1. An all-terrain vehicle, comprising:
a frame;
a transmission mounted on the frame;
an axle support;
a driving shaft coupled between the transmission and the axle support; and
a rear suspension assembly comprising a left rear suspension subassembly and a right rear suspension subassembly symmetrically arranged at left and right sides of the frame, each of the left rear suspension subassembly and the right rear suspension subassembly comprising an upper control arm and a lower control arm, the upper control arm having a first end pivotally coupled to the frame and a second end pivotally coupled to the axle support, the lower control arm having a first end pivotally coupled to the frame and a second end pivotally coupled to the axle support, a junction of the first end of the upper control arm and the frame being located behind the driving shaft, the first end of the upper control arm being pivotally coupled to the frame by a single first upper pivot;
an included angle between a plane determined by the first upper pivot and a first lower front pivot or a first lower rear pivot and a longitudinal central symmetry plane of the all-terrain vehicle is α, and the α is greater than or equal to 2.5 degrees and less than or equal to 10 degrees;
the second end of the upper control arm is pivotally coupled to the axle support by a second upper pivot, the second upper pivot is parallel to the longitudinal central symmetry plane of the all-terrain vehicle, a distance between the second upper pivot and the longitudinal central symmetry plane of the all-terrain vehicle is C, a distance between a second lower front pivot or a second lower rear pivot and the longitudinal central symmetry plane of the all-terrain vehicle is D, and C is less than D.
