Embodiment Construction

[0018] In each figure is shown a vehicle powertrain 10 comprising a main drive engine 12, such as a heat engine, a gearbox 14, and a drive shaft 16, for example through a differential not shown. Connects to vehicle drive wheels not shown. The output shaft 18 of the drive motor is drivingly connected to the input shaft 20 of the gearbox 14 via a clutch 22 .

[0019] In the example shown, the gearbox 14 is a manual gearbox, which may or may not be a mechanical automatic gearbox. The manual transmission has an output shaft 24 aligned with the input shaft 20 and an intermediate shaft 26 arranged parallel to the input shaft 20 and the output shaft 24 . The intermediate shaft 26 and the input shaft 20 are drivingly connected by respective gear sets 28 , 30 . In this example, the input shaft and intermediate shaft have a fixed speed ratio. In some gearboxes equipped with a decoupler mechanism not shown, the two shafts 26, 20 may be connected by two sets of meshing gears, but only ...

Abstract

The invention relates to a drive arrangement for at least one auxiliary equipment of a vehicle, wherein the vehicle comprises a driveline (10) including a gearbox (14), wherein the drive arrangement (40) comprises a power split device (50, 72) having at least three input / output couplings (52, 54, 56), the speed of all said at least three separate couplings being interdependent but not being with a fixed ratio one to the other, and wherein: - a first coupling (52) is connected to the driveline (10), - a second coupling (54) is connected to an electric machine (58), and - a third coupling (56) is connected to said at least one auxiliary equipment (38), characterized in that: - the first coupling (52) is connected to the input shaft (20) of the gearbox ( 14).

Description

technical field [0001] The invention relates to a drive structure for a vehicle accessory. Background technique [0002] A vehicle, such as a car or a truck, includes a power train that typically includes at least one drive motor, which may be an electric motor or a heat engine, for driving the drive wheels of the vehicle. In most cases, the drive motor is connected to the drive wheels through a gearbox having at least one input shaft connected to the drive motor and at least one output shaft connected to the drive wheels of the vehicle. [0003] Vehicles also include various accessories. The first category of accessories can be formed by accessories directly associated with the function of driving the engine, for example in case the engine is a heat engine, they can be fuel pumps, oil pumps, fans and generators. The second category of accessories can be formed by accessories required for other main functions of the vehicle, such as a power steering pump, an air compressor...
