Abstract
The invention discloses a brake main cylinder with double oil outlet connectors and a residual valve, which comprises a cylinder body; an oil chamber is arranged in the middle part of the cylinder body; a piston assembly is installed at the right end of the oil chamber; a residual valve spring and a return spring are installed at the left end of the piston assembly; a residual valve seat is installed at the left side of the return spring; a bottom surface sealing ring is installed at the left end of the residual valve seat; the cylinder body at the upper end of the piston assembly is provided with an oil inlet connector; an oil inlet valve core is installed in the oil inlet connector; and two oil outlet connectors are installed at the left end of the cylinder body. The brake main cylinder provided by the invention is provided with two oil outlet connectors, so that the main cylinder can output hydraulic pressures for two brakes at the same time. When the piston assembly or the valve has some problems and the hydraulic pressure of an oil outlet connector is insufficient, the other oil outlet connector can also work. Therefore, a protection measure is provided and the possibility of a risk is reduced.
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 residual valve with two delivery connections.
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 delivery connection are single delivery connection mostly, can only be to a break output hydraulic coupling; In case piston assembly or valve go wrong, under the hypodynamic situation of hydraulic pressure, single break is with regard to akinesia; Cause automobile brake malfunctioning, abnormally dangerous.Therefore imagination provides a kind of equipment to solve this problem.
Summary of the invention:
The object of the invention just provides a kind of brake master cylinder with residual valve with two delivery connections, solves brake master cylinder structure in the past, and its delivery connection is single delivery connection mostly; Can only be to a break output hydraulic coupling; In case piston assembly or valve go wrong, under the hypodynamic situation of hydraulic pressure, single break is with regard to akinesia; Cause automobile brake malfunctioning, breakneck technical problem.
The technological scheme that the present invention adopts is:
A kind of brake master cylinder with residual valve with two delivery connections comprises cylinder body: the cylinder body middle part has the grease chamber, and grease chamber's right-hand member is equipped with circlip for hole; The circlip for hole left end is equipped with thrust washer; The thrust washer left end is equipped with piston assembly, and the piston assembly right-hand member is set with apron outward, and the piston assembly left end is equipped with residual valve spring and return spring; The return spring left side is equipped with residual valve seat; Residual valve seat right-hand member middle part is equipped with the residual valve epithelium, on the residual valve epithelium sunk head rivet is installed, and residual valve seat left end is equipped with the bottom surface seal; The cylinder body of piston assembly upper end is provided with fuel inlet fitting, and the oil-feed spool is installed in the fuel inlet fitting, and oil-feed spool lower end is equipped with oiling valve apron and copper washer, oil-feed spool upper end suit oiling valve spring, and oiling valve spring upper end is equipped with check ring; The cylinder body left end has two delivery connections, and dust plug is installed in the delivery connection.
Said fuel inlet fitting and delivery connection all are connected to the grease chamber through oil duct.
Compared with prior art, beneficial effect of the present invention is:
The present invention can go wrong in piston assembly or valve respectively to two break output hydraulic couplings through two delivery connections are set; Under the not enough situation of certain delivery connection hydraulic coupling; Another can also be worked, and a kind of measures is provided, and has reduced the possibility that risk occurs.
