摘要:
The invention concerns a motor vehicle comprising a vacuum brake device (40) and an alternator-starter (31). The vehicle is configured to produce a vacuum in the braking device by bringing the heat engine (1) into operation, driven by the alternator-starter (31). This makes it possible to reduce the fuel consumption and to propose a vehicle without a vacuum pump dedicated to the braking device (40).

The invention relates to an electric circuit (CE) for a motor vehicle, comprising a first electric power storage element (1), a current generator (3) connected in parallel with the first electric power storage element (1) between a reference potential (M) and a first node (E) of the circuit (CE), a vehicle on-board network (RDB) comprising at least one electric power consumption member (8) mounted between a first node (S) of the circuit (CE) and the reference potential (M), a voltage regulator (5) mounted between the first node (E) and the second node (S), comprising an inlet terminal connected to the first node (E) and comprising an outlet terminal connected to the second node (S). The circuit is characterised in that the regulator comprises a by-pass switch (10) mounted in series between the first and second nodes (E and S) corresponding to the inlet (E) and outlet (S) terminals of the regulator (5), said by-pass switch including a switch (K) and a diode (D) mounted in parallel on the switch (K) and extending from the inlet terminal (E) to the outlet terminal (S) of the regulator (5). The circuit is also characterised in that the regulator (5) comprises a reversible DC-DC converter (11) mounted in series with a second electric power storage element (12), said converter being connected to the outlet terminal (S) of the regulator (5) and the second electric power storage element (12) being connected to the reference potential (M).

The invention relates to a compact hydraulic module (11) for providing driving power to a vehicle, including a casing (16) in which a first (14) and second (15) hydraulic engine, mounted opposite each other, are accommodated, one of the two engines being rotatably supported by the other, each engine including a valve plate (12), a cylinder (8), a plate (9), and axial pistons on knuckles (6, 7) which are arranged between the plate and the cylinder and which engage therewith. Said hydraulic engines convert the energy from a pressurized fluid into mechanical energy in the form of torque driving a differential, which is contained in the same housing and the output shafts (3) of which are coupled to the drive wheels of the vehicle. Said differential comprises an axial coupling member (1) which is capable of coupling the hydraulic engines together and which is configured so as to distribute the torque to the output shafts, wherein the differential is rotatably mounted inside the hydraulic engine, and the rotational axis (XX') of the hydraulic engine coincides with the rotational axis of the differential.

The hydraulic reservoir (1) is attached by a number of circumferential bands (5) to the body shell (3) of the vehicle. The device of the invention consists of a band support (10) rigidly connected to at least one circumferential band (5) and attached to the floor (3). This band support (10) has, on the one hand, a part referred to as the "hose attachment" part which is separated from the circumferential band (5) in order to allow the connecting hose (4) to be passed between said circumferential band (5) and the band support (10) and, on the other hand, a means for attaching the connection hose (4) to said hose attachment part of the band support (10). Motor vehicles. Attachment of motor vehicle hydraulic reservoir connection hoses.
摘要:
Planet carrier system for epicyclic gear train (37, 39, 42) of a vehicle, notably motor vehicle, transmission, comprising a planet carrier body (16) and planet carrier shafts (13) which are mounted on the body. Each of the planet carrier shafts (13) comprises firstly a planet support shaft portion (33), passing through an orifice (22) in the body and lying on a first side (16S) of the body and secondly a protrusion (35) for axially blocking said planet carrier shaft (13) relative to the body (16). A securing device (60) for each planet carrier shaft (13) keeps the protrusion (35) pressed firmly against the body (16) around the orifice (22) on the second side (16F) of the body.
