Abstract

This invention relates to railway transport. The purpose of the invention is to simplify the design, reducing the complexity of manufacturing. The braking lever gear of a four-axle bogie consists of two biaxial carriages connected by a connecting beam 1, having a central heel 2 and longitudinal slits 5 for accommodating a device transmitting the braking force from the driving rod to the lever gear of a further pair of axles. The said device is designed as a bracket 14 located inside the beam 1, one end of which goes through the slot 5 to the top of the beam 1, rests on it through the bearings and is connected to the leading thrust 13, the other end of the bracket 13 is connected to the driving lever for long distance transmission pairs of axes. 3 il.

The invention relates to railway transport and can be used in the construction of multi-axle carriages.

The purpose of the invention is to simplify the design and reduce the complexity of manufacturing.

Figure 1 shows a diagram of the lever brake transmission of a four-axle railway carriage, side view; FIG. 2 —a-A section in FIG. 1: in FIG. 3 - section BB in FIG. 1.

The design includes brake transmissions of two serial biaxial carriages, interconnected by a connecting beam 1, having a central heel 2, reinforced inside the beam by transverse diaphragms 3 and 4. The upper and lower beams of the beam have on either side of the bird longitudinal slots 5 and 6 Designed trolleys for placing bypass arms. In construction, these slots are also used to accommodate elements of the lever transmission. In general, the braking gear includes vertical levers 7 mounted on each two-axle bogie, connected with dead-point brackets by pulls 8. Vertical drive levers 9 and 10 are connected with levers 7 by spacers 11. The lever gears of two-axle bogies are connected in parallel by distribution lever 12 connected with the driving lever 10 of the first carriage directly, and with the driving lever 9 of the second carriage through the driving rod 13 and the bracket 14. The flat bracket 14 is oriented along the carriage and located inside connect flax beams under the air. The lateral diaphragms 3 and 4 (Fig. 2 and 3), which reinforce the plenary, are provided with windows 15 and 16, respectively, which are used to receive the staples 14 through them. The coupling rod 13 and the staple 14 are connected by means of a swivel roller 17. is supported on the connecting beam 1 through bearings 18. Sliding bearings can be used in this support. When assembling the cart, the bracket 14 is inserted into the beam 1 through the lower longitudinal slot in the beam.

Lever gear works as follows.

When the car is braked, the force from the brake cylinder is transmitted to the lever 12 via the car trailer. This lever distributes the total braking force to the near

biaxial trolley, acting directly on the lever 10, and on the distant biaxial trolley - through the driving gear 13, the bracket 14 on the lever 9. Under the action of this force within the gaps in the lever gear, as well as

wear of the shoes and wheels of the cart bracket 14 freely moves along the cart on bearings 18 along the slits of the beam and in the windows of the diaphragms 3 and 4, ensuring the normal functioning of the cart brake - pressing the pad against the wheels and releasing the brake.
