摘要： A vehicle rear suspension system having a vertically swingable arm connected at the front end swingably to the vehicle body and secured at the rear end to a wheel carrying member which carries a rear wheel for rotation. Three lateral links ar provided and have inward ends pivotably connected to the vehicle body and outward ends pivotably connected to the wheel carrying member. The points of connection of the three lateral links to the wheel carrying member are not aligned in a straight line so that the orientation of the wheel carrying member can appropriately be controlled under bump and rebouncing movements of the rear wheel and under side and longitudinal forces acting on the rear wheel.

摘要： A vehicle rear suspension system having a vergically swingable arm connected at the front end swingably to the vehicle body and secured at the rear end to a wheel carrying member which carries a rare wheel for rotation. Three lateral links are provided and have inward ends pivotably connected to the vehicle body and outward ends pivotably connected to the wheel carrying member. The points of connection of the three lateral links to the wheel carrying member are not aligned in a straight line so that the orientation of the wheel carrying member can appropriately be controlled under bump and rebouncing movements of the rear wheel and under side and longitudinal forces acting on the rear wheel.

摘要： A vehicle rear suspension system includes a wheel carrying member for rotatably carrying a wheel of a vehicle, three lateral links extending in a transverse direction and connected with the wheel carrying member at their outer ends, and a trailing arm extending in a longitudinal direction. The trailing arm is connected with a body member of the vehicle at front end through a single joint. The trailing arm is formed with biforked portions, at a rear end, extending in the up and down direction. One of the biforked portions is connected with a lower one of the three lateral link and the other of the biforked portions is connected with an upper one of the three lateral links or the wheel carrying member. The number of connecting points or joints between the trailing arm and the wheel carrying member can be reduced with an improved controllability of wheel attitude.

摘要： Suspension mechanisms for motor vehicles include dampers of variable damping powers and air springs of variable spring coefficients so that the suspension characteristics are changed between soft and hard modes. The suspension mechanisms are provided with a controller for producing a control signal only when the differential value between the value of a last steering angle and an average value of steering angles is larger than a predetermined value to change the suspension characteristics to the hard mode. In accordance with this arrangement, the suspension characteristics are changed to the hard mode only when the rolling angle of the vehicle exceeds a predetermined value.

摘要： A rear suspension apparatus for an automotive vehicle includes a rear wheel support the front and rear ends of which are resiliently supported on the vehicle chassis. The elastic characteristic of the resilient support is such that the front end of the wheel support readily deflects from the outward to the inward side of the vehicle chassis. The resilient support system resiliently supporting the rear end of the wheel support is set in such a manner that the rear end of the wheel support will readily deflect from the inward to the outward side of the vehicle chassis.

摘要： A vehicle suspension system having suspension mechanisms including damping struts of variable damping rates and air springs of variable spring coefficients so that the suspension characteristics are changed between the "hard" and "soft" modes. A control circuit is provided for producing a control signal when the engine power output is substantially greater than the engine load to change the suspension characteristics into the "hard" mode. The arrangement is effective to prevent a rearward pitching of the vehicle in start or rapid acceleration.

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.

摘要： In a suspension system for a vehicle, each of front and rear suspensions for respectively supporting the front and rear wheels is connected to the vehicle body by way of an adjustable-height supporting member which supports the vehicle body to be variable in height, and at the same time, the front and rear suspensions are arranged so that the rate of change of the roll center height due to bump/rebound is larger in the rear suspension than in the front suspension. The adjustable-height supporting member is controlled to change the vehicle height according to the vehicle speed to be higher during low speed travel than during high speed travel.
