Description
Technical field
The present invention relates to a kind of automobile hanging formula isolation mounting, belong to technical field of automobile.
Background technique
Suspension type isolation mounting is the common structure part of automotive engineering field, and its Main Function connects top bearing material or dynamic exciting thing and bottom fixed bearing, and decay bearing material or dynamic exciting thing are passed to the vibration of fixed bearing.
Suspension type isolation mounting generally adopts rubber material as elastic element, functionally, requires to have support and vibration-damping function.For playing support function, require that elastic element has sufficiently high static stiffness, to ensure the stability of system, and in order to play vibration-damping function, require that elastic element has enough low dynamic rate, these two aspects requires conflicting, the method that traditional design often adopts compromise, compromises, and is difficult to reach best performance.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of automobile hanging formula isolation mounting.
Technological scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of automobile hanging formula isolation mounting, comprising: support plate, connecting plate, variation rigidity conical spring, rubber elastic element, described support plate comprises left support plate, right support plate; Described connecting plate comprises left connecting plate, right connecting plate; Described left support plate, right support plate are welded and fixed, and left support plate, right support plate bottom are fixed by socket in rubber elastic element; Left connecting plate, right connecting plate is fixed with respectively outside described rubber elastic element; Be provided with the variation rigidity conical spring of extended state obliquely upward between described left support plate and left connecting plate, between described right support plate and right connecting plate, be provided with the variation rigidity conical spring of extended state obliquely upward; Described left support plate, right support plate, left connecting plate, right connecting plate are provided with mounting hole.
The middle node square of described variation rigidity conical spring is greater than two ends joint square, and the spring filament diameter of variation rigidity conical spring is increased gradually by small end to large end.
Also comprise metal spacing plate, described metal spacing plate is fixed on the bottom of left connecting plate and right connecting plate.
Preferably, described rubber elastic element is provided with arc groove.
Beneficial effect: a kind of automobile hanging formula isolation mounting provided by the invention, adopt the structure that variation rigidity conical spring matches with rubber elastic element, when static state carries, only rubber elastic element plays supporting effect, during dynamic carrying, conical spring provides and rubber elastic element opposite effect power, the system that realizes high static support stiffness, low dynamic rate characteristic.Conical spring have employed middle node square is large, two ends pitch is little traitorous square structure and spring filament diameter progressively becomes large change spring filament diameter structure by small end to large end, realize the nonlinear variable-stiffness characteristic of height, namely carrying is dynamically fiercer, the amplitude that moves up and down is larger, and helical spring provides larger reverse elasticity active force.In addition, the spacing movable end of device adopts rubber package structure, when device plays dynamic state limit, can provide and relax contact, reduce vibration and noise.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of automobile hanging formula isolation mounting, comprising: support plate 1, connecting plate 2, variation rigidity conical spring 3, rubber elastic element 4, and described support plate 1 comprises left support plate 11, right support plate 12; Described connecting plate 2 comprises left connecting plate 21, right connecting plate 22; Described left support plate 11, right support plate 12 are welded and fixed, and left support plate 11, right support plate 12 bottom are fixed by socket in rubber elastic element 4; Left connecting plate 21, right connecting plate 22 is fixed with respectively outside described rubber elastic element 4; Be provided with the variation rigidity conical spring 3 of extended state obliquely upward between described left support plate 11 and left connecting plate 21, between described right support plate 12 and right connecting plate 22, be provided with the variation rigidity conical spring 3 of extended state obliquely upward; Described left support plate 11, right support plate 12, left connecting plate 21, right connecting plate 22 are provided with mounting hole 5.Described left connecting plate 21 is provided with metal spacing plate 6 with the bottom of right connecting plate 22.Described rubber elastic element is provided with arc groove.
As shown in Figure 5, Figure 6, the middle node square of described variation rigidity conical spring 3 is greater than two ends joint square, and the spring filament diameter of variation rigidity conical spring 3 is increased gradually by small end to large end.Conical spring itself has certain variation rigidity mechanical characteristic, in order to strengthen variation rigidity characteristic further, have employed the structure that spring filament diameter progressively strengthens from small end to large end, and two ends pitch is little, middle node is apart from large structural design, make conical coil spring have the variation rigidity characteristic of height, conical coil spring mechanical characteristic as shown in Figure 7.Thus making whole isolation mounting move up and down fiercer, motion amplitude is larger, and the reverse elasticity active force that conical spring plays is larger, and whole isolation mounting dynamic rate is less, is more conducive to the performance of damping property.
As shown in Figure 4, during use, the top of the bearing material on automobile with left support plate, right support plate is connected, more left connecting plate, right connecting plate are connected with fixed support on automobile; By the adjustment to bearing material gravity, when making isolation mounting be in static loaded state, conical spring is in horizontal free state, does not play elastic reaction, plays elastic carrier effect by rubber elastic element.When be in dynamically carry time, when namely bearing material drives support plate relative connecting plate to move up and down, conical spring plays elastic reaction, provides the elastic acting force contrary with rubber elastic element.Therefore, this device has high static load-bearing rigidity, low dynamic load-bearing rigidity, and compared with traditional isolation mounting, the system that both ensure that has very high static support stability, achieves again desirable dynamic Low rigidity damping property.When rubber elastic element drives downward deformation at support plate, bottom is provided with the effect that metal spacing plate can play protection, support.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
