Abstract

PURPOSE:To prevent the deterioration of grease and to extend its life by providing cooling exhaust ports along a rotation axis to the side plate of a rotary electric machine positioned to the side of a brake disc and spraying cooling fluid of the rotary machine on the rotation axis. CONSTITUTION:A brake disc 28 is loaded on the axis to a rotation axis 24 of a rotary electric machine 20, a cooling exhaust port 30 is provided along the rotation axis 24 to the side plate 21a of the rotary electric machine 20 positioned to the side of the brake disc 28, and the cooling fluid of the rotary electric machine 20 is sprayed to the rotation axis 24 from the cooling exhaust port 30. Accordingly, at the time of driving of the rotary electric machine 20, part of the cooling fluid produced by the rotation of a rotor 24a is exhausted from each of exhaust ports 21b. The rest of cooling fluid at the time of braking is ejected in the direction of the axis of the rotation shaft 24 from each of cooling exhaust ports 30 to cool the conduction heat of the rotation axis 24, and at the same time, even if the abraded powder produced at the time of braking is scattered to the side of a bearing 23, the adherence of the powder can be prevented.
