Definitions

  • This invention relates to a shroud and, in particular, a shroud for a motor vehicle engine cooling system.
  • Motor vehicle engine cooling systems comprise a radiator and a ventilator, usually of the axial type, designed to channel a cooling air flow against the radiator.
  • Ventilators are defined by an electric motor whose output shaft is integral with a fan comprising a hub for connection to the shaft and a plurality of blades which project from the hub.
  • a shroud is provided to support the ventilator motor and to house the fan at least partly so as to optimize heat removal by the radiator.
  • Shrouds usually comprise a main body or frame which has a main circular opening delimited by a cylindrical wall for the passage of a cooling air flow.
  • the frame comprises a ring for mounting the motor of the ventilator which is supported by a plurality of arms which project from the cylindrical wall towards the inside of the opening itself.
  • the mounting ring is coaxial with the cylindrical wall and the motor is mounted coaxially with the mounting ring.
  • the frame has a plurality of secondary openings, each provided with a panel by which it is closed and which is connected by a hinge to the frame at the respective opening.
  • the panels are free to open to facilitate the passage of air through the secondary openings.
  • the cooling air flow is produced by the fan and passes through the main opening, whereas when the speed of the vehicle increases, the cooling air flow is produced by vehicle motion and passes through all the openings of the shroud.
  • the hinge connection is defined by a pair of coaxial pins which are aligned along a direction transversal to the shaft of the electric motor and which project from the perimeter of the respective opening towards the inside of the opening.
  • Each of the panels has a pair of hooks and each hook is designed to engage a corresponding pin to define the aforementioned hinge.
  • the moulding production process may result in material shrinkage which may in turn lead to the pins of a secondary opening not being coaxial.
  • the portion of the frame where the secondary openings are made is not necessarily flat and this leads to further difficulties in obtaining coaxial pins.
  • Axial misalignment of the pins implies difficulties in hooking the panels to them during assembly and, even when the panels are hooked to the pins, causes resistance to panel rotation.
  • the resistance caused by non-coaxial pins may be such that the panel does not open or opens only partly, making it more difficult to cool the radiator.
  • the main purpose of the present invention is to propose a shroud which is free of the above mentioned disadvantages.
  • the aim of this invention is to provide a shroud in which the panels can be easily assembled to the frame.
  • Another aim of the invention is to provide a shroud where the panels for closing the secondary openings are free to move, as a function of vehicle speed, between the closed position and the open position.
  • FIG. 1 is a schematic front perspective view of a shroud according to this invention
  • FIG. 2 illustrates the shroud of FIG. 1 in a schematic rear perspective view
  • FIG. 3 is a schematic rear perspective view showing a detail of the shroud of FIGS. 1 and 2 in a second operating configuration
  • FIG. 4 is a schematic front face view of the detail of FIG. 3 .
  • the numeral 1 denotes a shroud according to this invention.
  • the shroud 1 which has a front face 1 a and a rear face 1 b , comprises a frame 2 with a main opening 3 delimited by a main wall 4 , preferably cylindrical, and at least one secondary opening 5 , delimited by a secondary wall 6 , for the passage of a cooling air flow.
  • the shroud 1 has seven secondary openings 6 which, for the purposes of this invention, can be considered substantially coplanar with the main opening 3 .
  • the shroud 1 comprises a mounting system 7 for a ventilator, not illustrated, associated with the frame 2 and designed to support the ventilator at the main opening 4 .
  • the mounting system 7 comprises a ventilator mounting ring 8 which is coaxial with the main wall 4 .
  • the mounting system 7 comprises a plurality of arms 9 which extend from the main wall 4 to the mounting ring 8 to support the mounting ring 8 itself.
  • the shroud 1 comprises, for each secondary opening 5 , a respective panel 10 for closing the same.
  • the panel 10 is connected to the frame 2 rotatably about an axis R and is movable between a lowered position, illustrated in FIGS. 1 and 2 , and a raised position, illustrated in FIG. 3 .
  • the panel 10 closes the corresponding secondary opening 5 whilst in the raised position, it allows a component of the cooling flow to pass through the secondary opening 5 itself.
  • the opening angle ⁇ of the panel 10 depends on the speed of the vehicle the shroud 1 is installed in.
  • the shroud 1 is mounted in such a way that its front face 1 a is directed forwards in the direction V of vehicle movement.
  • the air or pressure created by the forward movement of the vehicle when it exceeds a predetermined threshold, lifts the panels 10 to the raised position, whereas, when the speed decreases, the force of gravity closes them by causing them to return to the lowered position.
  • the shroud 1 comprises hinge means, which define the axis of rotation R and which operate between the frame 2 and the panel 10 .
  • the hinge means comprise a pin 11 extending through the secondary opening 5 and having a first and a second end 11 a , 11 b respectively connected to a first and a second section 6 a , 6 b of the secondary wall 6 on opposite sides of the pin 11 .
  • the pins 11 are made as one with the frame 2 , in particular during moulding.
  • the pin 11 extends in a direction transversal to the direction of forward movement V in such a way that the motion of the vehicle generates a pressure which lifts the panel.
  • the panel 10 is equipped with a pair of hooks 12 a , 12 b designed to grip the pin 11 idly.
  • the hinge means comprise first engagement means, embodied by way of an example by the pin 11 and associated with the frame 2 , and second engagement means, for example the hooks 12 a , 12 b , associated with the panel 10 , which are connectable to each other to define a hinge connection.
  • the shroud 1 comprises, for each secondary opening 5 , a single pin 11 which extends between two opposite sections or portions 6 a , 6 b of the secondary wall 6 and which defines the axis of rotation R about which the panel 10 moves.
  • the panel can rotate freely and easily according to the speed of the vehicle
  • the pin 11 is substantially horizontal, in particular considering a shroud 1 installed in a vehicle.
  • the secondary wall 6 comprises an upper edge 13 , a lower edge 14 and a first and second lateral edges 15 , 16 and, in particular, is substantially rectangular in shape.
  • the pin 11 extends between the lateral edges 15 and 16 , its first end 11 a being integral with the edge 15 and its second end 11 b integral with the edge 16 .
  • the pin 11 is parallel to the upper and lower edges 13 , 14 of the secondary wall 6 .
  • the pin 11 is slightly offset towards the upper edge 13 and thus slightly further from the lower edge 14 , so that most of the weight of the panel 10 contributes to closing it when the speed decreases.
  • the hooks 12 a , 12 b are preferably spaced on the panel 10 .
  • the hooks 12 a , 12 b are preferably positioned on the panel 10 in such a way as to engage the pin 11 substantially at the ends of it 11 a , 11 b.
