摘要： A feed-forward control section controls, in a feed-forward manner, left and right hydraulic clutches CL and CR of a driving force distributing device by presuming such a driving force distribution amount DELTA T that a yaw rate corresponding to a turning state of a vehicle is obtained, based on an engine torque, an engine revolution-number, a vehicle speed, a steering angle and a lateral acceleration. On the other hand, a feedback control section calculates a deviation between a reference yaw rate calculated from the vehicle speed and the lateral acceleration and an actual yaw rate detected by a yaw rate sensor, and corrects the driving force distribution amount DELTA T calculating in the driving force distributing device in order to converge the deviation into zero. Therefore, even if the driving force distribution amount becomes excessive due to the feed-forward control to produce an over-steering tendency in the vehicle, this over-steering tendency can be eliminated by the feedback control to stabilize the behavior of the vehicle.

摘要： The present invention ensures that the warping of an annular disk body (2) of a brake disk (1), in the direction of a rotational axis (a), due to a friction heat, is inhibited to a large extent. The brake disk (1) includes an aluminum alloy matrix (6), a plurality of alumina aggregates (7) dispersed in the matrix (6), and a plurality of fine alumina grains (8). The alumina aggregates (7) have an aspect ratio A larger than 1. In an annular disk body (2), the alumina aggregates (7) are oriented with their lengthwise directions aligned with the radial direction of the disk body (2).

摘要： A power transmitting system of a four-wheel drive vehicle having primary driven wheels driven directly by a prime mover, and subsidiary driven wheels driven through a hydraulic clutch. The power transmitting system comprises a first hydraulic pump driven in operative association with the primary driven wheels and a second hydraulic pump driven in operative association with the subsidiary driven wheels. Each hydraulic pump has a pair of ports which serve as an intake and a discharge with the functions of such ports being reversed between forward and backward movement of the vehicle. A first oil passage connects the intake port of one pump with the discharge of the other pump and a second oil passage connects the discharge of the one pump with the intake of the other pump. Third and fourth oil passages connect the first and second oil passages, respectively, with a working hydraulic pressure chamber in the hydraulic clutch. A one-way valve is provided in each of the third and fourth oil passages for permitting only a flow of oil toward the working hydraulic pressure chamber. The reversal of vehicle movement and direction of oil discharged from each of the hydraulic pumps provided in the power transmitting system of the four-wheel drive vehicle is compensated for by a simple structure of oil passages and one-way valves.

摘要： A torque cam mechanism (61) comprises first and second cam members disposed relatively rotatably around a common axis and cam balls adapted to fit in first and second cam grooves formed, respectively, in confronting surfaces (62,63) of the first and second cam members. The depth (D1) of the first cam grooves is made larger than the radius (R) of the cam balls, whereas the depth of the second cam grooves (D2) is made smaller than the radius of the cam balls, whereby even though a centrifugal force is applied to the cam balls which rotate together with the first and second cam members, the generation of thrust forces for separating the confronting surfaces of the first and second cam members can be suppressed by receiving the centrifugal force so applied to the cam balls by the first cam grooves which are deeper.

摘要： The method involves determining the degree of distribution (Delta) of the drive force or braking force using a forward controller and reducing the degree of distribution using a feedback controller if an oversteer state is detected. The steps of determining and reducing the degree of distribution involve distributing the drive force or the braking force to the left and right wheels of the motor vehicle. The controls are applied via a pressure regulator (67) for a hydraulic pressure.
