摘要： PURPOSE:To improve the installing workability of a tube to a vehicle, in a tire pressure control device in which the tire side and the car body side are connected each other through the tube. CONSTITUTION:A hollow axle hub 42 is held rotatable to a hollow spindle 20 at the outer peripheral side of the spindle 20, and a wheel 50 is installed to the axle hub 42. A rotor 68 is fitted to be rotatable in the spindle 20 concentrically, and a connecting hole 94 is provided to the rotor 68 at the position eccentrically from the axial line. On the other hand, a connecting hole 110 is provided to the axle hub 42 in the condition connecting through the air valve 56 of the wheel 50 passing through a passage 108 and a tube 114. When the distance of the two connecting holes 94 and 110, and the distance of two connectors 96 and 120 of a tube 106 to connect them each other are not coincident each other, the connecting hole 94 is rotated an adequate angle around the rotating center of the wheel 50 by rotating the rotor 68, so as to install the tube 106 to the wheel 50.

摘要： PURPOSE:To improve the durability of a tire pressure control device by which the tire pressure of wheels can be controlled from the car body side in a car running condition. CONSTITUTION:A pressure control device 70 mainly consisting of a compressor 10, booster valves 42 to 46, and reducing valves 60 and 62, and controlled.by a controller 72, is connected to the tire inner chambers 26 and 36 of the right side and the left side wheels, passing through rotary air seal devices 22 and 32, and manual coaks 24 and 34. Furthermore, when the boosting speed of the pressure of the pressure control device 70, when the controller 72 is used for the tire pressure control, is fast abnormally, the tire control is stopped and the pressure is made at the atmosperic pressure. On the other hand, when the reducing speed of the pressure in the tire pressure controlling condition is fast abnormally, the pressure control device 70 is converted to the boosting operation, and when the boosting speed of the pressure at that time is fast abnormally, the tire pressure control is stopped making the pressure at the atmospheric pressure. And after that in either case, when the pressure becomes to the pressure of the releasing or higher, the tire pressure control is to be restarted.

Furthermore, the boosting speed of the pressure when the controller 72 is used in a boosting operation of the pressure control device 70 is calculated by using pressure sensors 18 and 28, and when the boosting speed is fast abnormally, it is decided that the manual cocks 24 and 34 are in the closed condition, and the boosting operation is stopped, and after that, the pressure is reduced to the atmospheric pressure. During the time when the manual cocks 24 and 34 are in the closed condition, the rotary air seal devices 22 and 32 are not to be under the pressure, and their durability is improved.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle abnormality detecting device capable of reducing the cost.
SOLUTION: This vehicle abnormality detecting device detects abnormality of an axle or a wheel of respective wheels based on a state amount of the respective wheels calculated from an output signal of a vehicle speed sensor provided on the respective wheels of the vehicle. Preferably, the vehicle abnormality detecting device calculates a reference state amount used for determining abnormality of the axle or the wheel of the respective wheels based on the state amount of the respective wheels in a predetermined time period, and the reference state amount and the state amount of the respective wheels are compared, and thereby it is determined whether the axle or the wheel of the respective wheels are abnormal or not.

摘要： PURPOSE:To control vibration of a vibration body having a frequency of a wide range by changing the frequency of a mass body as the mass of the mass body is kept at a constant value. CONSTITUTION:A vibration control device for a vibration body comprises a vibration sensor to detect the frequency of a vibration body 26; a dynamic absorber 22 attached to the vibration body; and a controller to input a signal from the vibration sensor. The dynamic absorber 22 comprises a movable mass body 32 formed of a permanent magnet; and an actuating mechanism 34 consisting of a core 38 applying a magnetic field, the intensity of which is regulatable, on a mass body 32 and continuously regulatable of the repulsion force of the mass body, and a coil 40. The controller is caused to regulate the repulsion force of the mass body 32 by operating the actuating mechanism 34 of the dynamic absorber and effect control so that the frequency of the mass body corresponding to the repulsion force is made equal to the frequency of the vibration body detected by the vibration sensor.

摘要： PURPOSE:To enhance balance at the time of rotation, and thereby stabilize valve opening by coaxially providing a part of an air passage and the valve body of a closing valve for the rotating center of a rotating member simultaneously rotating with a tire, and thereby providing a valve opening means which opens the valve through the axial movement of the means, for a non-rotating member in the outer circumference of the rotating member. CONSTITUTION:The stationary housing 51 of an air pressure regulating device is fixed at the tip end of a spindle section 16a in the knuckle 16 of a wheel 10. A rotating housing 53 is housed in the stationary housing 51, and an inner hole 53a is provided for a valve body 55, so that air flow in a space interspaced with a port 53b is thereby controlled. The valve body 55 is hermetically assembled in the axial center of the rotating housing 53 via seals 56 in such a way as to be freely moved in the axial direction, so that a closing valve V is thereby made up while the inner hole 53 is coaxially arranged. And a valve opening means B is arranged within the stationary housing 51 so as to be freely moved in the axial direction, and the means is constituted to act on the cruci-form arm 55a1 of a stay 55a, so that the closing valve V is thereby opened.
