Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a control device for an internal combustion vehicle that compensates for the axle load of the vehicle by controlling electric auxiliary equipment such as a radiator fan and an electric air compressor. [Prior Art] In recent years, as a countermeasure against internal combustion engine failures, a method has been developed in which an internal combustion vehicle is equipped with two internal combustion engines, and even if one internal combustion engine fails, the other internal combustion engine continues operation. Common. As shown in Japanese Utility Model Application Publication No. 53-66703, such internal combustion vehicles use two internal combustion engines to power two main generators, and from these main generators to a group of main motors. The supplied current is controlled to compensate for the vehicle's axle load.

[Problem to be solved by the invention]

However, in the above-mentioned conventional technology, since electric auxiliary machines such as an engine cooling radiator fan and an electric air compressor are also used separately for each internal combustion engine, the relationship between the electric auxiliary machines is not considered. The disadvantage is that axle load compensation must be performed using complicated current control.

In addition, the number of electric auxiliary machines and devices for controlling the electric auxiliary machines increases, which reduces the effective space within the vehicle and increases the weight and cost of the vehicle.

An object of the present invention is to provide a control device and method for an internal combustion vehicle that can perform axle load compensation through simple control and simplify the configuration of electric auxiliary machinery.

[Means to solve the problem]

” - In order to achieve the above object, the present invention provides an internal combustion vehicle in which two internal combustion engines are mounted, one on each bogie, in which a vehicle is selected from among the two internal combustion engines in conjunction with the traveling direction of the vehicle. The internal combustion engine is equipped with means for driving electric auxiliary equipment or charging the battery.

Further, the present invention provides a method of installing two internal combustion engines, one on each truck, connecting an auxiliary generator to each of the internal combustion engines, and electrifying each of the auxiliary generators by the internal combustion engine. In an internal combustion vehicle that supplies power from an auxiliary generator to an electric auxiliary machine, a battery, etc., the output of the auxiliary generator is controlled to a constant voltage output or a constant V/f ratio output, and is linked to the traveling direction of the vehicle. ,
Means for selecting either the constant voltage output or the constant V/f ratio output is provided.

Further, the present invention provides an internal combustion vehicle in which two internal combustion engines are mounted, one on each bogie, of the two internal combustion engines,
A radiator fan connectable to either internal combustion engine is provided, and a means is provided for electrically driving the front radiator fan by the selected internal combustion engine in conjunction with the direction of travel of the vehicle.

Further, the present invention provides an internal combustion vehicle in which two internal combustion engines are mounted on each truck, and a radiator fan is connected to each of the internal combustion engines, in which one of the radiator fans is linked to the traveling direction of the vehicle. The system is equipped with a means for stopping the engine.

Furthermore, the present invention provides a method for driving an internal combustion vehicle in which two internal combustion engines are mounted, one on each bogie, by switching one of the two internal combustion engines in conjunction with the traveling direction of the vehicle. The internal combustion engine is used to charge the electric auxiliary equipment or the battery.

[Effect]

According to the above configuration, the selected internal combustion engine charges the battery that drives the electric auxiliary equipment in conjunction with the traveling direction of the vehicle, so the output of the internal combustion engine is reduced, and the traction power of the two internal combustion engines is reduced. A difference occurs in the output, and axle load compensation between the bogies can be performed.

In this case, two auxiliary generators are each driven by two internal combustion engines in order to charge the rechargeable battery that drives the electric auxiliary equipment. When charging the battery with the output from the auxiliary generator, the output is controlled to a constant voltage output, and when the output from the auxiliary generator is used to drive the electric auxiliary equipment, the output is controlled to a constant V/f ratio output. control. Whether the output from the auxiliary generator is a constant voltage output or the V/f ratio -
There is a difference in the traction power of the internal combustion engine depending on whether it is a constant output or not. This allows axle load compensation between bogies.

In addition, when driving a radiator fan as one of the electric auxiliary machines, the output of the internal combustion engine that drives the radiator fan of the two internal combustion engines is reduced, so the axle load between the bogies is It becomes possible to provide compensation.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a control device for an internal combustion vehicle according to the present invention. In the figure, internal combustion engines 1 and 2 drive main generators 3 and 4, respectively, and main generators 3 and 4 generate electric power.

The power causes the main motor group 5.6 to rotate. The main motor groups 5 and 6 are respectively attached to the trolley, and the main motor groups 5 and 6 are respectively attached to the truck.
The vehicle advances by the rotation of 6.

Each internal combustion engine 1.2 also drives an auxiliary generator 7.8, which outputs electrical power.

This output is output from the field control device 9. When controlled by lO, a constant voltage output is obtained, and when controlled by one or 12 field control devices, a constant V/f ratio output is obtained. Field control devices 9 to 12
are operated by turning on the contactors ↓3 to 16, respectively.

The output from the auxiliary generator 7 can be supplied to an electric air compressor (3-phase induction motor) 21 and a storage battery 25 via contactors 17, 19, respectively, and the output from the auxiliary generator 8 can be supplied to the contactors 18. 20 to an electric air compressor 21 and a storage battery 25, respectively (the electric air compressor 21 may be an electric radiator fan). Which of the electric air compressor 21 or the storage battery 25 should be supplied?

It is involved in switching the contactors 17-20.

The storage battery 25 is used for starting the internal combustion engine and as a control power source (not shown).

Also, the air clutch 23.
By operating 24, driving force is transmitted to the radiator fan 22 from either one of the internal combustion engines 1 and 2.

In other words, when the bogie of the main motor group 5 is in the forward direction (on the front side with respect to the traveling direction of the vehicle), the air clutch 2
3 is connected and the radiator fan 22 is driven by the internal combustion engine 1 , and when the truck of the main motor group 6 is in the forward direction, the air clutch 24 is connected and the radiator fan 22 is driven by the internal combustion engine 2 .

On the other hand, the outputs from the auxiliary generators 7 and 8 are controlled as follows. That is, when the bogie of the main motor group 5 is in the forward direction, the contactor 15 is turned off and the output from the auxiliary generator 7 becomes a constant V/f ratio output by the field control device 11, and this output is output from the contactor. 17 to the electric air compressor 2]. At the same time, the contactor 14 is turned on, and the output from the auxiliary generator 8 becomes a constant current output by the field control device 10, and this output is supplied to the storage battery 25 and the control power source via the contactor 20. Further, when the carriage of the main motor group 6 is in the forward direction, the contactor 13 is turned on and the output from the auxiliary generator 7 is controlled by field control'! A constant voltage output is obtained by the A position 9, and this output is supplied to the storage battery 25 and the control power source (1) via the contactor 19.At the same time, the contactor 16 is turned on, and the output from the auxiliary generator 8 is connected to the field control device. 12
This results in a constant V/J ratio output, and this output is the contactor 20
The electric power is supplied to the electric air compressor 21 via the power source and 19.

In addition, in the figure, the code 26 is a contactor, and the codes 27 to 29 are
is a rectifier, and 30.31 is a switch.

In the above control state, the main filtration from the main generators 3 and 4
Figure 2 shows the output status to the 1iIJ aircraft groups 5 and 6. Second
The figure shows the output characteristics of the main generators 3 and 4 when the horizontal axis is current 1d and the vertical axis is voltage Ed. In this case, the vehicle is moving in the direction in which the bogie of the main motor group 5 is moving forward.

The hyperbola P□ represents the output from the main generator 3 that is supplied to the main motor group 5, and the hyperbola P2 represents the output from the main generator 4 that is supplied to the main motor group 6. Hyperbolic i! P,
,,P, and the induced voltage of the main motor groups 5 and 6 with φV, at a certain speed V of the vehicle, the output from the main generator 3 and the output from the main generator 4 have a current difference ΔId. I can see that it is happening. This means that by reducing the torque corresponding to the current difference ΔId on the front bogie with respect to the vehicle traveling direction, it is possible to reduce the axle load shift occurring on the rear bogie.

Therefore, by selecting the internal combustion engine that drives the electric auxiliary equipment in conjunction with the direction of travel of the vehicle as in this embodiment,
It is possible to provide a difference in the traction outputs supplied to the main motor groups, and it becomes possible to reduce the axle load shift between the bogies of the vehicle.

Next, a case will be described in which one of the two internal combustion engines stops. In FIG. 1, for example, the radiator fan 22 is electrically powered via the clutch 23, the auxiliary generator 7 is electrically operated via the contactor 17, and the electric air compressor 21 is activated via the contactor 17. storage battery 2
5 is charging. If the internal combustion engine 1 stops in this state, power cannot be supplied to the electric air compressor 21,
There is a risk that the pressure in the air brake system will drop. Therefore, the contactor 14 is opened, the contactor 16 is closed, the field control device 12 outputs a constant V/f ratio, and the contactor 16 is turned on.
0 and 18 and the air compressor 21 is electrically operated, the pressure of the air brake system can be maintained at a predetermined value. At this time, control power for the vehicle is supplied by the storage battery 25.

According to this embodiment, by providing the auxiliary generator with two functions: constant voltage output and constant /J ratio output, it is possible to provide redundancy to the power supply to the electric auxiliary equipment and improve the operating rate of the vehicle. I can do it.

〔Effect of the invention〕

As explained above, according to the present invention, the electric auxiliary equipment is activated by the internal combustion engine selected in conjunction with the direction of travel of the vehicle, so that the axle load of the vehicle can be compensated with simple control. becomes possible.

Furthermore, since the configuration of the electric auxiliary equipment is simplified, the right movement space in the vehicle becomes wider, and it is also advantageous in terms of cost.
