Definitions

  • the invention relates to a throttle device according to the preamble of the main claim.
  • a throttle valve is known for example from EP 04 98 933 A1. This is integrated in a housing that can be attached to a carrier body.
  • the housing is designed in the manner of a throttle valve assembly, i. H. the connection piece is fastened on the one hand to the carrier body and on the other hand to the intake system of an internal combustion engine.
  • WO 91 05 152 a throttle device for reducing the gas exchange losses in an internal combustion engine.
  • This throttle device is also a separate component which, on the one hand, must be connected to the intake tract of an engine and, on the other hand, to an air-guiding system.
  • a disadvantage of this known device is the high Assembly effort and the large number of individual parts, which must be assembled into a unit when assembling the throttle device.
  • the endeavor can be recognized to produce complete systems that achieve this goal.
  • the invention is therefore based on the object of providing a throttle device which requires little assembly effort and simplifies the maintenance of the system. This object is achieved on the basis of the preamble of the main claim by its characterizing features.
  • Plastic in particular, due to the lower modulus of elasticity, sometimes results in significantly lower specific material stresses due to the greatly increased contact surface as a result of deformation than with steel pairings.
  • Plastic also has other interesting properties, e.g. B. corrosion resistance, the high mechanical damping, an extremely low coefficient of friction, less wear, low specific weight, good workability and low finished part costs in mass production.
  • B. corrosion resistance the high mechanical damping
  • an extremely low coefficient of friction less wear
  • low specific weight good workability and low finished part costs in mass production.
  • the latter suitability of plastics for cost-effective finishing, which is most striking in injection molding of complicated parts, makes them superior to other materials.
  • throttle valves or throttle devices were usually made of metal and arranged between a plastic air filter and a plastic suction system.
  • the modular design of the throttle valve allows the
  • An advantageous embodiment of the invention provides for the throttle valve to be provided with a two-part shaft. This has the advantage that, in addition to facilitating assembly, two separate modules can also be present on the shaft parts. It is advisable to arrange the position sensor on one shaft part and the actuating unit on the other shaft part.
  • the housing of the throttle valve module into a connection.
  • the connecting element between an air filter outlet and a suction system inlet simultaneously represents the throttle valve module.
  • FIG. 1 a preassembled throttle flap on day module
  • FIG. 2 shows a throttle valve plug-in module
  • FIG. 3 shows a variant of a preassembled throttle valve module
  • Figure 4 shows a throttle valve module
  • the assembly module 10 consists of a throttle valve 11 which is provided with two bearing parts 12, 13.
  • a position tap or position sensor 14 is arranged on the bearing part 12, and the receptacle 15 for the Bowden cable, not shown here, is located on the bearing part 13.
  • the entire assembly module 10 is hooked into the connecting flange 16 of a suction pipe.
  • a connecting flange 17, which represents the clean air outlet of the air filter, is slipped over the mounting module 10 and thus forms the fastening device for the mounting module 10 in connection with the connecting flange 16.
  • This assembly module is particularly easy to seal.
  • the connecting flange 16 or connecting flange 17 can have a circumferential groove for a sealing rubber.
  • the bearings and additional seal can be pre-assembled, as can the throttle valve with the two side parts.
  • the two connecting flanges 16, 17 can be constructed according to the system of constant wall thicknesses.
  • the assembly module can be replaced or repaired at any time using a detachable connection technology.
  • the throttle valve 11 is sealed in the connecting flange 16 by means of suitable sealing beads which are provided in the connecting flange 16
  • a throttle valve module with split throttle shafts is shown.
  • the throttle valve is inserted into the throttle valve connector 18 and fixed on the half-shafts by mounting the two modules.
  • this throttle valve module is to be seen in the fact that the individual modules, such as. B. the module 19, can be easily replaced.
  • the correspondingly adapted modules can be installed in the manner of a modular system for different series.
  • FIG. 3 shows a preassembled throttle valve module 23 which is fastened between the connecting flange 24 and the connecting flange 25. While the connecting flange 25 represents the output side of the air filter, the connecting flange 24 is connected to the intake manifold side of the engine.
  • the throttle valve module 23 comprises the throttle valve 26 and the throttle valve shaft 27 and the bearing 28. The position sensors arranged on the shafts and the actuating device for the throttle valve are not shown here.
  • FIG. 4 shows a throttle valve module, which is inserted into a suction system connection piece 29.
  • Throttle valve module 30 consists of a throttle valve connector 31, in which the throttle valve 32 is arranged.
  • a position transmitter 33 is located on one side of the plug-in module 30, and the position sensor 34 is located on the opposite side.
  • This plug-in module has the advantage that different versions can be installed in the existing installation space without the module concept having to be changed.
  • the preassembled throttle valve module is connected to the suction system connection piece 29 via a suitable sealing system.
  • This version also has the advantage that the entire module can be replaced very quickly.

Abstract

Un dispositif d'étranglement, notamment un papillon des gaz monté dans le canal d'aspiration d'un moteur à combustion interne comprend un corps, une commande (15) de papillon des gaz, un capteur de position (14) et un papillon (11) assujetti à un arbre de papillon. Le dispositif d'étranglement est monté entre le raccord (17) du filtre à air du côté d'entrée d'air frais et le tuyau d'aspiration (16) du moteur à combustion interne. Le raccord du filtre à air et/ou le tuyau d'aspiration sont en plastique et les éléments individuels du dispositif d'étranglement constituent des modules qui peuvent être assemblés par emmanchement, par vissage ou par serrage.
