Abstract
The utility model discloses a double-brake master cylinder assembly. The assembly comprises a cylinder body and a piston arranged in the cylinder body, wherein the piston further comprises a front piston and a rear piston; an oil inlet, an oil inlet through hole and an oil outlet which are matched with each piston are formed on the cylinder body; an oil inlet joint is set at the oil inlet; an oil inlet valve is arranged between the oil inlet and the oil inlet joint; a limit steel ball is arranged between the oil inlet valve and the oil inlet through hole; and a bulge matched with the limit steel ball is arranged at the front end of each piston. The arrangement of the bulges at the front ends of the pistons and the arrangement of the limit steel ball between the oil inlet valve and the oil inlet through hole enable the limit steel ball to stop the bulges of the pistons when the piston after operation resets to restrict the resetting route of the pistons and open the oil inlet valve simultaneously, so that brake fluid can flow back into a pipeline through the oil inlet through hole.
Description
Technical field
The utility model relates to the car hydraulic brake field, relates in particular to a kind of dual mixture induction system assembly that is used for car hydraulic brake.
Background technique
Traditional brake master cylinder by travelling forward of piston, is set up high pressure when work, pressure oil is exported from oil outlet; When the brake master cylinder inoperative, piston returns, and fluid is back to lubricating cup by compensate opening, and therefore, traditional brake master cylinder all need add compensate opening on cylinder body.But, offer compensate opening on cylinder body, its processing technology complexity, difficulty are big; And the fault rate height causes the waste of material serious.
The model utility content
The purpose of this utility model is in order to overcome technological deficiency recited above, a kind of dual mixture induction system assembly that does not need to process compensate opening to be provided.
In order to solve technical problem recited above, the utility model is taked following technological scheme:
A kind of dual mixture induction system assembly, include cylinder body, be arranged on the cylinder body inner carrier, this piston further includes secondary piston and back piston, on cylinder body, offer the filler opening, oil-feed through hole and the oil outlet that are complementary with each piston, be placed in the fuel inlet fitting of filler opening, between filler opening and fuel inlet fitting, be provided with oiling valve, be provided with spacing steel ball between oiling valve and oil-feed through hole, the front end of each piston is provided with the projection that matches with spacing steel ball.
The utility model is provided with projection by the front end at piston, and between oiling valve and oil-feed through hole, spacing steel ball is set, make and to return when resetting when the piston after the work, spacing steel ball blocks the projection of piston, in the limited piston return stroke, open oiling valve, make brake fluid flow back to pipeline by the oil-feed through hole.
The dual mixture induction system assembly structure that the utility model provides is avoided traditional double pipeline brake master cylinder structure, need not to process compensate opening, by improving piston structure, adopts spacing steel ball spacing, regulates the oiling valve gap and carries out the fluid compensation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. cylinder body, 2. position limit socket, 3. position limit socket pad, 4. back piston, 5. apron, 6. back piston spring, 8. back fuel inlet fitting, 9. oiling valve, 10. fuel inlet fittings, 15. secondary piston springs, 16. spring seats, 17. back delivery connections, 18. outlet valves, 91. oiling valve springs, 92. oil-feed valve seats, 93. oiling valve aprons before the delivery connections, 14. before the spacing steel ball, 11. projectioies, 12. secondary pistons, 13..
Embodiment
See also Fig. 1, as shown in the figure, the dual mixture induction system assembly includes cylinder body 1, is arranged on cylinder body 1 inner carrier, and this piston further includes secondary piston 12 and back piston 4; Piston is provided with apron 5; The tail end of back piston spring 6 butt secondary pistons 12, secondary piston spring 15 butts are arranged on the spring seat 16 of cylinder body front end; The rear end of cylinder body 1 is provided with position limit socket 2 and position limit socket pad 3; On cylinder body 1, offer the preceding filler opening that is complementary with secondary piston 12, oil hole and preceding oil outlet advance; On cylinder body 1, offer the back filler opening that is complementary with back piston, laggard oil hole and back oil outlet; Filler opening is mounted with back fuel inlet fitting 8 and oiling valve 9 in the back, and oil outlet is mounted with back delivery connection 17 and outlet valve 18 in the back; Fuel inlet fitting 14 and oiling valve 9 before preceding filler opening is mounted with, preceding oil outlet is opened in the front end port of cylinder body 1, and delivery connection 13 and outlet valve before preceding oil outlet is mounted with contact with the spring seat 16 that is arranged on the cylinder body front end at the outlet valve of preceding oil outlet; Be provided with spacing steel ball 10 between oiling valve 9 and oil-feed through hole, the front end of each piston is provided with the projection 11 that matches with spacing steel ball 10; Oiling valve 9 further includes oil-feed valve seat 92, oiling valve apron 93 and oiling valve spring 91.
When the dual mixture induction system assembly was worked, push rod promoted back piston and travels forward, and spacing steel ball is regulated oiling valve, makes the oiling valve apron seal fuel inlet fitting end face aperture, sets up high pressure; When the dual mixture induction system assembly was not worked, forward and backward piston returned, and spacing steel ball blocks the projection of piston, opened oiling valve in the limited piston stroke, made brake fluid flow back to pipeline by the oil-feed through hole.
Although the utility model has been done to describe in detail and quoted embodiment as proof, for those of ordinary skill in the art, obviously various schemes, modification and the change that can make according to above-mentioned explanation all should be included within the scope of claim.
