The surface of middle position before and after frame, the fixed rail is arranged on base, and is located at the outer side position in wheel bottom, fixed
The top of rail is used for supporting the lateral wheel tread of the bogie of car, and pressure sensing is provided with the track slot of each fixed rail
Device；The running test device includes running-in system and elevating mechanism, and the running-in system is located at the inner side position in wheel bottom,
And realize that height is adjusted by the elevating mechanism on base, the friction pulley of the running-in system is located at wheel
The underface of bottom inside wheel rim；Each wheel of the bogie of car is equipped with a fixed rail and a running adaptation dress
Put, the lifting support system is located at the underface of bogie of car barycenter.
As the preferred of such scheme, the lifting support system is made up of four lifting supports, this four lifting supports
It is in rectangular layout in the underface of bogie of car barycenter.
Beneficial effects of the present invention：Static-load testing device, running test device and function of weighing are integrated in one, effectively
Ground saves space, it is no longer necessary to which crane carries out transfer, greatly reduces handling workload, improves operating efficiency and sets
It is standby safe for operation, and static-load testing device and running test device is integrally disposed makes process layout more reasonable, maintenance and dimension
Shield is more convenient, efficient.

Fig. 1 is state of the present invention in running adaptation.
Fig. 2 is Fig. 1 B portions enlarged drawing.
Fig. 3 is Fig. 1 left view.
Fig. 4 is state of the present invention in static test.
Fig. 5 is state of the present invention when weighing.
Embodiment
By way of example and in conjunction with the accompanying drawings, the invention will be further described：
With reference to shown in Fig. 1-Fig. 3, a kind of bogie of car multi-function test stand, mainly by base 1, and base 1 is installed on
On static-load testing device, running test device and lifting support system 8 form.
With reference to shown in Fig. 1-Fig. 3, Fig. 5, static-load testing device is mainly by portal frame 2, hold-down devices 4 and fixed 5 groups of rail
Into.Hold-down devices 4 can move up and down along portal frame 2, hold-down devices 4 be located at middle position before and after bogie of car A just on
Side, bogie of car A is pressed by hold-down devices 4.Fixed rail 5 is arranged on base 1, and positioned at the bottom of wheel 3 in the outer part
Position, the top of fixed rail 5 are used for supporting the bogie of car A outside tread of wheel 3, bogie of car A each wheel 3
Equipped with a fixed rail 5, Fig. 4 show state during static test.
Pressure sensor is installed in the track slot of each fixed rail 5, when being weighed, hold-down devices 4 move up
And bogie of car A is left, Fig. 5 show state when weighing.
With reference to shown in Fig. 1-Fig. 3, running test device is mainly made up of running-in system 6 and elevating mechanism 7, running-in system 6
Realize that height is adjusted positioned at the inner side position in the bottom of wheel 3, and by the elevating mechanism 7 on base 1, running-in system
The friction pulley of system 6 is located at the underface of the bottom inside wheel rim of wheel 3.Bogie of car A each wheel 3 is equipped with a running-in
Experimental rig.Running-in system 6 adjusts height by elevating mechanism 7, and its extreme higher position is higher than fixed rail 5, extreme lower position ratio
Fixed rail 5 is low.
As shown in figure 3, running-in system 6 is provided with two friction pulleys, positioned at the underface of the bottom inside wheel rim of wheel 3, with
Wheel 3 is arranged in triangle disposition.During running adaptation, two friction pulleys are one in front and one in back in contact with the inner side wheel rim of wheel 3, wherein one
Individual friction pulley rotates as driving wheel, band motor car wheel 3, and wheel 3 drives another friction pulley to rotate and completes running adaptation again.
Lifting support system 8 is located at the underface of bogie of car A barycenter.Preferably, lifting support system 8 is risen by four
Descending branch post forms, and this four lifting supports are in rectangular layout in the underface of bogie of car A barycenter.
During static test, elevating mechanism 7 drives running-in system 6 to decline, fixed rail 5 and the bottom outside tread phase of wheel 3
Contact, hold-down devices 4, which move down, applies dead load completion experiment to bogie of car A；Afterwards, hold-down devices 4 move up,
Weighed；When carrying out running adaptation, lifting support system 8, which raises, jacks up bogie of car A, departs from bogie of car A
Fixed rail 5, behind the position for reaching setting, elevating mechanism 7 drives running-in system 6 to rise, the friction pulley and wheel of running-in system 6
3 bottom inside wheel rims are in contact.
Static test and weighing is carried out on fixed rail 5, and running adaptation is enterprising in the running-in system 6 of belt lifting mechanism 7
OK, after mainly terminating in view of compbined test, bogie of car A rolls multi-function test stand away from along fixed rail, it is not necessary to looks for
Flat and leveling, it is very convenient；It is assumed that the rail of static test is made into movable rail, and the running-in system 6 of running adaptation is done
Into fixed, after completing compbined test, bogie of car A, which is required to return on rail, can just roll multi-function test stand away from, due to rail
Lifted, it is necessary to levelling and leveling is carried out again, it is very troublesome.Moreover need to carry out testing equipment during experiment
When maintenance and replacing, it is only necessary to jacked up bogie of car A by lifting support system 8, just in testing equipment and vehicle
Service clearance has been vacateed between bogie A, it is not necessary to which bogie of car A rolls testing equipment away from, when maintenance completion is debugged, rises
Descending branch support system 8 moves down, and has saved maintenance time.Finally, when turning to running adaptation by static test, it is not necessary to by liter
Descending mechanism 7 and running-in system 6 jack up bogie of car A, but are first sent to bogie of car A by lifting support system 8 suitable
When position after, then running-in system 6 will be jacked up by elevating mechanism 7, and improve the service life of running-in system, reduce maintenance frequency
Rate.
