Abstract
The utility model relates to a kind of brake device for car, a kind of improved braking automobile oil cylinder specifically, comprise cylinder body, have oil inlet hole on cylinder side wall, cylinder base is evenly equipped with at least two oil outlets, in cylinder body, there is baffle plate, baffle plate is divided at least two the first chambers by cylinder body, has an oil outlet and a piston in each first chamber, and piston is connected with piston rod, the piston rod the other end is connected in same dunnage, and dunnage is connected with connecting rod; Between described piston and cylinder body, have the second chamber, described oil inlet hole communicates with the second chamber, and there is gasket seal the contacting point of piston and cylinder body, baffle plate, has the second compensate opening on piston, and the second compensate opening is communicated with the first chamber with chamber.When driver's pin touches on the brake pedal, by connecting rod, promote piston and move, make the fluid that is entered the first chamber by oil inlet hole act on brake shoe realization braking from oil outlet, when there is leakage of oil in one of them, still fluid can be flowed to brake shoe, complete brake, guarantee traffic safety.
Description
Technical field
The utility model relates to a kind of brake device for car, specifically a kind of improved braking automobile oil cylinder.
Technical background
Current car brake pump parcel master cylinder has mobile piston in master cylinder, and master cylinder front end has an oil inlet hole, and there is an oil outlet rear end.When driver's pin touches on the brake pedal, by linkage mechanism, promote piston and move backward, the fluid that makes to enter master cylinder by oil inlet hole acts on brake shoe from oil outlet and realizes braking, in braking process, during oil outlet leakage of oil, cannot complete brake, easily has traffic accident.
Model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of improved braking automobile oil cylinder is provided, this oil cylinder has at least two oil outlets, when one of them oil outlet leakage of oil, other oil outlet still can flow to brake shoe by fluid, complete brake, guarantee traffic safety.
For solving the problems of the technologies described above, the utility model provides a kind of improved braking automobile oil cylinder, comprise cylinder body, have oil inlet hole on cylinder side wall, cylinder base is evenly equipped with at least two oil outlets, in cylinder body, there is baffle plate, baffle plate is divided at least two the first separate chambers by cylinder body, has an oil outlet and a piston in each first chamber, and piston is connected with piston rod, the piston rod the other end is connected in same dunnage, and dunnage is connected with connecting rod; The second chamber that has annular between described piston and cylinder body, described oil inlet hole communicates with the second chamber, there is gasket seal the contacting point of piston and cylinder body, baffle plate, on piston, have the second compensate opening, the second compensate opening is communicated with the second chamber with the first chamber, also have Returnning spring between piston and cylinder base.
When driver's pin touches on the brake pedal, by connecting rod, promoting piston moves, fluid in oil inlet hole enters the second chamber is entered the first chamber from the second compensate opening, and supply with to brake shoe by oil outlet, realize braking, in braking process, have one of them, two, even during three oil outlet leakage of oils, other oil outlet still can be delivered to brake shoe by fluid, complete braking, guarantee traffic safety; End of braking, driver's releasing of brake pedal, piston is returned to home position under the effect of Returnning spring.
As further improvement of the utility model, on described cylinder side wall, also have the first compensate opening, the first compensate opening communicates with the first chamber.When the fluid in the second chamber is not enough to meet braking needs, can utilizes the first compensate opening to supplement fluid to the second chamber, thereby complete braking.
Improved braking automobile oil cylinder of the present utility model has at least two independently chambers, strong indoor have oil outlet and piston, when wherein one group while there is oil leakage phenomenon, other oil outlet still can flow to brake shoe by fluid, complete brake, guarantee traffic safety.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model braking automobile oil cylinder.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, improved braking automobile oil cylinder, comprise cylinder body 101, on the sidewall of described cylinder body 101, have oil inlet hole 102 and the first compensate opening 104, cylinder body 101 bottoms are evenly equipped with two to four oil outlets 103, in cylinder body 101, there is baffle plate 105, baffle plate 105 is divided at least two the first separate chambers 106 by cylinder body, in each first chamber 106, there are an oil outlet 103 and a piston 201, each piston 201 is connected with independent piston rod 202, piston rod 202 the other ends are connected in same dunnage 203, and dunnage 203 is connected 301 with connecting rod.The second chamber 204 that has annular between described piston 201 and cylinder body 101, described oil inlet hole 102 and the first compensate opening 104 all communicate with the second chamber 204, piston 201 has pad 205 sealings with cylinder body 101 contacting points, piston 201 also has pad 205 sealings with baffle plate 105 contacting points, on piston 201, have the second compensate opening 206, the second compensate opening 206 is communicated with the second chamber 204 with the first chamber 106, the fluid in the second chamber 204 can flow in the first chamber 106 by the second compensate opening 206.Between piston 201 and cylinder body 101 bottoms, also has Returnning spring 207, for piston 201 is resetted.
When driver's pin touches on the brake pedal, by connecting rod 301, promoting piston 201 moves right, fluid in oil inlet hole 102 enters the second chamber 204 is entered the first chamber 106 from the second compensate opening 206, and supply with to brake shoe by oil outlet 103, realize braking, in braking process, have one of them, two, even during three oil outlet 103 leakage of oils, other oil outlet 103 still can be delivered to brake shoe by fluid, complete braking, guarantee traffic safety; End of braking, driver's releasing of brake pedal, piston 201 is returned to home position under the effect of Returnning spring 207.
Above embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design principle; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
