Definitions

  • the invention relates to an arrangement with connection rotational drive, an auxiliary member on an internal combustion engine, as well as a housing of training for the rotation of at least one auxiliary body.
  • auxiliary bodies such as that the starter, the generator, the assistance pump of direction, the water pump of the cooling circuit and many other bodies, which are necessary for the operation of a combustion engine or which are intended for particular uses of the vehicle driven by the internal combustion engine, are mounted at different places on the combustion machine internal. Very often these auxiliary bodies are driven by a belt passing through a mounted pulley in rotation on the engine for this purpose. Such an arrangement is disadvantageous in two respects.
  • each auxiliary body requests its own fixing means on the engine
  • the use of a belt brings a elongation of the engine in the axial direction of the crankshaft the engine, as well as the presence of a rotating part and generally uncovered (a pulley) outside the engine block.
  • Such arrangements give the formed ensemble by the engine and its auxiliary organs a volume enough important, especially when taking into account the volume empty space required to ensure minimum distances of safety around the rotating parts or to allow maintenance work, for example replacement of the belt. And this is especially true, when it comes to rotating two or three auxiliary organs.
  • the object of the invention is to propose an arrangement an internal combustion engine and one or more auxiliary organs to reduce the most possible space for the engine and its auxiliary organs, and which, preferably, simplifies also the assembly of these auxiliary organs on the engine.
  • the object of the invention is achieved with a arrangement, with connection by rotational drive, of an auxiliary member on an internal combustion engine comprising a bearing housing and a crankshaft with counterweights housed in the bearing housing, according to which the auxiliary member is provided with a pinion drive in rotation and is connected in training to the engine by means of a cascade of gears comprising less an intermediate gear and a crown, the crown being set on one of the counterweights of the crankshaft.
  • the length of the engine, seen in the axial direction of the crankshaft engine is no longer extended by a volume required for the location of one or more several belts and corresponding pulleys necessary for the training of auxiliary organs.
  • using one of the counterweights crankshaft and in particular crimping on it a crown acting as a drive pinion avoids the presence of a room openly rotating for the rotational drive of the organs Auxiliary.
  • the provisions of the invention allow to mount one or more auxiliary organs on a box of training and to mount this housing drive on the internal combustion engine, which greatly simplifies the assembly of auxiliary bodies on the engine.
  • the present invention thus makes it possible to obtain a quite significant reduction as well on the plane material only in terms of volume and costs of manufacture, of an engine equipped with auxiliary organs.
  • Figure 1 recalls a usual arrangement of a internal combustion engine 10 equipped with an organ auxiliary 2, for example a generator.
  • the generator 2 is driven by means of a belt 19 passing through a pulley 20 mounted on one end of a crankshaft 11 ( Figure 3) of the motor 10.
  • the width of the pulley 20, including the dimensions of the axis of the pulley 20 and those of the means fixing the pulley 20 on its axis of rotation, give to the powertrain, that is, to the whole formed by the engine and the means drive of the auxiliary member, a length significant extra. In some cases, this extra length makes group integration power train in a given chassis or in a platform particularly difficult data, for example when the engine has six or eight cylinders and is intended to the motorization of a passenger car.
  • the arrangement according to the invention represented on the FIG. 2, makes it possible to obtain, with respect to the arrangement usual figure shown in Figure 1, gains in motor length of the order of 30 to 40 mm, or 50 mm.
  • the engine 10 comprises a housing lateral training 1 containing part of a cascade of gables.
  • the housing 1, which forms a support for the auxiliary member 2 is mounted laterally on a bearing housing 3, and that of way that the axis of rotation of the auxiliary member 2 is parallel to the axis of rotation of the crankshaft 11.
  • the housing 1 is mounted directly on the bearing housing 3, flange 22 secured to the housing 1 and bearing on a flange 16 shaped for this purpose in the housing 3.
  • the crankshaft 11 In the housing 3 is housed the crankshaft 11 with its counterweights 4. One of the counterweights 4 of the crankshaft 11 is set with a crown 6 giving this counterweight 4 the additional function of a gear wheel.
  • the box 1 is disposed on the housing 3 in such a way that pinion 21 ( Figure 5) of the body auxiliary 2 is at least approximately aligned with the crown 6.
  • the drive pinion 21, one or several intermediate gears 5 (FIG. 4) and the crown 6 together form a kinematic chain of transmission for driving the auxiliary member 2 by a counterweight 4 of the crankshaft 11 of the engine 10.
  • this chain of transmission for example the number of teeth of each these elements, are determined primarily according to nature or type of auxiliary body to be trained in rotation.
  • the total ratio between the number of turns of the crankshaft 11 and that of the pinion 21 must be quite high, for example, in the range of 20 to 25. total ratio between these two speeds of rotation is determined by the product of all singular relationships gables and the intervening crown.
  • the organ 2 When, on the other hand, the auxiliary member 2 is a generator, the organ 2 must be able to function correctly up to the maximum speed of the motor 10 and at the same time provide the necessary current from a comparatively low rotation speed of the 10.
  • the total transmission ratio of the cascade of gables will only be, for example, of the order of 3 to 6.
  • other reports of transmission can be calculated according to the speed of rotation or torque required, for example, when the auxiliary member 2 is a pump for the fluid of a steering assistance system.
  • the arrangement according to the invention can operate with only one intermediate gear 5.
  • the crown 6 engraine with this intermediate gear 5 which, him, engraine with the pinion 21 of the auxiliary organ 2.
  • the report of transmission required for a certain application can be obtained with a number of sprocket teeth intermediate 5 quite high. Due to the large number of teeth, the pinion 5 will have a large diameter, which may result in the flange 16, and more especially the passage in the flange 16 through which the intermediate gear 5 engages with the crown 6, must be big enough. This condition can be done quite easily when it comes to develop an entirely new 10 engine in which the dimensions of the bearing housing 3 will be determined according to the necessary dimensions of the flange 16.
  • an engine must be modified in such a way that the layout according to the invention can be realized, the modification must take into account the dimensions of the bearing housing 3, which generally leads to a flange 16 of dimensions, and in particular of opening, limited.
  • the modification must take into account the dimensions of the bearing housing 3, which generally leads to a flange 16 of dimensions, and in particular of opening, limited.
  • the number of gables intermediate 5 is greater than three.
  • the use of four or more intermediate gears will generally be limited to special applications.
  • the first auxiliary element is a reversible machine that can work as well as generator that as a starter
  • the second organ auxiliary is a pump for the assistance system of direction of the vehicle
  • a third organ is a pump for the air conditioning system of the vehicle.
  • a different arrangement will be chosen when it comes to releasing a drive shaft from the 1 drive case, drive shaft that will serve, for example on an agricultural tractor, for the training various interchangeable tools according to the work at perform with this tractor.
  • FIG. configuration according to which the cascade of pine nuts includes, apart from the crown 6, two pinions intermediate 51, 52 fixed inside the housing 1 using screw-axes 71, 72.
  • the housing 1 comprises a support 23 positioned transversely with respect to the flange 22 and shaped to extend into the interior of the casing bearing cap 3.
  • the support 23 has a housing 14 for the intermediate gear 51. It comprises also, in the side wall of the housing 1, a housing 15 for the intermediate gear 52.
  • the axle screws 71, 72 respectively pass through the intermediate gear 51 and the intermediate gear 52 to be introduced and housed in the corresponding housing 14 or 15.
  • FIG. 7 represents this type of assembly in one schematic cross-section for the case of a pinion single intermediary. 5.
  • the screw-axis 7 is immobilized in the wall side of the housing 1 by means of a nut 7A.
  • the head of the screw-axis 7 is provided with a hexagonal hollow 7B intended to receive, when mounting the pinion 5, a key to six C. pans
  • Figure 8 shows, finally, a bearing housing 3 with the necessary modification for the layout according to the invention.
  • a flange 16 on which the housing 1 is fixed by means of screws 19 through the passage holes 13 of the housing 1.
  • the flange 16 includes four tappings 17 to receive the screws 19.
  • the flange 16 includes an opening 18 whose shape and dimensions are chosen so as to allow a engrainement between the crown 6 and the pinion intermediary housed partially within the opening 18 of the flange 16.
