摘要： PURPOSE:To automate a return to the initial state during supplying of air by forming a wire pressure detecting device by a movable member having a magnetic material capable of moving by centrifugal force or vibration, a means for switching the movable member to a locked or loosened state, and means for detecting magnetic flux of the magnetic material to judge whether the magnetic flux is regular or irregular. CONSTITUTION:Air pressure in an internal air chamber 49 is increased or decreased by the tire internal pressure to expand or contrast a bellows part 51 to lock or loosen a magnet-presser part 53 and a cap 57 to/from a spherical magnet 55. When the spherical magnet 55 is loosened due to the tire pressure drop, it is moved at random by centrifugal force or vibration. A magnetism detecting unit 31 detects the movement of the magnet to judge the tire pressure drop. On the one hand, when air is injected, the spherical magnet 55 is locked to any position by the magnet-presser 53 and the cap 57. Thus, signals detected by the magnetism detecting unit 31 are stabilized during travelling so that it is judged whether the air pressure is normal or not. As a result, a return to the initial state is automated.

摘要： PURPOSE:To secure a pressure accumulation value in a stable manner, by driving a pressure oil generating means when the pressure accumulation value of an accumulating means storing working hydraulic pressure to be fed to a wheel cylinder is insufficient, and making the pressure accumulation so as to be completed at a time when the pressure accumulation value goes up beyond the setting value over plural times. CONSTITUTION:Hydraulic fluid in an oil storage means 1 is pressurized by a pressure oil generating means 2, and there is provided with an accumulating means 3 storing the discharge oil. And, when a switching means 5 to be controlled by a controlling means 6 according to a slip state of a driving wheel 4 is in a first switching state, each pressure oil out of the pressure oil generating means 2 and the accumulating means 3 is given to a wheel cylinder 4a, while when it is in a second switching state, the hydraulic fluid out of the oil storage means 1 leading to the pressure oil generating means 2 is allowed to be given. And, when pressure of accumulated oil of the accumulating means 3 is detected by a detecting means 7 and it is judged to be pressure shortage by a first judging means 8, the pressure oil generating means 2 is driven, and when it is so judged that the pressure detected value exceeds the specified value over several times by a second judging means 9, the pressure oil generating device 2 is stopped.

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 prevent function of an automatic brake against temporal stoppage for putting into a barn by producing an output signal with a time lag against the stop detection signal during occurrence of a back speed change position detecting signal. CONSTITUTION:It is comprising an automatic parking brake system, a parking brake mechanism 10, a motor mechanism 20 and an electric control circuit 30. A microcomputer 37 in said circuit 30 is fed power from a D.C. power source B to be in normally operating condition thus to perform operation. When stopping during travel while shifting an automatic transmission to reverse range under circulating operation, brake will function on the basis of the function of a motor mechanism 20 automatically with correspondence to the forward function of the motor mechanism 20 with predetermined time lag from stoppage operated through the microcomputer 37, thereby the operator can prevent troublesome brake operation.

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.

CONSTITUTION:A pressure detecting part 29 which is fitted to a rim 3 and air in a tire 1 is introduced in it, is provided with a casing 39 thread-mounted to the rim 3, and the flange part 47 of a bellows 45 expanding due to the inner pressure of the tire is pinchedly held by the thread-mount of the casing 39. A cap 57 fitted to the casing 39 is provided, and a globular magnet 55 as a responsible member for centrifugal force is received in the space 59 defined in the interior, and held with the bellows 45. The globular magnet 55 is constructed by molding a magnet 55a with resin 55b, and a permanent magnet 60 as a holding means is fixed on the rim 3 at the opposing position to the N-pole of the globular magnet. The condition of air pressure in the tire is judged by output of a magnetism detecting part 31 to detect the position of the magnet 55.

摘要： PURPOSE:To improve high speed and low speed performance by adjusting ground contact area large and small according to the expansion and shrinkage of a tire by providing a holding member for holding the form of a part of the portion corresponding to the ground contact face of the tire opposing the expansion of the tire caused by air pressure to the part mentioned above. CONSTITUTION:A holding member 3, the ring like piano wire 3 buried in the center section of the tire, for example, for holding the form of a part of the portion corresponding to the ground contact face of a tire 1 opposing the expansion of the tire 1 caused by air pressure is provided to the part mentioned above. In addition, the air pressure adjusting device 7 provided close to the rim section 5 of the tire performs adjusting control based on the various detected signals fro. a car speed sensor 11 and rain drop sensor 13 by means of an air pressure control device 9. In addition, when the air pressure of the tire 1 was adjusted high and low, the form of the portion on which the form holding member 3 is arranged is held constant, on the other hand, the form of the portion other than this portion is expanded and contracted. Thus, the whole form of the ground contact face is changed to adjust the ground contact area, large and small.
