摘要： In a suspension system for a vehicle constructed to change toe angle of wheels when receiving a lateral force, delay means for delaying toe angle change is provided at one of these: a front lateral link, a rear lateral link, and a trailing link. This structure results in a rapid cornering at an initial stage of cornering and a stability of wheels thereafter can be planned.

摘要： A vehicle rear suspension system including a wheel hub supporting a rear wheel for rotation, a front lateral link extending transversely and connected through a front inner rubber bush with the vehicle body and through a front outer rubber bush with the wheel hub, a rear lateral link extending transversely and connected through a rear inner rubber bush with the vehicle body and through a rear outer rubber bush with the wheel hub. The rubber bushes have resiliencies such that deflections are produced under a transversely inwardly directed side force applied to the wheel from a road on which the wheel is running to produce a change in a toe direction of the wheel in a manner that the toe direction is changed with respect to an increase in the side force with a first rate under a first range of the side force, with a second rate which is smaller in a sense of toe-in direction that the first rate under a second range of the side force which is larger than the first range and with a third rate which is larger in a sense of toe-in direction than the second rate under a third range of the side force which is larger than the second range.

摘要： Two support members which are supported swingably to the vehicle body through the medium of the support axis extending in up and down direction are provided at the vehicle body end portions of two left and right suspension arm members connecting left and right rear wheels to the vehicle body. Lever parts are extended from the support members toward the opposing direction to each other and are interconnected by a link member. One of the two support members is driven by one actuator for rotation around an support axis, whereby left and right two suspension arm members move in vehicle widthwise direction, opposite to each other, and in synchronism with each other and thus left and right rear wheels are steered symmetrically in toe-in direction or toe-out direction. Since the motive power mechanism part is of simple construction using link members, and engaging parts of gears can be lessened, the device according to the present invention can contribute to compactness and cost reduction and also can restrict "shaking" in rear wheel steering due to backlash of gears.

摘要： A suspension system has a link mechanism, disposed between a wheel support and a car body, for suspending the wheel support from the body so as to allow a wheel, related to steering, to swing about a center axis relative to the body. The link mechanism is caused to change a height of an instantaneous center of a swing of the wheel from the ground according to degrees of turn, such as steered angles, so as to maintain a height of the instantaneous center at a substantially fixed height from the ground.

摘要： A rear suspension system for a four-wheel-steered vehicle has a wheel support which supports a rear wheel for rotation and is connected to a rear wheel turning rod of the rear wheel turning mechanism. A pair of suspension arms are connected to the wheel support and guide the wheel support so that the rear wheel on the wheel support is turned about a kingpin axis in response to displacement of the rear wheel turning rod member. One of the suspension arms includes a so-called I-shaped arm which is connected for rotation to the wheel support at one end and to the vehicle body at the other end, and the kingpin axis intersects the tread of the rear wheel at a point which is offset in the longitudinal direction of the vehicle body from the point at which a side force acts on the rear wheel during cornering. A damping system is connected between the I-shaped arm and the vehicle body. The I-shaped arm is positioned so that the counterforce of the damping system generates a moment which tends to turn the rear wheel in the direction opposite to the direction in which the moment generated by the side force acting on the rear wheel when the vehicle corners with the rear wheel being the outer wheel tends to turn the rear wheel.

摘要： A vehicle suspension system comprises a wheel carrying member for rotatably carrying a wheel of a vehicle. The wheel carrying member is provided with an extension extending upwardly. A first upper arm member extends in a substantially longitudinal direction of the vehicle and is pivotally connected at one end with an upper end portion of said the extension and at the other end with a vehicle body member. A second upper arm member is arranged downward of the first upper arm member, extending in a substantially transverse direction of the vehicle and pivotally connected at one end with the wheel carrying member and at the other end with the vehicle body member. A lower arm is connected at one end with a lower portion of the wheel carrying member and at the other end with the vehicle body member for restricting at least a longitudinal and transverse movement of the wheel carrying member. A desirable camber and caster angle control can be accomplished.

摘要： A wheel support rotatably supports a dirigible wheel. An upper wheel-support support member connects an upper portion of the wheel support to the vehicle body, and a lower wheel-support support member connects a lower portion of the wheel support to the vehicle body. The upper and lower wheel-support support members are arranged to respectively define upper and lower pivot points which define an imaginary kingpin axis. At least one of the upper and lower wheel-support support members is formed of a pair of separate link members one end of each of which is pivoted on the vehicle body at different portions of the vehicle body and the other end of each of which is rotatably connected to the wheel support at different portions of the wheel support. The upper and lower wheel-support support members are arranged so that the upper portion of the wheel support is displaced more inward than the lower portion thereof when the wheel makes a turn as the outer wheel, and so that the upper portion of the wheel support is displaced less inward than than the lowr portion thereof when the wheel makes a turn as the inner wheel.

摘要： A suspension apparatus of a vehicle has a cylinder unit interposed between a sprang weight and an unsprung weight, which changes a ride height of the vehicle body by supplying or discharging an operating liquid through a supply/discharge control valve. The supply/discharge control value is controlled on the basis of a predetermined condition so as to control a posture of the vehicle body. There are further provided a rebound detecting sensor for detecting a rebound of each of the wheels, which occurs further from a state in which the wheel is rebounded, and a pressure detecting sensor for detecting a pressure in the cylinder unit. When it is sensed by the rebound detecting sensor that the rebound occurs further from the rebounding state, if the pressure detected by the pressure detecting sensor is continued in an elevating state for a given period of time, it is judged that the supply/discharge control valve is in trouble.

摘要： In a rear suspension system for a four-wheel-steered vehicle, each wheel support is connected to a rear wheel turning rod so that the rear wheel on the wheel support is turned about a king pin axis when the rear wheel turning rod is displaced. Upper and lower arms define the king pin axis, and the rear wheel on the wheel support is turned about the king pin axis in response to displacement of the rear wheel turning rod. The king pin axis is tilted inward from the vertical and intersects the tread of the rear wheel at a point which is longitudinally offset from the point at which a side force acts on the rear wheel during cornering. A coil spring is connected between the wheel support and the vehicle body and restrains vertical motion of the wheel support under the counterforce thereof. The line of action of the counterforce is tilted with respect to the king pin axis so that it is not parallel to the king pin axis, does not intersect the king pin axis and is directed such that the counterforce generates a moment which tends to turn the rear wheel in the direction opposite to the direction in which the moment generated by the side force acting on the outer of the rear wheels tends to turn the outer rear wheel when the vehicle corners.
