The freight system adopting air rail transportation is widely focused on the market, and has good market prospect.

In the related art, no matter passenger transportation or freight transportation, a lower opening rail Liang Zhishi is generally adopted in a suspension type air rail transportation freight transportation system, and the freight transportation system adopts a solid rubber wheel or a pneumatic tire as a running mechanism, so that the suspension type air rail transportation freight transportation system has better shock absorption and comfort performance, but the rubber wheel has larger abrasion, shorter service life and higher operation and maintenance cost in the whole life cycle.

Based on the technical problems, the embodiment of the application provides an air track bogie and a transport vehicle, and aims to at least solve the technical problems that a freight system in the related art adopts a solid rubber wheel or a pneumatic tire as a running mechanism, the service life is short, and the operation and maintenance cost is high in the whole life cycle to a certain extent.

In a first aspect of the application, the application provides an aerial track bogie. Fig. 1 shows a schematic structural view of an aerial track bogie in one or more embodiments of the present application, and fig. 2 shows a schematic side view of fig. 1. Referring to fig. 1 and 2, the bogie comprises a frame 1 and a wheel set assembly 2, wherein the wheel set assembly 2 is arranged at the bottom of the frame 1 to support the frame 1. Fig. 3 shows a schematic structural diagram of the wheel set assembly in fig. 1, and in combination with fig. 3, the wheel set assembly 2 includes an axle 21, wheels 22, bearing saddles 23 and a first elastic member 24, the two wheels 22 are oppositely disposed at two ends of the axle 21, the wheels 22 are metal wheels, the two bearing saddles 23 are oppositely disposed on the axle 21, the bearing saddles 23 are respectively located at inner sides of the wheels 22 at the same side, the bearing saddles 23 are supported at the bottom of the frame 1, and the first elastic member 24 is disposed between the bearing saddles 23 and the frame 1.

According to the aerial track bogie provided by the application, as the axle 21 of the wheel set assembly 2 is provided with the two bearing saddles 23, the bearing saddles 23 are supported at the bottom of the framework 1, and when the framework 1 is driven to run, the wheels 22 of the wheel set assembly 2 can run on corresponding tracks through the bearing saddles 23; the wheel 22 formed by the wheel sets 2 is a metal wheel to replace a solid rubber wheel or a pneumatic tire in the related art, so that the wear degree in long-term high-frequency operation is small, the service life is long, the wheel is more suitable for the transportation requirements of large traffic, high frequency and long distance, the durability is high, the defect of excessively high maintenance cost of the solid rubber wheel or the pneumatic tire is avoided, the operation cost is reduced, and the market requirement is better met; in addition, through the first elastic piece 24 that sets up between adapter 23 and framework 1 to improve the shock attenuation and the travelling comfort of bogie operation in-process, satisfy the shock attenuation requirement of aerial railcar, have fine practicality.

In some embodiments, the metal wheel may be a steel wheel, and in other embodiments, the metal wheel may be made of an alloy material, which is not limited herein. The wheel 22 will now be further described as a steel wheel.

In the embodiment, the steel wheel has high durability, long service life and relatively low manufacturing cost and maintenance cost, and can better meet the requirements of the market on transportation cost and maintenance cost; in particular, in the field of freight transportation, the indexes such as noise, comfort and the like often have no higher requirements, and the requirements of a large ramp can be determined according to actual conditions without forced requirements. Therefore, for the application scene of partial air rail freight transportation, the transportation vehicle adopting the bogie provided by the embodiment of the application can better meet the requirements of the market on the operation cost.

Under certain application scenes, severe air track running environments such as large sand wind, large traffic, long ramp, large temperature difference and the like are faced. For example, on an empty track, the number of days of wind power exceeding 8 levels in the whole year is 177 days, the number of days exceeding 10 levels is 101 days, the number of days exceeding 11 levels is 67 days, and the highest operation wind speed even reaches 10 levels; the annual transport capacity is 1500 ten thousand t, and the annual operation days are 300 days; the whole line length is 66km, the altitude drop is about 1800m, and the maximum gradient is 60 per mill; the operation temperature difference reaches-25.5-48.0 ℃. Due to the self material and structure problems of the rubber wheel, the following problems exist when the rubber wheel is adopted as the running wheel of the overhead rail car: the heat dissipation performance is poor, the longest continuous operation time of a single test is 30 minutes, the heat dissipation is required to be carried out for 5 minutes, otherwise, the risks of rubber cracking, peeling or falling are existed; the service life is low, the annual running distance of the vehicle is about 30 ten thousand km according to 1500 ten thousand t running energy and 66km distance, and the service life of the rubber wheel is only 3.2 months; the lower speed, heavy duty wheel 22 speed up to 40km/h has been the limit; the maintenance cost is high, calculated according to 1500 ten thousand operating energy, the comprehensive maintenance cost of the solid rubber wheel is the lowest 7462 ten thousand per year, and the combined bicycle is 36.4 ten thousand per year.

In addition, the adoption of the rubber wheels can also have a certain influence on the air track beam, so that the air track beam is poor in fatigue resistance, poor in stress state of the rubber wheels and high in construction difficulty.

For example, for an open beam, rubber wheel pressure is a partial load, and fatigue performance is poor, resulting in increased annular reinforcing ribs of the track beam and reinforcing ribs at the bottom of the running surface, and in addition, the running surface is worn and corroded to cause thinning of the running plate and failure in repairing. For another example, the lower open box girder has an outward expansion trend under the pressure action of the running wheel, the running surface is in an inverted splayed shape, so that the inner side of the running wheel has a void trend, the pressure of the outer side is increased, the abrasion of the wheel 22 is increased, and the outer side crack of the running wheel is more than that of the inner side in the field. In addition, the uneven degree of the running surface and the large rigidity of the integral framework 1 cause serious load increase and decrease of the running wheels, and also cause increased abrasion. For another example, the air track beam has larger size control difficulty and later adjustment difficulty, and the related manufacturing size of the air track beam cannot strictly meet the design requirement, and the main reason is that the lower opening structure of the track beam causes smaller rigidity of the beam body and is not beneficial to size control; after the manufacture of the lower opening box girder is finished, the adjustment difficulty is great.

Aiming at the problems existing in the air rail transportation, the embodiment of the application provides an application concept of adopting steel wheels as travelling wheels of an air rail transportation vehicle beam. Compared with a transport vehicle with rubber wheels as travelling wheels, the steel wheels have the advantages of good heat radiation performance, large bearing capacity, good wear resistance, high speed, large climbing capacity, low maintenance cost, long service life, high safety performance and mature actual application condition, and can adopt a track based on a box-shaped beam structure, so that the construction size and later adjustment difficulty of the air track beam are small, and the air track vehicle adopting the steel wheels is more suitable for long-distance, high speed, high frequency and low noise requirement application scenes.

In addition, the air rail transportation system using the steel wheels has better economy, and is analyzed as follows:

Solid rubber wheel: estimated with 4 tens of thousands per single wheel cost and 5 years of rim life, then the vehicle is flatly spread to the purchasing cost 4*8/5=6.4 tens of thousands per year of single wheel, and the total vehicle rim cost is 6.4×205=1312 tens of thousands per year; every 8 ten thousand kilometers of rubber is replaced, the replacement cost is 1 ten thousand per year, the running mileage of a single vehicle is calculated to be 30 ten thousand kilometers per year, the tire of the single vehicle is required to be replaced 3.75 times per year, the vulcanizing cost of the single vehicle rubber is 1 x 8 x 3.75=30 ten thousand per year, and the total vehicle wheel replacement cost is 30 x 205=6150 ten thousand per year according to the total number of 205 vehicles; after synthesis, 7462 ten thousand/year.

Pneumatic tire: the tire replacement cost of the single vehicle is calculated by 0.5 ten thousand per unit of single wheel and once every 10 ten thousand kilometers, the tire replacement of the single vehicle is required to be carried out 3 times per year, the tire replacement cost of the single vehicle is calculated by 0.5 x8 x 3=12 ten thousand per year, and the total vehicle tire replacement cost is calculated by 205 vehicles, namely 12 x 205=2460 ten thousand per year; rim life is calculated by 5 years, the rim life is flatly spread to 0.5 x 8/5=0.8 ten thousand/year of a bicycle, and the rim replacement cost of all the bicycles is 0.8 x 205=164 ten thousand/year; after synthesis, 2624 ten thousand/year.

Steel wheel: calculated as 124 tens of thousands/kilometer of track (40 years), the track cost is 124 x 66 x 2 = 16368 tens of thousands, with an average of 409.2 tens of thousands per year; the service life of the steel wheel is 240 ten thousand kilometers, the steel wheel is replaced every 8 years, the cost of the steel wheel is estimated to be 0.34 ten thousand per year, the steel wheel is flatly distributed to the single-car steel wheel by about 0.34 x 8/8=0.34 ten thousand per year, and the total vehicle wheel replacement cost is 0.34 x 205=69.7 ten thousand per year; calculating according to 15 ten thousand kilometers of rotary repair once by 0.12 ten thousand, and leveling to 0.12 x 8 x 2=1.92 ten thousand per year of rotary repair of single-car steel wheels each year, wherein the rotary repair cost of all vehicles is 1.92 x 205= 393.6 ten thousand per year; the total time is 872.5 ten thousand per year.

From the above, if the steel wheel according to the embodiment of the present application is adopted, the cost of a single wheel is estimated to be 2.5 ten thousand, and the total cost is 1315.3 ten thousand/year. Compared comprehensively, the steel wheel has long service life and lower purchase and maintenance cost although the rail is put into a large amount at one time, and the cost in the whole life cycle is lower than that of the solid rubber wheel and the inflatable wheel.
