Embodiment Construction

[0049] figure 1 and 6 An automatic transmission for a thermal / electric hybrid vehicle is schematically shown with:

[0050] – input shaft AE driven by heat engine,

[0051] – output wheel, output ring gear or output gear RCPS,

[0052] - fastening elements ES, such as housings,

[0053] - a motor ME, the stator ST of which is fixed to the fixture ES,

[0054] - first, second, third, fourth and fifth selective torque-transmitting mechanisms C124, C345, C1, C23, C5 which are selectively engageable or actuatable in order to establish, on the one hand, At least three speed ratios for driving the vehicle under the action of running, on the other hand at least five speed ratios are established for driving the vehicle under the action of the heat engine.

[0055] According to the invention, this transmission also has a single double planetary gear set TPR of the Lavigny Jooh type, which comprises the following components as constituent functional elements: first and second sun g...

Abstract

The subject of the present invention is an automatic transmission for a hybrid vehicle, the automatic transmission comprising an input shaft (AE) driven by the combustion engine, an output gearwheel, ring gear or pinion (RCPS), a stationary element (ES) such as a casing for example, an electric machine (ME) of which the stator (ST) is secured to the stationary element (ES), first, second, third, fourth and fifth selective torque transmitting members (C124; C345; C1; C23; C5) that can be selectively engaged or activated in order to establish different transmission ratios, a single double planetary gearset of the Ravigneaux type (TPR) the constituent functional elements of which are arranged as two sets of planetary gears (ET1 and ET2) connected by the aforementioned members to the input shaft (AE) and to the stationary element (ES), the rotor (RO) of the electric machine (ME) being mounted on a functional element (RI) that injects the movement of the gearset (TPR).
