Definitions

  • the invention relates to a throttle valve unit for use in the exhaust system of an internal combustion engine, comprising a valve body, a shaft rotatably mounted therein about an axis with a closure element, a vacuum unit with a membrane and one of the implementation of the lifting movement of the membrane in a rotational movement of the shaft serving coupling device, wherein a rotational movement of the shaft in the flap position "open" limiting stop means is provided.
  • Throttle valve units are known in particular from engine construction.
  • the main application area for throttle valves is the regulation of the combustion air or the fuel air mixture.
  • the temperature of the flowing medium is at the level of the ambient air temperature of -20 ° C to + 40 ° C.
  • the structure and operation of the extent known throttle valve units is z. In DE 197 29 648 A1 . DE 40 27 269 A1 . DE 42 09 586 A1 . DE 100 06 795 A1 . DE 199 28 473 A1 . DE 198 57 957 A1 and DE 43 13 454 A1 described.
  • a planar closure element which is arranged on a housing passing through the rotatable shaft.
  • the shaft is guided in plain bearings.
  • the actuating forces are initiated from the outside. It is used for vacuum or electric drives.
  • Throttle valve units but also in exhaust systems of internal combustion engines are becoming increasingly important. she Especially in connection with mufflers with variable damping characteristics and the variable design of the mouth noise used (see. E. Santiago u. A., reprint MTZ 53 (1992) Issue 7/8 ; Ch. L generallygen u. A., System Partners 2000 pp. 54-57 ). Due to the high temperatures in the environment of exhaust systems used here mainly flaps with vacuum box. The externally introduced negative pressure, which depends on the respective operating state of the engine, acts on a membrane, which is connected to a linkage. A lifting movement is generated when vacuum is applied. When no negative pressure is applied, a spring disposed in the vacuum box generates a restoring force; the membrane returns to its original position (cf.
  • the lifting movement of the linkage acts via a crank drive on the shaft and the closure element.
  • the crank mechanism converts the lifting and return movement of the diaphragm and linkage into a rotational movement of the shaft.
  • the vacuum unit is generally arranged by means of a bracket or a mounting bracket on the valve body.
  • the stroke limiter can be specified by a stop acting on the membrane, or it is done by means of a stop for the crank mechanism.
  • the temperature of the exhaust gases of internal combustion engines is, however, partly above 850 ° C.
  • the high temperatures lead to the thermal expansion of all components. Associated with this are changes in shape, length and position, changes in distances and spring stresses.
  • a throttle valve assembly which is mounted with the usual tolerances at an ambient temperature of 20 ° C, changes their switching behavior seriously with such rising temperatures. Frequently, a flap which closes smoothly at ambient temperature will bite and / or close at such high operating temperatures and / or no longer completely close. The conditions of use of flaps in exhaust systems therefore require much greater tolerances between the pairs of bearings than at ambient temperature level.
  • the noise problem namely the rattling of the moving components by vibration excitations in a hot gas application thus can not be resolved.
  • the technical contradiction is the following: Although a slight clearance between moving components reduces the risk of the formation of rattling noises. However, the risk of seizure increases at high operating temperatures. A big game between the moving parts counteracts the seizure, but leads to rattling noises. And spring-loaded friction devices increase the required actuating forces in an unacceptable manner.
  • the object underlying the present invention is to provide a throttle valve device of the type specified, which is characterized by a high level of reliability (no jamming!) And low required restoring forces due to minimal noise.
  • the throttle device according to the invention is characterized characterized in that the stop device is designed as an axially acting clamping device comprising a stationary clamping element, a rotatably moved with the shaft clamping element, an axially stationary Hubanschlagelement and with the shaft axially moving Hubanschlagelement, wherein at least one of the two clamping elements inclined to the axis Has control surface on which in the flap position "open” the other clamping element is present, and wherein in the flap position "open” the moving Hubanschlagelement rests against the stationary Hubanschlagelement.
  • the closure element and the shaft comprehensive unit is clamped with the throttle open, ie fixed in such a way that they can perform within the flap housing no leading to rattling noise movements.
  • the mechanical vibrations of the exhaust system or the pulsations of the exhaust stream - neither rattling noises between the shaft and bearing, nor between the closure element and the valve body.
  • the throttle valve unit according to the invention sufficiently large tolerances between the moving components are possible to compensate for the manufacturing tolerances and deformations due to temperature change and not to hinder the movements even with decreasing lubrication.
  • only a very small force is required to actuate the flap, which accommodates the limited space available and the limited resources available in vehicles.
  • the coupling device comprises a link connected to the membrane of the vacuum cell and a link connected to the shaft crank arm, wherein the rotatable clamping element is part of the crank arm.
  • the shaft is mounted in the valve housing by means of two plain bearings.
  • These may be formed from a wire mesh according to a development of the present invention. This is particularly favorable with regard to the sliding properties in the relevant application of the throttle valve unit in the exhaust system of an internal combustion engine.
  • plain bearings another preferred development of the invention is characterized in that at least one of them is designed as a federal government bearing, which is supported in the axial direction outwardly on the valve body.
  • the collar of the federal plain bearing can slightly protrude into the interior of the valve body and forms the stationary Hubanschlagelement.
  • the moving Hubanschlagelement is particularly preferably formed by a collar or a shoulder of the shaft.

On the side flanks a game is provided. This clearance, which is smaller than the axial extent of the at least one inclined surface of the clamping elements, is used for the (small) axial displacement of the unit comprising the shaft and the closure element during clamping at the end of the opening movement.

  • the valve body 1 and the bearing bushes 2 form the carrier for all other modules.
