Definitions
- the invention relates to a vehicle door, in particular a tailgate of a vehicle, in particular a military vehicle.
- tailgates From the civil and military vehicle industry doors and tailgates are known as access to an interior. In armored vehicles, tailgates similar to a door generally allow access to a protected interior of a military vehicle, the so-called combat space. The tailgates serve on the one hand for a quick rise and fall of a crew, on the other hand for a fast loading and unloading of equipment, ammunition, wounded etc. The following is representative of a vehicle door from a tailgate. However, the description applies unrestricted to other vehicle doors.
- the tailgate should be designed to withstand a threat.
- the tailgate is designed accordingly on the material side.
- Mainly such tailgates are made of armored steel. Associated with this is a high dead weight of the tailgate.
- the high weight of the chopping flap requires appropriate interpretations of the hinges and the opening mechanisms. Often tailgates are therefore hydraulically or motor assisted in the opening and closing process.
- a device for protecting the crew of a military vehicle has a flap on the stern for the entry and exit of the crew.
- the flap is pivotally mounted at the rear of the vehicle about a horizontal axis lying on the vehicle floor.
- the tailgate is used in the shut down state as entry and exit and is formed on the inside as a step and slope for the height overcoming of the overgrown soil to the vehicle floor.
- a storage space forms between the plate and the tailgate.
- the plate itself can spring-assisted manually or power assisted swivel.
- the opening angle of the flap is approached by means of position sensors and the flap is locked in the corresponding positions.
- a vehicle door in the form of a tailgate is described in EP 2 375 214 Bi.
- the tailgate and a ballistic protective element are connected to each other so constructively that both can be pivoted together on the vehicle about a common axis.
- the tailgate can be transferred from a closed position to an open position.
- the ballistic protective element occupies a distance above the ground in the open position of the tailgate, the tailgate forming a step relative to the ballistic protective element.
- a direct entry and exit on the thus resulting level by the height difference between the upper edge of the tailgate and the ground level is not given here.
- the high level or several levels not only represent a great ergonomic burden for the crew when setting up and setting down during the day and at night, but also pose a high risk of injury to the crew.
- the invention has as its object to avoid the aforementioned disadvantages, but at least to minimize.
- the invention is based on the idea to show an ergonomic tailgate.
- a reduction of the level is sought in the vehicle. That is, the tailgate or tailgate system as access to the vehicle is ergonomically shaped so that the first tread height between the tailgate and floor can be made very small.
- the tailgate comprises at least one plane, preferably slightly curved first, upper plate and a, preferably plane second, lower plate.
- the upper plate is the plate, which is arranged in a horizontal positioning of the tailgate on the lower plate. Both plates are spaced apart and mechanically interconnected. As connecting elements struts or struts or the like are preferred.
- the selected structure of the tailgate and the formation of a cavity, the weight of the tailgate can be minimized. Although such an approach is provided by DE 100 03 823 C2, this is implemented differently. The weight minimization allows a simple To use articulation and a simple swivel device. Further weight optimization is feasible through the use of new materials.
- the tailgate can be pivoted from a closed position to an open position and vice versa about a horizontal axis lying on the vehicle floor. This axis is assigned to the tailgate and the vehicle opening. When the tailgate is mounted, the tailgate axle is then aligned with the axle of the vehicle opening. The two plates are pivoted together about this common axis.
- the pivot axis is preferably below a vehicle opening.
- the surface of the first plate should preferably be flush with the inner surface of the combat space.
- the second plate of the tailgate can protrude beyond the rear of the vehicle in the closed position. This construction is particularly suitable when the rear of the vehicle on both sides of the vehicle opening on the rear vehicle wall extends backwards.
- the tightness of the vehicle in the area of the tailgate is realized via the first, upper plate of the tailgate, which engages a frame framing the vehicle opening.
- this frame is preferably made of a rubber.
- the upper plate surface of the tailgate preferably closes flush with the surface of the vehicle access or the lower surface or edge of the vehicle opening, so that no step is formed here.
- the distance of the upper plate to the lower plate is freely selectable depending on the protection requirement and / or ergonomic requirement.
- the greatest distance from one another is provided by the two plates in the area of the vehicle access or the vehicle opening.
- the curvature of the upper plate is in turn designed such that the distance between the two plates, seen in the open position, decreases away from the vehicle opening.
- the spacing of the two plates can thus be brought to a minimum step height by the shaping of the curvature.
- the approach to the tailgate is thus user-friendly.
- the new tailgate dispenses with edges, heels, screw connections etc. on the first panel.
- the missing edges, heels, screw connections, etc. enable a barrier-free loading area and minimize the risk of injury caused, for example, by tripping and / or falls.
- This construction also allows the integration of a rail system for the integration of a loading system for pallets, etc. Between the two plates creates a freely usable storage space This can be used to hold ammunition. Thus, under protection from the combat area reloading a weapon station or a tower system can be done. Additionally or alternatively, the storage space can also serve to accommodate equipment. Protected accommodation of water in this cavity is also possible.
- the storage space itself affects the interior of the vehicle as good as not, since this is due to the at least partially outside the actual combat space.
- the removal of this can be integrated into the tailgate objects can be done via a laterally arranged in the rear of the tailgate or the like.
- the pivoting of the tailgate is supported by at least one cylinder. This attacks, for example, with its piston to the rotational or pivot axis of the tailgate.
- the piston housing is then preferably fastened to the vehicle chassis. Also preferred are at least two cylinders, on both sides of the tailgate.
- Hydraulic cylinders pneumatic cylinders or motor-assisted systems can be used as cylinders.
- electric cylinders are used. Electric cylinders are self-locking linear drives, which means that no energy has to be supplied at standstill Electric cylinders convince with high-performance DC motors, signal cables, potentiometers and position detection sensors as well as integrated limit switches. It can be used on conventional electric cylinders, such as on Kurzhubzylinder up to heavy duty linear cylinder.
- a vehicle door In order to realize an improved access to a vehicle opening of the vehicle, a vehicle door is proposed, with a first plate and a second plate, which are spaced from each other.
- the first plate forming the access has a curvature, omitting edges, shoulders, screw joints, etc., which could form obstacles to accessing the vehicle. This curvature is preferably convex, ie pointing away from the lower plate executed.
- the plates are preferably spaced apart by struts, to reduce the dead weight of the vehicle door. Between the plates, there is a free space that can be used for various objects.
- Fig. 2 is a schematic representation of the tailgate of Fig. 1 in section.
- the vehicle 100 may be a military armored vehicle.
- the vehicle 100 may be a wheeled and / or tracked vehicle. Shown is a tracked vehicle with an illustrated right track drive 3, but also includes a left track drive.
- the vehicle opening 1 is located between two vehicle walls 101, 102 projecting laterally beyond this vehicle opening 1 on the rear of the vehicle 103, preferably centrally. At these vehicle walls 101, 102, the two crawler tracks are attached. The vehicle opening 1 can thereby extend the entire available space between the vehicle walls 101, 102. An eccentric arrangement of the vehicle opening 1 is also possible.
- the vehicle opening 1 is framed by a sealing ring, usually a rubber seal.
- At least one upper guide 5 is located in preferably close proximity to the upper end 4 of the vehicle opening 1, at least one upper guide 5. This is at the rear of the vehicle 103, for example, welded.
- Another lower guide 6 is mounted in the lower region on the vehicle rear 103 next to the vehicle opening 1.
- the guides 5, 6 each have a groove 5.1, 6.1.
- An electric cylinder The use of a hydraulic or pneumatic cylinder is also possible.
- the housing 22 of the cylinder 20 is secured to the vehicle rear 103, preferably screwed.
- the cylinder piston 21 engages laterally on the tailgate 2.
- the tailgate 2 comprises at least a first, upper plate 9 and a second, lower plate 11.
- the first, upper plate 9 is slightly curved and has a slight, upstanding curvature 12.
- the plates 9, 11 are structurally connected to each other via struts 13.
- the struts 13 can be covered by lateral plates (not shown in detail). These would slightly increase the weight of the tailgate 2.
- the distance between the two plates 9, 11 is individually selectable for each tailgate 2, depending on the ergonomic requirements. As a rule, a standard should be created.
- a space 14 resulting between the plates 9, 11 can be used for stowing various items of equipment, ammunition or other equipment to be carried.
- an access 15 is to be provided laterally to the tailgate 2 in its closed position.
- the tailgate 2 can be brought from a closed position (not shown in detail) into an open position. In particular, it can be pivoted about an axis A on the vehicle 100.
- the pivoting is caused by the at least one cylinder 20 and supported by this.
- the tailgate 2 pivots about the axis A upwards.
- the lateral pins 16, 17 engage the tailgate 2 in the groove 5.1, 6.1 of the respective guide 5, 6 a.
- the pivoting of the tailgate 2 from the closed position to the open position then runs in opposite directions.
- the tailgate 2 is led out of the closed position by the cylinder 20.
- the pins 16, 17 of the tailgate 2 leave the respective groove 5.1, 6.1 of the guides 5, 6. Die Tailgate 2 is then as long pivoted about the axis A until the tailgate 2 has taken its open position.
- the distance of the plates 9, 11 of the tailgate 2 can be taken into account with the distance of the plates 9, 11 of the tailgate 2 to each other an ergonomic requirement. But also the degree or the length of the curvature 12 of the first upper plate 9 can influence the ergonomics of the tailgate 2 take. With a larger curvature, the distance of the plates 9, 11 from one another in the region of the approach to the tailgate 2 can be reduced.
