Abstract

The invention relates to a control switch of a control controller for electric dependent traction. It provides a frame for mounting a control switch of a control controller. The frame is composed of end longitudinal members, four connecting cross members and one or two middle longitudinal members. The end longitudinal members are formed by a carrier and upper and lower outer machined strips. The middle sub-members are formed by a carrier and upper and lower middle machined strips. All machined strips have internal centering surfaces on their adjacent sides. The invention can be used in control controllers, in particular for electric dependent traction.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering controller control switch for electrical traction.

Resolves a ground for attaching the control controller steering switch.

The skeleton is composed of outer side members, four connecting cross members and one or two middle side members. The side rails are formed by the carrier and the upper and lower outer strips. The central partboards consist of the carrier and the upper and lower middle treated strips. All machined strips have inner centering surfaces on adjacent sides.

The invention can be used in controllers, in particular for electrical dependent traction.

The invention relates to electrical apparatus frameworks, in particular to rail vehicle control apparatus, for example controllers, in which a low apparatus height and a small built-up space are required.

Devices are known whose skeletons form their outermost dimensions or the skeletons are the base plates on which the devices are built on one side. The carcasses are usually welded from rolled profiles and have welded-on bearings or bearing surfaces to accommodate other components. The carcasses produced in this way are difficult to process, are materially heavy, and assembly of the components into the carcass is difficult. Their further drawback is that they excessively increase the size of the device.

These drawbacks are overcome by the object of the invention that the longitudinal side members formed by the carrier, the upper outer working belt and the lower outer working belt are joined by at least two connecting crossbars connected to each other by a central longitudinal formed by the carrier and the upper and lower middle working belt. The upper and lower outer machined strips and the upper and lower middle machined strips are provided with inner centering surfaces in the caster interior.

The interconnection of the connecting crossbars can be made by two central longitudinal members. The complete carcass of the device may be formed by two carcasses between which spacers are inserted.

1 to 6 of the drawings show a practical embodiment of the invention. Fig. 1 is a plan view of the frame of the apparatus; Fig. 2 is a cross-section of a frame with one central longitudinal member. Fig. 3 is a cross-section of a carcass with two central longitudinal members. Fig. 4 shows a complete carcass consisting of two carcasses and spacers. Fig. 5 shows the practical use of the carcass according to the invention in a control unit for controlling two functions. Fig. 6 is a practical plan view.

In Fig. 1 there is a skeleton with outer longitudinal members 1 with four connecting crossbars 2 and one central longitudinal member 3.

FIG. 2 is a cross-sectional view of a carcass with one central longitudinal member formed by the carrier 4, the upper middle processing belt 8 and the lower middle processing belt 3. The outer longitudinal members are formed by the carrier 4, the upper outer processing belt 5 and the lower outer processing belt 6.

All machined strips 5, 6, 8, 3 have inner centering surfaces 7 on adjacent sides.

Fig. 3 is a carcass with two central longitudinal members having outer longitudinal members identical to those of Fig. 2. The central longitudinal members are located in the carcass with a small gap between them and are formed of a carrier 4, an upper middle treated strip 8 and a lower middle treated The inner centering surfaces 7 are only on the sides of the treated strips which face the longitudinal side members.

In Fig. 4 there are two carcasses 10 which are connected by spacers 11 which extend through the entire cross-section and can advantageously replace the cam roller bearings and possibly also the mounts for attaching the whole apparatus if they protrude outside the carcass.

In Fig. 5, on the upper side of the carcass 10, on the left and right side, there is a right and left operating device 12, 13 comprising a control lever, a position lock, a cam roller drive and possibly a locking device. The cam switches 14 are located on the underside of the chassis.

In Fig. 6, the left hand side of the carcass 10 is provided with a left-hand control device 12 for operating the I function, which controls the cam cylinder 17 located at the bottom of the carcass 10. On the right side of the carcass is a right hand control device 13 for controlling II. a function that controls the cam roller 18 located on the underside of the carcass. Cam switches 14 are disposed between the control devices 12, 13.

The flat carcasses according to the invention are structurally simple, have low material consumption. Only milling and drilling on conventional machines, without demanding jigs, is used for their machining. The possibility of mounting components from both sides of the frame allows easy and well-arranged assembly and easy maintenance in operation.

The greatest advantage, however, is in the construction of devices in the type series, where only the length and possibly the number of chassis vary according to the number of cam switches, the number of cam cylinders, the number of functions and the cam cylinder program. Thus, most components are identical, that is to say, unification of components is used to the greatest extent.
