The invention discloses a device for multi-angle loading of an undercarriage. The device comprises a wheel shaft fixing part, a movable loading plate and a fixed loading plate, wherein an open hole isformed in the middle of the movable loading plate, the wheel shaft fixing part penetrates through the open hole and is connected with the movable loading plate, and the movable loading plate freely rotates around the wheel shaft fixing part through the open hole; the fixed loading plate comprises a first plate and a second plate, the first plate and the second plate are both fixed on the wheel shaft fixing part, a gap is reserved between the first plate and the second plate, the movable loading plate is fixed in the gap, and the fixed loading plate limits the movable loading plate at the wheel center position corresponding to the wheel shaft fixing part; the movable loading plate is provided with a wheel center loading hole, and the fixed loading plate is provided with a grounding point loading hole. According to the device for multi-angle loading of the undercarriage, variable-stroke loading of an undercarriage fatigue test is achieved, and in the two state conversion processes of the test, the device is automatically adjusted to the corresponding loading position to load a test piece.
