Abstract
The invention discloses a dual-piston brake main cylinder with an oil outlet connector at the lateral side and an oil supplementing ring, which comprises a cylinder body; an oil chamber is installed in the middle part of the cylinder body; a rear piston assembly is installed at the right end of the oil chamber; a rear spring is installed at the left end of the rear piston assembly; a front piston assembly is installed at the left side of the rear spring; a locating pressing sheet is sleeved on the outer wall of the left end of the front piston assembly; a tightening spring is installed at the left end of the locating pressing sheet; a spring seat is installed at the left end of the tightening spring; a front spring is installed at the left end of the spring seat; limiting screws are installed on the cylinder body at the lower ends of the front piston assembly and the rear piston assembly; limiting screw gaskets are further installed between the limiting screws and the cylinder body; oil inlet connectors are arranged on the cylinder body corresponding to the upper ends of the front piston assembly and the rear piston assembly; and the lateral side of the cylinder body near each oil inlet connector is provided with an oil outlet connector. The oil outlet connector of the dual-piston brake main cylinder is arranged at the lateral side of the cylinder body, so that the oil returning efficiency is effectively improved, the unsmooth oil returning process is avoided and the service life of product is prolonged.
Description
Technical field:
The present invention relates to the auto parts and components field, relate in particular to the double-piston brake master cylinder with repairing ring of a kind of delivery connection at side.
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 single piston and double piston type usually; Brake master cylinder structure in the past, its delivery connection are to design in cylinder base, because the long-term hydraulic coupling that receives of using is bigger, receive the influence of liquid self gravitation simultaneously, the not smooth phenomenon of oil return often occurs.Therefore imagination provides a kind of equipment to solve this problem.
Summary of the invention:
The object of the invention just provides the double-piston brake master cylinder with repairing ring of a kind of delivery connection at side; Solve brake master cylinder structure in the past; Its delivery connection is that design is in cylinder base; Because the long-term hydraulic coupling that receives of using is bigger, receives the influence of liquid self gravitation simultaneously, the technical problem of the not smooth phenomenon of oil return often occurs.
The technological scheme that the present invention adopts is:
A kind of delivery connection comprises cylinder body at the double-piston brake master cylinder with repairing ring of side: the cylinder body middle part has the grease chamber, and grease chamber's right-hand member is equipped with the back piston assembly; Be set with the secondary apron in back on the back piston assembly right-hand member outer wall, back piston assembly left end is equipped with rear spring, and the rear spring left side is equipped with the secondary piston assembly; Be set with packing ring on the secondary piston assembly right-hand member outer wall; Be set with repairing ring, D shape seal ring and location compressing tablet on the secondary piston assembly left end outer wall, location compressing tablet left end is equipped with holddown spring, and the holddown spring left end is equipped with spring seat; The spring seat left end is equipped with front spring, and the front spring left end leans on cylinder body; Be separately installed with stop screw on the cylinder body of secondary piston assembly and back piston assembly lower end, the stop screw pad also is installed between stop screw and the cylinder body; The secondary piston assembly is provided with fuel inlet fitting respectively with corresponding cylinder body place, back piston assembly upper end, and fuel inlet fitting and cylinder body contacting point are equipped with the oil-feed seal ring, and fuel inlet fitting is set with dust cap outward; The other cylinder body side of each fuel inlet fitting all has delivery connection, and delivery connection is equipped with dust plug outward.
