Moving plate side is suppressed, and caliper is internally provided with hydraulic fluid chamber structure, caliper both ends are provided with piston to brake disc direction,
Pistons end is connected with friction plate；The bracket is provided with ring groove to shaft shoulder face, and the first shell has been bolted, should
First shell is T shape circular ring structure；First shell passes through flanged joint to shaft shoulder direction on one side second housing, this second
Shell is T shape annulus slot structure；Cylinder roller bearing, and are mounted between first shell, second housing and shaft
Circular baffle plate has been bolted at both ends in one shell, second housing, which holds out against cylinder roller bearing in shaft
On the shaft shoulder；Hollow disc shape fixed disk, the fixed disk and shaft are fixedly connected with towards center of circle direction on the inside of the second housing
Between there are certain intervals；The shaft is connected with brake disc by flat key in fixed disk end positions, the brake disc and fixation
There are certain intervals between disk, second housing；The fixed disk outer edge is equipped with coil, and on the inside of coil and on the outside of brake disc
Between be provided with a circle magnetism-isolating loop.
Preferably, being filled with magnetorheological fluid in gap between the brake disc and second housing, fixed disk.
The beneficial effects of the utility model are: the structure is cooperated by the braking of double plate magnetorheological fluid and hydraulic brake caliper,
Good braking effect can be reached in lesser radial space.
