    • A belt tensioner (10) of the Zed type with a base member (24), a pivot-arm (28), a pivot-pin (22), a pulley (12) attached to the pivot-arm (28), a torsional spring (26) attached between the base member (24) and pulley (12), and wherein the base member (24) has a "tube pan" shape with a cantilevered inner wall (32) that supports the pivot-pin (22), a cantilevered outer wall (36), and a bottom wall (38) interconnecting the inner and outer walls and oriented with the bottom wall (38) juxtaposed the pivot-arm (28). Optionally, the spring (26) connected to a damping mechanism (94,96,98) that generates a reaction force in generally the same direction as a belt force or hub load. In another embodiment, a second, damping spring generates a reaction force in generally the same direction as the belt force and a constant damping force.
    • 具有基座构件(24),枢转臂(28),枢轴销(22),附接到枢转臂(28)的滑轮(12))的扎带类型的皮带张紧器(10) 扭转弹簧(26),其安装在基部构件(24)和滑轮(12)之间,并且其中基部构件(24)具有“管盘”形状,其具有支撑枢轴销(22)的悬臂内壁(32) ),悬臂外壁(36)和互连内壁和外壁的底壁(38),并且底壁(38)与枢转臂(28)并置。 可选地,弹簧(26)连接到阻尼机构(94,96,98),其产生与带力或轮毂负载大致相同方向的反作用力。 在另一个实施例中,第二阻尼弹簧产生与带力大致相同方向的反作用力和恒定的阻尼力。
