The utility model is concrete to adopt following technical scheme to realize: the general traveling of narrow gauge car portion module, contain wheel and axletree, wheel uses bearing fixing in the two ends of axletree, the axletree of wheel inboard is provided with and comprises the upper support seat, the suspended shock damper of damping spring and lower support seat, the lower support seat ring of suspended shock damper is placed on the axletree, lower support seat two ends are provided with the guide pillar tube, the guide pillar tube matches with two guide pillar bars that upper support seat bottom is provided with, screw rod top is passed lower support seat connection guide pillar bar rear lower and is fixed with nut, and damping spring is placed on the guide pillar tube and is pressed in, between the lower support seat.
Wheel and axle box are integrated, cancelled independent axle box, it is the journal box body that wheel is equivalent to traditional axle box, adopt bearing to be connected between wheel and axletree, so just realized same take turns to about two wheels can independently rotate, can be different when the rotating speed of vehicle left and right wheels during by curve, the slip during curve negotiating between the wheel track is less, the abrasion between wheel track can have been dropped to minimum; Shorten the length of axletree simultaneously, reduced productive costs and assembling difficulty, shortened the production cycle of module.
It is damping modes that the utility model adopts guide pillar guiding and cylindrical spring one, the guide pillar bar of upper support seat is with after the guide pillar tube of lower support seat cooperates, be connected with the lower support seat by screw rod and nut, upper and lower supporting seat compresses with the cylinder damper spring respectively, nut is by spring cotter locking, upper and lower supporting seat is connected as a single entity, can realizes guide function and shock-absorbing function horizontal, vertical, vertical direction during vehicle operating.
Compared with prior art, the general traveling of the narrow gauge car portion module that the utility model provides has following beneficial effect, that is:
1, has tapering because of wheel adopts A type tread, can prevent that wheel rim from depending merely on, reducing the wearing and tearing that wheel rim and rail are takeed on.
2, module adopts novel independently rotating wheel structure, has reduced wheel-rail wear and tear, has eliminated and has taken turns right hunting, has overcome the unstability of crawling, and has improved the riding quality of vehicle.
3, to have alleviated unsprung weight than module of the same type about 15% for the utility model, on year-on-year basis weight saving about 67kg, improved the vehicle operating quality effectively and reduced wheel-rail impact, improved the performance of module.
4, module has been cancelled independent axle box, has shortened the length of axletree, has therefore reduced productive costs and assembling difficulty, has shortened the production cycle simultaneously.The manufacturing cost of the every cover traveling of reality portion module reduces by 1000～2000 yuan.
5, the utility model has been considered the commonality of module, has realized the normalisation of individual system docking mouth, when other position of vehicle is adjusted, can not have influence on the normal use of general traveling portion module.The utility model for unit in charge of construction has saved a large amount of resources, has reduced buying and logistics cost applicable to the back conveyance vehicle of various batches, various vehicles.
