As the straight line traction electric machine vehicle of non-adhesion type of drive, the utilization in urban track traffic more and more is subjected to the attention of various countries.The straight line traction electric machine can be considered as a rotating machine and cut and the induction motor of flattening along radial direction, on the reaction rail that stator (magnet and coil) and rotor (tablet) are installed on the bogie of car respectively and track is middle, its mechanism is that the primary winding that is fixed on bogie truck passes through alternating current, produce shifting magnetic field (travelling-magnetic-field), the green phase mutual effect, make the secondary tablet (rotor of expansion) that is fixed on the solid bed produce magnetic field, realize the operation and the braking of vehicle by magnetic force (attract, repel).Bogie truck plays key role as the carrying and the running mechanism of vehicle: by one be, secondary suspension is isolated and extenuate from track to vehicle (comprising bogie truck self) element and the shock and vibration of manned or thing, for the linear electric motors vehicle, also to the Support Position be installed for linear electric motors provide, and the gap between assurance motor and reaction rail, the excessive tractive force deficiency that causes, too small then possibility is because vibration of vehicle make motor constantly clash into reaction rail.The linear electric motors vehicle is used for urban track traffic mostly, one of urban track traffic characteristics are exactly that radius of curve is little, therefore also to consider the curving performance of linear electric motors vehicle itself, guarantee that curving performance also will guarantee certain running velocity and higher travelling comfort simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of secondary framework crossbar of axle box linear electric motors bogie truck that can provide higher diamond resistant rigidity that certain directional tagging can be provided again.
The secondary framework crossbar of the axle box that the utility model proposes linear electric motors bogie truck, by drawing pull bar 1, electromagnetic rail brake parts 2, secondary framework 3, linear electric motors 4, linear electric motors sprung parts 5, framework 6, intertie 7, air bellow 8, wheel to 9, axle box 10, journal box spring 11, bolster 12, elastic side bearing 13, brake disc 14, cartridge 15, elastic caoutchouc support 16 and axle box lower bracket 17 form, its structure is as shown in Figure 1-Figure 3.Wherein, framework 6 is framed structure, bolster 12 is positioned at framework 6 middle parts, framework 6 evenly is divided into a left side, right half, the left side of framework 6, right both sides are distributed with secondary framework 3, wheel is to 9, axle box 10, journal box spring 11, wheel is provided with wheel to 9, each wheel is positioned at the two ends of framework 6 one sides, the inboard of each wheel is equipped with axle box 10, to 9, axle box 10 tops connect framework 6 by journal box spring 11 to axle box 10 by the bearing fifth wheel, and secondary framework 3 is V-shape, its two ends in two axle box 10 bottoms, are positioned at framework 6 left sides by bolt, two secondary frameworks 3 of right both sides connect by intertie 7; Bolster 12 has cartridge 15, and cartridge 15 connects framework 6 by elastic side bearing 13, and bolster 12 outside horizontal directions are provided with drawing pull bar 1; Linear electric motors 4 are positioned at two secondary framework 3 belows, be provided with elastic caoutchouc between secondary framework 3 and the linear electric motors 4 and support 16, the below of each axle box 10 is equipped with axle box lower bracket 17, linear electric motors 4 hang on any three axle box lower brackets 17 of framework 6 both sides by three straight machine sprung partses 5, electromagnetic rail brake parts 2 are positioned at bolster 12 belows, and be fixed in framework 6 bottoms, wheel is provided with brake disc 14 to 9.
The purpose of this utility model realizes: the single stage suspension device provides less horizontal and vertical rigidity according to designing requirement, adopt cartridge and the common bearing mode of elastic side bearing between framework and the bolster, between bolster and the car body laterally realizing by air bellow with vertical, vertically realize by drawing pull bar; Braking adopts electromagnetic rail brake to add the reel brake mode.
Working process of the present utility model is as follows: the secondary framework crossbar of this axle box linear electric motors bogie truck runs on the rail, owing to adopt secondary framework 3 and intertie 7 structures (displacement of restriction rhombus), two-wheeled is to 9 reliable location in the time of can guaranteeing linear running, and when curve motion, allow wheel to do radially or the splayed displacement to 9.When this bogie truck enters curve, rely on the creep power between wheel track, make bogie truck produce instantaneous revolution (wheel journal box spring 11 is had less horizontal and vertical rigidity), wheel can be in or approach radial position to 9, thus the abrasion of wheel rim and rail when reducing curve.
Useful producing effect of the present utility model is:
Pass through sharp radius curve in order to help vehicle, often choosing lower one is locating stiffness, and one be the linear running performance that the reduction of locating stiffness can reduce vehicle, the utility model organically is coupled together the secondary framework before and after the same bogie truck by intertie, and secondary framework is directly installed on the axle box, when linear running, can increase the right diamond resistant rigidity of same bogie truck front and back wheel like this, thereby improve vehicle linear running ability; Because bogie truck has lower one is locating stiffness, make bogie truck like this time again, keep wheel that wheel rim is not contacted with rail as far as possible by curve.The secondary framework crossbar of this axle box linear electric motors bogie truck, be mainly used in the linear electric motors vehicle, and be applicable to bogie truck and the vehicle that other adopt the secondary framework of similar axle box and have guiding mechanism, it can guarantee that the linear electric motors vehicle has enough linear running stability, simultaneously can guarantee that again wheel rim does not contact rail, make vehicle safety ground pass through sharp radius curve.
