The invention provides an automatic transmission, and belongs to the technical field of speed change. The problems that buffering is unstable, and the buffering effect is poor are solved. The automatic transmission comprises an input shaft, an output shaft, an outer cover and a rotating part, the output shaft is parallel to the input shaft, the outer cover is in linkage with the output shaft, the rotating part can be in linkage with the input shaft when the rotating speed of the input shaft is increased, a reduction gear pair is arranged between the input shaft and the output shaft, and the output shaft can be separated from the reduction gear pair when the rotating speed of the output shaft is increased. The rotating part is partially located in the outer cover, a friction block is arranged between the rotating part and the outer cover, the rotating part can drive the friction block to rotate when rotating, and an elastic part which acts on the friction block to make the friction block make contact with the inner circumferential wall of the outer cover to form friction force is further arranged in the outer cover. The automatic transmission has the advantages of good buffering effect, more stable buffering, long service life and the like.

    本发明提供了自动变速器,属于变速技术领域。它解决了缓冲不稳定、缓冲效果不佳的问题。它包括输入轴、与输入轴平行的输出轴、与输出轴形成联动关系的外盖以及当输入轴转速增大时能与其联动的旋转件,输入轴与输出轴之间设有减速齿轮副且当输出轴转速增大时能与减速齿轮副相脱开,旋转件部分位于外盖内且在两者之间设有摩擦块,当旋转件转动时能带动摩擦块转动,外盖内还设有作用在摩擦块上使其与外盖内周壁相接触形成摩擦力的弹性件。它具有缓冲效果好、缓冲更加稳定、使用寿命长等优点。
