    • A steering device for a two-wheeler of the present invention includes: a frame; a support member for a front wheel; a steering shaft connecting the support member to the frame so as to be rotatable about an axis thereof; and a rotary type steering damper providing a hydraulic resistance force in no matter which direction the support member rotates with respect to the frame. The steering damper has a vane adapted to swing in synchronism with rotation of the support member, oil chambers defined on both sides of the vane and filled with working fluid, a flow passage causing working fluid to flow from one oil chamber to the other oil chamber as the vane swings, and a damping valve arranged in a flow passage for the working fluid, and an opening of the damping valve is varied by a signal from outside to thereby generate a damping force optimized according to the travel condition.
    • 本发明的二轮转向装置包括:框架; 用于前轮的支撑件; 转向轴,其将所述支撑构件连接到所述框架,以便能够绕其轴线旋转; 以及无论支撑构件相对于框架旋转的哪个方向,提供液压阻力的旋转式转向阻尼器。 转向阻尼器具有叶片,该叶片适于与支撑构件的旋转同步地旋转,限定在叶片两侧的油室充满工作流体,流动通道使得工作流体从一个油室流动到另一个油室 当叶片摆动时,设置在用于工作流体的流动通道中的阻尼阀,并且阻尼阀的开口由来自外部的信号变化,从而产生根据行驶条件优化的阻尼力。
