摘要： PURPOSE:To facilitate the starting operation by detecting the reverse revolution of the direction of action of a frictional force which acts between a brake frictional member and the frictional surface of a rotary body, when a car is allowed to stop on an ascent by the brake operation. CONSTITUTION:When a brake pedal 12 is stepped-in on an ascent, pressurized liquid is supplied into each wheel cylinder 2 of front wheels 14 and rear wheels 20 from a master cylinder 11, and shoes 4a and 4b are spread and press-attach onto a rotary body 5, and brake is applied. When a car stops, the turning moment in the opposite direction is applied onto the rotary body 5 which revolves with wheels. Therefore, the brake reaction force applied to the shoe 4b on the trailing side increases, and a slidable anchor 6 is pushed leftward, and a switch 9 is turned-ON through a rod 8. Therefore, a solenoid valve 8 is switched to the E-position, and the above-described pressurized liquid is held independently of the release of the stepping-in force of the brake pedal 12, and the car maintains the stop state.

摘要： PURPOSE:To miniaturize a disc brake in its entirety, by constituting a disc rotor with two rotors, and by disposing pads among a guide device and both rotors. CONSTITUTION:A disc rotor 18 has a first rotor 19, a second rotor 21 and pads 27-33, and is guided by a guide block, slidably along the axle. Accordingly, a piston 10 is made in press-contact with the second rotor 21 through a pad plate 33 and therefore, a caliper 2 is guided by a caliper guide device under reaction force to move in the axial direction so that a lining 28 is made in press-contact with the first rotor 19 through a pad plate 27. Therefore, four press-contact point are obtained between the disc rotor 18 and the pad, and therefore, a large brake torque may be obtained even if the diameter of the disc rotors 19, 21 are small, thereby it is possible to miniaturize the brake disc in its entirety.

摘要： PURPOSE:To make a brake holding valve so as to normally function all the time, by installing a spring rigging which comes into contact with a valve member before it touches an iron core when this valve member is attracted by an electromagnet unit. CONSTITUTION:When a coil 59 is energized with a continuous rating current, a valve element 31 is attracted to the side of an iron core 34, that is, moves to the side of the iron core 34 while compressing a spring 30 rolled on the circumference of a projection part 40a of a valve insertion plate 40, and it comes into contact with the iron core 34. Therefore, in a state that it touches the iron core 34, it receives sufficient large restoring force of a spring 90 and attracted to the iron core 34 to the full. When the coil 59 is unenergized out of the current, even if residual magnetism remains in the iron core 34 or the valve element 31, such a state of things that the valve element 31 and the iron core 34 are left attracted intact and the valve element 31 fails to move is avoidable without fail.

摘要： PURPOSE: To smoothly start a hydraulic actuator by providing a cylinder including a spring for pressing a pressure control spring of a pressure control valve and a releasing piston for pressing the spring with hydraulic pressure.
CONSTITUTION: When there is no pilot oil pressure in pilot circuits 9a, 9b, the pressure of pressure control valves 20a, 20b are set at a value corresponding to the pressing force of springs 22a, 22b, so that a hydraulic motor 4 is locked with storing force. When pilot oil pressure works upon the pilot circuit 9a, a direction changing valve 2 is located at a position 2b, and the pilot oil pressure works upon chambers 28a, 29a of a cylinder 23a to move a releasing piston 26a by a difference in pressure receiving areas therebetween, thereby pressing a spring 27a, so that the pressure of the valve 20a is set at a low value. When the piston 26a is brought into contact with a main body, the pressure in the chamber 28a increases, and the piston 25 is moved at a speed corresponding to a throttle 30 to press a pressure control spring 22a, so that the preset pressure of the valve 20a is increased until it corresponds to the pilot oil pressure.

摘要： PURPOSE:To reduce the number of component parts and thereby contrive to reduce weight and to simplify piping, by a method wherein a guide member for guiding a valve member for a supplying and discharging valve of a brake valve is constituted as a stepped piston, and the guide member is driven by a hydraulic signal. CONSTITUTION:When a brake pedal 80 is depressed, a controlling piston 40 is lowered through a plunger 70, so that the piston 40 is engaged to the valve member 60 and depress the latter downward. Therefore, a pressure fluid is fed to a brake gear through an input port 35 and an output port 36 to operate the brake gear. When operating the brake valve 30 without operating the pedal 80, the pressure fluid is supplied to a controlling input port 37 to pressurize the interior of an auxiliary controlling pressure chamber Y. As a result, the guide member 50 formed as a stepped piston is moved upward, the valve member 60 is engaged with the controlling piston 40, and a valve part 61 is separated from a valve seat 54. Accordingly, in a manner similar to the above, the pressure fluid is fed to the brake device through the input and output ports 35, 36 to operate the brake gear.

摘要： PURPOSE:To simultaneously effect the rises of braking actions in two systems and secure a braking action at the time of an abnormal condition, by a method wherein a valve gear is provided in a passage connecting two piping systems to each other, and is so operated as to open the passage in normal conditions and close the passage at the time of an abnormal condition. CONSTITUTION:When a braking operation is conducted in normal conditions, compressed air flows into passages 35, 36 of the valve gear 27 through the two piping systems 16, 17. When the pressure in the piping system 16 becomes higher than that in the other system due to a difference in air consumption quantity, a spool 41 is moved leftward. Since pistons 57, 60 are located at retracted positions by the pressure of a pressure source, the passages 35, 36 are communicated to each other through passages 52, 37., thereby equalizing the pressures in the passages 35, 36. When the pressure of the pressure source in the piping system 16 is lowered, the piston 57 is projected to come into contact with an O-ring 53, thereby closing the passage 51. Therefore, even when the spool 41 is moved rightward to communicate the passage 36 to the passage 51, compressed air in the passage 36 can not flow into the passage 35. Accordingly, a braking action in the normal piping system 17 is secured.
摘要翻译：目的：为了同时实现两个系统中的制动动作的上升，并且在异常状态时确保制动动作，通过在彼此连接两个管道系统的通路中设置有阀齿轮的方法，并且被操作在正常条件下打开通道，并在异常状态下关闭通道。构成：当在正常条件下进行制动操作时，压缩空气通过两个管道系统16,17流入阀齿轮27的通道35,36。当管道系统16中的压力变得高于其他系统由于空气消耗量的差异，阀芯41向左移动。由于活塞57,60通过压力源的压力位于缩回位置，通道35,36通过通道52,37彼此连通，从而使通道35,36中的压力相等。当压力管道系统16中的压力源下降，活塞57突出以与O形环53接触，从而关闭通道51.因此，即使当阀芯41向右移动以将通道36连通到通道51中，通道36中的压缩空气不能流入通道35.因此，确保了正常管道系统17中的制动作用。

摘要： PURPOSE:To synchronize rises in pressure even when the quantities of air consumed by driven devices in each system are different from each other, by connecting two piping systems through a bypass passage in accordance with a movement of a movable body receiving pressures of the two systems in opposite directions. CONSTITUTION:A valve gear 27 is integrally provided at an air pressure part 20 of a booster 18, is provided with a valve hole 31 for communicating a connecting hole 28 connected to a brake valve and a connecting hole 30 connected to a pressure chamber of another booster 19 with each other, and a valve body 32 is movably fitted in the valve hole 31. A stem part 36 of the valve body 32 projects into a pressure chamber 37 so that it can make contact with a piston 39. In braking, when the quantity of air consumed by the brake gear in the system of the booster 18 is large, the rise of pressure in the pressure chamber of the booster 19 is larger than that in the booster 18. Therefore, a difference is generated between the pressures exerted on the valve body 32, and the valve body 32 is separated from a seat 35. Accordingly, the pressures in the pressure chambers of the two boosters 18, 19 are equalized.
