SU48523A1 - Adaptation to railcars in the like, serving to increase the shunt effect when passing them along rail circuits - Google Patents

Description

Practice has shown that motorized rail cars and even autocarts, due to insufficient weight, when passing through the autoblocked sections do not provide the shunt effect necessary for operating the track relay, which causes the roads to be sent to railways. This method takes a lot of useful time and at the same time does not ensure the safety of railcar traffic. The adaptation to the trolley according to the invention is intended to give the opportunity to send to the autoblocked sections of the railcar and the locomotive on a par with locomotives, without resorting to additional communication methods.

In FIG. 1 and 2 depict in two projections one half of the proposed adaptation.

On each trolley, two completely identical devices are installed, each of which consists of two main parts: the outer cup / and the inner movable part 2 with a tapered roller 3. The outer glasses 7 with their upper part are attached to the rail frame between the slopes by means of the transverse bar 4.

The inner movable part together with the roller 3 under the action of the spring 5 tends to go down and is supported by the roller on the rail.

To limit the downward movement of the inside of the bowl, screw 6 serves to limit the downward movement of the roller by 2 cm. The upward roller, together with its movable part, can only rise 3 cm. When moving the trolley, the roller with its beveled part rolls along the inner side of the rail; Since the area of contact between the roller and the rail is insignificant, the pressure per unit is continuous, this is very large, which results in a good shunt contact. In addition, the contact duration is determined by the fact that the inner side rail is always clean, since in this place it is erased with the ridge of the carriage ramps, as well as by the fact that the roller gets considerable friction both longitudinal and transverse.

An increase in the shunt effect is furthermore ensured by the fact that both devices are mounted on the same metal bar 4 and the rollers are electrically connected between themselves by means of rubbing end contacts 7.

The subject matter of the invention.

Adaptation to rail cars, etc., which is used to increase shunt

effect when passing them along the rail chains, characterized in that it is made in the form of two conical rollers, pressed under the action of

springs to the inner side of the rails and electrically interconnected by means of rubbing end contacts.
