Definitions

  • the invention relates to a reciprocating internal combustion engine with an engine block consisting of cylinders, cylinder heads, crankshaft together with engine, camshaft with control wheels and intake and exhaust manifold, which has an at least partially enclosing, multi-part, a common oil chamber formwork, the structure-borne soundproofing sealing elements on Engine block is attached, wherein the engine block, the flywheel housing and possibly the gearbox are rigidly connected to one another.
  • the object of the invention is to eliminate these deficiencies and to provide a reciprocating piston internal combustion engine of the type described at the outset, which ensures the greatest possible sound insulation with reduced technical outlay.
  • the invention solves this problem in that the unit is suspended on the end facing away from the flywheel with the interposition of an elastic and structure-borne sound-absorbing element on a cross member and has lateral eyes in the rocker-wheel housing with elastic and sound-absorbing lining for trunnions, the formwork as a unit by means of a ring designed sealing elements in the area of the end faces of the engine block is supported on this.
  • the formwork forms a unit in itself, it only needs to be attached to the engine block as a whole to reduce structure-borne noise and oil-seal in order to achieve effective sound insulation even if the formwork itself consists of parts that are only oil-tight but not sound-proof connected, because of the formwork as a whole is no longer transmitted structure-borne noise. It is therefore sufficient to connect the individual parts of the formwork in a simple manner without special insulation measures, so that there is a corresponding reduction in the technical outlay and the costs.
  • the support of the unitary formwork on the front sides of the engine block offers the possibility of using the ring-shaped sealing elements, which ensure secure mounting without the use of the necessary sound-transmitting fastening screws or the like.
  • the auxiliary devices such as alternator, water pump, filter, oil cooler, compressor and / or. Like., attached. This avoids stressing the formwork by these auxiliary devices, and the wall thickness of the formwork can be kept very small. In addition, the vibrating mass of the formwork is of course also reduced, so that there are, if at all, only very small vibration amplitudes with respect to the engine block.
  • a bearing plate which is coaxial with the crankshaft and serves as a cover, is fastened to the crossmember with a bearing for the shaft of the drive of the auxiliary devices, and this shaft is connected to the crankshaft via an elastic coupling which isolates structure-borne noise. Since the drive shaft of the auxiliary devices is mounted in the bearing plate attached to the cross member, there are no relative movements between the auxiliary devices and the drive shaft. On the other hand, the radial relative movements between the crankshaft and the drive shaft for the auxiliary devices resulting from the elastic mounting of the unit formed in the cross member can take place unhindered and without harmful effects.
  • the end shield has the further advantage that it covers the crankshaft end together with the vibration damper that is usually present in a noise-absorbing manner.
  • the casing has an elongated opening in the area of the exhaust manifold, which is closed by a housing enclosing the exhaust manifold with the interposition of an elastic and structure-borne sound-absorbing seal, so that the exhaust manifold is also soundproofed.
  • the housing is attached to the cylinder heads with the interposition of a structure-borne sound-absorbing seal, and the edge of the formwork opening nestles against the housing with the interposition of an elastic seal, which in the edge region of the opening consists of layers separated from one another by heat-resistant and structure-borne sound-insulating flat seals.
  • an elastic seal which in the edge region of the opening consists of layers separated from one another by heat-resistant and structure-borne sound-insulating flat seals.
  • the flywheel housing can have its own formwork supported on it or on the trunnion under structure-borne sound insulation, optionally enclosing the starter, to which a gearbox formwork can then be connected.
  • the starter is attached to the flywheel housing in the usual way and thus does not perform any relative movements with respect to the flywheel.
  • the engine block is enclosed on all sides by a casing 9, the u a removable cover 10 to make the valve rocker arms accessible. Like. And has an oil pan 11 and forms an oil space.
  • the casing 9 is fastened to the engine block I via structure-borne noise-isolating sealing elements 12, 13, the sealing elements 12, 13 being arranged on the end faces of the engine block I and being designed in a ring shape.
  • a cross member 15 with the interposition of an elastic and structure-borne sound-absorbing ring 16, auxiliary devices such as alternator 18, water pump 19 and compressor being attached to the cross member 15, which in turn is supported on longitudinal members 17 of a chassis 20 (Fig. 3) are attached.
  • a bearing plate 21 which is coaxial with the crankshaft 3 and serves as cover, is screwed to the cross member 15 and is provided with a bearing 22 for the shaft 23 of the drive pulley 24 for the auxiliary devices 18, 19, 20.
  • the shaft 23 is connected to the crankshaft 3 via an elastic coupling 25 which isolates structure-borne noise.
  • the flywheel housing 8 has its own formwork 27 supported on it with the interposition of structure-borne sound-absorbing rings 26, which part 27a also encloses the starter. 2 eyes 28 are provided in the flywheel housing 8, which have a rubber lining 29 and are used to support trunnions 30 for the unit formed.
  • the cladding 27 of the flywheel housing 8 is supported on the trunnion 30 also by means of structure-borne rings 31.
  • the casing 9 has an elongated opening in the area of the exhaust manifold 7, which opening is closed by a housing 32 surrounding the exhaust manifold 7.
  • the edge 9a of the opening of the casing 9 nestles against the housing 32 with the interposition of an elastic seal 33 (see in particular FIG. 5), which in this edge region of the opening consists of layers 32a, 32b, 32c separated by heat-resistant and structure-borne sound insulation 34 consists.
