摘要: Providing a damper which exerts a damping force in an entire stroke range and an overturn preventing device which can successfully prevent an article from overturn by equipment of the damper. The damper includes a cylinder, a rod guide, a piston, a rod, and a cylindrical member. In the damper, a hydraulic fluid and a compressed gas are enclosed in the cylinder. The cylindrical member regulates a position of the piston so that the piston is immersed in the hydraulic fluid enclosed below the gas in a state where a bottom of the cylinder is located lower than an opening and the rod protrudes upward from the cylinder and where central axes of the cylinder and the rod are inclined at a predetermined angle with respect to a horizontal plane.

摘要: A sensor appropriately detects the state of a fluid while reducing the effects of fluid temperature on fluid characteristics. The sensor includes a characteristics acquisition unit, a temperature measurement unit, a storage unit, and a correction unit. The characteristics acquisition unit acquires a characteristic value for an in-device fluid. The temperature measurement unit measures the in-device fluid temperature when the characteristics acquisition unit acquires the characteristic value. The storage unit stores a database registering an association between a pre-acquired characteristic of the in-device fluid and the in-device fluid temperature measured when the characteristic of the in-device fluid was pre-acquired. The correction unit corrects the characteristic value of the in-device fluid acquired by the characteristics acquisition unit based on the in-device fluid temperature measured by the temperature measurement unit and the database.

摘要: A damper control device includes a rate sensor that detects a pitching angular velocity of a vehicle body, a vehicle speed sensor, a steering angle sensor and a calculation unit that detect a roll angle and a yaw angular velocity of the vehicle body, a pressure sensor that detects a pressure of a contraction-side chamber in a front-wheel side damper, a pressure sensor that detects a pressure of a contraction-side chamber in a rear-wheel side damper, and a correction unit that corrects the pitching angular velocity. The pressures are controlled on the basis of the corrected pitching angular velocity and the pressures. The vehicle speed sensor, the steering angle sensor and the calculation unit detect the roll angle and the yaw angular velocity on the basis of a traveling speed and a steering angle.
