Description

Reset device for a direction indicator of a vehicle, direction indicator and vehicle

The present invention relates to a resetting device for a steering column arm of a vehicle, in particular for resetting one for actuating one

Direction indicator device of a vehicle provided steering column lever. The present invention also relates to a turn signal device with a steering column lever and a reset device for resetting the steering column lever and a vehicle with a turn signal device.

Generic reset devices, especially generic ones

Direction indicator devices - so-called turn signal devices - and associated reset devices for steering column levers, in particular for resetting steering column levers for actuating a direction indicator - so-called turn signal reset devices - are known in principle from the prior art, for example from DE 197 58 288 B4, WO 201 1/006627 A1 or the

WO 2013/092150 A1.

In the usual direction indicator devices known from the prior art, the direction indicator is actuated, i.e. of the "turn signal", usually by means of a steering column lever pivotally mounted about an axis running approximately parallel to the axis of rotation of the steering wheel, which is usually arranged below the steering wheel, so that pivoting of the steering column lever and thus actuation of the direction indicator is possible without to have to take a hand off the steering wheel.

The direction indicators known from the prior art can usually be actuated in at least two different ways:

On the one hand, by briefly tapping or operating the steering column stalk from a neutral starting position to a noticeable resistance, clockwise or counterclockwise, the right or left turn signal can be operated once or repeatedly and so-called "tip flashing" can be effected, whereby the Turn signal flashes as long as the steering column lever is held manually in this position or with a vehicle a comfort function a predetermined number of repetitions has been reached after a single operation.

On the other hand, by overcoming a noticeable latching resistance, the turn signals can be operated continuously and so-called "continuous flashing" can be effected, in which case the turn signals flash until the steering column lever overcomes the latching resistance overcome during operation, this time in the opposite direction its neutral starting position has been put back.

To reset the steering column stalk to the neutral starting position, a reset device connected to the steering column stalk is usually provided, which resets the steering column stalk to the neutral starting position both after just tapping it and after overcoming the latching resistance and "continuously flashing" after the "continuous flashing" usually only takes place when the steering wheel is turned sufficiently counter to the direction in which the steering column lever is actuated.

In addition, the steering column lever can be manually reset by the driver by manually moving the steering column lever back into the neutral starting position against the direction of actuation, possibly with effort and beyond the locking resistance.

In order to avoid that the turn signal device, in particular the

Reset device, is damaged if the driver holds the steering column lever during the actual reset process and thus blocks the reset, which is particularly the case with commercial vehicles and long combinations

Articulated buses and long trucks with several trailers, which occurs frequently and is necessary, especially when turning, to ensure that the turn signal remains switched on until the end of the vehicle or the trailer has taken the new direction of travel, as a rule, most direction indicators indicate an overload device, which usually comprises an overload spring that is preloaded in the event of an overload, ie when the reset is blocked by the driver. If the block is suddenly released because the driver no longer blocks the reset and releases the pitman arm, it is in the overload spring

stored energy suddenly free and the resetting takes place with a significantly higher energy, due to the additional, while blocking the

Reset generated bias in the overload spring than from the unblocked state. The sudden resetting can lead to an abrupt resetting of the components and, as a result, an abrupt impact on corresponding stops or components in the neutral starting position. In particular, reset noise can occur and it can be caused by the sudden

Impact of the components leads to increased wear, which generally has a disadvantageous effect on the service life of the individual components and thus of the reset device.

It is therefore an object of the present invention to provide an alternative resetting device, in particular an improved resetting device, preferably a resetting device which, in particular, enables less noisy resetting and / or in which less wear occurs and / or with which in particular a longer one Lifespan, ie can achieve a higher number of actuation cycles. Another object of the present invention is to provide an alternative turn signal device, in particular an improved turn signal device, and an alternative vehicle, in particular an improved vehicle.

According to the invention, this object is achieved by a reset device, by a direction indicator device and by a vehicle having the features according to the respective independent patent claims. Advantageous embodiments of the invention are the subject of the dependent claims, the description and the figures and are explained in more detail below.

A resetting device according to the invention for a steering column lever of a vehicle, in particular for resetting a steering column lever provided for actuating a direction of travel display device of a vehicle, has one

Actuating axis of rotation rotatably mounted actuating element and a blocking and releasing device. The actuator can be in a neutral

Starting position and is from the neutral starting position in at least a first position, in particular in a first direction indicator position, pivotable about the actuation axis of rotation and the blocking and

Release device is designed to hold the actuating element in the at least one first position and to release it again. The blocking and

Release device comprises a fixedly arranged link with a link contour for guiding the actuating element, a latching device with at least one movably mounted latching element and a slider device which has a slider slidably mounted along a slider axis between a blocking position and a release position. The locking element is along one

The locking element axis can be moved between a locking position and a reset position relative to the link contour, the locking element protruding beyond the link contour in the locking position in such a way that the actuating element can be held in the at least one first direction indicator position. In the reset position, the latching element is displaced such that it only protrudes beyond the link contour so far or no longer that the actuating element is released and can be returned to the neutral starting position along the link contour. If the slide is in the blocking position, the locking element is held in the locking position by the slide device and the locking element is displaced along the

Locking element axis in the direction of the reset position is blocked. If, on the other hand, the slide is in the release position, the locking element is released and can be displaced along the locking element axis in the direction of the reset position.

This configuration according to the invention, in particular the release of the latching element decoupled from the actuating element, enables blocking of a reset of the actuating element in one position, in particular a direction indicator position, without during the resetting process of the other components of the

Reset device worth mentioning to store additional energy in the reset device, in particular without pretensioning a return spring or the like required to reset the actuating element.

As a result, a sudden resetting of the components can be avoided. As a result, reset noise in particular can be reduced and / or avoided. In many cases, wear can also be reduced and in particular a longer service life and / or a higher number of actuation cycles can be achieved. Due to the longer service life or the higher number of actuation cycles achievable, a reset device according to the invention can also be used in

Direction indicators for commercial vehicles, such as buses, in particular city buses and towing vehicles for articulated trains, in particular in

Trigger cam is in the trigger position. In this way, actuation of the reset device can be prevented in a particularly simple manner if the release cam is not in the release position. As a result, the service life of the reset device can be increased considerably, since only one actuation of the

Reset device takes place or can be effected when the trigger cam is in the trigger position.

In a further advantageous embodiment of a reset device according to the present invention, the release cam is in each case only in the release position when the actuation element is in an actuation position, in particular a direction indicator position, and in the idle position when the actuation element is in the neutral starting position.

In a further advantageous embodiment of a reset device according to the present invention, the release cam is held in the link guide by means of a spring device, in particular by means of two at a defined angle to one another and in particular symmetrically to a displacement axis of the

Trigger cam arranged tension springs, which are fixed in particular in a functional installation state with their end facing the steering shaft and / or a steering wheel and are each attached to the trigger cam with their other end. This enables a particularly reliable and thus advantageous resetting of the trigger cam.

The invention is now based on preferred exemplary embodiments and under

Reference to the accompanying drawings explained in more detail.

They show schematically and in principle:

1 shows a section of a first exemplary embodiment of a reset device 100 according to the invention of a direction indicator device according to the invention in a functional installation state in a vehicle according to the invention in an unactuated state in a basic illustration and highly schematic, the

Reset device 100, an elongated, by a not specified here

Actuating axis of rotation rotatably mounted actuating element 10, which from a neutral starting position PO in a first direction indicator position P2 for displaying a direction of travel to the left and a second, not shown here

Direction indicator position to show the direction of travel can be swiveled to the right. The actuating element 10 is designed to be connected to a steering column lever of a vehicle, not shown here, and essentially serves to actuate the steering column lever by a driver on the vehicle

Vehicle display device, and in particular on a not shown here

Direction indicator switch to switch on and off of associated lights, especially turn signal lights.

The direction indicator according to the invention can be operated in at least two different ways:

On the one hand, by briefly tapping or operating the steering column stalk from the neutral starting position PO up to a noticeable resistance in position P1, clockwise or counterclockwise, the right or left turn signal can be operated once or repeatedly and a so-called "tip flashing" are effected, the blinker flashing as long as the steering column lever is held manually in this position P1.

On the other hand, by overcoming a noticeable latching resistance, the turn signals can be operated permanently and so-called "continuous flashing" can be effected, in which case the turn signals flash until the steering column lever overcomes the latching resistance overcome when it is actuated and reaches the

Direction indicator position P2, this time in the opposite direction, has been returned to its neutral starting position in the neutral starting position PO.

According to the invention, the reset device 100 also has a blocking and

Release device which is designed to hold the actuating element 10 in the travel direction display position P2 and to release it again.

In the exemplary embodiment shown in FIG. 1, the actuating element 10 has a pressing element 11 in the form of a roller body 11 formed as a roller, in particular as a cylindrical roller, which counteracts with a defined prestress along a longitudinal axis 13 of the actuating element by means of a pressing spring 12 a backdrop contour 21 of a backdrop 20 of the blocking and release device is pressed and can roll on the backdrop contour 21. The backdrop contour 21, of which in the following figures in particular only the area for a direction indicator to the left (pivoting of the

Actuating element 10, based on the illustration in FIG. 1 upward by actuating a steering column lever downward), is in this

Embodiment in particular V-shaped with an obtuse opening angle, the link contour 21 being arranged such that its opening points away from a steering shaft L of the vehicle which can be rotated about an axis of rotation L.

In addition to the backdrop 20 with the backdrop contour 21, the blocking and

Release device furthermore has a latching device with a latching element 22 movably mounted in the link 20, in particular axially displaceably mounted along a latching element axis, the latching element 22 along the latching element axis between a latching position, which is shown in FIG. 1, and a reset position (cf. 3) is displaceable relative to the backdrop 20, in particular relative to the backdrop contour 21.

The locking element 22 is in particular designed such that it is in the

Detent position, as shown in Fig. 1, protrudes over the link contour 21 such that the actuating element 10 in the associated direction indicator position P2, in this case in the first direction indicator position P2, which one

Direction indicator to the left corresponds, can be held.

To release the actuating element 10 from the travel direction display position P2, the latching element 22 can be shifted into a reset position (cf. can be reset, in particular without a latching resistance from position P2 to position P1 having to be overcome manually by a driver, in particular overpressed.

For an automatic reset of the actuating element 10, the opening angle of the link contour 21 and the pressing force of the pressing element 11 are selected such that, as soon as the latching element 22 is no longer blocked, the

Actuator 1 1 becomes free and automatically returns to the neutral starting position PO due to the applied forces, in particular as a result of the prestress applied by means of the spring 12. Furthermore, the blocking and releasing device according to the invention has one

Slider device, which comprises a slider 23 slidably mounted along a slider axis between a blocking position, which is shown in FIG. 1, and a release position (cf. FIG. 3), which, when in the blocking position, engages the locking element 22 in holds the rest position and a shift of the

Locking element 22 along the locking element axis, based on the illustration in this case to the right, blocked in the direction of a reset position (see FIG. 3).

If, on the other hand, the slide 23 is in the release position, as in FIG. 3, the latching element 22 is released and can be displaced along the latching element axis in the direction of the reset position, in particular by means of the actuating element 10 when it is on the link contour 21 from the direction of travel display position P2 is returned along to the neutral starting position PO.

The slider 23 of the blocking and releasing device of the invention

Resetting device 100 is held in the blocking position by means of a slide spring 24 in the form of a spiral spring 24 in order to ensure that the

To enable the actuating element 10 in the direction indicator position P2, in particular without additional energy expenditure, and thus passively.

The reset device 100 also has a driver 25 coupled to the actuating element 10, which is also rotatably mounted in the reset device 100 and in particular follows the movement of the actuating element 10, which is indicated here in FIG. 1 by the dashed lines, while the solid line symbolize the neutral starting position, d. H. the unactuated state of the turn signal device, which occurs when the actuating element 10 assumes the position PO. If the actuating element 10 is in the position P1, a so-called “tip flashing” is effected and in the position P2 the so-called “continuous flashing”.

The driver 25 is designed as a link guide and has an approximately W-shaped guide groove 26 which is perpendicular to the plane

Actuating axis of rotation runs and in which a release cam 27 with a rotary axis projection 28 can slide rotatably supported. The trigger cam 27 is not only mounted in the driver 25, in particular in its guide groove 26, but is also by means of two tension springs 32A and 32B, which are fixed to the housing G with their end facing the steering shaft of the vehicle 30, in particular by the resulting spring force , held under tension in the driver 25, in particular in its guide groove 26.

If the actuating element 10 is now pivoted about the actuation axis of rotation, for example from the neutral starting position PO into the

Direction indicator position P2, this means that the trigger cam 27 due to the pivoting movement of the driver 25 following the actuating element 10 and the guide groove 26 running therein, in which the rotary axis projection 28 of the trigger cam 27 is mounted and can slide, from which in FIG 1, the idle position, based on the illustration in FIG. 1, is shifted to the right in the direction of the steering shaft 30 into a release position (see FIG. 2).

As a result, the release cam 27 can be brought into engagement with a release projection 31 fastened to the steering shaft 30 when the steering shaft 30 is around it

Rotation axis L is rotated, for example by a steering movement applied by a driver.

Since the release cam 27 has a further projection 29, in particular an engagement projection 29, in addition to the rotary axis projection 28 with which the release cam 27 is guided in the guide groove 26 of the driver 25, the

Trigger cam 27 also by a shift from that shown in Fig. 1

Idle position, based on the illustration to the right into the release position in the direction of the steering shaft 30, can also be brought into engagement with the slide 23, which has a corresponding groove 33 in the area of the release cam 27, into which the engagement projection 29 can engage, see FIG . 2.

Now, as can be clearly seen from FIG. 2, by a rotation of the steering shaft 30 about the axis of rotation L in the direction of the pivoting direction of the actuating element 10, in this case by a steering movement to the right, the triggering projection 31, with which to the right in the Tripping position disengaged trigger cam 27 are engaged. As illustrated in FIG. 3, this causes the trigger cam 27 to rotate counterclockwise about its pivot point, which in this case is formed by the pivot axis projection 28 and defines a cam axis N.

Because the engaging projection 29 has been brought into engagement with the groove 33 of the slide 23 by the disengagement of the trigger cam 27 to the right into the trigger position in the direction of the steering shaft 30, the rotation of the trigger cam 27 in the counterclockwise direction leads to the fact that the Wedge slide 23 against the restoring force of the slide spring 24, based on the illustration in Fig. 3, is moved downward, whereby the locking element 22 is released.

As a result, the latching element 22 can be moved in the direction of the reset position and in particular retracted. This takes place in particular due to the pressing force with which the pressing element 11 of the actuating element 10 is pressed against the link contour 21, which is dimensioned in particular such that the actuating element 10, in particular the pressing element 11, as soon as the latching element 22 is released, on the link contour 21 rolls and the locking element 22 moves in the direction of the reset position.

As a result, the actuating element 10 is released and, in particular without having to overcome the latching resistance, is returned to the neutral starting position PO along the link contour 21.

Resetting the actuating element 10 has the consequence that the driver 25 is also reset. As a result, the axis of rotation projection 28 of the release cam 27 is again shifted to the left, based on the illustration, due to the W-shaped guide groove 26, as a result of which the entire release cam 27 is re-engaged away from the steering shaft 30 and in particular is shifted back into the idle position , in particular in the direction of a displacement axis which extends in the extension of the longitudinal axis of the actuating element 10 when it is in the neutral starting position PO.

As a result, the engagement projection 29 is disengaged again from the groove 33 of the slide 23 and in particular disengaged from the slide 23, as a result of which the slide 23 is released again and as a result of the restoring force of the slide spring 24 again is shifted from the release position shown in FIG. 3 into the blocking position according to FIG. 1 along the slide axis.

If the slide 23 is moved from the release position back into the blocking position, the locking element 22, which also has a wedge surface corresponding to a wedge surface of the slide 23, is consequently, in the exemplary embodiment shown, in particular due to the design of the slide 23 as a wedge slide 23. from the reset position, which is shown in Fig. 3, again in the locking position shown in FIG. 1.

As can be clearly seen from FIGS. 1 to 3, as soon as the reset is triggered, namely when the triggering projection 31 fastened to the steering shaft 30 comes into engagement with the triggering cam 27, the slide 23 from the blocking position, which in the 1 and 2 is shown, in the release position, as shown in Fig. 3, shifted, but without introducing energy into the reset device, in particular without tensioning or biasing a spring or the like.

Rather, only the blocking of the locking element 22 is released. If the actuating element 10 is now held in the direction of travel display position P2 by the driver, this does not prevent rotation of the trigger cam 27 or displacement of the slide 23, but both the trigger cam 27 and the slide 23 can shift completely independently of the actuating element 10, such as in the case of an unblocked reset. In particular, without energy in the

Reset device is stored or the like.

As a result, the actuating element 10 can be reset as soon as the driver releases the actuating element 10 with the same amount of energy as in the case in which the driver has not blocked the reset.

In this way, an abrupt resetting, in particular a kickback of individual components of the resetting device 100, can be avoided. The consequence of this is that the risk of the occurrence of reset noises can be considerably reduced and these can even be partially avoided entirely. Furthermore, the load, in particular the mechanical load on the parts, can be kept considerably lower. which has an advantageous effect on possible material selection and dimensioning of the individual components. Furthermore, with an inventive

Reset device can achieve a longer service life at least in some cases. In the ideal case, even the number of actuation cycles required for commercial vehicles can be achieved and thus a reset device can be provided with which the service life requirements for use in a commercial vehicle can also be met.

Fig. 4 shows a second embodiment of an inventive

Reset device 200, this embodiment being essentially in the design of the slider 23 'and in the design of the locking element 22', as well as with respect to the groove 33 ', which in this case instead of on the side facing away from the steering shaft 30, on the steering shaft facing side of the slider 23 is different.

Due to the aforementioned differences, the one shown in FIG

Embodiment of the rotary axis projection 28, which defines the cam axis N of the release cam 27, arranged on the side facing away from the steering shaft 30 by the slide 23 'and the engagement projection 29 therefor on the side facing the steering shaft 30.

Another difference is that in this case the slide spring 24 is not supported on the housing G in the center in the region of the reset device 200 (cf. reset device 100, FIGS. 1 to 3), but rather on the outer edges.

Correspondingly, the wedge surfaces of slide 23 ″ and locking element 22 ″ are inclined at a complementary angle in comparison to the previous exemplary embodiment. Otherwise, the principle of the resetting device 200 is identical to the resetting device 100 previously described with reference to FIGS. 1 to 3, which is indicated by the same

Reference symbols should be expressed.

Both exemplary embodiments 100 and 200 have in common that the actuation rotational axis of the actuating element 10 in each case, based on a function

Installation state of the reset device in a vehicle, runs parallel to the axis of rotation L of the steering shaft 30. The locking element axis, along which the locking element 22 or 22 'can each be displaced, likewise runs in both exemplary embodiments parallel to the longitudinal axis 13 of the actuating element 10 when it is in the neutral starting position PO.

The latching element 22 or 22 'is in each case elongated in both exemplary embodiments and has a corresponding shoulder which comes to rest on a stop of the latching element recess 20 when the latching element 22 or 22' is in the latching position in order to prevent it that the locking element 22 or 22 'protrudes too far beyond the link contour 21 and thus a reset of the

Actuating element 10 may no longer be ensured.

Both exemplary embodiments also have in common that the slide axis, along which the slide 23 or 23 ′ can be displaced from the blocking position into the release position, runs perpendicular to the locking element axis, the slide axis in both

Embodiments also run in a common plane with the locking element axis and in particular in a plane that is perpendicular to the rotational axis of actuation and in these embodiments also perpendicular to the axis of rotation L of the steering shaft.

In the two previously described exemplary embodiments of reset devices 100, 200 according to the invention, that which is held in a travel direction display position P2 after actuation by means of the blocking and releasing device

Actuating element 10 in a functional installation state

Reset device 100, 200 in a vehicle, as can be clearly seen from FIGS. 1 to 4, are each released again by a steering process and by means of a turning test 31 attached to a steering shaft, in particular by a steering process in a steering direction, which one of the respectively indicated

Direction of travel causes opposite direction of travel. In other words, as in the exemplary embodiments 100, 200 shown, if the actuating element 10 is in the travel direction display position P2 for displaying the travel direction to the left, the reset can be triggered by a steering movement to the right, and vice versa a direction indicator position in which the

Direction of travel is shown to the right, which is indicated by a horizontal axis second half of the reset device reflected below can be realized, can be released by a steering movement to the left.

In some cases it can be advantageous if the slide 23 or 23 'of the

Reset device 100 or 200 for the area of the link contour 21 of the

Reset device 100 or 200, which is assigned to a direction indicator in a first direction of travel, for example the direction of travel to the left, is formed in one piece with the slide which is a direction indicator in the opposite direction of travel, i. H. the direction indicator is assigned to the right.

It can also be advantageous to connect the locking elements to one another or to form them in one piece or in one piece, so that both locking elements are blocked or released at the same time.
