SU55600A1 - Device for increasing the traction force of a locomotive - Google Patents

Description

An increase in traction power and locomotive power is usually achieved by increasing the size of the boiler, the machine and the crew, which causes an increase in the weight of the parts (especially the boiler) and the total weight of the locomotive.

However, there is another known way to increase the traction force of a locomotive without increasing its weight, by using a device that is an endless chain that interacts with a track.

In the proposed device, in order to provide the greatest possible clarity and reliability of its operation, the links of such an endless chain are made in the form of spring pincers, which grab by the head of the additional rail laid between two strings of a normal rail track.

In FIG. 1 and 2 depict schematically a general view of the device (in two projections); FIG. 3 and 4 are partial views from above in FIG. one; FIG. 5-11 - details of the device (on a larger scale).

In a normal track gauge on leading ramps above 0.004

A third conventional type 4a rail was introduced, laid inside the track along its axis and screwed with screws to the same sleepers on which the main track rails rest. Above the axis of the third rail, at the extreme coupling axles, two gears 13 (Figs. 1, 2) are suspended to the locomotive frame, on which, like a caterpillar tractor belt, is worn a crawler chain 1. The gears 13 are driven from the adjacent axes of the locomotive.

The track 1 is suspended from the frame 2 of the locomotive by means of toothed rollers 5. The chain is made of plates (Figs. 5, 6) having two rows of 5 connected by axis 6. The pincers 7 are attached to the axis 6, which are used to grip the extension head rail and fitted with rollers 9 (fig. 3, 9) for rolling on plane 10 (fig. 11) of beam J5 connecting the track chain with the locomotive frame. In the normal position, the tongs 7 capture the rail head at the expense of the spring 11, which lies on the axis 6. The plates 4 are hinged with each other. The chain moves along the rollers in which the teeth enter the holes 12 of the plates 4 (Fig. 5). The rollers 9 (Fig. 3) are placed on the chain 1 in a checkerboard pattern. The axis of the rollers of the rest of the TC on ball bearings.

To drive the chains, there are designed gear wheels 13 installed at the ends, transferring the chain to the third rail and twin wheels 14, which automatically deflect the ends 8 of the levers of the pliers 7 to capture or release the rail head. The chain is connected to the locomotive frame by using a semi-ring beam 15, which forms the frame of the lower branch of the endless chain 1, along the plane 10 (Fig. 11) of which, as already mentioned, rolls 9, and rods 16 (Fig. 2), bar 15 with hydropneumatic presses 17, lying on the frame and carrying out tension between the locomotive frame and the additional rail.

To fit into the curves, the beam 15 is made of five links connected pivotally. The stability of the rods 16 is achieved by a cross connection 18 attached to the frame of the locomotive, and for the elasticity of the rods 16 is the spring 10 (Fig. 1, 2), laid at the junction of the rods 16 with the press rod 17.

The control of the track chain operation consists in lowering the gear 20 for connection with gear 21, as well as with gear 22 (FIGS. 1, 2, 4), which is on the same axis as the gear wheel 13, and in the start of compressed air or steam into the cylinders of the presses 17. Thus, the track chain is activated: at the discretion of the driver;

raising gear 20 stops the chain.

The operation of four presses 17 is supposed to have additional tension between the locomotive frame and the additional rail up to 10-12 tons at each point, and only 40-48 tons.

With the friction coefficient / g, the locomotive can additionally realize 8-10 tons of pulling force, in other words, a locomotive with a design pressure of 18 tons per coupling axis can have 26-28 tons of pressure on the coupling axis and, accordingly, the tangential pulling force.

The subject matter of the invention.
