475161000 | WITH TRANSMISSION COOLING OR HEATING MEANS | 10 |
20080268998 | Planet Transmission, Drive Device Comprising the Planet Transmission and Vehicle Comprising the Drive Device - 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. | 10-30-2008 |
20080312023 | VEHICLE DRIVELINE COMPONENT HAVING HEAT SINK FOR INCREASED HEAT REJECTION CAPABILITIES - An axle assembly that includes an axle housing assembly, a differential disposed in the axle housing assembly, an input pinion, a pair of axle shafts and a heat sink. The input pinion is coupled to the axle housing assembly and is configured to transmit a rotary input to the differential. The axle shafts are coupled to the differential and housed in the axle housing assembly. The heat sink is coupled to the axle housing assembly and is formed of a material having a thermal conductivity that is greater than that of the axle housing assembly. The heat sink does not consist entirely of a chrome plating, a zinc plating or a cadmium plating. A cover for an axle assembly is also provided. | 12-18-2008 |
20090253546 | Integrated Motor Cooling/Clutch Backfill System For Use In A Hybrid Transmission - A fluid is supplied to a housing of a hybrid transmission. An overall system line pressure is elevated to induce leakage of the fluid through a control system. The leaked fluid is flowed through at least one backfill passage to the housing of the hybrid transmission. The leaked fluid is flowed over the motors disposed within the housing to cool the motors. The fluid that is flowed over the motors is collected to create a head pressure within the housing. The head pressure forces the collected fluid upwards within the transmission housing and into clutches that are disposed therein. | 10-08-2009 |
20100062890 | FLUID SUPPLY APPARATUS - A fluid supply apparatus includes a main passage through which fluid flows, a parallel passage section, and a pressure loss adjusting mechanism. The parallel passage section includes a plurality of passages connected in parallel to the main passage. The parallel passage section includes a selector valve, which changes the number of passages through which fluid passes among the plurality of passages. The pressure loss adjusting mechanism suppresses change in the pressure loss at the parallel passage section associated with change in an operating state of the selector valve. | 03-11-2010 |
20100197441 | METHODS AND SYSTEMS FOR HEATING TRANSMISSION FLUID - Systems and methods are provided for heating transmission fluid in a vehicle, the vehicle comprising an engine and a transmission, the engine including a heat exchanger. One example method comprises, during a first engine running condition, operating an auxiliary transmission fluid pump to generate pressure in the transmission fluid and pump transmission fluid to the heat exchanger, and during a second condition where the engine is not running, operating the auxiliary transmission fluid pump to generate pressure in the transmission fluid and pump transmission fluid to the heat exchanger. | 08-05-2010 |
20100234160 | DIFFERENTIAL GEAR DEVICE - A differential gear device includes a case that rotates around a rotation center line; a first protruding portion protruding from an inner surface of the case toward the rotation center line; a rotatable first gear provided around the first protruding portion; and a second gear including a ring-shaped base portion, and a connection portion formed on an inner peripheral surface of the base portion, and connected to an output shaft, wherein the second gear engages with the first gear. One end of the base portion, which is located in the case at a position inside an opposite end of the base portion in an axial direction of the output shaft, is located in a region that is located directly ahead of the first protruding portion in a direction in which the first protruding portion protrudes. | 09-16-2010 |
20110077117 | Eccentric Oscillating Type Speed Reducer - The present invention provides an eccentric oscillating type speed reducer that can more effectively be cooled with an extremely simple structure. | 03-31-2011 |
20110082001 | VEHICLE DRIVELINE COMPONENT HAVING HEAT SINK FOR INCREASED HEAT REJECTION CAPABILITIES - An axle assembly that includes an axle housing assembly, a differential disposed in the axle housing assembly, an input pinion, a pair of axle shafts and a heat sink. The input pinion is coupled to the axle housing assembly and is configured to transmit a rotary input to the differential. The axle shafts are coupled to the differential and housed in the axle housing assembly. The heat sink is coupled to the axle housing assembly and is formed of a material having a thermal conductivity that is greater than that of the axle housing assembly. The heat sink does not consist entirely of a chrome plating, a zinc plating or a cadmium plating. | 04-07-2011 |
20140135163 | DEVICE AND METHOD FOR COOLING AN AXLE DIFFERENTIAL OF A MOTOR VEHICLE - A device and method for cooling an axle differential of a motor vehicle includes an air-guiding plate for guiding the air stream under the motor vehicle. An air-guiding plate is provided for guiding the air stream under the motor vehicle. | 05-15-2014 |
