摘要： A power transmission device of a work vehicle includes a motor control unit that controls first and second motors to keep the transmission speed ratio at a maximum value when a vehicle speed is greater than a second vehicle speed where the transmission speed ratio reaches the maximum value obtainable by the power transmission device, and less than a third vehicle speed where a rotation speed of the second motor reaches a predetermined limit value. A controller increases a rotation speed of an engine from a second rotation speed of the engine when the vehicle speed is greater than the second vehicle speed and less than a third vehicle speed, and increases the rotation speed of the engine from a third rotation speed of the engine when the vehicle speed is greater than the third vehicle speed.

摘要： An ice drill. The ice drill includes a power head, the power head configured to allow the user to control operation of the ice drill and an engine, the engine producing an output rotation at a crankshaft. The ice drill also includes a planetary transmission. The planetary transmission receives the output rotation from the crankshaft, changes the rotation speed by a specified ratio, and outputs the rotation at an output shaft, wherein the output rotation is left-handed in orientation. The ice drill further includes an auger, the auger attached to the output shaft and a cutting blade, the cutting blade configured to be moved by the auger to create a hole in ice.

摘要： A drive module that includes an electric motor, a differential assembly with a differential input member and a pair of differential output members, a multi-speed transmission assembly, which transmits rotary power between the electric motor and the differential input member, and a pair of axle shafts that are each coupled to an associated one of the differential output members for rotation therewith. The multi-speed transmission assembly and includes a housing, a two-speed planetary transmission stage, a plurality of clutches and a transmission output member that provides rotary power to the differential input member. The two-speed planetary transmission stage has an input sun gear, which is driven by the motor, and employs a set of planet gears having compound planet gears that provide a gear reduction between the sun gear and the transmission output member. The clutches are employed to control an overall reduction ratio.

摘要： The present invention provides a Suspended Wheel Reducer and a suspended wheel crossing-zero multilevel transmission, both of which comprise a front planetary gear train, a rear planetary gear train and a suspended wheel. With different design for the dimension of the gear wheels contained in the front planetary gear train, the rear planetary gear train and the suspended wheel, it's possible to achieve optional different reduction ratios. The Suspended Wheel Reducer and the suspended wheel crossing-zero multilevel transmission have simple configuration, higher reliability, thus overcoming the drawback in prior art, in which a transmission mechanism for multilevel gear shift mechanism is required to achieve greater reduction ratio, reducing its overall dimensions and cost.
