The invention relates to a hood assembly for motor vehicles between the trunk or Engine compartment and the bulkhead a separate space to accommodate auxiliary equipment, such as Steering gears, heat exchangers, windshield wiper motors and the like.

Such hood arrangements are known. They have the disadvantage that they are in the separate room housed auxiliary equipment, especially if the hood, for example, on that of the windshield facing side is hinged, are very difficult to access. In addition, must be In these embodiments, the engine hood or trunk hood is also made longer by the amount which is the length of the space for the auxiliary equipment is equivalent to. This requires the arrangement of relatively stable joints and strong ones Compensating springs for the opened hood.

There are also motor vehicles already known in which between the engine compartment and bulkhead a tool container that can be covered by a separate hood is provided. Such an embodiment is, apart from the fact that it differs from the genus mentioned above, also disadvantageous, because the additional one provided there about an axis lying in the direction of travel Hood only adapted to the hood and the other body parts with considerable effort can be.

The invention is based on the object, both of the mentioned auxiliary devices for maintenance in particular to make easily accessible as well as to create a hood assembly that is compatible with the Fabrication and assembly of the hood cover is particularly advantageous.

The invention consists in that the space receiving the auxiliary equipment from above in known way by means of an additional, separate from the actual trunk or engine compartment hood, is covered releasably or hingedly arranged lid, which on the one hand with a Gap on the windshield and on the other hand with an angle or a step on the actual Engine or trunk lid connects and is arranged higher than the engine or in front of it Trunk lid.

Such a cover can easily be designed in this way be that he completely opens the upper opening of the room to accommodate auxiliary equipment releases and the work required for the maintenance of the auxiliary equipment housed therein not disabled. It is also advantageous that the hood arrangement for motor vehicles

the actual trunk or bonnet can be made shorter than before. Consequently the joints and compensating springs for these hoods and covers can also be made weaker

be ao. It is of particular advantage, however, that smaller hoods only twist to a small extent are subject and a more favorable sheet metal scrap results in their production. Finally, the adaptation of the cover to the adjacent trim parts is significantly simplified. In addition, the gaps can be used for air routing. It is particularly useful to if there is an air inlet gap between the lid and the hood. This results in a special one favorable sheet metal waste if the facing edges of the lid and the hood in the Viewed in plan, they are designed in a straight line.

In a further embodiment of the invention, the cover and the hood can advantageously be shared Axis can be arranged so that it can be opened. For the lid and the hood are then appropriate common bearing blocks provided and the articulated arms of the hood outside and the articulated arms of the Cover arranged within the bearing blocks, or vice versa. Especially when the auxiliary device The receiving space contains heat exchangers and which are used to heat the passenger compartment Air is passed through this heat exchanger, it is useful if the suitcase or Engine compartment, in particular the engine compartment, through the hood and / or that accommodating the auxiliary devices Space are sealed by the lid so that no air in the trunk or engine compartment the space for the auxiliary equipment can enter in order to avoid contamination of the supplied to the passenger compartment Avoid air with oil and gasoline fumes.

The invention is described below with reference to the exemplary embodiments shown in the drawing described and explained in more detail. It shows

F i g. 1 is a perspective view of the body of a passenger car with a hood arrangement according to the invention in a schematic representation,

F i g. 2 and 3 schematic longitudinal sections through the front part of the body according to FIG. 1,

4 shows the side view of a bearing arrangement common to the hood and cover

F i g. 5 shows the perspective view of the individual parts of a bearing arrangement similar to FIG. 4th

The body of the passenger car according to FIG. 1 is in its front part with a hood 1 provided, to which a higher arranged additional cover 2 connects to the rear. The one another facing edges of the cover 1 and the hood 2 are formed in a straight line when viewed in plan.

As can be seen in more detail from FIGS. 2 and 3, the cover 2 closes a space 3 from above, which is arranged between the trunk or engine compartment 4 and the bulkhead 5 of the vehicle and for It is used to accommodate auxiliary equipment of the vehicle. In the F i g. 2 and 3 is just the steering gear 6, however, heat exchangers, windshield wiper motors, for example, can also be used in space 3 and the like. Be arranged.

In the illustrated embodiment, the cover 2 can be opened about the axis 7, which also at the same time represents the pivot axis for the hood 1. The hood 1 and the cover 2 are shown in FIG. 3 in opened State shown. The F i g. 3 it can be seen that both the auxiliary equipment receiving space 3 and the trunk or engine compartment 4 are easily accessible from the outside.

The joint pieces connecting the cover 2 and the hood 1 to the axis 7 are designed so that the higher-lying lid 2 overlaps the hood 1 somewhat, so that between the lid and the hood an air inlet gap remains open. Another gap is also between the rear edge of the Lid 2 and the windshield 8. The through the gap of the lid 2 and hood 1 into the room Incoming air can then, as indicated by the arrows 9, be guided along the outside of the windshield 8, but also optionally after passing through a heat exchanger around the lower edge the windshield around along the inner surface of that windshield into the passenger compartment 10 are initiated, as indicated by the arrows 9 '. That by the mentioned column in the Rainwater entering space 3, on the other hand, can flow off through openings 11, which are in the area of the deepest point of the room 3 are attached. The path of rainwater is through the dotted Lines 12 indicated.

While the gap between the cover 2 and the hood 1 or the windshield 8 because of of the stepped or angular transition between these components are present, preferably It is deliberately not sealed, but used for air ducting and also for water drainage expedient to seal off the space 4 at least when it serves as an engine compartment in order to cross over of oil or gasoline vapors from room 4 into room 3 and from there into the passenger compartment 10 to avoid. For this purpose, in the illustrated embodiment, the walls of the Space 4 is provided at the top with a flange 13 on which the hood is optionally interposed from sealing strips to cherish flat, as it is the F i g. 2 shows in more detail.

In order to store the hood 1 and the cover 2, both of which are pivotable about the same axis 7, the cover 2 partially overlapping the hood 1 to form a gap, the arrangement according to FIG. 4 find use. There, a bearing block 16 is attached to the supporting structure part 14 by means of the screws 15, to which the hood 1 is articulated by means of the angle arm 21 and the cover 2 is articulated by means of the angle arm 22. The two angle arms each have flanges 21 'and 22' for fastening the hood or cover. As shown in Figs. 2 to 4 indicated, spray nozzles 17 of a windshield washer system can also be attached to the cover 2 together with the angle arms 22. The hood 1 and the cover 2 are shown in FIG. 4 also in the opened position V and 2 'with dashed lines.

The formation of the angle arms 21 with the flanges 21 ′ for the hood 1 and the angle arms 22 with the flanges 22 'for the cover 2, the perspective view decreases particularly clearly F i g. 5 recognize. There are only instead of the bearing blocks 16 according to FIG. 4 angle bands 16 'shown, the holes 18 at the end of its vertical leg for screwing to structural parts of the vehicle and at the end of their horizontal leg have rolled-up eyes 19 for receiving hinge pins, which then form the pivot axis for the hood and the lid. The angle lever 21 of the Hood 1 are arranged at such a distance that they come to lie outside the bearing bracket 16 ', while the angle lever 22 for the smaller cover 2 engage between the bearing bracket.

The invention is not limited to the illustrated embodiments limited. In particular, the cover can continue or also the surface of the hood be arranged lower than the hood. Furthermore, the lid does not need to be hinged, but can instead be releasably held on the vehicle body in some other way.
