The invention discloses a vehicle, a hydraulic mount and a flow channel assembly thereof, the flow channel assembly is provided with a first flow channel and a second flow channel which are not communicated with each other, and the flow channel assembly comprises a decoupling film; the first runner is used for communicating an upper cavity and a lower cavity of the hydraulic mount; the second flow channel can be communicated with the upper chamber and the lower chamber; the decoupling film has a free movement amount, can conduct or cut off a communication passage between the second flow channel and the upper chamber and between the second flow channel and the lower chamber when moving in a movement range of the decoupling film, and is configured to cut off the communication passage when being excited by a first amplitude and cut off the communication passage when being excited by a second amplitude. The decoupling film conducts the communication path, and the first amplitude is larger than the second amplitude. According to the flow channel assembly, the flow channel structure capable of being automatically opened and closed is additionally arranged, so that the hydraulic mount can have the performance of large amplitude, high damping, small amplitude and low rigidity.
