Abstract
The utility model discloses a tractor suspension device lifting capacity test bench which comprises a fixing device installed on the front end of a tested tractor, a suspension frame device installed on the rear end of the tested tractor and a loading device. The loading device includes two electric cylinders and two tracks, wherein one electric cylinder is used for loading a suspension frame and is called a loading electric cylinder. The loading electric cylinder is installed in the two horizontal tracks parallel to the longitudinal central surface of the tractor and can move forward and backward along the longitudinal central surface of the tractor. The other electric cylinder is an adjusting electric cylinder and can push (or pull) the loading electric cylinder to move forward and backward in the longitudinal central surface of the tractor so as to keep the pull force applied by the loading electric cylinder on the suspension frame always vertically downward. According to the tractor suspension device lifting capacity test bench, loading is carried out by the electric cylinder. The tractor suspension device lifting capacity test bench has the advantages of being simple in structure, small in size, high in reliability, maintenance-free, high in precision and easy to control.
