  • the invention relates to a sound-proofing component for the sheathing of machines, particularly of internal combustion engines.
  • the cylinder block is formed by a framework made of steel plates and covered on both sides and in the area of thecrankcase by sound-proofing multilayer plates called sandwich metal sheets.
  • these sound-proofing elements consist of two massive steel plates arranged in spaced relation to each other, and interconnected by means of an interposed layer of sound-proofing material in such a manner that the inside steel plate only is screwed onto the crankshaft housing with the interposition of packing strips-However, this type of sound-proofing is highly objectionable insofar as it strongly impairs the abduction of heat from the cylinder block towards its surroundings, inasmuch as in view of its low thermal conductively the sound-absorbing material also acts in a heat-insulating capacity. This leads to an objectionable rise of the oil temperature which will have to be compensated by appropriate measures such as for example, the provision of a large-sized oil cooler.
  • such a component is characterized by a first frame member rigidly attached to the outside of the machine and by a second frame member arranged in spaced relation to and in front of, the first and connected with the same by means of a sound-proofing packing along a continuous series of lines, the said second frame member covering at least part of the outer surface of the machine and/or serving as a support for one or several encasements.
  • the framework construction of the component according to the invention offers not only the advantage of its low weight, but in addition the possibility of providing a component of appropriate rigidity to be used also as a supporting element.
  • the external second frame member is so designed as to serve as a support for encasements, it will be possible for such elements as are directly associated with the machine, such as the oil sump of an internal combustion engine for example, to be attached to the said second frame member as encasements. This further simplifies the overall design of the machine and additionally-helps reduce its weight.
  • one of the two frame members is designed as a closed, possibly arched plate and/or reinforced by means of corrugations.
  • This design is particularly suitable for the sound-proofing encasement of large surfaces of the machine.
  • At least one of the two frame members can be designed at least one of the two frame members can be designed as a strip having a mounting rim protruding from the packing either on one side or both.
  • the encasements provided can be attached to the mounting rim in any convenient manner such as by screwing, gluing or rivetting. lf desirable in view of the particular shape of the encasements to be mounted, it is also possible for the mounting rim of the strip-shaped frame member to be of angular-shaped or of any'other convenient form.
  • the strip-shaped frame member can be attached alongside its mounting rim to the rim of a connecting plate provided on the outer surface of the machine by welding, gluing, flanging or the like.
  • the additional connecting plate provides positive sealing of the encased machine compartment against the outside.
  • the encasements mounted on the second sound-proofing frame member or the external frame member designed as a plate are exclusively used for sound-proofing purposes.
  • the distance between the additional connecting plate and the sound-proofing plate in front of it is of particular importance for the sound-proofing capacity of the component according to the invention. The most convenient distance should be determined by trial and error.
  • the packing made of rubber, synthetic material or the like is attached to the two frame members by vulcanization or gluing.
  • attachment by vulcanization is feasible only in connection with a component according to the invention, since at least one of its frame members is open-worked so that the packing can be easily heated to the required uniform vulcanization temperature.
  • an additional support for the second frame member or for an encasement attached thereto by means of at least one sound-proofing supporting element mounted on the outer surface of the machine or on the first frame member. This helps eliminate objectionable vibrations particularly where large-sized encasements are used.
  • the provision of additional supporting elements may, however, prove useful also for considerations of a mechanical nature.
  • FIG. 1 shows a diagrammatic cross-sectional viewof the cylinder block of an internal combustion engine encased by means of sound-proofing components according to the invention
  • FIG. 2 illustrates a detail of FIG. 1 on a larger scale
  • FIGS. 3 to 5 are cross-sectional view of various types of sound-proofing components according to the invention.
  • FIG. 6 is a diagrammatic cross-sectional view of yet another embodiment of the invention.
  • FIG. 7 is a cross-sectional view on line VII-VII of FIG. 6.
  • the housing 1 of an internal combustion engine is provided with a sound-proofing sheathing substantially comprising two sound-proofing components 4 and 5 spaced in front of the two side walls 2 and 3 of the housing 1, and a further soundproofing component 6 arranged on the lower rim of the housing 1 and to which the oil sump 7 is attached.
  • the essentially identical components 4 and 5 comprise a first frame'member l rigidly mounted on the housing 1 by means of bolts 8 with the interposition of a continuous profile washer 9 and connected to a plateshaped second frame member 11 by means of a continuous elastic packing 12 in such a manner as to provide effective sound isolation.
  • the packing 12 made of rubber for example, extends alongside the first-mentioned frame member 10 and is positively and tightly attached thereto and also to the plate-shaped frame member 1 by vulcanization or gluing.
  • the plate-shaped frame member 11 is reinforced by means of horizontal and vertical corrugations 13 and 14.
  • the frame member and the packing 12 are somewhat enlarged for receiving the bolts 8.
  • the bolts 8 are countersunk in a stepped through bore 15 and rest with the interposition of a circlip 16 upon the annular shoulder formed by the bore 15 on the inner frame member 10.
  • the component 6 mounted on the underside of the housing I also comprises two frame members 10' and 11' interconnected by means of a sound-proofing elastic packing 12' and screwed to the lower rim of the housing 1 with the interposition of a continuous profile washer 9'.
  • the strip forming the outer frame member 11 presents a mounting rim protruding inwardly from the packing 12', the upper rim 17 of the oil sump 7 being attached to the said mounting rim by means of an oiltight flange 18.
  • the coil sump 7 forms a soundproofing encasement attached to the housing 1 and serving to screen off sound radiation from the housing I downwards.
  • the oiltight and substantially bend-resisting design of the sound-proofing components 4 and 5 makes is possible for the sidewalls 2 and 3 of the housing 1 to be provided with large-area recesses in such a manner that the components 4 and 5 themselves form the oil-wetted outer walls of the housing 1. This eliminates the need for providing double-walled outer surfaces of the housing and helps save much weight.
  • the front walls of the housing I could be sheathed by means of sound-proofing components of a similar design in such a manner as to inhibit heat radiation from the machine on all sides.
  • FIG. 3 shows a particularly plain type of component designed according to the invention.
  • the inner frame member 20 directly adjoining the body 19 of the machine to be sound-proofed is designed as through plate and the second frame member 21 connected therewith by means of a sound-proofing elastic packing 22 as a strip with an inwardly protruding mounting rim.
  • a plate-shaped encasement 23 is positively connected with the frame member 21 in any convenient manner such as by gluing the members 21 and 23 (right side of FIG. 3) or by means of rivets 24- (left side of FIG. 3).
  • the two frame members 20 and 21 of the sound-proofing component are designed as strips having a laterally protruding mounting rim, a separate connecting plate 25 directly adjoining the machine body 19 presenting a laterally protruding rim to which the inner frame member 20' of the sound-proofing component is attached.
  • the members 20 and 25 can be interconnected by any convenient method, such as for example by welding (right side of FIG. 4) or by fianging (left side of FIG. 4).
  • An encasement 26 forming a salient bonnet is attached to the mounting rim of the outer frame member 21 by means of rivets 27 (right side of FIG. 4) or self-tapping screws 28 (left side of FIG. 4).
  • the component shown in FIG. 5 comprises a stripshaped inner frame member 20" and a plateshaped outer frame member 21' connected therewith by means of a sound-proofing elastic packing 22.
  • This design also uses a separate connecting plate 25' directly adjoining the machine body 19.
  • the plate 25' can either by mounted on the machine body 19 jointly with the frame member 20" by means of bolts 8 (right side of FIG. 5) or else the members 25' and 20" are interconnected by flanging at the rim (left side of FIG. 5).
  • FIG. 6 illustrates the sound-proofing connection of an oil sump 29 to the lower rim of the housing 1' of an internal combustion engine (not shown).
  • the oil sump is mounted thereon by means of a sound-proofing com ponent 6' comprising a first frame member 30 designed as a sectional strip and a second strip-shaped frame member 32, interconnected by means of a soundproofing elastic packing 32.
  • the component 6' is mounted on the housing 1 by means of bolts 8 with the interposition of a profile washer 33.
  • the frame member 31 has an inwardly protruding mounting rim to which the inwardly bent upper rim 42 of the oil sump 29 is attached by welding.
