The technical scheme that the present invention adopts: the railroad track car bogie truck of band failure detector; Comprise framework, said framework top is provided with through draw gear and car body bonded assembly traction seat, and the framework bottom is provided with the elastic panel nodes seat; Said elastic panel nodes seat is connected with journal box body elasticity; Said journal box body and wheel are to being connected, and the support spring that framework is provided with, transverse damper and two are that vertical bumper constitutes car body secondary suspension system, and an end is supported on the journal box body; The journal box spring that the other end is supported on the framework lower end is that vertical bumper constitutes car body single stage suspension system with being arranged on one on the framework; The framework end is provided with unit brake, and said journal box body is provided with failure detector along between the rail direction, the spy of said failure detector wheel with take turns between the rail direct contact.
Wherein, Said failure detector comprises visits wheel erecting frame, spy wheel and control capsule; Captive joint with the axle box end cap of journal box body end in said spy wheel erecting frame two ends; Said spy wheel be arranged on visit on the wheel erecting frame and with the rail direct contact, said control capsule is located on the side plate of framework, and the electromagnetic valve in the control capsule through line with visit the flaw detection control mechanism of taking turns on the erecting frame and be connected.
Further, be shaped on the otic placode frame on the said axle box end cap, be shaped on mounting hole on the said otic placode frame, said spy wheel erecting frame end is inserted in the middle of the otic placode frame and with bearing pin and is fixed.
Further, said draw gear is connected with pivoted arm one end, and the said pivoted arm other end is connected with pipe link one end, and the said draw bar other end is connected with traction seat.
Further, said draw gear is a Z font center pin.
Further, said unit brake is the tread units drg, contacts brake wheel through brake shoe with tread.
The present invention's advantage compared with prior art:
1, solved in the former inspection car utilization process, because the inspection car dolly that guideway vehicle body oscillating in service causes vibration and then the vibration of spy wheel cause the low problem of flaw detection accuracy rate;
2, failure detector is connected with the bogie truck wheel shaft, has cut the flaw detection dolly, practiced thrift manufacturing cost; Remove the flaw detection dolly, also just cancelled the guard rail slide block that very easily damages on the former flaw detection dolly, eliminated traffic safety hidden danger;
3, the framework of this bogie truck adopts rectangle steel to be welded, and framework structure is simple;
4, adopt the height circle spring of advanced zigzag center pin draw gear, high camber to join transverse damper and vertical bumper, pivoted arm axle box positioning form; Make car load have good riding quality; Critical speed is high, and curving performance is good, and the wheel track horizontal force is little;
5, the braking of tread units drg is reliable, and maintaining is convenient, and the flaw detection accuracy rate is high.

The specific embodiment
Below in conjunction with accompanying drawing 1,2,3,4,5 a kind of embodiment of the present invention is described.
The railroad track car bogie truck of band failure detector; Said bogie truck comprises framework 1, and said framework 1 top is provided with through draw gear 3 and car body bonded assembly traction seat 11, specifically; Said draw gear 3 and 20 middle connections of pivoted arm; Said pivoted arm 20 1 ends are connected with draw bar 21 1 ends, and said pipe link 21 other ends are connected with traction seat 11 on the framework 1, and said draw gear 3 is a Z font center pin; Framework 1 bottom is provided with and journal box body 5 bonded assembly elastic panel nodes seats 14; Described journal box body 5 is connected with elastic panel nodes seat 14 through elastic panel nodes 13; Said journal box body 5 is connected 8 with wheel, and the support spring 2 that framework 1 is provided with, transverse damper 16 and two are that vertical bumper 4 constitutes car body secondary suspension system, wherein; The secondary suspension system is high circle spring supporting form, makes this bogie truck have good riding quality.One end is supported on journal box body 5 upper ends; The journal box spring 6 that the other end is supported on framework 1 lower end is that vertical bumper 7 constitutes car body single stage suspension system with being arranged on one on the framework 1; Framework 1 end is provided with unit brake 12; Said unit brake 12 is the tread units drg, contacts brake wheel through brake shoe with tread, is used for stopping or service brake.Said journal box body 5 is provided with failure detector along between the rail direction, the spy of said failure detector wheel 10 and wheel be to the rail direct contact between 8, guarantee to visit take turns 10 can both centering on the straight line of rail or curve; Specifically; Said failure detector comprises visits wheel erecting frame 17, spy wheel 10 and control capsule 9, and captive joint with the axle box end cap 15 of journal box body 5 ends in said spy wheel erecting frame 17 two ends, specifically; Be shaped on otic placode frame 18 on the said axle box end cap 15; Be shaped on mounting hole 19 on the said otic placode frame 18, said spy wheel erecting frame 17 ends are inserted in the middle of the otic placode frame 18 and with bearing pin and are fixed, thereby have avoided body oscillating to the flaw detection Effect on Performance; Guaranteed that when vehicle ' is detected a flaw visiting wheel 10 can be consistent with rail.Said spy wheel 10 be arranged on visit on the wheel erecting frame 17 and with the rail direct contact, said control capsule 9 is located on the side plate 22 of framework 1, and the electromagnetic valves in the control capsule 9 through line with visit the flaw detection control mechanism of taking turns on the erecting frame 17 and be connected.
