Problems solved by technology

[0003] Due to the good use effect and relatively low cost, hydraulic mounts have become the choice of many car companies. However, the damping characteristics of hydraulic mounts at this stage are generally single-frequency dynamic characteristics, which are difficult to adapt to various dynamic characteristics, and cannot be used according to road conditions. adjustments, thus limiting the usefulness of the hydromount

Embodiment 1

[0035] This embodiment relates to a hydraulic mount, such as figure 1 and combine Figure 2 to Figure 4 As shown in , its overall composition mainly includes a housing, a rubber main spring 3 , a connecting piece 3 , a leather cup 13 , a flow channel assembly and a control piece 14 .

[0036] Wherein, the shell is used as the structural basis of the entire hydraulic mount, not only for carrying other components, but also for forming the press fit of the hydraulic mount on the first external component. The first component is generally the body of the vehicle, and the second component connected to the connector 3 below corresponds to the powertrain mounted on the vehicle body. At the same time, as an exemplary structural form, the housing of this embodiment also includes an upper bracket 1 and a lower bracket 2 that are fastened up and down, and an end that is connected with the upper bracket 1 and the lower bracket 2 is formed with a valgus arrangement. The two flanges are cl...

Embodiment 2

[0051] This embodiment relates to a vehicle hydraulic mount system, such as Figure 6 As shown in , it includes a suspension unit 100 composed of the hydraulic mount in Embodiment 1, a drive unit 17 connected to the connection end of the control member 14 in the hydraulic mount, and a drive unit 17 for collecting the vibration excitation of the vehicle. The frequency acquisition unit 16, and the control unit 15 that receives the acquisition signal of the acquisition unit 16 to control the action of the drive unit 17 to output a linear driving force.

[0052] Wherein, when the control unit 15 controls the operation of the drive unit 17, the control member 14 receives the linear driving force and can reciprocate to open or block the second flow channel 12, so as to realize the adjustment of the performance of the hydraulic mount.

[0053] The acquisition unit 16 generally adopts an acceleration sensor installed on the vehicle, the control unit 15 can be integrated into the vehic...

Abstract

The invention provides a hydraulic suspension, a vehicle hydraulic suspension system and a control method thereof. The hydraulic suspension comprises a shell, a rubber main spring and a leather cup.The rubber main spring and the leather cup match the shell to form a liquid chamber. The suspension also comprises a flow channel assembly positioned in the liquid chamber and a connecting piece connected with the rubber main spring and exposed relative to the shell. A first flow channel communicating with the liquid chamber spaces on the upper side and the lower side and a second flow channel communicating and down and with the liquid chamber spaces on the upper side and the lower side are formed in the flow channel assembly, and a rigid control piece is fixedly connected to the position, corresponding to the second flow channel, of the middle of the leather cup. The hydraulic suspension can meet the requirements of various dynamic characteristics, and the use effect of the suspenion isimproved.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a hydraulic mount, and also relates to a vehicle hydraulic mount system using the hydraulic mount, and a control method for the system. Background technique [0002] Mount is a two-way vibration isolation element that connects and supports the powertrain and constrains and protects its movement trend. Currently, the mounts used on vehicles include rubber mounts, hydraulic mounts, semi-active mounts, and active mounts, etc. Various. The mount can fix and support the powertrain of the vehicle in use, bear the reciprocating inertial force and moment generated by the engine rotation and translational mass inside the powertrain, bear the dynamic force acting on the powertrain during the driving process of the vehicle, and isolate the Frame or body vibration caused by engine excitation, and isolating the transmission of body vibration to the powertrain due to road irregularities...
