Background technology
Along with the fast development of urban track traffic, more and more higher to the technical requirement of subway Vehicular turn and brake system, the empty spring of railcar, bogie, wheel hub, gravity suffered by wheel is to turn to and brake system has a significant impact, empty spring, bogie, wheel hub, when suffered by wheel, gravity is large, suffered by the bogie of steering, gravity can increase, and the distance of brake system wheel can extend, empty spring, bogie, wheel hub, gravity hour suffered by wheel, suffered by the bogie of steering, gravity can reduce, the distance of brake system wheel can shorten, so railcar turn to and brake system sizing before, all need to carry out a large amount of performances and fail-test in testing table, these tests all will railcar handling capacity of passengers to empty spring, bogie, wheel hub, the impact of wheel is as important referential data, therefore the various load in the compartment simulating railcar in testing table is to empty spring, bogie, wheel hub, the impact of wheel just seems particularly important, but current known railcar turns to and in brake system test platform, does not all consider that load in railcar compartment is to empty spring during design, bogie, wheel hub, wheel affect data, so the test effect that can not reach.
Utility model content
To turn to and in brake system test platform to overcome existing railcar, all do not consider during design that load in railcar compartment is to empty spring, bogie, wheel hub, wheel affect data, so the drawback of the test effect that can not reach, the utility model provides a kind of by regulating the distance between cross bar and the empty spring of railcar being arranged on mandril of lifting jack front end, simulate the empty spring of railcar, bogie, wheel hub, various stress under the Different Weight load of wheel in compartment, thus under other associated assay devices coordinate, obtain the empty spring of railcar, bogie, wheel hub, the various stress datas of wheel under different gravity, for the load simulator that wheel steering system experiment and brake system test provide the Vehicular turn of relevant foundation and brake system test coordinative composition of equipments to use.
The utility model solves the technical scheme that its technical matters adopts:
The load simulator that Vehicular turn and brake system test coordinative composition of equipments use, it is characterized in that by upper bracket, side stand, lower carriage, lifting jack and cross bar are formed, upper bracket, side stand, lower carriage, cross bar is sheet metal, side stand has two, wherein a side stand upper end is arranged on left end under upper bracket, another side stand upper end is arranged on right-hand member under upper bracket, wherein a side stand lower end is arranged on left end on lower carriage, another side stand lower end is arranged on right-hand member on lower carriage, lower end in the middle part of upper bracket is arranged on bottom lifting jack, mandril of lifting jack front end is arranged in the middle part of cross bar, lifting jack is general-utility car maintenance hydraulic jack.
When this practicality uses, the empty spring of railcar, bogie, wheel hub and wheel are placed on the upper end of lower carriage, the cross bar being arranged on mandril of lifting jack front end is just positioned at the upper end of the empty spring of railcar.Move up and down the operating grip of lifting jack with hand when user uses, the push rod of lifting jack is moved down, when the push rod of lifting jack drives cross bar to move down apart from time large, empty spring acts on bogie, the acting force of wheel hub and wheel will increase, when the push rod of lifting jack drives cross bar to move down distance hour, empty spring acts on bogie, the acting force of wheel hub and wheel will reduce, so just act on bogie by empty spring, wheel hub, the size of wheel acting force, simulate bogie, wheel hub, the various force-bearing situations of wheel in compartment under different loads, under other associated assay devices coordinate, obtain empty spring, bogie, wheel hub, the various stress datas of wheel under different gravity, for vehicle turn to and brake system test provides related data.Based on more than, so the application prospect that the utility model has had.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; Fig. 2 is the empty spring of railcar, bogie, wheel hub and wheel are placed in schematic diagram when the utility model is tested.
In Fig. 1,1 is upper bracket, and 2 is side stands, and 3 is lower carriages, and 4 is lifting jack, and 5 is cross bars.
In Fig. 2,1 is the utility model, and 1-1 is lifting jack of the present utility model, and 1-2 is cross bar of the present utility model; 2 is empty springs of railcar, and 3 is bogies of railcar, and 4 is wheel hub of railcar, and 5 is wheels of railcar.
Embodiment
Shown in Fig. 1, the load simulator that Vehicular turn and brake system test coordinative composition of equipments use, by upper bracket 1, side stand 2, lower carriage 3, lifting jack 4 and cross bar 5 are formed, upper bracket 1, side stand 2, lower carriage 3, cross bar 5 is sheet metals, side stand 2 has two, wherein side stand 2 upper end is arranged on upper bracket 1 time left end, another side stand 2 upper end is arranged on upper bracket 1 time right-hand member, wherein side stand 2 lower end is arranged on left end on lower carriage 3, another side stand 2 lower end is arranged on right-hand member on lower carriage 3, lower end in the middle part of upper bracket 1 is arranged on bottom lifting jack 4, lifting jack 4 push rod front end is arranged in the middle part of cross bar 5, lifting jack 4 is general-utility car maintenance hydraulic jack.
