Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1, engine left suspension assembly is made up of left suspension A and left mounting bracket B two parts.
Left suspension A shown in composition graphs 1-Fig. 4 forms primarily of base 1, shell 2, primary elastomeric shock pad 3, left and right partiting polarization rubber pad 4.Base 1 is for being connected with vehicle frame, and shell 2 is for being connected with left mounting bracket B, and left mounting bracket B is then direct to be connected with driving engine.
Primary elastomeric shock pad 3 sulfuration is fixed between base 1 and shell 2, plays the effect connecting base 1 and shell 2.The two ends, left and right of base 1 upwards bend, and each bending part are set with the fixing left and right partiting polarization rubber pad 4 of a sulfuration, and totally two bending parts, are correspondingly provided with about two partiting polarization rubber pads 4.
