Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a guideway bus that can run using existing streetcar rails as guide rails.

(Prior Art) To explain a conventional guideway bus with reference to FIGS. 7 and 8, a front axle 02 is attached to a vehicle body 01 for vertical movement, and a king pin 03 is connected to the front axle 02. The wheel 04 is pivotally supported, and the knuckle arm 0 is integrated with the wheel 04.
Both ends of a tie rod 07 are pivotally supported by 5 and 06, and the rod end of a damper 08 attached to the vehicle body 01 is pivotally attached to the rear end of the knuckle arm 05. One end of a connecting rod is pivotally supported on the front end of the manknuckle arm 06, and the other end of the connecting rod 09 is pivotally attached to the middle part of a support link 010 that is pivotally supported on the front arm of the axle 02. There is. Further, a support link 011 is pivotally supported on the other front arm of the axle 02, a guide cross beam 012 is pivotally supported on the front ends of the support links 010, 011, and guide wheels 013, 013 is pivotally supported. Also, guide crossbeam 01
2, the end of the lot 9 of the restoration device R014 attached to the vehicle body 01 is pivotally supported. When the guideway bus runs, when the guide wheels 013 come into contact with the guide wall 016 of the track 015, the support link 010 is rotated left and right via the guide cross beam 012t. When the support link 010 rotates,
The knuckle arm 06 rotates via the connecting rod 09, and the axle 04 is steered in the traveling direction of the guideway bus. The restoring device 014 always biases the guide cross beam 012 so as to restore it to the straight direction. Further, since the guide wheel 012 has a gap in the guide wall 016, it receives an impact every time the wheel 04 is steered.

The damper 08 buffers this impact. The wheels 04 and the entire deflection device also dampen the vibrations caused by the impact.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has the following problems: (1) It requires dedicated guide rails 015 on both sides of the track, and in the wheel steering device equipped with it, the width of the guide wheels 013 is large, and the related Therefore, the width of the guide wall 0160 has to be widened.

(2) Since the guide rail 015 is installed above the wheel running surface of the bus, an extreme level difference occurs, making it impossible for normal mixed traffic movement of automobiles.

(3) The guide wheels 013 are guided by guide rails 015 to move left and right, and steer the wheels 04 via steering devices (05 to 012), and the vehicle itself requires a special structure, and is a special vehicle. Strengthen the element.

(4) As described in +1.1 to (3) above, the vehicle guide rails also require a special structure, making it impossible for mixed traffic such as other regular buses and cars to operate, and therefore, the equipment cost will only increase. First, its versatility in operation is severely limited.

[Means for solving problems]

The train runs on streetcar rails as a guide rail.

In order to make such traveling possible, guide wheels that can roll using guide rails as a guide and a steering device that steers the bus wheels by the left and right movement of the guide wheels corresponding to the guide rails are provided. .

In addition, the steering device R is raised and retracted through means such as a cylinder to release the engagement with the guide rail, so that the bus can be driven like a normal bus by operating the steering handle.

[Effect]

By using the above means, the bus can run using the guide rails as a guide, and by disengaging from the rails, it can also be operated as a general bus.

Therefore, it is possible to travel in traffic mixed with other vehicles.

〔Example〕

In Figures 1 to 6, l is a guideway bus, 2
are rails for streetcars, and serve as guide rails 3 for guide wheels 5. A pair of guide wheels 5 have a width corresponding to the guide rail 3 and are pivotally supported on both outer ends of a shaft 6, and a guide arm 7 protruding from the center of the shaft 6 is connected to a lever 9 via a pin 8. Ru. Further, the lever 9 is connected via a pin 10 to a bracket 12 that projects from a vehicle side frame 11. Therefore, the pair of guide wheels 5 can swing up and down via the pin 8t, and can also swing left and right via the pin 10t.

A rod 1 is connected to the end of the arm 13 of the lever 9 via a pin 14.
5 is attached, and the other end of the rod 5 is connected to a lever 17 via a pin 16. A rod 19 is attached to the other end of the lever 17 via a pin 18 like a candle. The other end of the rod 19 is attached to a pitman arm 21 that can swing relative to the steering gear box part.
connected via. A locking cylinder B, which will be described later, is incorporated into a part of the rod 19, and the rod 1 is released and operated via means such as a solenoid valve (not shown).
9 can be intermittent in its axial movement.

An intermediate portion of the lever 17 is connected to a bracket 25 fixed to the vehicle frame 11 via a shaft 24.

Now, the aforementioned pitman arm 21 swings in conjunction with the operation (rotation) of the steering wheel provided on the vehicle, and the swinging is caused by the relay rod n.
The signal is transmitted to the knuckle arm 30 via the idler arm path and the relay rod connection, and the wheels 31t of the bus 1 supported on the axle of the knuckle arm can be steered left and right. Tie rod 3 is used to attach the knuckle arms on both the left and right sides.
2, both single wheels 31, 31
can be operated in conjunction with each other.

With the above structure, if the guide wheel 5 is steered left and right with the lock cylinder 23 in operation, the shaft 6
, the guide arm 7, the lever 9, the rod 15, the lever 17, the rod 19, the cylinder n, the pitman arm 21, and the knuckle arm 30t via a known steering means.
- The vehicle side wheels 31 can be steered in the direction corresponding to the guide wheels 5 by the same angle. If the lock cylinder 23 is released to disconnect the rod 19, the guide wheels 5 and the vehicle wheels 31 can be steered independently.

Next, a mechanism for raising and storing the guide wheel 5 will be explained.

As shown in FIG. 4, the guide wheel 5 is connected to a lever 9 via a shaft 6, a guide arm 7, and a pin 8, and the lever 9 is connected to a pin 1 on a bracket 12 protruding from a frame 11 on the vehicle side.
Concatenated via 0. A cylinder holder is attached to the tip of the platen 33 fixed to a part of the guide arm 7 through a plastic plate, and the rear end of the cylinder allows the cylinder to swing up and down and left and right. It is supported for movement by a bracket 36. therefore,
By operating the cylinder 35 through means such as a solenoid valve (not shown), the guide arm 7 can be raised and lowered, and the guide wheel 5 pivoted on the shaft 6 at the tip of the guide arm 7 can be retracted.
Installation settings can be made. The dashed line in FIG. 4 shows the guide wheel 5 in a retracted state.

FIG. 5 shows an example of a locking cylinder provided in a part of the steering device, in which (5-a) shows the unlocked state and (5-b) shows the activated state.

The general structure consists of a cylinder tube 37, a rod 19, a pair of pistons 39, and an air inlet opening. Usually, as shown in (5-1), compressed air is blown into the piston 3.
By expanding the rod 19 in the axial direction, the rod 19 is fixed and integrated with the cylinder.

In addition, when operating the vehicle as a normal bus, (5-
As shown in a), the air is removed and the piston 39t-9 is moved inside to release the fixation between the rod 19 and the cylinder tube 37. In this way, the steering of the guide wheels 5 and the vehicle side wheels 31 can be made independent of each other, and the bus can be run as a normal bus by steering the steering wheels.

FIG. 6 is an explanatory diagram of the steering gear part of the steering device. When traveling using the guide rail 3 as a guide, the steering force is applied to the rod 19, the locking cylinder n, the pitcher/arm 21.
The signal is then transmitted to the known relay rod nail (the locking cylinder is activated). Also, without using guide rails, ordinary
When driving as a car, the steering force is determined by the steering wheel, steering gear box I, pitman
The signal is transmitted to the known relay rod n via the arm 21 (the locking cylinder is released).

〔Effect of the invention〕

(1) Since it uses streetcar rails and can run using the rails as a guide, there is no need for dedicated guide rails on both sides of the track as in the conventional system.

(Because there is no extreme difference between the 21 guide rail and the bus running road,
Ordinary motor vehicles can also freely mix and flow.

(3) Streetcars and guideway buses can run together.

(4J Since no dedicated rails are required for the guideway bus, equipment costs related to rail laying etc. can be reduced.

(5) Since it has the ability to run as a normal bus, there are fewer restrictions on travel routes, etc., and it is highly versatile in operation.

(6) Improved workability regarding storage, etc.
