摘要： An apparatus for controlling temperature of fluid in a differential assembly. The apparatus includes a differential housing having a number of sidewalls which collectively define an internal component chamber, wherein (i) the internal component chamber has a differential sump located therein, and (ii) the differential sump has a sump input port defined therein. The apparatus also includes a first operational pressure source which advances fluid from the internal component chamber of the differential housing. The apparatus further includes a diverter valve which receives fluid advanced by the first operational pressure source from the internal component chamber. The diverter valve has a cold fluid output port and a hot fluid output port. A heating fluid return line is interposed between the cold fluid output port of the diverter valve and the sump input port of the differential sump. A cooling fluid return line is interposed between the hot fluid output port of the diverter valve and the housing input port of the differential housing. The diverter valve is selectively operable between (i) a heating position in which fluid advanced by the first operational fluid source is diverted to the differential sump of the differential housing via the heating fluid return line and (ii) a cooling position in which fluid advanced by the first operational fluid source is diverted to contact the number of sidewalls of the differential housing via the cooling fluid return line. A method of controlling temperature of fluid in a differential housing is also presented.

摘要： This invention relates to a method and apparatus for maintaining equal air pressure in a pair of tires on a work machine. The invention provides a valve body with a pair of piston chambers. A piston is reciprocatably positioned within each piston chamber, the pistons are biased toward a first closed end of the piston chambers. The closed end of each piston chamber is connected by a passageway to one of the tires. Each piston chamber is additionally fluidly connected to the other piston chamber. When the air pressure in each tire is above a predetermined amount the pistons are moved away from the closed end of the piston chamber and airflow is permitted between the piston chambers thereby balancing the tire pressures. If the pressure in either tire is below the predetermined minimum, the piston in that respective piston chamber moves toward the first end to block, airflow between the piston chambers.

摘要： A steering apparatus for a zero-turn radius vehicle using a steering mechanism coupled to a first set of wheel assemblies by a plurality of cables. User input to the steering mechanism causes the cables to turn the first set of wheel assemblies about a vertical axis. Specifically, the cables link the steering mechanism to cam mechanisms that are attached to each wheel assembly. The design of the cam mechanism, which preferably includes two cams of varying radii, enables the two wheel assemblies to rotate about their vertical axes at varied degrees of rotation and greater than ninety degrees from the forward facing position, thereby resulting in zero-turn radius capability.

摘要： An apparatus for controlling temperature of fluid in a rear axle assembly includes a rear axle housing having an internal component chamber. The internal component chamber has a rear axle sump located therein. The apparatus also includes a temperature control operational pressure source coupled to the internal component chamber. The apparatus further includes a diverter valve coupled to the temperature control operational pressure source. The apparatus includes a heating fluid return line interposed between the diverter valve and the rear axle sump, and includes a cooling fluid return line interposed between the diverter valve and the rear axle housing. The temperature control operational pressure source is selectively operable between (i) a first rate mode in which it advances fluid from the internal component chamber at a first flow rate, and (ii) a second rate mode in which it advances fluid from the internal component chamber at a second flow rate. The diverter valve is selectively operable between (i) a heating position in which fluid advanced by the temperature control operational pressure source is diverted to the rear axle sump via the heating fluid return line, and (ii) a cooling position in which fluid advanced by the temperature control operational pressure source is diverted to the rear axle housing via the cooling fluid return line. A method of controlling temperature of fluid in a rear axle housing is also presented.

摘要： A mechanical differential assembly having an increased bearing load zone capacity. The mechanical gear assembly maintains a proper load capacity of rollers of the bearings which support a differential gear assembly. The mechanical differential assembly thus maintains alignment of the inner and outer races of the bearings regardless of an axial force placed on the bearings, any loads placed on the differential gear assembly or the like during driving condition. The mechanical differential assembly includes a differential gear assembly supported on a first end by a cylindrical bearing and supported on the second end by a pair of tapered bearings.
