The embodiment of the present invention provides a kind of Undercarriage structure of magnetic-levitation train.The structure includes：Train bottom plate and at least one first slide unit being arranged on train bottom plate；First slide unit includes two crossbeams and two bogie connecting plates, two crossbeams it is parallel and along the direction vertical with train direct of travel across train bottom plate is welded on towards on the surface of bogie side, two bogie connecting plates are connected across on the end of two crossbeams respectively.The Undercarriage structure of magnetic-levitation train provided in an embodiment of the present invention, train bottom plate is connected with bogie by the first slide unit, first slide unit includes the bogie connecting plate for being connected with bogie and the crossbeam of support is provided for bogie connecting plate, its simple in construction and lighter in weight, it disclosure satisfy that magnetic-levitation train need not overcome friction vibrations and as far as possible light-weighted demand.
The Undercarriage structure of magnetic-levitation train
The present invention relates to train Undercarriage structure, more particularly to a kind of Undercarriage structure of magnetic-levitation train.
Magnetic-levitation train is that train is suspended on track using electromagnetic force, by linear motor directly drive and advance The train run in the air.Different from the wheel-track type train that other need to contact ground when magnetic-levitation train is walked, realize contactless Operation, only by the resistance from air, there is ride comfort, safe for operation, route selection is flexible, save land environmental protection, noise low vibration It is small to wait significant advantage.Thus, magnetic-levitation train overcomes ordinary train vehicle must realize train traction and resistance by Wheel Rail Contact The drawbacks of power is larger, open the new prospect of railway traffic.
Existing wheel-track type train is that the pillow pulling at vehicle body bottom frame position delays structure by being run with the wheel-rail friction of interorbital By be connected with turning to aerial spring, car body is connected with bogie, pillow pulling delays, empty spring and other etc. structure transported to reduce train Mechanical Contact, friction, loss and vibrations during row so that existing train chassis is provided with the structure of complexity and larger weight Amount.
And magnetic-levitation train is due to only by the resistance from air, without Mechanical Contact, friction and loss, making the floating row of magnetic Bearing and lubricating structure are not needed between the Undercarriage structure and bogie of car；Also wheel and the transmission of traditional wheel-track type train are eliminated Mechanism.Simultaneously as train is suspended on track by magnetic-levitation train using electromagnetic force, the weight of train chassis should it is more light more It is good.Thus complicated and weight the Undercarriage structure of existing wheel-track type train is completely unsuitable for magnetic-levitation train.
The present invention provides a kind of Undercarriage structure of magnetic-levitation train, for solving the Undercarriage structure of existing wheel-track type train discomfort The problem of for magnetic-levitation train.
The present invention provides a kind of Undercarriage structure of magnetic-levitation train, including：Train bottom plate and it is arranged on the train bottom plate On at least one first slide unit；
First slide unit includes two crossbeams and two bogie connecting plates, and two crossbeams are parallel and edge and train The vertical direction of direct of travel is across being welded on the train bottom plate towards on the surface of bogie side, described two bogies Connecting plate is connected across on the end of two crossbeams respectively.
The Undercarriage structure of magnetic-levitation train provided in an embodiment of the present invention, train bottom plate and bogie are connected by the first slide unit Connect, first slide unit includes the bogie connecting plate for being connected with bogie and the horizontal stroke of support is provided for bogie connecting plate Beam, its simple in construction and lighter in weight, it disclosure satisfy that magnetic-levitation train need not overcome friction vibrations and as far as possible light-weighted demand.
