The invention discloses a small-curve expansion joint for a side contact rail system, and relates to the technical field of urban power rails. The small-curve expansion joint comprises a fixed rail, asliding rail and a fishtail guide clamping plate, the fishtail guide clamping plate is arranged in rail webs of the fixed rail and the sliding rail, ends of the fixed rail and the sliding rail are incontact with each other, and a rolling structure is arranged on an end contact surface of the fixed rail and/or the sliding rail parallel to the length direction of the rail. The rolling structures are arranged on the contact surfaces of two sliding blocks, so that the contact surfaces of the sliding rail and the fixed rail are in elastic contact all the time, the two sliding rails support each other, and deflection deformation under the action of gravity is effectively prevented.

    一种侧接触轨系统用小曲线膨胀接头,涉及城市电力轨道技术领域,包括固定轨,滑动轨,鱼尾导向夹板,所述鱼尾导向夹板设置于固定轨和滑动轨的轨腰中,所述固定轨和滑动轨的端部相互接触,在与轨道长度方向平行的固定轨和/或滑动轨的端部接触面上,设置有滚动结构。通过在两个滑块的接触面上设置有滚动结构,使得滑动轨和固定轨的接触面之间始终弹性接触,两个滑轨之间相互支撑,有效防止重力作用下的扰度变形。
