Abstract

PURPOSE:To enable the quick-response constant-speed control of a vehicle driver comprising a Diesel engine, an electricity generator and an electirc motor, by using an electric governor to control the field magnet of the generator in parallel with a maximum-minimum governor. CONSTITUTION:An electricity generator 2 is driven by an engine 1. A rheostat 44 is controlled by a servomotor 45 so that the resistance of the rheostat is minimum when the rotational frequency of the engine 1 is higher than a prescribed level and that the resistance increases as the rotational frequency drops below the level. When the speed of a vehicle has exceeded a set level, an electric overall-speed governor 42 applies a fuel reducing instruction to a fuel control valve 31. When the rotational frequency of the engine 1 is about to become lower than the prescribed level, the rheostat 44 is moved by the servomotor 45 to increase the resistance to reduce the energizing of the field magnet of an exciter 43. Consequently, the output of the generator 2 is decreased to diminish the load on the engine 1 to restore the rotational frequency.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a vehicle powered by a diesel engine.

The purpose of controlling a vehicle is to control the axle output, that is, the rotation speed and torque of the axle (or the same as wheels), which in turn controls the speed and traction of the vehicle. Vehicles must be able to start at any time, travel at any speed, and stop at any time.

On the other hand, the weight of the vehicle varies depending on the amount of cargo and the slope of the route.

Curves, etc. are also constantly changing, and the required force of gravity varies from zero to a huge value at any given time. Vehicles powered by a diesel engine (hereinafter simply referred to as "diesel vehicles")
The diesel engine must be controlled so that it generates an output commensurate with this changing load.The diesel engine control device is called a governor, and there are two types: a maximum low governor and a full speed governor. The 1% A deviation also controls the amount of fuel supplied. The configuration and functions of these will be described below.

(1) Great! Low governor (V, S, governor) is used in combination with a fuel flow control valve called a low governor expansion throttle valve. The throttle valve controls the amount of fuel sent to the fuel injection pump by changing its opening depending on the amount of pull of the suit lever. The amount of pull of the suit lever determines the amount of fuel burned by the carrot. The driver can obtain almost constant torque within the normal rotation speed range by adjusting the amount of pull on the throttle lever depending on the required engine output, and when the load is large for the same position of the throttle lever, The engine speed is low, and when it is small, the engine speed is high.

Like all machinery, diesel engines have a proper usage range, and if the number of revolutions exceeds the upper limit, there is a risk of damage, and if the number of revolutions falls below the lower limit, there is a risk of the engine stopping. The V8 governor is a kind of safety device for this purpose, supplying the minimum amount of fuel necessary to maintain the minimum (idle link) speed regardless of the throttle lever position, and supplying the minimum amount of fuel necessary to maintain the minimum (idle link) speed, regardless of the throttle lever position, and ensuring that excess fuel is not exceeded to prevent the maximum speed from being exceeded. cut. FIG. 1 is a model diagram showing the configuration of a v8 governor. The seven weights 15 are rotationally driven by the engine, and the number of rotations thereof is proportional to the number of engine rotations.

If the engine speed is below the lower limit, fly weight 1
The centrifugal force acting on 5 becomes smaller and succumbs to the pressing force of the lowest speed spring 32, the 7 weight is closed, the sleeve 33 is moved to the left, the idle boat 12 is opened, and the lowest speed is maintained regardless of whether the throttle valve 13 is pressed once. The necessary fuel will be supplied.

On the other hand, when the maximum rotational speed is exceeded, the centrifugal force acting on the flyweight 15 increases and the maximum speed spring 34
It overcomes the sum of the pressing forces of both the minimum speed spring 32 and the lowest speed spring 32, and moves the sleeve 33 to the right to move to the high speed side port).
11 and prevents the engine speed from being exceeded by blocking the flow of fuel through the throttle pulse 7'13 to the injection pump 8. In this way, the V8 gas/() prevents improper handling of the throttle lever. It is a type of safety device to protect the engine from

The high-speed boat 11 is always fully open and closes only when the speed is above the maximum speed, and the idle boat 12 is always fully closed and opens only when the speed is below the minimum speed.

(2) All-speed governor Figure 2 is a diagram showing the operating principle of the all-speed governor. The command from the outside is given by the amount of pressure applied to the regulating pin 18 that presses down the 7-like eight 21. When the rotational speed increases, the centrifugal force acting on the flyweight 21 overcomes the force of the spring 1B and the sleeve 2
2 to the right and throttle the control valve 13 to reduce the fuel supply amount.
Conversely, when the rotational speed decreases, the spring force prevails and pushes the sleeve back, increasing fuel and maintaining the rotational speed. If the spring 18 is pressed more strongly, the spring force increases, the centrifugal force required for equilibrium increases, and the set rotational speed increases. Generally spring 1
The pressing force of 8, that is, the engine's set rotational speed, is continuously changed or set in several steps, and the engine rotational speed is maintained at each set value (referred to as a notch) regardless of the magnitude of the load.
Build a temple. This kind of 6' governor (hereinafter referred to as human S governor:
) actively controls 91 rpm, unlike the V8 governor, so it does not require a safety device like the VS governor.

The control of diesel vehicles and its problems will be explained below. To control the carrot mounted on a diesel vehicle, either the maximum/minimum governor or the full speed governor is used. In vehicles that use a mechanical torque converter or a torque converter with a direct connection stage, the relationship between engine speed and vehicle speed, which should be independent, is determined by the direct connection, which is inconvenient, so the highest and lowest governor must be used (a full speed governor is not possible). ), but in the case of other generators, electric r, or electric type, either governor can be used.'Now, there are three types of power transmission methods for diesel vehicles: electric, liquid, and mechanical. However, no matter which method you use, the end result is that the engine output is controlled to control the vehicle speed.There are generally two types of remote control methods for governors: electric and pneumatic.
In the electric type, 2 to 4 solenoid valves or electromagnets are appropriately arranged, some of these are energized to produce several levels of displacement in the link or plate, and this displacement is controlled by pneumatic, hydraulic, or te to control the throttle lever or the first speed spring of the A8 governor. Although this method is not continuous in a stepwise manner (referred to as a notch), it is simple in structure and there is no delay in remote control, so it is widely used.

On the other hand, in the pneumatic type, a pressure control valve applies air pressure to the membrane plate, and the displacement of the membrane plate is applied to the throttle lever or speed regulating spring to control the engine. Although this method has the advantage of being able to perform stepless control, it is difficult to make adjustments, so it is not common. In the direct control method using links, it is difficult to route the links to control engines that are far away.

With electric or pneumatic systems, when the train is running with the main controller in a fixed position, and the train resistance changes due to disturbances such as changes in route conditions, the running speed changes and the train moves to a new equilibrium point. . If you want to maintain the same speed as before, change the fuel injection amount by changing the notch (vS
Directly when governor.

When using the As governor, the engine speed changes, but since the governor controls the fuel accordingly, it's the same thing.) It changes the engine output, so that the speed remains the same. The route conditions and the size of the traction load vary widely, and it requires great skill to control them optimally.The number of notches is also limited, and the notches that meet all conditions are Since there is no such thing, I drive with a high notch, and when the speed exceeds, I change it to a low notch, and as it gets slower, I change it to a high notch and the 41i degree becomes sawtooth. Even when automatic control is performed, a speed comparator is used to compare the vehicle speed and the set speed, and the notch is raised or lowered according to the difference, so it is inevitable that the speed will become saw-toothed.

In addition, there are times when accurate, constant-speed operation is required while the load changes, such as when pushing up a hang or loading or unloading a hopper, but this requires skill in operation using conventional control methods. .

To solve this problem, we have developed a method to control the diesel engine so that the diesel vehicle can automatically travel at a preset constant speed, regardless of the slope of the route, the radius of the track, or the number of passengers per passenger. The following two or three JL reform measures were first proposed. This will be discussed below.

Figure 3 shows a representative example of the revised plan. In the case of FIG. 2, the full-speed governor 4 is rotated by the engine 1, but the rotation of the wheel 29 is controlled by a gear 24 attached to the tip of the axle 23 and a wire cape N26. It is conducted by gear 25 to drive the control device. In the case of using the full-speed governor in Fig. 2, the engine rotation speed command given by excitation of the solenoid 16 is read as a command for the rotation speed of the wheels 29, that is, the speed of the vehicle, and the O device in Fig. 2 controls the engine rotation speed. You can control the speed of the vehicle in exactly the same way as you did.

The one in FIG. 4 is yet another embodiment of the Kairan proposal. Diesel engine 1, highest and lowest governor 3 and full speed governor 4
The highest and lowest governor 3 (hereinafter referred to as the vs governor) rotates at a constant ratio to the engine crankshaft rotation speed, while the full speed governor 4 (hereinafter referred to as the A8 governor) rotates at a constant ratio of the engine crankshaft rotation speed. A gear 24 is attached to the end of the wire cable 26 and driven through a gear 25 and the like. In other words, the V8 governor 3 rotates at 9 rotations in proportion to the crankshaft rotation speed, and the
It is assumed that the governor 4 rotates at nine revolutions in proportion to the vehicle speed. Suittorpulp 1 controlled by Matajin S governor 4
3 is connected in series with the high speed port 11 of the vS governor and the fuel cutoff valve 14, and in parallel with the idle boat 12, interposed between the fuel tank 10 and the injection pump 80. The above-mentioned various fuel control valves 11, 1
2.13.Whether to install it upstream or downstream from 14,
The position of the above-mentioned control valve should be selected so that its performance is maximized.To set the running speed of the vehicle, use Hiro solenoid 1.
6 is used. When the fuel shutoff valve 14 is closed, the engine stops running regardless of the engine speed during vehicle speed. sornoid 1
Rotate the regulating lever 17 to 4 stages (general Kf stage if the number of solenoids is n) in the example of Fig. 4 by assembling energized and de-energized for each of the 6 wires, and press the regulating spring 18. You can set the speed in 4 stages. The fuel shutoff valve 14 is pressed by the air cylinder 19, and when it closes, it moves suddenly, and when it opens, it throttles 1) 2.
It gradually opens at 0.

The device of the 9th revised plan, which is composed of Tonoyo 5, operates as follows.

(f) Starting the engine When starting the engine, open the shutoff valve 14 fully and turn the starting motor. Since the vehicle is generally stopped, the control valve 1
3 is full throttle. Since the engine itself rotates at a low speed, the high-speed side boat 11 is also fully opened and sufficient S engine is obtained for starting. Also, after Tojin, even if the shutoff valve 14 is closed, the idle boat 1
During the process of maintaining the minimum rotation speed above 0 with the fuel from 2, the vehicle side does not take any load. In other words, if the vehicle has an electric power transmission device (hereinafter referred to as electric type), the main speed breaker is opened. Vehicles with a liquid transmission device (hereinafter referred to as liquid type)
Now, let's drain the oil from the liquid transmission or disengage the clutch.

(b) Taking off When starting K, the load on the vehicle is taken care of by first turning on the main speed disconnector in the case of an electric type, or filling the liquid transmission with oil or engaging the clutch in the case of a liquid type.

At this point, the engine speed is still at its lowest, but wheel rotational force is generated. However, it is assumed that the load characteristics are determined so that the engine load is within an allowable range. When the shut-off valve 14 is opened very gradually by exhausting air from the air cylinder 19 that drives the shut-off valve 14 via the restrictor 20, the engine output gradually increases, and the leather's gravitational force overcomes the starting resistance of the vehicle. The train departs. In this way, the solenoid 16 is energized to accelerate the vehicle to the set speed, and thereafter the vehicle shifts to constant speed running as described in the next section. In addition, instead of using the shutoff valve 14, the high-speed side boat 11 uses the throttle valve l.
It is also possible to have the function of the shutoff valve 140 at the same time.

rl After starting the vehicle at constant speed, the shutoff valve 14 gradually opens, and as the engine output and vehicle traction force increase, the speed also increases.When the commanded speed is reached, the As governor 4's 7th weight 21
The centrifugal force acting on the throttle valve 13 is balanced with the pressing force of the regulating spring 18 to maintain the opening degree of the throttle valve 13 constant. If there is no load fluctuation, the speed is constant and the control valve opening is also constant, but when the load increases due to approaching a slope, the speed decreases and the centrifugal force acting on the flyweight 21 of the S governor 4 decreases. The flyweight collapses due to the pressing force of the regulating spring 18. Therefore, the sleeve 22 moves to the left, and the throttle valve 13 moves to the right, opening to a large degree, thereby increasing the amount of fuel supplied, increasing the engine output and vehicle tractive force, and restoring the speed. On the other hand, when the load decreases, a new equilibrium moment is reached through the completely opposite process described above.During this time, the action of the As governor 4 is similar to that of the general A8. It is exactly the same as Pupana O action.
The V8 governor 3 functions exactly the same as a general VS governor as a safety device that monitors the engine speed to ensure that it does not exceed the allowable range. Inside setting speed is two solenoids 1
4 levels can be selected arbitrarily with 6 excitation combinations. Generally n
By combining these solenoids, a maximum speed setting of f stages can be obtained.

To stop the vehicle, open the owner's circuit breaker using an electric type, or remove oil from the liquid transmission or disengage the clutch to eliminate the load and close the fuel cutoff valve 14 to cancel constant speed control. The vehicle coasts while the engine is idling. You can stop at will by applying the brakes.

Another embodiment of the proposed reform will be explained with reference to FIG. The electric full-speed governor 42 is normally connected to the engine's ring gear 27.
It is used to control the engine speed by converting the rotation of the vehicle into pulses, but in this case, a detection gear 30 and a pickup 28, which rotate together with the wheels 29, are attached to convert the vehicle speed to the engine speed. It is used for vehicle speed control. The control valve 31 is a dynamic flow rate control valve whose opening is controlled by the command voltage and pressure of the electric S governor 42. electric governor 4
2, there are two methods for commanding the set speed: a continuous method using a rheostat, and a stepwise method using electric signals. Figure 0 shows a method using electric signals. This method is already common and well known for electric governors, so a detailed explanation will be omitted here.

Figure 6 further shows the other 0 & Arashi plans.

Install both the diesel engine IK maximum and minimum governor 3 and the electric full speed governor 4;2. The highest and lowest governor 3 is connected to the gear 6 by the crankshaft 5 of the diesel engine 1.
One of the pickups 28 of the electric governor is mounted opposite the ring gear 27 of the engine, and the other pickup 2B is mounted with the speed detection gear 30 attached to the wheel 29.
Install it facing the The writing pickup 2g has only one side set to the electric governor 42 by the changeover switch 38.
shall be selectively connected to. - # care governor 42
The fuel control valve 31 in O is connected in series with the high speed side port 11 of the lowest governor, connected in parallel with the idle boat 12, and placed between the fuel pump 9 and the fuel tank 100. Here, the two pickups 28 do not necessarily have to be the same.

In short, as long as the voltage, frequency, and drum-shaped pulse required by the electric governor 42 can be generated, there is no problem even if the pulse generation mechanism is different.

Now, the operation of the apparatus according to these improved proposals having the above-mentioned configuration is as follows.

The vehicle must be able to run at any speed up to the maximum speed, including stopping.The master controller 35 (hereinafter referred to as mascon) sets the rotation speed of the tank y1 to idling (minimum rotation speed).
Including IIIk high rotation high rotation side, for example, 8 steps or 16 steps of rotation speed are selected and an instruction is given to the 4-air governor 42. This mascon 35 is handled manually by the driver.

The operation handling and equipment operation are as follows.

The stop changeover switch 38 is set so that the pickup 2B facing the 27 is connected to the electric governor 42.

The mascon 35 has an idling speed (for example, 600 rpm)

Convert the toe command (, into voltage to the governor control unit: / ) 37K if5 t) fj Generate a pulse to the oscillator in the A na control unit 37. On the other hand, a pickup 28 facing the ring gear 27 of the engine generates one pulse when a tooth passes in front of the pickup. That is, the number of teeth of the ring gear 27 is set to 2. When the tank rotation speed is nt□P1, a pulse of A H is generated. compares five and h, ft
>f, the opening degree of the fuel control valve 31 is increased; when f-9, the WI degree of the control valve 31 is maintained as it is; Adjust the utT radiation amount to about 60Orpm@jI! It works to maintain the idling speed of the engine. In addition, the load circuit is open and the generator 2 is idling, so the vehicle is no longer available.

β During departure and acceleration When the circuit breaker (hereinafter referred to as L1) is closed at the time of departure, traction force is generated, the load on the engine increases, and the engine speed decreases. 9. That is, n is small. Nine - become smaller. Therefore, the control valve 31 opens and the fuel injection amount increases, increasing n to 9-fl. If the driver raises the master controller 350 notches, the output voltage of the speed control unit 36 will change and the oscillation frequency of the governor control unit 37 will change.
, -f, and the control valve 31 further moves -<.

ζ Utter Mascon 3! It is possible to set an engine rotation speed that is the same as or less than the number of notch stages of S. Note that if the load increases or decreases due to some disturbance while the engine is operating at a constant rotational speed, a difference between fl and #- will occur even if the engine rotational speed n decreases or increases. At this time, the fuel control valve 13
is automatically controlled by the governor control engine to adjust the fuel injection amount and return to the original rotation speed.

The above is the operating element of the electric full-speed governor that is already publicly known. 0 When performing constant-speed automatic control, for example, when loading and unloading in a hopper or when pushing up a hanger, the load fluctuates during running. Therefore, if the mascon 350 notch is kept constant and the engine speed is constant, but the vehicle speed changes. .

The train starts and accelerates using the method described above, and when the speed approaches 1/h, switch to 9-. At this time, I was driving at vk/h,
If the wheel diameter is d14, and pulses are generated as the wheel rotates, the governor control unit 37f, which receives the governor j, and 9 are compared to automatically control the fuel so that f11I119 is obtained. /h to Vhl k K accelerate. ζThis allows the vehicle to run at a constant speed of Vb/h.

Conversely, don't try to run at a constant speed of vEm/h. n is the engine rotation speed at the corresponding mascon 350 notch. For example, n = 600.800, 1000.1200.14

is necessary. That is, if a pulse generator that generates 1130 pulses per rotation or a detection gear 3o with 1130 teeth is directly connected to the axle end of a wheel 29 with a diameter of 1 m, when the notch of the mask controller is placed at 1 notch (600 rpm), v w 10
The vehicle automatically runs at a constant speed of I regardless of the load.

Also, if you turn the notch to 2 notches, it will run at a constant speed of x13.3*/h. Similarly to the 3-notch and 4-notch modes below, when leaving automatic operation, if the company changeover switch 38 is switched to the engine side pickup 28 side, it is possible to return to general manual operation at any mascon control notch.

During automatic constant speed driving, the vehicle speed is controlled, but the engine speed is not directly controlled, so for example, if the current speed is too slow compared to the set speed, the vehicle may reach full throttle. However, if the load is small at this time, there is a risk that the engine will overspeed. On the other hand, there is a risk that the control valve 31 will be over-throttled and the engine will stall, but in such a case, the maximum/minimum governor 3 is useful to keep the rotation speed above the minimum rotation speed and below the maximum rotation speed.

Figure m7 shows the case where a rheostat is used for the mascon and speed control unit. A stepless full-speed governor that continuously controls the engine speed from the lowest rotation speed to the highest rotation speed is already available on the market, but the example shown in Figure 517 uses this rheostat 39, and it can be adjusted to the lowest rotation speed of the carrot. Constant speed operation is possible at any intermediate speed between the corresponding speed and the speed corresponding to the maximum rotational speed.

(Not in stages) Figure 8 shows a case where one rotational speed is converted into an electrical pulse for detection.・・・・・・2
It works to double the amount.

This is a device that receives one wave and generates two waves.
By stacking R12 stages, ..., n stages, it can be doubled, quadrupled, ..., doubled. Such electronic device extensions are already commercially available. ζThis electronic device is the product! ! Let's call it Ruchiptsiya 0 For example 2
If the multiplier is used, the frequency of the 4m pulse sent to the governor control unit 21 will be twice as high as that without the multiplier. This means that the pulse frequency is the same at the actual speed of 1/2 for the same setting value, that is, it is balanced, and by intervening a 2x multiplier, the setting A degree can be reduced to 1/2. It becomes possible to do something. Therefore, if the master controller can command 8 different engine speeds during manual operation, 8 high speeds are possible without a multiplier during automatic operation, and 8 low speeds are possible with a multiplier, so a total of 1! Steps and +1 all at once
! □Increase. In an actual diesel engine, the engine speed at the highest notch is about three times that at the lowest notch, so with a 1-stage multiplier (i.e. 2x), a low notch with a multiplier and a glayer is about the same as a high notch without a multiplier. Since the pulse frequency is the same, that is, the vehicle speed is the same, and the pulse frequency is the same, it is practically effective to eliminate the duplication by increasing the number of pulses to two stages, that is, four times as many, instead of one stage. In this embodiment, a selector switch 41 in FIG. 8 is used to allow nine transmissions without passing through the multiplier 40. becomes. In addition, by not providing the changeover switch 41 and always connecting the multiplier and wire 40, it becomes possible to use a pulse generator that generates a small number of pulses per rotation, so the set speed can be adjusted by combining the multipliers. There is an advantage that the number of types of A pulse generators can be increased and the number of types of A pulse generators can be reduced to meet the demands for many setting speeds.

In the above explanation, a controller similar to a full-speed governor has no essential difference between a mechanical governor using flyweights and an electric governor using pulses. If you replace it with a clutch, you can use a mechanical governor.

According to the method described above, stepless, smooth, and quick-response automatic constant speed control, which is conventionally necessary and does not require highly skilled drivers, can be achieved by simply adding equipment. All of these necessary additional parts are well-developed, but when used in a different way, they can perform completely new functions, and their operation exceeds the engine's usable speed range under any conditions. It can be used safely without any problems. However, these methods also have 4. There are problems described below. That is, when the vehicle speed exceeds a set value during constant speed operation using the device shown in the RGS chart, the fuel control valve 31 is throttled.

Since there is an idle baud) 12, the engine speed does not fall below idling, and if the load on the vehicle is smaller than the engine output (or main generator output) at the idling speed, the speed of the vehicle will increase. ”.

The present invention aims to improve in what respects.

FIG. 9 shows an embodiment of the present invention.

High speed side port 11 and idle port 12 are in parallel.

The control valve 31 is connected in series with these. In addition, like a general automobile governor, the throttle valve is connected in series to the high speed 111 port. When it is in parallel with the dollar port, keep it fully open. According to this device, even if the opening degree of the control valve 31 is excessive compared to the engine load, overspeed is prevented by the action of the high-speed side port 11. On the other hand, when the vehicle speed is above the set value, the electric full-speed governor 42 throttles the valve 31. If the valve 31 is a valve that supplies enough fuel to maintain the idle link even when the valve is at its minimum opening, it will have a poor response to the governor command to reduce the rotation speed, and it will become fully closed.) If.

The engine may stall before the vehicle decelerates due to inertia. FIG. 10 is an example of a circuit diagram of a generator driven by the engine 1. The engine rotation speed is controlled by the servo motor 45 of the male tuft 44, for example, 60.
When the rpm is higher than 0 rpm, the resistance value is the highest, at J\.

It is assumed that the value becomes larger as it decreases from soorpm.

When the vehicle speed exceeds the set value, the electric full speed controller sends a command to throttle the fuel to the fuel control valve 31.The engine speed decreases, but the vehicle's speed does not decrease due to its large inertia. When the engine speed is about to drop below 60 rpm, the rheostat 44 is moved by the thermostat 5, the resistance value increases, and the field of the exciter 43 becomes weak. Without repairing the engine, the load on the engine is reduced, the rotational speed is restored, and a stoppage is avoided.Another advantage of this method is that the desired purpose can be achieved without modifying the fuel pump, which can be said to be the heart of the engine.
