Patent number: 8066605Abstract: A planetary transmission includes a sun gear, which constitutes an input drive to the planetary transmission, a ring gear arranged around the sun gear, and a planet carrier which is designed to rotate and which carries at least one planet wheel, which planet wheel meshes with the sun gear and the ring gear. The planet carrier constitutes an output drive from the planetary transmission. The planetary transmission further includes a wet disk brake, a first set of brake disks in the brake being rotationally locked to the planet carrier and thereby in operation rotating at the rotational speed of the planet carrier. The planetary transmission further comprises an arrangement for circulation of a cooling fluid through the brake which is rotationally locked to the sun gear and thereby in operation rotates at the rotational speed of the sun gear.Type: GrantFiled: July 1, 2005Date of Patent: November 29, 2011Assignee: Volvo Construction Equipment ABInventors: Tim Kingston, Mats Åkerblom

Patent number: 7399252Abstract: The invention relates to an arrangement for driving a wheel of a vehicle comprising a planetary gear set, which in turn comprises a planet carrier. At least one surface of the planet carrier has a toothed structure and extends in such a way that the toothed structure is exposed in the axial direction of the planet carrier. The arrangement comprises a power transmission part and at least one surface of the power transmission part has a toothed structure that corresponds to the toothed structure of the planet carrier surface and an extent that corresponds to the extent of the planet carrier surface. The toothed structures of the planet carrier and the power transmission part intermesh with one another. The invention also relates to the planet carrier per se.Type: GrantFiled: March 8, 2006Date of Patent: July 15, 2008Assignee: Volvo Construction Equipment Holding Sweden A BInventor: Tim Kingston
