| 摘要 | An impact absorbing mechanism for a wheel is provided. The mechanism has discs that are engaged so that rotation of a first disc causes translational movement of a second disc. A restraining member such as a spring acts against translational movement of the second disc to absorb energy from a head on collision or aggressive braking. Once the mechanism is fully activated, teeth on the first and second discs engage to prevent kick back from the restraining member. In some embodiments, a ratchet mechanism is provided to prevent kick back from the restraining member even when the impact absorbing mechanism is not fully activated. | ||||||
