Abstract

The invention relates to a nonlinear seat suspension with a tuning mechanism and a driving seat. The nonlinear seat suspension with the tuning mechanism comprises a suspension body, which is composedof an upper suspension, a vertical suspension and a lower chassis, inside the vertical suspension is provided with an elastic compressed unit connected with the upper suspension and the lower chassis,both sides of the vertical suspension are provided with cams, and the side surface of each cam, which is away from the vertical suspension, is in contact with a rolling mechanism; the nonlinear seatsuspension with the tuning mechanism also comprises the tuning mechanism for adjusting the preload of an elastic tensile unit; the tuning mechanism comprises horizontal sliding units, connecting unitsand adjusting units, which are all symmetrically arranged on both sides of the rolling mechanisms. The nonlinear seat suspension with the tuning mechanism can achieve the advantages of nonlinear contact, wide vibration isolation frequency band, low static rigidity, high dynamic rigidity and the like and is high in comfort level simple in design; besides, the tuning mechanism can achieve adjustment of the preload of the elastic tensile unit, ensure reliable and tight connection of the elastic tensile unit, give full play to the effects of the elastic tensile unit and prolong the service life of the elastic tensile unit.

Description

technical field [0001] The invention belongs to the field of vehicles, and more specifically relates to a non-linear seat suspension with a fine-tuning mechanism and a driver's seat. Background technique [0002] The driving chairs currently used in the market are especially those used in wheeled tractors and forklifts. Functions that are very important to the driver, such as driving functions and providing driving comfort, are not represented. [0003] The vibration damage suffered by the driver during work mainly comes from low-frequency vibrations. The stiffness of the existing driving seat suspension is relatively large, and the natural frequency of the seat suspension system becomes large, and the attenuation of the vibration caused by low frequencies is reduced. Rarely, it does not achieve the purpose of improving driver comfort. On the other hand, if the stiffness is small, the seat will cause a large displacement when the driver touches the seat. If the vehicle vib...
