Abstract
The utility model relates to an antioverbraking device for a vehicle brake, which comprises an upper and a lower shell bodies (1, 2) which are connected in the screwed connection mode. Hollow cavities are arranged in the shell bodies, and the hollow cavities of the shell bodies are provided with exit openings (3) which are connected with a hydraulic braking pipe. The interior part of each shell body is provided with a synchronous pulse reactor which is an air chamber with a glue container. The utility model provides an antioverbraking brake device of a mechanical vehicle and the antioverbraking device for a vehicle brake, which has the advantages of simple structure, low cost, good antioverbraking brake effect, and more convenient installation.
Description
The utility model relates to a kind of braking automobile anti-lock device, especially mechanical type braking automobile anti-lock device.
During automobile emergency brake, brake strap/brake shoe and wheel hub/video disc forms the friction of holding tightly, but general four wheels are held tightly simultaneously, and four present ground-surface friction of wheel are also also incomplete same, at this moment just easy (almost inevitable) produces direction out of control, the defective steering stabilizer sideslip, cause the generation of grave accident when especially vehicle is too fast easily, desirable brake modes (ABS) should be brake strap/brake shoe and wheel hub/the video disc locking in an instant, brake strap/brake shoe and wheel hub/video disc loosen slightly, stop again, loosen again, continuous repeatedly, guarantee like this can act on brake many times in each second, the continuity that makes vehicle produce " locking-rotation-locking-rotation " is moved, thereby the braking force one that acts on the vehicle remains on maximum always, wheel is unlikely to again to skid, and can make the vehicle can be effective, safety, steadily stop.
Existing ABS is the electronic type device, it utilizes Hall element to detect the commentaries on classics and the non-commentaries on classics state of vehicle, the brake solution pressure of modulated pressure brake cylinder, thereby reach the purpose of control brake degree of tightness, but existing ABS can only produce 8-18 pulsation of per second, and stopping distance can prolong more than 5%, and because complex structure, manufacturing cost is higher, and it is higher to install cost additional on existing car.
The purpose of this utility model is: provide a kind of braking automobile anti-lock anti-brake holding car device, especially mechanical type automobile anti-brake holding car device, provide a kind of simple in structure, cost is low, anti-brake holding better effects if, and automobile easy for installation is prevented brake holding car device.
The purpose of this utility model is achieved in that a kind of braking automobile anti-lock device, comprise the upper and lower casing that is threaded, in housing, be provided with cavity, housing is provided with two and picks out the hole, the housing cavity connects the hydraulic braking pipe by this hole, be provided with a synchronizing pulse reactor in the housing cavity, the synchronizing pulse reactor is glue courage chamber.
Principle of work of the present utility model is: when actual brake, brake strap/brake shoe and wheel hub/video disc forms friction device, because heat and other size factor, wheel hub/video disc produces slight and crooked and loses circle, and yet there are a lot of rough positions in the metal surface, protruding the position on glancing impact shoe plate/pad and the wheel hub/video disc forms when rubbing, in brake pipe, brake-pressure rises, when forming friction with recessed position, brake-pressure descends rapidly again, the gaseous tension that is dashed in advance in the glancing impact sebific duct has very fast frequency response to hydraulic pressure, and when stepping on brake pedal, elastic rubber tube depends on a Vibration Parameter at every turn, or expand or contraction (also relevant in the speed of a motor vehicle certainly), also with vehicle condition, particularly relevant with the distortion situation of wheel hub/video disc.When there was not idio-morphosis in wheel hub/video disc, the speed of a motor vehicle was for per hour 50 kilometers the time, and energy storage will make in the brake pipe lifting of hydraulic pressure per second 60-80 time, and the speed of a motor vehicle is for per hour 100 kilometers the time, and energy storage will make the interior hydraulic pressure per second lifting of brake pipe 120-140 time.When losing circle, goes up when protruding the position friction brake strap/pad and wheel hub/video disc, high hydraulic pressure makes energy storage obtain elastic energy, when brake strap/pad and wheel hub/video disc loses the friction of circle fovea superior position, lower hydraulic pressure is pressed the energy storage bleeding of brakes, thereby reach the purpose that brake fluid pressure is constantly divided equally, make the bigger braking force of generation between brake strap/pad and the wheel hub/video disc.
Characteristics of the present utility model are: this device is an automatically regulating formula anti-lock device, can be adapted to various hydraulic braked vehicles uses, braking ratio can reach more than 90%, shortened stopping distance, glancing impact can turn to, the control vehicle travel direction, make vehicle effectively, safety, pulsation-free stops, and increased the safety of glancing impact greatly.After the utility model used, when automobile during with 50-80 kilometer/hour sudden stop, its effect is tangible: originally sideslip 500-1100mm, wheel were understood locking, and present sideslip is all less than 100mm, and wheel is not substantially by locking.The utility model can independently be installed, and does not influence the work of master cylinder, and links together with master cylinder is organic, installs easily, has both supplied supportingly, conveniently is used to reequip existing vehicle again.Its price is low, and is easy to manufacture, can also prolong the life-span of motor tire.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model structural representation
The braking automobile anti-lock device, as shown in the figure, the left side and the right are respectively upper and lower casing 1,2, and the two links together by screw thread 4.In housing, be provided with cavity 10, housing is provided with and picks out hole 3, be connected with cavity and be connected with the hole by connection pipe, draw one among the figure, another is in the opposite or the side of housing, the hole connects hydraulic total pump and brake pipe respectively by connection pipe, is provided with a synchronizing pulse reactor in the housing, and the synchronizing pulse reactor is glue courage chamber.Because connection pipe is communicated with glue courage chamber with brake pipe inside brake liquid, within glue courage chamber was surrounded by last lower house connecting thread, glue courage chamber 5 was made by gassiness rubber or Polyurethane container, fitness for purpose oil resistant and heat-resisting material.Be full of the gas (as nitrogen, argon gas, carbon dioxide) or the air of inert in the air chamber, glue courage chamber is a column, and its volume is 2-6ml, is 3.2ml in the present embodiment.In the present embodiment, an end of glue courage chamber can be and the housing closed contact, also can be between this end and housing 6 be provided with the space, the other end 7 of glue courage chamber is connected with cavity, and contact with braking liquid, but housing is provided with sealing lip 8, with this side seal of glue courage chamber.
The end of upper shell is provided with a sealing screw 9, and the effect of this screw is: after remoulded car installs this device, unclamp screw earlier and deflate, and then tighten.But need not this screw when car load is supporting.
General two of the utility model is a cover, control four wheels during entrucking simultaneously, each only controls cornerwise two wheels respectively, certainly the trailing wheel of some Light-duty Vehicle is two groups of two wheels side by side, this group wheel is controlled by same the utility model with cornerwise front-wheel, and this is because the hydraulic braking pipe also is to constitute by two groups.
Pick out hole 3 and hydraulic pressure system by what two connection pipes connected this device during installation.
