Abstract
The utility model discloses an oil pressure damper which comprises a piston rod, a working cylinder and an oil storage cylinder that are arranged in a coaxial way; the lower part of the working cylinder is provided with a compression valve and a compensation valve; the lower part of the piston rod is provided with a piston, a rebound valve and a circulating valve; the top of the working cylinder is provided with a guide seat and an oil seal; the top of the oil storage cylinder is provided with a dustproof cover; the upper part and the lower part of the working cylinder are respectively provided with a filter screen; and the filter screen is evenly provided with magnet. The oil pressure damper can absorb scrap iron so as to keep damping oil clean, is prevented from being rapidly worn by the scrap iron, so the service life of the damper is prolonged and the damper has a good working state.
Description
Technical field
The utility model relates to the vibration damper field, relates in particular to a kind of oleo-gear.
Background technique
Oleo-gear is one of vibration damper of using always, traditional oleo-gear, and after using a period of time, the clutch release slave cylinder inwall is because friction, a lot of iron filings that can come off, iron filings are mingled in the damping oil, make damping oil muddy.After iron filings increased, vibration damper was when work, and piston rod moves up and down, and piston and clutch release slave cylinder friction have iron filings on the frictional contact surface, can accelerate the wearing and tearing of clutch release slave cylinder inwall, finally cause defective shock absorber.
Summary of the invention
In order to solve the problem of above existence, the utility model discloses a kind of oleo-gear.This oleo-gear can keep the damping oil cleaning with the absorption of the iron filings in the vibration damper, slows down the clutch release slave cylinder wearing and tearing, prolongs the working life of vibration damper.
This oleo-gear; The piston rod, clutch release slave cylinder and the oil storage cylinder that comprise coaxial setting; The clutch release slave cylinder bottom is provided with compression valve and recuperation valve, and the bottom of piston rod is provided with piston, rebound valve and flowing valve, and the top of clutch release slave cylinder is provided with guide holder and oil sealing; The top of oil storage cylinder is provided with dust-proof cover, and the clutch release slave cylinder upper and lower is respectively arranged with filter screen.
Evenly be furnished with magnet on the filter screen.
Filter screen is plastics or ferrous material.
During vibration damper work, because wall friction in piston and the clutch release slave cylinder can produce iron filings; Iron filings get into damping oil, and are filtered online magnet absorption, and damping oil is kept clean; Avoided accelerating the fretting wear of piston and clutch release slave cylinder inwall, made vibration damper keep working state preferably because of iron filings.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Accompanying drawing is indicated tabulation: 1-dust-proof cover, 2-piston rod, 3-guide holder, 4-clutch release slave cylinder, 5-flowing valve, 6-recuperation valve, 7-compression valve, 8-oil storage cylinder, 9-rebound valve, 10-filter screen, 11-magnet.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further illustrate the utility model.
As shown in Figure 1, this oleo-gear comprises piston rod 2, clutch release slave cylinder 4 and the oil storage cylinder 8 of coaxial setting; Clutch release slave cylinder 4 bottoms are provided with compression valve 7 and recuperation valve 6; The bottom of piston rod 2 is provided with piston, rebound valve 9 and flowing valve 5, and the top of clutch release slave cylinder 4 is provided with guide holder 3 and oil sealing, and the top of oil storage cylinder 8 is provided with dust-proof cover 1; Clutch release slave cylinder 4 upper and lowers are respectively arranged with filter screen 10, evenly are furnished with magnet 11 on the filter screen 10.
The working principle of oleo-gear is, when relative movement appearred in vibrations between vehicle body and vehicle bridge, the piston in the vibration damper moved up and down, and the damping oil in the vibration damper clutch release slave cylinder flows in another chamber through different holes from a chamber repeatedly.The intermolecular interior friction of friction between hole wall and damping oil and fluid at this moment forms damping force to vibrations, and making the thump Conversion of energy is damping oil heat energy, is dispersed in the atmosphere by the vibration damper absorption again.
Produce iron filings in the friction process, iron filings are mixed in the damping oil, can influence the degree of wear in the friction process.The filter screen 10 that has magnet 11 in the utility model can keep the damping oil cleaning with the absorption of the iron filings in the vibration damper, avoids accelerating fretting wear because of iron filings, prolongs the life-span of vibration damper, makes vibration damper that working state preferably arranged.
Claims (3)
1. oleo-gear; The piston rod, clutch release slave cylinder and the oil storage cylinder that comprise coaxial setting; The clutch release slave cylinder bottom is provided with compression valve and recuperation valve, and the bottom of piston rod is provided with piston, rebound valve and flowing valve, and the top of clutch release slave cylinder is provided with guide holder and oil sealing; The top of oil storage cylinder is provided with dust-proof cover, it is characterized in that the clutch release slave cylinder upper and lower is respectively arranged with filter screen.
