Description

Band flow controls shutoff valve clutch slave cylinder
Technical field
The present invention relates to automobile clutch technical field, and in particular to a kind of band flow controls shutoff valve clutch slave cylinder.
Background technology
Clutch slave cylinder is a part of car transmissions.Power train is connected by it with engine.From Clutch wheel cylinder is, when stepping on clutch pedal, fluid in clutch general pump and pipeline is pressurized by push rod, pressure rise, in oil pressure Effect is lower to depart from minute wheel by clutch slave cylinder disengaging yoke by clutch compressing disc and piece, starts gearshift, releases the clutch pedal Clutch slave cylinder is stopped.Clutch slave cylinder is for cutting off and realizing the power transmission to power train, to ensure in starting When by reasonable match system smoothly engage, enable automobile gentle start;It is in gear shift that reasonable match is rapid It is completely separated, during the impact for Liu for reducing speed changer middle gear, whole transmission system can be protected by slipping of clutch, zero is prevented Part is damaged because of overload.
When automobile is tightly braked, if the cushioning effect without clutch, because of engine and the connection of power train rigid phase, Rotating speed strives that sharp fall is low, and all movement parts will produce very big moment of inertia, and its numerical value may substantially exceed engine work When send ground peak torque, then cause power train to overload, to cause parts to damage.There is clutch to rest against clutch Issuable relative slip, eliminates this dangerous between active part and secondary part.Therefore, the another function of clutch is The peak torque that limitation power train is born, prevents it from overloading.
Existing clutch also Shortcomings:Slave unit rotator inertia is big when half-clutch, and clutch abrasion is big, cause from Clutch burden is big;When releasing braking oil return, fluid quick backflow, gear impact is big during gear shift, is easily damaged, service life is short.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of reasonable in design, compact conformation, Slave unit rotator inertia is small, and gear impacts when mitigating gear shift, it is to avoid increase clutch burden, improves the band stream of life of clutch Amount control shutoff valve clutch slave cylinder.
To achieve the above object, the invention provides following technical scheme:A kind of band flow controls the valve clutch point that dams Pump, including clutch slave cylinder body, the clutch slave cylinder body include cylinder body and the adjustment seat being wholely set with cylinder body, described It is horizontally arranged with the first oil inlet passage in the middle part of adjustment seat, the first oil inlet passage right-hand member is provided with inlet connector, described the One oil inlet passage left end is provided with glove cavity, and the second oil-feed is vertically arranged between the glove cavity and the inner chamber of the cylinder body Be horizontally arranged with flow control shutoff valve in passage, the glove cavity, the cross central line of flow control shutoff valve with The cross central line of first oil inlet passage is overlapped, and the adjustment seat offers adjustment hole positioned at glove cavity left position, Plug detachably is provided with the adjustment hole, the adjustment seat offers connection positioned at the second oil inlet passage position directly above Hole, the connecting hole threaded upper ends are connected with holding screw.
By using above-mentioned technical proposal, flow control shutoff valve sets reasonable, compact conformation, slave unit when half-clutch Rotator inertia is small, and clutch abrasion is few so that clutch burden is small;When releasing braking oil return, fluid quick backflow is effectively prevented, Gear impact is small during gear shift, it is not easy to damage, service life is long.
The present invention is further arranged to:The flow control shutoff valve includes valve body, valve seat, back-moving spring, steel ball, valve Lid, filtering plug and the first sealing ring, the valve body are provided with body cavity, and the body cavity left end installs valve seat, and valve seat is right End face integral middle is provided with a nose bar, and the back-moving spring is socketed on nose bar, and the body cavity right-hand member installs bonnet, Bonnet inner chamber is provided with the bonnet, bonnet inner chamber right-hand member installs filtering plug, the opening alignment described first of filtering plug The left port of oil inlet passage, bonnet inner chamber left end is provided with bonnet main oil-hole, and the bonnet main oil-hole left end installs steel ball, and steel Ball is connected with back-moving spring right-hand member, and the bonnet upper end is provided with the secondary oilhole of bonnet, and the diameter of the secondary oilhole of the bonnet is less than valve The diameter of lid main oil-hole.By this setting, filtering plug can prevent well brake fluid impurity in existing fluid reservoir enter from Clutch, improves life of clutch;Steel ball can play cushioning effect with spring, and back-moving spring pushes down steel when half-clutch such as when oil pressure is not enough Ball is not opened bonnet main oil-hole, and oil can only be passed through by the secondary oilhole of bonnet on valve seat, and driven position rotator inertia is small, can reduce Clutch abrasion, it is to avoid increase clutch burden;When releasing braking oil return, oil can only pass through by the aperture on valve seat, prevent Gear impacts when quick backflow mitigates gear shift.
The present invention is further arranged to:Annular is provided with bonnet groove, the bonnet groove on the bonnet outer surface The first sealing ring is inside socketed with, first sealing ring is tightly connected with glove cavity inner wall face.Pass through this setting, valve cover structure More reasonable, good seal performance is set.
The present invention is further arranged to:The plug groove of annular, the plug groove inner sleeve are provided with the plug The second sealing ring is connected to, second sealing ring is tightly connected with adjustment hole internal face.By this setting, stopper structure more adduction Reason, good seal performance.
The present invention is further arranged to:The adjustment hole left end, which is provided with the stopper slot of annular, the stopper slot, pacifies Equipped with hole elastic spring.By this setting, plug is fixed relatively reliable.
