Abstract

The invention discloses a leaf spring assembly fatigue test bench. The leaf spring assembly fatigue test bench mainly comprises a base, a movable plate, guide columns, a tested leaf spring assembly, guide rails, trolley wheels, trolleys, a mandrel, and an air cylinder or oil cylinder; the air cylinder or oil cylinder is fixed on the base, and the piston rod of the air cylinder or oil cylinder is fixedly connected with the movable plate; the movable plate can slide along the guide columns under the driving the piston rod of thee air cylinder or oil cylinder; the trolleys are with provided with the trolley wheels; and the trolley wheels are arranged in the guide rails and can slide along the guide rails. When a test is carried out, the lifting lugs of the leaf spring assembly are installed on the trolleys, and the middle of the leaf spring assembly is fixedly connected with the movable plate, and then, the air cylinder or oil cylinder is started to work, and the real driving condition of a vehicle can be simulated, and a fatigue resistance impact test can be performed on the leaf spring assembly, and test time and the magnitude of load can be controlled by a computer. The leaf spring assembly fatigue test bench has the advantages of simple structure, accurate and reliable test results, convenient operation, high efficiency, high adaptability and the like. The leaf spring assembly fatigue test bench can be applied to fatigue resistance impact tests of leaf spring assemblies of different specifications.

Description

technical field [0001] The invention relates to the technical field of automobile leaf spring production, in particular to a leaf spring assembly fatigue test bench. Background technique [0002] The automobile leaf spring is an important part of the automobile suspension system, which is crucial to the technical performance and safety performance of the automobile, and the important factor affecting the rigidity of the automobile suspension system is the fatigue resistance of the leaf spring. When the car is running, the leaf spring, as the main shock absorbing and energy-absorbing component, has been subjected to fatigue load and impact load. Therefore, in the leaf spring production process, especially in the factory inspection process, it is necessary to conduct a fatigue test on the leaf spring to make its performance meet the national quality inspection standards. In this regard, general manufacturers now use real vehicle road tests to test the fatigue resistance and i...
