Patent number: 9017205Abstract: A transmission unit comprises a planetary wheel set, which comprises a plurality of gearwheel elements and is designed as a pump which effects delivery of hydraulic fluid from a suction zone to a pressure zone of a pump casing containing the planetary wheel set by means of the gearwheel elements. A controllable throttling device is provided in order to selectively throttle a fluid flow pumped between the suction zone and the pressure zone and thereby to brake the gearwheel elements of the planetary wheel set relative to one another. A fluid reservoir, which can be connected simultaneously to the suction zone and to the pressure zone via the throttling device, is arranged in a pump casing interspace formed between a plurality of gearwheel elements of the planetary wheel set.Type: GrantFiled: December 15, 2011Date of Patent: April 28, 2015Assignee: MAGNA Powertrain AG & Co KGInventor: Herbert Steinwender

Patent number: 5478287Abstract: A drive mechanism, in particular for motor vehicles having a combustion engine including at least one compressor of the displacement type integrated by way of members of a planetary gear drive into the transmission train, and which by means of valves can be regulated infinitely variably and which on the suction side serves for cooling the installation and on the motor side for supplying charging air and on the power take-off side serves to increase the rate of rotation. The reaction force of the compressor is transmitted to the planetary wheels of a gear assembly driven with down gearing and there counteracts the deviation movement, i.e. the pivoting of the planetary gears when under load. A differential gear mechanism between the gear assembly on the one hand and the compressor respectively gear casing on the other hand including two planetary gear members connected to permit a gear ratio range from idling up to 1:1.Type: GrantFiled: April 19, 1993Date of Patent: December 26, 1995Inventor: Gunter Mehnert

Patent number: 4966264Abstract: A thrust washer has a protrusion which is formed with a projecting pawl. The rotating member is formed with a through hole, into which the protrusion of the thrust washer is inserted, such that the pawl is projected out on the opposed surface remote from the thrust washer of the rotating member, whereby the upstanding surface of the pawl is used as a stop means. Thus, the thrust washer is positively secured to the rotating member.Type: GrantFiled: January 4, 1989Date of Patent: October 30, 1990Assignee: Aisin Aw Co., Ltd.Inventors: Youichi Hayakawa, Chihiro Hosono, Masaaki Nishida, Kozo Kato
