Abstract:
A drive device includes: an oil pump (80); a first rotation transfer member drivably coupled to the oil pump (80) and driven by at least one of an internal combustion engine (2) and a rotary electric machine (3); and a second rotation transfer member drivably coupled to wheels and driven by the rotary electric machine (3). One of the first rotation transfer member and the second rotation transfer member is a pinion (64). The other rotation transfer member is a carrier (60) that rotatably supports the pinion (64). The pinion (64) and the carrier (60) are rotated together with each other in the case where the oil pump (80) is driven by the rotary electric machine (3).
Abstract:
A dual-motor power system or a dual-motor hybrid power system for a vehicle comprises a first motor (1), a second motor (2), an intermediate shaft (13), a first gear set (7, 14) disposed between a first driving shaft (3) and the intermediate shaft (13). The first driving shaft (3) couples with the intermediate shaft (13) via the first gear set (7, 14). A second gear set (12, 15) is disposed between a second driving shaft (4) and the intermediate shaft (13). A single synchronizer (8) is disposed around the second driving shaft (4). The synchronizer (8) can be switched between a neutral position, a first-speed-ratio position, and a second-speed-ratio position. In the neutral position, the second driving shaft (4) is decoupled from the first (7, 14) and second (12, 15) gear sets. In the first-speed-ratio position, the synchronizer (8) couples the second driving shaft (4) with the intermediate shaft (13) via the first gear set (7, 14). In the second-speed-ratio position, the synchronizer (8) couples the second driving shaft (4) with the intermediate shaft (13) via the second gear set (12, 15).
Abstract:
Object To provide a hybrid vehicle driving device capable of executing electric power regeneration using only a rotational speed range where the electric power generation efficiency is high. Constitution In the hybrid vehicle driving device including an engine drive system transmitting a drive force of an engine (7) to a transmission (17) through a one-way clutch (14) and transmitting a drive force after shifting by the transmission (17) to a rear wheel (WR) and a motor drive system transmitting a drive force of a motor (15) to the rear wheel (WR), the drive force of the motor 15 of the motor drive system is joined to a point upstream the transmission (17) and downstream the one-way clutch (14) in the engine drive system. The transmission (17) is provided with a twin clutch (18) capable of shifting between neighboring shift gears by alternately switching the connection state of a clutch (CL1) on one side and a clutch (CL2) on the other side, and is automatically shifted so as to produce an optional rotational speed and motor torque at which the electric power generation efficiency becomes high at the time of regeneration control of the motor (15).

An engagement device 10 includes a piece 11 that is disposed rotatably about a rotating shaft 30 and rotates in conjunction the rotating shaft 30, a sleeve 12 that is disposed coaxially with the piece 11 and performs engagement with the piece 11 and release from the engagement with the piece 11 by shifting in an axial direction, a control unit (a motor generator MG, an actuator 15, a return spring 16, and an ECU 40) that controls the rotation of the piece 11 and the shifting of the sleeve 12 in the axial direction, and a one-way clutch 14 that is disposed on a power transmission path from the rotating shaft 30 to a base body 32 coupled to the sleeve 12 . The ECU 40 rotates the piece 11 in the idling direction of the one-way clutch 14 when performing engagement or release of the sleeve 12 with or from the piece 11. Consequently, durability of dog teeth 11a and 12a can be improved, and durability of the engagement device 10 can be improved.
