Testing device for oil-gas suspension bracket

The invention relates to a testing device for an oil-gas suspension bracket. The testing device is composed of a base plate, a plurality of excitation devices, single-bridge frames, frame connecting rods, a horizontal stabilizer bar, a mounting rod and oil-gas suspension cylinders. The multiple excitation devices are installed on the base plate; each two excitation devices form one group of excitation shafts; the multiple groups of excitation shafts are arranged at intervals along the length direction of the base plate; and the two excitation devices in each excitation shaft group are distributed at an interval along the width direction of the base plate. A rod end of each excitation device is hinged to one oil-gas suspension cylinder; and each group of excitation shafts corresponds to two oil-gas suspension cylinders. The two ends of each single-bridge frame are connected to the upper ends of the corresponding oil-gas suspension cylinders of one group of excitation shafts in a spherical hinge mode; and the each two adjacent single-bridge frames are connected by one frame connecting rod. A cylinder rod of one excitation device in each group of excitation shafts is connected with one end of the horizontal stabilizer bar in a spherical hinge mode and the other end of the horizontal stabilizer bar is connected with the lower end of the mounting rod in a spherical hinge mode; and the upper end of the mounting rod is installed at the middle part of the corresponding single-bridge frame. According to the invention, testing of various characteristics can be carried out on the whole automobile suspension bracket system.
