Abstract
In a steering damper utilizing hydraulic pressure, even if generation of a damping force is controlled in correspondence with an external force inputted to a handle upon external perturbations and the like, the damping force changes due to change in liquid temperature of working liquid. Accordingly, to precisely control the damping force, correction based on change in liquid temperature of the working liquid is required. However, to measure the change in liquid temperature of the working liquid, it is necessary to provide a particular measurement device requiring a complicated structure, which increases the number of parts and costs. Accordingly, the present invention has an object to provide a steering damper which can easily temperature-correct the damping force without such difficulty. A liquid chamber is provided in a main body of a steering damper. An inside of the liquid chamber is partitioned into a right liquid chamber and a left liquid chamber by a rotatable partition wall integral with a shaft coaxial with a steering shaft. Both liquid chambers are connected with each other by a liquid passage, and a control valve is provided in the middle of the passage such that the damping force is variable. A control device drive-controls the control valve in correspondence with a turning angle speed of the shaft and the partition wall, thereby controls the damping force, and corrects the damping force based on intake temperature information detected by an intake temperature sensor.
