into two sub-transmissions and the double clutch enables the two sub-transmissions to be blended without interrupting the tractive effort. This cross-fading can also take place under load.

In the case of transmission concepts in electric and hybrid vehicles with more than one gear, the problem can arise that tractive power can be interrupted during the shifting process. In the case of hybrid vehicles, depending on the transmission concept, the combustion engine can be switched on during the shift process to compensate for the interruption in tractive power.

In the case of electric vehicles, a special transmission concept must be provided so that shifting without interruption in traction can be implemented in a multi-speed transmission. One way to implement a power shift is to integrate a clutch in combination with a conventional shift element. In particular, a switchable freewheel can be used for this purpose, but this requires a certain design in order to enable recuperation in the drive train.

From the DE 10 2015 201 403 A1 a backstop and a transfer case with such a backstop are known which has a rotatable inner ring, a stationary outer ring and a cage arranged between the inner ring and the outer ring. Several pairs of rollers are guided through the cage, at least one spring element being arranged between the two rollers of the respective roller pair. In this case, at least one radially outwardly designed cam is arranged on the outer circumferential surface of the inner ring, which cam can engage in a groove formed in the cage. A coupling, that is, a backstop, is achieved by rotating the cage in a circumferential direction.

From the DE 10 2009 051 074 A1 a switchable freewheel is known which has a rotatably mounted housing section with an inner clamping surface. The switchable freewheel also has an inner ring with the clamping ramps facing the clamping surface of the housing section. Clamping bodies arranged in pairs are positioned in the freewheel in a gap between the clamping ramps and the clamping surfaces and are held in their clamping position clamping the housing section in both directions of rotation by a spring force exerted by spring elements. Two switching rings are provided with switching fingers distributed over the circumference, which can be rotated in opposite directions via adjusting means such that all clamping bodies can be released from their clamping position and the rotatability of the housing section can be released simultaneously in both directions of rotation.

The object of the invention is to propose an alternative adjustment mechanism for a switchable freewheel with which it is possible to switch between at least two different switching positions of the switchable freewheel.

According to the invention, this object is achieved by an adjustment gear for actuating a switchable freewheel comprising a shift ring for the rotative adjustment of a cage of the switchable freewheel, with at least one driver being formed on the shift ring, which protrudes in the axial direction over a base surface of the shift ring, the driver being positively engaged in a recess of the cage is added to a rotation of the cage relative to an inner ring or a To enable the outer ring of the switchable freewheel and thus to adjust the switchable freewheel between at least two different switching positions. By actuating the external, preferably electrical, actuator, the switching ring is rotated relative to the inner ring or outer ring of the switchable freewheel. The drivers on the switching ring engage in the cage of the switchable freewheel in order to rotate it relative to the inner ring or the outer ring of the switchable freewheel. In order to keep the switchable freewheel in a switching state, the actuator must always track the position of the cage to the position of the inner ring via the switching ring.

The features listed in the dependent claims allow advantageous improvements and further developments of the adjusting gear specified in the independent claim for a switchable freewheel.

In a preferred embodiment of the invention it is provided that the switching ring is connected to a drive ring in a rotationally fixed manner, with external teeth being formed on the drive ring, via which a rotation of the switching ring relative to the inner ring or outer ring of the switchable freewheel can be controlled. In one embodiment of the switchable freewheel, in which either the inner ring or the outer ring of the freewheel is connected to the housing in a rotationally fixed manner, a simplified form of an adjusting gear can be used. The switching ring is non-rotatably connected to a drive ring, with external toothing being formed on the drive ring, which is in operative connection with a toothing on a gear driven by the electric actuator. In this way, a structurally comparatively simple and inexpensive embodiment of the adjusting gear is possible. Due to the toothing on the drive ring, the switching ring can be made from a comparatively cheap material, in particular a plastic, which further reduces the costs for the adjusting gear.

Alternatively, it is advantageously provided that an external toothing is formed on the switching ring, via which a rotation of the switching ring relative to the inner ring or outer ring of the switchable freewheel can be controlled. External teeth on the switching ring mean that there is no need for an additional component. In this case, however, a higher quality material is necessary for the switching ring in order to transmit the forces of the drive teeth to the switching ring.

In a further preferred embodiment of the adjusting gear, it is provided that an eyelet is formed on the switching ring or on a further component connected non-rotatably to the switching ring, in which a linear actuator engages, the linear actuator engaging in the eyelet in such a way that a linear displacement of the linear actuator a Causes twisting of the switching ring. An eye is formed on the circumference of the switching ring, into which a linear actuator engages. The linear actuator is preferably connected non-rotatably to the housing of the adjustment gear. In addition, defined locking positions can be provided between the linear actuator and the switching ring in order to fix the set switching position of the linear actuator.

For a plurality of applications it is advantageously provided that the adjusting gear is designed as a multi-shaft gear, in particular as a four-shaft gear. This is particularly advantageous when the switchable freewheel is designed as a fully rotary freewheel and both the inner ring and the outer ring of the freewheel are rotatable.

In a preferred embodiment of the variable speed gearbox, the multi-shaft gearbox has two sun gears, two ring gears and two planetary gear sets, the first sun gear being non-rotatably connected to an input shaft and the second sun gear being rotatably mounted on the input shaft and as a switching ring non-rotatably with the cage the switchable freewheel is connected. As a result, the position of the cage relative to the inner ring can be kept continuously even with a fully rotary freewheel, so that simple switching between the different switching positions of the switchable freewheel is possible. The adjusting gear is connected to both a drive shaft and the cage of the switchable freewheel. Both planetary gear sets in the variable speed gear unit have the same gear ratio, so that the resulting speed is identical on both sun gears. Because of this, the speed of the cage is identical to the inner ring of the freewheel. The position of the first ring gear can be rotated relative to the second ring gear by means of an external actuator, in particular an electric adjusting motor. Because of this rotation, a phase offset occurs between the two sun gears, which causes the cage to rotate relative to the inner ring, so that it is possible to switch between the different switching states of the switchable freewheel. This phase offset is kept continuously by the adjusting gear so that the selected switch position of the switchable freewheel is maintained.

It is particularly preferred if the first ring gear is operatively connected to the first planetary gear set in a first toothing plane and the second ring gear is operatively connected to the second planetary gear set in a second toothing plane, the first Planetary gear set and the second planetary gear set are carried by a common planetary gear carrier. A common planet carrier provides a particularly simple way of transmitting the drive torque from the first sun gear to the second sun gear. A phase offset can thus be implemented in a comparatively simple manner.

In a further improvement of the adjustment gear, it is provided that an external toothing is formed on the first ring gear, the external toothing being in operative connection with a toothing of a drive shaft of an electric drive motor in such a way that a control of the adjusting gear by the electric drive motor relatively rotates the second sun gear to the inner ring or outer ring of the switchable freewheel. The external toothing on the first ring gear enables the first ring gear to be rotated relative to the second ring gear, so that the phase adjustment described results. It is thus possible to switch between the different switching positions of the switchable freewheel in an operationally reliable manner.

According to a preferred embodiment of the invention it is provided that the second ring gear is received in the second toothing plane in a non-rotatable manner in a housing of the adjusting gear. In order to support the torque of the planetary carrier and to transmit the speed from the first sun gear to the second sun gear, the second ring gear is fixed in the housing of the adjustment gear so that it cannot rotate.

According to the invention, a switchable freewheel with an outer ring, an inner ring that can be rotated relative to the outer ring and with a cage is proposed, which is arranged between the outer ring and the inner ring. The switchable freewheel comprises at least one pair of clamping bodies connected by a spring, with at least one clamping ramp for a clamping body being formed on one of the rings, in particular on the inner ring, which protrudes in the radial direction in the direction of the cage over the base of the respective ring. An adjusting gear according to the invention is provided in order to rotate the cage relative to the inner ring or relative to the outer ring. If the cage is rotated due to a speed difference between the outer ring and the inner ring, the freewheel can transmit torque in the direction of rotation. In this position, the cage of the switchable freewheel is rotated in the direction of rotation of the outer ring relative to the inner ring. The clamping bodies are positioned in relation to the clamping ramps in such a way that a locking effect results. As a result, the clamp bodies can clamp with the outer ring and transmit a moment. The opposite ramps are blocked at the same time when switching, so that the sprags are brought to a parking position to transfer a torque in the other direction of rotation and rest on the inner ring. When the direction of rotation is reversed, the opposite ramps are enabled and the current ramps are blocked. This means that the switchable freewheel can lock in both directions.

In a preferred embodiment of the invention it is provided that the cage is held or rotated by the adjusting gear in such a way that in a first switching position of the adjusting gear a freewheel function is enabled in the clockwise direction and is blocked in a counterclockwise direction, in a second switching position a freewheeling function is enabled in both directions of rotation is and in a third switching position a free-wheeling function is enabled counterclockwise and is blocked in clockwise direction. The cage is rotated in a first direction by the switching ring. The actuation can take place in several stages depending on the axial displacement, whereby it is possible to switch between the different operating states of the switchable freewheel in a simple manner. Another advantage results from the fact that in the second switching position, in which a freewheeling function is implemented in both directions of rotation, no power loss is generated since the clamping bodies are completely separated from the outer ring.

The various embodiments of the invention mentioned in this application can advantageously be combined with one another, unless stated otherwise in the individual case.

This allows the cage 3 relative to the inner ring 7th be rotated, whereby it can be switched between the different switching positions of the switchable freewheel. The electric drive motor 16 is preferably fixed to the housing 41 of the adjustment gear 13 connected. In addition, latching positions can also be provided in order to move to the switching positions of the electric drive motor 16 to fix.

It is also on the switching ring 30th or one non-rotatably with the switching ring 30th connected actuation ring 35 an eyelet 36 formed, in which an actuator, in particular a linear actuator 37 , preferably directly, intervenes. By a linear displacement of the linear actuator 37 takes place in the eyelet 36 a deflection and thus a rotation of the cage 3 relative to the inner ring 7th . It is thus possible in a simple manner between the different switching positions of the switchable freewheel 1 be switched. The linear actuator 37 can in particular as a spindle drive with an electric drive motor 16 or be designed as a single or multi-stage solenoid.

In 5 is an embodiment for a variable speed gear 13 for adjusting a fully rotary switchable freewheel 1 shown in which both the inner ring 7th as well as the outer ring 2 of the freewheel 1 are rotatably mounted. The variable speed drive 13 is called a multi-shaft gearbox 38 , especially as a four-shaft transmission 39 , executed. The variable speed drive 13 includes two sun gears 19th , 20th , two planetary gear sets 25th , 26th and two ring gears 27 , 28 , with the planetary gear sets 25th , 26th on a common planet carrier 24 arranged are. The variable speed drive 13 is on an input shaft 15th arranged. The first sun gear is in a first gear plane I 19th rotatably with the input shaft 15th connected. Furthermore, the first planetary gear set is in this first gear plane 25th arranged, which with the first sun gear 19th and the first ring gear 27 is engaged. The first ring gear 27 has an external toothing 17th on, in which an adjustment toothing, in particular a worm gear 18th engages to the first ring gear 27 to twist and thus to realize a phase adjustment.

The variable speed drive 13 is with both the input shaft 15th as well as with the cage 3 of the switchable freewheel 1 connected. Both planetary gear sets 25th , 26th in the variable speed gear have the same transmission ratio. Due to the identical translation of the two planetary gear sets, the resulting speed is at the two sun gears 19th , 20th equal. Due to the gear arrangement, the electric drive motor 16 the position of the first ring gear 27 relative to the second ring gear 28 adjusted. Because of this, it is positioned between the two sun wheels 19th , 20th a phase shift occurs at the same speed.
