Specific embodiment

The utility model is described further with reference to the accompanying drawing.

Referring to Fig.1, the wear-resisting top glue of car high strength safe damper, including outer skeleton, outer skeletal internal it is columnar Yielding rubber 1, for through upper and lower axial aperture structure, outer skeleton includes being set in 1 top of yielding rubber at the axle center of yielding rubber 1 Outer seat board 2, the liner plate 3 being set in outside 1 lower part of yielding rubber, seat board 2, liner plate 3, which are equipped with, to coincide with 1 structure of yielding rubber Inner cavity, the inner cavity internal diameter of seat board 2 are less than the inner cavity internal diameter of liner plate 3, the outer diameter of the colloid of the yielding rubber on 11 top of boss structure Less than the colloid outer diameter of lower part, the circumferential surface of yielding rubber 1 forms the boss structure 11 of evagination, seat in seat board 2,3 joint of liner plate The lower end of plate 2 extends to the upper surface of boss structure 11, and prolongs along smooth horizontal outward in the upper surface of boss structure 11 For spread at seat board extension, the upper end of liner plate 3 extends to the lower surface of boss structure 11, and flat along the lower surface of boss structure 11 Sliding extension horizontal outward forms liner plate extension, and seat board extension, liner plate extension are bonded to be formed admittedly with respect to face contact Surely the fixed part 6 of glue is pushed up, fixed part 6 is set there are three the fixing bolt being uniformly distributed circumferentially, and boss structure 11 extends to seat board Between extension, liner plate extension, the thickness of boss structure 11 smoothly successively decreases from inside to outside, the setting of the thickness of boss structure 11 with Seat board extension, the structure goodness of fit of liner plate extension are higher, and the compactness of cooperation is stronger, and mutual supporting role is mentioned Height, yielding rubber are step column structure, and the cavity for the receiving yielding rubber that seat board, liner plate are constituted is to kiss with yielding rubber structure The step-like cavity closed, the upper and lower surface of the step structure of joint is corresponding to be bonded with seat board, liner plate corresponding position, boss structure It is combined into interference fit with seat board, matching for liner plate joint, seat board lower end, liner plate upper end are corresponding with the both ends of the surface of step structure to be connect Touching, forms direct impetus, and the supportive between outer skeleton and yielding rubber is greatly improved, when stress, seat board, lining Plate can unload power by yielding rubber at this, and equally, supporting role of the yielding rubber at this by outer skeleton is also stronger, mutually Effect improve, the dispersion effect of power improves, and the stress between outer skeleton, yielding rubber can pass through the impetus phase at boss structure Mutual diverging, force balance, outer skeleton form the package structure to yielding rubber, greatly improve the structural strength of top glue, Be bonded between yielding rubber 1 and seat board 2, liner plate 3, the top end face of yielding rubber 1 is equipped with ring-shaped distributed first protrusion 12, and first The top end face of protrusion 12 is bonded with the upper end inner wall of seat board 2, and the inside of the first protrusion 12 is equipped with ring-shaped distributed second protrusion 13, the height of the first protrusion 12 highly lower than the second protrusion 13, is equally spaced between multiple first protrusions 12, multiple second protrusions 13 Between be equally spaced, outer edge of first protrusion 12 close to the top end face of yielding rubber 1, the upper end-face edge of seat board 2 corresponding first The edge pressing structure 21 for covering the first protrusion 12, the top of the inner wall of edge pressing structure 21 and the first protrusion 12 are equipped at raised 12 positions End face joint is simultaneously bonded by glue, and centre bore, the top end face of the second protrusion 13 are equipped at the top end face center of yielding rubber 1 Connect with the top end face inner wall of yielding rubber 1 and be bonded, since the height of the second protrusion is higher than the height of the first protrusion, in order to match Structure is closed, is stepped ramp type structure at edge pressing structure 21, firstly, seat board, liner plate constitute the outer skeleton of split structure, assembling structure letter It is single, be conducive to the production, the assembly efficiency that improve top glue, full fixing and matching structure parcel-like formed to yielding rubber, to damping The protective effect of rubber is stronger, promotes to prolong the service life, secondly, the top of yielding rubber 1 passes through compartment distribution at two First protrusion, the second protrusion are contacted with seat board inner wall, cooperate the cooperation at boss structure with outer skeleton, yielding rubber and outer skeleton Between form three and directly put forth effort attachment point, the direct contact point between outer skeleton and yielding rubber is more, passes through impetus at three, load The impact of lotus timely transmitting mutual between yielding rubber, outer skeleton, diverging, producing balanced forces can avoid stress from concentrating, avoid Generate noise, improve the using effect of top glue, be step-like axis hole at the center of yielding rubber, the step structure of axis hole with subtract The step structure of shake rubber circumferential surface is at same position, and the upper end of yielding rubber passes through the first protrusion being spaced apart and seat board Upper end face contact, this kind of contact structures had both met the demand on the fit structure between yielding rubber and seat board, and matching at this It is combined into interference fit, seat board is more preferable to the fixation, supporting role, protective effect of yielding rubber, on the other hand, the of Disjunct distribution One convexes to form the support construction of suspension, and in stress, yielding rubber has a certain amount of buffering, deformation space at this, delays Stress is rushed, abnormal sound, the second protruding apex and seat board upper-end contact is avoided the occurrence of, plays the supporting role of auxiliary, complementary keeps away Exempt to generate abnormal sound, the main function of the second protrusion is, changes the structure of yielding rubber upper surface, makes yielding rubber in molding Its internal air can be overflowed by this, avoided generating rotten bubble in the circumferential surface of yielding rubber, improved the presentation quality of yielding rubber, Step-like structure facilitates the buffer itself of yielding rubber, avoids generating noise, whole to wrap up, while having and putting forth effort at three Point, stronger to stationarity, the supportive of yielding rubber, the structure of yielding rubber is greatly improved, and improves top glue Using effect, the inside of yielding rubber 1 are equipped with inner frame 4, and the center of inner frame 4 is equipped with through-hole, and the longitudinal section of inner frame 4 is U Type, inner frame are arranged at boss structure, and inner frame 4 supports inside inside provides, and reinforce structural rigidity, the knot of top glue entirety Structure intensity, promoting to push up glue has longer service life, and the structure of inner frame is easy to process, high production efficiency, at the same it is longitudinal, Internal supporting role laterally can be played, internal reinforcing effect is improved, 3 bottom of liner plate is equipped with bowl-shape shield bowl 5, protects bowl 5 top is connect with liner plate 3, and Open Side Down for shield bowl 5, and shield bowl 5 is convenient for connecting with the other component of damper.

The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model System, it is all according to any simple modification to the above embodiments in the technical essence of the utility model, equivalent variations, fall Enter within the protection scope of the utility model.
