Abstract

Contact clutch designed especially for trolleybus trolleybus, consisting of a pair clamps to clamp both ends of the splice trolleys that run upward. terminals they are interconnected by strips from below for collector contact. Outside distance the skirting is smaller than the inner size of the head but is larger than the groove width carbon collector.

Description

SUMMARY OF THE INVENTION The present invention provides a trolley coupling intended especially for a trolleybus trolley. It consists primarily of a pair of clamps for catching both ends of the connected trolley that extend upwards. The terminals are interconnected by bottom rails adapted for contact with the pantograph.

The prior art contact couplings used for the trolleybus trolley usually use terminal strips in which the trolley is inserted by means of a longitudinal recess, after which the terminal strips are tightened by screws. If it is necessary to make an insulating joint, the terminals made in this way are connected from above by an insulator. Especially in this case, when it is necessary to create a gap between the two ends of the connected trolley, there are failures of the so-called trolley couplings under the influence of arc and mechanical stress.

In another case, the overhead contact is formed as a push-on profile on the upper part of the overhead contact. From the top, screws are inserted into the profile by pulling the contact rail into the recess in the sliding profile. This coupling is not usable as insulating.

In the construction of the overhead contact line, however, various types of overhead contact couplings are known which allow the traction vehicle to pass at high speed, without interrupting contact with the pantograph, as well as damaging the structure of the overhead contact. However, these overhead couplings are not usable for trolleybus traction, since they provide for overhead rails equipped with a cross rail. Therefore, at the point of connection of both ends of the trolley, the entire width of the skid is used, which is impossible with the trolleybus shoe.

The above-mentioned drawbacks are overcome by the trolley coupling according to the invention, which is particularly intended for the trolleybus trolley. It consists of a pair of terminals to catch both ends of the connected trolley extending upwards. The terminals are interconnected by bottom rails adapted for contact with the pantograph. The outer spacing of the rails is smaller than the inner dimension of the pantograph head, but is greater than the carbon grooves of the pantograph. The strips can be connected to each other. In one case the strips are made of insulator, in another one of conductors.

The external distance of the rails less than the internal dimension of the pantograph head ensures that the pantograph is guided laterally to the contact. The outer spacing of the rails is greater than the width of the carbon groove of the pantograph, then the continuous overhanging overcoming of the so-called overhead contact coupling according to the invention. This is because when the contact clutch according to the invention is approached, the contact rail extends upwards, whereupon the carbon abuts on the rails on both sides of the groove.

For greater rigidity it is advantageous if the strips are connected to each other.

An exemplary embodiment of an overhead contact coupling according to the invention is shown in the accompanying drawings in FIG. 1 in an overall view as a connection of the two ends of the contact wire and in FIG. 2 as a connection of the contact wire to some part of the contact wire; l.

The overhead contact coupling according to the invention consists of a pair of terminals 2 for engaging both ends of the contact wire 1 which extend upwards. The clamp 22 may be adapted by a grip 21 to engage some part of the trolley not shown in the drawing. The terminals 2 are interconnected by rails 3 from below adapted to engage the header 4. For greater stability, the two rails 3 are joined together by a connector 31. The outer distance of the rails 3 is smaller than the inner dimension of the head 41 of the header 4 but greater than the width of the groove 43 In the conductive connection of the two ends of the contact wires 1, it is advisable to make the blades 3 from the conductor, but if it is an insulating connection of the two independent contact wires 1, the strips 3 are made of insulating material.

When the trolley bus collector passes through the trolley coupling according to the invention, the contact of the trolley 7 with the groove 43 is interrupted.

After the strips 3 have been rolled with carbon 42, the groove 43 is again approached on the trolley 1, since the collector 4 is guided laterally by the inner dimension of the head 41 and the control 2 is mounted in the axis of the strips 3 '.
