Definitions

• the present invention relates to a device for supporting and fixing an engine on the chassis of a vehicle, in particular a motor vehicle.
• the document FR 2 792 858 describes a process for producing, by molding, an internal combustion engine cylinder head making it possible to reduce certain machining operations, in particular tapping operations.
• a metal alloy is cast in a mold containing non-fusible cores respectively corresponding to the recessed parts of the cylinder head such as the oil chamber, the water chamber, the intake or exhaust ducts and the combustion chamber.
• the casting is inserted into a fastening element for holding an insert against the yoke, this fastener being carried by a support core defining at least partially an outer face of the yoke.
• the object of the present invention is to provide a device for supporting and fixing an engine on the chassis of a vehicle, in particular a motor vehicle, which allows a gain in volume in the engine , and which is economical compared to the existing means of support and attachment of an engine on a vehicle chassis.
• the present invention relates to a device for supporting and fixing an engine on the chassis of a vehicle, in particular a motor vehicle, the engine comprising a closed cylinder block by a cylinder head obtained by a molding process and said engine being fixed to the chassis of the vehicle by means of an intermediate support connected directly to the cylinder head.
• the intermediate support is "monobloc" with the breech and the assembly formed by the breech and the intermediate support integrated into the breech is obtained by a single molding operation, so that in this way, the interface between the yoke and the intermediate support is eliminated.
• the operation of simultaneous molding of the cylinder head and the intermediate support can advantageously be a molding operation according to the technique of the lost mold.
• the assembly formed by the yoke and the intermediate support integrated in the cylinder head has holes for the passage of fastening means for rigidly connecting said assembly to the chassis of the vehicle.
• Figure 2 shows schematically the device for supporting and fixing an internal combustion engine on the chassis of a vehicle, according to the principle of the present invention.
• FIG. 1 Referring to the drawing of Figure 1, there is shown the cylinder head, general reference 1, an internal combustion engine of a motor vehicle, for example.
• This yoke 1 is connected to the chassis of the vehicle, in a conventional manner and known per se, via an intermediate support 2 already mentioned previously, reported and screwed directly on the yoke 1 of the engine.
• the intermediate support 2 is not directly connected to the engine chassis, but is fixed on a "right engine support (SMOD)", also referred to as "engine support” in the following text, itself fixed rigidly and directly on the chassis of the vehicle.
• SOD right engine support
• the "monobloc" assembly resulting from the simultaneous molding of the yoke 1 and the intermediate support 2 is intended to be fixed on the engine support (not shown) rigidly connected to the chassis of the vehicle by means of connecting means, by screwing for example, cooperating with the through holes 4 provided in the support portion of the assembly 1, 2.
• the support and attachment device of the motor described above has many advantages, among which the following advantages:
• this device is economic by allowing to remove machining operations faces facing the cylinder head and support, holes, tapping , and also allowing to remove fixing screws and positioning and mounting operations,
