Abstract: PROBLEM TO BE SOLVED: To provide a vehicle suspension device, adjusting the ground clearance depending on a state of the running road surface.
SOLUTION: This vehicle suspension device determines whether the vehicle is running on a bad road from the amount of electric power applied to a motor functioning as an electromagnetic absorber and the electric power application time (S12). In this vehicle suspension device, when a large amplitude variation in applied current to the motor continues for predetermined time or more, the road is determined to be bad. When the bad road is decided, the ground clearance is increased (S18) to prevent interference of the car body with the road surface. On the other hand, when the road is determined to be good, the stroke position of each wheel is adjusted so that the car body becomes parallel to the road surface.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle suspension device, efficiently avoiding stack and performing stable running.
SOLUTION: This vehicle suspension device is composed to determine whether a slip occurs in at least one wheel (S10). In this vehicle suspension device, when a slip occurs in one wheel (Y in S10), a motor of an electromagnetic suspension is driven for a very small amount of time in the direction of pressing another wheel to the grounding surface (S12). Thus, the grounding load of the wheels other than the wheel causing a slip is enlarged instantaneously (S14) to increase the driving force of the vehicle and avoid stack so that stable running of the vehicle can be realized (S16).

Abstract: PROBLEM TO BE SOLVED: To detect the relative displacement between an unsprung and a sprung of a vehicle in simple constitution. SOLUTION: In a vehicle including an absorber adapted to generate damping force between the sprung and the unsprung of the vehicle by rotating a ball screw mounted on the sprung of the vehicle engaged with a ball screw nut mounted on the unsprung of the vehicle by a rotating motor, an ECU mounted on the vehicle obtains a rotating angle of the motor detected by a rotating angle sensor (S10), and calculates a stroke of the ball screw from the rotating angle (S12). Further, the relative speed is calculated by time differentiation of the stroke (S14), and the relative acceleration is calculated by time differentiation of the relative speed (S16). The ECU controls the attitude of a car body on the basis of these values (S18). COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a control cylinder capable of rather easily and smoothly moving a piston assembly. SOLUTION: The piston 74 of the piston assembly 72 moving in a housing 70 is elastically supported by a piston support body 75. The piston support body 75 comprises a case 140 and a rubber member 132, and the rubber member 132 is interposed between the inner peripheral surface 140 of the piston 74 and the outer peripheral surface of a connection shaft 76. Accordingly, even if the relative position of the piston 74 to the inner peripheral surface 96 of the housing in the radial direction is displaced from the relative position thereof in the axial direction, the piston 74 can be displaced radially relative to the inner peripheral surface 96 thereof. Therefore, the displacement can be reduced. As a result, the control cylinder 10 with a rather small sliding resistance between the piston 74 and the housing 96 can be provided.

Abstract: PROBLEM TO BE SOLVED: To provide a control cylinder having control characteristic to meet an objective. SOLUTION: The control cylinder 10 controls a suspension cylinder 20 connected to each of four working fluid chambers 150 by the movement of a piston assembly 72 inside a housing 70. A connection shaft 76 of the piston assembly 72 is slidably brought into contact with a partition wall part 104 via an O-ring 114. The sliding resistance is increased when a large diameter part 140 provided at the center of the connection shaft 76 is slidably brought into contact with the partition wall part 104. In other words, when the piston assembly 72 is located at the neutral position in the control cylinder 10, the piston assembly 72 is hardly moved so that control of the suspension cylinder 20 is not performed unnecessarily. Thus, the control cylinder 10 can enhance the grounding property during the traveling on a rough road while maintaining the firm traveling feeling during the traveling on a smooth road.

Abstract: PROBLEM TO BE SOLVED: To reduce detection errors of a torque sensor caused by a size accuracy and an assembling error of slits by arranging the slits so that a part forming an overlap part of the slits is shorter than a straight part. SOLUTION: A length L1 in a diametrical direction of an output axis slit 34a is made larger than a length L2 in a diametrical direction of an input axis slit 32a at input output slit plates 32, 34. A part 34c forming an overlap part A of a side 34b is set shorter than a length of the side 34b which is a straight part. A change in area of the overlap part A to a shift of the slits in a specific direction is reduced accordingly. Even a minute size error at the straight part does not actually change the area of the overlap part A. In other words, a torque detection error to at least the size error of one slit can be reduced. Even if two slits minutely shift in a direction of the straight part, the area of the overlap part A does not change actually and the detection error is reduced.
