Abstract
The invention discloses a braking main cylinder provided with an oil cup assembly, an operating rod assembly and a center valve, which comprises a cylinder body. The right end of the cylinder body is provided with a protective cover. An oil chamber is arranged in the middle of the cylinder body, a piston assembly is installed at the right end of the oil chamber, and an operating rod is installed at the right end of the piston assembly. A valve core is installed at the left end of the piston assembly, a valve spring and a valve leather ring are sleeved on the valve core, a spring seat is installed at the left end of the valve core, a spring is installed at the left end of a spring seat, and the left end of the spring abuts against the inner wall of the cylinder body. An oil inlet is arranged on the cylinder body at the upper end of the valve core, and an oil cup assembly is arranged at the upper end of the oil inlet. An oil outlet connector is arranged on the side of the cylinder body, and a dustproof plug is installed outside the oil outlet connector. The oil inlet and the oil outlet connector are both connected onto an oil chamber through oil ducts. By adopting the structure that an oil cup is arranged on the cylinder body and an operating rod assembly is installed outside a piston, the braking main cylinder can effectively prevent dust and solid impurities from easily entering the cylinder body inside along with oil for braking and producing friction with the piston and a valve, and the whole service life of products is prolonged.
Description
Technical field:
The present invention relates to the auto parts and components field, relate in particular to a kind of brake master cylinder with centre valve with lubricating cup and operating stem assembly.
Background technique:
Brake master cylinder band vacuum booster assembly is that power source as braking system exists basically, and it is that brake pedal force with the driver is converted into hydraulic coupling, and has certain power-assisted effect, is divided into the total accepted way of doing sth of single piston assembly and double-piston usually; Brake master cylinder structure in the past, its filler opening is directly connected to Oil container, and dust and solid impurity are easy to piston and valve friction, cause damage along with braking gets into cylinder interior with oil.Therefore imagination provides a kind of equipment to solve this problem.
