Abstract
A brake assembly includes a cylinder body, a piston, an elastic piece, and a driving piece. The piston is mounted in an inner cavity of the cylinder body, so that the piston and the inner cavity of the cylinder body form an accommodating cavity. The driving piece and the elastic piece are disposed in the accommodating cavity, and the driving piece is connected to the piston through the elastic piece. The driving piece drives, through the elastic piece, the piston to move, so as to drive a brake to brake. When braking is canceled, the elastic piece can provide a pulling force for the piston, so that the piston is reset quickly.
Claims20
A brake assembly, comprising:
- a cylinder body comprising an inner cavity;
- a piston mounted in the inner cavity, wherein the piston and the inner cavity form an accommodating cavity;
