POWER TRANSMISSION UNIT FOR VEHICLE

摘要

A power transmission unit for a vehicle comprises: a motor arranged on an output side of an engine coaxially therewith in a housing adjacent to an outer face of the engine; an end cover arranged in the housing to cover an end portion of the motor to protect from the engine; a rotary shaft extending coaxially with the motor to be connected to an output shaft of the engine while penetrating through the end cover; and an engagement device disposed on an outer circumferential side of the rotary shaft between the motor and the engine to selectively restrict a rotation of the rotary shaft. A sub-cover to which the rotary shaft penetrates is attached to an end face of the end cover and a chamber is hermetically enclosed by the sub-cover, the end cover, and the rotary shaft. The engagement device is held in the housing.

1. A power transmission unit for a vehicle, comprising:
a motor that is arranged on an output side of an engine coaxially therewith in a housing adjacent to an outer face of the engine; an end cover that is arranged in the housing to cover an end portion of the motor to protect from the engine; a rotary shaft that extends coaxially with the motor to be connected to an output shaft of the engine while penetrating through the end cover; an engagement device that is disposed on an outer circumferential side of the rotary shaft between the motor and the engine to selectively restrict a rotation of the rotary shaft, a sub-cover which is attached to an end face of the end cover and to which the rotary shaft penetrates; and a chamber that is hermetically enclosed by the sub-cover, the end cover and the rotary shaft whose outer diameter is smaller than an inner diameter of a stator of the motor, wherein the engagement device is held in the housing.
