Definitions

  • the invention relates to a valve device for an internal combustion engine with a flow housing defining a flow channel, a valve body which is rotatably disposed in the flow channel, a valve shaft on which the valve body is mounted, an actuator having an actuator output shaft which is connected to the valve shaft on a common Rotary axis arranged and rotatably coupled to the valve shaft and an actuator housing in which the actuator is arranged.
  • flap devices are used, for example, as exhaust gas flaps or exhaust gas recirculation valves in low-pressure or high-pressure exhaust gas circuits or as throttle valves in the intake tract of internal combustion engines and serve to control an amount of exhaust gas attributable to the cylinders or to regulate the pressure in the exhaust gas recirculation channel to reduce the pollutant emissions of the engine or to control the intake air quantity ,
  • the Aktorausgangswelle and the flap shaft sections project into each other, wherein axially within the mutually projecting portion, the flap shaft and the Aktorausgangswelle are radially surrounded by a driver on the inner circumference of a profiled cam surface is formed, which positively corresponds to the profiled cam surface on the outer circumference of the interengaging portion of the valve shaft and the output shaft formed, profiled shaft portion surface engages, a connection between the two shafts can be made by placing the actuator housing with the Aktorausgangswelle on the flow housing with the valve shaft. In the process, the sections projecting into one another after mounting dive into one another. The heat transfer from the flow channel via the valve shaft in the actuator housing is significantly reduced by the reduced contact surfaces between the two waves.
  • an axial bore is formed at the end of the actuator output shaft or the flap shaft into which the end of the opposite flap shaft or actuator output shaft protrudes.
  • the protruding into the axial bore portion of the valve shaft or Aktorausgangswelle is cylindrical segment-shaped and has at least one straight, axially extending cutting edge, which serves as a torque transmitting surface.
  • the driver is designed so that it has a recess on the inner circumference, which is formed in the shape of a cylinder segment, wherein the axially extending straight surface of the cylinder segment has a distance from the axis of rotation, which corresponds to the distance of the cutting edge of the output shaft and the flap shaft. Accordingly, a torque of the actuator output shaft is transmitted to the form-fitting connected driver and from there to the flap shaft, wherein each of the straight cutting edge is used for torque transmission.
  • the driver is axially loaded by a compression spring against a stop, whereby the driver is also fixed axially.
  • the driver serves as a thrust washer for one of the bearings and the bearing by the spring force of the compression spring is loaded against a shoulder of the housing. This bearing is thus secured axially. Narrow manufacturing tolerances are accordingly not observed in the axial direction.
  • the driver fulfills two functions simultaneously, so that components can be saved.
  • the driver opposite axial end of the compression spring abuts against a shaft shoulder.
  • the compression spring can rotate correspondingly with the shaft and the driver, whereby wear on the spring is avoided and a sliding surface is present only between thrust washer and bearing.
  • a second stop disk fixedly arranged on the shaft is loaded against the second bearing, whereby the position of the flap in the channel is determined.
  • the driver is connected via a press fit or by welding with the Aktorausgangswelle in which the bore is formed.
  • the driver can be preassembled on the actuator output shaft, whereby the assembly by simply plugging the housing and thus the waves can be performed on each other.
  • the flap shaft is preferably mounted in a bearing receptacle formed in the flow housing via a first bearing, and the actuator output shaft is mounted via a second bearing which is arranged in the actuator housing in a bearing receptacle. So both flaps are pre-assembled and stored on the one hand before mounting the flow housing on the actuator housing and on the other hand, after mounting a one-sided mounting of the assembled shaft via two bearings, which can be reliably absorbed on the flap bending moments.
  • a flap device for an internal combustion engine with the heat input over the flapper shaft is reduced in the actuator by reducing the bearing surfaces.
  • a rotatable connection between the Aktorausgangswelle and the flapper shaft is created reliably with easy to manufacture components that can be produced by simply plugging the two waves to each other.
  • the connection can be made largely free of play, so that a precise adjustability of the flap in the channel and thus good controllability can be achieved. In this case, production costs are reduced by simple assembly and simple production of the individual parts with small tolerances to be maintained.
  • FIG. 1 shows a side view of a flap device according to the invention in a sectional view.
  • FIG. 2 shows a cross section through the Aktorausgangswelle and the flap shaft in the region of the driver.
  • the flap device according to the invention has a flow housing 10 which delimits a flow channel 12.
  • a flap body 14 is arranged, via which the flow cross-section of the flow channel 12 can be controlled by the flap body 14 is rotated in the flow channel 12.
  • the flap body 14 is mounted on a flap shaft 16 which projects through the flow housing 10 into the flow channel 12.
  • a rotation of the flap body 14 is initiated by an actuator 18.
  • This actuator 18 is arranged in an actuator housing 20, which is closed by a cover 22 with the interposition of a seal 23 and which is connected to the flow housing 10.
  • the actuator 18 has an actuating means such as an electric motor, the movement of which is transmitted, for example, via a gear 24 geared to a driven gear 26.
  • This output gear 26 is mounted on an actuator output shaft 28 which extends from the actuator 18 in the direction of the flow housing 10 and in particular in the direction of the flap shaft 16.
  • a hollow cylindrical projection 30 is formed on the flow housing 10, through which the flap shaft 16 protrudes into the actuator housing 20 and which also extends in the direction of the actuator housing 20.
  • a circumferential groove 32 is formed on the outer circumference of the projection 30, a circumferential groove 32 is formed.
  • the hollow cylindrical projection 30 bears with its outer circumference radially against an inner wall of a hollow cylindrical receiving element 34 of the actuator housing 20, which thus radially radially surrounds the projection 30 over a defined height, wherein the groove 32 is formed within this surrounded by the receiving element 34 portion of the projection 30 , This portion surrounding the projection 30 of the receiving element 34 serves as a receiving opening 36 for the projection 30.
  • This design has the advantage that no splashing from the outside through the gap between the outer wall of the projection 30 and the inner wall of the receiving element 34 into the interior of the actuator housing 20 can penetrate.
  • the flap shaft 16 is supported by a first bearing 52 which is arranged in a first bearing receptacle 54 which is formed in the hollow cylindrical projection 30 axially between a flow channel 12 bounding the housing wall 56 of the flow housing 10 and formed on the inner wall of the projection 30 paragraph 58 ,
  • a thrust washer 60 is fixed, which bears against the bearing 52, which is preferably designed as a carbon-graphite sliding bearing.
  • a shaft shoulder 62 is formed, from which the flap shaft 16 extends with reduced diameter in the direction of Aktorausgangswelle 28 and against which a compression spring 64, whereby the flap shaft 16 is loaded in the direction of the flow housing 10 and thus the thrust washer 60th is pressed against the bearing 52.
  • the bearing 52 is positioned axially and on the other hand the flap 14 is axially positioned in the flow channel 12.
  • the flap shaft 16 in its further course a profiling in the form of an axially extending cutting edge 66 which extends from the end of the flap shaft 16 in the direction of the flow channel 12, so that the flap shaft 16 is formed in this segment 68 cylinder segment.
  • the cylinder-segment-shaped section 68 protrudes into an axial bore 70 of the actuator output shaft 28.
  • This also has a profiling in the form of an axial at its end facing the flow channel 12 extending cutting edge 72, so that this portion 74 of the actuator output shaft 28 is formed in a hollow cylinder segment.
  • Both cut edges 66, 72 are at the same distance from the common rotary or central axis 50 and are aligned with one another such that the two cut edges 66, 72 form a common straight profiled shaft section surface 77 via a common axial section 75.
  • the two shafts 16, 28 radially surrounded by a driver 76, on the inner circumference of a profiled corresponding cam surface 78 is formed in the form of a cylinder-shaped recess 79, so that a straight surface 81 is formed on the inner circumference, which is also the has the same distance from the axis of rotation 50, so that a relative rotation of the two shafts 16, 28 is prevented from each other.
  • the driver 76 also serves as a thrust washer for a second bearing 80 in which the Aktorausgangswelle 28 is mounted and which is arranged in the hollow cylindrical projection 44.
  • the compression spring 64 is located with its shaft shoulder 62 opposite end against the driver 76 axially, so that serving as thrust washer driver 76 is pressed against the serving as a stop second bearing 80, which in turn is loaded against the shoulder 48 of the projection 44.
  • the actuator 18 is actuated and thus the actuator output shaft 28 is rotated in the bearing 80, its rotation is transmitted to the driver 76 via the contact surface of the cut edges 72, 78.
  • the driver 76 transmits this rotational movement again by positive engagement via its driver surface 78 and the cutting edge 66 on the flap shaft 16, so that the flap 14 is rotated in the flow channel 12.
  • the axial position of the two shafts 18, 26 is determined by a combined rotary and compression spring 82 which surrounds the projection 44 and on the one hand abuts against the output gear 26 and on the other hand against a bottom of the actuator housing 20.
  • the driver 76 which is connected to the actuator output shaft 28, for example via a press connection, is pressed against the second bearing 80.
  • two end legs of the spring 82 grip in a known manner so behind in the figures unrecognizable projections on the actuator housing 20 and the output gear 26 that the Aktorausgangswelle 28 is biased in one direction at least during rotation from the rest position. Accordingly, the positively coupled via the driver 76 shafts 16, 28 and thus the flap 14 are rotated due to the spring force in case of failure of the actuator 18 in a Notlaufposition.
  • the actuator output shaft 28 surrounding a sealing ring 84 is arranged, which rests axially from the opposite side to the second bearing 80 against the third shoulder 48 and the shaft passage additionally seals in the direction of Aktorinnenraums.
  • the actuator 18 with the actuator output shaft 28 as well as the flow housing 10 with the flap 14 and the flap shaft 16 can be preassembled.
  • the driver 76 is attached via a slight interference fit or by welding at the end of Aktorausgangswelle 28 and the spring 64 is attached to the end of the flap shaft 16. Now, if the actuator housing 20 is pushed onto the flow housing 10 by the receiving element 34 is pushed onto the projection 30 of the flow housing 10 and against the stop on the shoulder 42, penetrates the same valve shaft 16 with its profiled end into the bore 70 of the Aktorausgangswelle 28 and it a positive connection to the driver 76 is produced.
  • the final attachment of the actuator housing 20 on the flow housing 10 is then carried out via two vertically aligned non-visible screws, which are screwed through receiving holes on connecting plates 84 which are fixed to the flow housing 10, for example by welding, into corresponding threaded holes in the actuator housing 20.
