摘要： A MTD unit according to a present disclosure includes a bearing member that has an inner ring, a plurality of rolling elements and an outer ring and is capable of bearing a radial load and a unidirectional axial load, a retainer that has a retaining part retaining the rolling elements such that the rolling elements are rotatable around their own axes and rotates around an axis of the inner ring in accordance with an orbital motion of the rolling elements around the inner ring, and a case that accommodates the bearing member and the retainer, wherein the case has a piston that is axially movable so as to push a movable body, which is either the inner ring or the outer ring, in a first axial direction, an oil chamber provided on an opposite side of the piston from the movable body, and an oil passage for guiding pressurized oil to the oil chamber.

摘要： A work vehicle includes a driving wheel motor for driving at least one driving wheel, a working implement-related motor for driving at least one working implement, and at least one controller. The at least one controller sets, upon satisfaction of a predetermined condition set in advance, a relationship between vehicle speed of the work vehicle and working implement-related target rotational speed of the working implement-related motor to a working travelling cooperative relationship according to which the working implement-related target rotational speed is increased according to an increase in the vehicle speed at least within a predetermined vehicle speed range of the work vehicle, and controls the working implement-related motor to implement a working travelling cooperative mode in which the working implement-related motor is driven at the working implement-related target rotational speed based on the working travelling cooperative relationship.

摘要： An axle driving apparatus may include a first rotary shaft connected to an internal combustion engine; a second connected to an electric motor; a third rotary shaft connected to a driving shaft of a wheel; an interlocking unit interlocking the first, second, and third rotary shaft; and an input and output switchover unit. The interlocking unit and the input and output switchover unit are structured to switch the interlocking unit between a first mode in which only the power of the internal combustion engine is output from the third rotary shaft, a second mode in which only the power of the electric motor is output from the third rotary shaft, a third mode in which the power of the internal combustion engine and the power of the electric motor are combined and output from the third rotary shaft, and a fourth mode in which the power of the internal combustion engine is output from the second rotary shaft to the electric motor.
