The utility model is achieved through the following technical solutions:
A kind of Compound rubber suspension of front-end module, suspension top, suspension lower part including coaxial arrangement and outstanding Internal mounting hole is set, the cross section on the suspension top, which is that oval and edge is circumferentially interior, sets several equally distributed blind holes, Not only it can reduce the rigidity of suspension, but also X can be made different to the vibration isolation rate with Y-direction;The suspension top is mounted on front-end module When on frame, long axis direction is clearance fit, and short-axis direction is transition fit, existing positioning action, and can increase long axis side To vibration isolation rate;The suspension lower part outer profile be truncated cone, inside be filled with drag angle be greater than rubber plug-in unit; Mounting hole is through suspension top and suspension lower part inside the suspension, and inner wall is equipped with two column vertical setting of types dot matrix, is guaranteeing that fatigue is resistance to It can reduce suspension rigidity under long requirement;
This programme can obtain broader rigidity and damping in the case where shape size constancy compared to existing suspension Section, and preferably fatigue endurance characteristic and dynamic stiffness characteristic.
Further, the suspension top and suspension lower part are an integral structure.
Further, the hardness of the suspension lower part is bigger than the hardness for the plug-in unit being filled with inside it.
Further, the suspension mounting hole on the front-end module frame is oval, and the length of the suspension mounting hole Axis direction and short-axis direction are respectively parallel to the X-axis and Y-axis of vehicle coordinate system.
Further, when the front-end module is mounted on the front-end module frame, all Compound rubber suspensions In pressured state.
Further, mounting hole is ellipse inside the suspension, and the dot matrix is located at elliptical long axis direction.
Further, the dot matrix includes the salient point of several protrusions, is between the salient point and Compound rubber suspension Monolithic construction.
Further, the shape of the salient point is hemispherical.
Further, the difference of the radius of the major axis radius and salient point of mounting hole is equal to the suspension inside the suspension The minor axis radius of internal mounting hole.
The utility model compared with the existing technology, has the following advantages and effect:
1, by the ellipsoidal structure of design suspension top outer profile, X can be made different to the vibration isolation rate with Y-direction;
2, by the blind hole structure set in suspension, X, Y-direction rigidity are effectively reduced;
3, the vertical setting of types dot matrix in internal mounting hole is suspended by design, is guaranteeing wanting for fatigue endurance and original installation dimension It asks down, can reduce suspension rigidity
4, by the novel plug-in structure that sets in suspension, guarantee to suspend original outer dimension it is constant in the case where, can be with Broader rigidity and damping section are obtained, and preferably fatigue endurance characteristic and dynamic stiffness characteristic.

Specific embodiment
The utility model is more specifically described in detail combined with specific embodiments below, but the implementation of the utility model Mode is without being limited thereto.
As shown in Figure 1 to Figure 2, a kind of Compound rubber of front-end module suspends, in the suspension including coaxial arrangement Portion 1.1, suspension lower part 1.3 and the internal mounting hole 1.2 of suspension.As shown in Figs. 3-4, front-end module usually by radiator 2, Intercooler 3, condenser 4 form, and three generallys use rigidly connected mode and links together, and are suspended by Compound rubber 1 connect with front-end module frame 5.
As shown in Figure 1 to Figure 2, the cross section on the suspension top 1.1 be ellipse and edge circumferentially in set it is several Equally distributed blind hole 1.1.1 can effectively reduce suspension X to the rigidity with Y-direction, improve the vibration isolation rate of suspension.Described Suspension 1.3 outer profile of lower part is truncated cone, is formed by two kinds of Material claddings:It suspends the external using traditional of lower part 1.3 Rubber material uses the plug-in unit 1.3.1 of polyurethane material inside it.Since polyurethane material is to be not easy closely under normal conditions In conjunction with, and polyurethane has the characteristic being pressurized well, therefore need to suspend 1 to Compound rubber and carry out precompressed, guarantees to install Pressured state is at rear all Compound rubber suspensions 1.Relative to single rubber material, polyurethane material can be obtained more Big drag angle, due to its better damping characteristic, the rigidity that can design plug-in unit 1.3.1 is less than suspension lower part 1.3 Rigidity suspends 1 shape and fitted position not changing Compound rubber so that the rigidity of Compound rubber suspension 1 integrally reduces Under the premise of, play better effectiveness in vibration suppression.Pass through the different internal plug of change internal plug 1.3.1 size or replacement 1.3.1, different linearity range and rigidity can be obtained, different vibration isolation demands is met.Mounting hole 1.2 is inside the suspension Ellipse is equipped with vertical setting of types dot matrix 1.1.2 in mounting hole 1.2 inside the suspension through suspension top 1.1 and suspension lower part 1.3, The vertical setting of types dot matrix 1.1.2 is made of the salient point of several protrusions, and the shape of the salient point is hemispherical, the salient point with it is compound It is monolithic construction between rubber mounting 1, and the difference for suspending the major axis radius of internal mounting hole 1.2 and the radius of salient point is equal to institute State the minor axis radius for suspending internal mounting hole 1.2.This design can not modify the installation ruler of original radiator mounting portion 2.1 It is very little, and the rigidity of Compound rubber suspension 1 can be reduced under the requirement for guaranteeing fatigue endurance.
As described in figures 1 and 5,1.1 outer profile of suspension top is ellipse, is inserted into ellipse on front-end module frame 5 In circle suspension mounting hole 5.1, and the long axis direction of suspension mounting hole 5.1 and short-axis direction are respectively parallel to vehicle coordinate system X-axis and Y-axis.Under normal conditions, due to the vibratory output of front-end module Y-direction much larger than X to vibratory output, in the two directions The requirement for suspending 1 vibration isolation for Compound rubber is different.Due to front-end module X to vibration it is smaller, can be Compound rubber The X-direction of suspension 1 is set as short-axis direction, and with the suspension mounting hole 5.1 of front-end module frame 5 using the side of transition fit Formula plays the role of positioning meeting X under the premise of vibration isolation requirement;Since the vibration of front-end module Y-direction is larger, The Y-direction of Compound rubber suspension 1 is set as long axis direction, can increase the vibration isolation rate of suspension Y-direction, while Compound rubber It is logical that vibration can be effectively reduced in the mode that suspension mounting hole 5.1 in suspension 1 and front-end module frame 5 is gap-matched It crosses Compound rubber suspension 1 and is transmitted to vehicle body, cause interior vibration, improve the vibration isolation rate of suspension 1 to the greatest extent.
The utility model can be preferably realized as described above.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by described The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
