Abstract
The present invention relates to a kind of brake device for car, the specifically braking automobile oil cylinder of a kind of improvement, comprising cylinder body, cylinder side wall has oil supply hole, cylinder base is evenly equipped with at least two outlet-ports, baffle plate is had in cylinder body, cylinder body is divided at least two the first rooms, chamber by baffle plate, has an outlet-port and a piston in each first room, chamber, and piston is connected with piston rod, the piston rod the other end is connected in same back up pad, and back up pad is connected with connecting rod; Having the 2nd room, chamber between described piston and cylinder body, described oil supply hole communicates with the 2nd room, chamber, and there is gasket seal the contact position of piston and cylinder body, baffle plate, and piston has the 2nd compensate opening, and the 2nd compensate opening is by the first room, chamber and chamber. When driver's pin steps on brake pedal, promote piston to move by connecting rod, make the fluid entering the first room, chamber by oil supply hole act on brake-shoe realization braking from outlet-port, when there is leakage of oil in one of them, still can fluid be carried to brake shoe, complete brake, ensure driving safety.
Description
Technical field
The present invention relates to a kind of brake device for car, specifically the braking automobile oil cylinder of a kind of improvement.
Technical background
Current car brake pump parcel master cylinder, has the piston of movement in master cylinder, and there is an oil supply hole master cylinder front end, and there is an outlet-port rear end. When driver's pin steps on brake pedal, promote piston to move backward by linkage assembly, make the fluid entering master cylinder by oil supply hole act on brake-shoe from outlet-port and realize braking, when in braking process during outlet-port leakage of oil, brake being completed, easily have traffic accident.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, the braking automobile oil cylinder of a kind of improvement is provided, this oil cylinder has at least two outlet-ports, when one of them outlet-port leakage of oil, fluid still can be carried to brake shoe by other outlet-port, complete brake, ensure driving safety.
For solving the problems of the technologies described above, the present invention provides the braking automobile oil cylinder of a kind of improvement, comprising cylinder body, cylinder side wall has oil supply hole, cylinder base is evenly equipped with at least two outlet-ports, baffle plate is had in cylinder body, cylinder body is divided at least two the first separate rooms, chamber by baffle plate, has an outlet-port and a piston in each first room, chamber, and piston is connected with piston rod, the piston rod the other end is connected in same back up pad, and back up pad is connected with connecting rod; The 2nd room, chamber of annular is had between described piston and cylinder body, described oil supply hole communicates with the 2nd room, chamber, there is gasket seal the contact position of piston and cylinder body, baffle plate, piston has the 2nd compensate opening, 2nd compensate opening, by the 2nd room, chamber and the first chamber, also has return spring between piston and cylinder base.
When driver's pin steps on brake pedal, piston is promoted to move by connecting rod, the fluid entering the 2nd indoor, chamber by oil supply hole is made to enter the first room, chamber from the 2nd compensate opening, and supply to brake shoe by outlet-port, realize braking, when braking process has one of them, two, even three outlet-port leakage of oil time, fluid still can be delivered to brake-shoe by other outlet-port, complete braking, ensure driving safety; End of braking, driver's releasing of brake pedal, piston is returned to original position under the effect of return spring.
As a further improvement on the present invention, described cylinder side wall also having the first compensate opening, the first compensate opening communicates with the first room, chamber. When the fluid in the 2nd room, chamber is not enough to satisfied braking needs, the first compensate opening can be utilized to supplement fluid to the 2nd room, chamber, thus complete braking.
The braking automobile oil cylinder of the improvement of the present invention has at least two independent rooms, chamber, there are outlet-port and piston in strong indoor, when wherein one group oil leakage phenomenon occurs time, fluid still can be carried to brake shoe by other outlet-port, complete brake, ensure driving safety.
Accompanying drawing explanation
Fig. 1 is the sectional view of braking automobile oil cylinder of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, the braking automobile oil cylinder improved, comprise cylinder body 101, the sidewall of described cylinder body 101 has oil supply hole 102 and the first compensate opening 104, two to four outlet-ports 103 it are evenly equipped with bottom cylinder body 101, baffle plate 105 is had in cylinder body 101, cylinder body is divided at least two the first separate rooms, chamber 106 by baffle plate 105, each first room, chamber 106 has an outlet-port 103 and a piston 201, each piston 201 is connected with independent piston rod 202, piston rod 202 the other end is connected in same back up pad 203, and back up pad 203 is connected 301 with connecting rod. The 2nd room, chamber 204 of annular is had between described piston 201 and cylinder body 101, described oil supply hole 102 and the first compensate opening 104 all communicate with the 2nd room, chamber 204, piston 201 and cylinder body 101 contact position have pad 205 to seal, piston 201 and baffle plate 105 contact position also have pad 205 to seal, piston 201 has the 2nd compensate opening 206,2nd room, chamber 204 is connected by the 2nd compensate opening 206 with the first room, chamber 106, and the fluid in the 2nd room, chamber 204 can be flowed in the first room, chamber 106 by the 2nd compensate opening 206. Return spring 207 is also had, for being resetted by piston 201 between bottom piston 201 and cylinder body 101.
When driver's pin steps on brake pedal, promote piston 201 to moving right by connecting rod 301, making to enter the fluid in the 2nd room, chamber 204 by oil supply hole 102 enters the first room, chamber 106 from the 2nd compensate opening 206, and supply to brake shoe by outlet-port 103, realize braking, when braking process has one of them, two, even three outlet-port 103 leakage of oil time, fluid still can be delivered to brake-shoe by other outlet-port 103, complete braking, ensure driving safety; End of braking, driver's releasing of brake pedal, piston 201 is returned to original position under the effect of return spring 207.
Above embodiment is only the preferred embodiment of the present invention be described; not the scope of the present invention is limited; under the prerequisite not departing from inventive design principle; the various distortion that the technical scheme of the present invention is made by this area ordinary skill technician and improvement, in the protection domain that the claim book that all should fall into the present invention is determined.
