Description
Technical field
The present invention relates to wheel-rail train bogie technique field, especially, relate to a kind of power bogie for meter gauge.
Background technology
Bogie truck is as the critical component of wheel-rail train, and the quality of its performance directly affects the riding quality and the safe in operation of vehicle.In the middle of the formation of the overall weight of bogie truck, wheel is to occupying sizable ratio.Studies show that, adopt radial type connection and single axle truck can make car group weight reduce by 7～14%, can save 9% tractive output at most.
Single axle truck is not also developed at home, makes, was used, and is only limited to relevant academy of sciences and studies in theory, does not have ripe application experience to use for reference.Abroad, the systematic study of single axle truck theory also is inchoate in recent years, and successively have countries and regions to develop various sample cars and product and drop into commercial operation the same period.Wherein dropping into the comparatively successful vehicle of commercial operation comprises: the BM72 type battery-driven car group of Copenhagen, Denmark S-tog second generation battery-driven car group, German Lirex diesel coach set and Austrian Integral diesel coach set and Norway etc.
Single axle truck is used for passenger vehicle and starts from Denmark's state-owned railroads (Danish State Railways, suburbs, Copenhagen light rail car group S-tog DSB) at first.Its early stage car group is two joint marshallings, and its leading truck adopts the single axle truck of car body location.From the impression of taking, this car is very steady, and the wheel track noise is very little.The car group is behind operation 105km, and the wheel wear right to single axle truck and conventional steering framing wheel compares, and shows and can reduce wheel-rail wear.Early 1990s, DSB is when Development of New Generation S-tog light rail car group, the dress novel KERF bogie truck of cooperating by LHB company under French Alstom (ALSTOM) group and professor Frederich, this bogie truck dress radiai adjustment device that has the fluid pressure type Passive Control, even at axle heavily is under the 20t condition, bogie truck still has good radial performance on curve, so the abrasion of wheel are lower than conventional bogie truck.Railway experimental investigation center, Germany (FTZ) has been carried out correlation test to dress with the high-speed cruising feasibility of the vehicle of this bogie truck, and the highest test speed reaches 220km/h, and every index is all in UIC standard limit.
But existing single axle truck structure is more complicated all, and the traditional braking mode structure of employing is more complicated also; Single shaft power truck secondary suspension is that two air bellows directly support car body, and stability of structure is poor; Air bellow is seated at framework central authorities in addition, and is too small and cause traversing amount limited with the right transverse pitch of wheel.Whole bogie truck occupation space is also bigger, only is adapted at moving on the circuit of standard gauge, can not satisfy the needs of meter path road and narrow car body.
Summary of the invention
Technical matters to be solved by this invention provides a kind of power bogie for meter gauge, realizes integrally-built rational deployment, reduces integrally-built taking up room, and increases the traversing amount of bogie truck.
In order to address the above problem, the invention discloses a kind of power bogie for meter gauge, comprising: two support beams, single shaft wheel are to, gear case, two cover air-pressure disc brakes, four air bellows, two height-control valves, two drawing pull bar, two radius stays; Wherein, two wheels are fitted in directly that to form above-mentioned single shaft wheel on the axletree right, and brake disc also directly is fitted on the above-mentioned axletree, and above-mentioned wheel and brake disc rotate with above-mentioned axletree; On above-mentioned axletree, above-mentioned bearing and brake disc carry out located lateral by an axle sleeve to above-mentioned support beam by a bearings; The said gear case is installed on above-mentioned axletree middle part; Above-mentioned air-pressure disc brake is installed on the brake support frame, and above-mentioned brake support frame is connected on the above-mentioned support beam by a mount pad; Above-mentioned four air bellows are installed on four jiaos of above-mentioned two support beams respectively; Wherein, the height of per two above-mentioned air bellows is by an above-mentioned height-control valve control of being located on the same above-mentioned support beam; A drawing pull bar and a radius stay are installed on every above-mentioned support beam; The middle part of above-mentioned support beam is provided with horizontal backstop.
Preferably, above-mentioned support beam directly is supported on the above-mentioned axletree by a cover self sealss bearing of interior dress; Carry out located lateral by an axle sleeve between above-mentioned self sealss bearing and the brake disc.
Preferably, two of every above-mentioned support beam jiaos also are provided with two vertical oil-pressure dampeies.
Preferably, above-mentioned two support beams are the inblock cast structure.
Preferably, be cast with two air bellow seats, a drawing pull bar seat, a location pole socket and a horizontal stopping seat on every above-mentioned support beam; Be welded with a height valve seat.
Preferably, also be welded with two vertical oil-pressure damper seats on every above-mentioned support beam.
Preferably, each above-mentioned air bellow inside is provided with limiting stopper.
Compared with prior art, the present invention has the following advantages:
Power bogie for meter gauge provided by the invention, adopt the integral structure of single shaft wheel to forming with two support beams, the fatigue resistance and the load-carrying capacity of bogie truck have not only effectively been improved, and make the layout of each parts of bogie truck and integrated more reasonable, integral structure is compact more, effectively reduce taking up room of bogie truck, also saved material simultaneously, reduced the manufacturing cost of framework.
Adopt single axle truck to make car group weight reduce by 7～14%, saved 9% tractive output, structurally simplify greatly, reduced maintenance workload, and then reduced maintenance cost.In addition, adopt single axle truck, make full use of wheel, realized that wheel to the radiai adjustment on curve, has improved the curve negotiation ability of vehicle, reduced horizontal force, abrasion and the noise of wheel track the peculiar guide function of structure.
