So that section contacts approximate trapezoid structure, is contacted compared to traditional circle and triangle, have better reliability, be not easy to make
At contact surface damage, wherein outer lower portion limited block is then by active force and in the case of being deformed for longitudinal spacing block on the outside
Larger rigidity is further provided with it is combined into；Bushing rubber is caused integrally to produce when swing arm ontology generates complex working condition load
Change shape, to which then fitted bolt pad and installation bolt are that it further provides larger rigidity to miniature limited block, generally
Miniature limited block and outer lower portion limited block be bushing rubber by operating loading when the deformation corresponding matching that generates, to for
It further provides necessary rigidity.In compact SUV automobiles, the outside arch damping hole being arranged in bushing rubber is wide
Degree c is traditionally arranged to be 3 mm~5mm, and medial arch damping hole width b is traditionally arranged to be 2 mm~3mm, and such setting more accords with
The movement tendency for closing suspension is capable of providing higher rigidity in braking, and when steering can match better lateral rigidity, vulgar turn
Xiang Shi, the lateral force suffered by vehicle is smaller, and bushing rubber deflection is smaller, and under such state, bushing rubber not yet touches
Each limited block is capable of providing more smooth stiffness curve, and handling comfort is more preferably；When high speed steering, suffered by vehicle
Lateral force is larger, and bushing rubber deflection is larger, moves to the limited block where contact, to resist further deformation, provides
Larger rigidity enables the vehicle to realize fast steering and ensures the stability of vehicle body；The through-hole being equipped in bushing rubber,
Referred to as vertical circular damper apertures can effectively eliminate stress in swing arm ontology motion process, ensure that the work(of bushing rubber
It can property；
4）Bush of swing arm mounting bracket uses aluminium alloy extrusions, compared to traditional punching press sheet metal structural, has both had good
Vibration absorption ability, while because using proximate matter, process costs relatively low；The lightening hole opened up in bush of swing arm mounting bracket,
So that whole bush of swing arm mounting bracket has lightweight, absorbs the advantages that vibration and cost declining.
5）The installation bolt of setting can ensure have better safety under special operation condition, can ensure to connect
Component do not deviate from, so that vehicle is had better security performance.
