The invention relates to a combined pawl speed changer. The combined pawl speed changer comprises a power input piece, a center shaft, a hub, a first automatic gear shifting mechanism, a second automatic gear shifting mechanism, a first planet speed changing mechanism, a second planet speed changing mechanism, a first overrunning clutch and a second overrunning clutch. The first automatic gear shifting mechanism comprises a first pawl piece frame, a first ratchet wheel, a second ratchet wheel, a first pawl piece, a first balance weight piece, a linkage pawl piece and a first balance weight piece. The first balance weight piece is in linkage connection with the linkage pawl piece. A first pawl part is arranged on the first pawl piece; a second pawl part is arranged on the linkage pawl piece; the first pawl part and the first ratchet wheel form a first meshing pair, the second pawl part and the second ratchet wheel form a second meshing pair, and when one of the first meshing pair and the second meshing pair is meshed, the other one is disengaged, so that the speed ratio between a low-speed gear and a medium-speed gear of the speed changer is more reasonable, and riding is easier.

    本发明涉及一种联合棘爪变速器,包括:动力输入件、中心轴、轮毂、第一自动换挡机构、第二自动换挡机构、第一行星变速机构、第二行星变速机构、第一超越离合器及第二超越离合器,所述第一自动换挡机构包括:第一棘爪件架、第一棘轮、第二棘轮、第一棘爪件、第一配重件、联动棘爪件及第一平衡件,所述第一配重件与联动棘爪件之间联动连接,所述第一棘爪件上设有第一棘爪部,所述联动棘爪件上设有第二棘爪部,所述第一棘爪部与第一棘轮组成第一啮合副,所述第二棘爪部与第二棘轮组成第二啮合副,所述第一啮合副与第二啮合副两者中,其中一者啮合时,另一者脱离啮合,从而使变速器低速挡与中速挡之间的速比更加合理,骑行更加轻松。
