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.
