Between support ring, be installed with fixed support on the outside of the top of the two side.
As a further improvement, the side wall has：Outwardly arc surface, and inwardly extend outside at openend
Top flange head；The sidepiece of the intermediate supports ring has gap, the top of the intermediate supports ring and institute with the arc surface
The inner segment for stating top flange head leans clamping contact, the bottom surface of the bottom of the intermediate supports ring and the intermediate supports bushing
Lean contact.
As a further improvement, the support bracket fastened outer rim has downward flange, the flange and the top
The outer section of collar head is leant clamping contact, and the top surface of the support bracket fastened bottom surface and the top flange head, which offsets, to be abutted against
Touch.
As a further improvement, it there also is provided centre between the intermediate supports bearing and the intermediate supports bushing
Support bushing support ring.
As a further improvement, the both ends of the intermediate supports bearing are respectively disposed with preceding dust ring and rear dust ring.
Intermediate supports rubber bushing is made Ω type section cyclic structures by the utility model, due to Ω type section cyclic structures
Before and after two side can Free Transform amount it is larger, under the premise of intermediate supports rubber bushing radial rigidity is ensured, greatly reduce
The axial rigidity of intermediate supports rubber bushing, buffering is fallen in vehicle traveling process starts caused by the elastic mounting of engine
Displacement caused by machine play and frame distortion, its axial impact force to middle spring bearing is eliminated, improves intermediate propeller shaft
The service life of intermediate supports bearing, simultaneously because simple in construction, cost is relatively low.
