摘要： PURPOSE:To improve response without sacrifice of comfortableness by coupling the head side oil chamber of a hydraulic cylinder through a communication path changeover valve to the output port of a pressure control means or an accumulator, while coupling the rod side oil chamber to the output port of the pressure control means. CONSTITUTION:Ports 51A, 51B of a changeover valve 51 are communicated during normal linear traveling. When the rod 90 of a hydraulic cylinder 81 contracts, working oil in the head side oil chamber 23b passes through a piping 113, the changeover valve 51, a piping 107 and a damping force valve 61 and accumulated in an accumulator 71, which feeds the working oil to a rod side oil chamber 23b. The working oil is discharged when the rod 90 extends. When attitude variation control is carried out, communication of ports of the changeover valves 51-54 is switched to carry out telescope control of the hydraulic cylinders 81-84. By such arrangement, attitude control of vehicle is carried out with high response, resulting in the reduction of energy loss of pump.

摘要： PURPOSE:To make stable power transmission performable, by giving turning force in a direction of winding a tension wire to a winding rotor at all times by the spring member stretched across a space between a tension rotor and the winding rotor. CONSTITUTION:For example, a pulley 3 at the input side pressed plural driving blocks 30 forcibly between a fixed pulley 10 and a moving pulley 20 making a pulley space variable with hydraulic pressure in a hydraulic chamber 20a, and it performs power transmission with an endless belt 5 being wrapped on these blocks. These driving blocks 30 are attracted toward an input shaft 1 by a tension wire 8 being rolled on the winding rotor 83 fitted in a tension rotor 84 free of rotation. This winding rotor 83 is always given turning force in a direction of winding the tension wire 80 by dint of the coil spring 85 stretched across a space between both these rotors 83 and 84. Thus, each driving block can be highly accurately positioned in a radial regular position, so that its durability is improved.

摘要： PURPOSE:To apply the optimal force onto each wheel and to support the attitude of a vehicle stably by arranging a variable pressure regulator, a modulator and a cut valve for every wheel, then controlling to supply the optimal pressure to each wheel cylinder. CONSTITUTION:Cut valves 310-340 and modulators 410-440 are arranged respectively in the way of hydraulic pipings for coupling respective wheels 105-111 with a master cylinder 103 coupled to a brake pedal 101. While variable pressure regulators 210-240 are arranged respectively at the joints of a hydraulic pump 117 and the lead-in pipings 170. The operation is explained referring to the right side of a front wheel as follows. On the basis of a detection signal from a wheel sensor arranged on a wheel, a switching signal is fed from an electronic controller to the variable pressure regulator 210 to control the pressure in an input chamber 412 of the modulator 140. Then a movable piston 411 is pushed by the pressure led into the input chamber 412 to produce a pressure in an output chamber 413 which is fed to a wheel cylinder 105. When the pressure is being fed, the conduit between the master cylinder 103 and the wheel cylinder 105 is closed by means of a cut valve 310.

摘要： PURPOSE:To perform an operational check on a valve, by making a control valve, which lowers the extent of braking pressure if starting operation is made out of a car stopping stage, open for the specified time long and then opening a selector valve between a pressure generating device and a braking device. CONSTITUTION:When a wheel speed is slower than the setting car speed and a brake pedal 1 is operated, it is judged as stoppage whereby a selector valve 40 is switched to a second position, keeping pressure in each of wheel cylinders 4 and 5. And, in case of a torque converter type automatic transmission, when a shift lever is in a running range position and an accelerator pedal is operated, it is judged as a starting state. At this time, control valves 41 and 42 is switched to the second position for the specified time long, releasing the pressure in these wheel cylinders 4 and 5, and starting is made performable. After that, the selector valve 40 is switched to a first position.

摘要： PURPOSE:To reduce force applied to driving blocks, by radially forming slits on fixed and movable pulleys and providing the driving blocks movable in the diametric direction along the slits. CONSTITUTION:A fixed pulley 1, forming an iron system alloy into a polygonal pyramid, radially forms linear slits 1a respectively in pulley surfaces 100. Cementation treatment is applied as a surface hardening process to both internal side surfaces of the pulley surface 100 and the linear slit, further the surface decreases surface roughness as small as possible by polishing. While a transmission fixes a fixed flange 8 to a shaft 3 further provides a movable pulley 2, having a pulley surface 200 of polygonal pyramid, in the side of a movable pulley unit 203. Said movable pulley 2 radially provides slits 2a similar to the fixed pulley 1. The transmission, holding a flat belt 6 by plural driving blocks 4, slidably fits the driving blocks 4 into the slits 1a, 2a.

摘要： PURPOSE:To aim at a performance improvement, by altering the setting value of braking hydraulic pressure in consecutive order so as to secure a desired slip factor, and adopting such a learning control system as securing the desired slip factor eventually. CONSTITUTION:Each detection signal out of car speed sensors 5-8 is inputted into an electronic control circuit 18 in which a judgement of antiskid control takes place. Solenoid valves 24a, 38a and 38d are selected by each of driving signals 18a-18d whereby a motor 30 is driven and braking hydraulic pressure is supplied. When the solenoid valve 24a is selected, a master cylinder 15 and each of wheel cylinders 9 and 12 are all intercepted, therefore these solenoid valves 38a and 38d are selected and these wheel cylinders 9 and 12 are decompressed. Afterward, hydraulic pressure in a hydraulic pump 31a is taken in, making the braking hydraulic pressure go up. Thus, the braking hydraulic pressure in these wheel cylinders 9 and 12 is controlled for increase or decrease whereby antiskid control is carried out.
