Specific implementation mode
The present invention is more specifically described in detail with reference to specific embodiment, but embodiments of the present invention are unlimited
In this.
As shown in Figure 1 to Figure 2, the Compound rubber suspension of a kind of front-end module, including in the suspension of coaxial arrangement
Portion 1.1, suspension lower part 1.3 and suspension inside mounting hole 1.2.As shown in Figs. 3-4, front-end module usually by radiator 2,
Charge air cooler 3, condenser 4 form, and the rigidly connected mode of three's generally use links together, and is 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 1 need to be suspended to Compound rubber and carry out precompressed, ensure to install
It is in pressured state at rear all Compound rubber suspensions 1.Relative to single rubber material, polyurethane material can obtain 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 so that the rigidity of Compound rubber suspension 1 integrally reduces, and 1 shape and fitted position are suspended not changing Compound rubber
Under the premise of, play better effectiveness in vibration suppression.By changing internal plug 1.3.1 sizes or replacing different internal plugs
1.3.1, different linearity ranges 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 inside the suspension through suspension top 1.1 and suspension lower part 1.3 in mounting hole 1.2,
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 of suspension inside mounting hole 1.2.This design can not change 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 ensureing 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 that 1 vibration isolation is suspended 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 cooperation
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 can to efficiently reduce vibration for 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 present invention can be better realized as described above.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by the embodiment
Limitation, it is other it is any without departing from the spirit and principles of the present invention made by changes, modifications, substitutions, combinations, simplifications,
Equivalent substitute mode is should be, is included within the scope of the present invention.
