The second brake block and first brake piece have been movably connected with, spring is equipped between second brake block and first brake piece,
The upper and lower ends of the housing front surface have been movably connected with first brake wheel cylinder and second by the second fastening screw and have stopped
The inner surface of vehicle wheel cylinder, the first brake wheel cylinder and the second wheel cylinder is respectively equipped with First piston bar and second piston bar,
And the end of First piston bar and second piston bar respectively with the second brake block and first brake piece hook joint.
Preferably, the inner surface of second brake block and first brake piece offers kidney slot, and kidney slot is straight
Diameter is more than two to three millimeters of the diameter of the first fastening screw.
Preferably, the quantity of the spring is four, and is arranged symmetrically.
Preferably, the housing is stainless steel material, and is embedded with round steel inside it.
Compared with prior art, the beneficial effects of the utility model are as follows：
The utility model has been movably connected with first in the upper and lower ends of housing front surface by the second fastening screw
Wheel cylinder and the second wheel cylinder, and pass through the effect of First piston bar and second piston bar, this hub can be made to stop in brake
In the process, have the advantages that uniform force, braking effect are stable and security performance is high, it is all only single to solve existing hub brake
Wheel cylinder controls brake block, leads to it during brake, and discontinuity, braking effect be unstable and poor safety performance
The problem of.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model left view structural representation.
In figure：1 housing, 2 first brake wheel cylinders, 3 springs, 4 second piston bars, 5 second brake blocks, 6 second wheel cylinder,
