Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a handle of a main controller for a vehicle in an electric railway vehicle.

[Conventional technology]

Conventionally, in the operation of electric railway vehicles, a driver performs acceleration / deceleration operation of a vehicle by operating a steering wheel of a vehicle master controller (hereinafter referred to as a master controller). The one-handle type with one deceleration notch is the mainstream.

4 and 5 are a front view and a side view showing a handle portion of a main controller of a conventional example, 1 is a handle, 2 is a stopper interlocking with the handle, 3 is a bearing stand, 4 is a frame, and 5 is a notch. It is a cover displaying the position.

Fig. 6 is an enlarged explanatory view of the cover showing the notch position. OFF is the neutral point, B _{1 to} B ₃ are mechanical brakes, P ₁ and P ₂ are low speed operation, 1 is regenerative braking, N is the current speed maintenance. , + Indicate each notch position for acceleration.

An example of the operation from start to stop of the train will be described with reference to FIGS. 4 to 6. The neutral point is OFF (stop) → low speed operation P ₁ (start) → low speed operation P ₂
(Low speed) → Acceleration + (Acceleration) → Maintain current speed- (Constant speed) →
Regenerative brake- (electrical brake) → mechanical brake B ₂ (mechanical braking) → mechanical brake B ₃ (large mechanical brake) →
Mechanical brake B ₁ → (stop).

The main controller has a mechanism called a star wheel mechanism, which is composed of balls, springs, and receiving seats, so that each notch position does not slip and the operating force is not applied to move the notch position.

[Problems to be solved by the device]

However, the conventional method has the following drawbacks.

That is, when moving the notch position, an operating force is needed to overcome the resistance force of the star wheel mechanism,
Since the top notch is dedicated to acceleration (Fig. 6 + position), it is natural to apply a force when accelerating, but when canceling the acceleration it is natural to simply return to the current speed maintenance state, which is safe. It is also desirable from the aspect.

[Means and actions for solving the problem]

The present invention has been made in view of the above problems, and facilitates notch return operation by providing another return function only when returning from the uppermost notch position to the position one step before.

That is, a compression spring is provided that works effectively only when the handle stopper part of the main controller moves to the uppermost notch. When accelerating by using this spring pressure, an operating force is required, but the acceleration is stopped. Sometimes I relax my power,
The mechanism naturally returns to the previous notch and returns to the current speed position.

〔Example〕

An embodiment according to the present invention will be described below with reference to FIGS.

1 and 2 are a front view and a side view of the master controller showing a state in which the notch is located at the uppermost one-stage front side, and FIG. 3 is a side view showing the master controller in which the notch is at the uppermost position. In the figure, 6 is a spindle, 7 is a return spring, and the devices having the same reference numerals as in FIGS. 5 and 6 show the parts having the same functions.

As shown in FIGS. 1 to 3, a spindle 5 and a return spring 6 are provided between the bearing stand 3 and the frame 4, and only the uppermost + notch is mounted so that the return spring acts.

That is, at the notch on the uppermost one step, the return spring 7 does not act because the stopper 3 interlocking with the handle 2 is separated from the spindle 6 by the head. When the handle 1 is moved to the highest notch, the stopper 2 moves the spindle 6
And the return spring 7 is compressed. On the contrary, when lowering from the uppermost notch by one step, the operating force of the handle 1 is only loosened, and the restoring force of the return spring 7 can smoothly return to the position one step before.

[Effect of device]

As described above, according to the present invention, when returning from the uppermost notch position to the notch position one step before, a return mechanism by a spring is added, so that the handlebar is not stopped at the uppermost notch position (acceleration operation) for a long time. It is possible to provide a special device that improves the operability and safety of driving in the main controller of the driving and running method.
