Title:
VEHICLE POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/196318
Kind Code:
A1
Abstract:
Provided is a vehicle power transmission system that makes it possible to use a simple configuration to resolve the collision of dog teeth during shifting operation of a transmission while minimizing the fuel consumption amount and noise. A vehicle power transmission system (100) is provided with a clutch (210) and a transmission (240) of which operation is controlled by an ECU (300). The transmission (240) is provided with an index plate (247) that rotates together with a shift drum (245) that rearranges shifting gears. The index plate (247) is provided with valley sections (247a) that hold a shifting gear, ridge sections (247b) that are formed so as to protrude between each valley section (247a), and recessed standby sections (247c) that are provided to the tip sections of the ridge sections (247b). When the ECU (300) detects a collision of dog teeth, the roller (248a) of an index arm (248) is positioned in the recessed standby sections (247c), the transmission (240) is temporarily set into neutral, and connection of the dog clutch is subsequently attempted again.
