Description

A kind of test tool loaded for leaf spring three direction
Technical field
This utility model relates to auto parts and components test field, belongs to the test that a kind of automobile leaf spring three direction loads Frock, it is adaptable to the rigidity test of commercial car leaf spring and fatigue property test.
Background technology
The fatigue behaviour of leaf spring is one of important indicator of leaf spring, most important to the security performance of vehicle complete vehicle. Although also there is relevant standard in country to the fatigue test of leaf spring, but in national standard, specify only vertical load Fatigue test.But, in the process of moving, Leaf Spring Suspension is generally rushed vehicle by vertical force, brake force, uneven road surface Hit the various loading effect such as power.Obviously, the fatigue test of only Vertical loading mode, it is impossible to well reaction leaf spring is actual Fatigue behaviour in work.
For solving the problems referred to above, Chinese patent publication No. CN104949830A, date of publication JIUYUE in 2015 30 days, disclose A kind of automotive suspension leaf spring test-bed, by adjusting auxiliary hydraulic cylinder, changes the horizontal direction fortune of main loading hydraulic cylinder Dynamic track, it is achieved the vertically and laterally loading of both direction.Chinese patent publication No. CN105466703A, date of publication 2016 4 The moon 6, disclose a kind of steel plate spring assembly fatigue test board, by increasing sensor and foil gauge, carry out leaf spring total The vertical endurance impact inspection become.
There is presently no a kind of leaf spring testing stand and realize three directions loadings, simulation leaf spring is at real vehicle driving process In fatigue behaviour.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of test tool loaded for leaf spring three direction, pass through Control system, controls the load output of the servo hydraulic system in three directions, wheel and ground phase in simulated automotive driving process The stress of leaf spring during interaction, tested steel flat spring is laterally, longitudinally and the rigidity property in vertical three directions and tired Labor performance.
The technical solution adopted in the utility model is: a kind of test tool loaded for leaf spring three direction, including Leaf spring fixed support, it is characterised in that: it is placed with inverted leaf spring on described leaf spring fixed support, is inverted Leaf spring in the middle part of be upwards provided with simulating wheel support, respectively to horizontal, longitudinally and vertical three sides on simulating wheel support To being provided with servo hydraulic system, each servo hydraulic system is fixed by fixed support respectively, and horizontal servo hydraulic system is with solid Fixed rack one connects, and servo longitudinal hydraulic system and fixed support two connect, and vertical servo hydraulic system and fixed support three are even Connect.
Further it is improved by: wherein leaf spring fixed support is mainly made up of base and dolly, and base is fixed on On base plate, base is provided with guide rail, enables dolly to slide along guide rail, and the top of dolly is provided with for fixation steel plate spring end Draw-in groove.
Test method has two kinds:
Method 1 is applicable to the suspension system temporarily not having road examination loading spectrum signal: the design load according to leaf spring is true Determine vertical force, side force and longitudinal force theoretical value, then by software control system, export corresponding servo-hydraulic cylinder signal, Carry out rigidity and fatigue property test;
Method 2 is applicable to obtain the suspension system of road examination loading spectrum signal: according to the reality gathered in complete vehicle test field Border pumping signal carries out signal processing, it is thus achieved that the road examination stochastic signal spectrum of leaf spring, then utilizes software control system to obtaining The stochastic signal spectrum obtained carries out after-treatment, it is thus achieved that the driving signal spectrum of three servo hydraulic cylinders, carries out rigidity and fatigue behaviour Test.
Beneficial effect:
Simulating wheel support of the present utility model is used for junction steel plate spring and servo hydraulic system, by servo hydraulic system On load pass to leaf spring.Because being connected with servo hydraulic system and fixed support on simulating wheel support, it connects Position space coordinates is that the coordinate parameters according to wheel in vehicle actual moving process Yu ground contact surface converts, institute With the power by simulating wheel support transmission Hydrauservo System, the reality can simulated in leaf spring vehicle travel process is subject to Power state;Tested steel flat spring is laterally, longitudinally and the rigidity property in vertical three directions and fatigue behaviour.
Leaf spring fixed support is made up of base and dolly, and base end face is connected on ferrum floor, on base upper surface Having guide rail, so that dolly can slide along guide rail, described dolly is for fixing the end of leaf spring.Can be with the motion of simulated automotive State so that it is have a track moved, reaches the purpose of emulation.
Two kinds of test methods are divided into static and dynamic, and the load working condition of simulated automotive driving process light plate spring is carried out The rigidity in three directions and fatigue property test, the Curve guide impeller for leaf spring provides reliable test data in time.
Accompanying drawing explanation
Fig. 1 is the test-bed schematic diagram of leaf spring of the present utility model;
In figure, 1 is fixed support one, 2 transverse hydraulic servosystem, and 3 is vertical servo hydraulic system, 4 fixed supports two, 5 Being servo longitudinal hydraulic system, 6 is fixed support three, and 7 is leaf spring, and 8 is simulating wheel support, and 9 is base, and 10 is to lead Rail, 11 is dolly, and 12 is draw-in groove.
Detailed description of the invention
Below in conjunction with embodiment accompanying drawing 1, this utility model is described in further detail, but they are not intended that this The restriction of utility model, simultaneously by explanation, more can be aware and understand utility model.
A kind of test tool loaded for leaf spring three direction, including leaf spring fixed support, leaf spring is solid It is placed with inverted leaf spring 7 on fixed rack, in the middle part of inverted leaf spring 7, is upwards provided with simulating wheel support 8, simulate car Being provided with servo hydraulic system to three directions horizontal, longitudinal and vertical respectively on wheel support 8, each servo hydraulic system leads to respectively Crossing fixed support to fix, horizontal servo hydraulic system 2 and fixed support 1 connect, servo longitudinal hydraulic system 5 and fixed support 26 connect, and vertical servo hydraulic system 3 and fixed support 34 connect.
Wherein leaf spring fixed support is mainly made up of base 9 and dolly 11, and base 9 is fixed on base plate, on base 9 Being provided with guide rail 10, make dolly 11 can slide along guide rail 10, the top of dolly 10 is provided with the card for fixation steel plate spring 7 end Groove 12.
Test method has two kinds:
Method 1 is applicable to the suspension system temporarily not having road examination loading spectrum signal: the design load according to leaf spring is true Determine vertical force, side force and longitudinal force theoretical value, then by software control system, export corresponding servo-hydraulic cylinder signal, Carry out rigidity and fatigue property test;
