With reference to Fig. 1-2, embodiments of the invention one comprise that a common double pipeline master brake cylinder (1) and two are from supercharging master cylinder (14,27), two of common double pipeline master brake cylinder oil outlets (7 wherein, 9) connect two respectively from supercharging master cylinder small oil tank (13,29) oil inlet (25,28), each comprises large tank (17) from supercharging master cylinder (is example with the right side), small oil tank (13), different diameter piston (15) and change-over valve core (23), above-mentioned change-over valve core is provided with pressure spring (20) and packing seal (21) near a side of large tank, two oil input channels (19,24) of change-over valve communicate with large tank and small oil tank respectively, and its opening lays respectively at the end position of end about different diameter piston (15).
With reference to Fig. 3, the embodiment of the invention two from the supercharging master cylinder, its structure is basic identical with embodiment one, just its change-over valve core is by two cylinders (30,32) be formed by connecting by a screw (31), pressure spring (20) is arranged in the side of spool near small oil tank.
The foregoing description is at glancing impact, and push rod promotes the middle piston (12) of common double pipeline master brake cylinder (1) and sets up oil pressure at oil pocket (10) and oil pocket (5), and pressure oil enters two respectively in supercharging master cylinder (14,27) small oil tank (13,29).Small oil tank (13) internal pressure oil promotes different diameter piston (15) and moves to right, in large tank (17), set up oil pressure, pressure oil enters change-over valve by oil duct (19), enters the braking fluid that brake cylinder provides big discharge capacity through oil duct (22), residual valve and brake piping.After brake clearance is eliminated, the right side is shifted in the effect that the interior oil pressure rising of small oil tank (13) makes change-over valve core (23) overcome pressure spring (20), close the output circuit (19) of large tank (17), open small oil tank (13), through oil input channel (24), change-over valve core (23), oil duct (22), residual valve and brake piping enter brake cylinder, and the braking fluid of elevated pressures is provided.Meanwhile the similar small oil tank of small oil tank (29) (13) is to another brake piping output braking fluid.
During brake off, common double pipeline master brake cylinder (1) piston (12,8) reach from supercharging master cylinder (14), different diameter piston (15), at pull back spring (11,6,18) get back to initial position under the effect, braking fluid flows back to from supercharging master cylinder (14) and common double pipeline master brake cylinder (1), braking fluid unnecessary in the brake piping flows back to reservoir compartment (3) by compensation orifice, compensation hydraulic fluid port (16) connects left chamber, reservoir compartment (3), and compensation hydraulic fluid port (26) connects right chamber, reservoir compartment (3), provides braking fluid to two brake pipings independently.
Supply the brake-line leak glancing impact of braking fluid from supercharging master cylinder (27) when the left side, the oil pocket (10) of common double pipeline master brake cylinder (1) is compressed to piston (12) to be stopped to relatively move with piston (8) dieback, push rod continues to promote piston (8) and moves, set up oil pressure at oil pocket (5), pressure oil enters in the small oil tank (13), realizes the braking of the intact brake piping in right side from supercharging master cylinder (14) by the right side.When the right side from supercharging master cylinder (14) supply the braking fluid brake-line leak the time, similar above-mentioned.
Its pressure spring of above-mentioned change-over valve (20) is arranged in small oil tank one side (as Fig. 3) glancing impact, starting stage small oil tank (13) internal pressure oil promotes different diameter piston (15) and moves to left, large tank (17) internal pressure oil is by oil duct (19) change-over valve and oil duct (22) output, oil pressure rising promotion spool (23) moves right in the large tank (17) after brake clearance is eliminated, close the output oil duct (19) of large tank (17), open oil input channel (24), small oil tank (13) internal pressure fluid is through oil duct (24) and oil duct (22) output.Higher braking oil pressure is provided.
