Abstract
The utility model relates to an adjustable exhaust brake, comprising an exhaust pipe, a butterfly valve controlled by a rotation gear in the exhaust pipe, a through hole provided on the pipe wall between the air intake of the exhaust pipe and the butterfly valve, and an over-pressure protection assembly in the through hole. When the pressure in the exhaust pipe exceeds the setting pressure in unexpected circumstances, the utility model can release the pressure timely and protect the exhaust brake working cylinder, rotation gear and other moving parts and sealing parts from damage; and is convenient and practical in that the opening pressure that regulates the over-pressure protection assembly is adjustable.
Description
Technical field
The utility model relates to a kind of adjustable exhaust braking.
Background technique
At present, when vehicle need slow down, particularly operate in when mountain area and city bus needs are frequent to be braked, the driver uses foot brake usually or adopts gear shift low speed to bring into play the engine braking effect, but frequently use foot brake the brake-fade phenomenon can occur, kickdown utilizes engine braking can make the running of the passive overspeed of motor, to bringing certain influence in working life of vehicle.So modern big or middle be on the heavy vehicle of power source exhaust braking to be housed mostly with the diesel engine, complemental brake system as vehicle, it is installation-fly valve and a rotating mechanism in engine exhaust pipe, increase the exhaust stroke resistance by closing this fly valve, the exhaust that utilizes motor is as auxiliary braking, thus raising vehicle braked effect.Yet dress with the Diesel Engine Exhaust Pipe of exhaust braking normally according to exhaust gas temperature, air pressure with and back pressure design, do not consider the abnormal conditions that outlet pipe excessively increases because of the obstruction build-up of pressure when adopting exhaust braking, and the generation of this abnormal conditions can cause the damage of movable parts such as exhaust braking working cylinder, fly valve and rotating mechanism and sealed member thereof.
The model utility content
When the purpose of this utility model just provides a kind of outlet pipe excessive pressure and increases, the timely adjustable exhaust braking of release pressure.
The technological scheme that realizes the utility model purpose is: the utility model comprises outlet pipe, is provided with the fly valve by rotating mechanism control in the outlet pipe, is provided with through hole on the tube wall between outlet pipe suction port and the fly valve, is provided with overvoltage protective module in the through hole.
The overvoltage protective module of above-mentioned adjustable exhaust braking comprises the spool that is arranged on outlet pipe tube wall through hole inner end and the valve gap of outer end, is provided with stage clip between spool and the valve gap, and valve gap is provided with through hole.
The outlet pipe tube wall through hole of above-mentioned adjustable exhaust braking is the little stepped shaft through hole in big inner end, outer end.
The spool of the overvoltage protective module of above-mentioned adjustable exhaust braking is a ball.
The valve gap of the overvoltage protective module of above-mentioned adjustable exhaust braking is a hollow bolt, and valve gap is connected with outlet pipe tube wall through hole whorl.
Be provided with the ball trim ring between the spool of above-mentioned adjustable exhaust braking and the stage clip.
The outlet pipe tube wall through hole inner end of above-mentioned adjustable exhaust braking and the hole wall of spool cooperation place are the conical surface.
The utlity model has positive effect: (1) the utility model is provided with overvoltage protective module on the tube wall between outlet pipe suction port and the fly valve; when fortuitous event causes the outlet pipe excessive pressure to increase; timely release pressure guarantees that movable part such as exhaust braking working cylinder, rotating mechanism and sealed member thereof are not damaged.(2) valve gap of overvoltage protective module is connected with through hole whorl on the outlet pipe tube wall, the distance between rotatable adjusting and the spool, thus the cracking pressure of regulating overvoltage protective module is convenient and practical.
Description of drawings
