Embodiment Construction

[0025] exist figure 1 In this case, the power transmission system comprises in particular a heat engine 10 of an internal combustion engine with an engine shaft 12 here emerging from the engine crankshaft, the power transmission system also comprises a variable speed transmission 14 and an engine axle 16, the engine axle 16 The drive wheels 18 of the vehicle can conveniently be driven through a differential axle 20 .

[0026] The motor shaft 12 also has the function of a driven shaft, but for reasons of simplification of the detailed description, this shaft will be named motor shaft to distinguish it from the other shafts of the transmission.

[0027] When the power transmission system is applied to a hybrid vehicle, the drive / slave mechanism 22 is associated with the power transmission system.

[0028] In the following embodiments, the master / slave mechanism is an electric motor, either as an electric motor driving the wheels or as a slave mechanism generating a current sour...

Abstract

The present invention relates to a power train of a motor vehicle comprising a heat engine (10) having a shaft (12), a variable-speed transmission device (14) including a planetary gearset of the engine (24) having a planet gear (34) and a sun gear (46) each connected to the shaft (12) of the heat engine (10) by controlled-operation coupling (26, 28) and to a stationary portion (44) of the vehicle by a one-way automatic coupling (30, 32), and a gear carrier (54) connected to an axle (16) by a transmission path (96, 98). The power train includes a one-way automatic coupling (64) linking the gear carrier (54) to said transmission path.

Description

technical field [0001] The present invention relates to a powertrain for driving a motor vehicle, and more particularly to a powertrain for a hybrid vehicle. Background technique [0002] As is known, a vehicle of this type includes a powertrain, such as a traction / propulsion drive mode, using a heat engine with a transmission, usually an internal combustion engine, alone or in combination, and a drive / slave mechanism type, a master / slave mechanism such as a rotating electrical machine connected to a power source, such as one or more accumulators or batteries. [0003] This combination optimizes vehicle performance, as well as reduces levels of air pollutant emissions and fuel consumption. [0004] Therefore, when it is desired to drive the vehicle with a large torque over a wide speed range and limit the generation of exhaust gas and noise, such as in a city, it is preferable to drive the vehicle with an electric motor. [0005] Conversely, when high driving force and lon...
