The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
Such as Fig. 4, Fig. 6 and shown in Figure 7, a kind of bogie truck of embodiment of the present utility model comprises that bogie truck body 101, four wheels are to, bearing 102, adapter 103, cartridge and bottom side bearing 104.Each is taken turns the wheel 106 by an axle 105 and the middle part that is assemblied in axle 105 is formed.As shown in Figure 7, bogie truck body 101 comprises that the four road crossbeams 107 that arrange in pairs and be parallel to each other and the middle part of running through four road crossbeams 107 are for the link span 108 that four road crossbeams 107 are coupled together.The described wheel be assemblied in the two ends of every pair of crossbeam 107 by bearing 102 and adapter 103; It is right that namely the two ends of every pair of crossbeam 107 arrange respectively a wheel.Described cartridge is arranged on the middle part of two pairs of link spans 108 between the crossbeam 107; Link span 108 locates to be provided with respectively bottom side bearing 104 between every pair of crossbeam 107.
The utility model is by taking turns a right axis and change two semiaxis (namely being positioned at two axles 105 of link span 108 the same sides) into original, increased the alerting ability of bogie truck, greatly reduce the curve negotiating radius of bogie truck, to adapt to iron and steel enterprise's site layout project to the requirement of railway transport vehicle turn radius, under the prerequisite that guarantees the vehicle safety operation, make more compact and reasonable of field layout.
A kind of preferred version as the present embodiment, as shown in Figure 7, the bottom at the two ends of every pair of crossbeam 107 offers respectively corresponding groove 109, described two ends of taking turns right axle 105 are assemblied in the corresponding groove 109 of every pair of crossbeam 107 1 ends by bearing 102 and adapter 103 respectively, and the described right wheel 106 of taking turns is between twice crossbeam 9.
Continuation is in conjunction with Fig. 4 and Fig. 5, and as the another kind of preferred version of the present embodiment, the tread 111 that wheel 106 contacts with track 110 is the face of cylinder, and wheel 106 is plane contact with contacting of track 110.And the tread that the wheel of bogie truck of the prior art contacts with track is circular conical surface, and wheel is that line contacts with track.Therefore, bogie truck of the present utility model has increased the contact surface of wheel 106 with track 110, has guaranteed that wheel 106 contacts with the steady of track 110, prevents that wheel 106 from de-orbiting 110.
Another preferred version as the present embodiment, in order to increase the gap of wheel 106 and the side of track 110, so that turn to more flexible, and make when turning, reduce the wearing and tearing of wheel 106 and track 110, flange 112 thickness of the wheel 106 of this bogie truck have reduced 5mm compared to the thickness of flange of the wheel of prior art, and namely the thickness of the flange of the wheel 106 in the bogie truck of the present utility model is 26mm～29mm.
Another preferred version as the present embodiment, turn flexibly in order to make bogie truck of the present utility model, reduced the wheelbase of bogie truck, namely be arranged in the described wheelbase of taking turns right axle 105 of same to crossbeam 107 two ends two and reduce 40% than the wheelbase of the bogie truck of prior art same load.For example, when assumed load was a kilogram, the wheelbase of the bogie truck of prior art was b, and the wheelbase of bogie truck so of the present utility model then is (1-40%) * b1, reducing of the wheelbase of bogie truck of the present utility model strengthened the curve negotiation ability of bogie truck when turning.And, the suitable gap of design between adapter 103 and the bogie truck body 101, each is taken turns having more alerting ability when turning to make bogie truck.
In addition, the bearing in the present embodiment 102 adopts the biserial conical bearing of railway special use.Guarantee that bearing 102 bears bi-directional axial load when bearing radial weight, and can be in the end-play scope of bearing 102 the bi-directional axial displacement of restrictive axes 105.
As shown in Figure 5, cartridge in the present embodiment comprises body center plate 113, truck center plate 114 and cartridge pad 115, between body center plate 113 and the truck center plate 114 cartridge pad 115 is set, body center plate 113 and truck center plate 114 are assembled together by center pin 116, truck center plate 114 is bolted with bogie truck body 1, and body center plate 113 is installed on the vehicle body 118 by bolt 117.Guaranteed the location of bogie truck and vehicle body 118.
Continuation is in conjunction with Fig. 5, and crossbeam 107 and the link span 108 of the bogie truck body 101 in the present embodiment are integrated welded structure, and namely crossbeam 107 and link span 108 are integrally welded.
To shown in Figure 10, the bottom of vehicle body 118 is provided with two bogie trucks 100 such as Fig. 8, and the turn inside diameter with Fig. 8 vehicle body 118 extremely shown in Figure 10 is more flexible, and the curve negotiation ability on bend strengthens, and can greatly reduce the curve negotiating radius.
As shown in Figure 8, for the turning that guarantees bogie truck 100 and vehicle flexible, increased the gap between axle box (not shown) and the bogie side frame (not shown), the more common bogie truck of this gap value has increased 3mm, both guarantee the safe operation of vehicle, increased again the alerting ability that bogie truck 100 is turned.
Above embodiment is exemplary embodiment of the present utility model only, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in the protection domain of the present utility model.
