Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides that electrical conductors led through a train form a safety circuit loop that can be bridged by contacts, and that the car end coupler of the vehicle is provided with a force-operated coupling release device. The present invention relates to a device for monitoring separation between a plurality of connected vehicles forming a train, which can be released from the connected state by applying force.

In trains consisting of multiple cars, in accordance with regulations, if cars suddenly separate, the brakes must be applied automatically to at least the part of the train that is separated. This function is normally accomplished through compressed air brake piping that runs through the entire train or, especially in modern short distance trains, through electrical conductors (safety circuit loops) that run through the entire train.

In the case of uncoupling, ie intended train separation, automatic forced braking is not necessary, nor is it desirable as it would interfere with operation. In order to avoid such forced braking, it is necessary to distinguish between an unexpected train separation (accident) and an intended train separation (normal operating mode). When using train air brake piping that runs through the entire train, the automatic coupling device automatically closes the brake piping by means of the unlocking device of the coupler locking device when the connection is removed.

With a safety circuit loop formed by four electrical conductors, detection of train separation is possible by opening the safety circuit loop. As a result, brakes are automatically applied to the separated train parts.7L3° If the intended train separation is to be performed, for example to disconnect the train, the monitoring function must be deactivated beforehand.

However, the introduction of a safety circuit loop and the regular maintenance of its monitoring function during operation require a unique recognition of "leading (coupled) cab,""uncoupledcab," and "uncoupled rear cab." shall be. Recognition of an uncoupled cab can be made by the closed operating switch, and recognition of uncoupled rear operation can be made by the state of the automatic coupler.

In order to avoid opening the safety circuit loop at the moment of disengagement, the driver must bridge the safety circuit loop by manually operating a switch to avoid applying the brakes. However, the bridging switch is not desirable from a safety standpoint. This is because the safety circuit loop cannot perform its original function until the switch is returned to its original open/closed position.

An object of the present invention is to provide a monitoring device that prevents forced braking from being applied during intended train separation while maintaining the monitoring function.

According to the invention, this purpose is achieved by providing in each end coupler half a contact of a monitoring switch, which contact responds to actuation by a force pulse in the actuating device of the associated end coupler half and causes the connection to occur. According to the present invention, a corresponding Eliminates the need for manually operated bridging switches, which can be dangerous. This prevents, by simple means, unnecessary activation of the emergency braking in the event of uncoupling, without compromising driving safety, and thus prevents uncoupling even when electrical safety circuit loops are used. You can do it freely.

Furthermore, according to the invention, a zero-force driven coupler release device is provided in each case, which makes it possible to achieve simplification of operation during vehicle maneuvering by simple means without sacrificing driving safety. Depending on the situation, it can be operated electrically, hydraulically or by compressed air.

Next, one embodiment of the present invention will be described in detail with reference to the drawings. 〇 Figure 1 shows train cars 1 and 2 connected to each other via an automatic coupler ◇ Each car 1. 2 has a front driver's cab FSX, a rear driver's cab FS2, and car end coupler halves XI and X2 attached to the driver's cab. This automatic coupler can be uncoupled using compressed air.

As shown schematically in FIG.
A compressed air pipe 3 is provided at I and X2, and a connection release valve 3a for disconnecting the coupler is provided therein. The compressed air line 3 is led into a hole 5 formed in the joint surface of the coupler and into an operating cylinder 4 in the reservoir of a travel bottle 6.

To monitor the separation of the cars 1, 2, two electrical conductors 8, 9 are led through the entire train via the electrical contacts 7 of the coupler. When the vehicles 1, 2 are connected, the two electrical conductors 8, 9 form a safety circuit loop SF (solid line) connected to a voltage source in the vehicle 2. This safety circuit loop SF

The safety circuit loop is closed via 2. When the safety circuit loop SF is opened, the excitation of the emergency brake valve 10, which had been energized up to that point, is cut off and the compressed air brake is applied.

Each car end coupler half XI, in order to prevent the compressed air brake from operating in the event of intentional train separation by manual (yet still electrically remote controlled) actuation of the coupling release valve 3a; , X2 is a monitoring switch Fl configured as a pressure monitoring device.

At the same time, a voltage (10 poles of the vehicle power supply) is applied to the safety circuit conductor 11 by 1 or 2 to other contacts in the now separated vehicle 2, forming an independent closed safety circuit loop SF2 shown by the dashed line. .

Also in the vehicle 2 with the hitherto connected driver's cab, a closed safety circuit loop SFI, shown in dashed lines, is formed by actuation of the coupler contacts s3 and S4, as in known configurations.
