Claim 0:
1. An axle of a vehicle, comprising:
a driving gear;
a driven disc comprising a driven gear meshing with the driving gear, the driven disc being hollow inside, an inner peripheral surface of the driven disc being a first contact surface, and a planetary driving gear being arranged in the driven disc;
two half shaft connectors arranged inside the driven disc and spaced apart in an axial direction, each of the half shaft connectors comprising a planetary driven gear, the two planetary driven gears meshing with the planetary driving gear on two sides of the planetary driving gear, and an outer periphery of one of the half shaft connectors comprising a second contact surface, wherein one of the first contact surface and the second contact surface is an annular surface, and the other one of the first contact surface and the second contact surface is a polygonal surface formed by a plurality of faces connected sequentially; and
a differential lock device comprising a plurality of rolling members, a rolling holder, a switching driving member, a switching driven member, and a second elastic reset mechanism,
wherein the plurality of rolling members are arranged in the rolling holder and in one-to-one correspondence with the plurality of faces of the polygonal surface, and the plurality of rolling members are movable along the corresponding faces to define a disengaged position and an engaged position relative to the annular surface;
the driven disc rotates relative to one of the half shaft connectors when the rolling members are in the disengaged position, and the driven disc and the one of the half shaft connectors rotate synchronously when the rolling members are in the engaged position;
the switching driven member is arranged on the rolling holder, the switching driving member selectively drives the switching driven member to move the rolling holder, and the rolling members move from the disengaged position to the engaged position;
the second elastic reset mechanism returns the rolling members from the engaged position to the disengaged position;
the switching driven member comprises a main body, and a plurality of cutting portions being formed on an outer periphery of the main body and stirring air when the switching driven member rotates;
the second elastic reset mechanism comprises a second elastic member and a second limit member, the second limit member is fitted on an inner periphery of the rolling holder and rotates synchronously with the rolling holder, the second elastic member is fitted over one of the half shaft connectors, and two ends of the second elastic member are fitted on the second limit member and the one half shaft connector correspondingly.
