Title:
HYBRID VEHICLES WITH ONE-WAY CLUTCH AND AUXILIARY LOADS DRIVEN BY THE MOTOR AND/OR THE ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/079238
Kind Code:
A3
Abstract:
The invention relates to the field of hybrid vehicle propulsion systems, where there is more than one source of on-board rotary motion. A hybrid vehicle comprises a battery (10) for powering means for driving the vehicle, a motor/generator (40) having a motor/generator shaft (45), and an engine (50) having an output shaft (55). The engine output shaft (55) is coupled to the motor/generator shaft (45) by a one-way clutch (70). The one-way clutch (70) is arranged to allow the motor/generator (40) to rotate faster than the engine output shaft (55), and does not allow the engine output shaft (55) to rotate faster than the motor/generator shaft (45). The one-way clutch (70) is arranged to never transmit torque from the motor/generator shaft (45) to the engine shaft (55), and to transmit torque from the engine output shaft (55) to motor/generator (40) output when the clutch (70) locks the engine output shaft (55) and the motor/generator shaft (45) together to rotate to the same speed. The hybrid vehicle comprises one or more auxiliary loads (60), the one or more auxiliary load(s) (60) being connected directly to the motor/generator output shaft (45) so that the one or more auxiliary loads (60) are driven whenever the motor/generator shaft (45) rotates. The auxiliary load(s) (60) is/are driven by motor/generator (40) alone when the motor/generator (40) functions as a motor and rotates the motor/generator shaft (45) faster than the engine output shaft (55). The auxiliary load(s) (60) is/are driven by the engine (50) when torque is transmitted via the one way clutch (70) from the engine output shaft (55) to the motor/generator (40).
