摘要： PROBLEM TO BE SOLVED: To provide damper fitting structure reduced in the sorts of parts so as to facilitate damper fitting work without being influenced by dimensional dispersion even in the case of the occurrence of the dimensional dispersion between the damper fitting parts of a body frame and an axle. SOLUTION: A fitting piece 14 is integrally formed at the body 12a of a damper 12, and a through hole 14a is formed in the fitting piece 14. The body 12a is fixed to the fitting face 13a of a body frame body thread-fastening a screw 15 into a threaded hole 13b formed in the fitting face 13a, through the through hole 14a of the fitting piece 14. A roller 17 is rotatably supported to the tip of a piston rod 12c of the damper 12. The outer peripheral surface 17a of the roller 17 comes in contact with the upper face 11a of a rear axle 11, and the roller 17 rolls so as to follow the oscillation of the rear axle 11.

摘要： PROBLEM TO BE SOLVED: To prevent damage to a damper by an excessive load without enlarging the damper. SOLUTION: A damper 12 is arranged between a body frame 1a and a rear accelerator 11 to supply and discharge a hydraulic fluid according to the rocking of the rear accelerator 11. A controller C controls the damper 12 so as to lock it as occasion demands and fix the rear accelerator 11 to the body frame 1a. A shut-off valve 13 switches each piping P1-P3 for carrying the hydraulic fluid supplied and discharged from the damper 12 to interrupted state and communicating state according to the control of the controller C. When the hydraulic pressure within the damper 12 reaches a relief pressure in the state where the pipings P1-P3 are laid in the interrupted state by the shut-off valve 13, first and second valves 19, 20 reduce the pressure so that this hydraulic pressure does not exceed the maximum resistant hydraulic pressure of the damper.

摘要： PROBLEM TO BE SOLVED: To reduce more regulation of the rocking of an axle than required in a device regulating the rocking of an axle in accordance with the height of the center of gravity of a vehicle. SOLUTION: A rear axle 10 carrying rear wheels 11 is provided as to allow it to pivot on a center pin 10a against a body frame, and connected at its end to the body frame via a damper 13. A controller 25 uses the values θ and V detected respectively by a wheel angle sensor 21 and a vehicle speed sensor 22 to calculate the lateral gravity applied to a vehicle body, and switches over a solenoid operated selector valve 14 to lock the damper 13 when the lateral gravity exceeds the specified value. The specified value for the lateral gravity G is so determined, from the lift H detected by a lift sensor 23 and the load W detected by a pressure sensor 24, as to correspond step by step to the height of the center of gravity of vehicles, using a map.

摘要： PROBLEM TO BE SOLVED: To almost positively find a failure of a detector provided in a vehicle in order to obtain a criterion value for use in regulating and controlling oscillation of an axle. SOLUTION: In the control device, when either of lateral G and the rate ΔY of change of yaw rate of a vehicle, calculated using the respective detected values θ, V of a tire angle sensor 21 and a car-speed sensor 22, is above a set value, a controller 28 shuts off a solenoid change-over valve 14 of a damper 13 to lock a rear axle 10 swingably mounted on car-body frame. Further, the controller 28 makes failure-diagnosis of the tire angle sensor 21. The correspondence-relations between the tire angular speed Δθ and the handle angular speed ΔH calculated based on the respective detected values θ, h of the tire angle sensor 21 and a handle angle sensor 25 are compared with each other, and when ΔH>0 and Δθ=0 are established, the tire angle sensor 21 is judged to be failed out. Furthermore, when a detected value (input voltage) θis outside the range of detected values at normal times, the tire angle sensor 21 is judged to be a failure of disconnection or short circuit.

摘要： PROBLEM TO BE SOLVED: To ensure easy and stable release of fixation of axle. SOLUTION: To a vehicle body frame 1a of a forklift truck a rear axle 11 is connected to be swingable around a center pin 11a and on both ends a rear wheel 8 serving as a steered wheel. Between the axle 11 and the frame 1a a damper 12 is connected which is connected to a reservoir 16 through an electromagnetic proportional valve 13. When a stationary operation signal is output from a controller, the valve 13 is turned into a full closed condition to lock the damper 12 and fix the axle 11. When the output is released from the condition, the valve 13 is gradually opened according to the release. Accordingly the fixation of the axle 11 is released gradually at a specified speed and thereby the fixation of axle 11 can be released under a stable condition.

摘要： PROBLEM TO BE SOLVED: To turn an industrial vehicle speedily and in a stabler state. SOLUTION: A rear axle 11 is connected to a car body frame 1a of a forklift free to oscillate around a center pin 11a as its center, and rear wheels 8 as steering wheels are connected to its both ends. A damper 12 is connected between the rear axle 11 and the car body frame 1a, and the damper 12 is connected to a reservoir 16 through a solenoid valve 13. The solenoid valve 13 locks the damper 12 and fixes the rear axle 11 when a fixed motion signal is output from a controller. Additionally, when the fixed motion signal is not output, it unlocks the damper 12 and makes the rear axle 11 in a state free to oscillate. In this case, the controller computes a yaw rate changing ratio in accordance with a detection signal from a gyroscope to detect a yaw rate working on the relative vehicle and outputs the fixed motion signal at the time when the change rate becomes larger than a standard value.

摘要： PROBLEM TO BE SOLVED: To provide an elevatable cylinder with damper of which the length in the axial direction is relatively short although the elevatable cylinder is integrated with the damper. SOLUTION: An elevatable cylinder 50 moves a wheel up and down in the leg device of a magnetic levitation vehicle and the like. A second cylinder member 150 is provided on the outer circumference of the cylinder main body 52 of such elevatable cylinder 50 concentrically to the cylinder main body 52. Oil chambers are partitioned off between the outer circumference of the cylinder main body 52 and the second cylinder member 150, and a damper 80 is constituted utilizing the oil chambers. The damper 80 functions so as to cushion variation of a load applied to the elevatable cylinder 50 in the axial direction. By this constitution, because the part of the damper 80 is included in the length of the cylinder main body in the axial direction, although this is an elevatable cylinder with damper 30, the length is equal to the length of the elevatable cylinder itself.
