Abstract

This invention relates to electric vehicles that receive power from a two-wire contact network. The purpose of the invention is to increase reliability when traveling vehicles when powered from one pair of contact wires. The current collector includes two rods 1 pivotally mounted on the vehicle 2. Each rod 2 under the holder is coaxially attached to an annular pneumatic cylinder of an individual pneumatic drive of the retraction of the rod. The pneumatic cylinders are interconnected by a lever through the half couplings and the auxiliary pneumatic cavities with the elastic tubular jacket. Next to each collector head, there is a sensor for contacting the contact wire connected to the wire-catching plates. When oncoming vehicles are powered by one common pair of contact wires, each driver turns on a microswitch for the right boom 2, as a result, compressed air is supplied to the pneumatic cylinder and the auxiliary pneumatic cavity. Through the lever of the other, the boom is retracted from the contact wire, freeing it to pass the boom of the current collector of the oncoming vehicle. 3 hp f-ly, 9 ill. & (L

This invention relates to an electric vehicle powered by a two-wire contact network.

The purpose of the invention is to improve reliability when driving when powering from one pair of contact wires.

FIG. 1 shows a vehicle with a pantograph collector, general view; in fig. 2 - diagram of the withdrawal of the rods with oncoming movement; in fig. 3 is a scheme for retraction of the rods when overtaking; in fig. 4 - current collector, side view; in fig. 5 is a section through an annular pneumatic cylinder; in fig. b - holder with a collector head and wire catching with thin plates; in fig. 7 - spool; in fig. 8 - lever with annular pneumatic cylinders in the working position; in fig. 9 - the same, with the abduction of one of the rods.

The device includes two articulated rods 2 mounted on the vehicle, on the free ends of which the holders 3 are installed with the possibility of rotation with current collector heads 4, interchangeable heads, and with contact wires 5.

On each rod 2, under the holder 3, an annular pneumatic cylinder 6 of an individual pneumatic drive of the rod is fixed coaxially with a movable part in the form of a radial blade 7. Cylinder 6 has a working cavity 8 in the form of a sector limited by the cylinder body b and the insert 9. The cavity 8 is connected through the nozzle 10 and the corresponding microswitch 11 with a source of compressed air (not shown). A stop 12 is installed on the insert 9, limiting the overhang of the blade 7 in the cavity 8, and the spring 13, which serves to return the blade 7 to its original position when the pressure is released. The blade 7 is fixed on the axis 14, freely covering the rod 2. The axis 14 through the coupling halves 15, 16 is connected with the hinged housing 17 mounted via a spherical bearing 18 on the rod 2. The hinged housing 17 on both rods 2 are connected by a lever 19 through auxiliary pneumatic cavities. For this, the ends of the lever 19 have radial turning in the form of rounded annular grooves, and in each housing 17 there is a through hole with sleeves 20, 21 along the edges and an elastic tubular jacket 22 placed therein, forming a sealed cavity 23 connected to the walls of the through hole through the hole 24 with a source of compressed air. The ends of the lever are installed in the through holes of the housings 17 inside the elastic shirts 22.

On the holder 3, on the axis 25 of the collector head 4, there is mounted a bracket 26 with a cylinder 27 of a contact wire contact sensor. The sensor contains located in

the cylinder 27 is spring-loaded spring 28 zalotnik 29 with the annular groove 30 and the head 31. The cylinder 27 through the nozzles 32, 33 is connected to a source of compressed air and the cylinder b of the adjacent rod 2.

On the head 31, a rusk 34 of anti-friction material is attached to the contact wire 5 and the pusher 35. On the cheeks 36 of the collector head 4, the arms 37 are hingedly mounted, on which the wire collecting plates 38 and the arms 39 interacting with the pushers 35 are fixed.

The current pick-up head 4 for co-rotation with the bracket 26 is associated with it by a plate 40 entering into the hole of the bracket.

To facilitate removal of the booms, the vehicle has drums 41 with a wound cable 42 associated with the booms.

The device works as follows.

When oncoming vehicles 1, powered by one common pair of contact wires, each driver turns on microswitch 1 for the right boom 2. At the same time, air enters the hermetic cavity 23 from the source of compressed air and firmly fixes the end of the lever 19 in the hinged case 17. At the same time, compressed air through the nozzle 10 is fed into the cavity 8 of the cylinder 6 and rotates the blade 7 relative to illkndra b and rod 2. Axis 14 through the coupling halves 15, 16 rotates the housing 17, and with it the fixed end of the lever 19, which first moves the other free end of the post, tokosemkuyu discharge head 4 of the trolley wire 5, releasing it for the passage of an oncoming vehicle.

When the left pickup head 4 is detached from the contact wire 5, the valve 29 moves upward under the action of the spring, and the pushers 35, interacting with the levers 39, raise the wire collecting plates 38 above the cheeks 36.

Vehicles are passing through the meeting by inertia, touching the contact wire with only one rod. After driving, the drivers turn off the microswitches 11, the pressure is released into cavity x-8, but remains in cavity 23 above the jackets 22 until the levers 19 return to a horizontal position.

After the collector head 4 is engaged with the contact wire 5, the latter presses on the cracker 34, as a result, the spool 29 moves downwards. The pushers 35 release the levers 39 and the plates 38 lower.

Similarly, the device works when overtaking vehicles, one after the other, as well as when the head 4 is accidentally jumped off the contact wire, and in the second case, the device operates automatically.
