Definitions
- the invention relates to a cast component made of a light metal material a casting insert used to increase damping.
- SiC, graphite, Al 2 O 3 particles and graphite, W, B, SiC, Al 2 O3 fibers are predominantly used as the reinforcement phase in the sense of an additional element that increases the damping.
- the composites are manufactured using the technologies of melt metallurgy, powder metallurgy and spray compacting. Another way to achieve a higher damping of the light metal materials is to manufacture porous materials.
- the porous structures can be adjusted using sintering technology and spray compacting.
- a porous material is also present in the metal foams produced by powder metallurgy and melt metallurgy.
- the design of the components with ribbing to minimize the Sound radiation is disadvantageous and manifold for reasons of weight and space not possible.
- the disadvantages of composite materials are in particular the higher ones Manufacturing costs by introducing the reinforcement phase or the additional Damping element in the matrix material and the problems with the complex Recycling of such materials.
- the porous materials the Compared to the solid material, the mechanical properties are significantly poorer a major disadvantage.
- US 5 523 171 A is a reinforced material for a connecting rod Motor vehicle became known. It is a cast aluminum connecting rod with a Casting insert made of stainless steel in the form of a fabric, disclosed.
- this fabric is disadvantageous in particular because of the wire used and in terms of mesh length and width labeled fabric formation not suitable, the internal damping of the To increase cast aluminum.
- the invention is based, for a cast component from a task Light metal material to increase the material or natural damping of the Light metal material to show an additional element in the form of a casting insert.
- the casting insert as a pressed molded part from one Wire texture is formed from a wire, from a highly damping nickel material with a purity of at least 99% and / or from one highly damping ferritic FeCrAl 20 5 steel, and each, from one Heavy metal wire and / or a wire made of a heavy metal alloy from Large material or natural damping formed part for complete Infiltration with the light metal material as a pickled before pouring Mesh with a mesh size of 2-30 mm and a mesh length of 1.5-15 mm that is formed in the connection areas of light metal matrix and respective heavy metal wires of the mesh with an energy input (Sound, structure-borne sound) caused by longitudinally elastic to the wires Deformations by means of dislocation movements and / or glide boundary sliding and / or interfacial friction an increased material or natural damping in Light metal material or in the cast component is achieved.
- Wire inlays in light metal components are e.g. from DE-B 1 134 481 for Purpose of component reinforcement known.
- the use of metallic is also for this Fibers known for example from DE-A 26 44 272.
- Mats made of metallic Threads in cast components are described in US Pat. No. 3,098,723 DE-Z "Archive for the ironworks, 43rd year, volume 7, July 1972, pages 571 - 575 "known to pour into aluminum or magnesium wires for Component reinforcement, an increased internal damping in the sense of the invention however, nowhere revealed.
- the advantage of the invention is a multiple increase over the solid material the internal damping of the light metal material used for a cast component to see.
- the cast component according to the invention in particular is used for die cast components, these in further Design as a vehicle and / or machine-bound die-cast components can be like e.g. an oil pan, a gearbox cover, one Cylinder head cover, gearbox housing, etc.
- the wire texture designed as a casting insert can be made of a fabric ordered structure and / or formed from a mat-like, disordered structure be such that a porosity for substantially complete infiltration is achieved through the light metal matrix.
- the wire texture is expediently made of multilayer wire knitted webs formed, which according to a particularly preferred embodiment of the invention from a round or flat wire with a diameter of 0.05-0.6 mm are formed.
- the process according to the invention takes the form of a die-cast part made of an aluminum alloy
- an element of such a heavy metal or Heavy metal alloy formed by great internal damping and when casting in essential completely infiltratable wire texture used as a casting insert that in the connection areas of the light metal matrix and heavy metal wires an energy input through sound or structure-borne sound through to the wires longitudinally elastic deformations an increase in material damping in the cast component is effected.
- the longitudinal elastic deformations caused by energy input are based in particular on dislocation movements, on interface friction as well as on grain boundary gliding.
- the knitted fabric from one Wire made of a highly damping nickel material with a purity of at least 99% formed is chosen in terms of its density such that a wire mesh porosity for substantially complete infiltration is specified by the aluminum alloy.
- a particularly high damping is achieved in that the wire texture as a pressed molded part of multilayer Wire mesh webs are formed with loops interlocking is, the wire knit molding is pickled for better pourability.
- a die-cast part with a casting insert made of a nickel wire knit results in opposite a die-cast part made of a solid aluminum alloy multiple Natural attenuation.
- a die-cast part with the inherent damping achieved according to the invention has an advantageous effect at frequencies such as those found in drive units of motor vehicles occur.
- a wire texture can also be used as a knitted fabric made of a wire made of a highly damping ferritic FeCrAl 20 5 steel are formed, preferably also as pressed and pickled Knitted wire molding.
- a wire texture serving as a casting insert can also be used be formed from wires from both materials.
- the wire texture designed as a casting insert can also be a fabric-like one ordered structure and / or from a mat-like, disordered structure be formed such that a porosity for substantially complete infiltration is achieved by the respective light metal matrix.
- the method according to the invention offers, in addition to the advantageously sound-absorbing Effect the further advantage that through the use of metallic wire mesh the highly damping light metal material easily and completely is recyclable.
