However, spring damping mainly converts the low-amplitude and high-frequency vibration of the motor into high-amplitude and low-frequency vibration.

[0030] Embodiment 4

[0031] See also Figure 1-Figure 5 As shown, the difference between this embodiment and the above embodiment is that the hydraulic shock absorbing assembly includes a shock absorbing seat 76 and a guide seat 724. The shock absorbing seat 76 is sealed and slidably mounted in the pressure chamber 715. A groove 719 is provided on the top surface of the shock absorbing seat 76.

When the motor housing 1 vibrates in the up and down directions, the motor housing 1 drives the guide seat 724 to vibrate up and down, thereby driving the side support wedge block 722, the side translation wedge block 723, the end support wedge block 728, the end translation wedge block 727 and the shock-absorbing seat 76 to vibrate up and down as a whole, so that the shock-absorbing seat 76 squeezes the coolant in the pressure chamber 715 to perform hydraulic shock absorption through the coolant in the pressure chamber 715; and when the motor housing 1 moves in the left and right directions When the motor housing 1 vibrates, the motor housing 1 drives the guide seat 724 to vibrate left and right. At this time, the guide seat 724 drives the shock absorber seat 76 to vibrate up and down through the sliding contact between the side support wedge block 722 and the side translation wedge block 723, so that the shock absorber seat 76 squeezes the coolant in the pressure chamber 715 to perform hydraulic shock absorption through the coolant in the pressure chamber 715; correspondingly, when the motor housing 1 vibrates in the front-to-back direction, the motor housing 1 drives the guide seat 724 to vibrate back and forth. At this time, the guide seat 724 drives the shock absorber seat 76 to vibrate up and down through the sliding contact between the end support wedge block 728 and the end translation wedge block 727, so that the shock absorber seat 76 squeezes the coolant in the pressure chamber 715 to perform hydraulic shock absorption through the coolant in the pressure chamber 715; Among them, through the cooperation of the shock-absorbing seat 76, the wedge block and the guide seat 724, the coolant in the pressure chamber 715 can provide hydraulic shock-absorbing support for the motor housing 1, so as to fully shock the motor housing 1 and further improve the stability of the motor.

[0032] Furthermore, the liquid inlet pipe 77 and the liquid outlet pipe 729 are both connected to an electromagnetic valve 78, which can adjust the inlet and outlet liquid flow rates, thereby adjusting the liquid pressure of the coolant in the pressure chamber 715, so that the coolant in the pressure chamber 715 can provide a suitable hydraulic support force.

[0033] Embodiment 5

[0034] See also Figure 3 , Figure 5-Figure 7 As shown, the difference between this embodiment and the above embodiment is that a flow guide cavity 725 is provided inside the flow guide seat 724, and the flow guide cavity 725 is connected to the corresponding pressure cavity 715 below through a movable connecting piece, and a liquid inlet hole 726 and a liquid outlet hole 730 connected to the flow guide cavity 725 on both sides are respectively provided at both ends of the cooling and heat dissipation flow channel 79; the movable connecting piece includes two universal ball joints 720 and a telescopic tube 721, and the two universal ball joints 720 are respectively installed on the bottom wall of the groove 719 and the top surface of the flow guide seat 724, and the lower universal ball joint 720 is connected to the pressure cavity 715, and the upper universal ball joint 720 is connected to the flow guide cavity 725, and the two universal ball joints 720 are connected through the telescopic tube 721; Among them, the pressure chamber 715 is connected to the guide chamber 725 in the guide seat 724 through two universal ball joints 720 and the telescopic tube 721, so that the coolant in the pressure chamber 715 can flow and be transported to the guide chamber 725, thereby realizing the flow and transportation of the coolant, and the shock absorbing seat 76 and the guide seat 724 are movably connected through the universal ball joint 720 and the telescopic tube 721, so that there is sufficient connection freedom between the shock absorbing seat 76 and the guide seat 724, so that the guide seat 724 and the shock absorbing seat 76 can realize a relative movement shock absorption process.

[0035] Embodiment 6

[0036] See also Figure 1-Figure 5 As shown, the difference between this embodiment and the above embodiment is that the hydraulic balance assembly includes a plurality of hydraulic balance pipes 710, which are fixedly installed on the outer side walls of the liquid distribution box 74 and the liquid collection box 75, respectively. One end of the hydraulic balance pipe 710 is connected to the pressure chamber 715, and the other end of the hydraulic balance pipe 710 is provided with an air inlet and outlet 718. A hydraulic plug 716 is installed in a sealing and sliding manner inside the hydraulic balance pipe 710, and a pressure balance spring 717 is installed in abutment with the outer end of the hydraulic plug 716. Among them, multiple hydraulic balance pipes 710 correspond to pairs of rubber shock-absorbing pads 4 respectively, and the air inlet and outlet 718 of the hydraulic balance pipe 710 are located on one side of the corresponding rubber shock-absorbing pad 4. At the same time, the hydraulic plug 716 maintains balance under the elastic force of the pressure balance spring 717 and the liquid pressure of the coolant in the pressure chamber 715. When the motor is damped by the coolant in the pressure chamber 715, the coolant in the pressure chamber 715 produces pressure changes with the up and down vibration of the shock-absorbing seat 76. When the liquid pressure of the coolant in the pressure chamber 715 decreases, the pressure balance spring 717 moves the hydraulic plug 716 toward the pressure chamber 715 to reduce the space in the pressure chamber 715 and increase the pressure. Correspondingly, when the liquid pressure of the coolant in the pressure chamber 715 increases, the coolant pushes the hydraulic plug 716 toward the air inlet and outlet 718 through the liquid pressure. The abutment movement increases the space in the pressure chamber 715 and reduces the pressure, so that the pressure in the pressure chamber 715 can be adjusted through the cooperation of the hydraulic balance pipe 710, the hydraulic plug 716 and the pressure balance spring 717 to prevent excessive hydraulic fluctuations in the pressure chamber 715 from affecting the normal delivery of the coolant; and when the hydraulic plug 716 moves toward the pressure chamber 715, a negative pressure is generated in the hydraulic balance pipe 710 to suck in the outside air, and when the hydraulic plug 716 moves toward the air inlet and outlet 718, the hydraulic plug 716 squeezes and blows the air in the hydraulic balance pipe 710 out from the air inlet and outlet 718, thereby blowing air and dissipating heat to the rubber shock absorber 4 through the air inlet and outlet 718, so as to reduce the temperature of the rubber shock absorber 4 and prevent the rubber shock absorber 4 from overheating and aging due to the internal molecular movement during shock absorption, which is beneficial to increasing the service life of the rubber shock absorber 4.
