The invention discloses a formula racing car with a porous variable-damping hydraulic mechanism. The formula racing car comprises a vehicle body main frame, wherein front independent suspension assemblies are arranged on the two sides of the front portion of the vehicle body main frame; a front vibration reduction suspension is arranged on the front portion of the vehicle body main frame the frontvibration reduction suspension comprises rotating blocks hinged to the two sides of the vehicle body main frame correspondingly; a first push rod is arranged between each rotating block and a front stand column on each front independent suspension assembly; a spring shock absorber is arranged between each rotating block and the vehicle body main frame; a connecting frame is connected between thetwo rotating blocks through a connecting rod; a variable-damping hydraulic mechanism is arranged between the vehicle body main frame and the connecting frame; one end of the variable-damping hydraulicmechanism is hinged to the vehicle body main frame; and the other end of the variable-damping hydraulic mechanism is hinged to the connecting frame. Hydraulic variable-damping vibration attenuation and multi-stage rigidity spring vibration attenuation are combined, different damping magnitudes can be generated under the impact action of different degrees, and the good vibration attenuation effectis achieved; and in addition, a very good inhibition effect is achieved on acceleration backward bending and sudden braking forward bending.

    本发明公开了一种具有多孔式变阻尼液压机构的方程式赛车,包括车体主架,车体主架前部两侧设有前独立悬架总成,所述车体主架的前部设有前减振悬架,前减振悬架包括分别铰接在车体主架两侧的转动块,转动块与前独立悬架总成上的前立柱之间设有第一推杆,每个转动块与车体主架之间均设有弹簧减振器,且两个转动块之间经连杆连接有连接架,所述车体主架与连接架之间设有变阻尼液压机构,变阻尼液压机构的一端与车体主架铰接,变阻尼液压机构的另一端与连接架铰接。本发明将液压变阻尼减振和多级刚度弹簧减振相结合,可在不同程度的冲击作用下,产生不同的阻尼大小,具有较好的减振效果;此外还对加速后仰和急刹车前俯起到了很好的抑制作用。
