Abstract
The utility model provides a novel automobile exhaust braking device. The device comprises a gas storage cylinder and an exhaust braking gas cylinder; a gas outlet of the gas storage cylinder is respectively connected with a gas inlet of the exhaust braking gas cylinder and two gas inlets of a shuttle valve through pipelines; a gas outlet of the shuttle valve is connected with a gas inlet of a fuel cut-out gas cylinder; a braking electromagnetic valve I and a flameout electromagnetic valve II are respectively connected in series on the pipeline between the gas outlet of the gas storage cylinder and the two gas inlets of the shuttle valve; an exhaust braking switch controls the electromagnetic valve I; and a flameout switch controls the electromagnetic valve II. In the utility model, when an automobile goes down a slope, a gearbox is put into a certain gear and an engine is cut out of fuel and shut down, and the exhaust braking cylinder of the engine blocks an exhaust pipe, so that the resistance of the engine is utilized to consume the automobile kinetic energy, automobile deceleration is achieved, the abrasion between a brake friction plate and tires is reduced, the safety braking performance of the whole automobile is improved, and the fuel-saving effect is obvious.
Description
Technical field
The utility model belongs to brake system of car manufacturing technology field, is specifically related to a kind of new automobile exhaust braking.
Background technique
At present cargo vehicle is all taked the auxiliary braking mode of exhaust brake when descending, though when the method has realized the vehicle descending effectively slow, reduce brake wear, wheel heating, improve traffic safety; But motor carries out exhaust brake under idling mode, consume a large amount of oil plants, contaminated air; If the employing step-by-step operation, first exhaust brake, oil-break brings inconvenience to driver's operation again.
The model utility content
The technical problem that the utility model solves: a kind of new automobile exhaust braking is provided, automobile is when descending, gearbox is hung into certain gear and the motor oil-break is flame-out, the engine exhaust and brake cylinder is blocked outlet pipe, utilize engine drag to consume automobile kinetic energy, realize car deceleration, reduce brake bush and Tyte Wear, improve the safety braking performance of car load, and oil-saving effect is obvious.
The technical solution adopted in the utility model: a kind of new automobile exhaust braking, comprise gas cylinder and exhaust brake cylinder, the air outlet of gas cylinder is connected with the suction port of exhaust brake cylinder and two suction ports of shuttle valve respectively by pipeline, the air outlet of shuttle valve is connected with the suction port that stops oil gas cylinder, and be connected in series braking electromagnetic valve I and flame-out electromagnetic valve II respectively on the pipeline between two suction ports of the air outlet of gas cylinder and shuttle valve, exhaust brake switch control electromagnetic valve I, flameout switch control electromagnetic valve II.
Two control ends of described electromagnetic valve I are connected with the two ends of storage battery and exhaust brake indicator lamp respectively, and exhaust brake switch is connected on the circuit between storage battery and the exhaust brake indicator lamp; Two control ends of electromagnetic valve II are connected with the two ends of storage battery respectively, and are in series with flameout switch between electromagnetic valve II and the storage battery.
When the utility model has compared with prior art not only been realized the vehicle descending effectively slow, reduce brake wear, wheel heating, improve traffic safety, and oil-saving effect is obvious, has protected environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
A kind of new automobile exhaust braking comprises gas cylinder 1 and exhaust brake cylinder 2.The air outlet of gas cylinder 1 is connected with the suction port of exhaust brake cylinder 2 and two suction ports of shuttle valve 3 respectively by pipeline, the air outlet of shuttle valve 3 is connected with the suction port that stops oil gas cylinder 4, and be connected in series braking electromagnetic valve I 5 and flame-out electromagnetic valve II 6 respectively on the pipeline between two suction ports of the air outlet of gas cylinder 1 and shuttle valve 3, exhaust brake switch 7 control electromagnetic valve I 5, flameout switch 8 control electromagnetic valve II6.
Two control ends of described electromagnetic valve I 5 are connected with the two ends of storage battery 9 and exhaust brake indicator lamp 10 respectively, and exhaust brake switch 7 is connected on the circuit between storage battery 9 and the exhaust brake indicator lamp 10; Two control ends of electromagnetic valve II 6 are connected with the two ends of storage battery 9 respectively, and are in series with flameout switch 8 between electromagnetic valve II 6 and the storage battery 9.
Working procedure: when automobile lower long slope, abrupt slope, this moment, motor was in the forced idling situation, closed exhaust brake switch 7 makes switch be on state, exhaust brake indicator lamp 10 is lighted, the coil electricity of electromagnetic valve I 5 makes its conducting, pressurized air in the gas cylinder 1 charges into exhaust brake cylinder 2 by pipeline through this solenoid valve increases the cylinder internal resistance, and engine speed reduces, and plays the effect that reduces the speed of a motor vehicle.Pressurized gas charges into through shuttle valve 3 and stops in the oil gas cylinder 4 simultaneously, stops oil gas cylinder 4 work, cuts off the oil circuit of motor.Thereby realize exhaust brake pressure oil-break.Behind descending or travel on normal road surface, disconnect exhaust brake switch 7, exhaust brake, force oil-break to be removed simultaneously.
Closed flameout switch 8 makes the coil electricity of electromagnetic valve II 6 make its conducting when switch-off, and the pressurized gas in the gas cylinder 1 charges into through this solenoid valve and shuttle valve 3 by pipeline and stops in the oil gas cylinder 4, stops oil gas cylinder 4 work, cuts off the oil circuit of motor, engine misses.
The utility model exhaust brake cylinder is with to stop oil cylinder in parallel by threeway, and before stopping oil gas cylinder, connect a shuttle valve 3, thereby by to stopping the two-way control of oil gas cylinder, realize stopping oil gas cylinder when exhaust brake and exhaust brake cylinder co-operation, when switch-off, stop oil gas cylinder and work independently.
