    • A swash-plate plunger-type hydraulic device has a cylinder block with a plurality of plungers slidably fitted in cylinder bores, a swash plate confronting one end of the cylinder block, and a distribution valve plate slidably held against the other end of the cylinder block. The cylinder block has an even number of circularly arrayed connecting ports communicating with the cylinder bores and opening at the other end thereof. The distribution valve plate has inlet and outlet ports. The cylinder block is rotatable through an angular displacement .theta.1 in which the hydraulic pressure in one connecting port between the inlet and outlet ports increases from a lower pressure to a higher pressure, through an angular displacement .theta.2 in which the hydraulic pressure in one connecting port between the inlet and output ports decreases from the higher pressure to the lower pressure, and through an angular displacement .theta.3 from a position where the hydraulic pressure starts to increase to a position where the hydraulic pressure starts to decrease. The inlet and outlet ports are defined such that the angular displacements .theta.1, .theta.2, .theta.3 are expressed by:.theta.1=.theta.2 and .theta.3=180.degree..

    • A process for controlling a yaw moment in a vehicle by generating a braking force in one of the left and right wheels of the vehicle and by generating a driving force in the other wheel. When a vehicle is accelerated during the turning thereof, grounding loads of rear wheels are increased in order to generate a yaw moment in a direction opposite from a turning direction. However, such yaw moment can be eliminated in order to enhance the turning performance by bringing one of the hydraulic clutches into an engaged state with a torque which is proportional to a product of longitudinal and lateral accelerations. Consequently, a braking force and a driving force in inner and outer wheels during turning of the vehicle, respectively, are generated. When the vehicle is decelerated during turning thereof, grounding loads of front wheels are increased to a yaw moment in the same direction as the turning direction. However, such yaw moment can be eliminated in order to enhance the high-speed stable performance by bringing one of the hydraulic clutches into an engaged state with a torque which is proportional to longitudinal and lateral accelerations. Thus, when the vehicle is accelerated or decelerated during the turning thereof, the generation of an undesired yaw moment can be avoided in order to insure the turning performance and the high-speed stable performance.
    • 一种通过在车辆的左右车轮之一产生制动力并通过在另一车轮中产生驱动力来控制车辆中的横摆力矩的过程。 当车辆在转动期间被加速时,后轮的接地负荷增加,以产生与转向方向相反的方向的横摆力矩。 然而,为了通过将一个液压离合器以与纵向和横向加速度的乘积成正比的扭矩进入接合状态来提高转向性能,可以消除这种偏转力矩。 因此,产生分别在车辆转动期间的内轮和外轮的制动力和驱动力。 当车辆在转动期间减速时,前轮的接地负荷在与转向方向相同的方向上增加到横摆力矩。 然而,为了通过使一个液压离合器以与纵向和横向加速度成比例的扭矩进入接合状态来提高高速稳定性能,可以消除这种偏转力矩。 因此,当车辆在转弯期间被加速或减速时,为了确保转弯性能和高速稳定性能,可以避免产生不期望的横摆力矩。
