Patent number: 10215085Abstract: In a two-stage supercharging electric-assist turbocharger, a first compressor wheel, a rotor of an electric motor, a second compressor wheel, and a turbine wheel are coaxially coupled to a same, common shaft member, in that order. A compressor housing is structured to define therein a communicating passage to accommodate the electric motor in the communicating passage. A first water jacket is formed in at least one rib integrally formed with an outer periphery of a motor housing and also serving as a radiating fin, for forced-cooling air flowing through the communicating passage. A second water jacket is formed in a motor housing for forced-cooling a stator of the electric motor. A third water jacket is formed in an intermediate housing constructing a part of the compressor housing for forced-cooling a control unit configured to control the electric motor.Type: GrantFiled: April 20, 2017Date of Patent: February 26, 2019Assignee: MAHLE FILTER SYSTEMS JAPAN CORPORATIONInventors: Takahisa Yamashita, Vijayakumar Sivaraman, Haruo Iwano

Publication number: 20100000811Abstract: A geared motor 10G, which is provided with an electric motor 10 and a reduction gear mechanism 11 for reducing the rotation speed thereof and transmitting the reduced speed to a wheel 2, is elastically connected to a knuckle 5 by a dynamic vibration absorber 20 which comprises a motor mounting member 21 attached to a lateral side of a motor case 10a, a knuckle mounting member 22?? attached to the knuckle 5, a spring member 23 interconnecting the motor mounting member 21 and the knuckle mounting member 22??, two guide members 24,24 for guiding the operation of the spring member 23 in the up-and-down direction, and a damper 25?? disposed in parallel with the guide members 24,24. Also, the electric motor 10 and the dynamic vibration absorber 20 are disposed posterior to the reduction gear mechanism 11. As a result, the geared motor 10G is provided with an ample stroke width, and also the dynamic vibration absorber 20 can perform its expected function fully.Type: ApplicationFiled: January 23, 2007Publication date: January 7, 2010Applicant: KABUSHIKI KAISHA BRIDGESTONEInventor: Haruo Iwano

Publication number: 20090133944Abstract: An electric motor 10 and a reduction gear mechanism 11 are connected to each other by a flexible coupling 12, such as an Oldham's coupling, which is a power transmission mechanism. Also, a casing 11c of the reduction gear mechanism 11 is integrally structured together with a knuckle 5, which is an unsprung part of a vehicle, or mounted to the knuckle 5. Further, a motor case 10a of the electric motor 10 is mounted to a motor mounting member 4m provided on the lower part of a strut 4 for suspending the knuckle 5 through the medium of a shock absorbing mechanism 20 equipped with a spring member 21, a damper, and two guide members 23 for guiding the operating direction of the spring member 21 and the damper. An in-wheel motor system thus structured allows the mass of the motor 10 to act as the mass of a dynamic damper and thus features not only improved ground contact performance and riding comfort of a vehicle running on a rough road but also superior space efficiency.Type: ApplicationFiled: December 11, 2006Publication date: May 28, 2009Applicants: Kabushiki Kaisha Bridgestone Technical Center, Kabushiki Kaisha BridgestoneInventors: Satoshi Nishioka, Haruo Iwano, Katsumi Tashiro
