Description

The invention relates to the field of general purpose vehicles and can be used as current collectors of trolleybuses and trams.

Known current collector of the vehicle containing the base, the contact head and the rod, made in the form of two articulated parts, the upper of which is shorter than the bottom 1,

The disadvantage of this device is the complexity of its design due to the presence of two hinged articulated parts and the large reduced mass of the current collector, resulting in increased wear of the contacting elements.

Also known is the vehicle’s current collector, which comprises an L-shaped shanta fixed to the vehicle, on the horizontal arm of which it is mounted so that it can move in the vertical direction and rotate the shanks around the vertical axis, carrying the contact head 2.

However, this device is not sufficiently reliable because of the jamming of the stroke of the rod with the head from the effect of the friction force of the insert on the trolls, which is directed perpendicularly to the movement of the rod.

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that the current collector of the vehicle, containing an L-shaped shanta fixed on the vehicle, on the horizontal arm of which is mounted with the possibility of movement in a vertical

in the direction and rotation around the vertical axis, the rod bearing the contact head is provided with an elastic element fixed at one end on the horizontal arm of the L-shaped rod and inclined in the plane of the latter by an elastic element connected by the other end to the rod.

FIG. 1 shows a current collector; in fig. 2 is a diagram of the forces applied to the hinge of the head attachment with the rod.

The device comprises a rigid L-shaped bar, the vertical arm of which is mounted in the hinge of the base 1. The end of the horizontal arm of the bar 2 is connected to the rod 3 by the hinge 4.

At the upper end of the rod 3, a contact head 6 is mounted by means of a hinge 5, preloaded by a spring 7. The hinge 5 is connected by an elastic element 8 to a horizontal arm of a rod 2.

The current collector works as follows .1

When the head of the 6 current collector slides along the contact wire, the hinge 5 is permanently affected by the friction force of the Trolley. The elastic force from the elastic element 8 is directed in such a way that the resultant force Pg., Applied to the hinge 5, is directed along the axis of the stroke of the rod 3.

The use of the proposed device will improve the reliability of its operation by providing free movement of the rod with the head by compensating for the friction forces of the troll insert, which is directed perpendicular to the stroke.
