Wherein, described elastomer bearing profile is column structure, and in the middle of column structure, little two ends are large, and one end of elastomer bearing press-in metal frame pedestal II through hole is shaped with the conical surface.
Wherein, described metal frame end cap is made up of end and insertion part, and described end lateral margin is shaped with inclined-plane, and one end, described insertion part is connected with end winding support, and the insertion part the other end inserts in elastomer bearing, and described end and insertion part are shaped with through hole.
Wherein, described metal frame pedestal II is made up of dunnage and support body, described support body is made up of large end and small end, and described small end and dunnage are connected to one and large end and dunnage are be arranged in parallel, and described through hole runs through dunnage, small end and large end.
The utility model compared with prior art structure is simple, cheap for manufacturing cost, easy to use, elastomeric material stretches compression strength is high, rebound elasticity is good, wear resistance, ageing resistance and damping, buffering performance significantly improve, and service life of aeroengine is significantly improved, and improve lorry driving safety simultaneously, reduce tare, reduce user's operation cost, reduce after-sales service workload to a great extent, improve lorry overall performance.

Embodiment
Below in conjunction with accompanying drawing 1-5, a kind of embodiment of the present utility model is described.
For the rear-suspending damping device of lorry motor, there is metal frame pedestal I 1 and metal frame pedestal II 2, described metal frame pedestal I 1 is in asymmetric U-shaped structure, described metal frame pedestal II 2 is made up of dunnage 13 and support body 14, described support body 14 is made up of large end 15 and small end 7, described small end 7 and dunnage 13 are connected to one and large end 15 are be arranged in parallel with dunnage 13, and described through hole 5 runs through dunnage 13, small end 7 and large end 15.Adaptive and the U-shaped inner chamber wall of metal frame pedestal II 23 sides and metal frame pedestal I 1 of the U-shaped cavity shape of three side structures of the dunnage 13 of described metal frame pedestal II 2 and metal frame pedestal I 1 is fixed with one, elastomer bearing 3 profile is column structure, and little two ends are large in the middle of column structure, one end that elastomer bearing 3 is pressed into metal frame pedestal II 2 through hole 5 is shaped with the conical surface 8.Elastomer bearing 3 is shaped with in the through hole 5 on one end press-in metal frame pedestal II 2 of the conical surface 8, metal frame end cap 4 is made up of end 9 and insertion part 10, described end 9 lateral margin is shaped with inclined-plane 11, one end, described insertion part 10 is fixedly connected with end 9, insertion part 10 the other end inserts in elastomer bearing 3, and described end 9 and insertion part 10 are shaped with through hole 12.The insertion part 10 of metal frame end cap 4 is inserted in the center hole 6 of elastomer bearing 3, and metal frame end cap 4 end 9 pushes against elastomer bearing 3 upper-end surface.
Metal frame pedestal I 1 select with automobile structural steel material simultaneously thickness reach 8mm its withstand voltage and wear-resisting property promoted, metal frame pedestal I 1 adopts
high-strength bolt is firmly connected with vehicle frame, and the place be connected with metal frame pedestal II 2 adopts the overall angle be applicable to of turning back to of steel plate, ensures metal skeleton base I 1 overall structure integrality and intensity.Metal frame pedestal I 1 adopts impact style to make, and compared to forging type, manufacturing efficiency and product cost all have superiority.
