[0039] Therefore, the rigidity of the engine suspension bracket 200 in the horizontal direction can be improved, and the displacement amount of the engine suspension bracket 200 in the horizontal direction, that is, the displacement amount of the engine in the horizontal direction, can be reduced, thereby improving the stability of the engine on the vehicle body.

[0041] According to the hydraulic mount 100 of the first aspect of the utility model, by setting the first damping cavity 22, the rigidity of the hydraulic mount 100 in the horizontal direction can be improved, when the engine mount support 200 in the mounting hole 21 is displaced in the first direction towards the first side wall 11, the damping liquid in the first damping cavity 22 can generate damping, thereby reducing the displacement amount of the engine mount support 200 in the first direction, and improving the stability of the engine on the vehicle body.
[0042] In some embodiments of the utility model, the first damping cavity 22 extends upwards to the middle of the mounting hole 21.

[0043] In some embodiments of the utility model, as shown in Figure 2 The second damping cavity 23 is arranged on the lower side of the mounting hole 21, and the first damping cavity 22 and the second damping cavity 23 are communicated.
[0044] During the operation of the vehicle, the damping liquid flows in the first damping cavity 22 and the second damping cavity 23, wherein, when the engine generates displacement in the up-down direction, the engine mount support 200 presses the main spring 20 downwards, the damping liquid in the second damping cavity 23 can generate damping force, thereby reducing the displacement amount of the engine mount support 200 downwards, and further improving the stability of the engine on the vehicle body.
[0045] In some embodiments of the utility model, as shown in Figure 2 And Figure 3 The bottom wall of the mounting groove 12 is formed with a through hole, the lower end of the second damping cavity 23 is open, the hydraulic mount 100 further comprises a cover plate 30, a lower flow channel piece 40, a decoupling film 50 and a sealing bowl 60, a plurality of up-down through flow channel holes 31 are formed on the cover plate 30, for example, two, three or four flow channel holes 31 can be formed on the cover plate 30, an up-down through hydraulic flow channel 41 is formed on the lower flow channel piece 40, the cover plate 30 is connected between the lower end of the framework 10 and the upper end of the lower flow channel piece 40, the main spring 20 is connected with the cover plate 30 through the through hole, the second damping cavity 23 is communicated with the hydraulic flow channel 41 through the flow channel hole 31, the decoupling film 50 is arranged in the hydraulic flow channel 41, and the sealing bowl 60 is capped at the lower end of the hydraulic flow channel 41.
[0046] During the operation of the hydraulic suspension 100, the main spring 20 is deformed under the extrusion of the engine suspension bracket 200, so that the damping liquid flows in the first damping chamber 22, the second damping chamber 23 and the hydraulic flow channel 41, wherein the damping liquid flows between the second damping chamber 23 and the hydraulic flow channel 41 through the flow channel holes 31, the plurality of flow channel holes 31 can make the damping liquid in the second damping chamber 23 more evenly distributed, so that the main spring 20 can make the force acting on the engine more evenly distributed, and the stability of the engine on the vehicle body is further improved.
[0047] The damping liquid in the first damping chamber 22 can generate damping force in the first direction, the damping liquid in the second damping chamber 23 can generate damping force in the up-down direction, and the damping liquid flowing in the hydraulic flow channel 41 passes through the decoupling film 50, the decoupling film 50 can reduce the resonance frequency of the hydraulic suspension 100, so as to further improve the stability of the engine on the vehicle body, and the sealing bowl 60 can seal the lower end of the hydraulic flow channel 41, when the components in the hydraulic flow channel 41 need to be maintained or the damping liquid needs to be replaced, the sealing bowl 60 can be opened, so as to facilitate the maintenance of the hydraulic suspension 100.

[0049] In some embodiments of the present application, as shown in Figure 1 and Figure 2 the first side wall 11 upwardly exceeds the lowermost end of the mounting hole 21.
[0050] Therefore, in the first direction, the first side wall 11 can be opposite to the part of the engine suspension bracket 200 in the mounting hole 21, when the engine suspension bracket 200 in the mounting hole 21 is displaced in the first direction towards the first side wall 11, the first side wall 11 and the engine suspension bracket 200 can extrude the damping liquid on both sides of the first damping chamber 22, so as to improve the damping force generated by the damping liquid in the first damping chamber 22, and further improve the stability of the engine on the vehicle body.
[0051] In some embodiments of the present application, the first side wall 11 extends to the middle part of the mounting hole 21 upwardly. Therefore, when the engine suspension bracket 200 in the mounting hole 21 is displaced in the first direction towards the first side wall 11, the first side wall 11 can have sufficient acting area on the main spring 20, so that the extrusion area of the damping liquid in the first damping chamber 22 is larger, and the stability of the engine on the vehicle body is further improved.
[0052] In some embodiments of the present application, as shown in Figure 3 the mounting groove 12 penetrates the framework 10 in the second direction.
[0053] Therefore, on the one hand, the two side walls of the mounting groove 12 in the first direction limit the main spring 20, which can meet the limiting needs of the hydraulic suspension 100 to the engine, on the other hand, the main spring 20 is less blocked when being assembled to the framework 10 during the assembly of the hydraulic suspension 100, which can reduce the assembly difficulty of the hydraulic suspension 100, in addition, the structure of the framework 10 can be simplified, and the production cost of the hydraulic suspension 100 can be reduced.

[0055] As can be understood by those skilled in the art, on the lower side of the main spring 20, the main spring 20 needs higher limiting degree, the second section 112 located on the lower side has a larger size in the second direction, and the second section 112 can provide better limiting to the main spring 20, which can more easily meet the limiting needs of the framework 10 to the main spring 20. On the upper side of the main spring 20, in order to ensure the absorption effect of the main spring 20 to the vibration on the engine suspension bracket 200, the first section 111 needs less blocking to the main spring 20, so that the upper side of the main spring 20 has a larger deformation angle, thereby making the main spring 20 better absorb the vibration on the engine suspension bracket 200.
[0056] In some embodiments of the utility model, the main spring 20 is a rubber material piece. The rubber material piece has good elastic performance, which can more easily make the damping effect of the main spring 20 meet the use needs, and the chemical properties of the rubber material piece are stable, which can improve the service life of the hydraulic suspension 100.
