POWER TRANSMISSION DEVICE FOR VEHICLE

摘要

A power transmission device (21) for a vehicle is equipped with: a casing (22) mounted on the vehicle (1); a rotary shaft (35) supported within the casing (22) and rotated by an engine (10); first and second transmission shafts (40), (41) that are supported within the casing (22) and change the rotational speed of the rotary shaft (35); a clutch mechanism (50) for a first speed and a clutch mechanism (51) for a second speed, provided between the rotary shaft (35) and the first and second transmission shafts (40), (41), respectively; and an output shaft (54) that outputs the rotation of the one transmission shaft selected by clutch mechanism (50) or (51). A first brake device (61) that applies braking force to the first transmission shaft (40) and a second brake device (71) that applies braking force to the second transmission shaft (41) are provided on the casing (22).
