Definitions
- the invention relates to a spring carrier arm of a spring carrier of a motor vehicle axle, in particular a gantry axle, having a longitudinal section and a subsequent to the one end of the longitudinal section, a flange flange portion, wherein the longitudinal section at least one attachment point for attachment to a shock absorber and / or having a suspension.
- Spring carrier arms of spring carriers are used in motor vehicle axles for the purpose of connecting the motor vehicle axle to the motor vehicle.
- the spring carrier hereby has two spring carrier arms, via which a connection to the shock absorbers and air springs positioned there in front and behind the wheels of the motor vehicle axle is made in the vehicle longitudinal direction.
- the respective spring carrier may in this case be composed of individual spring carrier arms which engage an intermediate housing, for example a portal housing or an axle housing.
- the object of the invention is therefore to provide a spring support arm of the type mentioned, which has a low weight at high load capacity.
- At least the longitudinal portion of the Federyarms consists of a lower shell and an upper shell made of a metallic material or a plastic with or without fiber reinforcement, the shell edges along the neutral bending fiber of the Federyarms, lower shell and upper shell along the neutral bending fiber the Federyarms are cohesively and / or positively connected with each other.
- This design makes it possible to design the spring carrier arm regardless of casting conditions essentially only according to stability criteria, so that its weight is significantly reduced.
- the cost of producing the Federbyarms is much lower than in the prior art, so that also reduces the manufacturing cost and labor and equipment costs.
- the flange section has a connecting piece which is welded to the longitudinal section at a distance from the flange of the flange section, the connection piece and the longitudinal section having identical cross sections in their welding region, then the welding point is far from the stress-critical region of the transition from the connecting piece to the flange and is not exposed to the high load occurring at this transition area.
- the end portion of the longitudinal portion opposite the flange portion may form a transverse portion extending angled to the portion of the longitudinal portion extending from the flange portion.
- the bottom of the lower shell can also from the flange
- Flange portion have a downward slope towards the end. If the lower shell has a continuous downwardly directed opening at its end region remote from the flange section, a natural outflow of water from the interior of the spring carrier arm is thereby made possible. At the same time, this results in a reduction in the weight of the Federlyarms.
- the mounting locations for attachment of a shock absorber and / or suspension may be spring pads inserted into corresponding openings on the top of the upper shell.
- one or both spring supports are press-fitted into the openings of the upper shell.
- one or both spring supports can also be connected in a material-locking and / or form-fitting manner to the upper shell.
- the suspension in particular an air suspension
- On the stability of the Federlyarms impairing through hole in the lower shell for screwing the air spring can be omitted if the attachment point for attachment of a shock absorber and / or suspension has a formed on the upper side of the upper shell or on the spring support threaded hole.
- the upper shell and / or the lower shell are steel forming parts, they have a high strength with the lowest possible weight.
- the Umformradien can be made variable so that the voltage is optimally distributed under load.
- the flange section and / or the longitudinal section consists of a fine-grained steel, a high strength is achieved while the parts still have good weldability.
- Figure 1 is a perspective view of a Federlyarms
- FIG. 2 shows a front view of the spring carrier arm according to FIG. 1
- FIG. 3 shows a rear view of the spring carrier arm according to FIG. 1
- FIG. 4 shows a sectional illustration of a transverse section of the spring carrier arm according to FIG. 1.
- the illustrated spring carrier arm of a spring carrier of a motor vehicle axle consists of a longitudinal section 1 and a flange section 2, wherein the longitudinal section is composed of an upper shell 3 and a lower shell 4.
- Upper shell 3 and lower shell 4 are formed as formed parts of metallic material or a plastic with or without fiber reinforcement and have U-like cross-sections, which have at the end to which the flange portion 2, about their largest cross-section. At the end opposite the flange portion 2, the cross sections of the upper shell 3 and the lower shell 4 decrease.
- the upper shell 3 and lower shell 4 are welded to one another at the free shell edges 6, 7 of the "U's.” This weld extends along the neutral bending fiber 5 of the spring carrier arm, but the upper shell and the lower shell can also be glued or materially bonded in a manner known to the person skilled in the art and / or be positively connected with each other.
- the flange section 2 produced as a forged part consists of a flange 8 and a connecting piece 9.
- the free end of the connecting piece 9 is welded to the same cross-section end of large cross section of the Federliniarms along an interface 10. However, these can also be glued or connected to one another in a manner known to the person skilled in the art in a material-locking and / or form-fitting manner.
- the flange portion 2 opposite end portion of the longitudinal portion 1 forms a to the extending from the flange portion 2 of extending portion of the longitudinal portion 1 extending transverse portion 1 first
- the upper shell 3 each have a circular opening 12 and 13.
- spring supports 14 and 15 are also used circular cross section with interference fit.
- the spring supports 14 and 15 are stepped and used with their small step in the opening 12 and 13 respectively.
- the provided for supporting an air spring spring support 14 has a centric threaded bore 1 6, to which the air spring is fastened via a threaded bolt.
- the spring support 15 is provided for supporting a shock absorber.
- the lower shell 4 has at its end portion remote from the flange portion 2 a recess 17 formed as a recess facing downwards.
- the rectangular flange 8 Due to the inclination of the lower shell 4, liquid penetrated into the interior of the spring carrier arm, such as water sprayed from the street, can flow towards the opening 17 and run outward through it.
- the rectangular flange 8 has at its corner through holes 18 for a screw fastening.
- the screw supports 19 surrounding the through-holes 18 can be produced with such a quality that no further processing is required.
