Embodiment Construction
[0030] The leaf spring test bench of the present invention is an innovation for possible problems in the experimental data of the existing traditional leaf spring test bench.
[0031] Such as figure 1 Shown is the structure diagram of the leaf spring test bench of the present invention, the test bench can be applied to various types of leaf springs, and leaf springs of different lengths can be installed in the width direction of the bench. Such as Figure 4 As shown, the coordinate system of the leaf spring test bench, the X direction, the Y direction and the Z direction represent the transverse, longitudinal and vertical directions respectively.
[0032] Such as figure 1As shown, the automobile suspension leaf spring test bench of the present invention includes a main console 16, a column 1 on the main console 16 and a test bench frame bearing beam 7, and the main loading hydraulic cylinder fixed bracket 2 is located at the column 1 The upper part of the main loading hydra...

The invention designs and develops a new set of leaf spring test bench for automobile suspension, which is characterized in that it can accurately simulate the stiffness performance and fatigue life test of the suspension leaf spring. This test bench can accurately extract the installation hard point of the leaf spring on the real vehicle and accurately simulate the installation environment of the real vehicle. The leaf spring is installed through the front and rear lifting lug brackets, so that the force and jump of the leaf spring when it is loaded fully conforms to the state of the real vehicle. Thereby, the actual stress of the leaf spring can be accurately simulated, and the accuracy of the leaf spring bench test can be improved. The new bench of the present invention can quickly and accurately extract leaf spring performance data and carry out fatigue tests at the stage of automobile design, and accurately simulate the movement track and force of leaf springs in actual working conditions; the test equipment is suitable for various types of Leaf spring, which integrates the static stiffness test and fatigue test of the leaf spring, accurately reflects the problems of the leaf spring in the design state, and can largely assist car companies to find problems in the design stage, improve product quality, shorten the vehicle development cycle, and reduce costs and risks.
Description
technical field [0001] The invention relates to a test bench for automobile suspension leaf springs, in particular to a test bench for the design and manufacture of automobile suspension leaf springs, and belongs to the technical field of automobile manufacturing and testing. Background technique [0002] Leaf spring is one of the most widely used springs in automobile suspension system. In addition to acting as an elastic element, it also acts as a guiding system, and the friction between multiple leaf springs also acts as a damping system. Because of its simple structure, convenient maintenance and relatively low cost, the leaf spring has been widely used in the field of automobiles, especially in trucks and mini-cars. [0003] The country has legal requirements for the test of the leaf spring of the automobile suspension. The main engine factory will carry out the fatigue test of the leaf spring in advance before the relevant institutions stipulated by the state, and carr...
