Stretch in outside the first mounting hole, lived by dust cover and protection hood guard, the lower end of dust cover passes through the flat collar hoop of double-round outside the ball pin of pin
Collar banding is tightly justified on the ball pin interlude of ball stud by individual pen in the first mounting hole outer upper end, the upper end of dust cover,
Shielding cover is located at outside ball stud and dust cover and is arranged on by hexagonal self-locking nut at the top of ball stud；
The shock absorbing bushing component includes small bushing general name and big rubber bushing；The big rubber bushing is set in small bushing
Outside assembly, big rubber bushing is fixed in the second mounting hole；Cavity is offered between the big rubber bushing and small bush Assembly,
Anti-icing fluid is filled with cavity.
Preferably, the first mounting hole central axis described in the utility model, ball stud central axis, dust cover centers axis
Line, protective cover central axis coincide.
Preferably, small bush Assembly central axis described in the utility model, big rubber bushing central axis, the second mounting hole
Central axis coincides.
Preferably, anti-icing fluid described in the utility model is ethylene glycol, propylene glycol mixture.
Preferably, ethylene glycol described in the utility model, the ratio of propane diols are 1:1.
Preferably, the flat collar of double-round described in the utility model is the flat collar of irony double-round.
Preferably, individual pen circle collar described in the utility model justifies collar for irony individual pen.
Compared to the prior art the utility model has the characteristics that and beneficial effect：
1st, the double set of small bush Assembly and big rubber bushing, considerably increases the damping effect of swing arm, improves car
Comfort and security.
2nd, cavity is offered in big rubber bushing, anti-icing fluid is filled with cavity, can effectively slow down the hardening of rubber, is extended
Service life, ensures the damping effect of swing arm.
