Abstract

A radiator grille positioned in the vehicle bodywork (2) above or below (not shown) the vehicle bumper (3) consists of an assembly of louvres fixed (12) and movable (13) which operate to open and close the main air inlet for cooling airflow (7) to the radiator (8) a second smaller fixed air inlet aperture (6) also provides cooling airflow (7). The movement of the louvres (13) is governed by a sensor (23) of the engines coolant temperature. The movable louvres (13) remain closed for certain conditions such as high speeds and warm up periods until the engine coolants temperature determines their operation. A smaller body (11) of fixed slats forward of the assembly of fixed and movable louvres (12) (13) assumes the styling profile of the vehicle. <IMAGE>

Description

SPECIFICATION Vehicle radiator grille with shuttered operation This invention relates to the cooling of vehicles.
When a vehicle is in operation during periods of poor weather conditions with low ambient temperatures also during high road speeds, it is known that the radiator of the vehicle is supplied with a surplus of cooling air to the vehicles cooling systems requirements. To control this problem covering of the radiator grille or the main intake area is usually accomplished by fitting a radiator grille muff or by a covering of foil. The described method of covering has a disadvantage in that once the engine has reached a high temperature the radiator requires an amount of cooling air thus the covering needs to be manually removed to avoid overheating. Later the covering material will need to be placed back to retain its advantages.
The designs enclosed within take into account the advantages of covering the radiator grille or intake area and also resolve the problem of overheating once the covering material is not required.
According to the invention there is a vehicle provided with a radiator grille in a position located at the front of the vehicle body, above the vehicles bumper or below the vehicles bumper. Said radiator grille consists of a series of vanes with much the same appearance as a conventional radiator grille, which provide an inlet for cooling airflow to the radiator of the engine.
The top vane of said radiator grille is fixed after which each alternate vane is movable by pivoting around a central axis.
The movement by the movable vane is between an open position which allows airflow through the aperture above and below said vane, and a closed position in which said movable vane rotates to contact the fixed slat above and below thus preventing airflow by means of a physical shield.
Actuation of said movable vanes is by an electrical solenoid which is governed by an electrical sensing circuit with the ability to monitor the cooling systems temperature and its change in temperature. In accordance with this when the engines coolant is below a predetermined temperature range said solenoid actuates said movable vanes to said closed position to prevent airflow through the apertures of said radiator grille. When the engines coolant reaches a predetermined temperature range said solenoid actuates said movable vanes to said open position to allow entry for cooling airflow through said radiator grille on to the radiator.
Many existing radiator shutter designs are such that each vane is movable around an axis. The shuttered radiator grille described here within is such that each alternate vane is movable around an axis in order to reduce manufacturing costs, design complexity, and reduce the susceptibility to breakdown due to siezure of linkage and shafts.
Fixed to the front of the main body of vanes is a smaller body which has a series of corresponding slats that extend outwardly, the smaller body is designated the styling grille.
The said styling grille has certain cosmetic advantages as the styling of said grille can assume the styling profile of the vehicles front. Said styling grilles addition replaces the appearance of the necessary straight front edge of said movable vanes and to a certain degree hides the appearance of said movable vanes when said closed position is adopted. A ribbed capping to each end of said styling grille extends said radiator grille across the vehicles frontage to provide a iesser degree of extension required by the vanes. Vertical strips or other details can be added to the said styling grille if marketing requirements are such.
A second smaller additional air inlet in said vehicles frontal bodywork, provides a cooling airflow to the radiator, at the first instance, to maintain normal engine coolant tempratures following a warm up period and during high vehicle speeds without the opening of said radiator grille vanes.
During the periods of time said radiator grille functions in said closed position underbonnet air pressurisation is substantially prevented thus reducing the aerodynamic drag on the vehicle.
The invention will now be described with reference to the accompanying drawings in which Figure 1 is a fragmentary sectional view along line 1-1 longitudinally through the vehicle according to the invention.
Figure 2 is a fragmentary sectional view longi through the vehicle.
Figure 3 is a fragmentary front view of the Radiator grille assy.
Figure 4 is a side view of the shutter grille assy, Figure 5 is a fragmentary plan view of the grille assy.
Figures 6 a view of a movable vane.
Figure 7 is a bottom view of a movable vane.
Figure 8 is a fragmentary cross section along line 2-2.
The vehicle radiator grille is located at front of the vehicle body 2 above the bumper 3 occupying a body aperture 4A between the headlamps as (Fig. 1).
Alternatively according to the vehicles styling located beneath the bumper 3 as (Fig. 2) occupying an aperture 4B in the downward and rearward extending apron panel 5.
A second additional air inlet 6 in the vehicles frontal bodywork 2, for the radiator 8, should preferably be located behind the vehicles bumper 3 and number plate (not shown) as the highest majority of the cooling air 7 intake for the radiator 8 is to be via the radiator grille 1.
The radiator grille assy 1 consists of three substantial components namely the main body 9, the assy of movable vanes 1 3 and the styling grille 11 (Fig. 3). The series of vanes of the radiator grille 1 belong to the main body 9, the upper vane 1 2 of the series is a fixed member of the main body after which each alternate vane 1 3 is movable by pivoting around a central axis (Fig. 1). The method of pivoting is by a shaft 14 at each end of the vane 1 3 rotating in a bore 1 5 set within a bearing block 1 6 retained within the main body 9. The vane shafts 14 and bearing blocks 16 are moulded in a plastic with a low coefficient of friction and a hard wearing surface.A rubber seal 1 7 at each end of the bore 1 5 prevents the ingress of dirt. (Fig. 5).
The spacing between each vane is such that the movable vanes 1 3 have only moderate amount of movement to accomplish between the open position and closed position. The open position comprising of the series of vanes 12, 1 3 parallel in relationship to each other, provides passage of ambient cooling air 7 through the apertures 18 between the vanes 12, 13 to the radiator 8. The closed position comprising of the alternate movable vanes 1 3 rotating to a position in which the forward periphery edge 1 9 of the movable vane contacts the upperside of the fixed vane 1 2 beneath, and the rearward periphery edge 20 contacts the underside of the fixed vane above, thus preventing airflow by virtue of a physical sheild (Fig. 1).An adhesive rubber strip (not shown) applied to the contacting faces of the movable vane acts as a seal when the vane is in the closed position. Preferably the length of the movable vane (1 3) should be that of the radiator.
The actuation of the movable vanes 1 3 is by an electrical solenoid 21 governed by an electrical circuit (not shown) which comprises of a sensing means sensitive to the engine coolants temperature and its change in temperature, in order to actuate the movable vanes 1 3 at a predetermined temperature range. The sensor 23 is preferably mounted in the bottom of the radiator 8 alternatively in the thermostat housing of the engine. The operation of the fan 24 should be permissable once the movable vanes 1 3 operate to the open position if the performance of the cooling system required its operation (Fig. 1).
The actuated movement of the movable vanes by the solenoid 21 (Fig. 4) is via a siotted wheel 25 attached to one end of the vane, the slot 26 compensates for the conversion of straight line movement to tangential movement of the vane. Movement of the movable vanes is simultaneous by means of straight links 27 attached to individual vane driving wheels 28 to each end of the movable vane. The links 27 are free to rotate on pivot pins 29 which are integrally moulded to the vane driving wheels 25, 28 to retain the links 27 on the pivot pins 29 the pin heads are preferably stamped to increase the pin face over a larger diameter.
A minor assembly of the movable vanes 13 occurs before assembly to the main body 9.
The integral moulding of vane and pivot shaft 14 retains the bearing block 1 6 to the pivot shaft 14 by pressing the driving wheel 25, 28 on to the end of the shaft. A corresponding flat edge on the shafts and wheels 25, 28 prevents wheel rotation on the shaft. The movable vane are linked together by the assy of the integral pivot pin 29, the driving wheels 25, 28 and the straight link 27 (Fig.
5).
A movable vane 1 3 made from a periphery profile moulding does not provide sufficient stiffness to overcome deformation of its profile by the force of the oncoming ambient air at high vehicle speeds. The two designs illustrated are different methods of reinforcing the movable vane 1 3 without incorporating a very large profile. Shown in (Fig. 7) a crosshatching pattern of stiffening ribs 30 on the underside of the vane moulding is incorporated as reinforcement. The movable vanes 1 3 have integral or separate pivot shafts 14 are moulded from suitable plastic.
Shown in (Fig. 6) is a double skin profile 34 extending from the centre to the rear edge of the vane 13 is incorporated. A series of ribs 35 spaced along the longitudinal length of the vane between the double skin 34 stiffen the vane moulding. To the front a series of external ribs 36 spaced along the longitudinal length provide additional stiffness.
The-main body 9 moulded from a general application plastics (Fig. 5) consists of the fixed vanes 12 with integral housings 41 to each end which retain the bearing blocks 1 6 of the movable vanes 1 3. A series of stiffening ribs 42 spaced along the longitudinal length are moulded to the back of the main body to avoid encroachment of the movable vanes 13 (Fig. 1). But extend inwardly in the regions 43 just below each vane 1 2, 1 3 and along the regions 44 of the upper and lower faces of the fixed vanes 1 2 (Fig. 1). Additional ribs 45 extend longitudinally to link the main body ribs 42 together. The integral rectangu lar housing 41 incorporates a wall 46 which provides recesses 47 to retain each vane bearing block 16 within the main body 9- (Fig.
8).
The styling grille 11 moulded from a general application plastics consists of a series of fixed parallel slats 48 with rectangular cappings 49 integral to each end. The styling grille slats 48 correspond to those of the main bcdv of vanes 12, 1 3. A series of ribs 50 between the slats spaced along the longitudinal length provide the moulding with stiffness. In (Fig. 1) the detail of the ribs 50, in the area that abuts the main fixed vane 12, extends inwardly to form a notch 51 between the rib 50 and the slat 48 of the styling grille.Upon assembly the main fixed vane 1 2 locates in the notch 51 to prevent flexing of the frontal area of the fixed vane 1 2. For continuity of appearance, at the point at which the styling grille slats 48 join the capping 49, ribs 54 continue on the face of the outwardly extending capping 49.
Fastening of the styling grille 11 to the main body 9 retains the minor assembly of movable vanes 1 3 and bearing blocks 1 6 located in the respective recesses 47 of the main body housing 41. Fastening is by a snap fitting of a number of circular prongs 52 (Fig.
9), moulded on the inside face of the capping 49, into corresponding holes 53 in the facing wall 46 of the main body housing 41. Alternatively (Fig. 8), a nutsert 59 moulded on to the inside face of the capping 49 retains a fastening screw 58. Second alternative (Fig.
8) a plastic rivet 56 inserted from the outside face of the capping 49 provides the fastening means. A round plug 57 is pushed over the top of the plastic rivet 56 to retain a flush surface.
