Specifically, referring to fig. 1 and 2, the rubber main spring 1 includes a main body 11, a supporting portion 12, and a connecting portion 13, the supporting portion 12 is disposed above the main body 11, the supporting portion 12 is of a rectangular frustum structure, and in a top-down direction, a cross-sectional area of a cross section of the supporting portion 12 perpendicular to a vertical direction is gradually increased, the connecting portion 13 is disposed above the supporting portion 12, and the connecting portion 13 is adapted to be connected with the bracket arm 30.

The bracket arm 30 is used for connecting a vehicle engine, the rubber main spring 1 is used for providing a force for supporting the vehicle engine, the supporting part 12 is used for supporting the connecting part 13, the main body part 11 is used for improving the structural strength and rigidity of the rubber main spring 1, the supporting part 12 is of a rectangular frustum structure, so that four wall surfaces of the peripheral wall of the supporting part 12 can provide an upward supporting force, and when the supporting part is of a herringbone structure, only two wall surfaces can provide an upward supporting force, therefore, the supporting part 12 is of a rectangular frustum structure, the supporting wall surface of the supporting part 12 is increased, the upward supporting force on the engine is improved, the rigidity of the hydraulic suspension 10 is improved, and the stability is improved. Meanwhile, the four wall surfaces of the peripheral wall of the supporting portion 12 can jointly resist the creep deformation of rubber, the durability of the rubber main spring 1 is improved, and the durability of the hydraulic mount 10 is improved, so that the hydraulic performance of the hydraulic mount 10 is stable.

Meanwhile, the rigidity of the hydraulic mount 10 in the first direction is improved by increasing the wall surfaces of the support portion 12 on two opposite sides in the first direction, without increasing the length of the support portion 12 in the first direction, so that the length of the hydraulic mount 10 in the first direction is reduced, and the hydraulic mount 10 is more convenient to install. In the present utility model, the first direction refers to the Y direction of the vehicle (the left-right direction of the vehicle body), and since the Y direction of the vehicle is limited in size, the hydraulic mount 10 of the present utility model can reduce the length of the rubber main spring 1 in the first direction compared to the herringbone rubber main spring under the same rigidity, thereby achieving the effect of reducing the Y direction of the vehicle.

And the wall surfaces of the support portion 12 on opposite sides in the first direction can restrict the displacement of the rubber main spring 1 in the first direction, thereby improving the durability of the rubber main spring 1 in the up-down direction, and thus improving the durability of the hydraulic mount 10.
