As shown in fig. 2, as one implementation, a rear suspension 132 is disposed on a rear side of the frame 11 and connects the frame 11. The rear suspension 132 includes a rear rocker arm 1321, a rear shock absorber 1322, a knuckle 1323, and a link assembly 1324. One end of the rear rocker arm 1321 is connected to the vehicle frame 11, and the other end of the rear rocker arm 1321 is connected to the knuckle 1323. One end of the rear shock absorber 1322 is connected to the frame 11, and the other end of the rear shock absorber 1322 is connected to the rear swing arm 1321.

Specifically, the knuckle 1323 includes a first mounting point 1323a, a second mounting point 1323b, and a third mounting point 1323 c. First mounting point 1323a is disposed forward of second mounting point 1323b, first mounting point 1323a is also disposed forward of third mounting point 1323c, and second mounting point 1323b is disposed upward of third mounting point 1323c, in the forward-rearward and upward-downward directions of atv 100.

By the arrangement, the fixed points of the walking assembly 12 and the frame 11 can be increased through the first connecting rod 1324a, the second connecting rod 1324b and the third connecting rod 1324c, so that the wheel track change of the walking assembly 12, namely the positioning parameters of the walking assembly 12 are controlled, and the operation stability and the driving safety of the all-terrain vehicle 100 are improved. In addition, the first link 1324a, the second link 1324b and the third link 1324c can form a fixed frame of the walking assembly 12, so that the suspension assembly 13 can be precisely controlled, and the safety of the all-terrain vehicle 100 can be improved. In this embodiment, since both ends of the first link 1324a are rotatably connected, both ends of the second link 1324b are rotatably connected, and both ends of the third link 1324c are rotatably connected, the track width of the traveling assembly 12 can be controlled without affecting the damping effect of the traveling assembly 12, that is, without affecting the damping effect of the rear rocker arm 1321 and the rear shock absorber 1322 on the all-terrain vehicle 100, thereby improving the stability of the all-terrain vehicle 100.
