Abstract
The utility model discloses a gas exhaust braking valve, which comprises a valve body, a valve sheet, a rotating shaft, a cylinder and a push rod, wherein the valve sheet is connected to the rotating shaft; the rotating shaft is supported in the inner cavity of the valve body; the operation end of the rotating shaft is connected with the push rod; and the other end of the push rod is connected with the cylinder. A design that the rotating shaft and the valve body are eccentric is adopted; in a process of braking, the gas exhaust braking valve of an engine is closed, the back pressure of the engine is increased to a certain value, at the moment, and the upper part and the lower part of the valve sheet bear different pressures, so that rotating torques are produced, and the valve sheet of the gas exhaust braking valve is opened, the two torques are balanced, and then the back pressure can be always stabilized at a proper value so that the loss of the engine caused by overhigh back pressure can be reduced; and furthermore, continuous braking can be realized by effectively using the automobile kinetic energy absorbed by an engine. The novel gas exhaust braking valve is easy to produce and machine; the production cost is effectively reduced; and the shortcoming that the engine is damaged because of over-high back pressure, can be overcome. The utility model also provides an automobile adopting the braking valve.
Description
Technical field
The utility model relates to a kind of novel exhaust brake valve and adopts the automobile of this brake valve.
Background technique
At present, in the car load braking system, except that adopting skidding, the also normal exhausting waste gas pipeline that kills engine that adopts, the device that makes motor set up back pressure and then utilize this back pressure realization to brake.The exhaust braking valve of exhausting waste gas pipeline is used in the existing technology to kill engine; Its valve body and valve block are generally eccentric structure; The back pressure that when outlet valve is worked, produces is quite big, even greater than the specified value of engine back pressure, the high back pressure value can cause failure of engine components to influence its working life.
The patent No. is that the utility model patent of ZL200720086858.X discloses a kind of not damaged motor novel exhaust brake valve; Accompanying drawing 3 is the structural representation of this exhaust braking valve; Its valve body comprises valve 10, valve shaft 9, and the off-centre of this brake valve is on valve body 8, therefore needs to guarantee the concentricity in valve body hole about in the of 8; The off-centre and the valve body 8 that also will guarantee valve 10 are synchronous; Guarantee that with this valve 10 and valve body 8 do not have the gap when closing, this technological scheme causes the processing of valve member and assembly technology strict, causes its production and installation cost higher.
The model utility content
The utility model provides a kind of novel exhaust brake valve; Not only effectively solve the impaired problem of the excessive caused motor of engine back pressure; Improved the eccentric structure of eccentric exhaust braking valve simultaneously, guaranteed more easily in process of production to reduce production costs throw of eccentric.
The utility model also provides a kind of automobile that adopts this brake valve.
The technological scheme of the novel exhaust brake valve of the utility model is following: a kind of exhaust braking valve, have valve body, valve block, rotating shaft, cylinder, push rod, and valve block is connected in the rotating shaft; Rotating shaft is supported in the inner chamber of valve body, and the operating end of rotating shaft is connected with push rod, and the other end of push rod connects piston; Piston places in the cylinder; The cylinder head end has suction port, also is connected with bent axle between rotating shaft operating end and the push rod, and parts such as bent axle, push rod, piston, cylinder all are fixed on the support in the valve body outside.
Preferably, said valve block is connected in the rotating shaft through screw, nut.
Preferably, between said screw and valve block compression spring is housed.
Preferably, said valve block is along said body cavity radial arrangement.
Preferably, said valve block adopts arranged off-centre in valve body.
Preferably, said rotating shaft is along the radial arrangement of said body cavity.
Preferably, said rotating shaft adopts eccentric structure to arrange in said valve body, i.e. the lumen shaft line parallel of the axis of said rotating shaft and valve body has a suitable distance between two axial lines.
Second aspect of the utility model provides a kind of automobile; It adopts the exhaust braking valve according to the utility model; Said novel exhaust brake valve comprises aforesaid valve body, valve block, rotating shaft, cylinder, push rod, and said valve block is connected in the said rotating shaft, and said rotating shaft is supported in the inner chamber of valve body; The operating end of said rotating shaft is connected with said push rod, and the other end of said push rod connects cylinder.
Preferably, said valve block is connected in the rotating shaft through screw, nut.
Preferably, between said screw and valve block compression spring is housed.
Preferably, said valve block is along said body cavity radial arrangement.
Preferably, said valve block adopts arranged off-centre in valve body.
Preferably, said rotating shaft is along the radial arrangement of said body cavity.
Preferably, said rotating shaft adopts eccentric structure to arrange in said valve body, i.e. the lumen shaft line parallel of the axis of said rotating shaft and valve body has a suitable distance between two axial lines.
The described novel exhaust brake valve of the utility model is when braking; The valve of exhaust braking valve kills engine; Engine back pressure is increased to certain numerical value, thus produce certain running torque because the pressure that bear the valve block top and the bottom is different this moment, thus open the valve block of exhaust braking valve; After two kinds of moments reach balance; Back pressure can be stabilized on the suitable numerical value impaired to reduce the too high caused motor of back pressure always, prolongs the working life of motor, and the kinetic energy that can also more effectively utilize motor to absorb automobile simultaneously realizes continuing braking.
The eccentric body of the novel exhaust brake valve of the utility model is the processing technology of axle now, and the off-centre of existing technology is to add at valve body to embody man-hour, and its valve block will guarantee eccentric consistently with valve body adding man-hour, not so will cause and can't close.The utility model adopts rotating shaft and the eccentric design of valve body compared with prior art to guarantee throw of eccentric more easily, and is easy to production and processing, effectively reduces production costs and avoids the too high defective that possibly cause that motor is impaired of back pressure simultaneously, has good effect.
