Embodiment Construction

[0025] like Figure 1-4 As shown, a parallel semi-active multi-dimensional vibration-damping seat suspension for engineering vehicles includes a static platform 1, a vibration-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. Band chute support 41 is 120 ° evenly distributed between the upper and lower platforms of the moving platform 4, and the damping spring 3 is 120 ° evenly distributed between the moving an...

Abstract

The invention provides a parallel semi-active multi-dimensional damping seat suspension for engineering vehicles, which includes a dynamic platform, a static platform, three vibration-damping branch chains uniformly connected between the dynamic platform and the static platform, and a damping spring; Among them, the moving platform is composed of upper and lower platforms and three brackets with chute connecting the upper and lower platforms. The upper platform is connected with the main body of the seat, the lower platform is connected with the static platform through damping springs, and the ball corner fittings at the upper end of the vibration-absorbing branch chain are connected with the seat body. The bracket with chute cooperates to form a spherical pair, and the lower end is movably connected to the rotating shaft in the square groove of the static platform. The seat suspension can reduce the vibration of the X-axis, Y-axis rotation, and Z-axis moving direction, and improve the driving comfort of the driver. sex and security. The vibration-damping seat of the invention has the advantages of simple and compact structure, low cost, convenient manufacturing and assembly, multi-dimensional vibration reduction and outstanding vibration-reduction effect.

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...
