Description

The The invention relates to an adjusting device for pivoting operation a vehicle component, such as a door, a flap or a lid according to claim 1.

The pivoting operation of a vehicle spoiler or an Airbrake element is usually carried out by means of an electric drive in conjunction with gear, rack or threaded rod gears, as it is known from DE 103 48 285 A1 is known. In addition, the use of hydraulic systems is known, with the help of which louvers on the vehicle tailgate are speed-dependent actuated. Furthermore, from the EP 1693285 A2 a rear-side spoiler for a motor vehicle is known, which has a spring-biased folding and sliding system. These known adjusting devices for vehicle components are complex with a correspondingly large space and high weight.

From the other DE 10 2004 040 747 A1 is known as an actuator pneumatic muscle is known, which has a pressure hose which can be filled with a pressurized fluid, thereby reducing its length and correspondingly results in an adjusting movement of a hose end provided attachment shock. From the DE 197 05 414 C1 Another pneumatic actuator is known by means of which a movable body part of a motor vehicle can be opened. From the DE 10 2004 029 167 A1 is a Sitzverstellvorrichtung known in which a pneumatic linear actuator is operatively connected to a rotary drive. Upon actuation of the linear actuator with a pressure, the actuator contracts in the axial direction, whereby the rotary drive is rotated. From the DE 202 17 805 U1 a device for lifting a hood is known, which has a contractible by supplying compressed air pneumatic muscle.

The The object of the present invention is an adjusting device for a pivoting operation of a vehicle component ready to provide, in a simple way the pivoting operation allows the vehicle component.

The The object is solved by the features of claim 1. Preferred embodiments of the invention are in the subclaims disclosed. According to the patent claim 1, the adjusting device a linearly adjustable in a direction of motion transmission element. The motion transmission element is provided with a control section provided, which cooperates with a guide element. The guide member or the motion transmitting member is motion-coupled with the vehicle part. In a linear Longitudinal movement or translational movement becomes the motion transmission element with its control section moved along the guide element, whereby a rotation of the guide element or the Motion transmission element results. Because of the above said movement coupling is this rotational movement of the guide element / Motion transmission element transmitted to the vehicle component. The inventively reduced number of components for movement transmission allows a space-saving compact design with correspondingly low complexity the geometrically simple components and reduced weight, where large forces are generated.

Of the Control section of the motion transmission element can in the direction of movement helical or helical with a given pitch angle or any variable Be executed slope profile. The size of the Lead angle of the control section determines the gear ratio provided by the motion transmitting member. For a compact design of the actuator is a correspondingly large transmission ratio advantageous, in which already a slight linear displacement the motion transmitting member is a sufficiently large Swing actuation of the vehicle component allows. In a variable slope profile of the force or torque curve be adjusted as needed.

In In a preferred embodiment, the control section of the motion transmission member be a rotary wedge, the helically wound with its two gradient surfaces is. When moving the rotary wedge in the direction of movement, the Guide element along the slope surfaces, whereby the motion transmission element around his Longitudinal axis turns.

For a simple and space-saving motion coupling of Motion transmission element with the vehicle component can the vehicle component rotatably on the motion transmission element to sit.

Prefers the vehicle component is adjustable only in its pivoting direction, but not in the direction of movement of the motion transmitting member. The vehicle component therefore sits against rotation on the motion transmission element. However, the motion transmitting member is longitudinal arranged adjustable relative to the vehicle component.

The motion transmission element can by means of a linear actuator, such as a elektri driven linear drive. Preferably, however, as a linear actuator is a pneumatic muscle, with the motion transmission element is adjustable in its direction of movement in a technically simple manner. The pneumatic muscle can contract under pressure by means of air or other fluid, whereby the movement transfer element is moved from its initial position to its actuated position.

For a simple reset operation to its original position the motion transmission element can be an energy storage element, about a return spring, be assigned, which is the motion transmission element returns to its initial position after the adjusting movement.

Advantageous it is when the vehicle part depending on vehicle parameters swivel-actuated in different sizes of rotation angles is. The setting of such different sized rotation angle the vehicle component can be in a simple control technology by several series-connected pneumatic muscles or by variable ones Operating pressure can be realized. The series connected Pneumatic muscles can be via pressure lines be controlled with a control unit. By optional Driving one or more of the pneumatic muscles may be in control engineering easy way the displacement of the motion transmission element can be varied with a correspondingly varying angle of rotation of the Vehicle component.

following is an embodiment of the invention with reference to the accompanying Figures described.

It demonstrate:

1 in an enlarged perspective partial view of the adjusting device for a pivoting operation of a rear-side air guide element;

2 in a perspective overall view extending in the vehicle transverse direction actuator; and

3 in a sectional view of the actuator.

In the 1 is an enlarged perspective view of the actuator for folding up a on a pivotable support lever 1 attached air guide element 2 shown. The merely indicated air guide 2 is here together with the adjusting device on a vehicle rear 4 intended. Like from the 2 shows, is the air guide 2 over a total of two lateral support levers 1 mounted on the actuator. Between the two support levers 1 are pneumatic actuators in series, described later as actuators 3 . 5 provided, of which the muscle 5 via a pivot bearing 7 with a rod-shaped motion transmission element 9 connected is. The two muscles 3 . 5 are in a pipe 10 arranged, located between the two support levers 1 extends.

The motion transmission element 9 Here is an example of a rotary wedge with a through a guide bush 11 guided guide section 13 and a control section 15 at the free end of the rotary wedge 9 , The guide section 13 according to the 1 a flat rectangular profile and is displaceable in the vehicle transverse direction y in the guide bushing 11 stored and rotatably connected to this. The guide bush 11 is in turn according to the 3 via a plain bearing 17 in a frontal housing wall 19 an actuator housing 20 stored while the support arm 1 of the air guide element 2 rotationally fixed over the guide bush 11 on the guide section 13 of the rotary wedge 9 sitting.

The guide bush 11 points into the 1 and 3 on its right side one outside the case 20 arranged ring collar 21 on. Axial between the collar 21 the guide bush 11 as well as the frontal housing wall 19 sits the support lever 1 over in the 3 indicated connections 22 rotatably on the guide bush 11 , In contrast, between the outer end face of the annular collar 21 the guide bush and thereof axially spaced trunnions 23 of the rotary wedge 9 return springs 25 interposed, which is the rotary wedge 9 in the direction of in the 1 pretensioning the starting position shown.

Inside the case 20 the adjusting device is a here only schematically illustrated, two-piece designed guide element 27 provided, this example a guide pin 28 and an opposite support 29 having. The guide pin 28 and the support 29 are in sliding contact with opposite pitch surfaces 31 of the control section 15 , The control section 15 of the rotary wedge 9 is bent helically with its pitch surfaces with a predetermined pitch angle in the vehicle transverse direction y.

Subsequently, the pivoting operation of the air guide element 2 described: Depending on vehicle parameters can be in the 2 shown control unit 33 via pressure lines 34 the pneumatic muscles 3 . 5 apply pressure. When pressurized, the pneumatic muscles contract 3 . 5 that the rotary wedge 9 pull over a shift length I ₁ in the direction of movement I. With the linear displacement of the rotation wedge 9 in the direction of movement I, the control section slides 15 with its opposite slope surfaces 31 along the guide pin 28 or the Auflagers 29 , whereby the in the direction of movement I shifting rotary wedge 9 a pivoting movement II is imposed. The pivoting movement II of the rotary wedge 9 is over the guide bush 11 on the support arm 1 of the air guide element 2 transfer. Through the pivot bearing 7 is guaranteed that the rotary wedge 9 with swing control II no torque on the pneumatic muscle 5 transfers.

Simultaneously with the linear displacement of the rotary wedge 9 in the direction of movement I are the return springs 25 biased. After the waste of compressed air into the pneumatic muscle 3 . 5 and the resulting relaxation of the muscles 3 . 5 cause the two return springs 25 the return of the rotary wedge 9 into his starting position. The parameters for influencing the translational and rotational movements I, II are in particular the pitch angle of the two helically shaped pitch surfaces 31 and the shift length I ₁ .

In the 2 is the actuator over its entire length with the two series-connected pneumatic muscles 3 . 5 shown. The pneumatic muscles 3 . 5 are dimensioned in different lengths and by a control device 33 depending on different vehicle parameters via pressure lines 34 controllable. By using the two series-connected pneumatic muscles 3 . 5 are different sized displacement paths I and thus different rotation angle of the support lever 1 adjustable. So stands the controller 33 with sole control of the pneumatic muscle 3 or the pneumatic muscle 5 as well as combined control of both pneumatic muscles 3 and 5 a total of 3 control options open, each with different resulting displacement paths I.
