    Abstract: A control system for controlling change speed gearing (A) of a vehicle for transmitting output of an engine (1) in varied speeds to wheels. This system has a first clutch mechanism mounted in a drive transmitting line between the engine and the change speed gearing, the first clutch mechanism including two hydraulically operable clutches (5, 6) for forward drive and backward drive, and a backward-forward changeover valve (32) for selectively operating the two clutches; a second clutch mechanism mounted in a drive transmitting line between the change speed gearing and the wheels, the second clutch mechanism including a quick operating clutch (19) for quickly making and breaking drive transmission, and a clutch control valve (26) for controlling the quick operating clutch; actuators (T1, T2) for shifting the change speed gearing; and a control unit (30) operatively connected to the backward-forward changeover valve, clutch control valve and actuators. In response to start of a shifting operation of the actuators, the quick operating clutch is disengaged and an engaged one of the hydraulically operable clutches of the first clutch mechanism is reduced to a predetermined low pressure. In response to completion of the shifting operation of the actuators, the quick operating clutch is engaged and the clutch of the first clutch mechanism is gradually raised from the predetermined low pressure.

    Abstract: A power transmission comprising a drive shaft and a driven shaft connected to each other to be relatively rotatable within a predetermined range. The connection between the two shafts includes a cam member axially slidable on the driven shaft. The driven shaft carries a brake device interlocked with the cam member. When an accelerating force is transmitted from ground wheels to the driven shaft, the cam member slides axially of the driven shaft. This sliding movement causes the brake device to brake the driven shaft.

    Abstract: A rolling clutch apparatus having two one-way transmission mechanisms arranged axially of a drive shaft and a driven shaft. Each transmission mechanism includes an inner ring defining a conical outside surface, an outer ring disposed coaxially with the inner ring and defining a conical inside surface, and tapered rollers arranged between the conical surfaces of the inner and outer rings. The transmission mechanisms are shiftable at the same time so that the rollers in one of the transmission mechanisms are displaced axilly to be pressed between the conical surfaces of the inner and outer rings whereby the inner and outer rings rotate together to transmit drive.

    Abstract: A four wheel drive working vehicle having transmission clutches separately operable for driving right and left rear wheels. Power for driving right and left front wheels is transmitted thereto from a change speed device through a front differential, while power for driving the rear wheels is transmitted thereto from the change speed device through the transmission clutches, respectively. When the front wheels are steered from a straight running position beyond a predetermined angle in order to turn the vehicle, the transmission clutch corresponding to the rear wheel lying on the inside of the turn is disengaged while the transmission clutch corresponding to the outside rear wheel remains engaged. Consequently, the rear wheel lying on the inside of the turn and describing the smallest turning radius is placed in free rotation state. The working vehicle can change running directions and make small, sharp turns smoothly without a rear differential.
