DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diesel engine with a mechanical governor, and more particularly to a diesel engine having a torque-up device.

[0002]

2. Description of the Related Art FIG. 4 shows a prior art of a diesel engine with a mechanical governor. This has the following basic structure as in the present invention. That is, a governor lever 102 pivotally supported on a governor lever pivot 101 is constituted by a spring force input lever 103 and a governor force input lever 104, and the spring force input lever 103 is connected to the governing lever 105 via a governor spring 106. The fuel metering unit 109 of the fuel injection pump 108 is linked to the governor force generating device 107 via the governor force input lever 104 in an interlocking connection.

[0003] A holder 110 is attached to the governor force input lever 104, and a torque spring 1 is attached to the holder 110.
11 and the torque pin 11
3 is projected, and the holder base end wall 115 is protruded.
Receives the torque spring 111, and urges the torque pin 113 in the direction in which the tip protrudes with the torque spring force 116 of the torque spring 111.
The governor spring force 117 of the governor spring 106 and the governor force 118 generated by the governor force generating device 107 cause the torque pin 113 to resist the torque spring force 116. In a state where the protrusion of the torque pin 113 from the holder tip 112 is minimized, the pair of levers 10 is displaced by the unbalance force between the governor spring force 117 and the governor force 118.
3 and 104 are swung together to form the fuel metering section 109.
Is moved in the partial load region 130. The position of the fuel metering section 109 is the rack pin 147.
Identify by location.

The spring force input lever 10
After the fuel restrictor 119 faces the fuel restrictor 119 and the spring force input lever 103 comes into contact with the fuel restrictor 119, the governor force 118 is unbalanced between the governor force 118 and the torque spring force 116 so that the torque pin 113 is protruded, thereby controlling the governor. A configuration is made in which only the force input lever 104 is swung to move the fuel metering section 109 in the torque-up region 123.
Further, the torque pin 113 from the holder tip 112
The width 132 of the torque-up area 123 is set in accordance with the difference between the minimum and maximum protrusion dimensions.

[0005] In a device having this kind of basic structure, the governor force 118 and the torque spring force 116 during partial load operation.
The pair of levers 103 and 104 swings integrally due to the unbalanced force of the fuel metering rack 109 and the partial load area 130.
Move with metering. During full load operation, the spring force input lever 103 comes into contact with the fuel restrictor 119 to move the fuel metering section 109 to the full load position 131. In this case, as in the case of the partial load operation, the protrusion dimension of the torque pin 113 from the holder tip 112 is minimized. During overload operation, the spring force input lever 103
Abuts against the fuel restrictor 119, and the spring force 117 is completely received by the fuel restrictor 119. Therefore, the torque pin 113 protrudes due to the unbalanced force of the governor force 118 and the torque spring force 116, and the governor force input lever Only 104 oscillates to move the fuel metering section 109 in the torque-up area 123 to supply fuel exceeding the amount limited by the fuel limiter 119 to the combustion chamber (not shown) to avoid engine stall.

In the prior art, the holder 11
0 is formed integrally with the governor force input lever 104, and an opening 129 is provided at the base end of the holder 110.
Screwed into the male base wall 115 of the male screw structure into the opening 1
The holder base end wall 115 is fixed immovably by caulking the peripheral wall of 29. Further, a stopper 1 is provided at the base end of the torque pin 113.
25, and this stopper 125 is
It is facing. Therefore, the minimum protrusion dimension of the torque pin 113 from the holder tip 112 is obtained when the spring force input lever 103 contacts the holder tip 112, and the maximum protrusion dimension is determined when the stopper 125 is attached to the holder tip 112. Obtained when contacted.

In this prior art, a torque pin 113 having a different length and a torque spring 111 having a different spring constant are assembled to a holder 110 so that a width 132 of a torque-up region 123 is provided.
And a plurality of types of governor levers 102 having different push loads of the torque pins 113 are arranged, and these are used properly according to the specifications of the engine. When the one provided with the long torque pin 113 is used, the minimum projection dimension of the torque pin 113 does not change, but the maximum projection dimension increases, so that the difference between these dimensions increases.
The width 132 of 23 increases. In this case, the maximum pressing dimension of the torque pin 113 also increases, so that the compression dimension of the torque spring 111 increases. Accordingly, the maximum pressing load of the torque pin 113 also increases.

Conversely, when the one provided with the short torque pin 113 is used, the minimum projection dimension of the torque pin 113 does not change, but the maximum projection dimension of the torque pin 113 decreases, so that the difference between these dimensions decreases. Correspondingly, the width 132 of the torque-up area 123 becomes smaller. In this case, the maximum pressing dimension of the torque pin 113 is also reduced, so that the compression dimension of the torque spring 111 is reduced, and the maximum pressing load of the torque pin 113 is correspondingly reduced.

[0009]

The above prior art has the following problems (see FIG. 4). A torque pin 113 and a torque spring 111 are attached to the holder 110.
At the time of assembling, the peripheral wall of the opening 129 is caulked to fix the holder base end wall 115 immovably, and subsequent adjustment is disabled. Therefore, the width 13 of the torque-up region 123
2 and a plurality of types of governor levers 102 having different maximum pushing loads of the torque pins 113 are arranged, and these are properly used according to the specifications of the engine. In this case, there is a possibility that a different type of governor lever 102 is erroneously assembled to an engine of a predetermined specification. In addition, a plurality of types of governor levers 102
Must be managed, which is one of the factors that complicates parts management.

The width 132 of the torque-up region 123 and the maximum pushing load of the torque pin 113 are uniformly set in advance in accordance with the specifications of the engine. Output characteristics and exhaust gas characteristics differ due to individual differences. For this reason, it is desirable to be able to finely adjust the width 132 of the torque-up region 123 and the maximum pushing load of the torque pin 113 according to the individual difference of the engine while actually operating the engine and checking the output characteristics and the exhaust gas characteristics. In the related art, such adjustment cannot be performed while the governor lever 102 is mounted on the engine, and it is difficult to make the output performance uniform and to cope with exhaust gas regulations.

A first object of the present invention is to provide a diesel engine with a mechanical governor in which after a torque pin and a torque spring are assembled to a holder, the width of a torque-up region and the maximum pushing load of the torque pin can be freely set. An object of the present invention is to provide a governor lever that can be used for a plurality of types of engines having different specifications.

A second object of the present invention is to provide a diesel engine with a mechanical governor, in addition to the object of the first invention, while actually operating the engine with the governor lever attached to the engine and checking the output characteristics and exhaust gas characteristics. An object of the present invention is to provide a device capable of finely adjusting the width of the torque-up region and the maximum pushing load of the torque pin according to the individual difference of the torque pin.

[Means for Solving the Problems]

(First Invention) The first invention has the following basic structure as illustrated in FIG. That is, the governor lever 2 pivotally supported on the governor lever pivot 1 is constituted by a spring force input lever 3 and a governor force input lever 4.
The above-mentioned spring force input lever 3 is operatively connected to the speed control lever 5 via a governor spring 6, and a governor force generator 7 is provided.

One of the pair of levers 3 and 4 constituting the governor lever 2 is provided with a holder 10.
The torque spring 11 is accommodated in the holder 10, the pin tip 14 of the torque pin 13 is projected from the holder tip 12, and the torque spring 1 is fixed to the holder base end wall 15.
1 and the torque spring 13 of the torque spring 11 urges the torque pin 13 in the direction in which the tip protrudes, causing the pin tip 14 of the torque pin 13 to contact the other lever 3, and the governor spring 6 of the governor spring 6 A torque 17 and a governor force 18 generated by the governor force generating device 7 apply the torque pin 13 to the torque spring force 16.
In a state where the protrusion of the torque pin 13 from the holder tip 12 is minimized, the unbalance force between the governor spring force 17 and the governor force 18 causes the pair of levers 3.4 to move. Are rocked together to move the fuel metering section 9 in the partial load region 30 (the position of the fuel metering section 9 in the figure is specified by the position of the rack pin 47). ).

The fuel restrictor 19 faces the spring force input lever 3, and after the spring force input lever 3 comes into contact with the fuel restrictor 19, the unbalance force between the governor force 18 and the torque spring force 16 is generated. By protruding the torque pin 13 by the above operation, only the governor force input lever 4 is swung to move the fuel metering section 9 in the torque-up region 23 so as to be adjusted. The torque-up region 2 corresponds to a dimensional difference 22 between the minimum protrusion size 20 and the maximum protrusion size 21 of the torque pin 13.
The configuration is such that a width 32 of 3 is set.

According to a first aspect of the present invention, there is provided a diesel engine with a mechanical governor having the above-described basic structure, as follows. That is, as illustrated in FIG.
The holder 10 is screwed onto the one lever 4 so that the holder 10 can be screw-adjusted in a direction parallel to the direction in which the torque pin 13 enters and exits. The stopper 24 is provided so that a stopper 25 provided on the pin base end 24 faces the holder base end wall 15.

(Second Invention) According to a second invention, in the first invention illustrated in FIG. 1, as shown in FIG. 2, an adjusting work window 28 is formed on a case wall 27 of a governor case 26 accommodating the governor lever 2. It is characterized in that the holder 10 can be screw-adjusted from the outside of the governor case 26 through an adjusting work window 28.

[0018]

[Action]

(First Invention) As illustrated in FIG. 1A, the minimum protrusion dimension 20 of the torque pin 13 from the holder tip 12 is such that the tip of the torque pin 13 attached to one lever 4 contacts the other lever 3. This is obtained when the levers 3 and 4 approach the limit and push the torque pin 13 to the maximum. Also, as illustrated in FIG.
Is obtained when the levers 3 and 4 are separated from each other, the torque pin 13 protrudes greatly from the holder distal end portion 12, and the stopper 25 contacts the holder base end wall 15.

For this reason, when the holder 10 is adjusted to be screwed in the direction of its tip, the maximum projection 21 does not change, but the minimum projection 20 of the torque pin 13 decreases. Therefore, these dimensional differences 22 increase, and the width 32 of the torque-up region 23 of the fuel metering section 9 increases accordingly. Further, in this case, the maximum pressing dimension of the torque pin 13 also increases, so that the compression dimension of the torque spring 11 also increases, and the maximum pressing load of the torque pin 13 correspondingly increases. As illustrated in FIG. 1A, when the protrusion of the torque pin 13 from the holder tip 12 is minimized, the difference 22 between the minimum protrusion 20 and the maximum protrusion 21 is equal to that of the stopper 25. It is equal to the distance 33 from the holder base end wall 15.

When the holder 10 is adjusted by screwing in the proximal direction, the maximum projection 21 does not change, but the minimum projection 20 of the torque pin 13 increases. For this reason,
These dimensional differences 22 are reduced, and the width 32 of the torque-up region 23 is correspondingly reduced. Further, in this case, the maximum pushing dimension of the torque pin 13 is also reduced, so that the compression dimension of the torque spring 11 is also reduced, and the maximum pushing load of the torque pin 13 is correspondingly reduced.

As described above, the torque pin 1 is
After assembling the torque spring 11 and the torque spring 11, the width 32 of the torque-up area 23 and the maximum pushing load of the torque pin 13 can be freely set by adjusting the screwing of the holder 10, and a single type of governor lever 2 having a different specification can be used. Can be used universally for multiple types of engines.

(Second Invention) The second invention operates as follows in addition to the operation of the first invention. As illustrated in FIG. 2, while the governor lever 2 is attached to the engine, the engine is actually moved, and the holder 10 is screw-adjusted from the outside of the governor case 26 through the adjustment work window 28, whereby individual differences in the engine are obtained. The width 32 of the torque-up region 23 and the maximum pushing load of the torque pin 13 shown in FIG. 1 can be finely adjusted in accordance with the above to adjust the output characteristics and the exhaust gas characteristics.

[0023]

【The invention's effect】

(First invention) The first invention has the following effects. After assembling the torque pin and torque spring to the holder,
By adjusting the screwing of the holder, the width of the torque-up region and the maximum pushing load of the torque pin can be freely set, and a single type of governor lever can be used for a plurality of types of engines having different specifications. For this reason, unlike the case where a plurality of types of governor levers are arranged and used according to the type of engine specification, there is no possibility that different types of governor levers are erroneously assembled to an engine having predetermined specifications. Also,
Since it is not necessary to manage a plurality of types of governor levers, parts management becomes easy.

(Second Invention) The second invention has the following effects in addition to the effects of the first invention. With the governor lever attached to the engine, the engine is actually moved, and the holder is screwed from the outside of the governor case via the adjustment work window to adjust the width of the torque-up area and the maximum torque pin according to individual differences in the engine. It is possible to finely adjust the indentation load and adjust output characteristics and exhaust gas characteristics. For this reason, compared to the case where such adjustment cannot be performed, it is easier to make the output performance uniform and to cope with exhaust gas regulations.

Is assembled. A diaphragm case 40 of a boost compensator is attached to the side of the governor case 26.

The structure of the mechanical governor of this embodiment is as follows. That is, as shown in FIG. 2, the governor lever 2 is of a two-lever type including a spring force input lever 3 and a governor force input lever 4. The pair of levers 3 and 4 are pivotally supported by the governor lever pivot 1 so as to be swingable. Spring force input lever 3 and governing lever 5
And a governor spring 6 is interposed therebetween. An input roller 41 is provided at the lower end of the governor force input lever 4, and the governor force generator 7 faces the input roller 41. The governor force generator 7 includes a fly weight 43 swingably attached to a governor shaft 42 and a governor sleeve 44 slidably fitted to the governor shaft 42. The governor shaft 42 is configured by a rear end portion of an injection cam shaft 45 protruding from the inside of the injection pump case 39 into the governor case 26. A rack interlocking plate 46 is provided between the upper end of the governor force input lever 4 and the fuel metering unit 9 of the fuel injection pump 8. A Bosch-type row pump is used as the fuel injection pump 8, and the fuel metering unit 9 in this case is a fuel metering rack.

A round hole is formed at the front end of the rack interlocking plate 46, and a rack pin 47 of the fuel metering rack 9 is fitted therein. A long hole 48 is formed at the rear end of the rack interlocking plate 46 in a direction parallel to the moving direction of the fuel metering section 9, and an engaging pin 49 is provided at an upper end of the governor force input lever 4 to protrude sideways. The engagement pin 49 is slidably fitted in the elongated hole 48. The fuel adjusting section 9 is urged by a start spring 50 in a fuel increasing direction.

This mechanical governor is provided with a torque increasing device, and its structure is as follows. That is,
As shown in FIGS. 1A and 1B, a holder 10 is attached to the governor force input lever 4, and a torque spring 11 is housed in the holder 10. A torque pin 13 is inserted through the holder 10, and the torque pin 1
The third pin tip 14 protrudes. The pin tip 14 has a larger diameter than other portions, and the torque spring 11 is interposed between the pin tip 14 and the holder base end wall 15,
The torque pin 13 is urged in the distal end protruding direction by the torque spring force 16 of the torque spring 11 received by the holder base end wall 15.

Further, the pin tip 1 of the torque pin 13
Reference numeral 4 denotes the spring force input lever 3, and the torque pin 13 is pushed into the holder 10 against the torque spring force 16 by the spring force 17 of the governor spring 6 and the governor force 18 generated by the governor force generator 7. When the protrusion of the torque pin 13 from the holder tip 12 is minimized, the pair of levers 3 and 4 swings together due to the unbalanced force of the spring force 17 and the governor force 18, and the fuel metering unit 9 is moved in the partial load area 30.

After the fuel restricting device 19 faces the spring force input lever 3 and the spring force input lever 3 comes into contact with the fuel restricting device 19, the torque pin is imbalanced by the governor force 18 and the torque spring force 16. When the projecting portion 13 projects, only the governor force input lever 4 swings, so that the fuel metering section 9 is metered and moved in the torque-up region 23. The width 32 of the torque-up region 23 is set in accordance with the dimensional difference 22 between the minimum projection size 20 and the maximum projection size 21 of the first embodiment.

In the mechanical governor, a governor force 18 is generated by the governor force generator 7 when the engine is operating, and a spring force 17 is generated by the governor spring 6. When the partial load operation is performed, the governor force 18 and the torque spring force 16 are different. The pair of levers 3 and 4 swing together as a result of the balancing force to move the fuel metering section 9 in the partial load region 30. Further, during the full load operation, the spring force input lever 3 comes into contact with the fuel restrictor 19, and the fuel metering rack 9 is positioned at the full load position 31. In this case, as in the case of the partial load operation, the protrusion dimension of the torque pin 13 from the holder tip 12 is minimized.

During the overload operation, the spring force input lever 3 comes into contact with the fuel restrictor 19, and the spring force 1
7 is completely received by the fuel restrictor 19, and the governor force input lever 4 is formed by the torque pin 13 projecting by an unbalanced force between the governor force 18 and the torque spring force 16.
Only the rocker swings and moves the fuel metering section 9 in the torque-up area 23 to supply fuel exceeding the amount limited by the fuel limiter 19 to the combustion chamber (not shown) to avoid engine stall.

Incidentally, as shown in FIG.
Is interposed and interlocked between the rack pin 47 and the engagement pin 49 by the urging force of the start spring 50, so that the engagement pin 49 and the elongated hole 48 do not rattle with each other. Also,
Since the governor force 18 is not generated when the engine is started, the fuel adjusting section 9 is positioned at the start increasing position 51 shown in FIG. 1B by the urging force of the start spring 50, and the engine is started immediately by the increased start. .

In this embodiment, after the torque pin 13 and the torque spring 11 are assembled to the holder 10, the width 32 of the torque-up area 23 and the maximum pushing load of the torque pin 13 can be freely set as follows. A configuration is employed. That is, as shown in FIGS. 1A and 1B, the holder 10 is screwed to the governor force input lever 4. As shown in FIG. 1C, a slit 52 is provided on the base end surface of the holder 10.
By screwing the holder 10 with a tool fitted into the
As shown in FIGS. 1A and 1B, the holder 10 can be screw-adjusted in a direction parallel to a direction in which the torque pin 13 enters and exits.

Then, the pin base 24 of the torque pin 13 projects from the holder base wall 15, and this pin base 24
The stopper 25 of the circlip is externally fitted and fixed to the holder. The stopper 25 faces the holder base end wall 15 and, as shown in FIG. The protrusion of the torque pin 13 from the tip 12 is stopped , and the torque pin 1 from the holder tip 12 is stopped.
3 is configured such that the protrusion dimension is maximized. A flange 53 is provided on the holder base end wall 15, and a loosening prevention spring 54 is interposed between the flange 53 and the governor force input lever 4. Also, the pair of levers
3 and 4 are provided with contact portions 3a and 4a, respectively.
a ・ 4a abut each other and each lever 3 ・ 4 reaches the limit
When approaching, the torque pin 1 from the holder tip 12
3 is configured to minimize the protrusion dimension.

According to such a configuration, when the holder 10 is adjusted to be screwed in the direction of the tip thereof, the maximum projection 21 does not change, but the minimum projection 20 of the torque pin 13 decreases. For this reason, these dimensional differences 22 increase,
Correspondingly, the width 32 of the torque-up area 23 of the fuel metering section 9 increases. In this case, the torque pin 13
Of the torque spring 11
And the maximum pushing load of the torque pin 13 also increases.

When the holder 10 is screwed and adjusted in the proximal direction, the maximum projection 21 does not change, but the minimum projection 20 of the torque pin 13 increases. Therefore, these dimensional differences 22 are reduced, and the width 32 of the torque-up region 23 is correspondingly reduced. Further, in this case, the maximum pushing dimension of the torque pin 13 is also reduced, so that the compression dimension of the torque spring 11 is also reduced, and the maximum pushing load of the torque pin 13 is correspondingly reduced.

In this embodiment, the width 3 of the torque-up region 23 is maintained while the governor lever 2 is attached to the engine.
In order to be able to finely adjust 2 and the like, the following configuration is adopted. That is, as shown in FIG. 2, an adjustment work window 28 is opened in a case wall 27 on the rear side of the governor case 26 that accommodates the governor lever 2.

I have. A bowl-shaped plug 55 is attached to the adjusting work window 28. After the work, the adjusting work window 28 is closed with the bowl-shaped plug 55.

Although the contents of the embodiment of the present invention are as described above, the contents of the first invention and the second invention are not limited to the contents of the above embodiment. For example, in the above embodiment, the holder 10 is attached to the governor force input lever 4, but the holder 10 may be attached to the spring force input lever 3.
