- Fig. 14 a cross section of a setting device with a drive device.
- FIGS. 1 and 2 each show a three-dimensional view of the drive device in an initial position (FIG. 1) or in a setting position (FIG. 2).
- the drive device has a one-piece or multi-part plunger 5, with one end of a not shown fastening means is directly or indirectly driven into a substrate, not shown.
- a rope rotation pendulum kinematics consisting of a tubular rotary body 4, the second winding cables 2, the spring elements 3 and the first winding cables 1 is used.
- the plunger 5 is linear, ie translationally displaceable, wherein it is guided along its longitudinal axis C, that is, in a longitudinal direction L, but can not be twisted.
- the plunger 5 of the tubular rotary body 4 is mounted concentrically rotatable, that is, the rotary body 4 can rotate relative to the plunger 5.
- the axis of rotation R is parallel to the longitudinal direction L.
- the rotary body 4 is hollow and the rod-shaped plunger 5 projects therethrough.
- the plunger 5 is thus arranged in the rotary body 4.
- the rotary body 4 is mounted axially (not shown) in such a way that rotation of the rotary body 4 is as friction-free and low-loss as possible, and the rotary body is arranged rigidly along the axis of rotation R.
- the first winding cables 1 connect the spring elements 3 to the rotary body 4, so that when rotating the rotary body 4, the spring elements 3 are tensioned, wherein the winding cables 1 at least partially wrap around the rotary body 4 or obliquely to the rotary body 4.
- the rotary body 4 is connected to the first winding cables 1 in such a way that a spring force acts on the rotary body 4 in both rotational directions of the rotary body 4.
- the second winding cables 2 connect the rotary body 4 with the plunger 5, wherein by rotation of the rotary body 4 in the direction of rotation B about the axis of rotation R, the second winding cables 2 loop around the plunger 5 and the resulting "apparent shortening of the rope" in a linear movement in the direction A. , so in the longitudinal direction L, put.
- the transmission ratio can be set, which converts the spring travel of the spring elements 3 in a path of the plunger 5.
- the drive device has the plunger 5, which expels a fastening means, not shown, through the setting opening 14.
- the linear, sudden movement of the plunger 5 is effected by the kinematics described in FIGS. 1 and 2, wherein a prestressed spring element 3 converts its energy via the first winding cables 1 into a rotational movement in the direction of rotation B of the tubular rotary body 4, which in turn converts its energy Rotary movement B on the second winding cables 2 in the linear movement in the direction A of the plunger 5 converts.
- a small spring travel can be converted abruptly into a large linear movement of the plunger 5.
- the rotary body 4 is rotatably mounted in the bearing elements 10, wherein it is not displaceable in the longitudinal direction. As a result, the rotary body 4 along the axis of rotation R is rigidly disposed relative to the housing 1 1
- the plunger 5 must be stored safely against rotation. Serves a rotationally and transversely rigid retaining membrane 6 at the opening 14 remote from the end of the plunger 5, alternatively also at the other end. This ensures that the plunger 5 converts the rotational movement of the rotary body 4 exclusively into a linear movement.
- the electric drive unit 7 For "loading” or “mounting” of the setting device, the electric drive unit 7 is used, which sets the rotary body 4 in rotation via a gear unit 8 and a coupling unit 9 and thereby biases the spring elements 3. With the coupling unit 9, the rotary body 4 can be kept in a tensioned position, which is released by the trigger button 13. Alternatively, the electric drive unit 7 can be switched off at maximum state of charge and thereby the setting process without intermediate holding the spring tension can be triggered. Due to the selected gear ratio and the kinematics of the second winding cables 2, the rotational body 4 only has to be able to rotate about +/- 45 degrees in order to set fastening means. Fig.
- FIG. 4 shows a cross section through a gas spring 15, which consists of two concentrically arranged Metallbälgen 16 which, closed by a common bottom plate 18 and a cover plate 17, form a hermetically sealed container for a gas.
- a gas spring 15 which consists of two concentrically arranged Metallbälgen 16 which, closed by a common bottom plate 18 and a cover plate 17, form a hermetically sealed container for a gas.
- the cover plate 17, not shown valve the container can be filled with gas.
- the effective radii of the two metal bellows 16 are dimensioned such that, for example, at a gas pressure of 50 bar, a force on the bottom or cover plate 17, 18 of about 20 kN results.
- First winding cables 1, which transmit the biasing force to the rope rotation pendulum kinematics, are hooked at one end to the cover plate 17 of the gas spring 15, with the other end on the rotary body 4.
- the first winding cables 1 are installed in the unpressurized state of the gas spring 15 so in that they are taut and slightly biased after being hung up.
- the first winding ropes 1 are radially aligned after hanging in the cover plate 17 of the gas spring 15 and in the rotary body 4 of the rope rotation pendulum kinematics in plan view of the cover plate 17, as shown in Fig. 5 can be seen.
- the rotary body 4 is prevented by a suitable bearing from moving in the direction of the longitudinal axis C. Rather, the rotary body 4 is only able to perform a rotation about the longitudinal axis C, which is concentric with the axis of rotation R. If the gas pressure spring 15 is filled with gas, a pressure builds up which acts on the cover plate 17 in the direction of the longitudinal axis C and thus exerts a pulling force on the first winding cables 1.
- the pressurized gas spring 15 generates a force on the first winding cables 1, the the suspension points of the first winding ropes 1 a Generate torque corresponding to the tangential component of the transmitted through the first winding cables 1 on the rotary body 4 force multiplied by the radius of the Einitatiticians on the rotary body 4.
- the plunger 5 located in the interior of the rotary body 4 can be displaced into a longitudinal movement according to FIGS. 1 and 2.
- An exemplary design provides at a pressure of 50 bar with a rotation of the rotating body 4 of 45 degrees about the longitudinal axis C, an initial torque of 300 Nm, which acts on the rotation body 4 on the rope rotation pendulum kinematics. Since the cable length does not change during dynamic operation, the lid plate 17 is pulled downwards in the direction of the bottom plate 18 by the rotation (FIG. 4) and thus the gas pressure spring 15 is compressed. This leads to a slight modulation of the gas pressure due to the pendulum movement of the rotating body 4. In the arrangement of FIG. 4 would act on a bearing for suppressing movement of the rotating body 4 in the axial direction, a resultant, significant force as soon as the gas spring 15 to its nominal pressure is pumped up. In the example, the nominal pressure is 50 bar, resulting in the given geometry of the gas spring 15, a force on the bearing (not shown) of about 20 kN results.
- FIG. 7 Such a bearing subjected to high forces can be completely avoided when a symmetrical arrangement is realized, as shown in Fig. 7.
- two gas springs 15 whose direction of force is opposite when pressurized, and two symmetrical arrangements of first winding cables 1, which are hereinafter referred to as "lower and upper winding cable arrangement".
- the forces exerted by the two gas springs 15 on the respective cover plates 17 on the first winding cables 1 on the rotary body 4 the opposite and therefore cancel each other.
- a bearing for the compensation of axial forces is therefore no longer necessary.
- the torques of the lower and upper winding cable assemblies act in the same direction, i. they add up.
- a compensation bore 19 may optionally be provided, through which a pressure equalization takes place.
- the balancing bore 19 may have a flow restrictor (not shown) for suppressing pressure oscillations between the two gas springs 15.
- first winding cables 1 as shown in Fig. 5 and Fig. 6, does not necessarily have to be four.
- the gas spring 15, which is constructed of metal bellows 16, has a serious advantage over other springs.
- vibrations of the metal bellows 16 have no appreciable influence on the volume V of the metal bellows 16 of the gas springs 15 and thus not on the pressure as the cause of the torque acting on the rotary body 4 via the first winding cables 1.
- interference due to unavoidable resonances are effectively decoupled.
- the triggering device 20 has a front crown wheel 21, which is rigidly connected to the rotation body 4 at an end surface and whose first teeth 22 are chamfered at least on one side, i. the tooth flanks are inclined with respect to the crown gear axis K.

- the first crown wheel 21 can alternatively also be arranged at a location of the lateral surface of the rotary body 4.
- the second teeth 24 can engage with the first teeth 22 in such a way that the first crown gear 21 is secured against rotation.
