Abstract
The utility model discloses a loader gearbox triaxial assembly draining device, it includes hydro -cylinder, piston, friction disc subassembly, dish spring and draining hole, establish on the piston in the draining hole. This structure loader gearbox triaxial assembly draining device has operation high efficiency, the preparation and the running cost is low, equipment long service life's advantage of shifting, solved current loader gearbox triaxial assembly draining hole pressure release open in usual lead to keeping off the position build press chronicly so that shift chronic, cause the friction disc to damage and the dead problem of triaxial assembly card.
Description
Technical field
This utility model relates to loader planet row type change speed gear box three axle assembly structure, is specifically related to 5 tons of Wheel type loader transmission case three axle assembly drainage devices.
Background technology
5 tons of wheel loader planet row type change speed gear boxes, because of the cost performance that its maintainability is good, reliability is high and good, are the most still widely adopted；Three axle assemblies in change speed gear box, the combinative structure of commonly used friction plate assembly, oil cylinder and piston, enter oil cylinder pushing piston by gear pressure oil, thus pressing friction chip module realizes moment of torsion transmission；In gear handoff procedure, for ensureing the smooth disengagement of piston and friction plate assembly, it is desirable to oil in-cylinder pressure oil can depart to realize gear rapidly in pressure release.Three axle assembly drainage devices are commonly used in the market is located at pressure release oilhole on oil cylinder, and it is oilhole open in usual, this structure drainage device is in gear work process, oil leak hole open in usual is let out in causing gear oil pressure, cause gear to build pressure time length and then shift time is long, cause friction plate to damage, three axle assembly cards are waited indefinitely fault.
Summary of the invention
The purpose of this utility model be to provide a kind of gear shift operation rapidly and efficiently, make and operating cost is low, the loading machine gearbox of service life of equipment length three axle assembly drainage device, solve the oil leak hole open in usual pressure release of existing loading machine gearbox three axle assembly and cause gear to build pressure time length and then shift time length, cause the problem that friction plate damages and three axle assemblies are stuck.
For achieving the above object, this utility model loading machine gearbox three axle assembly drainage device includes oil cylinder, piston, friction plate assembly, disc spring and oil leak hole；Described oil leak hole is located on piston.
Said structure loading machine gearbox three axle assembly drainage device is located on piston by the oil leak hole open in usual on oil cylinder being changed, in shift process, pressure oil enters oil cylinder pushing piston and moves toward friction plate assembly, until pressing friction chip module, now the oil leak hole on piston is blocked by friction plate assembly, it is achieved oil leak hole closes thus ensures pressure；During gearshift, gear oil no longer works, and by the return effect of the disc spring on piston, promotes piston to separate with friction plate assembly, and oil leak hole reopens, it is achieved draining, it is ensured that separate thoroughly.
The design of above-mentioned loading machine gearbox three axle assembly drainage device structure has the following characteristics that
1, by oil leak hole by being changed to piston on oil cylinder, piston be ironcasting, oil cylinder be forging, ironcasting hardness is low, and oil leak hole is easily worked, tool life, saves cutter expense；
2, oil leak hole is on piston, and when gear works, piston pressing friction chip module, it is possible to realize the Guan Bi of oil leak hole, it is ensured that gear pressure oil does not leaks, complete machine operating is more steady, reduces the fault of three axle assemblies；
3, oil leak hole is on piston, and when gear separates, due to the effect of return disc spring, oil leak hole is opened, and forces draining, and is injected directly to by oil on friction plate assembly, friction plate assembly plays forced feed lubrication effect, can reduce the fault of friction plate assembly.
Use above-mentioned loading machine gearbox three axle assembly drainage device, can solve the problem that planet row type change speed gear box three axle assembly is in gear work process, oil leak hole open in usual is let out in causing gear oil pressure, cause gear to build pressure time length and then shift time is long, cause the problem that friction plate damages, three axle assemblies are stuck, additionally, force draining friction plate can be played lubricant effect, extend the service life of friction plate, reduce equipment operation maintenance expense.
Accompanying drawing explanation
Accompanying drawing is this utility model loading machine gearbox three axle assembly main cross-sectional schematic of drainage device structure.
Reference: oil cylinder 1, piston 2, friction plate assembly 3, disc spring 4 and oil leak hole 5.
Detailed description of the invention
With detailed description of the invention, this utility model loading machine gearbox three axle assembly drainage device is described in further detail below in conjunction with the accompanying drawings.
Loading machine gearbox three axle assembly drainage device includes oil cylinder 1, piston 2, friction plate assembly 3, disc spring 4 and oil leak hole 5 as shown in drawings；Described oil leak hole 5 sets on the piston 2.
In shift process, pressure oil enters oil cylinder 1, promotes piston 2 to move toward friction plate assembly 3, until pressing friction chip module 3, now the oil leak hole 5 on piston 2 is blocked by friction plate assembly 3, it is achieved oil leak hole 5 closes, it is ensured that pressure.During gearshift, gear oil no longer works, and by the return effect of the disc spring 4 on piston 2, promotes piston 2 to separate with friction plate assembly 3, and oil leak hole 5 reopens, it is achieved draining, it is ensured that separate thoroughly.
Oil leak hole 5 sets and can reduce machining of oil hole cost on the piston 2, ensure after compression that pressure oil will not leak, and can play again the effect of forced feed lubrication simultaneously, improve three axle assembly reliabilities friction plate assembly 3 during pressure release, reduce product fault after sale, reduce three guarantees expense.
