Definitions

  • the present invention relates to a pressure wave charger according to the preamble of patent claim 1.
  • Such a pressure wave supercharger which is mainly used as a charging device for an internal combustion engine, has a rotor provided with cells on the circumference, the rotor shaft of which carries at one end a pulley which is intended to be driven by a belt by the internal combustion engine to be charged, and also a rotor which encloses the rotor Rotor housing as well as a gas housing or on its two end faces.
  • an air housing each with channels for the supply and discharge of the gaseous exhaust gas or air, whereby the bearing elements for the shaft of the rotor are accommodated in the air housing.
  • the rotor of a known pressure wave supercharger of this type is driven by the internal combustion engine to be charged via the belt mentioned and the pulley, which is rigidly connected to the rotor shaft, with a constant transmission ratio.
  • the rotor speed is therefore proportional to the speed of the motor, which is why we speak of a "proportional drive" in this context. Since it is with Interaction of a charger with a motor depends on the fact that it works with the best possible efficiency in the speed range predominantly used for practical operation, the geometric data of the control elements of the pressure wave charger, which are mainly decisive for the charger efficiency, i.e. essentially the opening and closing edges of the Air and gas ducts as well as the auxiliary ducts, including the gas and compression pockets, are designed for this speed range, which corresponds to approximately 50% of the nominal speed.
  • this pressure wave supercharger which is designed for a preferred engine speed range that is operationally and economically most important, has the disadvantage that the pressure wave process does not run optimally in the lower and higher speed range of the engine.
  • the best possible exchange of energy between the exhaust gas and the charge air requires a different geometric design of the air, gas and auxiliary ducts, in particular their opening and closing edges.
  • the applicant's CH application 826 / 86-9 describes a free-running pressure wave charger driven by the gas forces.
  • the rotor speed does not depend on the motor speed, but on the resulting swirl energy of all air and gas flows acting on the rotor.
  • a narrower speed range of the pressure wave supercharger should be obtained than with the proportional drive.
  • the measures proposed there are intended to increase the drive impulse of the exhaust gases for turning up the rotor after the engine has started, to control the speed characteristic of the rotor and to counter overspeed.
  • the present invention arose from the task of avoiding the above-described disadvantages of the pressure wave charger with proportional drive and the pressure wave charger with free wheel rotor driven solely by the gas forces in a pressure wave charger, and by combining their advantages a better adaptation of the delivery characteristics of the charger to the load condition of the engine to obtain.
  • the pressure wave supercharger according to the invention is characterized in that there is a one-way clutch between the pulley and the rotor shaft and a roller bearing is provided on both sides thereof.
  • the pulley When the pulley is mounted on the rotor shaft in this way, it is carried along by the pulley via the clamping one-way clutch at a speed proportional to the motor speed as long as the torque exerted by the swirl energy on the rotor cells is smaller than that for the respective operating state including the share required for the transient state.
  • the frictional connection between the sprags and the outer ring of the one-way clutch, which is stuck in the pulley is released and the rotor runs at a higher speed until the engine revs up due to increased fuel supply and the Has caught up the pulley over the rotor and this is driven proportionally again.
  • This engagement and disengagement can basically take place over the entire speed range.
  • the rotor speed is set to a value dependent on the drive energy of the exhaust gases, but the rotor speed will never drop below the value given by the gear ratio between the drive pulley of the motor and the pulley on the rotor shaft.
  • 1 denotes a rotor housing, which encloses a rotor 2 and is sealed on its end faces by an air housing 3 or a gas housing 4.
  • the arrow 5 indicates the entry of the intake air into a low-pressure air duct 6, which is compressed in the rotor 2 by the exhaust gases coming from the engine (not shown) and leaves the charger as charging air through a high-pressure air duct 7 running perpendicular to the duct 6 and enters the engine.
  • the exhaust gas coming from the engine enters a high-pressure gas duct 9 of the gas housing 4 and flows out of it after it has released part of its energy for compressing the air in the rotor 2, through a low-pressure gas duct 10 as an exhaust gas outdoors, which is indicated by the arrow 11.
  • the rotor 2 is fixedly connected to a rotor shaft 12 which protrudes through the air housing 3 to the outside, at its free end with a belt disc 13 torsionally rigid and is supported in two bearings 14 and 15.
  • the rotor 2 is driven by the motor with constant transmission via the pulley 13, which is firmly connected to it, via a belt, preferably a V-belt.
  • FIG. 2 The modification of such a pressure wave supercharger according to the invention is shown in FIG. 2, which essentially shows only the outer mounting in the air housing.
  • a bearing flange 16 which is intended for attachment to the air housing, not shown, receives a schematically drawn roller bearing 17 on the free end of the rotor shaft 18.
  • the pulley 19 is mounted on a shaft journal 20 which is concentric with the rotor shaft 18 and which is screwed into the shaft 18 by a threaded journal 21, on two deep groove ball bearings 22 and a one-way clutch 23 arranged between them.
  • a nut 24 at the free end of the shaft journal 20 braces the two bearings 22 and the one-way clutch 23 arranged between them against the end face of the rotor shaft 18.
  • a protective cap 25 pressed into the free end of the pulley 19 prevents contaminants from penetrating into the pulley bearing.
  • FIG. 3 shows an enlarged section of the one-way clutch 23 from FIG. 2.
  • This one-way clutch of known design has rollers 26 as the clamping body, which are held by a cage 27 in such a way that they oppose each other with the play required for the clamping action and the decoupling can move the outer ring 28 in the circumferential direction.
  • the rollers 26 are pressed into the clamping position by leaf springs 29, which consist of short lobes bent from the cage, the pretensioning force being set such that an overtaking of the pulley which is inevitably driven by the motor is possible up to the range of the nominal speed. 3 does not have an inner ring, so the rollers run directly on the hardened shaft journal 20.
