Abstract

The utility model discloses a hydraulic damper, which comprises a working cylinder, a piston rod and a piston. The upper end of the working cylinder is provided with an end cover. An oil storage cylinder is further equipped on the outer side of the working cylinder. Hydraulic oil is filled in the working cylinder and the oil storage cylinder. A bottom valve is equipped on the bottom of the working cylinder. A magnet is equipped on the bottom valve. By equipping the magnet inside the working cylinder, the hydraulic damper provided in the utility model is enabled to absorb the fine iron powder generated by the wearing of the working cylinder through the magnet and thus keep the hydraulic oil inside the oil storage cylinder clean. The wearing generated between the piston and the inner wall of the working cylinder when the piston is performing reciprocating motion inside the working cylinder along the inner wall of the working cylinder is then alleviated. The wearing problem of the working cylinder is relatively well solved. Meanwhile, the flowing smoothness of the hydraulic oil is ensured due to the fact that the hydraulic oil is clear after the fine iron powder is absorbed. The stability of the damper is guaranteed. The comfort level of a vehicle is improved.

Description

A kind of hydraulic damper
Technical field
The utility model relates to a kind of automobile and motorcycle and uses shock-absorption device, particularly a kind of hydraulic damper.
Background technique
The vibration damper of automobile use at present all belongs to its main structure of hydraulic damper basically and comprises parts such as clutch release slave cylinder, piston, guiding device, oil storage cylinder.These parts are coaxial layout.Its principle is, from the impact and the vibrations on road surface, the transmission through cylinder body makes piston reciprocating with respect to clutch release slave cylinder in clutch release slave cylinder, comes in the Control work cylinder flowing of hydraulic oil to realize damping shock absorption by being arranged on compression valve and rebuilt valve on the piston.But clutch release slave cylinder is a thin-walled, and long tube is gone, and its manufacturing process is poor, and wearing layer hardness is also low and wearing layer thin.When clutch release slave cylinder may wear to a certain extent; The gap appears in piston and clutch release slave cylinder inwall, and piston hydraulic oil seepage has between the upper and lower directly influenced damping performance; And piston rod is produced at work wave; This waves the wearing and tearing increase that makes piston and inboard wall of cylinder block conversely again, and influence finally can cause vibration damper to be scrapped so repeatedly.Therefore, the wearing and tearing of clutch release slave cylinder are the first causes that causes vibration damper to be scrapped, and the wearing and tearing that how to solve clutch release slave cylinder become problem anxious to be solved.
The model utility content
The purpose of the utility model is in order to overcome the problems referred to above, a kind of hydraulic damper to be provided.
For achieving the above object, the method that the utility model adopts is: a kind of hydraulic damper comprises clutch release slave cylinder; Piston rod and piston; Be provided with end cap in the clutch release slave cylinder upper end, also be provided with an oil storage cylinder, in clutch release slave cylinder and oil storage cylinder, be provided with hydraulic oil in the outside of clutch release slave cylinder; Bottom at clutch release slave cylinder is provided with bottom valve, on described bottom valve, is provided with magnet.
As a kind of improvement of the utility model, be provided with oil sealing at described end cap and piston rod joint.
As a kind of improvement of the utility model, described piston rod is provided with buffer stopper.
A kind of improvement as the utility model is provided with seal ring between described end cap and clutch release slave cylinder.
The beneficial effect of the utility model is:
The utility model is through being provided with magnet in clutch release slave cylinder, through magnet the clutch release slave cylinder thin iron powder that gets off that weares and teares is adsorbed, and the hydraulic oil in the oil storage cylinder is kept clean.Thereby alleviated piston in clutch release slave cylinder along the clutch release slave cylinder inwall when reciprocating and the wearing and tearing of clutch release slave cylinder inwall; Solved the clutch release slave cylinder wear problems preferably; Simultaneously because hydraulic oil seems limpid after adsorbing thin iron powder through magnet; Guarantee the mobile smoothness of hydraulic oil, guaranteed the stability of vibration damper, improved the comfort level of car.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein each parts is:
1 end cap, 2 buffer stoppers
3 hydraulic oil, 4 oil storage cylinders
5 bottom valves, 6 magnet
7 clutch release slave cylinders, 8 pistons
9 seal rings, 10 oil sealings
11 piston rods.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described;
Like the described a kind of hydraulic damper of Fig. 1; Comprise clutch release slave cylinder 7, piston rod 11 and piston 8 are provided with end cap 1 in clutch release slave cylinder 7 upper ends; Also be provided with an oil storage cylinder 4 in the outside of clutch release slave cylinder 7; In clutch release slave cylinder 7 and oil storage cylinder 4, be provided with hydraulic oil 3, be provided with bottom valve 5, on described bottom valve 5, be provided with magnet 6 in the bottom of clutch release slave cylinder 7.
The utility model discloses a kind of a kind of improvement of hydraulic damper, be provided with oil sealing 10 with piston rod 11 joints at described end cap 1.
The utility model discloses a kind of a kind of improvement of hydraulic damper, described piston rod 11 is provided with buffer stopper 2.
The utility model discloses a kind of a kind of improvement of hydraulic damper, between described end cap 1 and clutch release slave cylinder 7, be provided with seal ring 9.
The utility model is through being provided with magnet in clutch release slave cylinder, through magnet the clutch release slave cylinder thin iron powder that gets off that weares and teares is adsorbed, and the hydraulic oil in the oil storage cylinder is kept clean.Thereby alleviated piston in clutch release slave cylinder along the clutch release slave cylinder inwall when reciprocating and the wearing and tearing of clutch release slave cylinder inwall; Solved the clutch release slave cylinder wear problems preferably; Simultaneously because hydraulic oil seems limpid after adsorbing thin iron powder through magnet; Guarantee the mobile smoothness of hydraulic oil, guaranteed the stability of vibration damper, improved the comfort level of car.
The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
