The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As illustrated in fig. 1 and 2, same as the prior art, hydraulic mount of the present utility model comprises a upper skeleton 1 and the lower skeleton 2 adaptive with it.As shown in Figure 3, upper skeleton 1 and lower skeleton 2 cooperate the back to form the chamber of a hollow.In this chamber, be equipped with the support portion 3 that is used to support the driving engine (not shown).This support portion 3 comprises screw rod 31 and these screw rod 31 bonded assembly aluminum components 32, and this aluminum component 32 vulcanizes in rubber bodies 33.In the bottom of hydraulic mount, form a liquid chamber that is used for ccontaining damping liquid by rubber bodies 33 and leather cup 6.
And unlike the prior art be, the hydraulic mount in the present embodiment also comprises a cushion layer 4 of being located on the upper skeleton 1, this cushion layer 4 coats end face and its side face of upper skeletons 1.Cushion layer 4 in the present embodiment adopts elastomeric material to make.Cushion layer 4 helps the location of whole hydraulic mount in car body, plays position-limiting action.Simultaneously, prevent vehicle because of in the driving process, the upper skeleton 1 of hydraulic mount bumps with other parts around it, and causes wearing and tearing or distortion, influences the service life of hydraulic mount.
As shown in Figure 3, upper skeleton 1 and lower skeleton 2 relative sides are respectively equipped with flanging 11 and flanging 12, and flanging 11 and flanging 12 radially have a certain width along upper skeleton 1.Simultaneously, the side face of rubber bodies 33 also is provided with the flange 331 of an annular.When upper skeleton 1 and lower skeleton 2 are placed in rubber bodies 33 wherein, in the middle of flanging 11 and flanging 12 are clamped in flange 331, and by link 53 riveted and fixed.
In addition, in order to make better fixedly upper skeleton 1 and lower skeleton 2, the inwall of this link 53 is formed with a boss 531.
Shown in Fig. 2 and 4, be provided with upper runner 71 and lower flow channel 72 in the liquid chamber of this hydraulic mount with helix inertia channel.This upper runner 71 is stacked with lower flow channel 72, and folder is established a decoupling zero dish 73 between them, thereby liquid chamber is divided into two-layer up and down.Like this, the energy of fluid flows loss not only loses from Local Damping in each cycle, but also derives from along the journey damping loss, reaches the purpose that increases damping.Simultaneously, decoupling zero dish 73 has been eliminated the dynamic stiffness rising that is brought by dynamic sclerosis, the phenomenon of high-frequency vibration isolation mis-behave.The hydraulic mount of this structure has that the low frequency dynamic stiffness is big, damping is strong, and the high frequency dynamic stiffness is little, good characteristics are imitated in sound insulation.
Again as shown in Figure 2, sulfuration has a leather cup skeleton 61 in leather cup 6 edges of this hydraulic mount, and this leather cup 6 is affixed by riveted joint mode and lower flow channel 72.Particularly, the upper surface of this leather cup skeleton and lower surface are all coated by the edge of this leather cup, thereby even if the element falling of riveted joint, the leather cup skeleton can not come off yet, and has improved the safety performance of hydraulic mount.The leather cup of this structure has reduced the number of components of hydraulic mount, has simplified erection procedure, makes that simultaneously the process that leather cup is installed is more easy.
Shown in Fig. 2 and 5, be used for hydraulic mount is fixed in the vehicle bottom, this hydraulic mount also comprises this bracket assembly 5.This bracket assembly 5 comprises a leg-of-mutton adapter plate 51, and the assembly hole adaptive with link 53 arranged in the middle of the leg-of-mutton adapter plate 51, and the hole wall of this assembly hole just is arranged in the bottom of the boss 531 of link 53.For the tetragonal adapter plate of available technology adopting, leg-of-mutton adapter plate 51 has better stability, further effectively prevent hydraulic mount and the fierce collision of the generation of the parts around it in the vehicle ' process, the service life of having improved hydraulic mount.In addition, in order to strengthen the intensity of adapter plate 51, all form a baffle plate of upwards turning up 52 at its three edges.
Though more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only are casehistorys, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
