[0003] Traditional engine hydraulic mounts primarily focus on shock absorption. However, with the continuous increase in engine power density, the heat generated increases significantly. Existing mounts are inadequate in heat dissipation. Excessive temperature can affect the performance of the hydraulic oil inside the mount, causing changes in its viscosity. This leads to unstable shock absorption and, in the long term, exposure to high temperatures accelerates the aging of internal rubber components and seals, shortening their service life. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-6 This utility model discloses a shock-resistant and highly efficient heat dissipation engine hydraulic suspension bracket, including a carrier frame 1 and a suspension bracket body 2 mounted on the carrier frame 1, and further including a heat dissipation reinforcement component 3, a shock absorption reinforcement component 4, a hydraulic oil tank component 5, an engine fixing component 6, and a bracket fixing component 7, wherein:

[0025] The supporting frame 1 has a sloping structure, and a lower rubber layer 11 is provided on the top surface of the lower slope, with a through hole 12 on the lower rubber layer 11.

[0026] Please refer to the appendix. Figure 3 The heat dissipation enhancement component 3 includes a heat dissipation channel 31, which is located on the suspension bracket body 2. The heat dissipation channel 31 has a serpentine structure. A heat dissipation fin 32 is welded to the outer side of the suspension bracket body 2. The heat dissipation fin 32 has a wave-shaped structure. The suspension bracket body 2 is provided with a support hole 21.

[0027] Please refer to the appendix. Figure 6The shock absorption and reinforcement component 4 includes partition cavities 41 that are equidistantly arranged in the suspension bracket body 2. The partition cavities 41 located at the highest and lowest points are connected to one end of the oil pipe 42, and the other end of the oil pipe 42 is connected to the oil reservoir 51. The partition cavities 41 are connected to each other through damping holes 43. Specifically, when the hydraulic oil passes through the damping holes 43 between the partition cavities 41, it can generate damping force, thereby enhancing the absorption and attenuation effect of vibration.

[0028] The through hole 12 is symmetrically provided with fixing holes 13 on both sides. The fixing holes 13 are locked to the suspension bracket body 2 by bolts. The through hole 12 abuts against the buffer rubber 52 at the bottom of the oil bag 51.

[0029] In this embodiment, the serpentine heat dissipation channel 31 below the partition cavity 54 can accelerate the heat exchange between the internal heat and the external air. At the same time, the wave-shaped structure of the heat sink 32 increases the heat dissipation area and air disturbance, improving the air convection heat transfer efficiency. When the vehicle is in motion, the high-speed airflow can quickly carry away the heat from the surface of the heat sink 32, cooling the suspension bracket and thus preventing the oil tank 51 from being affected by long-term high temperature, which would affect the performance of the hydraulic oil. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 2 , Figure 4 as well as Figure 5 The hydraulic oil tank assembly 5 includes an upper oil tank cavity 53 and a lower oil tank cavity 54. The upper oil tank cavity 53 is connected to the uppermost partition cavity 41 via an oil pipe 42, and the lower oil tank cavity 54 is connected to the lowermost partition cavity 41 via an oil pipe 42.

[0031] The oil pack 51 is fitted into the support hole 21, and an installation hole 55 is provided between the upper cavity 53 and the lower cavity 54 of the oil pack.

[0032] The engine mounting assembly 6 includes a mounting plate 61, a mounting rod 62 welded to one side of the mounting plate 61, the mounting rod 62 fitting into the mounting hole 55, and the oil reservoir 51 being locked to the mounting rod 62 by bolts.

[0033] The mounting plate 61 has symmetrical engine mounting holes 63 at both ends, and a positioning pin 64 is provided between the engine mounting holes 63. The bottom of the oil tank 51 is locked to the suspension bracket body 2 by screws. Specifically, the positioning pin 64 can accurately determine the installation position of the suspension bracket, ensure the correct posture of the engine on the vehicle, and at the same time assist the connecting bolts in bearing part of the shear force, improving the reliability and stability of the connection.

[0034] The bracket fixing assembly 7 includes a bracket side plate 71. One end of the bracket side plate 71 is welded to one side of the suspension bracket body 2, and the other end is provided with a locking arc groove 72. The locking arc groove 72 is fitted into the mounting bracket 73. The mounting bracket 73 is welded to the carrier frame 1. The locking of the support side plate 71 and the carrier frame 1 can reduce the vibration of the engine in the left and right direction and prevent the bolts locking the engine from loosening due to left and right swaying.

[0035] In this embodiment, when the engine vibrates during operation, the vibration is transmitted to the suspension bracket. The lower rubber layer 11 and the buffer rubber 52 buffer and filter the vibration. The vibration drives the fixed rod 62 to circulate and squeeze the upper chamber 53 and the lower chamber 54 of the oil reservoir, so that the hydraulic oil enters the partition chamber 41 through the oil pipe 42 and flows between the partition chambers 41 under the action of the squeezing force.

[0036] The working principle and usage process of this utility model are as follows: When fixing the suspension bracket on the carrier frame 1, the buffer rubber 52 at the bottom of the oil bag 51 in the suspension bracket body 2 is first fitted into the through hole 12 of the carrier frame 1 to initially position the suspension bracket body 2. Then, the locking arc groove 72 of the support side plate 71 is fitted into the mounting bracket 73 and locked with bolts. The suspension bracket body 2 is locked by bolts and fixing holes 13, thus completing the fixing and locking of the suspension bracket to the carrier frame 1.

[0037] When fixing the engine on the suspension bracket, first use the positioning pin 64 to engage with the engine for positioning, and then use bolts to lock the fixing plate 61 to the engine through the engine fixing hole 63 to complete the installation.

[0038] When the engine vibrates during operation, the vibration is transmitted to the suspension bracket. The lower rubber layer 11 and the buffer rubber 52 buffer and filter the vibration. The vibration drives the fixed rod 62 to circulate and squeeze the upper chamber 53 and the lower chamber 54 of the oil tank, so that the hydraulic oil enters the partition chamber 41 through the oil pipe 42 and flows between the partition chambers 41 under the action of the squeezing force. When the hydraulic oil passes through the damping hole 43 between the partition chambers 41, it generates damping force, which enhances the absorption and attenuation effect of vibration. It also enables the suspension bracket to adaptively adjust the damping characteristics under different vibration conditions, effectively suppressing the transmission of engine vibration.

[0039] When vibration energy is converted into heat energy through damping force, the temperature inside the oil bag 51 and the partition cavity 41 continues to rise and conducts heat to the suspension bracket body 2. The serpentine heat dissipation channel 31 below the partition cavity 54 can accelerate the heat exchange between the internal heat and the external air. At the same time, the wave-shaped structure of the heat sink 32 increases the heat dissipation area and air disturbance, improves the air convection heat transfer efficiency, thereby reducing the overall temperature of the suspension bracket.
