Out.
(3) beneficial effect
The utility model provides a kind of structure of assistant support of electric car rear-guard direct connection retarder, has following beneficial
Effect:
1, the utility model significantly reduces the deformation and vibration of retarder, improves electric car in the recessed not level line in hole in writing
The stationarity of road traveling, Shu Zaoxing.
2, the utility model aiding support ring and the aiding support circle form small―gap suture cooperation, and the cooperation of this small―gap suture can be with
Adjustment fit clearance as needed, until blind-mate, reaches different damping effects.
3, antidetonation slot is set on the utility model aiding support circle, elastic absorbing part is added in antidetonation slot, absorbs vibration
And impact.
4, setting retarder aiding support ring and guidance tape convenient for assembly on the outside of the utility model bearing gland, convenient for peace
Dress.
5, the utility model shares load, it is steady to help to improve retarder using vehicle rear-axle housing as shell a part
It is qualitative.
