这种旁承使用受剪切力和压缩力的橡胶装置,取得所需要的纵向阻力和垂直承载能力,以消除轮绿在它和钢轨之间的间隙中的搖摆运动。上下旁承间由于垂直载荷所发生的摩擦力,要能够在转向架倾斜到它的对角车轮的轮绿和钢轨间沒有间隙时就开始滑
This sideshield uses a rubber device that is subjected to shear and compressive forces to achieve the desired longitudinal resistance and vertical load carrying capacity to eliminate the swinging motion of the wheel green in the gap between it and the rail. The friction between the upper and lower side bearers due to vertical loads should be able to start sliding when the bogie is tilted until the wheels of its diagonally opposite wheels and rails have no gap
