Abstract
The utility model relates to a measuring device for experiment movement trails of an automobile leaf spring. The device can guarantee that the automobile leaf spring moves in a real automobile state, can be loaded at any interval to obtain enough measurement points, and can monitor the movement trails in real time to guarantee the accuracy of experiments. The device comprises the leaf spring, guide rails and two guide rail vehicles on the guide rails, and is characterized by also comprising a leaf spring clamping plate, a loading machine and a three-dimensional laser scanner, wherein each guide rail vehicle is provided with a rack, each rack comprises two bases and two parallel lugs which are connected with each other through a pin roll, the two bases of the racks are connected with each other through a cross beam, and one rack lug is connected with a lift lug.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly measures the measurement mechanism of its movement locus in a kind of leaf springs of car experiment.
Background technology
Front suspension adopts in the situation of leaf spring, when the upper and lower vibration of the relative vehicle frame of front-wheel, the orbiting motion that the pin joint that knuckle arm is connected with longitudinal tie will determine along spring leaf along with front-wheel on the one hand, swing around the longitudinal tie other end again simultaneously, if this two movement locus deviation is larger, can cause shimmy of front wheels and reverse impact.Consider in addition the difference that the leaf spring manufacturing is installed, need to test many groups of test exemplars, and every group of test exemplar carried out test of many times, the surveying work amount is large.Therefore, reasonably test method is to shortening the test period, and the movement locus at Measurement accuracy leaf spring main leaf center is extremely important.So far, there is no to measure accordingly the device of leaf spring movement locus.
The utility model content
For deficiency of the prior art, the utility model provides a kind of leaf springs of car experiment movement locus measurement mechanism, and this device can guarantee that leaf spring moves according to the real vehicle state, spacing loads arbitrarily, obtain enough measurement points, but and the Real Time Monitoring movement locus, guarantee to test accuracy.
In order to address the above problem, a kind of leaf springs of car experiment movement locus measurement mechanism of the present utility model, comprise leaf spring, guide rail and be arranged on two guide rail cars on guide rail, this leaf springs of car experiment movement locus measurement mechanism is characterised in that also and comprises: the leaf spring clamping plate, add carrier aircraft and three-dimensional laser scanner;
Each guide rail car is provided with support, and each support comprises base and two lugs parallel to each other, connects by bearing pin between two lugs; Connect by crossbeam between two bracket bases; Be connected with hanger on one of them support lug;
One end of leaf spring is connected with lug on a support, and the other end is connected with hanger on another support, the leaf spring clamping plate top with add the carrier aircraft output terminal and be connected, be connected with the leaf spring middle part below by U-bolts; The main leaf center of leaf spring, two ends and the crossbeam of leaf spring are provided with reflector plate, and three-dimensional laser scanner is arranged near guide rail, is used for the scanning reflection sheet.
Preferably, the xsect of described crossbeam is T shape.Be provided with cushion block between described bracket base and guide rail car.
The beneficial effects of the utility model are: in conjunction with experimental provision of the present utility model, in the situation that guarantee that the leaf spring forms of motion meets whole vehicle state, fast, measure accurately the movement locus in the relative leaf spring stiff end grasswort of leaf spring main leaf center, for the Proper Match of steering linkage and suspension guide mechanism provides Data support.
Description of drawings
Fig. 1 is the structural representation of leaf springs of car experiment bracing or strutting arrangement of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1, a kind of leaf springs of car experiment movement locus measurement mechanism of the present utility model comprises leaf spring 1, guide rail, is arranged on two guide rail cars on guide rail, leaf spring clamping plate 6, adds carrier aircraft 7 and three-dimensional laser scanner 9.Guide rail car is respectively fromer rail car and rear rail car, and the fromer rail car is provided with fore-stock 2, and the rear rail car is provided with after-poppet 3.The shape of two supports is similar, each support comprises base and two triangle lugs parallel to each other, connect by bearing pin between two lugs and be fixed on base, being connected with hanger 4 on the lug of after-poppet, being used for the leaf spring connected mode in simulation real vehicle situation.Connect by the T-shaped crossbeam 8 of an xsect between two bracket bases, be used for simulated automotive support longeron.Be provided with cushion block 4 between each bracket base and guide rail car.Select suitable cushion block 4 according to the leaf spring model, guarantee that support height is poor to meet the demands.One end of leaf spring is connected with lug on a support, and the other end is connected with hanger on another support, leaf spring clamping plate 6 top with add carrier aircraft 7 output terminals and be connected, be connected with the leaf spring middle part below by U-bolts.The main leaf center of leaf spring is equipped with a plurality of reflector plates on the two ends of leaf spring and crossbeam 2, and three-dimensional laser scanner 9 is arranged near guide rail, is used for the scanning reflection sheet.
When testing, two grasswort bolt place's stickup reflector plates at crossbeam 2, the main leaf center of testing leaf spring 1, test leaf spring, it is zero that adjustment adds carrier aircraft to load, scan with 9 pairs of all reflector plates of three-dimensional laser scanner, reference point as leaf spring main leaf central motion track, operation adds carrier aircraft 6 and loads by the interval of every 10mm, every loading 10mm reference point is the coordinate at reference scan test leaf spring main leaf center, after being loaded on the range of test leaf spring, begin unloading by the 10mm interval, continue scanning, scan altogether three groups of data.Test figure is imported in relative computer software, with the upper plane of this assembly of devices as the XY plane, as the XZ plane, coordinate system is converted to the car load coordinate system with the movement locus at test leaf spring main leaf center, move contrail fitting Cheng Yuan with test leaf spring main leaf center, the match center of circle and the theoretical center of circle are analyzed, complete test.
