The invention provides a semi-independent suspension with inclined leaf springs and belongs to the field of automobile engineering. The suspension comprises a frame, a half axle, and two semi-independent suspension devices on the two sides of the frame; the suspension device on each side comprises four inclined leaf springs; the first and fourth inclined leaf springs are symmetrical about the half axle, while the second and third inclined leaf springs are symmetrical about the half axle; the line of intersection of longitudinal symmetrical central planes determined by the first and fourth inclined leaf springs is parallel to or collinear to the line of intersection of longitudinal symmetrical central planes determined by the second and third inclined leaf springs. According to the semi-independent suspension, the wheels on the left and right two sides are directly connected without a hard shaft, and therefore, the semi-independent suspension is better than a traditional non-independent leaf spring suspension in manipulation stability and driving smoothness. Meanwhile, four leaf springs connected in parallel are capable of effectively bearing and alleviating impact to achieve better bearing capability and reliability; in addition, the distance between the bearing centers on the two sides and the steering range of the wheels are increased, and therefore, the whole vehicle is enabled to be better in low-speed flexibility.
