Embodiment Construction

[0025] refer to figure 1 , 1 denotes a device according to the invention comprising an internal combustion engine 2 (not shown) whose output shaft is mechanically connected to a drive shaft 3 on which a first rotor 4 of a first electric machine 5 is mounted. A hollow driven shaft 6 is inserted on the drive shaft 3 so as to be freely rotatable relative thereto. On the driven shaft 6 is mounted the second rotor 7 of the second electric machine 8 and the first gear 9 or pair of gears 9 and 10 which engage or respectively engage a corresponding gear 11 or the first pair mounted on the countershaft 13 Respective gears 11 and 12 of the two pairs of gears, a further gear 14 is mounted on the countershaft 13 to transmit the motion to the drive wheels of the vehicle.

[0026] The first shaft 3 and the hollow shaft 6 can be integrated by means of a friction clutch 15 which can be driven by means of a programmable, automatically controlled actuator or a pedal 17 controlled for engageme...

Abstract

A hybrid traction system for the traction of a vehicle comprises an internal combustion engine (2, 102) , at least a first electric machine (5, 105) and at least a second electric machine (8; 108) , first transmission means (3; 103, 104, 104b) suitable for being connected mechanically to said internal combustion engine and to at least one of said electric machines (5; 105) , second transmission means (6; 106) suitable for being connected mechanically to at least one of said electric machines (8; 108) and to the wheels of the vehicle; the system comprises furthermore connecting or restraining means (15; 21; 111) suitable for enabling mechanical power to be transmitted to the wheels of the vehicle only by the internal combustion engine (2; 102) through said first transmission means (3; 103,104, 104b) and said second transmission means (6; 106) .

Description

technical field [0001] The invention relates to a hybrid drive system of the thermoelectric type, ie a drive system in which the power used in the drive is supplied by at least a heat engine and / or at least an electric machine. Background technique [0002] In the prior art, two types of hybrid drive systems are known: series hybrid systems and parallel hybrid systems. [0003] In a series hybrid system, the internal combustion engine produces mechanical energy that is supplied to a generator that produces electrical energy that is partly stored in the battery and partly supplies the electric motor that provides the drive for the vehicle. In these systems, the energy required for the drive of the vehicle is thus generated by the heat engine, but the drive is provided by means of the electric motor. [0004] The presence of the electric motor during the deceleration and braking phases is such that, by operating said electric motor as a generator, part of the vehicle's kinet...
