The invention discloses a pure mechanical automatic speed changing device which comprises a first-stage input shaft assembly, a second-stage shaft assembly and a differential mechanism, the first-stage input shaft assembly is connected with the second-stage shaft assembly in a meshed mode, the second-stage shaft assembly is connected with the differential mechanism in a meshed mode, the first-stage input shaft assembly is used for achieving gear shifting, and the second-stage input shaft assembly is used for achieving gear shifting. The second-stage shaft assembly is used for achieving non-interference of high-gear power transmission, low-gear power transmission and reverse-gear power transmission. Any (reasonably required) vehicle speed upshift and any (reasonably required) vehicle speed downshift can be set; when used in a speed control system, the gear shifting mechanism can realize active gear shifting; the service life is long, and the torque is transmitted without centrifugal friction, so that friction loss is avoided; the automatic gearbox body is simple and compact in overall structure and small in size; out-of-gear is avoided; the design values of the upshift state and the downshift state are different, so that the condition of repeated upshift and downshift is avoided; wherein the clutch can realize high-torque transmission torque; and an electric control automatic gear shifting system can be mainly replaced.

    本发明公开了一种纯机械自动变速装置,包括一级输入轴总成、二级轴总成和差速器,所述一级输入轴总成与二级轴总成啮合连接,所述二级轴总成与差速器啮合连接,所述一级输入轴总成用于实现档位的切换,所述二级轴总成用于实现高、低、倒档位动力传递不干涉;能够在设定任意(合理需要的)车速升档,任意(合理需要的)车速降档;用于变速系统中,能够实现主动变档;使用寿命长,不依靠离心摩擦传递扭矩,故没有摩擦损耗;自动变速箱体总体结构简单、紧凑、体积小;不会脱档;升档状态与降状态设计值不同,不会出现反复升降档的情况;其中的离合器能够实现高扭矩传递力矩;主要的可替代电控自动变档系统。
