Abstract
An actuating arrangement and method for opening and closing a hinged motor vehicle panel utilizes a controllable fluid drive and an uncontrolled fluid drive. The hinged motor vehicle panel is driven during opening from a starting position to a predetermined opening angle by the controlled fluid drive and, after reaching the predetermined angle of opening, is driven into its final position exclusively by the uncontrolled fluid drive.

Actuating arrangement for opening and closing hinged motor vehicle panels comprising a controllable fluid drive and an uncontrolled fluid drive, wherein the hinged motor vehicle panel is driven during opening from a starting position to a predetermined angle of opening by the controlled fluid drive and after reaching the predetermined angle of opening is driven into an end position exclusively by the uncontrolled fluid drive.
An actuating arrangement for opening and closing a hinged panel of a motor vehicle comprising:
- a controlled fluid drive operatively arranged on a body of the motor vehicle to control a movement of the hinged panel;
- and
- an uncontrolled fluid drive operatively arranged on the body of the motor vehicle to control the movement of the hinged panel;
- wherein, during an opening movement, the controlled fluid drive is actuable to move the hinged panel from a starting position to a first predetermined opening angle, after which point, the controllable fluid drive is deactuated, and the hinged panel is moved to an end position by the uncontrolled fluid drive.
An actuating arrangement for closing a hinged panel for a motor vehicle comprising:
- a controlled fluid drive operatively arranged on a body of the motor vehicle to control a movement of the hinged panel;
- and
- an uncontrolled fluid drive operatively arranged on the body of the motor vehicle to control the movement of the hinged panel;
- wherein, during a closing movement, the controlled fluid drive is actuable to move the hinged panel from an end position to a predetermined opening angle, after which point, the controllable fluid drive is deactuated, and the hinged panel is moved by way of its kinetic energy acting against a drive force formed by the uncontrolled fluid drive to the starting position.
A method of opening and closing a hinged panel for a motor vehicle comprising:
- providing a controlled fluid drive operatively arranged on a body of the motor vehicle to control a movement of the hinged panel;
- providing an uncontrolled fluid drive operatively arranged on the body of the motor vehicle to control the movement of the hinged panel;
- actuating the controlled fluid drive during an opening movement to move the hinged panel from a starting position to a first predetermined opening angle;
- deactuating the controllable fluid drive when the first predetermined opening angle is reached;
- and
- moving the hinged panel to an end position by the uncontrolled fluid drive.
A method of closing a hinged panel for a motor vehicle comprising:
- providing a controlled fluid drive operatively arranged on a body of the motor vehicle to control a movement of the hinged panel;
- providing an uncontrolled fluid drive operatively arranged on the body of the motor vehicle to control the movement of the hinged panel;
- actuating the controlled fluid drive during a closing movement to move the hinged panel from an end position to a predetermined opening angle;
- deactuating the controlled fluid drive when the predetermined opening angle is reached;
- and
- moving the hinged panel by way of its kinetic energy acting against a drive force formed by the uncontrolled fluid drive to the starting position.
