Description
Technical field
The present invention relates to automobile lining technical field, particularly relate to a kind of automobile bushing and preparation method thereof.
Background technology
Suspension is actually by connecting rod, and bumper and damping spring form.Multi link hangs, as its name suggests, the connecting rod being exactly him is more some more than general suspension, as usual, general all the suspension of 4 connecting rods or more bar linkage structure, be called multi link, reduce the vibration of road surface to chassis by being flexible coupling between many connecting rods, thus reach the object of damping, owing to there being multiple connecting rod, the lining of such connection connecting rod all can produce larger angle change in the process of relative motion, at this moment, a kind ofly possesses lower torsion with regard to needing and is connected with the lining of higher-strength.
In bush structure traditional at present design: originally reaming or diameter reducing process mounting structure cannot adapt to new production technology demand, novel opening lining can meet the requirement of the operating mode that becomes increasingly complex and the more and more higher aspect such as traveling comfort, operability, NVH of people.Under the prerequisite that design space requires, we need to design a kind of new structure to the requirement meeting client and constantly promote travelling comfort, manipulation stability is the original intention that we design.Existing product structure designs and now cannot reach requirement, and adopts new structure can meet working condition requirement, and its technology is also that we need research and grasp, and in prior art, inner-outer sleeve structure, cannot provide low torsional stiffness, needs undergauge operation; With needs reaming undergauge operation.
Summary of the invention
In view of this, be necessary to provide a kind of manufacturing process simple, and strong automobile bushing of low torsional stiffness and preparation method thereof.
The present invention realizes like this, a kind of automobile bushing, comprise inner sleeve, middle cover, overcoat and rubber layer, described inner sleeve, middle cover, overcoat is cylindric, described inner sleeve is in middle cover, described middle cover is in overcoat, and described inner sleeve, middle cover and overcoat coaxial, rubber layer described in one deck is provided with between described inner sleeve and middle cover, also rubber layer described in one deck is provided with between described middle cover and overcoat, described rubber layer is fixed between inner sleeve and middle cover and between middle cover and overcoat by the mode of sulfuration, the wall of described middle cover and overcoat is equipped with opening, middle cover and the opening put outward are in the same side, and on rubber layer in correspondence cover and outward the opening part that puts also be provided with the second opening, the edge of opening and the second opening flushes.
Present invention also offers the method for making of above-mentioned automobile bushing, comprise the following steps:
Step one: make overcoat;
According to design paper, choose lightweight high-intensity material, directly use degreasing process to make overcoat, and pluck out opening by the wall of overcoat;
Step 2: overlap in making;
According to design paper, choose lightweight high-intensity material, cover in directly using degreasing ball blast technique to make, and pluck out opening by the wall of middle cover;
Step 3: make inner sleeve;
According to design paper, choose lightweight high-intensity material, directly use degreasing process to make inner sleeve;
Step 4: install inner sleeve and middle cover;
Inner sleeve be enclosed within middle cover, inner sleeve and middle cover adopt fastening by the mode of sulfuration, make to be full of one deck rubber layer between inner sleeve and middle cover;
Step 5: install overcoat;
Overcoat is enclosed within middle cover peripheral, and the opening that overcoat puts in being enclosed within is in the same side, by the mode of sulfuration, by overcoat and middle cover fastening, make to be full of one deck rubber layer between overcoat and middle cover, rubber layer plucks out the second opening near opening part, the edge polishing of opening and the second opening is flushed.
The advantage of a kind of automobile bushing provided by the invention and preparation method thereof is: the present invention is simple and reasonable, by arranging opening on middle cover and outer cover, do not need the undergauge operation in traditional handicraft and reaming undergauge operation, technique is simple, the present invention can not only meet the restriction of conventional confguration, and reduction manufacturing cost, enhance competitiveness.
