The invention discloses a two-gear speed reducer and a vehicle applying the same. The two-gear speed reducer comprises a motor rotor (1), a planetary gear mechanism (2), a first-stage transmission mechanism (3), a second-stage transmission mechanism (4) and a differential mechanism (5), the motor rotor (1) is connected with the planetary gear mechanism (2); the planetary gear mechanism (2) is fixedly connected with the primary transmission mechanism (3); the first-stage transmission mechanism (3) is meshed with the second-stage transmission mechanism (4), and the second-stage transmission mechanism (4) is meshed with a first gear ring (51) of the differential mechanism (5); wherein the differential mechanism (5) is coaxial with the motor rotor (1). The two-gear speed reducer is more compact in structural layout and small in occupied space.

    一种两档减速器及应用其的车辆,两档减速器包括电机转子(1)、行星齿轮机构(2)、一级传动机构(3)、二级传动机构(4)和差速器(5);电机转子(1)与行星齿轮机构(2)连接;行星齿轮机构(2)与一级传动机构(3)固定连接;一级传动机构(3)与二级传动机构(4)啮合,二级传动机构(4)与差速器(5)的第一齿圈(51)啮合;其中,差速器(5)与电机转子(1)同轴。两档减速器的结构布局更加紧凑、占用空间小。
