Description

The invention relates to a closing unit for a Flap, in particular a front or tailgate of a Motor vehicle with at least two hinges around one Swivel axis between an open and a closed Position of a a drive motor and in particular a Have coupling and a gear arranged thereon Drive is movable.

In such a closing unit for a front or tailgate of a motor vehicle, it is known that the closing unit comprises an electric motor and a transmission connected to the electric motor. The output shaft of the transmission is directly connected to a member of one of the hinges, so that with the actuation of the drive motor, the hinge member and thus the flap are moved. A disadvantage of this device is the driving of the flap over a single hinge, since the weight of the flap to be moved lead to twisting of the flap with an associated tilting. This must be used as a drive motor, a motor with a correspondingly large power to provide sufficient power to move the flap even when tilting. Such electric motors require a relatively large amount of installation space. Furthermore, these electric motors are characterized by a large power consumption, which significantly burden the electrical system of the motor vehicle. In addition, the moments occurring due to the unilateral force application lead to increased wear of the hinges.
The object of the invention is to provide a clamping unit of the type mentioned, which avoids these disadvantages and requires only small driving forces for moving the flap in a simple, low installation space requiring structure.

The object is achieved in that two Hinges each one pivotable about the pivot axis Have actuator and the actuators through Transmission elements of a single drive movable are drivable.

The arrangement of the transmission elements allows a Joint movement drive of the two hinges by one single drive, which in turn is also a symmetrical Force entry allowed. Due to the symmetrical force input become a twisting of the flap and thereby caused Moments avoided. As a result, lower forces to Moving the flap necessary, so that a drive motor with lower power can be used. In addition to the lower Size and the lower cost of such a drive motor The lower power consumption leads to a reduced Load on the power grid, which is especially when used in a motor vehicle is advantageous.

Furthermore, the structure of the closing unit allows a universal use, independent of the type of hinges is. The hinges can be both single-jointed as well Be multi-joint hinges.

By arranging each of a gas spring on the hinges, the movement of the flap in the opening direction is supported. The gas springs are mainly used to balance the weight of the flap.
The drive motor of the closing unit has a compact design when it forms a structural unit with the coupling. Thus, the assembly is pre-assembled, which simplifies the installation of the clamping unit.

The use of an electromechanical coupling has proved to be particularly reliable. This type of coupling allows the use of a switch, by the operation of the closing unit is activated by the coupling of the drive motor to the transmission is made. When the clutch is not closed, the flap can be moved manually.
To determine the angular velocity and the end positions of the flap, the transmission has an angle sensor. From the change in the angular velocity of the flap, in particular a delay, suggests the presence of obstacles. In these cases, the movement of the flap by the closing unit is stopped immediately or the flap is moved back by reversing the drive direction to the initial position. The reversal of the drive direction can be done by changing the direction of rotation of the drive motor or by switching the gearbox.

To allow a manual stop of the closing unit is the closing unit with the switch or another button connected. This allows the movement of the flap in front of the Interrupt the occurrence of an obstacle.

Both the switch for activating the closing unit and the switch to stop can by means of electrical lines or on the principle of a remote control in a separate Keypad, for example in a key, over a Wireless connection to be connected to the clamping unit.

In an advantageous embodiment is on each actuator a arranged radially to the pivot axis aligned rope sector, The souls of two Bowden cables are guided over its sector circumference are, each rope sector, each with a Zugende the Bowden cables is connected and the Bowden cables with their other ends one of the drive rotatably driven cable drum attached are.

But it can also be on each actuator an approximately radially to Be arranged pivot axis aligned pivot lever, wherein at each pivot lever at a radial distance to the pivot axis each one end of the Bowden cables is attached and the Bowden cables with its other ends rotatable on one of the drive drivable cable drum are attached.

The arrangement of the Bowden cables on the cable drum and the Rope sectors or the pivot levers causes, depending on from the direction of rotation of the cable drum, the rope sectors or Swivel lever pivoted in one or the other direction become. Due to the connection with the hinges, these are in both directions for moving the flap pivot. Due to the adaptable length of Bowden cables in conjunction with the free Laying is characterized by such a closing unit great flexibility. The drive with drive motor, Clutch, gearbox and the cable drum can be used in any Spaced from the hinges. That allows one Arrangement of the drive motor in places with sufficient space without having to change existing designs. The Closing unit can therefore be adapted to the most diverse Adjust operating conditions. In addition, the rope sectors or Swivel lever and the Bowden cables simply constructed components, resulting in a particularly cost-closing unit results.

Moving the rope sectors through the Bowden cables is designed in a simple way, if at the two perimeter of the Rope sectors each one end of a Bowden cable is attached and the souls of the Bowden cables in opposite directions over the rope sectors are guided.

The rope sectors have at their sector scope one Bowden cables, in particular the soul, receiving contour. Thereby is a safe guidance of the Bowden cables on the rope sectors guaranteed. The contour is particularly easy when it consists of two extending on the sector periphery grooves, wherein each Bowden cable is picked up by a groove.

The Bowden cables can be combined in a rope sector in misalign a direction when a train end of a Bowden cable a first circumferential end of the cable sector is fastened while the shell in the region of the second circumferential end of the rope sector a stationary component, preferably the body in a Motor vehicle, is arranged. The train end of the other Bowden cable is in the area of the first perimeter of the rope sector on the component and the sheath on the second circumferential end of Rope sector is arranged. Claim in this embodiment the Bowden cables have very little installation space.

The at the ends of the Shaft arranged gears pivot the teeth sectors, which the pivoting movement to the actuators of the hinges transfer. The use of gears and toothed sectors On the one hand allows the transmission of larger forces and Moments. On the other hand, the closing unit at lower to transferring forces and moments are executed smaller, so that less space is required.

Assembly of the tooth sectors on the hinges is avoided if the tooth sectors are integrally formed with the actuators. Due to the simple structure of the dental sectors, the extra effort is negligible.
A small design of the tooth sectors is achieved with a configuration in which the tooth sectors have at their periphery a tooth profile whose teeth are directed radially outward.

A protection of the tooth profiles and the gears against In contrast, damage is achieved with toothed sectors whose teeth directed radially inward, so that the gears from. Scope of the dental sectors are absorbed and covered.

In addition to driving the teeth sectors has a single shaft the drive of each tooth sector by means of its own Well proven. Especially required for repair work this embodiment a lower cost.
