The invention belongs to the technical field of magneto-rheological brakes, and especially relates to a hydraulic magneto-rheological composite brake structure for a vehicle. The composite brake structure comprises shells, and the number of the shells is two. The positions of the two shells correspond to each other left and right; a bearing hole is formed in the middle of each shell; a bearing ismounted in each bearing hole; a main shaft is mounted between the bearings on the left side and the right side; a brake shell is mounted in the middle of the main shaft; and the brake shell is locatedbetween the shells on the left side and the right side, counter bores are formed in the outer edges of the shells, first threaded holes are formed in the outer edge of the brake shell, the counter bores correspond to the first threaded holes in position in a left-right mode, and a first bolt is placed in each counter bore. Current passes through a coil to enable the coil to generate magnetic force, and magneto-rheological fluid generates large resisting moment under the action of a strong magnetic field to hinder movement of a brake disc, so the main shaft is braked; and due to the arrangement of the brake blades, the brake disc bears large resistance in the braking process, and enough braking force is achieved.
本发明公开的属于磁流变制动器技术领域,具体为一种车用液压磁流变复合制动器结构,包括壳体,所述壳体数量为两个,两个所述的壳体位置左右对应,所述壳体中部开设有轴承孔,所述轴承孔中安装有轴承,左右两侧的所述轴承之间安装有主轴,所述主轴中部安装有制动壳,所述制动壳位于左右两侧的壳体之间,所述壳体外边缘开设有沉头孔,所述制动壳外边缘开设有第一螺纹孔,所述沉头孔与第一螺纹孔位置左右对应,所述沉头孔中放置有第一螺栓,电流通过线圈,使线圈产生磁力,在强磁场的作用下磁流变液产生较大的阻力矩,阻碍制动盘的运动,从而使主轴制动,通过制动叶片的设置,使制动盘制动时受到更大的阻力,从而具有足够的制动力。
