Testing device for oil-gas suspension bracket

Abstract

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.

Description

technical field [0001] The invention relates to an oil-gas suspension testing device. Background technique [0002] Suspension system is the general term for all force transmission connection devices between the frame and the axle, which play the role of buffering, shock absorption and guiding. The suspension system has a decisive influence on the steering, handling stability, ride comfort, etc. of the vehicle, and is an indispensable part of the vehicle. With the continuous improvement of large-scale engineering and special vehicles' requirements for carrying capacity and off-road performance, the oil-pneumatic suspension meets the requirements of various vehicles with its superior nonlinear characteristics and damping performance. Therefore, the oil-pneumatic suspension system is used as a multi-axle One of the two key technologies of the chassis is an important subject to ensure that the multi-axle steering vehicle has good handling stability and ride comfort at the same...

Problems solved by technology

[0003] There are many studies on oil-pneumatic suspension at home and abroad, but they mainly focus on the research on the influence of oil-pneumatic suspension system on the ride comfort of the vehicle. There are few studies on the steering performance of the oil-pneumatic suspension system. Optimization research is even more lacking

At present, most of the test equipment can only be applied to the analysis of the characteristics of a single or single-axle suspension system, which seriously restricts the research on the vehicle coupling characteristics of the oil-pneumatic suspension system
