Diverter 100 can be transmitted the vibration come and obtain buffering decomposition by face, on the other hand can disperse to pass by the vibration of transmitting
It is delivered on the rack gear 121 and steering linkage 122 of connection component 10, enables to rack gear while the stress for avoiding transmitting is concentrated
121 and steering linkage 122 on the vibration that receives, generated so as to avoid the vibration of rack gear 121 and steering linkage 122
Abnormal sound, therefore protecting against shock washer 11 can be greatly improved connection component 10 by the setting of damping trough 112 and solve to turn to abnormal sound
Ability.
When it is implemented, the side of protecting against shock washer 11 can be positioned only at according to specific implementation environment damping trough 112, or
Damping trough 112 is arranged on the end face of the two sides of protecting against shock washer 11 but asymmetric setting.
Fig. 1-Fig. 4 is please referred to, the high summation of the slot of symmetrically arranged two damping troughs 112 is less than or equal to protecting against shock washer 11
Thickness 1/2.
What needs to be explained here is that the high summation of the slot of two symmetrically arranged damping troughs 112 is erosion control in the present embodiment
The 1/2 of the thickness of washer 11 is hit, can guarantee the overall structure performance of protecting against shock washer 11 while improving cushioning ability, keep away
Exempt from the protecting against shock washer 11 for using load-bearing to generate to damage.When it is implemented, symmetrically arranged according to specific implementation environment two
The high summation of the slot of damping trough 112 is 1/3,1/4 etc. of thickness of protecting against shock washer 11 other ratios.
Please refer to Fig. 1-Fig. 4,113 transition of edge chamfering of protecting against shock washer 11.
What needs to be explained here is that in the present embodiment, 113 transition of volume edge chamfering of protecting against shock washer 11 can make
Protecting against shock washer 11 can smoothly enter steering gear housing 30 when mobile with connection component 10, avoid the phenomenon that generating clamping stagnation.
In the present embodiment, the chamfering 113 of protecting against shock washer 11 is fillet.When it is implemented, anti-according to specific implementation environment
The chamfering 113 for impacting washer 11 can also be oblique angle etc..
Fig. 1-Fig. 4 is please referred to, protecting against shock washer 11 is made of PA66+GF30 material.
What needs to be explained here is that protecting against shock washer 11 is made of PA66+GF30 material in the present embodiment, material tool
There are good mechanical strength, rigidity, hardness and toughness, and there is excellent creep resistant, dimensional stability and wear-resisting etc.
