At present, when the locomotive whole-vehicle dynamic test stand was tested locomotive, the locomotive shaft pitch adjusting device of use can not be adjusted single gear unit, and all gear units must be adjusted simultaneously accordingly.Use conventional methods locomotive axle when adjusting, owing to regulate simultaneously between all gear units, so whole adjusting control procedure more complicated, and current regulating device does not have the function of automatic displacement calculating amount.Therefore have many drawbacks, such as a position out of true of train wheel after adjusting, automatic displacement calculating amount, so adjustment process is cumbersome, the test setup time that takies is also long.Because whole control set for adjusting more complicated, so also be not easy to maintenance.
The utility model content
The purpose of this utility model is to provide a kind of railway locomotive complete vehicle test bed that is applied to use locomotive axle apart from adjusting Askania, it can realize single gear unit independent regulation, can realize simultaneously position correction, automatic displacement calculating amount, can significantly save and test setup time.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of locomotive axle comprises hydraulic system and the supervisory control desk that hydraulic system is controlled, a plurality of gear unit and orders about the power decelerator that gear unit moves apart from adjusting Askania; A plurality of holding nut mechanism is installed on the gear unit, and holding nut mechanism comprises hydraulic jack and nut assembly; Supervisory control desk is controlled hydraulic system to the action of one or more gear units by hydraulic system is sent instruction, and the nut assembly of clamping on the gear unit makes it and can not rotate; Power decelerator is used for controlling the movement of gear unit, drives the corresponding adjusting of large chain-wales with this.
Further, hydraulic system comprises Hydraulic Station and fluid pressure line, one end of fluid pressure line links to each other with Hydraulic Station respectively, the other end links to each other with holding nut mechanism on the gear unit respectively, Hydraulic Station flows into by the liquid of the hydraulic jack in the holding nut mechanism in the fluid pressure line control gear unit, and then clamps holding nut mechanism and make it and can not rotate.
Further, gear unit also comprises commutator and leading screw, described commutator one end is connected with power decelerator, one end is connected with leading screw, and a plurality of holding nut mechanism is installed on the leading screw, between the described holding nut mechanism certain interval is arranged, power decelerator drives the rotation of leading screw by commutator, nut assembly on the leading screw is moved along leading screw, drive the corresponding adjusting of large chain-wales, thereby regulate the distance between each rail wheel.
As preferably, the number of holding nut mechanism is at least 3.
The beneficial effects of the utility model are, because hydraulic control system links to each other separately with each gear unit, so hydraulic control system can realize the adjusting to the single transmission unit.Owing in the supervisory control desk computer program being installed, computer program can be realized to the size of regulating accurate control, this mechanism make each step very accurate but also can control, so can realize the function to position correction, automatic displacement calculating amount.Because adjustment process is very simple, other preliminary work that it goes without doing before regulating is so can significantly save the setup time of test.And this mechanism is fairly simple durable, so maintaining at ordinary times is more convenient.
