The invention relates to the field of vehicles, and discloses a variable-speed transmission device and a vehicle provided with the variable-speed transmission device, the variable-speed transmission device comprises a transmission shell (K1), a main variable-speed gear set (3), an auxiliary variable-speed gear set (4), a rear axle driving shaft (51) and a front axle driving shaft (52), the transmission shell (K1) is provided with a front supporting wall (B1), a middle supporting wall (B2) and a rear supporting wall (B3) located at the rear end, the front axle drive shaft (52) is pivotally mounted to the rear support wall (B3) to leave a space for arranging a change gear and a transmission gear on the rear axle drive shaft (51). The variable-speed transmission device can avoid occupying the space of a second chamber (S2) between the middle supporting wall and the rear supporting wall, so that a space for arranging a low-speed driven gear, a front axle driving shaft driving gear and the like can be reserved in the second chamber, and the limitation of the supporting walls on arrangement and installation of a variable-speed gear and a transmission gear is effectively reduced.

    本发明涉及车辆领域,公开了一种变速传动装置及设有其的车辆,所述变速传动装置包括变速器壳体(K1)、主变速齿轮组(3)、副变速齿轮组(4)以及后桥驱动轴(51)和前桥驱动轴(52),所述变速器壳体(K1)设有前支撑壁(B1)、中间支撑壁(B2)和位于后端的后支撑壁(B3),所述前桥驱动轴(52)枢转安装至该后支撑壁(B3)以留出布置所述后桥驱动轴(51)上的变速齿轮和传动齿轮的空间。该变速传动装置可以避免占用中间支撑壁与后支撑壁之间的第二室(S2)的空间,由此可以在该第二室中留出布置低速从动齿轮和前桥驱动轴主动齿轮等的空间,有效降低支撑壁对变速齿轮和传动齿轮的布置和安装的限制。
