In one aspect, there is provided an isolation device, which includes a hub, a pulley and at least one isolation spring arrangement including first and second springs in series. The first spring rate is higher than the second spring rate. Initially during torque transfer from the first one to a second one of the hub and the pulley, the entire first isolation spring is slid along a friction surface towards the second one of the hub and the pulley during compression of the second isolation spring thereby generating a first frictional damping torque. During torque transfer the other way, at least a portion of the first isolation spring remains stationary relative to the friction surface, such that the first frictional damping torque is greater than the second frictional damping torque.
在一方面中,提供了一种隔离装置,该隔离装置包括轮毂、带轮和至少一个隔离弹簧装置,所述至少一个隔离弹簧装置包括串联的第一弹簧和第二弹簧。第一弹簧刚度大于第二弹簧刚度。在从轮毂和带轮中的第一者至第二者的扭矩传递期间开始,整个第一隔离弹簧在第二隔离弹簧的压缩期间沿着摩擦表面朝向轮毂和带轮中的第二者滑动,从而产生第一摩擦阻尼扭矩。在另一种方式的扭矩传递期间,第一隔离弹簧的至少一部分相对于摩擦表面保持静止,使得第一摩擦阻尼扭矩大于第二摩擦阻尼扭矩。
