Abstract

The utility model discloses a suspension multi-axis test wheel end loading system, comprising a wheel end connecting mechanism comprising a special-shaped connecting plate; the vertical loading mechanism comprises a U-shaped frame, the upper portion of the special-shaped connecting plate is embedded into the inner side of the U-shaped frame, and the two ends of the U-shaped frame are connected with the two ends of the special-shaped connecting plate through spherical hinges; the longitudinal loading mechanism is connected with one end of the U-shaped frame through a spherical hinge; and the lateral loading mechanism is connected with the lower part of the special-shaped connecting plate through a spherical hinge. According to the suspension multi-axis test wheel end loading system, loads in the vertical direction, the lateral direction and the longitudinal direction can be completely and independently loaded on the wheel center point of a suspension system, and the decoupling performance is better.
