The technical solution of the utility model is: the connecting device of a kind of pair of back axle car chassis balancing suspension system and propelling rod, comprise the outer oil seal collar, the locking ring washer, asbestos mat, rotary middle spindle, the cylinder that it is characterized in that the middle part protrusion of rotary middle spindle is provided with the lining supporting with rotary middle spindle, asbestos mat and by interior jacket layer, middle jacket layer, the combination that sheathcoat constitutes, be nested with lining on the cylinder that protrude at the middle part of rotary middle spindle, asbestos mat, lining, the asbestos mat lateral wall is nested with by interior jacket layer, middle jacket layer, the combination that sheathcoat constitutes, on the rotary middle spindle of the two ends of lining, be provided with asbestos mat, the locking ring washer, the outer oil seal collar, asbestos mat is between lining and locking ring washer, locking ring washer and rotary middle spindle are located with four point symmetry rivetings, and the outer oil seal collar pushes on the groove that is embedded on the rotary middle spindle of locking the ring washer outside.

Jacket layer, middle jacket layer in described, the mutual socket of sheathcoat is combined as a whole, and interior jacket layer, sheathcoat are rigid material, and middle jacket layer is a nonrigid material.

The madial wall of jacket layer is provided with annular boss in described, and the annular groove on annular boss and the lining is joined work.

Described lining constitutes supporting use by two and half linings, and the lateral wall of lining is provided with annular groove, and annular groove is located at the middle part of the lateral wall of lining.

Described lining is a nonrigid material.

Described rotary middle spindle is post shapes, the cylinder of rotary middle spindle middle part for protruding, be provided with the concave station rank at the cylinder two ends of protruding, the outside, concave station rank is a groove, the rotary middle spindle both ends are irregular cylinder, irregular cylinder radially is provided with two planes and through hole of symmetry, irregular cylinder and two planes and through hole with connect propelling rod and join work.

The beneficial effects of the utility model are: after nonrigid material and rigidity sheathcoat are joined work, joining work with propelling rod, make physical property couplings such as direct point of attachment specific heat, elasticity modulus, magnification ratio, increase than the prior art bonded area, stressed even, wear-resisting, antitorque, endurance, connection are firm etc., and performance is greatly improved, and the utility model can guarantee safety traffic especially on the road of heavy load, road shape complexity, and every technical index significantly is better than prior art.
