UA68837A - Drive of a compressor of electric train - Google Patents

Abstract

Drive of a compressor of electric train has electric motor, this is connected to the shaft of the compressor. On the shaft a pinion is placed, this is in permanent contact with the pinion that is placed in free way on the axle of the wheel couple, it has bosses on the end surface and is supported by a spring at one end and a muff connected to the electromagnetic control unit at the other one; and at the inner side of the wheel of the wheel couple there is a mouth-piece with openings for the bosses on the pinion.

Description

Description of the invention

The invention relates to railway transport and relates to the construction of a compressor drive of a suburban electric train.

The invention is aimed at solving the existing problem of reducing electricity consumption when replenishing the air supply in receivers.

The compressor drive of an electric train, which contains an electric motor connected to the compressor shaft, is known. (Railways. General course. Edited by M.M. Uzdina. M., Transport, 1991. p.). 70 But such a compressor drive does not save electricity when replenishing air reserves in receivers.

The motor-compressor type "3-СО" and its modifications are the closest to the claimed invention.

The improvement involves the presence of a universal housing, which is installed between the electric motor and the compressor. The housing has a bearing supported on the output end of the compressor crankshaft and flanges, which are bolted to the electric motor and all modifications of the "3-СО" compressor. (US Pat. 6364635, IPC 7"

E04817/00).

The disadvantage of this design is the impossibility of using the kinetic energy of the train movement to replenish the air reserves in the receivers.

The technical problem solved by the claimed invention is the improvement of the compressor to minimize the cost of electricity when using the kinetic energy of the train movement to replenish the air reserves in the receivers.

The essence of the invention is that a gear is mounted on the compressor shaft, which is in continuous contact with the gear, which is freely mounted on the axle of the wheel pair, has protrusions on the end surface and is supported by a spring on one side, and a clutch connected to the electromagnetic the driver, - from the second, and on the inner side of the wheel of the wheel pair there is a nozzle that has holes for protrusions on the gear. "

Fig. 1 shows the electric train compressor drive - a general view, Fig. 2 shows the connection of the gear with the wheel pair.

The compressor drive of the electric train has a compressor 1, on the shaft 2 of which a gear 3 is mounted, which is in contact with a gear 4, which is freely mounted on the axle of the wheel pair 5 and through a spring 6 is fastened to a nozzle with holes 7.

The gears are controlled by the electromagnetic controller 8, the axis 9 of which is connected to the lever 10, which is connected to the frame of the car 12 through the hinge 11. The gear is pressed using the clutch 13, and the position of the gears in the same level is achieved by the lever 14.

The electric train compressor drive works as follows. When the pressure in the pneumatic system of the electric train decreases, the electromagnetic controller 8 retracts the axis 9 and simultaneously drives the levers 10 and 14. The clutch 13 presses on the gear 4 until the protrusions on the gear coincide with the holes on the nozzle 7. At the same time, spring 6 is compressed. Gear 4 begins to move around its axis together with the wheel pair and drives gear 3, which in turn drives shaft 2 of compressor 1. When the pressure in the pneumatic system of the electric train increases to the required level, the electromagnetic controller 8 releases axis 9, and gear 4 under the action of spring 6 comes out of contact with nozzle 7 of the wheel pair. C 70 When the electric train is parked, a compressor driven by an electric motor is used. c The compressor drive of the electric train has a small number of parts, is easy to operate and maintain, and allows economical use of electricity.
