Description

The invention relates to a motor vehicle having an actuating device for a sliding door, which closes a door opening in a side wall of the motor vehicle in its closed position and is arranged in its open position in front of a wall opening of the side wall delimiting the door opening, with at least one arranged on the side wall and in the direction the door sliding movements extending guide rail for the sliding door and a running on the guide rail and connected to the sliding door carriage for guiding the sliding door along the guide rail, wherein the actuating device at least one on a side facing away from the sliding door inside the side wall arranged drive unit, connected to the drive unit drive wheel and a flexible and tensionable power transmission member communicating with the drive wheel, which is operatively associated therewith for moving the sliding door, wherein at least the guide rail and the drive wheel are combined to form a mounting module which can be mounted on the side wall and can be handled jointly.

A drive unit in the context of the present invention is to be understood as meaning any unit which contains at least one drive motor, for example an electric motor. Usually, such a drive motor, a transmission and a safety clutch are connected downstream. The term "drive unit" should also refer to such or similar combinations.

A motor vehicle with an actuator for a sliding door of the type mentioned is already out of the DE 198 06 762 A1 known. To simplify the assembly, all arranged before the side wall of the motor vehicle components of the actuator, namely designed as a rope power transmission member, a rope leading pulley, a tensioning device for the rope, connectable to the sliding door carriage and designed as a cable drum drive wheel, together with the guide rail for the sliding door to a fixable to the side wall mounting module summarized. Only the drive unit is arranged alone behind the side wall of the motor vehicle and is in driving connection with the drive wheel arranged in front of the side wall via a drive shaft passing through the side wall. The arranged in front of the side wall and rotatable about a horizontal axis drive wheel and other components of the mounting module are covered by a the visual side of the side wall of the motor vehicle forming and relatively large dimensions having cover.

Also the DE 20 2006 003 901 U1 already describes a motor vehicle with a rope-based drive arrangement for the motorized adjustment of a sliding door movable along a guide rail. The drive assembly is equipped with a drive motor which is coupled with two cable drums.

From the DE 10 2007 028 967 A1 is a particularly compact actuator for a sliding door of a motor vehicle known. The actuating device comprises only a drive motor, a drive wheel and a force transmission member designed as a spreading band.

In the DE 10 2004 028 760 A1 a drive device for a sliding door of a motor vehicle is described. Between a drive motor and a drive means of the drive device, a transmission is provided, which operates dependent on load and signal with different torques on the drive means.

The DE 20 2004 010 985 U1 already describes a anti-trap for an electric sliding door of a motor vehicle. The guided in a guide rail sliding door is driven by a driver and a cable by an electric motor. In addition, the sliding door still has a second electric motor which drives the cable in case of jamming in addition to the first electric motor.

Also in the US 2002/0112404 A1 and the US 6,231,113 B1 Similar controls for sliding doors of motor vehicles are already disclosed.

Against this background, the invention has for its object to provide a motor vehicle with an actuator for a sliding door available, in which the actuator is compact and quick and easy to install. At the same time, the visual appearance of the actuator receiving side wall of the motor vehicle to be optimized without additional effort.

This object is achieved with a motor vehicle according to the features of patent claim 1. The subclaims relate to particularly expedient developments of the invention.

According to the invention, a motor vehicle is provided with an actuating device for a sliding door, in which the side wall has at least one opening into which the drive wheel connected to the guide rail is inserted in such a way that the guide rail on an outside of the side wall facing the sliding door is arranged and that the drive wheel is arranged on the inside of the side wall facing away from the sliding door and connectable to the drive unit. In this way, a very compact actuator for the sliding door of the motor vehicle is provided, which can be quickly and easily arranged on the side wall of the motor vehicle and fixed, for example by a screw, that the guide rail and the drive wheel form a jointly manageable unit. Since the drive wheel is not located in front of the side wall of the motor vehicle as in the aforementioned prior art, but behind the side wall, the dimensions of the cover covering the drive wheel and visible from the outside of the motor vehicle can be significantly minimized. Under certain circumstances, which will be discussed later, it is even possible to completely dispense with such a cover. As a result, the visual appearance of the motor vehicle can be improved without additional effort.

A particularly useful and space-optimized development of the present invention is also created in that the drive wheel has a vertically oriented axis of rotation. This makes it possible to arrange the drive unit with respect to a horizontal plane below or above the drive wheel, so that both components are arranged in a common vertical plane immediately behind the side wall or between the side wall and an adjacent side wall paneling. As a result, the dimensions of the side wall including the side wall paneling can be minimized in the horizontal direction and the size of the adjoining the side wall of the vehicle interior can be optimized.

A further improvement of the visual appearance of the motor vehicle is also achieved in that the arranged on the side wall guide rail completely closes the opening in the wall. Since in such a configuration in addition to the drive wheel and the edge regions of the opening are covered or covered by the guide rail and thus are not visible from the outside of the motor vehicle, can be completely dispensed with the cover already received.

As a result of this complete closing or covering of the opening by the guide rail, the penetration of dirt particles through the opening is reduced into the vehicle interior arranged behind the side wall. A passage of liquid, such as rain or condensation, through the opening, is inventively prevented by a seal is arranged between the guide rail and the opening in the side wall. The liquid-tight seal thus ensures that the drive unit arranged behind the side wall does not come into contact with moisture.

It proves to be particularly appropriate that the dimensions of the aperture in the side wall in the vehicle longitudinal direction are greater than a diameter of the drive wheel and smaller than the dimensions of the guide rail in the vehicle longitudinal direction and that the dimensions of the aperture in the vertical direction is greater than an axial length of the drive wheel and smaller than the dimensions of the guide rail in the vertical direction. As a result, on the one hand the arrangement of the mounting module or the insertion of the drive wheel in the opening allows and at the same time ensures the complete covering or covering the entire opening through the guide rail.

This inventive concept can be supplemented in that the dimensions of the opening in the side wall are formed such that the opening forms a guide and / or a support. During the arrangement of the mounting module on the side wall or during the insertion of the drive wheel into the opening, the opening forms a guide for the drive wheel and thereby facilitates the mounting of the mounting module on the side wall of the motor vehicle. After connecting the drive wheel to the drive unit, the opening serves as a support, in particular when the drive unit is connected exclusively via the drive shaft to the drive wheel and is not additionally fixed to the side wall.

Another advantageous embodiment of the present invention provides that the opening is arranged in a recess extending in the vehicle longitudinal direction and provided for receiving the guide rail. This makes it possible to simultaneously arrange the drive wheel behind the side wall and the guide rail in front of the side wall, wherein the guide rail can be arranged by the arrangement in the recess flush with the adjacent side wall surface.

Another feature of the invention is that the mounting module in addition to the guide rail and the drive wheel, the power transmission element and / or at least one provided for guiding the power transmission member pulley and / or a tensioning device for the power transmission member comprises and that the force transmission member at least one rope and the drive wheel at least one Cable drum has, on which is the rope up and / or unwound. Apart from the drive unit, which is not part of the mounting module, the mounting module thus comprises all components of the actuator and can be handled as a single unit and arranged and fixed to the side wall of the motor vehicle. An operative connection between the drive unit and the drive wheel belonging to the mounting module takes place following the assembly of the mounting module, wherein this operative connection is produced by a plug connection, for example by using a drive shaft and / or output shaft. The flexible power transmission member, which is configured for example as a rope or timing belt, is also part of the mounting module and must not be separately mounted by the inventive design and laboriously threaded through provided in the side wall holes. As a result, on the one hand the assembly effort is significantly reduced and on the other hand, the risk of destruction of the rope or the belt, for example, by abrasion in the field of drilling, significantly reduced.

An advantageous structural embodiment of the invention is also provided in that the drive wheel is fixed to the guide rail and that the drive wheel and extending in the vehicle longitudinal direction guide rail are arranged in the vehicle transverse direction one behind the other. The fixation of the drive wheel on the guide rail can be done by force, form or material connection. However, a releasable fixation, for example, has proved to be particularly advantageous, for example by means of screws, since defective components can easily be exchanged in the event of a malfunction of the actuating device.

The invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in
