Abstract

PURPOSE:To simplify the construction and to reduce the size and the weight of a master controller by providing a rotary encoder which converts the rotating position of a handle to a rotating angle, detects and outputs it. CONSTITUTION:When a driver rotates a main handle 13 by hands to perform a power drive or a brake of a vehicle, a rotary encoder 16 operates through gears 14, 15 to output a digital detection signal of a rotating angle in response to the rotating angle of the handle 13. A controller converts this signal to a notch signal and outputs a power drive or brake control command signal as the driver operates. Thus, many conventional cams and control switches can be omitted to reduce the size and the weight and to further improve the operability.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a main controller for a railway vehicle, etc., which outputs control commands for moving or braking the vehicle in response to a rotational operation of a steering wheel by a driver.

[Technical background of the invention and its problems]

Generally, the main controller in a railway vehicle is shown in Figures 7 and 8.
As shown in the figure, a main handle (lever) 3 with a detent man 2 is rotatably provided in a state protruding from a case 1 of the main body of the controller, and a gear 4 is provided on a shaft 3a of the main handle 3. A driven gear 6 that interlocks with this gear 4 via an intermediate gear 5 is provided on the camshaft 7. The camshaft 7 is long and has a large number of cams 8 attached thereto, and a control switch 9 for driving the vehicle and braking is provided in correspondence with each cam 8. .

When the driver manually rotates the main handle 3, the camshaft 7 rotates together with a large number of cams 8 in conjunction with the rotation of the main handle 3 through gears 4 and 5. , each control switch 9 is turned on according to the rotation angle of each cam 8,
When the switch is turned off, it outputs step-by-step command signals for driving the vehicle and braking.

The gear ratios of each of the gears 4, 5, and 6 are set so that the rotation angle of the main handle 3 becomes an angle that allows each cam 8 to switch the control switch 9.

By the way, these conventional master controllers usually require more than ten cams 8 and control switches 9, which not only requires a large number of parts and a complicated configuration, making assembly difficult, but also requires a large space to accommodate them. Case 1 is necessary, and the main controller inevitably becomes large, making it difficult to place the main controller in terms of space, ease of movement of the driver, and operability when laying out the driver's cab of the vehicle. was there.

Furthermore, since a large number of control switches 9 are switched by the cam 8, a large switching blade is required, making the handle operation heavy and inconsistent, making it difficult to operate the handle smoothly and accurately. Furthermore, since the control switch 9 generates harmful gas when it is turned OFF (current cutoff), there is a concern that it may have an adverse effect on surrounding equipment, and a gas vent must be provided, which is inconsistent with dust prevention, and regular maintenance and inspections are required. When performing maintenance and inspection, a large cover must be attached, removed, opened and closed, and a large space must be secured for this purpose.

[Purpose of the invention]

This invention was made in view of the above circumstances, and it has a simple structure and is easy to assemble, is significantly smaller and lighter, and can be easily placed in the driver's cab, making effective use of space and making it easier to move.・The aim is to provide an extremely superior main controller that can improve operability and simplify maintenance and inspection.

[Summary of the Invention] In order to achieve the above object, the main controller of the present invention is a rotary encoder that converts the rotational position of the steering wheel into a rotation angle in conjunction with the rotational operation of the steering wheel by the driver and outputs the detected rotation angle. This configuration is equipped with a control device that converts the signal from the rotary encoder into a notch signal and outputs it as a control command for vehicle movement or braking.It is possible to omit a large number of conventional cams and control switches, and the configuration is simple. It is possible to significantly simplify, reduce size and weight, improve operability, and solve problems such as generation of harmful gases.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, reference numeral 11 indicates the case of the main body of the controller, and this case 11 has a main handle 1 with a dead man 121, which is similar to the conventional case.
3 is attached so as to protrude so that it can be rotated. Also, inside the case 11, a gear 1 is attached to the shaft 13a of the main handle 13.
4 is attached, and a rotary encoder 16 having a driven gear 15 that directly meshes with the rotary encoder 16 is provided. Further, a star wheel 18 is attached to the end of the shaft 13a of the main handle 13 as a latch mechanism 17 for positioning various rotational positions of the main handle 13, and a rolling contact roller 19 is constantly pressed against the lower side of the star wheel 18. The main handle 13 is attached via an arm 21 biased by a spring 20 to provide an appropriate notch feel when rotating the main handle 13 and a positioning action at various rotational positions of the main handle 13. It looks like this.

The rotary encoder 16 rotates in conjunction with the rotation operation of the main handle 13, converts the rotation position of the cough main handle 13 into a rotation angle, detects it, and converts it into a digital signal. The digital signal output from the rotary encoder 16 is converted by a control device (not shown) into a control command signal for driving or braking the vehicle, that is, a notch signal, and then output. The control device may be installed inside the case 11 of the controller main body, but in order to make the controller main body even smaller 6, it is better to install it separately at an appropriate position in the vehicle. .

Therefore, in the master controller having the above-mentioned configuration. When the driver manually rotates the main handle 13 to move or brake the vehicle, the rotary encoder 16 is actuated via the gears 14 and 15, and the rotary encoder 16 operates according to the rotation angle of the main handle 13. A digital detection signal of the rotation angle is output, and this is converted into a notch signal by a control device (not shown), which is output as a power or braking control command signal according to the driver's operation.

Here, since one rotary encoder 16 can output a plurality of rotation angle signals, there is no need to provide a large number of conventional cam drive control switches, and the rotary encoder 16 itself is small.
The main controller body (case 11) can be made much smaller and lighter than the conventional one.

Further, since the driving force of the rotary encoder 16 itself is very small, the main handle 13 can be operated lightly and smoothly. For this purpose, the operating force of the main handle 13 and the notch feel of its rotational positioning can be freely matched to the driver's preference by selecting the shape of the star wheel 18 of the latch mechanism 17 and the pressing force of the rolling contact roller 19. becomes possible.

Furthermore, since the rotation detection angle of the rotary encoder 16 can be reduced, the rotation angle or stroke of the main handle 13 can be reduced, thereby improving operability and downsizing.

Furthermore, since the rotary encoder 16 is used, there is no need to worry about the generation of harmful gases that adversely affect surrounding equipment, unlike conventional control switches, and there is no need to provide gas vent holes in the case 11. The dust-proof sealed structure improves reliability, and at the same time, the structure is simple and contactless, making maintenance free or extending the maintenance cycle.

Next, another embodiment of the invention will be described.

First, in the case of Fig. 3, in addition to the configuration of the main controller that issues commands for moving and braking the vehicle, a configuration that issues commands for switching the vehicle forward and backward is provided, and the slightly thicker A case 11A is provided with parts similar to the above-mentioned embodiment, and a reversing handle 13A1 and a forward/reverse rotary encoder 16A interlocked with this shaft 13Aa via gears 14A and 15A. Even in this case, although it is a little thicker, it is much smaller and lighter than the conventional one, and the same effects as those of the above embodiment can be obtained.

In the case of FIG. 4, the rotary encoder 16 is directly connected to the shaft 13a of the main handle 13, and can be housed in a small horizontal case IIB.

In the case of FIG. 5, the shaft 13a of the main handle 13 and the rotary encoder 16 are interlocked by a bevel gear 140° 15C, and can be housed in a small case 11C that is long in the front and back direction.

In the case of FIG. 6, the same bevel gears 14D and 15D are meshed at the top and bottom, and the whole is housed in a small vertical case 11D.

As a result, the main body of the controller can be made smaller and lighter, and its external shape can be selected from various shapes such as horizontal or vertical, making it possible to effectively utilize the space in the driver's cab, making the driver's cab thinner, increasing visibility, etc., and improving portability and safety. This will help you improve your skills.

〔Effect of the invention〕

Since this invention is made as described above, it is possible to omit a large number of conventional cams and control switches, and the structure is simple and easy to assemble, and it can be significantly reduced in size and weight, making it easy to place in the driver's cab. It is an extremely superior main controller that can be used to make effective use of space and improve ease of migration, as well as improve operability, solve problems such as the generation of harmful gases, and simplify maintenance and inspection.
