摘要： Changeover clutch discs for a direct coupling clutch and a change-speed clutch, respectively, are disposed in two stages in a radial direction across a movable element which can move in axial directions of an input shaft. A carrier and the movable element are brought into meshing engagement with each other such that the movable element does not rotate relative to the carrier. The changeover clutch discs mesh with clutch discs which are disposed on the input shaft and a casing, respectively. A coned disc spring and an electromagnetic actuator are disposed such that operating directions of the spring and the actuator are opposed to each other. The coned disc spring keeps the direct coupling clutch in a normally engaged condition with its biasing force, and the electromagnetic actuator brings a change-speed clutch into engagement after it has released the engagement of the direct coupling clutch by virtue of its thrust.

摘要： In a steering control system for controlling torque steer in a vehicle equipped with an electric power steering device and a torque split arrangement for individually controlling traction and/or braking force of right and left wheels, a difference in traction and/or braking force between the right and left wheels which may be produced by the torque split arrangement may give rise to torque steer depending on the geometry of the wheel suspension system of the vehicle. The control unit for the electric power steering device additionally receives an additional signal for providing an additional steering torque which is required for canceling the torque steer. Thus, the torque steer can be eliminated both economically and reliably without requiring to modify the wheel suspension system.

摘要： A feed-forward control section controls, in a feed-forward manner, left and right hydraulic clutches C.sub.L and C.sub.R 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： In a vehicle including a torque distributing device for distributing the torque of an engine to left and right driving wheels, a feed-forward control system determines a lateral distribution torque T.sub.1 from an engine torque T.sub.E, a number Ne of revolutions of the engine, a vehicle speed V and a steering angle .theta., and a feed-back control system determines a feed-back torque T.sub.F from a target yaw rate Y determined from the vehicle speed V and the steering angle .theta. and an actual yaw rate Yaw. A final distribution torque T is determined by adding the lateral distribution torque T.sub.1 and the feed-back torque T.sub.D at a predetermined ratio, and an actuator is driven to distribute the engine torque to the left and right driving wheels on the basis of the final distribution torque T. Thus, it is possible to appropriately distribute the engine torque to the left and right driving wheels, and to allow the actual yaw rate of the vehicle to be matched with the target yaw rate to improve the steering characteristic.

摘要： In a rear suspension system of an automobile, a pair of left and right trailing arms for rear wheels have forward extension arms which extend forwardly past the pivot portions of the trailing arms to the automobile body and the front ends of the extension arms are relatively swingably connected to ends of a relay rod which is resiliently displaceable in the lateral direction of the body through compensator arms inclined inwardly at their front ends. This permits a "toe-in" to be given to each rear wheel when the automobile turns with brake being effected, whereas when the wheels are running on road surfaces of largely different coefficients of friction during braking, a "toe-out" is given to one rear wheel associated with the road surface of higher coefficient of friction.

摘要： A rotatable grip (ancillary operation member) is provided on a part of a steering wheel body of a steering wheel (main operation member) for turning wheels. When the grip is rotated, a difference is generated between left and right wheels, and a yaw moment generated with this difference can assist or suppress the turning of a vehicle. Because the grip constitutes a part of the steering wheel body, it is possible to rotate the grip to assist or suppress the turning of the vehicle, while operating the steering wheel to turn the vehicle. Because both the steering wheel body and the grip can be operated by the same hand of a driver, operational burden on the driver is alleviated. Thus, it is possible to concurrently provide an excellent operability of the main operation member for controlling a kinetic state of the vehicle, and an excellent operability of the ancillary operation member for controlling the operation of a yaw moment generating device.

摘要： In a four wheel steering vehicle, the rear wheels are steered so as to reduce a magnitude of the vehicle body side slip angular speed. Thus, whenever there is a rise in the vehicle body side slip angle which is directed outward with respect to the turning circle of the vehicle at an early stage of turning operation, the rear wheels are steered in opposite sense to the front wheel steering angle. Therefore, the vehicle body side slip angle is at least partly canceled, and this in turn increases the yaw moment and produces a sharp heading response. As the vehicle continues the turning operation, the rear wheels are steered in the same phase as the front wheels, thereby offsetting the tendency of the vehicle to go into a spin. When the vehicle is turning at a steady rate without incurring any change in the vehicle body side slip angle, the rear wheels are not steered, and the vehicle essentially behaves as if it were a front wheel steering vehicle.

摘要： In a power transmitting system for distributing a torque to left and right driving wheels in a front engine and front drive vehicle, a transmission is connected to one end of an engine which is horizontally disposed at a front portion of a vehicle body, and a planetary gear type differential is disposed in a space provided in the rear of the transmission. A first clutch and a second clutch are disposed laterally side by side in a space provided in the rear of the engine for controlling the torque transmitted to left and right front wheels by increasing and transmitting the rotation of a ring gear, which is an input member of the differential, to a left axle or a right axle. Thus, the pair of left and right clutches, added to the differential, can be rationally disposed by effective utilization of the spaces.
