Definitions
- the invention relates to a vehicle door, in particular for a series motor vehicle, with a hinged on the vehicle structure via a door hinge hinged, weight-increasing door leaf, according to Preamble of claim 1.
- Manually hinged vehicle doors of this type especially those from standard motor vehicles, generally included as a swivel lock one between the hinge-side edge area of the door leaf and the front door spar arranged to limit the opening angle of the door Tether including a spring loaded door leaf in the open position holding latch. If the dead weight of the door leaf is e.g. are increased many times over by pre-built protective plates such safety devices and spring catches too weak, the impact force the door leaf, especially when opening the door on the inclined slope, intercept or hold the door leaf securely in the open position. The consequence are damage to the vehicle door and a risk of injury to the Vehicle occupants when getting on or off.
- the object of the invention is so a vehicle door of the type mentioned train that the door leaf even with high weight and strong Vehicle inclination at the end of the door opening path and in every intermediate position is securely intercepted and held stable in the open position.
- the various fuse-locking functions should be in one compact Unit be integrated.
- This object is inventively characterized by that in claim 1 Vehicle door released.
- a passively operated piston-cylinder unit with hydraulic reset lock provided that according to claim 2 in a structurally particularly simple manner consists of a check valve, which is the backflow of the hydraulic fluid from the hydraulic chamber that enlarges when the door swings open locks automatically and unlocked to close the door.
- a check valve which is the backflow of the hydraulic fluid from the hydraulic chamber that enlarges when the door swings open locks automatically and unlocked to close the door.
- Check valve according to claim 3 preferably unlocked by a door handle.
- the piston-cylinder unit according to claim 4 is preferably with end stop damping acting in the extension direction and / or formed according to claim 5 double-acting and in the connecting lines the hydraulic chambers each equipped with a throttle point, the Throttling points according to claim 6 expediently one to each connected in parallel, opening to the corresponding hydraulic chamber One-way valve is assigned to undesirable vacuum conditions in the To prevent hydraulic chambers when opening or closing the door.
- the vehicle door shown in the figures contains one on the front door spar Door hinges that can be pivoted open manually about the door hinge axis A.
- Door leaf 106 which is retrofitted on the outside of the door leaf attached front armor 108 is reinforced to increase weight.
- the weight of the front armor 108 is many times higher than the original one Dead weight of the door leaf 106, so that the usual tethers and spring catches of series vehicles are not sufficient, the armored Intercept door leaf 106, 108 when opening the door on the inclined slope or the Keep the door leaf securely in the open position.
- FIG. 1 and 2 show the hydraulic swivel lock 110 when closed (Fig. 1) and partially open vehicle door (Fig. 2).
- the swivel lock 110 contains a passively operated, double-acting hydraulic piston-cylinder unit 34, which with its Cylinder 36 via a pivot 114 on the door leaf and with its piston rod 38 over one further pivot 116 to a load-resistant force application point on the Vehicle structure is connected.
- the hydraulic chambers 40, 42 of the piston-cylinder unit 34 are by means of a two-part hydraulic pressure accumulator 44 permanently pressurized, such that those acting on opposite sides of the piston Remove pressure forces.
- the connecting line 46 at the Swinging open the door enlarging hydraulic chamber 40 are a to the hydraulic chamber 40 opening check valve 48, which via a control lever 50 together with the operation of the door handle is released, and a throttle point 52 and one parallel to this switched, further check valve 54, which is also the hydraulic chamber 40 opens.
- the fluid port 56 of the piston rod side hydraulic chamber 42 also contains a throttle point 58 and one parallel to it switched check valve 60 opening to the hydraulic chamber 42.
- the throttle 58 to one of the Cylinder end spaced control port 62 connected in the Final phase of the extension stroke of the piston-cylinder unit 34 from itself Run over increasingly narrowing control slot 64 of the actuating piston 66 and consequently is controlled more and more until the piston 66 the full extension position reached.
- the door is consequential the stop of the piston 66 on the cylinder front wall against another Opening movement positively secured and at the same time the Cylinder chamber 40 due to the blocking action of the check valve 48 hydraulically locked so that the door is rigid with the Vehicle structure is coupled.
- the door handle is actuated and thereby the check valve 48 opened via the control lever 50.
- Check valve 54 remains locked, so that the throttle point 52 from the out of the cylinder chamber 40 displaced hydraulic fluid flows through and thereby the closing speed the door is confined while the cylinder chamber 42 is open the way through the check valve 60 unhindered with hydraulic fluid is refilled from the memory 44.
