Abstract
The utility model discloses an oil-leakage prevention hydraulic damping bush, which consists of an inner pipe (1), a supporting frame (4), a rubber main spring vulcanized from a rubber body (6), a limiter (2) and a buffer block (3) and an outer pipe (5). At least two sealing ribs (7) are respectively arranged at two ends of the rubber main spring. According to the above technical scheme, the oil-leakage prevention hydraulic damping bush is simple in structure and adopts a structures of two layers of the sealing ribs and a step and inclined plane locking structure, and accordingly, oil cannot be leaked from the bush on the condition that the hydraulic bush is stressed by axial load, radial load, torsion load and the like, and the problem of abnormal sounds is avoided. Further, high damping and high rigidity are guaranteed when an engine runs at low frequency and in large amplitude, excellent vibration isolation effect and damping effect are realized for automobiles and the service life of the oil-leakage prevention hydraulic damping bush is prolonged.
Description
Technical field
The utility model relates to a kind of leakproof fluid pressure drag Buddhist nun lining.
Background technique
What traditional hydraulic damping lining product adopted is whole cylndrical surface locking structure, the hydraulic damping lining of this structure is easy to cause leakage, cause life of product short, therefore big damping and big rigidity can not be provided, the leakage problem is a knotty problem of hydraulic damping lining product always, its characteristic feature shows as abnormal sound, and failure mode is not for providing big damping and big rigidity, and consequence directly influences the NVH performance of automobile.
The model utility content
Problem to be solved in the utility model provides a kind of leakproof fluid pressure drag Buddhist nun lining, its objective is to prevent that the leakage of oil problem from use appearring in the hydraulic damping lining.
To achieve these goals, the technological scheme taked of the utility model is:
This leakproof fluid provided by the utility model is pressed lining, a kind of leakproof fluid pressure drag Buddhist nun lining, comprise by rubber spring, limiting stopper, buffer stopper and the outer tube of interior pipe, support frame and rubber body sulfuration, be respectively equipped with at least two sealed muscles at the two ends of described rubber spring.
Described rubber spring and outer tube interference fit make the outer tube two ends form step and inclined-plane respectively.
The angular range on described inclined-plane is 4 °～8 °.
Adopt technique scheme, this leakproof fluid pressure drag Buddhist nun lining provided by the utility model, simple in structure, adopt double-layer seal muscle structure, step and inclined-plane locking mechanism, guaranteed hydraulic bushing be subjected to axially, radially, reverse etc. under the situation of load, liquid that can not spills from lining, thereby avoided the generation of situations such as abnormal sound, guaranteed that motor can provide big damping, big rigidity when low frequency, large amplitude, for automobile provides good vibration isolation, effectiveness in vibration suppression and the working life of having improved product.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model rubber spring.
Be labeled as among the figure:
1, interior pipe, 2, limiting stopper, 3, buffer stopper, 4, support frame, 5, outer tube, 6, rubber body, 7, sealed muscle.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize preventing that the leakage of oil problem from use appearring in the hydraulic damping lining.The technological scheme that the utility model is taked is:
Extremely shown in Figure 2 as Fig. 1, this leakproof fluid pressure drag Buddhist nun lining provided by the utility model, comprise by rubber spring, limiting stopper 2, buffer stopper 3 and the outer tube 5 of interior pipe 1, support frame 4 and rubber body 6 sulfurations, be respectively equipped with at least two sealed muscles 7 at the two ends of rubber spring.
Rubber spring and outer tube 5 interference fit make outer tube 5 two ends form step and inclined-plane respectively.
The angular range on described inclined-plane is 4 °～8 °.
Adopt technique scheme, this leakproof fluid pressure drag Buddhist nun lining, rubber spring by interior pipe 1, support frame 4 and rubber body 6 sulfurations, be provided with two sealed muscles 7 at the two ends of rubber spring, it is of a size of 1mm*0.25mm, in damp liquid, rubber spring is pressed into outer tube 5 with the magnitude of interference of monolateral 0.1mm, make rubber spring and outer tube interference fit, so just formed that there is the step of a 0.15mm at outer tube 5 two ends apart from end face 15mm place and apart from the inclined-plane at end face 5mm place, its angle is 6 °, has so just formed step locking and inclined-plane locking mechanism.Guaranteed hydraulic bushing be subjected to axially, radially, reverse etc. under the situation of load, liquid that can not spills from lining, thereby avoided the generation of situations such as abnormal sound, guaranteed that motor can provide big damping, big rigidity when low frequency, large amplitude, for automobile provides good vibration isolation, effectiveness in vibration suppression and the working life of having improved product.
The technological scheme that the utility model adopted compared with prior art, has tangible difference, possessed substantial characteristics, and obtained progress technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicability.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
