Abstract

PROBLEM TO BE SOLVED: To provide a pole device of a master controller having structure which can adjust a change of an operation force by adjusting a spring free length of a star wheel of the pole device arranged at the right end of a main camshaft with respect to a change of a main handle operation force of the master controller.SOLUTION: A cam and a gear are arranged at the camshaft 12, bearing tables are arranged at both ends, the pole device 9 is arranged at the right end, a spring fixing table 7 of the pole device 9 is made to be movable, and the spring length can be adjusted by making the spring fixing table 7 movable in the fore-and-aft direction by an adjusting handle 1. Since the operation force can be adjusted by only the handle operation, the operation force can be adjusted in a short time. Furthermore, a moving mechanism of a spring attachment table of the pole device is made to be continuously movable in position using lead screws, and the spring length becomes continuously adjustable.

Description

  The present invention relates to a main controller for a railway vehicle equipped with a mechanism for adjusting a main handle operating force.

  4 and 5, the conventional pole device is fixed to the base 5 side, while the star wheel 11 is fixed to the cam shaft 12 side together with the cam 13, the gear 14 and the like. . The roller 10 of the pole device 9 always pushes the concave and convex portion 11a of the star wheel by the coil spring 8, and when the cam shaft 12 rotates, the roller 10 falls into the concave portion, generating a response and simultaneously determining the notch position. ing. Among them, the element that determines the operating force is the force generated by the coil spring 8 that is generated according to the shape of the uneven portion of the star wheel 11.

  In the conventional polling device, when a change in the response of the main handle is requested by a customer or the like, the notch is obtained by replacing the star wheel 11 by disassembling the camshaft or replacing the spring of the pole device 9. The response at the time of switching was adjusted. However, the replacement of the star wheel requires the camshaft 12 to be removed from the bearing base 15, and the replacement of the spring also takes time and effort, such as opening the master controller surface cover 16, and requires a replacement time. did. A main controller for a railway vehicle having an operation force adjusting mechanism is described. (For example, Patent Document 1)

  The problem to be solved is that it is difficult to change the operating force of the master controller main handle after the assembly is completed.

  In order to solve the above-described problem, according to claim 1, a camshaft connected to the main handle and rotated by the operation of the main handle, and the main handle provided at the end of the camshaft A star wheel that rotates integrally with the rotation of the camshaft that gives a response to the switching notch position and has an unevenness on the outer peripheral portion, and a roller that rotates freely is pressed against the unevenness of the starwheel via a spring A main controller for a railway vehicle having a pole device fixed to a base of the controller, characterized by comprising spring mounting position movable means for the pole device.

  According to a second aspect of the present invention, in the first aspect, the movable means includes a four-joint link and a feed screw having the same length. For example, the mechanism of a pantab rough jack.

  According to a third aspect, in the first and second aspects, a handle for rotating the feed screw is provided through the upper surface of the master controller.

  According to a fourth aspect of the present invention, in the first and second aspects, the pair of fulcrum points of the four-bar link opposite to each other are arranged on a freely-rotating nut-shaped member on the feed screw, respectively. One of the other pair of fulcrums facing each other is arranged on the spring mounting member of the pole device.

  According to Claim 5, in Claim 3, the uppermost surface of the adjustment handle for rotating the feed screw is lower than the surface of the master controller.

  That is, the present invention has the main feature that the operating force of the master controller can be adjusted only by operating the adjustment handle provided on the console, without using a tool.

  The master controller of the present invention has the advantage that the operating force can be adjusted in a short time because the operating force can be adjusted only by operating the adjusting handle. In addition, the moving mechanism of the spring mounting base of the pole device portion is a continuous position movement using a feed screw, and the spring length can be adjusted steplessly.

It is explanatory drawing which showed the implementation method of the master controller. Example 1 It is explanatory drawing which shows one Example using the thing of FIG. It is explanatory drawing which showed the operation example of the mechanism using the thing of FIG. It is explanatory drawing which shows the positional relationship of the conventional poll apparatus and a star wheel. It is explanatory drawing which showed the apparatus arrangement | positioning in a master controller.

  We realized that the purpose of changing the operating force of the master controller can be performed only by operating the handle for adjusting the operating force on the console, which is the surface cover of the master controller, without the need for complicated adjustment work.

The spring force acting on the master controller operating force is based on Hooke's law.
F = kX (F: spring force k: spring constant X: amount of spring deformation)
In order to change the spring force (F), it is necessary to change the spring constant (k) or the deformation amount (X) of the spring. As a method of changing the spring constant (k), there is a replacement of the spring itself, but as described above, it takes time and requires a replacement time. Therefore, in the present invention, pay attention to the amount of deformation (X) of the spring. In addition, by making the spring end fixed portion movable, the spring deformation amount (X) can be arbitrarily adjusted.
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of the main part showing one embodiment of the present invention, FIG. 2 is an explanatory view showing details of the mechanism using the one of FIG. 1, and FIG. 3 shows an operation example of the mechanism using the one of FIG. FIG.

FIG. 2 is a detailed view of the embodiment of the apparatus of the present invention, and shows a spring fixing base moving mechanism by turning the adjustment handle 1.
By rotating the adjustment handle 1, the spring fixing base 7 moves back and forth, and the free length when the coil spring 8 is attached can be changed.

  As shown in FIGS. 2 and 3, the spring mounting base moving mechanism uses a pantograph type screw type jack mechanism, which enables fine adjustment of the spring mounting position of the screw rod (feed screw) 4. Further, by using this structure, the phenomenon that the spring fixing base 7 moves due to the reaction force of the spring mounting portion when the main handle is operated is prevented.
