Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows.
It is explained in detail with reference to the structure of Fig. 1-4 pairs of Multifunctional brake hoof balls of the present utility model：It is a kind of new
Type Multifunctional brake hoof ball, including brake drum 1, brake-shoe 2 and friction plate 3, the quantity of the brake-shoe 2 is two, symmetrically
The inner side of brake drum 1 is arranged at, the lower end of the brake-shoe 2 is provided with turning end 4, and the turning end 4 is with being located at the inner surface of brake drum 1
