Description

[Detailed Description of the Invention] Jin's invention relates to a guide device for a track vehicle that completely steers the tire by utilizing the restoring torque generated in the tire itself, thereby reducing tire wear and reducing running resistance. This invention relates to a guide device.

When a track vehicle runs on a track, it is desirable to prevent the running tire from producing a 9-angle of lateral slip as much as possible in order to extend the life of the running tire.Furthermore, a guide device that does not require a forward/backward switching device as in the past is available. Easy and desirable.

The guide system rJ/IL for a track vehicle according to the present invention solves these problems at the same time.

Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

Figure @1 is a plan view showing general mechanical characteristics of tires. First, when a lateral force Fs acts on the tire 1 while driving,
A corresponding cornering force Fc acts perpendicularly to the direction of travel. However, this cornering force Fc
In order for this to occur, it is necessary to take the angle between the traveling direction of the tire 1 and the direction of the tire 1, that is, the angle βt to be simulated.The relationship between the cornering force Fc and the lateral angle β is This varies depending on the tire size, load, tire internal pressure, etc., but under certain conditions it has characteristics unique to the tire. Furthermore, since the point of application of the cornering force Fc is far from the tire center 0 (this distance U is called the pneumatic trail), the tire center 6
A restoring torque Tg (self-lining torque) is generated in the rotation.

The guiding device of the present invention is an application of the above-mentioned principle, in which the running tire 1 is directly steered transiently by the steering mechanism through transmission from the guide wheels, and then the difference between the direction of the running tire 1 and the traveling direction is When the lateral bevel angle β occurs, an external lateral force acts on the guide wheel according to the above-mentioned principle, and the running tire l
The restoring torque Ts generated in , acts on the kingpin rotation, and the lateral slip angle β approaches O<oL7t, so that the running tire l has a bevel angle that simulates except for transient phenomena! It is possible to drive in a state close to O.

FIG. 2 is a schematic plan view showing a guide device according to an embodiment of the present invention. Similar guide devices are arranged symmetrically at the front and rear of the track vehicle. Only the guide device will be explained, and the same reference numerals will be given to the same members for those disposed at the rear, and the explanation thereof will be omitted. @2 In Figure 1, 1 is a running tire, and this running tire 1 is attached to an axle 20.
The axle 2, which is rotatably mounted on both ends via king pins 3, has a pair of left and right arms 4.5 which are swingable in a direction substantially perpendicular to the axial direction and in the horizontal direction, and have joints 4 that rotate substantially parallel to each other. Attached by s5&. Both ends ViA of each of these arms 4.degree. 5 project in the longitudinal direction of the running tire 1, and these projecting end portions have a connecting rod 6.7 and a rotating joint 6a, respectively.

6b, 7m, 7bK are machined and connected with pins. These connecting rods 6.7 each protrude to the side of the running tire 1, and guide wheels 8.8, 8 are attached to the protruding ends of these connecting rods 6.7.

The track vehicle is branched by moving a branch wheel disposed below the guide wheel 8 along a branch rail opening erected on the running road surface 9 at the branch point. In addition, in the 08RZ diagram, the branch wheel 12 is omitted in the other diagrams, and each king pin 3 has a tie rod 14 and a knuckle arm 1 that controls the steering of the railcar.

Therefore, the other end of the rod 17 is connected to the arm 4 via the U-shaped bracket 18Q as shown in Figures 5 and 6.
The arms 21 and 21' of the bracket 18 are pivoted into one end of the pin fitting that completely passes through the elongated hole 19 drilled in the arm 4, so that the rod 171) can slide in the axial direction through the bracket 18t. It is connected to the arm 4 so as to be rotatable about the bottle 20. A slight gap is provided between the arm portion 21° 21' and the arm 4 to accommodate the vertical displacement angle of the rod 17.
A spring n is installed between the and bottle 20, but this spring in the sliding part is not essential and may be omitted.In other words, this spring 22ri has a buffering function. It is.

Also, as shown in Figure @7, instead of the rod 17, a piston-shaped rod 171a is combined with a cylindrical rod 171b that surrounds it, and a spring 171 is inserted between them.
It is also possible to make the axial sliding of the rod 171 smoother by using the telescopic rod 171 with a width of C. 〇@1 of the guide device according to this invention
Since the embodiment has the above-described configuration, as shown in FIG. 8, when passing through a curved road and transitioning from straight running to circular turning, the power is first transmitted from the guide shafts 8, 8, 8.8. The force is transmitted to the pin via the connecting rod 6.7 and the arm 4.
6. Connect the running tire to the king pin 3.3 times through the tie rod 14'. li steer. Furthermore, when the vehicle enters a steady circular turn, the bevel angle β, which is automatically lateraled by the self-lining torque of the running tires 1.1, approaches zero. At this time, the bottle 20 is attached to the diagonal arm 4 for sliding movement in the axial direction of the elongated hole 19.
is not restricted.

Further, as shown in FIG. 9, the vehicle A is suspended on the axle 2 at right angles to the longitudinal direction, and the guide shaft 8 has guide rails 10 and 11 K.

Since the guide device according to the present invention has the above-described configuration, when traveling on the track, the running tire 1 can be moved along a straight line or a curved line due to the difference in elastic displacement, the difference in wear, etc. of the guide wheels 8.
As shown in Fig. 181, even if there is a difference between the direction of the tire and the direction of travel, the bevel angle β automatically changes to O due to the self-lining torque of the tire due to the action of the long hole 19. The life span of the running tire 1 can be extended by completely eliminating the 0, that is, the useless lateral angle β that is steered toward the tire.

tx The guiding device according to the present invention uses a direct steering method using the transmission force from the guide wheels 8 during transient periods, and can be used in steady straight lines or turning IP! At I, the self-steering system uses the tire's self-lining torque to ensure smooth driving. In turn, since no unreasonable lateral force is applied to the guide ring 8, the service life can be extended and downsizing is also possible.

As shown in Fig. 9, the guide device according to this invention has excellent advantages such as being able to freely move the vehicle forward or backward on straight lines or curves without the need for a special forward/backward switching device. It is effective and its utility value is worth writing.
