Background technology
Because the gross mass and inertia of commercial car are big, when running into long descending road conditions, driver must frequently or continuously step on
Brake, to reduce speed, it is ensured that safety, the time one is grown, brake block can serious wear, appearance " heat is weak " phenomenon.Produced during brake
Raw high temperature also results in a series of problem, such as：Brake drum brake such as splits, blown out at the accident etc..Auxiliary braking is exactly to be used for solving
The system configuration of this contradiction, the energy produced when it is by descending is consumed by other forms, so that speed be dropped to properly
Scope.So it is no longer needed for driver frequently or continuously touches on the brake, so as to reduce skidding access times, reduces master
The abrasion of friction brake system.
Complemental brake system mainly has retarder, engine brake and exhaust brake valve of engine.With regard to its retardation efficiency
For, retarder is best, but price is most expensive.Current commercial car using it is more be exhaust brake valve of engine, its advantage is valency
Lattice are cheap, simple in construction, be easy to arrangement.
Chinese patent：Authorization Notice No. is CN205654436U, and authorized announcement date is new for the practicality on October 19th, 2016
Type patent discloses a kind of exhaust brake dish valve, including blast pipe and valve body, and blast pipe one end is connected with the gas outlet of booster,
The other end is connected with the air inlet on valve body, i.e., the dish valve is arranged in the blast pipe behind booster.During exhaust brake, butterfly valve
Exhaust duct is closed, high back pressure can be produced in blast pipe, prevents piston from compressing, work done during compression is absorbed, the rise of pressure can influence to increase
The service life of depressor, or even oil leak can be caused because poorly sealed.
The content of the invention
High back pressure when the purpose of this utility model is the exhaust brake for overcoming prior art to exist in blast pipe is easily damaged
The problem of evil booster, there is provided the band exhaust brake dish valve that a kind of high back pressure that can be prevented effectively from blast pipe damages booster
The exhaust pipe of engine.
To realize object above, the technical solution of the utility model is as follows：
A kind of exhaust pipe of engine with exhaust brake dish valve, including the exhaust pipe of engine, exhaust brake dish valve, the row
Gas disc brake valve include valve block, can be with moving valve plate relative to the rotating shaft that the exhaust pipe of engine rotates；
The exhaust end of the exhaust pipe of engine is communicated with the inlet end of booster, and the valve block, rotating shaft, which are respectively positioned on, starts
The inside of machine blast pipe, and one end of rotating shaft is fixedly connected with the inwall of the exhaust pipe of engine, the other end of rotating shaft radially across
It is fixedly connected after the exhaust pipe of engine with the connecting rod outside the exhaust pipe of engine.
The exhaust pipe of engine is pulse type gas exhausting pipe.
Sealing gasket is provided between the rotating shaft and the exhaust pipe of engine, the sealing gasket passes through outside the exhaust pipe of engine
The pressing plate in portion is fixed.
The valve block is riveted in rotating shaft.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model a kind of exhaust end and the inlet end of booster of the exhaust pipe of engine with exhaust brake dish valve
Communicate, i.e., move to exhaust brake dish valve in the blast pipe before booster, when can be prevented effectively from exhaust brake in blast pipe
High back pressure infringement booster, meanwhile, valve block, rotating shaft are respectively positioned on the inside of the exhaust pipe of engine, and rotating shaft one end with starting
The inwall of machine blast pipe is fixedly connected, and the other end of rotating shaft is radially across after the exhaust pipe of engine and outside the exhaust pipe of engine
The connecting rod in portion is fixedly connected, and the design enables dish valve to close discharge duct by rotating in damped condition, plays auxiliary
The effect of braking is helped, and in non-brake operating mode then as the central dividing plate of blast pipe, does not interfere with the exhaust of engine, not only
It is simple in construction, and retardation efficiency is higher.Therefore, high back pressure when the utility model not only avoid exhaust brake in blast pipe
Booster is damaged, and simple in construction, retardation efficiency is higher.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the utility model under non-exhaust brake operating mode.
Fig. 3 is structural representation of the utility model under exhaust brake operating mode.
In figure：The exhaust pipe of engine 1, exhaust brake dish valve 2, valve block 21, rotating shaft 22, connecting rod 3, sealing gasket 4, pressing plate 5.
Embodiment
Explanation and embodiment are described in further detail to the utility model below in conjunction with the accompanying drawings.
