Definitions

  • the invention relates to a valve for controlling exhaust gas or fresh air in a drive unit of a motor vehicle or generator with a valve housing having a channel, with an adjustable valve body for releasing or closing a flow cross section of the channel and with an electric motor drive for adjusting the valve body.
  • valves are often used in internal combustion engines or fuel cells of motor vehicles or generators and are known from practice.
  • the duct often carries hot exhaust gas or is connected to components that are subject to high thermal loads. This high thermal load is passed on to the electric motor drive. Since the electromotive drive and components of a transmission connected to it can be thermally overloaded, water cooling is used in the valve known from practice. However, such water cooling is very expensive and requires a large amount of space.
  • the invention is based on the problem of developing a valve of the type mentioned at the outset in such a way that it can be produced at particularly low cost and has a particularly small installation space.
  • This design keeps the thermal load on the electric motor drive particularly low.
  • the thermal decoupling enables the production of independent assemblies of the electromotive drive and the valve housing. Thanks to the invention, complex and large-volume water cooling can be avoided.
  • the valve according to the invention is therefore particularly economical to manufacture and has a particularly small installation space.
  • the thermal decoupling is structurally particularly simple if the electromotive drive is arranged in a motor housing and if an insulator is arranged between the motor housing and the valve housing.
  • the isolator is an air gap.
  • the valve can be mounted particularly easily if the motor housing and the valve housing each have mutually opposite flanges and if the insulator keeps the flanges at a distance from one another. After selecting the valve housing and the motor housing, the valve can also be easily assembled in a modular system.
  • the isolator is made of plastic.
  • the thickness of the insulation makes it easy to determine the thickness of the plastic.
  • the plastic preferably has a height of at least 3 mm.
  • the isolator is structurally particularly simple if the isolator has at least one ring element for spacing the channel from the electromotive drive.
  • a ring element has the advantage that the cross section of the possible heat conduction is particularly small.
  • the insulation effect of the insulator can be easily adjusted if the wall thickness of the ring element is less than the height of the ring element.
  • the valve has a high stability with a small contact area between the motor housing and the valve housing when the motor housing and the valve housing are connected to one another via a cross support arranged away from the flange and when the cross support has an insulator.
  • a drive shaft fastened to the valve body and protruding into the motor housing is made of a thermally poorly conductive material, in particular plastic.
  • FIG. 1 schematically shows a partial area of a motor vehicle with a drive machine and a valve
  • Fig.2 enlarges the valve of Figure 1 in a per
  • FIG. 1 shows a partial area of a motor vehicle 1 with a drive unit having a drive machine 2.
  • the drive unit has two supply channels 3, 4 for fuel, for example gaseous fuel, and for fresh air and an exhaust line 5.
  • the drive machine 2 can be, for example, a fuel cell or an internal combustion engine.
  • a valve 7 which can be controlled by an electric motor drive 6 is arranged in the exhaust line 5.
  • valve 7 can also be arranged in the supply duct 3, 4 that carries fresh air or fuel.
  • Electric current generated by the drive machine 2 is fed to a control device 8.
  • the control device 8 is connected to an electrical system, not shown, of the motor vehicle.
  • the electromotive drive 6 of the valve 7 is supplied with electrical current via the control device 8.
  • a gear 9 with a position sensor 10 is arranged between the valve 7 and the electric motor drive 6. The position sensor 10 detects the position and thus the function of the valve 7.
  • FIG. 2 shows the valve 7 with the electric motor drive 6 of Figure 1 in an enlarged exploded view.
  • the valve 7 has a valve housing 11 to be mounted in the exhaust line 5 from FIG. 1 with a valve body 13 arranged therein, which can be screwed onto a drive shaft 12.
  • the valve body 13 can be adjusted by driving the drive shaft 12 and thus release a channel 14 of the exhaust line 5 or close.
  • the electric motor drive 6 is arranged together with the gear 9 shown in FIG. 1 in a motor housing 15.
  • the motor housing 15 and the valve housing 11 each have a flange 16, 17, between which an insulator 18 is arranged.
  • the insulator 18 is made of plastic and has three interconnected ring elements 19. Furthermore, the motor housing 15 and the valve housing 11 are connected via a transverse support 20 which is removed from the flanges 16, 17.
  • Cross support 20 has an insulator 21 with a ring element 22 and a screw 23, preferably made of plastic.

Abstract

L'invention concerne une soupape (7) d'une unité d'entraînement d'un véhicule automobile dans laquelle un boîtier de soupape (11) est dissocié thermiquement d'un carter de moteur (15). Les pièces d'un entraînement à moteur électrique (6) et d'un mécanisme (6), disposées dans le carter de moteur (15), sont ainsi protégées contre les sollicitations thermiques. La fabrication de la soupape (7) est peu coûteuse et l'espace de montage de la soupape est particulièrement petit.
