The beneficial effects of the utility model reside in that:

1. compared with a planar laminated plate rubber spring, the herringbone rubber spring can provide 10 times of Y-directional stiffness and 2-3 times of X-directional stiffness under the condition that the Z-directional stiffness (based on the coordinates of a whole vehicle) is kept unchanged. Therefore, the vertical comfort degree of the whole vehicle can be ensured, and the transverse stability and the driving stability are greatly improved.

2. The herringbone laminated structure can limit the laminated plates mutually when a large load and a large displacement occur, can effectively prevent the instability phenomenon, and can greatly improve the self reliability of the rubber spring compared with a plane laminated plate.
