Abstract
The utility model relates to the technical field of vehicle accessories, concretely relates to a foam type vibration isolator, characterized in that: the foam type vibration isolator comprises an inner cylinder, a piston arranged in the inner cylinder, a connection rod with an inner end connected with the piston, a bottom valve arranged on one end of the inner cylinder, a guide device arranged on another end of the inner cylinder and an oil seal arranged at the outer side of the guide device, wherein an oil storage cylinder is arranged at the outer side of the inner cylinder, a EVA plastic foam layer is arranged in the oil storage cylinder and wound at the outer side of the inner cylinder, the EVA plastic foam layer is a special composite foam introduced from abroad. The foam type vibration isolator has features of quick heat dissipation of the vibration isolator, reduced noise, prevention of the foaming behavior of the oil, increased self-continuity, ensured vehicle comfort, vehicle-through property, safety, saved fuel, energy saving and environmental protection.
Description
Technical field
The utility model relates to the auto parts machinery field, is specifically related to a kind of foam version vibration damper.
Background technique
The prior oscillating damper employing charges into nitrogen and is used for buffering between clutch release slave cylinder and oil storage cylinder, low-pressure nitrogen is between clutch release slave cylinder and oil storage cylinder, so nitrogen acts directly on the liquid level of shock absorber oil, indirectly-acting is in the piston rod of vibration damper, show as the gas rebounding force, because the heat radiation of nitrogen is bad, be easy to generate shortcomings such as foam and loss, cause the continuity of vibration damper operation to be obstructed, problems such as easily aging and damage, sealability requires very strict simultaneously, the machining accuracy height, the cost of production height, the vibration damper controllable damping little and under dither effectiveness in vibration suppression undesirable.
Summary of the invention
The purpose of this utility model provides a kind of foam version vibration damper, this vibration damper rapid heat dissipation, oil resistant, resistance to compression.
A kind of foam version vibration damper, it is characterized in that: by inner casing, be located at piston in the inner casing, inner connecting rod, the bottom valve of being located at inner casing one end, the guider of being located at the inner casing the other end that links to each other with piston, the oil sealing be located at outside the guider forms, the described inner casing outside is provided with oil storage cylinder, be provided with EVA plastic foam layer in the described oil storage cylinder, described EVA plastic foam layer is set around the inner casing outside, and described EVA plastic foam layer is the external special composite foam of introducing.
Described piston is provided with throttle orifice, makes that the oil in two-part space that inner casing separated by piston can complement each other, and described inner casing communicates with oil storage cylinder, and the in-out end of described connecting rod is arranged with dust-proof cover, and the oil storage cylinder two ends are respectively established and are welded with a connecting seat.
Owing to be provided with said structure, this vibration damper rapid heat dissipation, reduction noise, grease proofing generation foamed effect improve the continuity of self, have ensured the travelling comfort of vehicle body, car, Security excessively, and fuel-efficient, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural representation of a kind of foam version of the utility model vibration damper.
Embodiment
As shown in Figure 1, a kind of foam version vibration damper, it is characterized in that: by inner casing 1, be located at the piston 2 in the inner casing 1, inner connecting rod 3, the bottom valve 4 of being located at inner casing 1 one ends, the guider 5 of being located at inner casing 1 the other end that links to each other with piston 2, the oil sealing 6 of being located at guider 5 outsides and form, described inner casing 1 outside is provided with oil storage cylinder 7, be provided with EVA plastic foam layer 71 in the described oil storage cylinder 7, described EVA plastic foam layer 71 is set around inner casing 1 outside, described EVA plastic foam layer 71 is the external special composite foam of introducing, and has characteristics such as oil resistant, high temperature resistant, resistance to compression, good heat dissipation.Described piston 2 is provided with throttle orifice 21, makes that the oil in two-part space that inner casing 1 separated by piston can complement each other, and described inner casing 1 communicates with oil storage cylinder 7.The in-out end of described connecting rod 3 is arranged with dust-proof cover, and oil storage cylinder 7 two ends are respectively established and are welded with a connecting seat 8.This use is novel following characteristics: 1. because eva foam has the advantage of rapid heat dissipation, can reduce the rate of climb of center housing temperature, improve vibration damper working life.2. because eva foam has the advantage of oil resistant, can grease proofing generation foamed, improve the continuity of shock absorber piston rod operation, reduce the operating noise of vibration damper, ensured travelling comfort, the Security of vehicle body.3. eva foam can better ensure the continuity of shock absorber piston rod operation, thereby has improved the power factor of the useful work of vibration damper operation, fuel-efficient environmental protection.
