Abstract
A three-dimensional damping automobile seat suspension relates to an automobile seat. The three-dimensional damping seat is used for solving the problems that the existing seat mechanism of an engineering vehicle can only realize vertical damping, and is harmful to the health of a driver. A fixed support and a movable support are composed of three vertical steel angles respectively. Three groups of magnetorheological damper driving limbs are in parallel connection between the fixed support and the movable support to damp vibration and impact from various directions of the automobile seat. Due to a perpendicular arrangement, decoupling among degrees of freedom of a movable platform can be realized, and riding comfort of the vehicle is enhanced. In addition, the three groups of magnetorheological damper driving limbs are disposed in a closed space formed by the fixed support and the movable support, so that the three-dimensional damping seat is compact in structure, low in space occupation, and can meet strict requirement of space for seats on the automobile.
