1. A hydraulic anti-lock brake wheel cylinder, comprising: a cylinder body, a core tube, a first piston, a second piston, a first spring, a second spring and an end cover; wherein,
the cylinder body is provided with a first cavity, a first oil chamber interface, a second oil chamber interface and an oil drainage interface, the end cover being disposed at an opening end of the first cavity; the first piston is disposed in the first cavity, and the first spring is disposed between the first piston and the end cover, a first oil chamber is formed between a bottom of the first piston and a bottom of the first cavity; the first oil chamber interface is communicated with the first oil chamber at one end thereof, and is connected to a foot brake valve at the other end; the amount of oil flowing from the first oil chamber interface into the first oil chamber is controlled by the foot brake valve; the first piston is provided with a second cavity in which the second piston is positioned, and a second oil chamber is formed between the second piston and a top of the second cavity, the second spring is disposed between a bottom of the second piston and a bottom of the second cavity; one end of the core tube is connected to a hand brake valve, and the other end thereof passes through the second oil chamber interface and is communicated with the second oil chamber, and the amount of oil flowing from the core tube into the second oil chamber is controlled by the hand brake valve; the oil drainage interface is communicated with the first oil chamber when the pressure of the first oil chamber increases and pushes the first piston to move outwardly to a set position. |
