Yobretenie relates to vehicles, and in particular to hydraulic dampers of kolabadmin.Known hydraulic damper, comprising a housing in which is placed and clamped by the nut of the cylinder-piston group with valve devices. The body of the damper and the shaft is sealed with a sealing device. The shaft and housing have locking lugs that have rubber and metal bushings or ball bearings.Eyes with rod made in one piece (ed.St. N 541055, F 16 F 9/10, extinguishers Czechoslovak and German production, see reference: Sokolov M. M. Arava C. I. Levit, M. Absorbers rolling stock. M. Transport. 1985, S. 43 and 17) or welded (quencher firms GOD, see reference 35 C., ed. St. 514975, CL F 16 F 5/00, ed.St. N 1044859, CL F 16 F 5/00), or fasten the thread with locking elements (ed.St. N 1216485, CL F 16 F 5/00, extinguishers type KVZ-the Institute, the production of Hungary, see the Handbook, page 16-17). When these types of connection rod with eyelet lateral forces on the damper is rigidly transmitted to the elements of the packing gland stem seals and cause them to wear out more quickly. Lateral forces increase with the passage curves of small radii, arrows, and with increasing speed.Known hydrohalite, have to reduce side loads in eyelets fitted the. 16 F 19/08, extinguishers firms HORSES, see the Handbook, page 34). Tapered bushings allow the bias of the quencher to the 6obut wear out quickly and are destroyed due to cyclic radial loads without limiting device when the damper on the car in motion, and the ball bearings transmit high frequency vibrations through the damper from the effects of the path of the vehicle, wear and deform rollers mounting hydrohalides.All known hydrohalite not have devices to control fluid filling her without disassembly hydrohalides. Because of this, testing for the presence of fluid in hydrohalite and dressing can be made only in stationary conditions.Large side load on the seals and large radial load on the rubber sleeve lugs lead to rapid deterioration and loss of working fluid. Reduced working capacity of hydrohalides. Because of the impossibility of checking and topping-up of the working fluid hydrohalite unreliable in operation. As a consequence, increases the dynamic loading of vehicles, deteriorating the smoothness of the ride, the comfort of passengers, increased wear and tear of vehicles is about money (UK, application N 1447666, F 16 F 9/06, publ. 25.08.1986), comprising a housing (1) with a head (19) securing the cylinder-piston group with rod (5), passed through the guide (3) of the cylinder (2) and connected to the cylinder (18) of the mounting ring protrusions (I) and (3d), made at the ends of the guide (3), gasket (14) rod bearing rod seal, including internal (15A) and outer (15) of the ring. The outer ring is attached to the upper housing (1).A disadvantage of the known pneumatic-hydraulic shock absorber is hard hingeless connection rod (5) with screw (18) that if the distortions hydraulic shock absorbers creates significant lateral forces on the seal Assembly and leads to increased wear of sealing elements. Hence, the increase of the leakage of the working fluid and decreases the efficiency of the device. Known gidroaerotsentr has no devices for control and replenishment of the working fluid without complete disassembly, which reduces the operational reliability of the hydraulic shock absorbers and maintainability.The task of the invention is to improve the operational reliability of hydrohalides and his health by reducing stress on the seal elements and the introduction of devices that provide the residents of the housing, located in the cylinder-piston group with rod, passed through the guide cylinder with end of the annular protrusion, rod seal and bearing seal comprising inner retainer seal, and outer rings, of which the latter is attached to the upper part of the housing and the shaft and housing is equipped with eyelets.The new design is that the outer ring, fastening the casing is made of welded, and the connection of threaded rings has at the end hermetically closed plug screw pilot hole communicated with the annular cavity of the damper and the inner ring has at the end of the bottom two grooves forming the inner and outer flanges and the centering protrusion associated with additional and rod seals.Another design feature is that the eyelet of the rod with the head attached to the stem Rethimno through the roller, the axis of which is perpendicular to the axis of the lugs passing through rotating in the end groove of the head stock.Technical effect will be expressed as follows. Welded fastening of the outer ring to the body will increase the supporting rigidity of the inner ring (nut), and thread control fluid level, not looking absorbers, and, if necessary, and refueling. The presence on the lower end of the inner rings of the two grooves forming the outer and inner flanges and the centering protrusion covering the annular protrusion of the guide, in addition to the preload of the seal and centering of the cylinder-piston group relative to the body, will allow the design to carry out the control of the fluid level, but the bow shock, and, if necessary, and refill.This capability in design, thanks to the specified node changes, implemented by executing on the end face of the outer ring of the control openings, closed tightly threaded tube and communicated with the annular cavity of the Redeemer.Availability for one made with the eyelet head attached to the stem Rethimno through the roller, the axis of which is perpendicular to the axis of the lugs passing through rotating in the end groove of the head stock, eliminates the bias of supporting elements of the quencher reduces their wear and loss of the fluid and allows the replacement of a sealant on the stock.In Fig.1 shows a General view of hydrohalides; Fig.2, the node "A" in Fig.1.In case 1 razmyshlyayushiy 4 skipped the rod 6 with the piston 7. Bar 8 provided with a cylindrical head 9 attached to the rod Rethimno through the platen 10, the axis of which is perpendicular to the axis 11 of the lugs. The platen 10 is passed through the rod 6, rotating in a face groove 12 of the head.To the lower part of the body attached to the eyelet 13.Parallel walls of the groove 12 is limited to two cylindrical sections of the same slope, located in the same plane with the axis 11. In each of the lugs 8, 13 set separated by a bounding ring 14 of the elastic sleeve 15 fixed to the metal sleeve 16 retaining rings 17. Relative to the bushing 16 of the ring 14 mounted with a radial clearance.The housing has a bearing seals. It includes the United threaded inner 18 and outer ring 19. The outer ring to the upper part of the body attached to the welding seam 20 and has on the end hermetically closed by a threaded plug 21 pilot hole 22 provided with an annular cavity 23 of the Redeemer.The inner ring 18 has at the end of the bottom two grooves forming the outer 24 and inner flanges 25, and the centering protrusion 26 associated with an additional 27 and rod 28 seals.The threaded connection of the rings has elengy case 32 with a reinforcing flange 33.The damper works as follows.During movement of the vehicle lugs 8 and 13 perform oppositely directed motion, with small radius curves railway tracks distortions lugs 8 and 13 relative to each other are compensated by additional rotation of the rod 6 between the inclined located opposite the cylindrical sections of the groove 12 of the head 9. Additional compensation of such distortion will protect from destruction of the elastic sleeve 15 and will reduce the wear of the sealing elements of the damper and the possible loss for this reason, the working fluid, which ultimately will increase the operational reliability of the absorbers.To control the oil level in the damper lower part of the cover 32 is lifted up, Unscrew the ring threaded plug 21 and the measuring probe liquid level. At low level it up through the hole 22.Replacement of the seal 28 is as follows.Remove the clamp 31, the lower case 32, take out the cushion 10 and the cylinder 9 is separated from the stem, the screw 30 is released the bar 29 and the ring 18 vivencial, then replace the seal 28.Using the proposed hydrohalides will reduce DynamicData will decrease the wear of the rolling stock and rail track.The proposed hydrogasifier it is advisable to use leaf spring suspension cars, locomotives, wagons, electric rolling surface and underground transport, trams and cars.
