摘要： The tire for automobiles being measured is loaded in advance by the load applying means and the drum is driven to rotate the tire. A displacement of the rotatable shaft produced in response to a variation in the radial force acting between the tire and the drum is detected as a displacement of the movable member. The movable member is movable with respect to the drum about a fulcrum which lies in or is located in the vicinity of a plane including a surface in which the drum and the tire are held against each other. Thus any influence by a moment due to a lateral force imposed on the tire can be eliminated, and the apparatus can measure a radial force variation with precision.

摘要： The automotive tire being measured is loaded in advance by the load applying means, and the drum is driven to rotate the tire. A displacement of the rotatable shaft produced in response to a variation in the radial force acting between the tire and the drum is detected as a displacement of the movable member which is in turn indicated as the radial force variation generated on the tire. Thus, the apparatus can measure a radial force variation with precision under a condition approximating an actual running condition of automobiles.

摘要： An active suspension apparatus detects a relative displacement (x) between an axle and a vehicle body, discriminates a road surface state in accordance with the relative displacement and a change rate (x) in unit time which is derived from the relative displacement (x), and optimally controls characteristics of damping forces of hydropneumatic suspensions in accordance with a discrimination result (i.e., a road surface state). This discrimination is performed in accordance with a sum (Ax+Bx) of a signal obtained by multiplying the relative displacement (x) with a predetermined coefficient and a signal obtained by multiplying the change rate (x) with another predetermined coefficient. These coefficients are obtained in accordance with riding comfort against vibrations. The characteristics of the damping force of the hydropneumatic suspension are controlled by controlling the opening of throttle valves disposed between hydropneumatic chambers and actuators.

摘要： A seat includes a seat frame, and a cushion material supported by the seat frame and having a three-dimensional knitted fabric which is formed by joining, with connecting threads, a pair of ground knit fabrics which are disposed so as to be separated from one another. The cushion material includes a first region whose elastic compliance when a reaction force is applied to an extending side of the cushion material when an occupant is seated on the seat is substantially equivalent to an elastic compliance of a portion of the occupant's body pressing the cushion material and a second region whose elastic compliance is larger than that of the first region. Accordingly, a thin and light seat can be provided, load concentration on the occupant's tuber ishiadicum bottom portion when seated for a long period of time can be mitigated, and vibration-transmitting characteristics can be improved.

摘要： An upper end portion of a seat backrest and a lower end portion of a head rest are superposed together. A rear end portion of an upper portion cushion member and a lower end portion of the seat backrest are superposed together. These superposed portions are sewn together by thin threads which break when pressing force of a predetermined value or greater is applied to the seat backrest. Thus, when pressing force of the predetermined value or greater is applied to the seat backrest, the thin threads break. A portion of the seat backrest which a shoulder portion of a seated occupant contacts, and a portion of the seat backrest which buttocks of the seated occupant contact, are enlarged, and impact force can be damped.

摘要： In this system for vehicle roll control, a plurality of duty radio controlled actuator assemblies are provided, one corresponding to each one of the vehicle wheels, and resiliently suspended from the vehicle body. These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding vehicle wheel as a result of the supplying or discharging of working fluid to or from its pressure chamber. Working fluid supplying and discharging means supply working fluid to and discharge working fluid from the pressure chambers of the actuator assemblies. The system further includes means for sensing the road speed of the vehicle, and means for sensing the steering angle of the vehicle. Vehicle height detection means are also provided for sensing the heights of the vehicle above the vehicle wheels. A means for computing and control calculates the deviations of the actual detected vehicle body heights from standard vehicle body heights; when a certain condition is satisfied, it controls the working fluid supplying and discharging means according to a first duty ratio according to the deviations of the actual vehicle body heights, so as to maintain the deviations of the actual vehicle body heights within predetermined ranges; and then it controls the working fluid supplying and discharging means in the reverse order according to a second duty ratio.

摘要： In a vibration control apparatus, a physical value influencing characteristics of a suspension for supporting a vibrating body and a state value representing movement of the suspension are detected. A frequency distribution of these values with respect to levels is calculated every predetermined period of time. A target control force is calculated on the basis of the frequency distribution in consideration of a continuous change in external state. An actual control force (detection control force) is calculated by the detected physical value. The suspension characteristics are continuously, variably controlled so as to equivalently generate a control force corresponding to a difference between the target and detection control forces. As a result, the target control force is equivalently applied to the suspension, thereby damping the vibrations. The vibration control apparatus can generate an optimal target control force free from the influence of an external state change on the basis of the frequency distribution of the state and physical values of the suspension.
