It relates to a diesel engine mounting structure. Single-rail carriages
Load on one rail laid in the mountains and hills
It is a device that automatically travels on a car. Originally originated in Ehime
Designed for transporting tangerines, fertilizers and agricultural tools in tangerine orchards
Things. A small load with a load of about 250kg
A small truck was connected to the rickshaw. For later
Used for agriculture to transport fertilizers and products
Sometimes. In addition, heavy goods such as stones, cement, and gravel are transported.
Sometimes used for civil engineering purposes. In that case the truck
A large capacity of 1 to 2 tons is required.
A pair of upper and lower rails because there is no single rail
Use alignment. In the case of the applicant's device, in the case of one rail
The rack is on the side and the side drive
It is in mesh with the pinion. This is common to all
You. [0003] The drive source has been a gasoline engine
There were many. For things that use an engine, lay wires and cables
There is no need to lay along For a remote mountainous area
I have. However, use of the engine has limited power and operability
Is not good, electric single-rail carriers are also manufactured and used
Sometimes. If you use electricity, you can use various electronic circuits
It can be started and stopped easily. [0004] The applicant of the present invention has
And the thing of the electric motor has been manufactured. This time diesel
I want to make something for an engine. The present invention is a Dize
New engine driven single-rail carrier with a new engine
It is intended to provide a mounting structure. [0005] A single-rail vehicle is composed of a motor vehicle and a vehicle.
You. In the case of an engine drive, the powered vehicle is driven by the engine
Be moved. The fuel is gasoline mixed with lubricating oil. 2 sa
The vehicle is equipped with a cycle gasoline engine. Ray
Is a 50 mm square pipe. Up, down, horizontal
Where the rack is welded. The applicant's single-rail carrier is
The rack is on the side. Powered vehicles are engines, clutches,
Gear reduction mechanism, brake, upper wheel, lower wheel, pinion,
It has an oil tank and a manual operation lever. engine
Slow down the rotation and turn the pinion. Pinion rack
Push the reaction car to move. The transport vehicle is loaded with luggage
And they do not move. Towed by motor vehicle. [0006] The single track transportation which has been manufactured by the present applicant so far.
The driving source for the truck was a gasoline engine or electric motor. Ke
For small single-rail vehicles where cables cannot be laid.
It was a gasoline engine. Two-cycle gasoline engine
It is a gin and the whole device is easy to make small and light
No. Therefore, the price of the motor vehicle can be reduced. Initial investment
It has the advantage of being cheap. The fact that powered vehicles are lightweight
This is an advantage for single rail vehicles. However, gasoline engines have disadvantages on the other hand.
You. One is that fuel is expensive. Unlike passenger cars
The two-stroke gasoline engine of a single rail vehicle is gasoline
Fuel mixed with lubricating oil in addition to phosphorus is used as fuel. Scorpion
Lubricating oil mixed in a ratio of 1 to 20 to 25
Oil). Without lubricating oil, engine burns
Cause injury. Lubricating oil is expensive, pushing up fuel costs
You. For example, if only gasoline is 90 yen per liter
Even a mixed oil containing lubricating oil costs as much as 120 yen per liter.
Become. There is also a management problem. Do not use for a while
Gasoline and lubricating oil are 2
Separates into layers. Then only the lubricating oil that has accumulated underneath
The engine is started by being sucked into the carburetor (carburetor)
become worse. Sometimes it doesn't turn. Gasoline and lubricating oil
Engine that does not send fuel mixed with oil to the engine
Is required. Worse, the two-stroke engine is cold
Mixed oil (a mixture of gasoline and lubricating oil)
Takes heat when passing through venture of carburetor
The carburetor freezes and the mixed oil stops
The two-stroke engine stops immediately. [0009] Two-stroke gasoline engines are still large
Problem. The spark plug quickly becomes dirty and
It is possible. Remove frequently and clean
There must be. When you hurry up the mountain
Start with cleaning the plug and adjusting the gasoline.
I can't go. This is very troublesome. Maintenance
A single-rail carrier that requires no nonce and can be started immediately is desired.
You. Therefore, the applicant of the present invention has proposed a diesel engine.
I decided to build a rail truck. Diesel engine
If a gin is used as the drive source, there is no spark plug
No need to clean the rugs. Even in cold weather, the engine
Use diesel engines and use light oil as fuel
You. Liquid phase separation is troublesome because no fuel containing lubricating oil is used
Not at all. Light oil is less volatile than gasoline
Therefore, it moves immediately after being left for a long time. this is
It is very convenient. No daily maintenance required
Thank you. It also saves fuel economy itself. Dee
The Zell engine uses light oil. Diesel oil is cheaper than gasoline
There is no need to mix lubricating oil. For example, one liter of mixed oil
Even if it is 120 yen, light oil is about 70 yen, so fuel
Cost can also be reduced. SUMMARY OF THE INVENTION Problems to be Solved by the Invention
A good thing about a single-rail carrier is this
It is. However, the present inventor has
There is a good reason not to make something. One
Mari diesel engines also have drawbacks. It
Means that the diesel engine is heavy. gasoline
The engine itself is heavier than the engine. Then the structural materials
It has to be stronger and heavier. In fact, two
The cycle gasoline engine is a light one of about 30kg.
However, the diesel engine weighs 47 kg. Heavy
This is a disadvantage of diesel engines. [0012] A single rail carrier has one (or two) thin rails.
-Run slowly on the rails, but
Load, load applied to the engine,
However, it is desirable that the motor vehicle be lightweight. Lightweight
For example, use a frame made of Al alloy instead of cast iron.
You are. Powered car when it comes to using diesel engines
It is not desirable because it becomes heavy. [0013] It is the total weight,
The engine itself is heavier than the
Attachment of the body to the motor vehicle becomes a problem. Heavy diesel
Since the engine is fixed, it will be horizontal from the frame
Take out the metal support plate, place the engine on it and fix it
It is possible that. In addition, the output shaft and
Connection with the first stage gear shaft of the transmission (gear transmission mechanism)
And the side of the engine and the gear transmission on the side of the cover
It is conceivable to fasten the wall with bolts. I mean
For example, take the engine at two places, the bottom and the side.
It is an attachment mechanism. The support plate extending laterally from the frame
Most of the weight of the gin is applied, and the remaining force is applied to the top of the frame
It is a double support structure that hangs. Frame below
Connected to the rail by wheels, upper wheels, and drive pinions
And the weight of the engine is railed through two paths
It will be transmitted to. That sounds good
U. The load is supported doubly, so I just receive it from below
So it should be safe. However, this is not the case. Frame
Shaft barrel including support plate extending from the side and input shaft extending from above
The distance is too large, so the dimensional accuracy is poor.
If you tighten the bolt, the other bolt will not tighten properly
I will be. Accumulation of errors such as frame and mounting plate
But the integration error is large and the engine cannot be mounted properly.
No. That is not all. Although there are two mounting mechanisms,
Vibrates up and down, left and right or diagonally because of heavy weight. So
Modes of vibration of two are different and unique to the two support paths
The frequency of vibration is also different. Therefore, independent vibrations occur.
As a result, extra force is applied to the other support mechanism. Was
Failures such as loose bolts or cracks in the support plate
Get offended. Even if it does not lead to a failure, the noise is extremely loud
It is harsh. As described above, in a single-rail carrier, a heavy engine is used.
It is difficult to support Jin. Such a problem
On the other hand, the inventor once supported the engine only from the side.
Some have invented a mechanism. Japanese Patent Application No. 63-146053 (Japanese Unexamined Patent Publication No.
No. 2) "Engine mounting structure of single rail carrier"Applicant;
Gusa Cableway Co., Ltd., the inventor; Hideo Chikusa
The engine output shaft is connected via a centrifugal clutch.
Only the surrounding flange and the centrifugal clutch flange
Is proposed with bolts. Engine
Sorin engine. This is the engine
It is a cantilever. That is, the bottom support plate is omitted from below.
Does not support the engine. Support machine
Two vibration modes are combined because the structure becomes one
That's not to say, low vibration and low noise
There was such an advantage. "… The engine is equipped with a centrifugal clutch.
Only the part is fixed to the frame ... "
The features are described as follows. Because there is only one mounting path
The accuracy comes out. Bolts for accurately attaching the engine
Is less likely to be loosened and the bolt broken. in addition
Noise is also reduced. Less damage to the engine support
It is. This is, however, an issue for gasoline engines.
It is an attached structure. Mounting mechanism for diesel engine
And there is still no suggestion. As a drive source for single rail vehicles
I didn't use a diesel engine.
You. Special measures are required because they are heavier than gasoline engines
It is. According to the present invention, there is provided a single-rail carrier comprising:
Powered vehicles are gear reduction mechanisms in which the power transmission mechanism is a gear train
The engine is a diesel engine and the centrifugal
Cylindrical part for incorporating clutch and bolt fixing
An engine mounting flange having a flange portion and a leg, and a leg
Engine mount that is connected to the engine mounting flange by
Diesel engine
Fix the engine bottom and lower side
Insert the centrifugal clutch into the cylindrical part of the
The flange of the transmission case to the side of the transmission case
With the diesel engine on the side of the mission case
It is characterized by being cantilevered. The engine is directly connected to the side of the frame.
Where a special member called an engine mounting member was used
There is a feature. Diesel engine is gasoline engine
Because it is heavier than
You. The engine mount carries the bottom of the engine. Engine
The mounting bracket is connected to the engine mounting flange with screws?
The load on the engine mount is
The gravity and bending moment going down
appear. The engine mounting flange itself is the engine
The engine is also held at the bottom and side
Is held in. Therefore, only the side is the holding mechanism
Are more stable than those that support In this regard,
JP-A-63-146053 (JP-A-1-314662)
And different. BEST MODE FOR CARRYING OUT THE INVENTION
There are some issues with switching to diesel engines
The engine mounting structure also requires some contrivance. Gaso
The mounting structure should be more solid because it is heavier than the phosphorus engine
There must be. Therefore, the present invention provides, for example, ductile
An engine mounting member made of cast iron is used. This
This is a device to support the lower and lower sides of the engine.
You. It is unsuitable to hold heavy engines only on the sides
Also supports the bottom. The load can be supported by it, but only the lower base
The roll is remarkable when holding. I want to suppress the roll to some extent.
Is also held by the engine mounting member. In short, the engine
The mounting members support the lower two parts of the engine to prevent rolling
However, it does not completely prohibit rolling. engine
The mounting member itself is somewhat elastic and this is distorted.
To attenuate the roll. Frame with damping roll
To reduce the amplitude of the frame itself.
You. The engine mounting flange has a centrifugal clutch inside.
It is also a part to store. Engine mounting flange is engine
An important role for retention, but the
There is also a role as a source. Engine mounting flange is centrifugal
It has a cylindrical portion for receiving the latch. The cylindrical part is simple
More resistant to load and better tolerating bending moments
Therefore, it is a preferable structural material. Engine mounting flange
In addition, a flange (square flange)
Flange or circular flange). Screw the flange
Screwed to the side of the frame by the child. By itself, a strong shearing force is applied to the screw.
I will. So, on the frame side ahead of the engine mounting flange
An insertion tube portion that fits into the opening of the surface is provided. Insertion
Insert the cylinder into the frame opening and screw it with a flange.
When stopped, the insertion tube bears the shearing force. Bolts for
No shearing force is applied. It is only a pulling force. bolt
Is strong against pulling and can hold engine load. In mounting the engine on the frame
And cantilever the engine on the side of the frame. Engine
The mechanical stability is increased because the position of the bearing is lowered. Ray
The transmission case on one side and the engine on the other side
There is a balance. Rolling because the engine is low
The moment becomes smaller. Engine on frame
Even when you put it on, it balances the left and right moments
However, the moment generated by the roll is large. Rail
Is also curved, the outward moment increases.
So the possibility of falling is high. That is, it becomes unstable. At the position of the centrifugal clutch,
Since the engine mounting member is connected, the centrifugal clutch and reduction gear
Structure can be directly connected. Loss of torque due to direct connection
There is no. There is no need for repair. Conventional single-rail carrier
Uses a belt and pulley to connect the centrifugal clutch and the speed reduction mechanism.
I was going. Do not cover the belt / pulley mechanism.
There is also a drawback that you have to go to the side. Belt slip
There is a loss due to The belt transmission efficiency is about 0.9
It is about 0.98 when directly connected. More belt pooh
The mechanism must be replaced due to belt wear.
Belts cannot be changed by an amateur. Must be an expert
It is troublesome. The present invention can directly connect the engine and the speed reduction mechanism.
Therefore, belt pulleys are unnecessary. Why is the direct engine connection type possible? When
Because the engine is supported on the side of the frame
It is. If you bring it on the frame, it will be a belt
・ The pulley must be connected. DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, the entire structure of a single-rail carrier is explained.

The four bolts 97 have different power distribution between the upper bolt and the lower bolt.
Become. A strong tensile stress is always applied to the upper bolt. under
Bolt is subject to tensile stress generated during tightening
You. Diesel engine cantilever at the centrifugal clutch part
Supported. Clockwise (clockwise) rotation in FIG.
The rolling moment is applied from the engine side to the centrifugal clutch.
Use. The transmission case counterclockwise counters that
A moment is applied to the engine mounting flange 42.
Running on the rails causes the engine to swing left and right.
Move. The vertical vibration of the engine is the
1 causes expansion and contraction. Engine mounting member 41
Of the transmission case will bend to the left and right
Causes vibration. Engine mounted components are ductile cast
This is because iron and other materials with excellent vibration damping properties are used.
Transmission of vibration to the transmission case can be softened.
Wear. As described above, the present invention can be used as a drive source for a motor vehicle of a single-rail carrier.
Until then, two-stroke gasoline engines and motors were used
Have been. Motor lays wires and cables along rails
Must. Good for large, passenger single-rail vehicles
Suitable. It is a small single-rail carrier,
About, can pull power cable due to economic conditions
If not, powered by a two-stroke gasoline engine
Was to be driven. 2-cycle gasoline engine
Gin is small and lightweight. Light as a whole device
No. Due to such advantages, so far two cycle gas
I was using a Sorin engine. But two cycle scorpion
Engine maintenance was troublesome. Use for a week
If not used, the mixed oil will separate and the engine will start poorly
Or carburetor nozzles are clogged
And the spark plug becomes dirty and must be cleaned.
Did not. The present invention uses a diesel engine as a drive source.
Used. It doesn't get dirty because there is no spark plug
Need not be repaired. Do not separate layers because no oil mixture is used
No. Even if you don't use it for a few days, it won't go wrong. So me
No need for maintenance.
There is a point. When a diesel engine is used, the fuel is light oil.
As a result, fuel costs can be greatly reduced. Mix oil with gasoline
Lubricating oil mixed, but high in lubricating oil. Also in that respect
Are better. However, the diesel engine is gasoline
Because it is heavier than the engine, the whole device is heavier.
Hold heavy objects just above the support frame
It is common sense to do. However, the present invention is not so. Departure
Akira framed the diesel engine at the centrifugal clutch.
The cantilever is supported on the side of the system. Here alone
Therefore, the mounting accuracy is good. Attach at multiple locations separated
If so, the accuracy will be worse. Vibration because it can be installed in one place
Has only one mode. The vibration mode is simple,
The mosquito is absorbed by the engine components, so noise is reduced
You. Since the engine is mounted on the side,
Increased mechanical stability. Right and left
You. With a low center of gravity and a structure that can withstand rolling and bending well
is there. High safety. The engine shake is the engine mounted part
Although the material is distorted, the present invention is flexible and dampens vibration.
Wear. The vibration transmitted to the frame becomes much smaller. When the vehicle body shakes vertically, the engine also shakes vertically.
However, the one attached directly above the frame is
Vibration is transmitted as it is because there is no damping mechanism. Noise
New In addition, there is a problem that the bolted portion is damaged. Diesel engine for centrifugal clutch
And the frame to attach the engine to the power transmission mechanism
Can be directly connected. Moves independently of belt and pulley
Power can be transmitted. Single-rail carrier other than the inventor
Is power from the clutch to the reduction mechanism by the belt pulley
It has a mechanism to transmit. With such a structure
The engine cannot be connected directly to the side of the frame. Belts and pulleys
Protrudes to the side and the engine comes directly above the frame
It is. The engine cannot be directly connected to the side of the frame
And multiple engine and frame joints
The accuracy of is worse. Vibration if there are too many joints
Since there are many modes, noise generation is also large. Heavy
Can be absorbed from directly below, so vibration cannot be absorbed and longitudinal vibration
No. And I have to change it when the belt wears out
No. It is difficult for amateurs. Requires expert visits
It is inconvenient. In addition, the belt slips and the efficiency is poor.
No. The present invention directly connects the centrifugal clutch and the reducer in the frame
There is no problem such as a decrease in efficiency due to slippage.
No. Maintenance is easy because there is no belt wear.
