STEERING DAMPER APPARATUS

摘要

In a steering damper utilizing hydraulic pressure, even if generation of damping force is controlled in correspondence with 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 particular measurement means 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 26 is provided in a main body 17 of a steering damper 10, and its inside is partitioned into a right liquid chamber 27 and a left liquid chamber 28 by a rotatable partition wall 30 integral with a shaft 23 coaxial with a steering shaft 14. The both liquid chambers are connected with each other by a liquid passage 33, and a control valve 31 is provided in the middle of the passage such that the damping force is variable. A control device 32 drive-controls the control valve 31 in correspondence with a turningangle speed of the shaft 23 and the partition wall 30, thereby controls the damping force, and corrects the damping force based on intake temperature information detected by an intake temperature sensor 34.
