Abstract

The invention relates to a hydraulic suspension stiffness adjustment system, stiffness adjustment method and automobile, and relates to the technical field of automobiles and is designed for solving the problem of poor comfort of the whole automobile caused by poor suspension vibration isolation effect. The hydraulic suspension stiffness adjustment system includes a controller, a supercharge oil circuit and a pressure relief oil circuit, wherein that supercharge oil circuit comprises a liquid storage tank, a hydraulic pump and a one-way supercharge valve, and the pressure relief oil circuit comprises a one-way pressure relief valve, a one-way pressure boost valve, a one-way pressure relief valve and a hydraulic mount are all connected with the controller, and the controller is also connected with an ECU, a TCU, a vibration frequency sensor and a space angle sensor. The stiffness adjusting method utilizes the hydraulic suspension stiffness adjusting system to adjust the stiffness of thehydraulic suspension. The vehicle includes the hydraulic suspension stiffness adjustment system described above. The invention provides a hydraulic suspension stiffness adjusting system, a stiffnessadjusting method and an automobile for isolating vibration between a power train and a vehicle body, thereby improving driving and riding comfort.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hydraulic mount stiffness adjustment system, a stiffness adjustment method and an automobile. Background technique [0002] During the driving process of a vehicle driven by a gasoline or diesel engine, due to the operation of the engine itself (including the operation of the transmission, drive shaft, wheel train, generator, air-conditioning compressor and other powertrain-related components driven by it), it will The car body brings different degrees of vibration. This vibration will be further transmitted to the seat, thereby greatly reducing the comfort of the ride. In order to alleviate the uncomfortable ride caused by engine vibration, generally, a suspension is provided between the engine and the vehicle body. [0003] The mount is a support and vibration isolation element located between the engine and the car body. It can effectively isolate the vibration and noi...
