Corrode and rub to protect car body component, according to particular/special requirement of the vehicle performance to subframe bush assembly 17, subframe bushing
Component 17 is made up of internal lining pipe 11 from the inside to the outside, rubber spring 13 and outer liner tube 12, and in the upper and lower side of rubber spring 13
Assembling upper holder block 14 and lower lock block 15, cause subframe bushing by the structure design of upper holder block 14, lower lock block 15, interior outer liner tube
The rigidity distribution of component 17 is more flexible, it is easier to meet vehicle performance demand, it is to avoid because the fatigue of subframe bush assembly 17 it is resistance to
Cracking slips the driving safety for causing long.A kind of subframe bush assembly of the present utility model, in terms of existing technologies,
This have the advantage that：Simple structure, can improve vehicle NVH and Vehicle handling, and stiffness equivalent is flexibly, reduces car load weight
Amount, so as to improve vehicle safety.
A kind of subframe bush assembly of the present utility model, refer to Fig. 3-7, on the basis of previously described technical scheme
On can also be：The left and right sides of 13 upper and lower end face of the rubber spring is equipped with perforate 16, and the upper holder block 14 is connected in institute
State in 13 upper surface perforate 16 of rubber spring, the lower lock block 15 is connected in 13 lower surface perforate 16 of the rubber spring, institute
State upper holder block 14 and the lower lock block 15 is fixed with the 16 inwall interference fit of perforate of 13 upper and lower end face of the rubber spring respectively
Connection.So, the left and right sides in 13 upper and lower end face of rubber spring offers perforate 16, and 14 interference fit of upper holder block is assemblied in
In the perforate 16, being assemblied in 13 lower surface perforate 16 of rubber spring for 15 interference fit of lower lock block is realized fixing, and adopts
With upper holder block 14 and lower lock block 15,16 interference fit of perforate with the upper and lower end face of rubber spring 13 respectively, to subframe bushing
Compression and supporting role are played in the radial direction of component 17 and axial direction, it is to avoid because the cracking slippage of 17 fatigue endurance of subframe bush assembly is drawn
The driving safety for rising.Further preferred version is：The upper holder block 14 and the lower lock block 15 include tabletting 20 and pressure
Seat 21, the wedge 21 is fixedly installed at 20 liang of side bottom positions of the tabletting, and the wedge 21 is connected in the rubber
In the perforate 16 of 13 upper and lower end face of main spring.So, upper holder block 14 is identical with the structure of lower lock block 15, by tabletting 20 and is fixed on
The wedge 21 of 20 bottom of the tabletting is constituted, by wedge 21 is connected in the perforate 16 of 13 upper and lower end face of rubber spring, and
And upper holder block 14 and lower lock block 15 with 13 interference fit of rubber spring, and then by upper holder block 14 and lower lock block 15 and rubber spring
13 are fixed, durable and will not also release, it is to avoid the resistance to rigidity failure radial and axial long afterwards of subframe bush assembly 17 and lead
Cause subframe bush assembly 17 to come off, security incident occurs, improve security reliability.Can also be：12 upper end of the outer liner tube
The flanging 18 outwards dug is provided with from top to bottom, 12 lower end of the outer liner tube is provided with the in-flanges for inwardly ploughing under from the bottom to top
19.So, 12 upper end of outer liner tube of subframe bush assembly 17 adopts flanging 18, lower end to adopt in-flanges 19, outer liner tube 12
Using inside and outside turnup structure, coordinate with upper lower lock block, the radial rigidity and beat of subframe bush assembly 17 can be effectively improved
Rigidity requirement, so as to improve the safety coefficient of car load.Further preferred version is：The inwall of the flanging 18 and the rubber
The outer wall of main 13 upper end of spring of glue offsets, and the inwall of the in-flanges 19 is offseted with the outer wall of 13 lower end of the rubber spring.So,
When subframe bush assembly 17 is deformed to a certain amount of, upper holder block 14 and 15 briquetting of lower lock block are contacted with interior flanging, change secondary car
The radial rigidity and beat rigidity requirement of the stiffness curve and subframe bush assembly 17 of frame bush assembly 17.It is further preferred
Scheme is：20 upper surface of the tabletting is provided with least one lightening hole 22.So, the upper surface in tabletting 20 arranges at least one
Lightening hole 22, can mitigate the weight of subframe bush assembly 17, reach lightweight demand.Further preferred version is：Institute
State lightening hole 22 to be evenly distributed on the upper surface of 20 left and right sides of the tabletting.So, lightening hole 22 is evenly distributed on pressure
The dynamic balance at the left and right two ends of tabletting 20 on the upper surface at the left and right two ends of piece 20, can be made, will not be counted because of one side lightening hole 22
Amount is more, causes overweight one side to kick the beam, causes weight imbalance, therefore, lightening hole 22 is uniformly distributed the active force for making tabletting 20
Balance, while also mitigating the weight of subframe bush assembly 17, reaches lightweight demand.
A kind of subframe bush assembly of the present utility model, refer to Fig. 3-7, on the basis of previously described technical scheme
On can also be：11 center of the internal lining pipe is provided with installing hole 23, and the installing hole 23 is to extend to bottom by top
Through hole.So, the inner hub location in internal lining pipe 11 arranges installing hole 23, can be completed to subframe by installing hole 23
Axle by installing hole 23, is passed through installing hole 23 by the assembling of bush assembly 17, using axle by subframe bush assembly 17 and vehicle body
It is assembled together.Can also be：11 longitudinal section shape of the internal lining pipe is swelling-waist shape.So, the longitudinal section of internal lining pipe 11
Swelling-waist shape is shaped to, the axial rigidity that can improve subframe bush assembly 17 is required, decay vibration transmission.Can be with
It is：The internal lining pipe 11 and/or the outer liner tube 12 are made up of aluminum alloy materials.So, internal lining pipe 11 and outer liner tube 12 are adopted
Aluminum alloy material, is greatly reduced can pts wt, so as to realize 17 light-weighted demand of subframe bush assembly.
It is above-mentioned only to this utility model in several specific embodiments be illustrated, but can not be used as of the present utility model
Protection domain, the equivalence changes or modification or equal proportion done by every design spirit according in this utility model amplify or contract
It is little etc., it is deemed to fall protection domain of the present utility model.
