The present invention is a horizontal control device for returning the posture horizontally by an inclined movement mechanism, such as an engine that becomes worse when tilted when the track driving car traveling on a track set on a slope or the like is steeply inclined. The present invention relates to a sensitivity desensitization structure in which a sense signal for detecting a critical tilt is appropriately disabled so that the tilt shift mechanism is not operated.

In orchards located on the slopes of mountains, orbits (large orbits) are installed on the ground from the foot of the mountain to the destination for transportation of crops, materials or personnel, or for various gardening operations. There are things that drive a traveling car. Orbits placed on such terrain are often repeated ascending and descending, and are often steep (about 45 degrees). By the way, this kind of track traveling vehicle consists of a tow truck and a lorry, and many tow trucks are equipped with the engine of an internal combustion engine as a drive source. Therefore, when the engine is inclined too much, the state may worsen.

Specifically, the engine oil in this type of engine (four cycles) is supplied with the oil provided in the oil tank to a mechanism linked with the crank rod, so that when the oil level of the oil inclines, the mechanism Will not function sufficiently and the oil supply will be incomplete and will stick. In addition, since the supply of fuel is performed by the intake air sucked in the carburetor, the position of the carburetor is located above the fuel tank, or the operation of the float in the interior becomes incomplete, causing fuel supply failure. Furthermore, when the fuel tank is filled with fuel, it leaks out of the cap portion, so that only a small amount of fuel can be put therein, causing a situation that requires multiple refueling.

Therefore, the present applicant proposes a horizontal holding structure which always corrects the attitude of the engine horizontally even if there is a slope (Japanese Patent Application No. 2000-267920). The engine is installed so that the engine can be tilted back and forth by the tilt moving mechanism, and the tilt is determined by the tilt sensor or the naked eye to operate the tilt moving mechanism to return to the horizontal position. Among these, when the tilt sensor is controlled by the tilt sensor, when the tilt sensor detects a predetermined tilt (critical angle) of the engine and issues a detection signal, the tilt tilt mechanism is operated to return the engine to a horizontal position. When the posture of the engine was within a predetermined inclination, the operation of the inclined movement mechanism was stopped.

For this reason, in the vicinity of the critical angle at which the inclination sensor emits a detection signal, the inclination movement mechanism is repeatedly started and stopped whenever the inclination sensor enters or exits the angle. As a result, the operation of the apparatus was unnecessarily increased, and the number of postures was not expected to be that much. In addition, such frequent occurrences cause contact wear of electrical parts, wear of brushes of electric motors, mechanical wear of moving parts, and waste of energy. The above is true of the engine, but this also applies to seats and cabins, and also to the vehicle itself.

According to the present invention, the tilt movement mechanism is not operated within a critical angle that does not cause an abnormality even when tilted, that is, the sensitivity of the tilt sensor is insensitive to prevent the consumption of energy and waste of energy.

In view of the above problems, the present invention can incline a particular vehicle or / and part of a tracked vehicle traveling on a track as described in claim 1 back and forth by an inclined movement mechanism, and at the same time, the vehicle or / and An inclination sensor for detecting an inclination on a part, and a horizontal control device in a tracked vehicle in which the inclination movement mechanism is operated by the output of the inclination sensor to return the vehicle or / and the part horizontally. It is to provide a sensitivity desensitization structure of the horizontal control device in a tracked vehicle, characterized in that the detection signal is adjusted so as not to operate the inclined movement mechanism in a predetermined range of inclinations.

In the present invention, the present invention provides three types of inclination sensors for neutral, rising, and falling, which detect a certain inclination (critical angle) according to claim 2, and the inclination sensors for rising and falling. Is inclined by a preliminary angle in the ascending and descending directions in advance, and the tilting mechanism at the rising slope operates in an AND state of the detection signals of the neutral and rising tilt sensors, and the tilting mechanism at the falling slope is neutral. Means for operating in an end state of the detection signal of the dragon and the descending tilt sensor, and instead of the neutral tilt sensor having a critical angle for generating a detection signal as described in claim 3 for the rising and falling tilt sensor, The track driving vehicle described in claim 4, which is a track driving vehicle in which a tow truck pulls a lorry and runs on the track, and is capable of tilting forward and backward. An engine provided on the driving force, it is a tilting mechanism provides a means to the engine by the expansion and contraction cylinder tilted forward or backward.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view of a track traveling vehicle according to the present invention, in which the track 1 is supported by a support 2 and provided at a predetermined height. The track | orbit 1 of this example is a mono | orbital track | orbit, and is arrange | positioned so that it may have a linear part and a curved part to a destination according to the inclination of the ground. On the track 1, a traveling vehicle 3 is placed and travels along the track 1. The traveling vehicle 3 of the present example is divided into a tow truck 4 and a truck 5, and loads a load on the truck 5, and tow the truck 4. For this purpose, the tow truck 4 is mounted on the frame 6, the engine 7, the mission 8 and various operating mechanisms 9, etc., the truck 5 is a frame 10 that can load the load (10) Is connected to the tow truck 4 with the tow bar 11.

Both the tow truck 4 and the truck 5 are provided so as not to fall about the single track 1. Fig. 2 is a cross-sectional view of the main part around the wheel of the traveling vehicle 3 showing this, and the track 1 has a rectangular cross section, and a rack 12 having a width smaller than the width thereof is provided on the rear side thereof. . The support wheel 13 and the drive wheel 14 which are in close contact with the track 1 from up and down are provided in the frame 6 of the tow truck 4. Among them, the support wheel 13 is composed of a body portion 13a placed on the upper surface of the track 1 and a flange 13b extending to the side of the track 1, and the drive wheel 14 is a rack 12 And a flange 14c extending to the side of the track 1, similarly to the pinion 14a engaging with the body 14 and the body portion 14b contacting the lower surfaces of both outer tracks 1 of the rack 12, By these, the track | orbit 1 is contacted from top to bottom, and derailment etc. are prevented.

The frame 10 of the van 5 is provided with an upper wheel 15 and a lower wheel 16 having the same structure as described above, and derailment and the like are prevented. In this example, it is shown that the van 5 does not require self-driving ability, and the lower wheel 16 is not provided with a pinion. By the way, although the above is the mono | orbital type | formula which aimed at weight support and running by the single track | orbit 1, the double track type | formula which installs a weight support rail on both sides of the track | orbit 1 may be sufficient.

As described above, when the driving wheels 14 of the tow truck 4 are driven by the power of the engine 7, the traveling car 3 composed of the tow truck 4 and the lorry 5 travels along the track 1. However, since the inclination of the front and rear is generally formed in the track | orbit 1, if it is so, it is as mentioned above that the attitude | position of the engine 7 etc. changes and various abnormality arises. Therefore, even if the track 1 is inclined, the engine 7 can be tilted back and forth so that the engine 7 can be kept horizontal, and this can be operated by the tilt shift mechanism 24.

3 is a cross-sectional view of the main part of the tow truck 4 showing the inclined movement mechanism 17, and FIG. 4 is a longitudinal cross-sectional view. First, a horizontal support shaft 17 extending from side to side on the frame 6 is bracketed ( 18), the support shaft 17 supports the engine 7. Specifically, the boss 19 is rotatably fitted to the support shaft 17, and the arm 20 is extended upward from the boss 19 to support the base 21 of the engine 7. The lever 22 protrudes from the lower side of the boss 19, and the expansion and contraction cylinder 23 (in this example, an electric cylinder) fixed to the frame 6 is connected to the lever 22. Accordingly, when the expansion and contraction of the expansion cylinder 23, the engine 7 can be tilted back and forth, it is possible to control the posture. The expansion cylinder 23 at this time needs to be locked at that position so that the expansion amount does not change even when the external force is applied to the engine 7.

By the way, typically, the power of the engine 7 is transmitted by the belt 26 to the mission 8. That is, the centrifugal crack of the engine 7 is used as the output shaft 27, and the power is transmitted by the belt 26 to the pulley 30 attached to the input shaft 29 of the mission 8 from the pulley 28 provided thereon. With the above-described configuration, the length of the belt 26 is changed by the inclined movement of the engine 7 back and forth, and the state becomes worse. Thus, in this example, the idle pulley 31 is attached to the above-described support shaft 17, and the idle pulley 31 is coped with as the relay point of the belt 26. Specifically, the upstream belt 26A, which winds the belt 26 between the output pulley 28 and the idle pulley 31 of the engine 7, and the input pulley of the idle pulley 31 and the mission 8. It is divided by the downstream belt 26B wound around 30. In addition, as the inclined movement mechanism 24, the output shaft 27 itself can be used as the support shaft 17.

In the present invention, the above-described tilt movement mechanism 24 is operated by the tilt sensor 25 attached to the engine 7 or the like. When the tilt sensor 25 of this example is inclined at a certain angle (this is called a critical angle), the contact is closed to automatically generate an electric signal, and when it is within the critical angle, the transmission of the signal is stopped (manufactured by Omuron Co., Ltd.). D5R-13), and this detection signal are read by a control device (not shown), and the expansion and contraction cylinder 23 is stretched and contracted in a predetermined direction and amount so that the posture of the engine 7 is returned horizontally. Specifically, as the inclination sensor 25, three identical sensors which emit a detection signal at a critical angle of ± 13 ° are prepared, one is made the neutral inclination sensor 25A, and the other is the inclination sensor 25B for the rising. ) And descending inclination sensor (25C). FIG. 5 is an explanatory view showing the attachment state of these inclination sensors 25. The neutral inclination sensors 25A are horizontally attached, but the inclination sensors 25B and 25C for ascending and descending are 7 ° in advance (preliminary for this). Angled up or down).

Next, the detection relationship between the inclination by the inclination sensors 25A to 25C and the driving relationship of the inclination movement mechanism 24 will be described. FIG. 6 shows the operation and the inclination movement mechanism 24 of the inclination sensors 25A to 25C. It is an explanatory view showing the movement of the expansion and contraction cylinder 23, basically the expansion cylinder 23 is a detection signal emitted by the neutral inclination sensor (25A) detects the critical angle, and the rising or falling inclination sensor (25B) , 25C) detect the critical angle and operate when the sensing signal is in the AND state. That is, if the track 1 is inclined 6 ° at the time of the rising slope, the rising inclination sensor 25B becomes 13 ° because the preliminary angle is 7 °, and detects this at a critical angle and emits a detection signal. However, since the neutral tilt sensor 25A is still 6 °, it is not detected at the critical angle, so that the detection signal does not emit. Therefore, at this point in time, the expansion and contraction cylinder 23 has not yet operated (because the detection signals of the two inclination sensors 25A and 25B do not become in an end state), and the attitude of the engine 7 is not corrected.

When the inclination of the track 1 further increases to 13 °, the neutral inclination sensor 25A detects at a critical angle and emits a detection signal, and the detection signal of the rising inclination sensor 25B is in an AND state. Becomes In this state, the expansion and contraction cylinder 23 is shortened, and the posture of the engine 7 is returned horizontally. In addition, once the neutral inclination sensor 25A issues a detection signal, the state is self-maintained and continues until the rising or falling inclination sensors 25B and 25C do not detect the critical angle. It is. That is, the rising inclination sensor 25B emits a start signal of the expansion and contraction cylinder 23, and the neutral inclination sensor 25A emits an end signal. Therefore, the calibration of the engine 7 to the horizontal posture continues during this state, so that when the posture of the engine 7 becomes less than 6 °, the expansion and contraction cylinder 23 stops working. Since the stoppage of the expansion and contraction cylinder 23 is performed even when the inclination of the track 1 is actually less than 6 °, the stopping of the posture correction of the engine 7 eventually ends when the posture is corrected so that the posture is corrected or less than 6 °. When the slope is less than 6 °.

The above-described matters are the same even when the track 1 is inclined downward, and when the downward inclination of the track 1 reaches 13 °, the expansion and contraction cylinder 23 is operated, and the attitude of the engine 7 is horizontal. When the posture of the engine 7 is corrected to be less than 6 ° or the inclination of the track 1 is less than 6 °, the operation of the expansion and contraction cylinder 23 is stopped, and the engine 7 is fixed in that attitude. In the above, if the attitude | position of the engine 7 or the inclination of the track | orbit 1 is inclination of less than +/- 6 degrees, the inclination shift mechanism 24 will not react, and it will not make useless operation in the meantime, and it will be insensitive to this. It is called an angry structure. By the way, even if it did in this way, the inclination posture within about ± 6 degrees does not have any problem in the engine 7, either.

7 to 10 are circuit diagrams showing this state. When the rising inclination sensor 25B senses a critical angle, the contact is closed to make a current flow in the coil U1 of the relay U1 (Fig. 7). Close the open contact u1. Subsequently, when the neutral inclination sensor 25A detects the critical angle, the contact is closed, and current flows in the coil H1 of the relay H1 (FIG. 9), and the open contact h1 is closed. In this state, a current flows in the coil U2 of the relay U2 which controls the driving of a motor (not shown) which is the driving source of the expansion and contraction cylinder 23, and the open contact u2 is closed to drive the motor. By operating the expansion and contraction cylinder 23, the posture of the engine 7 becomes horizontal. At this time, the operation of the neutral inclination sensor 25A is self-holding at the open contact u2 of the relay U2, and the rising inclination sensor 25B stops operating or the falling inclination sensor 25C operates. Continue until (FIG. 10).

The same applies to the descending inclination sensor 25C. When a critical angle is detected, a current is flowed through the coil D1 of the relay D1 by closing its contact (Fig. 8), and closing the open contact d1. When the neutral inclination sensor 25A senses a critical angle at that time, the contact is closed and a current flows in the coil H1 of the relay H1 (Fig. 9), and the open contact h1 is closed. In this state, a current flows through the coil D2 of the relay D2 that controls the driving of the motor as the driving source of the expansion and contraction cylinder 23, the open contact d2 is closed to drive the motor, and the expansion and contraction cylinder 23 ), The attitude of the engine 7 is horizontal. At this time, the operation of the neutral inclination sensor 25A is self-holding at the open contact d2 of the relay D2, and the descending inclination sensor 25C stops operation or the rising inclination sensor 25B operates. Continue until (FIG. 10).

The above is the basic form of this invention, and this invention is not limited to this. For example, the critical angle is not limited to ± 13 °, and the horizontal control of the posture is not limited to the engine, but may be a seat or the like and, in some cases, the whole vehicle. In addition, the actuator of the inclined movement mechanism is not limited to the electric cylinder, but may be a hydraulic cylinder or the like. Furthermore, although the preliminary angles of the inclination sensor were set to the same angle for both the rising and falling, they may be different angles. Similarly, in the inclination sensors for the rising, falling, and neutral, the sensing threshold angles may be different. Specifically, the rising and falling inclination sensors may have a smaller angle detected as a critical angle than the neutral inclination sensor, and accordingly, a preliminary angle may not be required.

According to the means of claim 1, when the vehicle or the part is inclined below the critical angle, the tilt moving mechanism for attitude control does not operate. That is, since the sensitivity is reduced, it is possible to prevent the device from reacting to unnecessary consumption or wasting energy. Moreover, according to the means of claim 2 or 3, a simple device configuration is sufficient, and according to the means of claim 4, the engine can be controlled in a simple structure.
