Description

Car high strength safe damper top connecting assembly

Technical field

The utility model belongs to automobile absorber technical field, and in particular to car is connected on high strength safe damper Assembly.

Background technique

Damper (Absorber), be for inhibit after spring shock-absorbing rebound when concussion and from the impact on road surface.Extensively It is general be used for automobile, for accelerate vehicle frame and body vibrations decaying, to improve ride of vehicle.Passing through uneven road surface When, although shock-absorbing spring can filter the vibration on road surface, spring itself also has reciprocating motion, and damper is exactly for pressing down Make this spring jump.

The connection of damper upper end and vehicle body needs to use terminal pad, as the tie point of damper and vehicle body, upper company It connecing disk and needs to absorb the alternating shock load from road surface, one end of upper terminal pad connects damper, and the other end connects vehicle body, on The structural strength of terminal pad determines the service life of terminal pad, the service performance of automobile absorber.Existing upper terminal pad Structure that rubber is set, the connection knot of skeleton and rubber are surrounded between tubular inner frame, outer skeleton and inner frame for skeleton outside tubular Structure is too simple, and the stress load of skeleton is not enough to timely be transmitted on rubber by abutted surface, and then skeleton stress is big, with Vehicle body, damper connection cause Joint failure in loosening, and upper connection anti-fatigue ability is poor, and causes cushion performance poor, contracting Short service life.

Utility model content

Technical problem to be solved in the utility model is in view of the foregoing drawbacks, to provide car high strength safe damper Top connecting assembly, connection reliability is high, and cushion performance is good, and anti-fatigue ability is strong, long service life.

The utility model solve its technical problem the technical solution adopted is as follows:

Car high strength safe damper top connecting assembly, including yielding rubber, inner frame, outer skeleton, described is outer Plate body is embedded in after yielding rubber to bend downward to continue to extend to form to be embedded in along axial direction by yielding rubber top circumferential surface and be delayed on the inside of skeleton The interconnecting piece inside rubber is rushed, plate body extends to form the mounting portion for connecting vehicle body outward outward in outer skeleton outside, buffers rubber Jiao Zhouxinchu is equipped with axis hole, and the inner frame is embedded at axis hole, and the colloid of the yielding rubber between inner frame, outer skeleton is embedded Equipped with cricoid support ring, support ring bottom end is extended on yielding rubber bottom face.

Further, mounting portion is equipped with multiple connection bolts, and mounting portion is planar structure, and mounting portion is triangle.

Further, the upper and lower ends of inner frame extend respectively on the outside of the upper and lower end face of yielding rubber.

Further, the bottom face of yielding rubber is equipped with multiple convex blocks protruded to bottom, and convex block is on the outside of inner frame Circle-shaped uniform arrangement, the upper surface of rubber bumps are equipped with the cavity of inside, and inner frame top extends in cavity, cavity side walls Upper end is equipped with multiple coordinating blocks being uniformly distributed circumferentially, and the upper end of coordinating block is globoidal structure.

The beneficial effects of the utility model are: using the above scheme, the connection of outer skeleton, inner frame and yielding rubber is tight Close, connection is reliable, outer skeleton, inner frame stress load can timely be absorbed and buffer by yielding rubber, there is preferable buffering Performance, support ring strengthen the structural strength of yielding rubber, improve anti-fatigue ability, greatly extend service life.

Detailed description of the invention

Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will It becomes apparent.

Fig. 1 is a kind of vertical section structure schematic diagram of embodiment of the utility model.

Fig. 2 is a kind of top view of embodiment of the utility model.

Fig. 3 is a kind of bottom view of embodiment of the utility model.

Wherein: 1 is yielding rubber, and 11 be convex block, and 12 be coordinating block, and 2 be inner frame, and 3 be outer skeleton, and 4 be support ring.

Specific embodiment

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

Referring to Fig.1, car high strength safe damper top connecting assembly, including yielding rubber 1, inner frame 2, outer skeleton 3, the inside plate body of outer skeleton 3, which is embedded in after yielding rubber to bend downward by 1 top circumferential surface of yielding rubber, to be continued to extend shape along axial direction At the interconnecting piece 31 inside insertion yielding rubber, interconnecting piece 31 is cylindrical shape, is embedded in yielding rubber 1, inner end insertion buffering The inside of rubber, external horizontal extension outward form the mounting portion for connecting with vehicle body of the planar structure of triangle, peace Dress portion area is big, can effectively fix upper junction plate, meanwhile, the outer skeleton of plate makes its own with buffer capacity, dermoskeleton The stress load of frame is directly transmitted with interconnecting piece to yielding rubber, can timely buffer stress, outer skeleton is avoided to connect with vehicle body Place loosens, and axis hole is equipped at the axle center of yielding rubber 1, and the inner frame 2 of tubular is embedded at axis hole, and the upper surface of yielding rubber 1 is set There is the cavity of indent, the yielding rubber colloid top on cavity top is equipped with multiple coordinating blocks 11 being uniformly distributed circumferentially, cooperation The upper end of block 11 is globoidal structure, and the lower end surface of yielding rubber 1 is equipped with multiple downwardly projecting convex blocks being uniformly distributed circumferentially 12, convex block 11, coordinating block 12 form the position limiting structure of yielding rubber upper and lower end face, match with the corresponding position of car body or damper It closes, improves precision, the tightness of cooperation, avoid that opposite sliding occurs, avoid generating noise, between inner frame 2, outer skeleton 3 Yielding rubber 1 colloid in be embedded with cricoid support ring 4, the bottom end of support ring 4 extends to yielding rubber bottom face, support Ring 4 strengthens the structural strength of yielding rubber, improves the anti-fatigue ability of yielding rubber, and rigidity improves, and prolongs the service life, The top of inner frame 2 extends in cavity, and the bottom end of inner frame 2 extends to outside the bottom face of yielding rubber, improves yielding rubber Internal rigidity reinforces that yielding rubber enabling capabilities are reduced and shaken, improves the buffer capacity on axis.

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.
