Definitions
- the present invention relates to a mechanical supercharger for internal combustion engines for conveying intake air according to the preamble of claim 1.
- superchargers can be compared to air pumps that deliver intake air under increased pressure and with higher density into the ner combustion chamber of an internal combustion engine and thereby improve its filling.
- exhaust gas turbochargers which use the otherwise lost flow energy of the exhaust gases
- mechanical superchargers which are driven by the crankshaft of the engine.
- a supercharger with a mechanical drive
- the engine crank mechanism of the engine is transferred directly to the supercharger via a corresponding clutch, so that in this, depending on the design, a compression wheel compresses a large amount of fresh gas during the intake stroke and supplies the cylinders.
- Such a supercharger is characterized by a rapid build-up of boost pressure and a high torque, even in the lower speed range.
- mechanical superchargers compensate for the disadvantage of exhaust gas turbochargers, especially in diesel engines, which consists in the fact that in the lower speed range, due to the inertia of the exhaust gases, the exhaust gas turbocharger can only react with a slight delay to rapid changes in the accelerator pedal position (turbo lag), which reduces performance diminished for a short time and the soot emission is increased due to non-optimal combustion. Since a mechanical supercharger does not intervene in the exhaust system of the engine, the mass moments of inertia of the exhaust gases that always occur when the load changes do not come into play.
- single-stage spur gears are preferably used in the prior art.
- the invention has for its object to provide a loader that takes up a small amount of space while maintaining high efficiency and high torques, is inexpensive to manufacture and is characterized by a long service life.
- the present invention proposes a mechanical loader with the features of claim 1.
- the principle essential to the invention is based on the fact that a so-called circular thrust gear is used as the high-ratio gear, as is known, for example, from DE 195 15 146 C2.
- the principle of a circular thrust transmission is based on the fact that a plane is set into a circular pushing movement by means of at least two so-called blind cranks and a drive crank each with the same radii, that is to say that every point of this plane travels in a circular motion without it being arranged in a rotationally fixed manner Axis rotates through this plane so that a circular thrust is carried out.
- the two blind cranks and the drive crank are usually located on the corner points of an acute-angled, possibly isosceles triangle.
- this plane thus formed is now formed by a gearwheel which meshes with another gearwheel. This can be, for example, a ring gear with internal teeth, in which a spur gear runs, and which is set in a circular thrust, or the spur gear itself.
- the surface speed of the driven gear tooth flank, whether spur or ring gear, in a uniform rotation depends on the output speed that is present as a result of the selected transmission ratio and the selected diameter of the driven spur or ring gear.
- the circular thrust gear of the mechanical loader has a ring gear with an internal toothing, a spur gear with an external toothing which is in engagement with the ring gear and at least two blind cranks and a drive crank, one of the gear wheels being a rotation-free circular one by the drive crank
- the other gear is rotatably mounted about a fixed axis.
- the rotatably mounted axle can be a drive-side or an output-side connection shaft in the loader.
- the ring gear is connected on the output side to the ner Actuallyrrad and the spur gear on the drive side to the clutch, the spur gear being set into a rotation-free sliding movement by the drive crank.
- the bearings used in the transmission can be designed as ceramic bearings.
- the teeth of the individual gears of the transmission can be formed from a material that does not require lubrication, for example from a plastic or a sintered metal.
- the transmission and the compressor unit are arranged in a single integral housing, the integral housing having functional elements integrated therein, such as bearing shells, support disks, sealing elements and the like, depending on the respective design.
- a planetary gear is arranged as a gear between the clutch and the ner seal unit, which is constructed so concentrically that it takes up a much more compact space.
- the clutch is designed as an electrically actuable magnetic clutch, which e.g. switches off at idle and switches on during acceleration or at full load.
- the transmission arranged between the nerd unit and the clutch additionally has a clutch device with a freewheel which replaces the magnetic clutch and which is open when the engine is at a standstill and via the accelerator pedal position and a corresponding electronic control program for the vehicle transmission can be closed and opened as required and under load.
- the mechanical loader is characterized by the fact that it is inexpensive to manufacture, that there is no need for oil lubrication and cooling of the mink teeth, that the installation itself occupies a small installation space and thus the installation space of the overall arrangement of the loader, and that the loader operates quieter than conventional loaders, while maintaining the necessary requirements for high efficiency and high torques, as well as a long service life and low maintenance.
- Figure 1 is a schematic representation of the mechanical loader according to the present invention.
- FIG. 2 shows a basic sectional illustration of the circular thrust transmission from the mechanical loader according to FIG. 1.
- FIG. 1 shows a schematic representation of a mechanical charger 1 according to the invention.
- a circular thrust gear 4 shown here schematically as a “black box”, is arranged within the charger 1 between a magnetic coupling 2 and a nerd unit 3 with a compressor wheel (not shown).
- the Ner Actuallyrtician 3 has a suction side 5 and a pressure side 6 for the intake air.
- the circular thrust gear 4 and the ner seal unit 3 are integrated in a single integral housing 7.
- FIG. 2 shows a basic structure of the circular thrust gear 4 again.
- the circular thrust gear 4 has a ring gear 8 with internal teeth, which is connected on the output side to the compressor wheel with a connecting shaft 9.
- a spur gear 10 runs in the ring gear 8 and is connected on the drive side to the magnetic coupling 2 with a connecting shaft 11.
- the spur gear is connected via at least two blind cranks 12 to a drive-side flange 13, which in turn is firmly connected to a drive-side flange 14, in which the connecting shaft 9 is mounted on the drive side.
- the blind cranks 12 are designed as ball-bearing extenders, as is a drive crank, not shown, which puts the spur gear 10 into a circular thrust. All ball bearings 15 in the circular thrust gear 4 are designed as ceramic bearings.
- a counterweight 16 is arranged on the spur gear 10 as a balance mass.
