Description

The invention relates to devices for damping oscillations, in particular, to hydraulic oscillation dampers installed on passenger railroad transport cars.

The purpose of the invention is to improve the reliability of the quencher by preventing suction 6 of the subcutaneous space of ambient air containing dust, abrasives, moisture, snow, which leads to wear and failure of the damper rod seal.

The drawing shows a hydraulic oscillation damper, a longitudinal section. - ..

   BUT ,

The hydraulic vibration damper contains a cylinder 1 with its seal 2 installed on the end face 2 of the rod 3, on which the piston 4 is fixed. The cylinder 1 is filled with a working fluid that is throttled through the calibrated orifice 5.

h

The rod 3 is connected to the casing 6 and the top head 7 connected to the non-moving frame 8 of the carriage.

On the casing 6 there is fixed a lid 9 with a seal 10, sealing it up 11. There is a damper fastening unit 12 with an over-5 spring rail 13 of the carriage mounted on the rod 11.

The casing 6 forms with the cylinder 1 a radial clearance 14, which communicates the rod 15 and the throat cavity 16.

The hydraulic damper operates 10 as follows.

During the course of stretching, the bolster 13 with the mounting unit 12 of the extinguisher 11 and the cylinder 1 is moved downward relative to the fixed 15 frame 8, the upper head 7, the rod 3 with the piston 4 and the casing 6 with the cover 9, the air rod 15 enters beef cavity 16.

Since the area of the stem 3 and the gi 11 20 are made equal to 4, the volume of the rod cavity 15 will increase as much as the volume of the traction cavity 16 decreases, which excludes the possibility of suction to the region of the rod 25 of the cavity 15, where air seal 2 is located harmful particles.

During the course of compression occurs reverse. stretching process.

Claims (1)

  1. A HYDRAULIC OSCILLATOR, containing a cylinder filled with a working fluid, a piston with a rod placed in it, a rod seal installed in one end of the cylinder, an absorber mount, connected to the other end of the cylinder, and a protective casing attached to the rod and covering the cylinder with a radial clearance , with the fact that, in order to increase reliability, the damper is equipped with a rod connecting the damper attachment unit to the cylinder end, and a lid attached to the casing with a seal that seals the rod.
