Abstract
A kind of 5-axle car for railway transport use belongs to the transport facility class.5-axle car is had a unique texture by car body, two two-axle bogies, one single shaft center wheel constitutes device etc.This single shaft center wheel had both been born vertical load to device, and car body freely traverses relatively again, can pass through plane curve safely, track switch and pass through hump vertical curve etc.The transportation of employing 5-axle car, its heavy below 21 tons of existing track permission that remain on, load-carrying can be brought up to 75 tons by present 60 tons, and the existing 60 tons of cars of unit train capacity improve 20%, are fit to present domestic general.
Description
The present invention relates to a kind of railway transports with five open-top cars.
At present, China Railway is in tension, has only 60 tons and the load carrying ability of existing four open-top cars is the highest, can not alleviate the nervous situation of transportation.If the development high capacity waggon, the general employing improved the heavy mode of axle, is about to that axle is heavy to be increased to 25 tons of E axle by 21 tons on D axle, and like this, load carrying ability is increased to 75 tons by 60 tons, is replaced by heavy rail more than 60 kilograms/meter but must will have railway track now.The high capacity waggon of E axle is adopted in development, limit by national power, can not realize in considerable time.
The object of the present invention is to provide and a kind ofly can improve load carrying ability, do not need to change the 5-axle car for railway transport use of railway track again.
Technical scheme of the present invention is the lower central at existing four open-top car car bodies, set up a single shaft center wheel to device, on car body, be provided with the single shaft wheel is carried out the drawing strickle guide seat of longitudinal spacing to device, transport with five open-top cars, improve the load-carrying ability of this car thereby constitute railway.Require center wheel to installing the vertical load that to bear qualification during design, can guarantee the circuit of five open-top car safety again by various states such as plane curve, track switch, line of torsion, humps.
Fig. 1 is the present invention program's structural representation; 1-two-axle bogie wherein; The 2-car body; The 3-center wheel is to device; The 4-two-axle bogie.
Fig. 2 looks scheme drawing for center wheel to installing the master; Wherein the 5-standard wheels is right, the 6-antifriction-bearing box, and 7-passes carrier, 8-spring, 9-axle box, 10-roller, 11-drawing strickle guide seat, 12-bolt.
Fig. 3 is that center wheel is to device A-A cross-sectional schematic.
Below in conjunction with accompanying drawing the present invention is further described:
The present invention is on the basis of existing four open-top cars, promptly in the lower central of car body (2), between two-axle bogie device (1) and the two-axle bogie device (4), set up a single shaft center wheel to device (3), thereby constitute five open-top cars (as shown in Figure 1).On car body (2), be provided with drawing strickle guide seat (11) center wheel is carried out longitudinal spacing to device (3).
Center wheel is an axle box (9) of being with the standard wheels of antifriction-bearing box (6) to (5), biography carrier (7) and both wings band spring (8) by one to device (3), and four carrying rollers (10) constitute.Pass carrier (7) and be bearing on the both sides axle box (9) by four springs (8), axle box (9) side has the drawing strickle guide groove, make pass carrier (7) vertically, laterally obtain spacing; By the effect of the drawing strickle guide seat (11) on the car body (2), standard wheels is carried out longitudinal spacing to (5) again.Be provided with the roller (10) that can guarantee that standard wheels is freely traversed with respect to car body (2) to (5) passing on (7) four jiaos of the carriers.Vertical load weight on the car body (2) passes on the carrier (7) by four rolling (10), reach standard wheels on (5) via journal box spring (8), axle box (9) again, because the effect of roller (10), standard wheels can freely be traversed with respect to car body (2) to (5), so that five open-top cars can pass through curve circuit safely.The nominal axes load that standard wheels be should bear (5) is by making journal box spring (8) have big natural bow and giving certain pre compressed magnitude and realize.
Fig. 2 and Fig. 3 have clearly illustrated that formation center wheel each position component relation to device (3), wheel is to (5), antifriction-bearing box (6) all adopts gauge member, passing carrier (7) is welded by shaped steel and steel plate, be carried on the spring (8), axle box (9) is steel casting with drawing strickle guide seat (11), axle box (9) is provided with the spring supporting seat, with bolt (12) with axle box, spring is linked and packed with the biography carrier, axle box (9) is connected with the axletree assembling by antifriction-bearing box, the axle box side has the drawing strickle guide groove, makes to pass carrier (7) vertically, laterally obtain spacing.Pass carrier and (7) four jiaos steel roller (10) is housed, can guarantee that standard wheels freely traverses to relative car body.
In sum, the present invention is on existing four axle open-top car bases, sets up a center wheel with unique texture to device, thereby consists of five axle open-top cars. Center wheel is provided with a roller biography year device to the biography carrier of device, makes center wheel both bear vertical load to device, and car body freely traverses relatively again, makes five axle open-top cars can pass through safely the circuit of the various states such as plane curve, track switch and hump vertical curve. The 5-axle car that adopts the present invention to produce, its axle is heavy remain on that existing track allows below 21 tons, load-carrying is brought up to 75 tons, unit train transportation energy by present 60 tons Power improves 20%, and it is current to have in the whole nation railway now, and needn't change existing railway track.
Claims (1)
