At present, in order to achieve the purpose of reducing noise, the traveling wheels of the existing suspension type monorail vehicle mostly adopt rubber wheels. The running wheels bear the gravity of the vehicle, and the abrasion of the rubber wheels is serious in the actual operation process, so that the operation and maintenance cost of the system is increased. In view of this, if suspension transportation is implemented in a magnetic suspension manner, it is considered that the problem can be optimized in three ways: firstly, the vehicle is completely free of direct mechanical contact with the rail in a vehicle suspension and non-contact driving mode so as to avoid mechanical impact and abrasion between the rubber wheels and a rail running surface; secondly, the positive pressure between the rubber wheel and the track is reduced by a suspension weight reduction mode, the mechanical impact and the frictional resistance borne by the rubber wheel are reduced, the purpose of prolonging the service life of the rubber wheel is achieved, and the rubber wheel is suitable for low-speed traffic; and thirdly, the non-contact with the rail is realized through the suspension of the vehicle, and the walking is realized through the side contact type driving of the rubber wheels.

Based on foretell second mode, the utility model provides a suspension type monorail train system with two formula electromagnetism subtract heavy mechanism, its characteristics are can effectively reduce the rubber tyer burden, prolong rubber tyer life, reduce the maintenance work load.
The technical scheme of the utility model as follows:
a suspended monorail train system with a double-row electromagnetic weight reduction mechanism is composed of a suspended track box girder, a bogie running on the track of the track box girder through rubber wheels on the suspended track box girder, and a train body suspended on the bogie. Be provided with double row formula electromagnetism between case roof beam track inboard and bogie and subtract heavy mechanism: two weight-reducing rails made of high-magnetic-flux materials are arranged at the top of the inner side of the box girder rail, and four weight-reducing electromagnets are arranged at the positions, right opposite to the weight-reducing rails, of the top of the bogie in a group two by two and are respectively in electromagnetic coupling with the two weight-reducing rails; four weight reducing controllers are arranged on the bogie and respectively control the working current of each weight reducing electromagnet; a distance sensor 112 for monitoring the distance between the upper surface of the weight-reducing electromagnet 102 and the weight-reducing rail 101 and a speed sensor 111 for monitoring the relative running speed of the bogie are also arranged on the bogie.
In this way, the weight-reducing rails are fixed at the upper surface positions in the track box girder of the suspension type monorail train system and are symmetrically arranged, and the weight-reducing electromagnets are installed at the upper part of the bogie of the suspension type monorail train system and correspond to the weight-reducing rails; the weight reduction controller is arranged on the bogie and is used for controlling the current input into the weight reduction electromagnet; the speed sensor is arranged on the bogie and used for providing train speed information for the weight loss controller; the distance sensor is arranged on the bogie and used for detecting the distance between the weight-reducing electromagnet and the weight-reducing rail and sending the distance value to the weight-reducing controller. And the weight reduction controller controls the current input into the weight reduction electromagnet according to the train speed value provided by the speed sensor and the distance value between the weight reduction electromagnet and the weight reduction rail provided by the distance sensor. The weight-reducing rail is designed into a flat plate type, so that the weight-reducing rail is convenient to manufacture, install and construct.
The weight reducing controller controls the current input into the weight reducing electromagnet according to the speed value, the larger the speed is, the larger the current input into the weight reducing electromagnet is, the larger the attraction force of the weight reducing rail on the weight reducing electromagnet is, and the weight reducing electromagnet is fixed on a bogie of the suspension type monorail train, so that the upward tension on the bogie is larger, and the pressure of a rubber wheel on the bogie on a corresponding rail on a rail box girder is smaller at the moment. On the contrary, the smaller the speed is, the smaller the current input into the weight-reducing electromagnet is, the smaller the attraction force of the weight-reducing rail on the weight-reducing electromagnet is, and the greater the pressure of the rubber wheel on the bogie to the corresponding rail on the rail box girder is.
When the train speed is low, the friction force between the rubber wheel and the rail is needed to drive the train speed to increase, so that in the case, a low-degree weight reduction mode is adopted, the pressure of the rubber wheel on the rail is large, and friction driving is facilitated. When the train is at a high speed, the train is in a state of maintaining the speed or slowly increasing the speed, the friction force between the rubber wheel and the rail is smaller, the running resistance is smaller, and the maintenance of the speed under the condition of low energy consumption is facilitated.
The weight reducing controller can also control the current input into the weight reducing electromagnet according to the distance value between the electromagnet and the weight reducing rail, because under the condition of the same current magnitude, the lower the distance value, the greater the attraction force between the weight reducing electromagnet and the weight reducing rail, because of the irregularity of the line, in the actual operation process, the distance value between the electromagnet and the weight reducing rail is not fixed, if the distance value is reduced, the current input into the weight reducing electromagnet is very large, and the fault that the train is sucked up to collide with the weight reducing rail due to the overlarge attraction force between the weight reducing electromagnet and the weight reducing rail may occur, so once the distance value is reduced and exceeds the allowable value, the weight reducing controller can interrupt the current input into the weight reducing electromagnet until the distance value is restored to be within the allowable range, and then resume the current input.

Referring to fig. 1, 2 and 3, 1 is a track box girder, 2 is a bogie, 3 is a rubber wheel, and 4 is a train body. The system comprises a weight reducing rail 101, a weight reducing rail 102, a weight reducing electromagnet 103, a weight reducing electromagnet 104, a weight reducing electromagnet 105, a weight reducing electromagnet 106, a weight reducing controller 107, a weight reducing controller 108, a weight reducing controller 109, a weight reducing controller 110, a speed sensor 111 and a distance sensor 112; the weight reducing rails 101 and the weight reducing rails 102 are fixed on the upper surface in a track box girder of the suspension type monorail train system and are symmetrically arranged, and the four weight reducing electromagnets (103, 104, 105 and 106) are installed on the upper part of a bogie of the suspension type monorail train system and correspond to the weight reducing rails; the weight loss controllers (107, 108, 109 and 110) are installed on a bogie, and the speed sensor 111 is installed on the bogie and is used for providing train speed information for the four weight loss controllers; the distance sensor 112 is mounted on the bogie and is used for detecting the distance between the upper surface of the distance sensor and the upper surface of the interior of the track box girder and sending the distance value to the four weight reduction controllers.
The cross sections of the weight reducing rails (101 and 102) are rectangular. The sections of the weight-reducing electromagnets (103, 104, 105 and 106) are all U-shaped.
The weight-reducing controller 107 controls the current input to the weight-reducing electromagnet 103 according to the train speed value provided by the speed sensor 111 and the distance value provided by the distance sensor 112; the weight-reducing controller 108 controls the magnitude of the current input to the weight-reducing electromagnet 104 according to the train speed value provided by the speed sensor 111 and the distance value provided by the distance sensor 112; the weight-reducing controller 109 controls the magnitude of the current input to the weight-reducing electromagnet 105 according to the train speed value provided by the speed sensor 111 and the distance value provided by the distance sensor 112; the weight-reducing controller 110 controls the amount of current input to the weight-reducing electromagnet 106 based on the train speed value provided by the speed sensor 111 and the distance value provided by the distance sensor 112.
Each weight-reducing controller controls the current input into the weight-reducing electromagnet according to the speed value, the larger the speed is, the larger the current input into the weight-reducing electromagnet is, the larger the suction force of the weight-reducing rail on a single weight-reducing electromagnet is, and because the four weight-reducing electromagnets are fixed on the bogie of the suspension type monorail train in two rows, the bogie is also subjected to an upward total tension force, the total tension force is increased along with the increase of the current, and the pressure of a rubber wheel on the bogie on a corresponding rail on a rail box girder is smaller at the moment. The opposite situation is as follows: the smaller the speed is, the smaller the current input into a single weight-reducing electromagnet is, the smaller the suction force of the weight-reducing rail on the single weight-reducing electromagnet is, the smaller the total pulling force borne by the bogie is, and the larger the pressure of the rubber wheel on the bogie on the corresponding rail on the rail box girder is.
When the train speed is low, the friction force between the rubber wheel and the rail is needed to drive the train speed to increase, so that in the case, a low-degree weight reduction mode is adopted, the pressure of the rubber wheel on the rail is large, and friction driving is facilitated. When the train is at a high speed, the train is in a state of maintaining the speed or slowly increasing the speed, the friction force between the rubber wheel and the rail is smaller, the running resistance is lower, and the speed is favorably maintained under the condition of low energy consumption.
Each weight-reducing controller can also control the current input into the weight-reducing electromagnet according to the distance value between the electromagnet and the weight-reducing rail, because under the condition of the same current magnitude, the lower the distance value, the greater the attraction force between the weight-reducing electromagnet and the weight-reducing rail, because of the irregularity of the line, in the actual operation process, the distance value between the electromagnet and the weight-reducing rail is not fixed, if the distance value is reduced, the current input into the weight-reducing electromagnet is very large, a fault that a train is sucked up to collide with the weight-reducing rail due to the overlarge attraction force between the weight-reducing electromagnet and the weight-reducing rail may occur, so once the distance value is reduced and exceeds the allowable value, the weight-reducing controller can interrupt the current input into the weight-reducing electromagnet until the distance value is restored to be within the allowable range, and then resume the current input.
As shown in fig. 4, the weight-reducing rail is flat, the cross-sectional dimension is 250mm × 25mm, the length is 1000mm, the cross-sectional dimension of the corresponding weight-reducing electromagnet is 200mm, 125mm, the width of the magnetic pole on both sides is 25mm, the length of the single electromagnet is 1000mm, the material of the weight-reducing rail and the weight-reducing iron is Q235, the cross-sectional dimension of the electromagnet coil filled with copper wires is 100mm × 150mm, the filling rate of the copper wires in the electromagnet is selected to be 60%, the working air gap is selected to be 10mm, the current passing each square millimeter is selected to be 0.4A, 0.8A,1.2A and 1.6A, and the electromagnetic attraction force between the weight-reducing electromagnet and the weight-reducing rail and the corresponding speed and distance under the condition of the weight-reducing currents are obtained through finite element simulation analysis, and the following table is shown below.
| Current (an) | 0A | 0.4A | 0.8A | 1.2A | 1.6A |
| Electric lightening electromagnet suction (ox) | 0N | 1358N | 5435N | 10435N | 13549N |
| Weight reducing electromagnet total suction (ox) | 0N | 5432N | 21740N | 41740N | 54196N |
| Suction conversion (kilogram) | 0Kg | 543Kg | 2174Kg | 4174Kg | 5420Kg |
| Corresponding speed value (kilometer/hour) | 0km/h | 15km/h | 30km/h | 45km/h | 60km/h |
| Corresponding distance value (mm) | ≤8mm | 8mm-10mm | 8mm-10mm | 8mm-10mm | 8mm-10mm |
It can be known from the table that, when losing weight degree, the rubber tyer of being convenient for drives the train through friction mode with higher speed, and along with the increase of speed, the degree of losing weight can increase, is convenient for effectively alleviate the rubber tyer bearing capacity, increases the life of rubber tyer, when the distance value between electro-magnet and the heavy rail that subtracts is less than 8 millimeters, stops to subtract heavy, prevents that the train from being inhaled to subtract on the heavy rail.
From the above table, it can be seen that the maximum weight reduction of 5.4 tons can be achieved under the combined action of four weight reduction devices one meter long. The corresponding 1.6A per square millimeter is conservative current under the condition of considering heat dissipation, and can be increased to about 2A under the condition of fully considering heat dissipation. In addition, if the engineering quality control is good, the working distance can be reduced to 8 mm, so that the suction force is greater, and therefore the maximum weight reduction is only a conservative value.
According to the analysis, the electromagnetic weight reduction mode is adopted, so that reasonable weight reduction can be flexibly carried out according to the running speed of the train, normal acceleration running of the train is guaranteed, the pressure of the rubber wheel is effectively relieved, and the service life of the rubber wheel is prolonged.
