SU13209A1 - Adaptation to the handbrake of railway rolling stock to limit the force of the brake pads on the wheel bandages - Google Patents

Description

The proposed offer is a special feature. To the hand brake of the rolling stock, the railway composition has the purpose to limit the force of the brake pads on the tires of the wheels to the desired value. Adaptation, on condition of preserving the brake lever, generally known construction, is identified on the Cher, tezhe, where thebes. 1 shows a side view of a brake with shaft mounting with its proposed adaptation; FIG. 2- “top view of the face with the same iris arrangement; FIG. 3 - ratchet wheel; FIG. 4-6 General view of the spring dynamometer; FIG. 5-section hydraulic power meter.

The upper part of the handbrake of a normal boxcar shown in FIG. 1, 2, consisting of a handle J and a vertical shaft 2, and placed in podshishnikami- 3, supplemented with a handle device A. By means of parts (clamps). The S.S handle freely connects to the 4 5 ratchet mechanism (storage wheel), which, in turn,

mounted on a vertical shaft S

between the handle. brake 1 and bearing

shaft D and using bolts-6 and 6 and rings

7 is skirted into one piece by a shaft 2. Py. Cloth A consists of two parts-handle

. and two, fastened with rivets, 9 clamps 8 and 8,. Both of them are with each other with pngarn 17 On the projecting part

, clamp 8 is fixed. an axis 14, on which the doggie 15 is mounted, is held in position by a spring 16. On the axis, the second doggie 19 is mounted, the long arm of which rests on the spring 21, which is manually adjustable by a screw 22. The short shoulder of the same dog rests on the finger .8, connected by means of a hinge 23 with a handle 8. To hold the finger 18 in a locked state with the short arm of the pawl 19, the handle 8 is provided with a spring. Installing handle A on shaft 2 must be done without removing handle 1, for which

the stored Ko.) ieco 4 has a detachable part 5 (fig. o), which, after the installation of the ratchet.

is fastened in place with the bolt 6 rod. Clamps, which fit freely on the pins of the ratchet wheel 4, have the same detachable parts 10 and 10, which, after being mounted on the ratchet wheel, are inserted into the place and held 10 1s in their places with a strap and check 28. Thus Before starting the braking, the vertical shaft 2 is rotated using the handle 1 and this handle A does not rotate. At the beginning of the braking, by turning the handle L, the Jfo pushes the ratchet wheel and the further action of the device

It is based on the failure of the clutch of the short arm of a dog; 19 with a finger 8, as soon as the pressure of the brake pads on the tires of the wheels exceeds the required calculated force.
