Tracheae.
Background technique
With the increasing demand for brake systems for commercial vehicles, only relying on cannot be complete to traditional braking system upgrading
Meet the use demand of client, so the auxiliary braking that come into being, although auxiliary braking is not achieved primary brake system and exports that
Big brake force, but when vehicle needs to slow down in the process of moving, had both reduced the abrasion of friction plate using auxiliary braking, also
The effect of braking deceleration can be played, exhaust brake is a kind of retarding braking of auxiliary driving braking action, and structure is simple, price
Cheaply, it is widely used on diesel-powered truck or car, exhaust and brake system is usually to arrange in engine
One exhaust brake butterfly valve is installed, when exhaust brake does not work, valve block opens, exhaust pipe is connected, and has no effect on hair at tracheae
The normal work of motivation；When exhaust brake is active, the cylinder for braking butterfly valve receives the energy from engine, in cylinder
Piston pushes shaft rotation, to make valve block close, exhaust blockage, while the confession of the mandatory cutting engine of oil-break mechanism
Oil, the automobile of traveling drive engine crankshaft rotation, and engine piston is in instroke, and the gas of discharge is because of braking valve block pass
It closes and is compressed, generate pressure, engine is made to work as compressor, gas compressed produces piston stroking upward when exhaust
Raw resistance, increases the loss of calming the anger of engine, to play braking effect, braking butterfly valve in the prior art is working
When valve block is opened, exhaust pipe conducting pushes valve block to close, if cylinder in braking using power modes such as pistons in cylinder
Equal power parts damage, not only valve block cannot play auxiliary braking, can also accelerate the unimpeded of exhaust, and it is not very practical, and
The component being arranged in exhaust pipe is complicated, and the resistance for only resulting in exhaust increases, and influences normally to use, and provides a kind of structure letter
Single, at low cost, long service life, the small and practical exhaust pipe of engine with exhaust brake butterfly valve of exhaust resistance are very
It is necessary to.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of structure it is simple, it is at low cost, make
With the service life is long, the small and practical exhaust pipe of engine with exhaust brake butterfly valve of exhaust resistance.
Purpose of the utility model is realized as follows: a kind of exhaust pipe of engine with exhaust brake butterfly valve, it includes
Tube body, the intracorporal center of the pipe are vertically arranged with shaft, the shaft two sides be respectively articulated with the first valve block and
Second valve block is provided with baffle, first valve block and the second valve block on the outside of first valve block and the second valve block
Inside be respectively arranged with first support and second support, the first support and second support are fixed on by elastomeric element
In shaft.
There are certain gaps between first valve block and inboard wall of tube body.
There are certain gaps between second valve block and inboard wall of tube body.
The first support, second support are set as being fixedly connected with the connection of elastomeric element.
The elastomeric element is socketed in shaft.
The utility model has the beneficial effects that the utility model is provided with shaft, shaft two sides are hinged with the first valve block and
It is provided with baffle on the inside of two valve blocks, the first valve block and the second valve block, is provided on the outside of the first valve block and the second valve block
One bracket and second support, first support and second support are fixed in shaft by elastomeric element, during the work time, exhaust
Air pressure on the inside of pipe pushes the first valve block and the second valve block to open, and exhaust pipe enters working condition, if engine stop works, row
It is pushed without air pressure on the inside of tracheae, then under the action of elastomeric element on the outside of exhaust pipe, the first valve block and the second valve block return automatically
To original state, baffle plays the role of limit to the first valve block and the second valve block, and the first valve block and the second valve block will not be made super
Out original state and keep braking effect bad, when there is ponding on the road, and can prevent the water on the outside of exhaust pipe from entering inside, influence
The exhaust pipe internal structure of normal use, the present apparatus is simple, can reduce exhaust resistance, can carry out just to the component in exhaust pipe
Prompt replacement, practical, the utility model has simple structure, at low cost, long service life, exhaust resistance small and practicability
Strong advantage.
