AI Technical Summary

Problems solved by technology

Such hydraulic pumps are necessarily accompanied by energy losses
The disadvantage of motor-driven clutches is their size, due to the increased axial length due to the clutch plates, shift forks and bearings
This is problematic for meeting vehicle packaging requirements in the case of P1 / P3 dual motor transmissions

Embodiment Construction

[0046] will refer to Figure 1 to Figure 5A first embodiment of a hybrid powertrain, or simply the drivetrain 10, is described. As those skilled in the art will recognize, this is a P1 / P3 dual motor hybrid configuration. Thus, the system 10 includes an internal combustion engine 12, a first rotating electrical machine 14, and a second rotating electrical machine 16, which may be referred to as EMs. Both EM 14 and EM 16 include stators 14.1, 16.1 and rotors 14.2, 16.2 and can operate as motors or generators. The driveline 10 also includes a first clutch arrangement 18 and a transmission 20 having a plurality of gears connected to a differential 22 having a pair of drive shafts 24 (half shafts) for connection to wheels (not shown). axis).

[0047] The first EM 14 is arranged on the engine 12 side to rotate together with the engine crankshaft 26 . Here, the first EM 14 is actually mounted with its rotor 14 . 2 fixed to the flywheel 28 attached to the crankshaft 26 , ie the EM...

Abstract

A clutch device for a hybrid vehicle driveline includes: an input shaft (30) connected to a crankshaft (26) of an internal combustion engine (12); an output shaft (32) for connection to a transmission (20); a one-way clutch (50) including an outer race (54) and an inner race (52) connected to rotate together with the input shaft (30); a coupling hub (58) rotationally coupled with the output shaft (32); and a synchronizer ring (60) arranged between the coupling hub (58) and the one-way clutch (50), the synchronizer ring cooperating with an outer race of the one-way clutch. The coupling sleeve unit (62) is selectively and axially movable across the coupling hub (58), the synchronizer ring (60), and the outer race (54) among: a neutral position; a first position in which the coupling sleeve unit rotatably couples the coupling hub, the synchronizer ring, and the outer race; and a second position in which the coupling sleeve unit rotatably couples the coupling hub, the sync ring, the outer race, and the inner race. A drive train comprising such a clutch device is also proposed.

Description

technical field [0001] The present invention generally relates to the field of motor vehicles. More particularly, the present invention relates to hybrid vehicles, and in particular to clutch arrangements and drive trains for hybrid vehicles. Background technique [0002] due to CO 2 Tighter regulations on emissions and due to environmental awareness, hybrid and fully electric vehicles are becoming more and more popular. [0003] In this case, the P1 / P3 dual-motor hybrid structure has gained attention. The traditional P1 / P3 structure includes an internal combustion engine and two rotating electric machines. The first electric machine is directly connected to the engine crankshaft. A clutch is provided to decouple the engine from the transmission. The clutch has an input shaft connected to the engine crankshaft and an output shaft that transmits torque to drive wheels via a transmission. The second electric machine is coupled to the clutch output shaft. [0004] This h...
