Abstract: PURPOSE:To enable damping force to be controlled consecutively and exactly by proportioning reversely to the square root of a spool displacement the variable-aperture-passage-cross-sectional-area of an orifice connecting the hollow- hole of a valve main-body and the outside. CONSTITUTION:When a vehicle bonds, oil inside a cylinder chamber flows to an oil chamber via a passage 80, the variable aperture 30 of an orifice 18 formed at a sleeve 10, the annular passage 28 of a spool 16, a passage 20, an annular groove 50, a passage 68, and damping force occurs. This orifice 18, together with the land portion 22 of the spool 16 which is positioned through a core-rod 64 according to a travel condition, forms the variable aperture in which a cross-sectional area A is variable. In this case, the variable aperture cross-sectional area A is formed so as to be reversely proportionate to the square root of a displacement X off the standard position O of the spool 16, and a flow-quantity coefficient is retained nearly fixedly. Thus, damping force can be set exactly at a proper value according to the travel condition of a vehicle.

Abstract: PROBLEM TO BE SOLVED: To obtain a load-diplacement characteristic with small hysteresis, in a heavy Belleville spring piled up in parallel. SOLUTION: A plurality of belleville springs 10 are piled up in parallel. The surface roughness of the mating surface of each Belleville spring 10 is within a range not less than Rmax 1.0 and not more than 2.0. A different material pile is prepared between each Belleville spring 10. If the surface roughness in this range, a loss of a force of the Belleville spring 10 dependent on rubbing can be made small. Moreover, if a different material pile is prepared between each Belleville spring 10, the characteristic is not deteriorated by the activity of a long time, either. By this, the load-displacement with characteristic small hysteresis can be obtained for a long period of time. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PURPOSE:To improve short turning performance of a vehicle and to ensure stable turning performance by a method wherein only when the steering angle of front wheels exceeds a given value, steering is controlled so that the steering angle of rear wheels is increased in an opposite phase proportionally to that of the front wheels. CONSTITUTION:When a rear wheel steering cancel switch 52 is, for example, turned OFF, since a solenoid switching valve 51 is in a first state, working oil is fed through a flow dividing valve 23 to a spool valve 42 with the aid of a hydraulic pump 22, and left and right rear wheels RW1 and RW2 are steered in linkage with steering of left and right front wheels FW1 and FW2. When a steering handle 14 is rotated, for example, rightward, left and right front wheels FW1 and FW2 are steered rightward through a rack bar 11, a cable 68 is pulled, and left and right rear wheels RW1 and RW2 are steered leftward through a relay rod 31. In this case, when a front wheel steering angle, for example, exceeds a given value, rear wheels are controlled in an opposite phase proportionally to front wheels.
