The specific embodiment
Below be specific embodiment of the present invention and combine accompanying drawing, technical scheme of the present invention is done further to describe, but the present invention is not limited to these embodiment.
Extremely shown in Figure 4 like Fig. 1; Originally one drag four front and back linkage brake pumps to comprise front brake caliper 1, rear brake caliper 2 and interlock pump 3; The pump 3 that wherein links links to each other with automobile foot rest, and interlock pump 3 passes through oil connector 4 and cross whelk bolt 5 to link to each other with rear brake caliper 2 with front brake caliper 1 respectively.
In interlock pump 3, offer the front brake plunger cavity 31 that laterally arranges and with rear brake plunger cavity 32 and in front brake plunger cavity 31 and rear brake plunger cavity 32 brake pump piston 7 and pull back spring 8 are installed all, wherein pull back spring 8 is positioned at chamber the inner.Leather cup 21 before brake pump piston 7 front ends are equipped with, there is back leather cup 22 brake pump piston 7 rear ends, can guarantee the leak tightness of interlock pump 3 in braking procedure like this.
Position of driver is in the front portion of vehicle, front brake pump position too layout in the front portion of vehicle.So the rear brake oil pipe is longer than the front brake oil pipe far away, and the oil pipe swell increment is directly proportional with tubing length, the required liquid measure of rear brake is greater than front brake, and the return amount of each caliper can not be in full accord simultaneously.Because of above-mentioned factor, under same actuating force situation, the preceding brake system hydraulic coupling that is produced of stopping necessarily produces hydraulic coupling greater than the rear brake brake system.Root a tree name application force and counteractive principle can be known, the front and back antagonistic force of braking systemic effect on stretcher also is different, and the front brake antagonistic force is necessarily greater than the rear brake antagonistic force, and stretcher can produce lateral deviation, so that feel is uncomfortable.Therefore in interlock pump 3, also offer the balance valve pocket 33 that is communicated with front brake plunger cavity 31 and rear brake plunger cavity 32; The vertical setting of axial line of the axial line of balance valve pocket 33 and the axial line and the rear brake plunger cavity 32 of front brake plunger cavity 31 wherein; Each chamber of convenient like this processing interlock pump 3 can also guarantee the Channel Group of braking liquid between each chamber simultaneously.Valve body piston 9 and retracing spring 10 are installed in balance valve pocket 33, and O-ring seals 18 is installed on the valve body piston 9, the O-ring seals 18 main connections that rise between blocking-up front brake plunger cavity 31 and the rear brake plunger cavity 32.Current like this braking system liquid pressure is during greater than rear brake brake system hydraulic coupling; Just promote valve body piston 9 and shift to rear brake plunger cavity 32; Compensation rear brake hydraulic coupling, under the effect of balance cock, braking system liquid equilibrium of pressure before and after guaranteeing; Realize the optimum condition of braking, improved braking effect effectively.Under same action of hydraulic force, the braking force equilibrium of stopping and produce in front and back, synchronously.Balance valve pocket 33 1 ends are fixed with sealing bolt 19, and the other end is sealedly connected with stop lamp switch 20.Balance valve pocket 33 is the chamber of the moving pump 3 of consistent communications and liaison, makes things convenient for processing and manufacturing like this.Sealing bolt 19 mainly plays the effect that prevents that braking liquid from leaking.
On interlock pump 3, the lubricating cup 6 that communicates with front brake plunger cavity 31 and rear brake plunger cavity 32 is installed; Two chambers about in lubricating cup 6, being provided with a dividing plate 61 and said dividing plate 61 lubricating cup 6 chambers being separated into, front brake plunger cavity 31 and rear brake plunger cavity 32 respectively on the fluid infusion hole 16 through separately and overflow weir 17 and the lubricating cup 6 corresponding about two chambers be communicated with.When dangerous situations such as front brake or rear brake oil piping system appearance leakage, one of them brake system is the ability normal operation still like this, and safety is good.
In front brake plunger cavity 31 and rear brake plunger cavity 32, block 15 is installed all; Automobile foot rest is connected between the pump 3 with interlock and is connected with bearing pin 11, shaft clevis 12 and piston mandril 13 in turn; Piston mandril 13 1 ends and shaft clevis 12 are connected, and the other end is plugged in the block 15.During car brakeing; The chaufeur foot-treadle promotes 7 reaches of brake pump piston through shaft clevis 12, piston mandril 13, when leather cup 21 is crossed overflow weir 17 before the brake pump piston 7; Before and after the oil circuit of stopping just formed a fully enclosed hydraulic efficiency pressure system; Along with brake pump piston 7 continues to move ahead, the pressure in the hydraulic efficiency pressure system is increasingly high, and passes rear brake caliper 2 generation braking forces forward through oil pipe.With rear brake plunger cavity 32 accent places back-up ring 14 is installed all at front brake plunger cavity 31, block 15 is limited in the chamber of interlock pump 3, thereby anti-stop block 15 spins off in chamber in motion process through back-up ring 14.
Specific embodiment described herein only is that spirit of the present invention is made casehistory.Person of ordinary skill in the field of the present invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
