Definitions

  • the present invention relates to a device for controlling the means for recirculating an engine cooling fluid, in particular for vehicles.
  • Examples of these devices are known, for example, from DE 101 58 732 and EP 1,353,051.
  • the first device in that, despite having smaller axial dimensions, it envisages, however, a magnetic induction coupling for the slower speed which is unable to achieve high values of the torque to be transmitted to the pump shaft, making the device unsuitable for high-capacity pumps such as those used in heavy vehicles, in particular of the type having a low engine rpm, but a high number of revolutions of the pump.
  • the second device instead envisages radial dimensions which, extending beyond the dimensions of the clutch rotor, said rotor being normally incorporated in the pulley connected to the driving shaft, make it difficult to house the pumps in the different engine compartments of the vehicles.
  • the technical problem which is posed, therefore, is that of providing a device for controlling the means for recirculating engine cooling fluids for vehicles and the like, which is able to produce a variation in the speed of rotation of the impeller of the said recirculating means depending on the actual operating requirement of the engine.
  • this device should have small dimensions, in particular radial dimensions, but at the same time should be able to produce high torques also at a slower speed of rotation of the engine so as to be applicable also to high-performance pumps of heavy vehicles with low-revolution engines.
  • the device should be easy and inexpensive to produce and assemble and should be able to be installed easily on the pump body without the need for special adaptation.
  • FIG. 1 shows a partially sectioned view of a first example of embodiment of the device according to the present invention
  • FIG. 2 shows a second example of embodiment of the device according to the present invention.
  • FIG. 3 shows a variation of embodiment of the device according to FIG. 2 .
  • the impeller 1 of a pump for recirculating the cooling fluid of vehicles and the like is mounted on a first end of a shaft 2 supported by a stationary assembly 10 comprising the body 11 of the pump fixed to the base 11 a of the vehicle engine.
  • the pump body 11 has, arranged inside it, a sealing bearing 12 , coaxial with the shaft 2 , and a bearing 13 , on the inner race of which the shaft 2 of the impeller is keyed.
  • the pump body 11 has, keyed onto the outside thereof, a second bearing 40 , the outer race 40 a of which is integral with a circular ring 21 which is suitably shaped and on the outer circumferential edge of which there is formed a pulley 21 a , suitable for engagement with a belt 3 for transmission of the movement to the ring 21 .
  • the circular ring 21 has an extension in the axial direction 21 b which forms the rotor of an electromagnetic coupling 20 which comprises a fixed electromagnet 22 housed inside a corresponding seat of the said rotor 21 and an armature 23 made of friction material and arranged facing the rotor 21 on the opposite side to the electromagnet and integral with a resilient membrane 24 in turn constrained to a driven element consisting of a flange 14 mounted on the shaft 2 by means of a corresponding sleeve 14 a.
  • the armature 23 is able to perform movements in the axial direction towards/away from the rotor 21 , but is locked as regards relative rotation with respect to the flange 14 .
  • a permanent magnet 60 is also envisaged, being arranged on the fixed support of the electromagnet 22 .
  • the rotor 23 also has, mounted thereon, a conductive support 32 a with a magnetizable element 32 which forms the first part of a second Foucault current induction coupling 30 , the second part of which is formed by a plurality of small magnets 31 integral with the circular flange 14 connected to the driven shaft 2 so as to be axially opposite the said magnetizable element 32 with a predetermined air gap.
  • the rotor part 21 with the magnetizable element 32 has interruptions 21 c in the magnetic conductivity of the rotor so as to cause suitable annular closing of the magnetic flux lines as shown in FIG. 1 .
  • the fact that the armature 24 is independent of the coupling 30 improves the operating conditions of the latter since dangerous contact between the magnets integral with the rotor and the support of the magnetizable elements 32 in the event of wear of the said armature is avoided.
  • the presence of the permanent magnet 60 ensures that, in the event of an electrical failure, the armature is always engaged with the rotor, ensuring recirculation of the cooling fluid (“fail safe” mode).
  • FIG. 2 shows a second embodiment of the device according to the present invention which, in this simplified form, has a flange 114 with a radial dimension substantially contained within the radial dimension of the bearing 40 and devoid of the Foucault coupling 30 .
  • FIG. 3 shows a variant of the second embodiment of the device shown in FIG. 2 ; in this configuration it is envisaged that, in addition to the reduction in the radial dimensions of the flange 114 , the electromagnet 122 is of the conventional type, resulting in ON/OFF operation with a speed of rotation and neutral of the conventional type.
