A hydraulic anti-lock brake wheel cylinder, comprising: a cylinder body (10), provided with a first cavity (11), and a first oil chamber interface (12), a second oil chamber interface (13) and an oil return interface (14); an end cover (70), arranged at an outer end of the first cavity (11); a first piston (30), arranged within the first cavity (11), a first spring (50) being provided between the first piston (30) and the end cover (70), a first oil chamber (33) being formed between the first piston (30) and the bottom of the first cavity (11), the first oil chamber (33) being connected to the first oil chamber interface (12), the first piston (30) being provided with a second cavity (34), a second piston (40) being arranged within the second cavity (34); a second spring (60), arranged between the second piston (40) and the bottom of the second cavity (34), a second oil chamber (43) being formed between the second piston (40) and the top of the second cavity (34); a core tube (20), arranged within the cylinder body (10), one end of the core tube (20) being connected to the second oil chamber (43), another end being connected to the second oil chamber interface (13), the oil return interface (14) being connected to the first oil chamber (33) when the first piston (30) moves outwards to a set position. A braking system provided with the brake wheel cylinder is capable of both braking and anti-locking. |
