Definitions
- the present invention relates to an air flap for an air flap arrangement of a vehicle front, an actuator for an air flap, and a system with an air flap and an actuator.
- Air flaps and air flap assemblies in general are known from the prior art.
- DE 10 2016 224 846 A1 shows an air flap system for controlling the entry of air into a motor vehicle.
- the air flap system comprises an actuator, at least one group of air flaps, each of which is arranged pivotably between an open position and a closed position, is acted upon by a spring in a first direction of rotation and can be swiveled by the actuator against the action of the spring in a second direction of rotation opposite to the first direction of rotation.
- an air flap that can be rotated substantially about a vehicle width direction is provided in order to provide an air inlet for an engine compartment
- an air flap is provided which is mounted rotatably about a vehicle width direction in order to be moved from a closed to an open position.
- the present invention relates to the former systems.
- Such an air flap has at least two positions. In a closed position it blocks an air inlet for an engine compartment at the front of the vehicle and in an open position it releases the air inlet.
- the air flap can be rotated from the closed position into the open position by a rotary movement about an axis of rotation by means of an actuator that can be connected to the axis of rotation.
- air that flows against the front of the vehicle during ferry operation does not flow into an engine compartment located behind the front of the vehicle in the longitudinal direction of the vehicle.
- a drag coefficient of the vehicle is reduced compared to an open position, in which the incoming air is directed into the engine compartment to cool an engine.
- the air flap may vibrate unintentionally due to the flow and the tolerance play of the air flap bearings in air flap controls.
- the object of the invention is therefore to provide a system which, among other things, is designed to overcome these disadvantages from the prior art, in particular to provide an air flap which reduces the tolerance play in the drive of the air flaps.
- an air flap for an air flap arrangement of a vehicle front has a front surface and a side surface with a link guide. In a closed position, the air flap blocks an air inlet to the vehicle front through the front surface and, in an open position, releases the air inlet.
- the air flap can be guided by a rotary movement around an axis of rotation by means of a guide in the link guide Driver of an actuator rotatable from the closed position to the open position.
- the link guide arranged on the side surface of the air flap has a taper, so that the link guide and the driver essentially have no play to one another in the area of the taper.
- the taper can also be referred to as a narrowing.
- the taper can extend in a region of a predetermined length between two ends of the link guide that are spaced apart from one another in the longitudinal direction of the vehicle.
- a length of the taper can correspond to the area of the link guide.
- the height of the link guide can decrease compared to the rest of the link guide.
- a dimension, in particular an internal dimension, of the link guide can decrease in the width direction of the link guide.
- the link guide is designed as a through hole in the side surface of the air flap.
- the driver can be fixed in the area of the taper. More precisely, a compressive force can be exerted on the driver by the link guide. Depending on the respective materials of the driver and the side surface of the air flap, this compressive force generates a frictional force of a certain level between the driver and the link guide. The friction force and the pressure force fix the driver in the area of the taper on the link guide of the air flap.
- the tapering of the driver on the air flap means that unwanted vibrations, caused, among other things, by air flowing into the air flap and by a tolerance play in the bearings of air flaps, in particular in intermediate positions of the air flap, which are located between the open and the closed position of the air flap, can be avoided.
- the side surface of the air flap can be designed to be resilient in the area of the taper.
- the air flap is mounted so firmly or without play in the intermediate area of the slotted guide that it counteracts fluttering of the air flap (s) even at high vehicle speeds when the air flap (s) are in intermediate positions can be.
- resilient can mean that the side surface of the air flap, at least in the area of the tapering of the link guide, allows elastic deformation to the extent necessary so that the rigidly designed and consequently essentially non-deforming driver in the link guide can pass the taper .
- the taper in the resilient design, can have a smaller internal dimension than an external dimension of the driver.
- the driver can slide in the link guide into the area of the taper.
- the driver can push the link guide to the side when it has reached the area of the taper and slide through the area of the taper.
- the side surface of the air flap can have a recess in the area of the taper, so that the side surface of the air flap is designed to be resilient in the area of the taper.
- the recess can for example be designed as a through hole.
- the recess is formed in a region which is arranged at a distance from the region of the taper in such a way that a wall is formed between the recess and the taper.
- resilient design can in the present case mean that the side surface of the air flap, at least in the area of the tapering of the link guide, allows elastic deformation to the extent necessary so that the rigidly designed and consequently essentially non-deforming driver in the Link guide the rejuvenation can happen.
- the driver if it is in the area of the taper, can move the wall outward into the recess to press.
- the driver can slide through the area of the taper in the link guide.
- the wall can move from the recess back into the link guide due to the elasticity of a material forming the wall, i.e. it can move back so that the taper has its original dimension again.
- a spring force acting on the driver can be set. It should be noted that a relatively high spring force prevents vibrations in the system more reliably than a comparatively low spring force but also means that the actuator has to apply greater forces in order to move the driver through the area of the taper. Therefore, the spring force should be chosen so that sufficient fixation of the driver on the air flap by the tapering and thus undesired vibrations, caused, among other things, by air flowing into the air flap and by a tolerance play of the bearings of the air flaps, especially in intermediate positions of the air flap, avoided but an actuator that is too large or powerful is not required.
- the link guide can have a first end stop for the driver in a first area adjoining the taper, in which the driver can be arranged in the closed and the open position.
- the link guide can have a second end stop for the driver in a second area adjoining the taper, in which the driver can be arranged in a position in which the air flap is essentially half open.
- the actuator can move the driver into predefined positions in which the actuator is fixed in the link guide.
- the end stops do not necessarily have to be hit. It is conceivable that the air flap regularly moves into an end stop acting on the air flap.
- the link guide can, however, still be open there so as not to be overdetermined or to jam prematurely.
- the second end stop can be arranged further away from the axis of rotation for the driver than the first end stop and the taper can extend from the first to the second end stop. If the taper is between the two end stops, the driver can be fixed over the entire length of the link guide so that the air flap can be moved from the closed to the open position essentially in any position on a path and can be held there essentially free of vibrations .
- the axis of rotation of the air cap can run essentially in the vehicle width direction.
- the rotational movement in order to move the air flap from the closed to the open position can comprise rotating the air flap upwards in the vehicle height direction about the axis of rotation extending in the vehicle width direction.
- the axis of rotation of the air flap can then be arranged at a rear end of the side surface of the air flap in the vehicle longitudinal direction.
- the front side of the air flap can then be a surface that closes off the air flap towards the front in the longitudinal direction of the vehicle, in particular a curved surface.
- Such an air flap can be referred to as being shovel-shaped.
- An actuator with a driver is also provided.
- the driver is designed in which an air flap, in particular the above-described air flap having the taper, arranged on the side surface, can be guided.
- the driver is designed to be resilient.
- the side surface of the air flap can be designed to be resilient at least in the area of the tapering of the link guide.
- driver resilient in relation to the driver can mean that it allows elastic deformation to the extent necessary so that the driver can pass the taper in the link guide.
- the resilient design of the driver enables the driver to be fixed in the link guide, in particular in the area of the taper.
- the actuator has a driver which is guided in the slotted guide arranged on the side surface of the air flap and having the taper.
- the actuator is designed to rotate the air flap from the closed position into the open position and into at least one intermediate position of the air flap located between the closed and the open position by a rotary movement about its axis of rotation by means of the driver guided in the link guide.
- the driver is located in the at least one intermediate position of the air flap in the area of the tapering of the link guide in which the driver and the link guide have essentially no play to one another.
- the front of the vehicle is an area of the vehicle which is arranged in the vehicle longitudinal direction in front of a drive unit of the vehicle, in particular an engine.
- a vehicle can be provided having the vehicle front described above.
- the vehicle can be a motor vehicle, in particular a passenger car.
- the vehicle can have a drive unit, wherein the drive unit can in particular have an internal combustion engine.
- an actuator for an air flap of an air flap arrangement of a vehicle front is provided.
- the air flap has a front surface and a side surface with a driver. In a closed position, the air flap blocks an air inlet to the vehicle front through the front surface and, in an open position, releases the air inlet.
- the actuator can be connected to the air flap by means of a connecting element with a link guide in which the driver can be guided so that the air flap can be rotated from the closed position to the open position by a rotary movement about an axis of rotation.
- the link guide arranged on the connecting element of the actuator has a taper, so that the link guide and the driver essentially have no play to one another in the area of the taper.
- the link guide described above with reference to the air flap can also be provided on the actuator side instead of in the air flap.
- the air flap then has a driver that can be guided in the guide of the actuator.
- driver on the air flap is additionally or alternatively designed to be resilient.
- Fig. 1 shows a schematic perspective view of a conventional one
- FIG. 2 shows a schematic diagram to illustrate a movement path of the
- Air flap from FIG. 1 and a driver of an actuator when moving from a closed to an open position Air flap from FIG. 1 and a driver of an actuator when moving from a closed to an open position.
- Fig. 3 shows a schematic side view of an inventive
- FIG. 1 shows a perspective view of a conventional air flap 1.1.
- FIG. 2 shows a schematic diagram to illustrate a movement path of the air flap 1.1 from FIG. 1 and a conventional driver 1.21 of an actuator 1.2 when the air flap 1.1 is moved from a closed to an open position.
- a Cartesian coordinate system is shown in FIGS. 1 and 2, where X indicates the vehicle longitudinal direction, Y the vehicle width direction and Z the vehicle height direction.
- the air flap 1.1 shown in Figure 1 has a front surface 1.11 and a side surface 1.12 with a link guide 1.13.
- the air flap 1.1 blocks an air inlet of a vehicle front (not shown) through the front surface 1.11 and, in an open position, releases the air inlet.
- the air flap 1.1 is moved from the closed position 3 to the open position by a rotary movement about an axis of rotation 1.14 of the air flap 1.1 running in the vehicle width direction Y by means of a driver 1.21 of an actuator 1.2 that can be guided in the link guide 1.13 4 rotated upwards in vehicle height direction Z.
- a pivot point or a pivot axis 1.22 of the actuator 1.2 running in the vehicle width direction Y is arranged further forward in the vehicle longitudinal direction X relative to a pivot point or the pivot axis 1.14 of the front flap 1.1, so that for the driver 1.21 connected to the axis of rotation 1.22 of the actuator 1.2 results in a tighter or smaller turning radius 1.23 than for the air flap 1.1 having the turning radius 1.18. It is therefore necessary to provide the link guide 1.13 in the side surface 1.12 of the air flap 1.1, which compensates for the difference in length between the two differently sized turning radii 1.18, 1.23, that is, enables the driver 1.21 to move relative to the side surface 1.12 when the air flap 1.1 rotates.
- the air flap 1.1 is controlled with a driver 1.21 of the actuator 1.2, in particular having a servomotor.
- a link guide 1.13 is used on the lever arm of the actuator 1.2 or, as is the case here, on the flap side to compensate for angles or to generate a positional deviation of the two axes 1.14, 1.22.
- the link guide 1.13 for fixing the driver 1.21 has a first end stop 1.16 for the driver 1.21 at one end thereof, in which the driver 1.21 is arranged in the closed and open positions 3, 4.
- the link guide 1.13 for fixing the driver 1.21 has a second end stop 1.17 for the driver 1.21 at its other end, in which the driver 1.21 is arranged in a position 5 in which the air flap 1.1 is essentially half open.
- the second end stop 1.17 for the driver 1.21 is arranged further away from the axis of rotation 1.14 than the first end stop 1.16.
- conventional air flaps such as the air flap 1.1 shown in FIG. 1, often result in undesired vibrations of the air flap 1.1 due to the flow and the tolerance play of the bearings of the air flap 1.1 in the air flap control.
- the invention proposes an air flap 1 shown in FIG.
- the air flap 1 according to the invention is shown according to the embodiment in a schematic side view.
- the air flap 1 has a front surface 11 and a side surface 12 with a link guide 13 arranged on the side surface 12. In a closed position 3 (see FIG. 2), the air flap 1 blocks an air inlet to the front of the vehicle through the front surface 11 and in an open position 4 (see FIG. 2) releases the air inlet.
- the air flap 1 By means of a rotary movement about an axis of rotation 14, which is formed at a rear end of the shovel-shaped air flap 1 in the vehicle longitudinal direction X, the air flap 1 can be rotated from the closed position 3 to the open position 4 by means of a driver 21 of an actuator 2 that can be guided in the link guide 13 .
- the structure of the air flap 1 according to the invention corresponds to the structure of the conventional air flap 1.1 described above with reference to FIGS. 1 and 2.
- the air flap according to the invention has a taper 19.
- the link guide 13 arranged on the side surface 12 of the air flap 1 has the taper 19.
- the taper 19 is dimensioned or designed in such a way that the link guide 13 and the driver 21 have essentially no play to one another in the area of the taper 19.
- the side surface 12 of the air flap 1 is designed to be resilient in the region of the taper 19.
- the side surface 12 of the air flap 1 has a recess 15 in the area of the taper 19, here above the taper 19, so that the side surface 12 of the air flap 1 is resilient in the area of the taper 19.
- a wall 191 is formed between the taper 19 and the recess 15.
- Vehicle width direction Y The rotary movement to move the air flap 1 from the closed to the open position 3, 4 corresponds to a rotary movement described above with reference to FIG Vehicle height direction Z upwards.
- the driver 21 of the actuator 2 is in a first end stop 16 for the driver 21, which is in a
- Vehicle longitudinal direction X is arranged adjacent to the taper 19 area.
- the driver 21 of the actuator 2 now moves or slides in the link guide 13 from the closed to the open position 3, 4 due to the differently sized turning radii 1.18 and 1.23 during the rotational movement for adjusting the air flap 1.
- the driver 21 moves, as indicated by the arrow in Figure 3, from the first end stop 16 in the direction of a second end stop 17, which is formed at an opposite end of the link guide 13, ie the second end stop 17 for the driver 21 is further arranged at a distance from the axis of rotation 14 than the first end stop 16 and the taper 19 extends from the first to the second end stop 16, 17.
- the taper 19 which, as described above, extends from the first to the second end stop 16, 17, is designed in the present case to be resilient, as also described above.
- the driver 21, which is embodied as rigid here, can therefore move or push away the wall 191 formed between the taper 19 and the recess 15 in the direction of the recess 15.
- the wall 191 in turn presses the driver 21 against an opposite inner wall of the link guide 13.
- the driver is thus fixed and the actuator 2 can stop the rotary movement and thus hold the air flap 1 in the intermediate position without unwanted vibrations occurring.
- the driver 21 in the intermediate position of the air flap 1, the driver 21 is located in the area of the taper 19 of the link guide 13, in which the driver 21 and the link guide 13 have essentially no play to one another.
- the driver 21 reaches the second stop 17 and is thus located in a second area adjoining the taper 19, in which the driver 21 is arranged in a position 5 (see FIG. 2) in which the air flap 1 is essentially half open.
- the driver 21 reaches the first stop 16 and again after repeatedly passing the taper 19 is thus located in the first area adjoining the taper 19, in which the driver 21 is arranged in the open position 4.
- the actuator 2 has a driver 21 which is designed to be resilient. In the manner described above, the driver 21 can then be supported on the inner walls of the link guide 13.
- the link guide was described above as being designed on the air flap side. However, it is also conceivable that the link guide is provided on the actuator side and the air flap has a driver 21 analogous to the actuator 2 described above.
- an actuator 2 for an air flap 1 of an air flap arrangement of a vehicle front can also be provided, which actuator can be connected to the air flap 1 by means of a connecting element which has a link guide.
- a driver arranged on the air flap 1 can be guided in the link guide on the actuator side. More precisely, the air flap 1 also has a front surface 11 and a side surface 12 here. Instead of the link guide 13 on the air flap side, however, a driver is now fixed or arranged on the side surface 12 of the air flap 1.
- the air flap 1 In a closed position, the air flap 1 blocks an air inlet to the front of the vehicle through the front surface 11, and in an open position 4 it releases the air inlet.
- the air flap 1 can then be rotated in the manner described above by a rotary movement about the axis of rotation 14 described above from the closed position 4 into the open position 3.
- the link guide arranged on the connecting element of the actuator 2 has a tapered link guide on the air flap side as described above, the link guide on the actuator side and the Air flap-side drivers in the area of the taper have essentially no play to one another.
