Preferred developments and embodiments of the invention will become apparent for all subject matter of the dependent claims, the following description and the figures.
- connection arrangement is characterized in that the transverse leaf spring has a ribbing on the at least one respective bearing point and the bearing device is formed with a notch or with notches into which the ribbing engages in a form-fitting manner.
- a ribbing comprises a plurality of ribs or webs projecting from the surface of the transverse leaf spring and arranged in particular parallel to one another.
- notches are internally formed on the bearing device recesses or grooves, which are formed and arranged so that a positive engagement of the ribs (similar to a tongue and groove connection) is made possible. That is, the ribs or ribs on the transverse leaf spring and the notches on the bearing device are designed to correspond.
- the ribbing and the notches are formed so that a comb-like engagement is made possible.
- the connection arrangement according to the invention can also be referred to as a fastening system.
- the lateral forces transmitting positive engagement between the transverse leaf spring and the bearing device which is represented in the prior art by a complex thickening of the leaf spring geometry at the bearing point, according to the invention replaced by a ribbing, which engages in the notches on the bearing device (tongue and groove principle)
- the ribbing (or its ribs) and the notches are formed transversely to the longitudinal direction (spring longitudinal direction) of the transverse leaf spring.
- the ribs or webs of the ribbing break off and the transverse leaf spring slips longitudinally through the bearing device.
- the ribbing (or its ribs) thus forms a predetermined breaking point, which ensures a controlled failure.
- the ribbing is much easier to produce, in particular in comparison to the previous thickening, as explained below.
- the transverse leaf spring is integrally formed with the ribbing, wherein the ribbing in particular only from the plastic matrix material (of the fiber composite material or fiber-reinforced plastic), so that the ribs or webs are thus free of reinforcing fibers.
- a thermosetting resin is thus a purely thermosetting ribbing.
- the ribs or webs are only locally on the surface of the transverse leaf spring. In the manufacture of the transverse leaf spring they can be molded directly in the tool (eg. An RTM tool) without any additional effort, without causing it to a
- the ribbing can be formed only part of the area, for example. Only at the top and / or bottom of the transverse leaf spring. Preferably, however, it is provided that the ribbing is formed at the bearing point over the entire circumference of the transverse leaf spring.
- the notches on the bearing device are each designed accordingly, so that the positive, in particular comb-like engagement is made possible.
- the preferably formed from a metal bearing device may be formed so that the transverse leaf spring is stored directly therein.
- an indirect Be provided storage including the bearing device, for example.
- This bearing sleeve is, for example, an easily manufactured plastic injection-molded part, light-metal die-cast part or the like.
- the claimed with the first independent claim transverse leaf spring is designed as a beam-like spring element and made of a fiber-reinforced plastic.
- this transverse leaf spring is characterized in that the central bearing points (in the central region of the transverse leaf spring) are formed with ribs for the positive engagement in suitably designed bearing devices (central bearings).
- the transverse leaf spring preferably has two such central bearing points.
- the claimed with the second independent claim storage device for attaching a transverse leaf spring which is in particular a central warehouse device, has two interconnected half shells, which engage around the transverse leaf spring at the bearing point form fit.
- the half shells are formed, for example, of metal.
- at least one of the half-shells is formed on its (the transverse leaf spring facing) inner wall with notches into which the ribs formed on the transverse leaf spring can engage.
- Fig. 1 shows in a perspective view of a transverse leaf spring for a motor vehicle.
- FIG. 2 shows a schematic sectional view of a connection arrangement for the attachment of the transverse leaf spring of FIG. 1 on a motor vehicle.
- FIG. 3 illustrates the controlled failure of the connector assembly of FIG. 2.
- FIG. 4 shows, analogously to the representation in FIG. 2, a further possible embodiment of a connection arrangement.
- Fig. 1 In the transverse leaf spring 100 shown in Fig. 1 is a
- the transverse leaf spring 100 is mounted transversely to the direction of travel. The ends are connected by means of guide bearing 110 with the wheel carriers. In the middle region, the transverse leaf spring 100 is connected by means of central warehouse 120 with the vehicle body. The two central warehouse or central storage devices 120 are arranged symmetrically to the center of the transverse leaf spring 100.

- the central warehouse 120 forming bearing device has two interconnected half shells 121 and 122, which together form a holding device and the transverse leaf spring 100 at embrace the bearing with a positive fit.
- the transverse leaf spring 100 reinforced with a plurality of fiber layers is formed with a ribbing 105 at the bearing point.
- the individual ribs or webs of the ribbing 105 are free of reinforcing fibers and consist only of plastic matrix material, in particular a cured one
- thermosetting resin pure resin
- the bearing device 120 or its half shells 121 and 122 are formed with corresponding notches 125 into which the ribbing 105 engages in a comb, so that an undercut positive connection between the transverse leaf spring 100 and the bearing device 120 results at the bearing point. This can be done on the
- the transverse leaf spring 100 can thus take, for example, also Rad Replacementsauf the.
- the ribbing 105 on the transverse leaf spring 100 is formed (for example, by dimensioning the rib width and by the number, distribution and arrangement of the ribs) that their ribs when exceeding a defined lateral force F (eg. In a heavy curb impact) break or tear off and the transverse leaf spring 100 slips through the bearing device 120, as illustrated in Fig. 2 by means of arrow.
- the ribbing 105 thus has an integrated breakage function to ensure a controlled failure.
- ribbing 105 can be determined, for example, by calculation, simulation and / or experiment, taking into account the maximum transferable lateral force F.
