Description
Technical field
This utility model relates to Automobile Measuring Techniques field, particularly to a kind of device for automobile front axle steel plate spring assembly fatigue test.
Background technology
Propons steel plate spring assembly is the primary resilient parts of heavy-duty car suspension system, in order to ensure the performance of propons steel plate spring assembly, need, in design and manufacture process, be fully understood by and grasp propons steel plate spring assembly stress under various complex situations and deformation.
At present, domestic used automobile leaf spring assembly fatigue test method of testing is general with reference to GB/T 19844: be placed on by tested leaf spring on the free dolly in two ends, left and right, tests by applying concentrfated load in the middle part of leaf spring；There is the problem that in aforementioned test method, the set-up mode of leaf spring is not arranged according to actual entrucking situation, therefore experimental condition differs greatly with the true stressing conditions of leaf spring, secondly, stand easily produces resonance in process of the test, be there is certain impact in the accuracy of test data, it addition, the problem that when there is also test, bench run noise is bigger.
Summary of the invention
For the problem in background technology, the utility model proposes a kind of device for automobile front axle steel plate spring assembly fatigue test, its structure is: described device is made up of portal frame, two connection seats, two dual-axle hydraulic cylinders, two fixtures, press axle, two rubber limited blocks and two longitudinal beams；Described connection seat is arranged on the downside of portal frame crossbeam, and two connect between seat spaced, and two spacing distances connected between seat can regulate；Connecting and be connected by ball pivot between seat lower end and the upper piston rod of dual-axle hydraulic cylinder, two connect the most corresponding two the dual-axle hydraulic cylinders of seat；It is connected by ball pivot between the lower piston rod of dual-axle hydraulic cylinder and fixture, two the most corresponding two fixtures of dual-axle hydraulic cylinder；Pressure axle two ends are connected with two fixtures respectively；Two longitudinal beams are arranged at below pressure axle, and two rubber limited blocks are respectively arranged on the upper side of two longitudinal beams；Propons steel plate spring assembly to be measured is arranged on rubber limited block, and pressure axle downside contacts with propons steel plate spring assembly upper side to be measured；Described pressure axle uses the heavy-duty car front axle mated with propons steel plate spring assembly.
Compared with prior art, maximum the theing improvement is that of this utility model, change the set-up mode of propons steel plate spring assembly in assay device, propons steel plate spring assembly is connected (the most in opposite direction) fully according to actual entrucking situation with longitudinal beam, simultaneously, pressure axle for being further applied load is also adopted by the heavy-duty car front axle being consistent with practical situation, this just can simulate the true stressing conditions of propons steel plate spring assembly to greatest extent, during test, it is further applied load by the dual-axle hydraulic cylinder transmission axial propons steel plate spring assembly of pressure, thus the stressing conditions of propons steel plate spring assembly when simulating actual travel, by test data is analyzed, we just can grasp mechanical property and the fatigue life of propons steel plate spring assembly, thus be designed propons steel plate spring assembly targetedly improving.It addition, dual-axle hydraulic cylinder two ends are all provided with ball pivot, can be prevented effectively from assay device and resonate, and use dual-axle hydraulic cylinder to load, noise is less.
Advantageous Effects of the present utility model is: provide a kind of device for automobile front axle steel plate spring assembly fatigue test, and this device can simulate the actual loading situation of steel plate spring assembly, it is provided that tests data more accurately.
Accompanying drawing explanation
Fig. 1, this utility model structural representation；
Entitled corresponding to each labelling in figure: portal frame 1, connect seat 2, dual-axle hydraulic cylinder 3, fixture 4, pressure axle 5, propons steel plate spring assembly 6, rubber limited block 7, longitudinal beam 8.
Detailed description of the invention
A kind of device for automobile front axle steel plate spring assembly fatigue test, its structure is: described device is connected seat 3, two fixtures 4 of 2, two dual-axle hydraulic cylinders, pressure 5, two rubber limited blocks 7 of axle and two longitudinal beams 8 by portal frame 1, two and forms；Described connection seat 2 is arranged on the downside of portal frame 1 crossbeam, and two connect between seat 2 spaced, and two spacing distances connected between seat 2 can regulate；Connecting and be connected by ball pivot between seat 2 lower end and the upper piston rod of dual-axle hydraulic cylinder 3, two connect the most corresponding two the dual-axle hydraulic cylinders 3 of seat 2；It is connected by ball pivot between the lower piston rod of dual-axle hydraulic cylinder 3 with fixture 4, two the most corresponding two fixtures 4 of dual-axle hydraulic cylinder 3；Pressure axle 5 two ends are connected with two fixtures 4 respectively；Two longitudinal beams 8 are arranged at below pressure axle 5, and two rubber limited blocks 7 are respectively arranged on the upper side of two longitudinal beams 8；Propons steel plate spring assembly 6 to be measured is arranged on rubber limited block 7, and pressure axle 5 downside contacts with propons steel plate spring assembly 6 upper side to be measured；Described pressure axle 5 uses the heavy-duty car front axle mated with propons steel plate spring assembly.
When test prepares, connect the spacing distance between seat 2 according to pressure axle 5 length adjustment two, then pressure axle 5 is connected on fixture 4, then propons steel plate spring assembly 6 to be measured is arranged and put in place；After starting test, dual-axle hydraulic cylinder 3 providing power, drive pressure axle 5 to move up and down, pressure axle 5 carries out opposite direction pressure to propons steel plate spring assembly 6 to be measured, thus simulates load and the stroke change of car running process light plate main assemblage of spring.
