Abstract

Drive arrangement for a sliding door leaf 1 of a vehicle, comprises a rod 3 engaged by a pneumatic or hydraulic drive 10 by means of a drive joint 11. The rod is guided at one end by means of a support joint 4 and at the other end by means of a connecting joint 9 mounted directly or indirectly on the door leaf. The support joint is connected to a guide 5, 6 whereby its path of movement lies in a plane which is normal or approximately normal to the direction of sliding movement of the door leaf. <IMAGE>

Description

SPECIFICATION Improvements in or relating to sliding doors The invention relates to a drive arrangement for sliding door wings or pivotal sliding door wings of vehicle doors, comprising a rod which is engaged by a pneumatic or hydraulic drive via a drive joint and which is guided at one end by means of a support joint and at the other end by means of a connecting joint which is mounted on the door leaf or on a structural component movable lengthwise with the door leaf.
It is known to effect opening of the door wing of pivoted or sliding doors with the aid of a pneumatic drive. In this case the piston engages directly with the door wing. With a very wide door wing the piston must have a corresspondingly long stroke and in consequence the cylinder of the pneumatic drive must have an appropriate length and the space requirement is therefore large.
Constructions are also known in which stepup gearing is provided between the pneumatic drive and the door wing drive in order to reduce the stroke of the drive cylinder. In one of these solutions a rod stationarily mounted at one end is moved to and fro by means of a pneumatic drive and at the other end is articulated the door wing, for example with the aid of a slide block, which slides to and fro on a vertical guide rod fixedly arranged on the door wing. It is also known in such a door wing moved with the aid of a pendulous rod to provide the rod end remote from the stationary bearing with a longitudinal slot in which slides a pin arranged on the door wing.
Both embodiments have the disadvantage that the door wing tends to flutter during travel because the movable components arranged at the end of the rod can only be guided with substantial play in order to ensure easy running of the sliding door movement.
A drive arrangement is also known in which a rod suspended in pendulous fashion from a stationary bearing has a telescopically extensible end piece which is pivotally connected with the door wing. This construction has the advantage that in both end positions of the door only those forces can be transmitted which (assuming a practically friction less telescopic guidance) can only be effective normally to the axis of the telescopic rod. This subjects the door leaf to substantial forces whose vertical components must be taken up by the elements provided for the guidance of the door leaf and in many cases lead to lifting of the door wing.As is known the forces required to move the door leaf increase substantially in the region of the door closing position of the door leaf because in this region the forces for pressing the door seals and also the forces required for running into the main lock of the door mechanism must be applied.
In addition, the door speed at the end of the closing process is in most cases so low that the kinetic energy stored in the door wing barely assists the closure process. Because of the frictional losses in the telescope the efficiency of the drive is reduced with respect to a direct drive.
The object of the invention is to provide a door drive which, particularly in the closed end position, causes primarily horizontally directed forces to act on the door leaf and which is characterised by good mechanical efficiency.
According to the invention this is achieved in that the support joint is connected to a guide, e.g. a control arm, rod, link or the like, whereby its path of movement lies in a plane which is normal or approximately normal to the main direction of sliding movement of the door wing.
The invention will now be further described by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a side view of part of one embodiment of door assembly according to the invention; Figure 2 is a corresponding part-sectional end view; Figure 3 is a side view of part of a second embodiment of door assembly according to the invention, and Figure 4 is a corresponding part-sectional end view.
The door wing 1, illustrated in the closed end position, has at one corner thereof a fixed bracket 2 to which is pivoted a rod 3. This is connected by means of a support joint 4 with a triangular guide 5 whose pivot pin 6 is journalled in a bearing block 7 secured to the side wall of the vehicle. Part of the joint 4 is formed from a pivot element 8 journalled in the triangular guide 5. The other end of the rod 3 is pivoted to the bracket 2 by means of a ball joint 9.
The pneumatic drive 10, comprising cylinder, piston and piston rod, engages the rod 3 by means of a drive joint 11 the position of which is preferably so selected that in the closed end position of the door the axis of the support pivot 1 2 of the piston and cylinder drive lies horizontally.
The door guide is generally designated 1 3.
It determines the progress of the door movement. The main direction of the latter is substantially parallel to the longitudinal axis of the vehicle and as a general rule only has a component of movement perpendicular thereto at the start of the opening movement and at the end of the closing movement. According to the drawing the main direction of the opening and closing movement of the door leaf 1 corresponds to the longitudinal direction of the carrier rail 1 3'.
As can be seen from the drawing the force of the drive on the guide rod 3 is effective in the joints 4 and 9 whereby in the support joint 4 there can be transmitted only forces acting in one plane which is determined by the triangular guide axis 6 and the support joint 4. If the connecting line between the drive joint 11 and the support joint 1 2 is horizontal in the closed end position of the door and parallel to the axis 6 then only horizontal drive forces can act through the connecting joint 9. Lifting of the door leaf by the closing force of the drive is thus prevented. Moreover, the frictional losses are minimal.
In the embodiment of the invention illustrated in Figs. 3 and 4 the support joint 4 is connected to a linear guide 21 so that in the support joint 4 only forces acting in a plane normal to the linear guide can be taken up.
For example this linear guide 21 is constructed as a square ball box. Thus in this embodiment also only forces in the direction of the axis of the piston and cylinder drive 10 are effective in the closed end position of the door.
