Abstract
The utility model relates to a device for a trailer brake. The utility model comprises a trailer primordial qi brake. The trailer primordial qi brake is additionally provided with a hand-brake valve H'. An air supply opening of the hand-brake valve H' is connected in parallel with an air supply opening of a trailer braking valve J. An air-out opening of the hand-brake valve H' is connected in parallel with a control opening of the trailer braking valve J. A bi-pass non-return valve Q is connected in series between the air-out opening of the hand-brake valve H' and the control opening of the trailer braking valve J. A non-return valve R is connected in series in the front of an air-in opening of a parking brake valve H and an air-in opening of a relay valve 1. The utility model can carry out air braking and hand braking on the trailer according to actual vehicle condition, and efficaciously avoid the faults that a main vehicle is impacted, or a main trailer is folded, etc., because of the trailer brake lag.
Description
The utility model belongs to the brake system of car technical field, is specifically related to a kind of brake equipment that is used for trailer braking protection valve.
Drawbar trailer is easier to the phenomenons such as collision, main trailer folding of breakking away take place at the glancing impact ratio, mainly is because defective is mated in the braking of main car and trailer, i.e. the main relatively car of the braking of trailer lags behind and causes.The brake equipment of modern automobile mostly is the dual circuit system, is made up of air brake valve, stopping brake valve, relay valve, trailer braking valve, trailer emergency relay valve and Air compressor, pressure regulating valve, four path distribution valves, each air receiver and compressed air brake cylinder.Handle trailer braking valve by air brake valve, and then handle the braking of trailer by the trailer emergency relay valve.In trailer braking valve and the trailer emergency relay valve air pressure advance mechanism is set, the lead setting of these mechanisms in use is unalterable (mixes up before being dispatched from the factory by valve class producer assembling usually or design of Structural Parameters is determined).And automobile situation such as road and load in real-world operation varies, and the concrete structure of different trailer brake systems is also different, single unmodified drawbar trailer braking advanced device just is difficult to satisfy the needs of different situations, cause above-mentioned phenomenon, greatly influence the safety of drawbar trailer.
The purpose of this utility model is exactly the above-mentioned deficiency at existing trailer braking protection valve device, providing a kind of can in time carry out compressed air brake and hand braking trailer braking protection valve device according to actual vehicle condition, effectively avoids the trailer braking protection valve hysteresis to collide accidents such as main car or main trailer discounting.
The technical solution of the utility model is as follows:
The trailer braking protection valve device, it comprises by air brake valve G, stopping brake valve H, relay valve I, trailer braking valve J, trailer emergency relay valve K, and Air compressor A, pressure regulating valve B, four path distribution valve G, the former Pneumatic braking device of trailer that each air receiver D, E, F, L and compressed air brake cylinder are formed has been set up a hand brake valve H ' in the device, the air supply opening of hand brake valve H ' is in parallel with trailer braking valve J air supply opening, and the air extractor duct of hand brake valve H ' is in parallel with trailer braking valve J control mouth; Hand brake valve H ' air extractor duct is to bilateral check valve Q of series connection between the trailer braking valve J control mouth, check valve R of series connection before stopping brake valve H admission port and relay valve I admission port.
Hand brake valve in this device has the servo-actuated characteristic of boosting.
The advantage of this device is:
1. kept the compressed air brake performance of original device, and be equipped with hand brakingly, solved coordination, the matching problem of braking of main car and trailer braking protection valve, thereby can avoid collision and discounting accident main, trailer, raising travel safety effectively.
2. can shorten the train braking distance effectively, reduce the braking number of times, thereby reduce the wearing and tearing of brake strip.
3. after adopting this device, can reduce the advanced device in former trailer braking valve and the trailer emergency relay valve, to reduce the cost of whole device.
4. hand braking part-structure is succinct, can be parallel to easily in the brake system of former car.
Below in conjunction with drawings and Examples this device is elaborated:
Fig. 1 is this apparatus structure scheme drawing.
Fig. 2 is a trailer hand brake valve air pressure characteristic map.
Among the figure: A-Air compressor, B-pressure regulating valve, C-four path distribution valves, G-air brake valve, H-stopping brake valve are led in D, E, F, L-gas storage, H '-trailer hand brake valve, I-relay valve, J-trailer braking valve, K-trailer emergency relay valve, compressed air brake cylinder before the M-, compressed air brake cylinder behind the N-, O-trailer braking protection valve air chamber, the auxiliary gas, Q-bilateral check valve, R-check valve used of P-.
Embodiment:
As shown in Figure 1, this device has kept the entire infrastructure of existing tractor truck Pneumatic braking device, promptly by air brake valve G, stopping brake valve H, relay valve I, trailer braking valve J, trailer emergency relay valve K, and Air compressor A, pressure regulating valve B, four path distribution valve C, each air receiver D, E, F, L and compressed air brake cylinder constitute former Pneumatic braking device, promptly dotted line connecting bridge among the figure increases hand brake valve H ', bilateral check valve Q and check valve R in addition newly.I.e. solid line connecting bridge among the figure.The air supply opening 1 of hand valve H ' is in parallel with the air supply opening 11 of trailer braking valve J, and the air extractor duct 2 of hand valve H ' is in parallel with the control mouth 42 of trailer braking valve J.For making trailer manually partly not influence the compressed air brake performance, the air extractor duct 2 of hand valve H ' farthest reduces the interactive air pressure of the hand braking and main car compressed air brake of trailer with this and switches sudden change to series connection one bilateral check valve Q between the control mouth 42 of trailer braking valve J.Gas refluence causing spring release braking for preventing that hand valve H ' operation causing air receiver F air pressure from descending and causing brake application by spring air chamber N spring air cavity was in series with a check valve R before the admission port 1 of hand brake valve H ' admission port 1 and relay valve I.
Certainly, for fear of the excessive braking of trailer and locking, the peak output air pressure of trailer hand brake valve H ' air extractor duct 2 should be not too high, should look factor such as trailer total mass and suitably select.The peak output air pressure of trailer hand brake valve as shown in Figure 2 is 3.3bar, is applicable to the drawbar trailer about 40 tons.
Originally caring for manipulating mainly of vehicle brake depends on the circumstances: when feeling to hang with when colliding main car, give one in trailer suitable hand braking to eliminate; When tractor-trailer train when sliding (particularly descending) road is turned on the road, suitably hand braking trailer, help the driving states that keeps good, be beneficial to safety; When emergency brake, and then the braking trailer brakes train earlier, not only can prevent phenomenons such as the folding whipping of main trailer, also can shorten stopping distance, improves the insensitivity of train.Certainly, the installation site of trailer hand brake valve should be satisfied easy to operate, can not interfere with other operational motion, and this is the basic assurance that can bring into play the hand braking effect of trailer in emergency brake.
