A tracked vehicle is provided. The tracked vehicle includes a frame, a driving mechanism installed in the frame, and two track wheels respectively arranged on the left and right sides of the frame. The driving mechanism drives the track wheels to rotate. The track wheel includes a track body, a first main support, a second main support and a third main support provided in the track body. The first main support, the second main support and the third main support are connected to the vehicle frame through the first, second and third connecting rods respectively. The second main support is provided with an auxiliary support frame having one end hinged to the second main support, and the other end of the auxiliary support frame is provided with a first roller contacting with the inner side of the track body.

The invention relates to a double-sided drilling fixture for die-forged pistons and a double-sided drilling process thereof. It overcomes the defects of low efficiency and accuracy of the double-sided drilling operation for die-forged pistons in the prior art. The invention comprises a die-forged piston, a fixture base assembly, an upper load-resisting assembly and a lower expansion-resisting assembly. The upper load-resisting assembly is installed on the fixture base assembly and disposed above the die-forged piston. A fixation base, whose upper surface shape is the same as internal surface shape of the die-forged piston, is installed above the fixture base assembly. The die-forged piston is sleeved on the fixation base. The invention achieves simultaneous drilling on both sides of the two rear skirt surfaces of die-forged pistons and delivers quick clamping and automatic fixation, significantly reducing the difficulty in the assembly of drilling plate and workpiece and increasing the alignment accuracy.
