The structure of the load cylinder on the gantry frame structure of system testing stand 2, portal frame is consistent with the structure of aerating pipe.
Hereinafter, the course of work of the present invention is sketched:
Tested bogie enters its Accreditation Waiting Area from the upper station of empty spring systems test bed 2, on empty spring places backing plate, opens
The operational control cabinet 12 of static test bed 1, starts oil pump air pump assembly 13, pushes tested bogie to sky spring systems test bed 2,
Decline the empty spring load cylinder 22 of simulation car body weight and load-carrying so as to load the air inlet that pressure head 221 is directed at empty spring, tested
The front and back wheel of bogie arranges stirrup strap, makes tested bogie not produce scroll forward and backward in test process;Due to each turn
Can there is difference in the load applied to frame, then be manipulated by loading force of the cabinet 12 according to needed for tested bogie to by preliminary operation
Apply suitable load to frame;Regulation air pressure is inflated to simultaneously to empty spring, in each joint of empty spring systems test bed, such as differential pressure
Apply at valve and touch suds, each joint is observed with the presence or absence of leakage.After the static pressure stipulated time, system records tested bogie automatically
The drop-out value of hollow spring air pressure, the value must be within the limits prescribed;Then, close empty spring air inlet, allow tested bogie its
In an empty spring A deflate, as two empty springs of tested bogie are connected by pipeline and differential valve, then its another empty
Spring B also can produce aerofluxuss simultaneously;Due to the presence of differential valve, the remaining pressure of empty spring B should be greater than atmospheric pressure, this remaining pressure
Value must be within the limits prescribed;Turn off the air vent of the air pump in 1 oiling pump air pump assembly 13 of static test bed, and be by
Two empty springs inflations of examination bogie, after inflation is finished, make sky spring B aerofluxuss, then watch the remaining pressure value of sky spring A, and this is remaining
Pressure value also must be within the limits prescribed.When empty spring does not have leakage and the remaining pressure value of differential valve meets regulation, right
Empty spring is exhausted, and lifts the piston rod that empty spring loads oil hydraulic cylinder, lays down 4 stirrup straps, bogie is pushed to static test bed 1
Accreditation Waiting Area.
1 modulated bearing of static test bed away from and 4 wheel load measurement apparatus 18 equal with the wheelbase of tested bogie with regard to
Under conditions of static load load cylinder 16 is all around symmetrical, starts the liter guide rail 19 of static test bed 1, be allowed to flat with ground
Together.By by empty 2 pass the test of spring systems test bed and the tested bogie of the Accreditation Waiting Area for being placed on static test bed 1 is manually pushed away
Deliver in the test mechanism of static test bed 1, make 4 wheels of tested bogie be located in 4 wheel load measurement apparatus 18 and just go up
Side, while lower falling-rising guide rail 142 is to minimum point, now tested bogie will rest upon 8 of 4 wheel load measurement apparatus 18
On support roller.Then, 8 support rollers are driven to rotate, between the wheel of support roller bogie in the presence of Creep Forces and creep torque, by
On the T-slot rail plate 141 that the bottom of 4 wheel load measurement apparatus 18 is simply seated in lubricating oil, non-bolted joint,
Frictional force very little and there is gap, so the position of 4 wheel load measurement apparatus 18 can be made according to the position of 4 wheels of bogie
Small adjustment.Decline static load load cylinder 15, due to being previously adjusted work, the dynamic head of making of each static load load cylinder 16 can be certainly
The air inlet of the dynamic empty spring for being directed at tested bogie, continues to be loaded onto ordinance load, while authorized pressure is inflated to empty spring, then
Secondary drive 8 wheel supports to rotate, make the position of 4 wheel load measurement apparatus 18 according to the position of 4 wheels of tested bogie make into
The small adjustment of one step.Stop driving, each wheel of the laser sensor automatic measurement in 18 central authorities of wheel load measurement apparatus relative to
The abscissa of static test bed 1, vertical coordinate of each wheel of measure track automatic measurement relative to static test bed 1, according to 2 points
Between range formula, such system calculates the wheelbase of the bogie left and right sides and its difference automatically, two diagonal of bogie and
Its difference;The pressure transducer test of wheel load measurement apparatus bottom obtains the wheel weight of 4 wheels of tested bogie and its difference.One
As for, wheel-base bogie and its difference, two diagonal of bogie and its difference were measured in preceding processes, used as redundancy
Control, merely just makees further check;For wheel weight and its difference of 4 wheels, some bogies can not meet requirement,
Should now there is cushioning below axle spring, be operated by the method regulation of test program, be not further described.For motor-car is turned to
Frame, in the difference in height that static test bed 1 will also measure two datum mark of the gear-box of bogie and traction electric machine, method is in standard
Horizon rule is disposed across in liter guide rail 19, on the basis of horizon rule, using vernier height gauge prototype gear case and traction electric machine
Difference in height, if the difference is unsatisfactory for requiring, gear-box suspension rod height should be carried out by the requirement of technical papers and method
Adjustment.According to the requirement of test program, static test bed needs under ordinance load effect repeatedly to try tested bogie
Test.When the tested bogie for being located at static test bed 1 respectively test corner qualified after, lift the piston rod of static load load cylinder 16 extremely
Proper height, rises promotion guide rail 142, is allowed to concordant with ground, the bogie of pass the test is manually pushed to next station.
Repeat above-mentioned work, the next bogie of test is so sequentially carried out, and makes sky spring systems test bed 2 and static load examination
Test platform 1 to be operated according to production task.
In addition, the present invention also has other variant embodiments, for example:Static test bed 1 in the present invention directly can be utilized
Static test bed of the prior art is transformed, that is, on the basis of existing static loading experiment platform, to existing static loading experiment platform
Hydraulic circuit and inflation gas circuit transformed, set up the hydraulic pressure of 2 branches on the hydraulic main circuit of existing static test bed
Loop, and be concatenated in two empty spring static load oil cylinders by a hydraulic control valve respectively;While filling in existing static test bed
The inflation gas circuit of 2 tunnel branches is set up in the main gas circuit of gas, and two empty spring aerating pipes are linked into by a gas path control valve respectively.
Relative to prior art, Efficient track bogie of car static test equipment of the present invention substantially increases experiment work
Efficiency, the function that can preferably play each device, minimizing space utilization, save construction investment.
Above-mentioned embodiment is the invention is not limited in, if to various changes of the invention or deformation without departing from the present invention
Spirit and scope, if these change and deformation belong to the present invention claim and equivalent technologies within the scope of, then this
Bright be also intended to comprising these change and deform.
