    • A rear suspension system for a bicycle. The system directs the rear wheel along a predetermined, S-shaped path as the suspension is compressed. The path is configured to provide a chainstay lengthening effect only at those points where this is needed to counterbalance the pedal inputs of the rider; at those points in the wheel travel path where there is a chainstay lengthening effect, the chain tension which results from the pedal inputs exerts a downward force on the rear wheel, preventing unwanted compression of the suspension. The system employs a dual eccentric crank mechanism mounted adjacent the bottom bracket shell to provide the desired control characteristics.
    • 一种用于自行车的后悬挂系统。 当悬架被压缩时,系统沿着预定的S形路径引导后轮。 该路径被配置为仅在需要这些点的情况下提供链条延长效果来抵消骑手的踏板输入; 在具有链条延长效果的车轮行进路径中的那些点处,由踏板输入引起的链条张力在后轮上施加向下的力,防止悬架的不必要的压缩。 该系统采用安装在底托架壳体附近的双偏心曲柄机构,以提供所需的控制特性。
