The invention discloses a two-gear four-wheel-drive transfer case system and a vehicle. The two-gear four-wheel-drive transfer case system comprises a driving wheel, two driven wheels, a first-gear clutch, a second-gear clutch, a first-gear driving gear and a second-gear driving gear, wherein pushing pieces are arranged on the two side faces of the driving wheel in the axial direction. The two driven wheels are respectively arranged on two sides of the driving wheel. Arc-shaped grooves are formed in the driven wheels, the pushing pieces are matched in the arc-shaped grooves, at least part of the groove bottoms of the arc-shaped grooves have gradients, and the directions of the gradients of the groove bottoms of the arc-shaped grooves in the two driven wheels are opposite. The first-gear clutch and the second-gear clutch are arranged on the sides, away from the driving wheel, of the two driven wheels correspondingly. The first-gear driving gear is connected with the first-gear clutch and matched with the first-gear driven gear, the second-gear driving gear is connected with the second-gear clutch and matched with the second-gear driven gear, and when the clutches are compressed, the corresponding driving gear can transmit torque to the corresponding driven gear. The driving wheel rotates forwards and backwards to extrude the driven wheels on the different sides respectively, then the clutch on the side is extruded, switching of the first gear and the second gear is achieved, the structure is simple, switching is convenient and fast, and cost is lower.

    本发明公开了一种两挡四驱分动器系统及车辆。两挡四驱分动器系统包括:主动轮,其沿轴向的两个侧面均设有推动件;两个从动轮,分别设于主动轮的两侧;从动轮上设置有弧形槽,推动件配合在弧形槽中,弧形槽的槽底至少部分具有坡度,两个从动轮上的弧形槽槽底的坡度方向相反;一挡离合器及二挡离合器,分别设于两个从动轮的远离主动轮的一侧;一挡主动齿轮,与一挡离合器连接且与一挡从动齿轮配合,二挡主动齿轮,与二挡离合器连接且与二挡从动齿轮配合,当离合器被压紧时对应的主动齿轮能向相应的从动齿轮传递扭矩;主动轮正转和反转可分别挤压不同侧的从动轮,进而挤压该侧的离合器,实现一挡和二挡的切换,结构简单,切换便捷,成本较低。
