Description
Technical field
The utility model relates to Vehicular brake device, belongs to a kind of double loop air braking systems especially.
Background technology
At present the double loop air braking systems that uses on the domestic automobile all is that each group wheel has and overlaps independently pneumatic circuit, and promptly each compressed air brake cylinder only connects a pneumatic circuit.When a loop et out of order is wherein arranged, just lost braking potential with this loop-coupled compressed air brake cylinder, cause brake wheel quantity to reduce, braking force reduces, and even more serious person jeopardizes user's life security because of brake failure.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and a kind of single air chamber double loop air braking systems is provided, when both having made wherein a brake piping et out of order, each compressed air brake cylinder still can normal operation, can effectively realize braking in time.
The utility model is achieved by the following technical solution: it comprises relay valve, the gentle pressure-controlled pipeline of the compression air brake pipeline that communicates with relay valve, the total jar of pressure of pressure gas is provided for pipeline, the control cock of control air pressure pilot piping, compressed air brake cylinder, have two compressed air brake cylinders that air pressure screening plant-shuttle valve respectively is installed, the two ends of each shuttle valve communicate with two relay valves respectively, relay valve respectively with two independently the compression air brake pipeline communicate.
Shuttle valve can independently be selected high one of air pressure in the compression air brake pipeline at two as the air pressure screening plant, it is acted on the compressed air brake cylinder, and the pipeline that another is out of order or air pressure is lower is closed.The utility model has not only been realized the double loop safety arrestment of cycle bridge power actuated vehicle, and is applied in the time of also can avoiding braking et out of order on the multi-axle automobile, because of brake wheel reduces caused potential safety hazard.
The concrete characteristics of this programme also have, and described control cock adopts the two-chamber control cock, two air cavitys of two-chamber control cock respectively with two independently the air pressure pilot piping an end respectively with communicate, the other end of each air pressure pilot piping communicates with two relay valves respectively.The total jar of described pressure branches out two pressure and divides jar, the other end that each pressure divides jar respectively with two independently the compression air brake pipeline communicate.Two air cavitys of described two-chamber control cock divide jar to be communicated with two pressure respectively.
This utility model has been installed on power actuated vehicle, when user's push down on the pedal, open simultaneously with air pressure pilot piping bonded assembly two-chamber control cock, the air pressure pilot piping utilizes high pressure gas to open relay valve simultaneously, make high pressure gas from the shortest compression air brake pipeline, inject shuttle valve, one that shuttle valve selection pressure in two independent compression air brake pipelines is bigger is passed through, and makes the gas in the brake piping of connection directly affact on two compressed air brake cylinders the balance safety arrestment of two wheels about realization.If a pipeline et out of order or air pressure deficiency are wherein arranged, can not influence another pipeline and work, and braking warning and air-pressure gauge can inform in time that problem has appearred in which bar pipeline of user.
The beneficial effect of this programme can learn according to the narration to such scheme, adopts the utility model, can improve vehicle safety, through the special verification experimental verification of automobile repeatedly, and the utility model dependable performance, safe and practical.
By narration to such scheme, the utlity model has substantive distinguishing features and progress as can be seen, it is creative to be conclusive.
Description of drawings
Fig. 1 is the utility model double loop control principle figure.
Fig. 2 is the utility model double loop screening schematic diagram.
Wherein, 1, the 6-relay valve, 2, the 5-shuttle valve, 3, the 4-compressed air brake cylinder, 7,8-air pressure pilot piping, 9, the two-chamber control cock, 10, pedal, 11, Air compressor, 12, total jar of pressure, 13,14-pressure divides jar, 15,16-compression air brake pipeline.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
As can be seen from Figure 1 the utility model overlaps independently compression air brake pipeline (15) and (16), two by two and overlaps that independently air pressure pilot piping (7) and (8) and dual circuit screening plant-shuttle valve (2) and (5) three parts are formed.
As shown in Figure 1 and Figure 2, shuttle valve (2) and (5) directly are fixed on compressed air brake cylinder (3) and (4) upward and with it communicate, the two ends of shuttle valve (2) and (5) communicate with relay valve (1) and (6) respectively, and independently compression air brake pipeline (16) and (15) communicate with two respectively for relay valve (1) and (6).And air pressure pilot piping (8) and (7) of control relay valve (1) and (6) also are separate, and an end of air pressure pilot piping (7) and (8) communicates with two air cavitys of two-chamber control cock (9) respectively, and the other end communicates with relay valve (6) and (1) respectively.With pilot piping (7) and (8) bonded assembly two-chamber control cock (9) be one, two air cavitys of two-chamber control cock (9) divide jar (13), (14) to be communicated with pressure respectively, one end of compression air brake pipeline (15) and (16) divides jar (13), (14) to communicate with pressure respectively, and pressure divides the other end of jar (13), (14) all to communicate with pressure total jar (12).When push down on the pedal, pilot piping (7) and (8) can be opened relay valve (6) and (1) simultaneously, high pressure gas is known from experience injection shuttle valve (2) and (5) from the shortest compression air brake pipeline (15) and (16), two shuttle valves respectively in two independent compression air brake pipelines bigger one of selection pressure pass through, make the gas in the brake piping of connection directly affact on two compressed air brake cylinders the balance safety arrestment of two wheels about realization.
As can be seen from Figure 1, when wherein having a pipeline to break down, such as with relay valve (1) bonded assembly pipeline wherein one fault has appearred, then just might lose efficacy by an end chargine line in shuttle valve (2) and (5), but other end normal operation, then can provide high pressure gas for compressed air brake cylinder (3) and (4) equally, implement braking.
Foot feed two-chamber control cock in the utility model specific embodiment.After the user unclamped pedal, relay valve (1) and (6) were closed, and the air in the compressed air brake cylinder can pass through shuttle valve (2) and (5) back exhaust to atmosphere, brake off.
