Definitions
- the present invention relates to an oil tank for the motor vehicle engine unit.
- the engine groups of vehicles automobiles include a main housing open down and a bowl fixed on the lower peripheral edge of the main casing and which constitutes a reserve for the lubricating oil of the engine group, a pump for circulating the lubricating oil from of this reserve through the engine group organs.
- the purpose of the present invention is to provide a solution radically different.
- the invention relates to a lubricating oil tank for the engine group arranged in an engine compartment, opened by below, of a motor vehicle, which includes a tarpaulin flat which is arranged in the lower part of said compartment, in below said motor group, and which is connected to said motor group of a partly by at least one oil outlet pipe and partly by at less an oil inlet pipe connected to the oil pump of said group motor.
- said cover extends approximately over the entire surface of the lower part of said compartment.
- said tarpaulin can advantageously include a lower part connected to said oil inlet pipe.
- said outlet conduit is preferably connected to the lower part of a bowl of said motor group.
- said tarpaulin is preferably arranged at less partly in the air flow delivered by the fan of said motor group and the air flow under the vehicle.
- the wall of said cover comprises preferably projecting outer and / or inner ribs.
- said conduits are preferably deformable.
- said tarpaulin can advantageously be fixed, at least partially, to the structure of said vehicle.
- the means for fixing said sheet to the structure of said vehicle are preferably deformable.
- said tarpaulin can advantageously be fixed, at least partially, to said power unit.
- the means for fixing said cover to said motor group are preferably deformable.
- the solution proposed by the invention allows in particular to use gravity to bring the lubricating oil from the crankcase up the tarp, improve the cooling of the oil lubrication, to use the tarpaulin as a means of masking the noise of the group motor.
- a motor unit 1 of a motor vehicle all of which equipment is carried by a casing 2 and at the front of which is provided a fan group 3.
- the engine group 1 is arranged in a compartment 4 of the vehicle whose structure or body includes two side members 5 which extend on either side and at a distance from the power unit 1.
- the engine group 1 is fitted with a low oil tank 6 thickness and large opposite main surfaces, including the walls are for example sheet metal.
- This cover 6 has a part 7 which extends substantially horizontally below and away from the power unit 1, as well as longitudinal sides 8 which extend upwards so that the sheet 6, in cross section, is substantially under the shape of a U whose bottom is formed by part 7 and whose branches 8 move apart, the upper edges of the flanks 8 extending just below the side rails 5.
- part 7 of the sheet 6 has a front part 7a which is situated at a level lower than its part rear 7b, these parts 7a and 7b being connected by an intermediate part 7c tilted forward.
- the cover 6 is suspended from the vehicle body by means of connecting strips 9 which connect the upper edges of its sides 8 to lower parts of the side members 5, these bands 9 incorporating preferably a material that is deformable so as to absorb vibrations and dimensional variations.
- the upper rear part 7b of the cover 8 is connected to a bowl dry bottom 10 of the motor unit 1 thanks to an outlet duct 11, the bowl 10 being arranged so as to collect the oil from lubrication circulating in the engine group 1.
- the lower part 7a of the cover 6 is connected to the entry of a oil pump 12 of the engine group 1 via a conduit input 13.
- the conduits 11 and 13 are at least partly in a material which can be deformed so that it can absorb vibrations and dimensional variations.
- Pump 12 of engine group 1 sucks in lubricating oil to the lowest part 7a of the sheet 6 through the conduit 13, the oil descending by gravity into the cover 6 of its rear upper part towards its lower front part.
- the cover 6 constitutes a reservoir of lubricating oil outside the power unit 1.
- the cover 6 for lubricating oil is in the air flow circulating in the lower part of compartment 4 of the vehicle, below the engine group 1. It is also located in the air flow generated by the fan unit 3 and the circulating air under the vehicle.
- the walls of the tarpaulin 6 have external ribs 14 and ribs interior 15 shown schematically in FIG. 2 and carried out in a conventional manner.
- the cover 6 for lubricating oil extending almost over the entire surface of the lower part of compartment 4 of the vehicle, it contributes to the masking of the noise generated by the power unit 1 placed in this compartment, its surface can advantageously be coated with sound absorbers
- the motor unit 1 no longer comprising a tank large internal oil, the lower part of its casing 2 can advantageously be reduced and contribute to the strengthening and engine stiffness.
