Description
Technical field
The present invention relates to a kind of complemental brake system of motor car engine, particularly a kind of manipulating cylinder of automobile engine to exhaust brake valve with internal respiration function.
Background technique
The motor car engine braking system is one of device always of present vehicle safety travel.When vehicle need slow down particularly in the mountain area or city bus when needing frequent braking, if frequently use service brake, will cause wheel drag overheated and make braking function decline, as untimely taking emergency measures (cooling of stopping), even can cause braking total failure and the vehicle condition of causing danger.So adopt nothing decline property auxiliary braking system to be very important at this situation.Use complemental brake system can strengthen the vehicle braked performance, do not need to use or use break (traditional friction brake) just vehicle can be controlled in certain safety speed scope less, the prevention car brakeing is malfunctioning, guarantee traffic safety, particularly strengthen the Security of heavy-duty vehicle lower long slope.Use retarder can reduce the frequency of utilization of main Service Brake (friction brake) significantly simultaneously, thereby reduce the wearing and tearing of foundation brakes braking hub and friction plate, improve its working life, prolong the service cycle of foundation brakes simultaneously, reduce maintenance cost, improve the Security and the travelling comfort of driving, reduce driver's fatigue, increase work efficiency.
In the auxiliary brake device for automobile that uses at present, exhaust brake is simple in structure because of it, and reliable performance is handled easily, and is easy for installation, and it also got widely as a kind of complemental brake system and uses.Exhaust brake is that a dishful of valve and rotating mechanism are installed in the engine exhaust pipeline, increases the exhaust stroke resistance by closing this dish valve, and the exhaust that utilizes motor is as auxiliary braking.Usually exhaust braking valve in use manipulating cylinder enter rainwater and dust easily, can cause that like this sealing part abrasion, the spring of cylinder get rusty etc. influences the working life and the braking effect of exhaust brake valve assembly.
Summary of the invention
The manipulating cylinder that the purpose of this invention is to provide a kind of automobile engine to exhaust brake valve prevents when can be implemented in work that rainwater and dust from entering cylinder body, can improve the effect of engine exhaust and brake, and prolongs the working life of exhaust brake valve assembly.This apparatus structure is reasonable, and the reliability height is suitable for the complemental brake system of motor car engine.
The invention provides a kind of manipulating cylinder of automobile engine to exhaust brake valve, comprise cylinder body 11, piston 12, return spring 15, push rod 7 and cylinder head 9, piston 12 connects push rod 7, piston 12 is divided into mutual disconnected A chamber and C chamber with cylinder body 11, the C chamber is provided with suction port, offer the channel B that is connected A chamber and C chamber in push rod 7 and the piston 12, be provided with the one-way valve 16 of band valve spring 13 between top, C chamber and the channel B below, be provided with spring bushing 10, outer dust ring 8 and interior dust ring 14 above the A chamber.
The material of described outer dust ring 8 and interior dust ring 14 is preferably high temperature resistant and high-abrasive material.
The present invention also provides a kind of automobile engine to exhaust brake valve, comprises valve body 1, valve block 6, rotating shaft 2, dunnage 4, rocking arm 3, push rod 7 and manipulating cylinder 5, and described manipulation cylinder 5 adopts aforementioned manipulating cylinder.
According to device of the present invention, do not produce gas exchange with the external world, avoided entering of foreign matter such as dust in the ambient atmosphere, and simple and practical, working stability is strong, can be widely used in the engine exhaust and brake device.
Description of drawings
Fig. 1 is the side view of automobile engine to exhaust brake valve of the present invention, and Fig. 2 is the plan view of automobile engine to exhaust brake valve of the present invention, and Fig. 3 is the sectional view of manipulating cylinder of the present invention, wherein:
1, valve body, 2, rotating shaft, 3, rocking arm, 4, dunnage, 5, manipulating cylinder, 6, valve block, 7, push rod, 8, outer dust ring, 9, cylinder head, 10, spring bushing, 11, cylinder body, 12, piston, 13, valve spring, 14, interior dust ring, 15, return spring, 16, one-way valve.
Embodiment
The present invention will be described below in conjunction with embodiment and accompanying drawing:
The schematic representation of the manipulating cylinder of the automobile engine to exhaust brake valve shown in Figure of description, it comprises cylinder body 11, piston 12, return spring 15, push rod 7 and cylinder head 9, piston 12 connects push rod 7, piston 12 is divided into mutual disconnected A chamber and C chamber with cylinder body 11, the C chamber is provided with suction port, offer the channel B that is connected A chamber and C chamber in push rod 7 and the piston 12, be provided with the one-way valve 16 of band valve spring 13 between top, C chamber and the channel B below, top, A chamber is provided with spring bushing 10, outer dust ring 8 and interior dust ring 14.
The material of described outer dust ring 8 and interior dust ring 14 is preferably high temperature resistant and high-abrasive material.
The schematic representation of the automobile engine to exhaust brake valve shown in Figure of description, it comprises valve body 1, valve block 6, rotating shaft 2, dunnage 4, rocking arm 3, push rod 7 and manipulating cylinder 5, described manipulation cylinder 5 adopts aforementioned manipulating cylinder.
When the suction port air inlet of C chamber, one-way valve 16 is closed, and promotes piston 12 compression retracteding position springs 15, and this moment, the air pressure in A chamber was discharged to outer dust ring 8 from interior dust ring 14 along push rod 7.During C chamber inlet close, push rod 7 is by the effect of return spring 15, piston 12 beginning returns, and one-way valve 16 is pushed open by valve spring 13, and the air pressure in A chamber is discharged to the C chamber to one-way valve 16 from the channel B that connects A chamber and C chamber again.
When using the conventional manipulating cylinder of prior art, rainwater enters cylinder can influence working life with the return spring corrosion, and dust enters cylinder and will mix with lubricant oil and cause packed-piston to wear and tear to leak gas.
When using manipulating cylinder of the present invention, outer dust ring and interior dust ring can dual prevention rainwater and dust enter cylinder, the same clean when using in the rear cylinder still with assembling, improve the effect of engine exhaust and brake, and prolonged the working life of exhaust brake valve assembly.
