Embodiment Construction

[0025] Such as Figure 1-4 As shown, a parallel semi-active multi-dimensional damping seat suspension for engineering vehicles includes a static platform 1, a damping branch chain 2, a damping spring 3, a dynamic platform 4, and a seat body 5.

[0026] The top surface of the platform 43 on the moving platform 4 is fixedly connected with the seat main body 5, and the bottom surface is fixedly connected with one end of the band chute support 42. The other end of the band chute support 42 is fixedly connected with the top surface of the lower platform 41 of the moving platform 4, and the band chute support 42 is an arc support. The bottom surface of the lower platform 41 is fixedly connected with one end of the damping spring 3 . All fixed connections can be fixed with bolts. The bracket 41 with chute is evenly distributed at 120° between the upper and lower platforms of the moving platform 4, and the damping spring 3 is evenly distributed at 120° between the moving and static ...

Abstract

The invention provides a parallel active multidimensional vibration absorbing seat suspension for an engineering vehicle. The parallel active multidimensional vibration absorbing seat suspension for the engineering vehicle comprises a movable platform, a fixed platform, three vibration absorbing branch chains uniformly distributed and connected between the movable platform and the fixed platform,and damping springs, wherein the movable platform is composed of an upper platform, a lower platform and three supports connecting the upper platform and the lower platform into a whole, the three supports are provided with sliding grooves, the upper platform is connected with a seat body, and the lower platform is connected with the fixed platform through the damping springs; the upper sphericalangle piece of every vibration absorbing branch chain is matched with the corresponding support with the sliding groove to form a spherical pair, the lower end of the vibration absorbing branch chainis movably connected to a rotating shaft movably connected inside a square slot of the fixed platform. The parallel active multidimensional vibration absorbing seat suspension for the engineering vehicle can reduce rotation on the X axis and the Y axis as well as vibration on the Z axis and accordingly improve the driving comfort level and safety of a driver. The parallel active multidimensional vibration absorbing seat suspension for the engineering vehicle is simple and compact in structure, low in cost, convenient to manufacture and assemble and capable of achieving multidimensional vibration absorption and outstanding damping effects.

Description

technical field [0001] The invention belongs to the field of engineering vehicle seats, in particular to a parallel semi-active multi-dimensional damping seat suspension for engineering vehicles. Background technique [0002] Construction vehicles drive and work on non-road surfaces for a long time, and strong vibrations will be generated during this process, which makes the drivers of construction vehicles suffer from low-frequency (2-5HZ) high-intensity vibrations for a long time, which can easily cause occupational diseases such as spinal distortion and stomach problems. Diseases seriously impair the physical and mental health of drivers, affect work efficiency, and are prone to accidents. Currently, due to cost and technical reasons, most engineering vehicle seats only consider vertical vibration reduction, often ignoring pitch and lateral vibration reduction, so that the vibration reduction effect is often unsatisfactory. The inclined vibration not only affects the dri...
