摘要： PURPOSE:To reduce the generation of noise caused by the backlash of gears to the utmost and heighten the transmission accuracy of the angle of rotation in a rear wheel steering system. CONSTITUTION:The rotation of a motor 20 is transmitted to a relay rod 11 through planetary roller mechanism 30 forming reduction mechanism and through ball screw mechanism 40 for converting rotation into linear motion, and lateral rear wheels RW1, RW2 are steered by the axial displacement of the rod 11 according to the rotation of the motor 20. Since a sun roller, a planetary roller and a ring roller 33 forming the planetary roller mechanism 30 are respectively friction-engaged so as not to use gears, the generation of noise caused by the backlash of gears can be prevented, and the transmission accuracy of the angle of rotation can be heightened.

摘要： PURPOSE:To enhance the assembly operation of the title box by a method wherein a tube part which is passed through, and mounted on, a vehicle-body opening and which makes the inner side of a vehicle chamber communicate with a main-body part is provided and a hole through and into which a wire material is passed and inserted is formed in the tube part. CONSTITUTION:A plurality of wire materials 7 are passed through holes 5 formed in the bottom part 4, they are guided into a main-body part 2 for a wire-harness assembling box 1, and the individual wire materials 8 are arranged nearly parallel inside a tube part 3. The tube part 3 is passed through a vehicle- body opening and protrudes inside a vehicle chamber. As a result, the individual wire materials 7 are guided into the vehicle chamber from an open end in the tube part 3 and they are connected to a prescribed terminal for an indoor connector 10 installed inside the vehicle chamber. The wire-harness assembling box 1 is fixed to a vehicle-body plate 12 by screwing a fixation lid 9. Thereby, wiring lines can be arranged in an assembled state, and the operating property of an assembly operation or the like is enhanced.

摘要： PURPOSE:To improve riding comfortableness and maneuvering stability by detecting a corresponding road surface state to each shock absorber so as to obtain a detection characteristic for each shock absorber, and individually correcting a reference value or a detection value in accordance with the characteristic. CONSTITUTION:Road surface state detecting means M2a-M2d provided corre sponding to respective shock absorbers M1a-M1d detect a road surface state to transmit to a damping force characteristic switching means M3 and to a correcting means M4. The correcting means M4 obtains detection characteristics of the respective detecting means M2a-M2d on the basis of the respective road surface state detection values, and individually corrects reference values or the road surface state detection values of the damping force characteristic switching means M3a-M3d in accordance with the detection characteristics. The switching means M3a-M3d compares the reference values and the detection values based on the results to change over individually the damping force characteristics of the respective shock absorbers M1a-M1d. According to this constitution, riding comfortableness as well as maneuvering stability is improved.

摘要： PURPOSE:To improve stability by switching a control carried out by means of a vibration condition control means from independent control for each wheel, into a control in which a pair of, left and right, wheels are synchronized, when acceleration and/or braking conditions of a vehicle are detected. CONSTITUTION:The vibration condition control means M3 of each wheel M2 changes characteristics such as damping force, spring constant, etc., of a vehicle supension device (shockabsorber) in compliance with the vibration condition detected by vibration condition detection means M1 and controls the vibration condition of a vehicle independently of each wheel M2 during traveling. Hereupon, when a traveling condition detection means M4 detects acceleration condition and/or braking condition of the vehicle, a left and right wheel synchronous control means M5 switches control carried out by means of the vibration condition control means M3 into control in which a pair of, left and right, wheels M2R, M2L are synchronized independently of each wheel M2. In this manner, characteristics of the damping force, the spring constant, etc., of the left and right wheels are generally equalized, so that driving force and braking force become equal in left and right wheels to be able to obtain good stability of the vehicle.

摘要： PURPOSE:To aim at miniaturizing the captioned electromagnetic flow regulating device as well as to make it possible to drive a plunger with low force, by eliminating fluid flow force exerted to the plungeer in the sliding direction thereof. CONSTITUTION:The first through holes 3a, 3b are provided at the center part of plungers 6, 7 along the axial direction thereof and the second through holes 3c, 3d for intercommunicating the first through holes 3a, 3b with the circumferential surface of the plunger are also provided. Further, the sliding direction of the plungers 6, 7 crosses rectangularly with the flow direction of fluid passing through the interior of the plungers 6, 7. Owing to this constitution, even if pressure becomes higher, fluid flow force which is exerted on the plungers 6, 7 in the sliding direction is not generated so that the plungers 6, 7 are operated with low force. And, it is possible to miniaturize said regulating device.

摘要： PURPOSE: To increase a stationary torque and an output torque even in a small size by providing a pair of stationary pole members opposed through an air gap to a rotor, and displacing obliquely the opposed ends of the members in a circumferential direction.
CONSTITUTION: A rotor 4 which has two surfaces parallel to a rotational shaft 7 and is made of a magnetic material is mounted on the shaft 7. A pair of arcuate stationary pole members 2, 3 are disposed through an air gap to the rotor 4 on the outer periphery of the rotor 4, and an exciting coil 1 for exciting the members 2, 3 is coupled. The positions of the opposed ends 2b and 3b, 2d and 3d of the members 2, 3 are displaced circumferentially, and the intermediate is inclined. Thus, output torque and detent torque are shared by the upper and lower portions of the rotor 4 to effectively generate the torques.

摘要： PURPOSE:To protect a tyre if it is punctured by increasing a ground clearance of a tyre which is placed in the lateral direction of the punctured tyre if the ground clearance of a tyre which is placed in the obliquely front or obliquely rear position of the punctured tyre is increased. CONSTITUTION:When a puncture detector 20 detects a puncture of a tyre, a puncture signal is sent to a receiving device 30. The receiving device then seeks for the punctured tyre from the front right, rear right, front left and rear right tyres 12, 14, 16 and 18. Suppose the front right tyre 12, for example, is punctured, the position of the tyre is input to a computer 32. The spring constant of the suspension unit of the punctured tyre is increased to restrain the punctured tyre from sink. The computer determines whether the ground clearance of the tyre 18 placed in the obliquely front or the obliquely rear position of the punctured tyre is increased or not. If the ground clearance is increased, the ground clearance of the tyre 16 which is placed in the lateral direction of the punctured tyre is increased. Such constitution can lessen a load which will be applied to the punctured tyre and protect the tyre.

摘要： PURPOSE: To make it possible to reach a vehicle height almost satisfying a target vehicle height as soon as possible, by closing a plurality of gas chambers, and supplying pressure gas to the gas chamber only with reduced capacity.
CONSTITUTION: Each of suspensions 12, 14, 16 and 18 is provided with two air chambers 20a and 20b. When both the air chambers 20a and 20b are communicated with each other, capacity of the air chambers becomes large to make a spring constant low. A vehicle height is detected by height sensors 22 and 23 provided at respective portions of a vehicle body opposite to left and right wheels, a height sensor 24 provided at an intermediate portion of the vehicle body between left and right rear wheels, and links 22a, 23a and 24a provided near the suspensions. When signals from the sensors are input to CPU26, and vehicle height is lower than a predetermined height, the computer 26 acts to drive a motor 28 to operate an air compressor 30, and also open leveling valves 32. Further, the computer 26 acts to operate actuators 34 to temporarily close the air chambers 20a and 20b.
