Description
Technical field
The utility model relates to the brake system of car field, relates in particular to a kind of gas-fueled vehicles exhaust braking.
Background technique
The automobile exhaust braking device is a kind of auxiliary brake device for automobile, is connected on usually on the car load outlet pipe.Generally, the many couplings of the heavy vehicle that inertia is big have the automobile exhaust braking device, use during for car load lower long slope or abrupt slope.Its objective is and reduce the speed of a motor vehicle, guarantee car load safety and improve break working life.During the work of automobile exhaust braking device, the butterfly valve in the exhaust braking cuts out, and the outlet pipe of automobile is plugged, thereby the back pressure of motor is increased, and at this moment, motor is in the anti-state that drags, not externally acting.Motor becomes atmospheric pump by power source, consumes to come from the power that the car load descending produces, thereby reaches the purpose that reduces the speed of a motor vehicle.
Yet DENG is different on plenum system with premixed motor.DENG gets into is pure air and does not have throttling arrangement.When exhaust braking worked, compressed media can not receive throttling arrangement and hinder, and still can get into cylinder.And the mixed combustible gas body that premixed natural gas engine gets into needs throttling arrangement to regulate air inflow, to reach the effect of control engine load.If premixed motor adopts the exhaust braking of DENG, when exhaust braking was worked, in a single day throttling arrangement cut out, and compressed media just can't get into cylinder, and exhaust braking was lost efficacy.Thereby present exhaust braking is not suitable for premixed natural gas engine, need the exhaust braking of premixed natural gas engine be designed again.
Therefore, be necessary to provide a kind of gas-fueled vehicles exhaust braking to overcome above-mentioned defective.
The model utility content
The purpose of the utility model provides and a kind ofly can satisfy car load auxiliary braking demand, simple in structure, easy for installation, travel safety is high and brake wear is little gas-fueled vehicles exhaust braking.
To achieve these goals; The utility model provides a kind of gas-fueled vehicles exhaust braking to comprise exhaust braking valve, suction tude, closure, TPS, exhaust brake request switch, suction tude control valve and electronic controller; Exhaust braking valve is installed in the automobile exhaust pipe; Suction tude is connected with cylinder; Closure is installed on the passage of suction tude, and TPS is installed on the closure, and the suction tude control valve is installed on another passage of suction tude; Two input ends of electronic controller are connected with exhaust brake request switch with TPS respectively, and two output terminals of electronic controller are connected with exhaust braking valve with the suction tude control valve respectively.
Preferably, exhaust braking valve and suction tude control valve are butterfly valve.
Preferably, suction tude is the Twin channel suction tude.
Compared with prior art; Because the suction tude of the utility model automobile exhaust braking device has two passages, first passage can be used as the suction port of combustion gas, and second passage can be used as the suction port of air; When automobile carries out exhaust brake; First pathway closure can get in the cylinder through second passage through the unlatching of suction tude control valve as the air of compressed media, thereby satisfies the requirement of gas-fueled vehicles exhaust brake.In addition, the utility model simple in structure, easy for installation, travel safety is high and brake wear is little.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model gas-fueled vehicles exhaust braking.
Embodiment
With reference now to accompanying drawing, describe the embodiment of the utility model, the similar elements label is represented similar elements in the accompanying drawing.
With reference to figure 1, present embodiment gas-fueled vehicles exhaust braking comprises exhaust braking valve 10, suction tude 20, closure 30, TPS 40, exhaust brake request switch 50, suction tude control valve 60 and electronic controller 70.Exhaust braking valve 10 is installed in the automobile exhaust pipe (not shown); Suction tude 20 is connected with cylinder 80; Closure 30 is installed on the first passage 21 of suction tude 20; TPS 40 is installed on the closure 30, and suction tude control valve 60 is installed on the second channel 22 of suction tude 20.Two input ends of electronic controller 70 are connected with exhaust brake request switch 50 with TPS 40 respectively, and two output terminals of electronic controller 70 are connected with exhaust braking valve 10 with suction tude control valve 60 respectively.Preferably, exhaust braking valve 10 is butterfly valve with suction tude control valve 60, and suction tude 20 is the Twin channel suction tude.
Below in conjunction with Fig. 1 the working principle of the utility model is done a detailed explanation.
When automobile is in descending or abrupt slope, close the throttle, to close the first passage of suction tude, simultaneously, the driver gives electronic controller through the signal that exhaust brake request switch sends the request braking.Then; Electronic controller sends shutdown signal control exhaust braking valve and cuts out; And send start signal control suction tude control valve and open; Opening the second channel of suction tude, get in the cylinder through second channel as the air of compressed media, thereby utilize the kinetic energy compressed air to do work of automobile itself.
When automobile need cut out exhaust brake, opening throttle, to open the first passage of suction tude, simultaneously, the driver sends the signal that withdraws from braking through exhaust brake request switch and gives electronic controller.Then, electronic controller sends start signal control exhaust brake opening of valves, and sends shutdown signal control suction tude control valve and close, and to close the second channel of suction tude, like this, automobile gets into the state of cruising.
By on can know; Because the suction tude 20 of the utility model automobile exhaust braking device has two passages, first passage 21 can be used as the suction port of combustion gas, and second passage 22 can be used as the suction port of air; When automobile carries out exhaust brake; First passage 21 is closed, and can get in the cylinders through second passage 22 through the unlatching of suction tude control valve 60 as the air of compressed media, thereby satisfies the requirement of gas-fueled vehicles exhaust brake.In addition, the utility model simple in structure, easy for installation, travel safety is high and brake wear is little.
More than combine most preferred embodiment that the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains modification, the equivalent combinations of carrying out according to the essence of the utility model.
