Abstract: A dual-rate jounce bumper limits jounce travel between a first component and a second component of a vehicle. The second component is spaced from and moveable toward the first component along a jounce axis. The dual-rate jounce bumper includes a bumper and an outer member. The bumper has a first end for coupling to the first component and a second end spaced from the first end for contacting the second component as the second component moves along the jounce axis toward the first component. The bumper is compressible between the first and second components for limiting jounce travel. The bumper is also radially expandable as the bumper is compressed. The outer member is disposed about the bumper and is capable of limiting the radial expansion of the bumper as the bumper is compressed for increasing a stiffness of the bumper.

Abstract translation: 双速率跳闸保险杠限制车辆的第一部件和第二部件之间的跳动。 第二部件沿着柔顺轴线与第一部件间隔开并可向第一部件移动。 双速率跳闸保险杠包括保险杠和外部构件。 保险杠具有用于联接到第一部件的第一端和与第一部分间隔开的第二端，用于当第二部件沿着柔顺轴线朝向第一部件移动时接触第二部件。 保险杠在第一和第二部件之间是可压缩的，用于限制行程。 当保险杠被压缩时，保险杠也可径向扩展。 外部构件围绕保险杠设置，并且当缓冲器被压缩时能够限制保险杠的径向膨胀，以增加保险杠的刚度。
