Description
[technical field]
The utility model relates to the vehicle transmission field, relates in particular to the clutch booster assembly of hydraulic clutch operating mechanism.
[background technique]
Automobile clutch is installed between motor and the speed changer, is used for separating or engages front and back power contact between the two.Can make the automobile balance starting; Can interrupt power, cooperate gear shift to power train; Can prevent the power train overload.It is indispensable vitals in the automobile.
Automobile clutch has friction clutcch, fluid clutch, magnetic clutch etc. several.Fluid clutch is by the working solution transmitting torque, and shell and pump impeller are connected as a single entity, and are driving links; Turbine is relative with pump impeller, is driven member.When the pump impeller rotating speed was low, turbine can not be driven, and is in separated state between driving link and the driven member; Along with the raising of pump impeller rotating speed, turbine is driven, and is in jointing state between driving link and the driven member.Magnetic clutch comes solenoidoperated cluthes by the power on/off of coil joint with separate.As initiatively and between the driven member placing magnetic, then can strengthen engaging force between the two, such clutch is called magnetic formula magnetic clutch.Friction clutcch is divided into two kinds of wet type and dry types again.At present, the most clutches that match with manual transmission are the dry type friction clutcch, and by the number of its driven disc, it is several to be divided into single-deck formula, double plate and multi-disc type etc. again.Wet friction formula clutch is generally multi-disc type, is immersed in the oil so that heat radiation.
Friction plate clutch is made up of active part, secondary part, hold down gag and operating mechanism four parts.Active part comprises parts compositions such as flywheel, clutch cover, platen.This part and engine crankshaft connect together.Clutch cover is connected by bolt with flywheel, leans on 3-4 driver blade transmitting torque between platen and the clutch cover.Secondary part is made up of monolithic, biplate or multi-disc driven disc, and it transmits active part by friction power is passed to the input shaft of speed changer.Driven disc is by the driven disc body, and three substantial sections of friction plate and clutch plate hub are formed.For fear of the resonance of sense of rotation, relax the impulsive load that power train is subjected to, most of automobiles all on the driven disc of clutch attaching torsion vibration absorber is arranged.Hold-down mechanism mainly is made up of helical spring or diaphragm spring, rotates with active part, and it is a support with the clutch cover, and platen is pressed to flywheel, thereby the driven disc that will be between flywheel and platen compresses.Operating mechanism be the driver so as to making clutch separation, then make it again mildly to engage one the cover mechanism.Be the separating mechanism of forming by parts such as the separator levers that is arranged in clutch housing (at diaphragm spring clutch, diaphragm spring held concurrently the effect of separator levers), release bearing, release sleeve, withdrawal fork, return springs and be positioned at the outer clutch pedal of clutch housing and compositions such as driving mechanism, servomechanism.
Clutch operation mainly comprises mechanical rod member formula, mechanical cable type and hydraulic type, and mechanical rod member formula changes the free travel of pedal by the regulating tie bar control fork.Precession then free travel reduces; Screwing out then, free travel increases.Artis is many in the machinery rod member formula transmission device, so frictional loss is big.The distortion of vehicle body and vehicle frame can influence its work.When clutch needs remote operation, the difficult leverage of rationally arranging.The machinery cable type is adjusted the free travel of clutch pedal by the adjustment nut on rolling motor next door.Machinery cable type drive mechanism is simple, and the device flexible arrangement is not subjected to the influence of vehicle body and vehicle frame distortion, but the force rate of transmitting is less.
Free play of clutch is made of two gaps in the hydraulic type: one is the gap between master cylinder piston and the push rod; Another is the gap between release bearing and the separator levers.It is little that the hydraulic clutch operating mechanism has surface friction drag, and the transmission efficiency height engages advantages such as smooth-going.It is relatively simple for structure, is convenient to arrange, is not subjected to the influence of the distortion of vehicle body and vehicle frame, is a kind of manipulation form of commonplace employing.
In order to alleviate driver's labor intensity, guarantee traffic safety, at present, especially on heavy-duty car, generally using clutch booster on the automobile.Clutch booster is arranged in the hydraulic control mechanism, with Pneumatic braking system and the shared cover compression air source of other pneumatic equipments.When let slip the clutch, by air pressure assisted, increase the power that acts on the separation yoke, clutch separation power is increased, alleviate driver pedal power.
Wearing piece on the clutch booster is easy to wearing and tearing, just needs after wearing piece may wear to a certain degree to change.The abrasion condition that will check wearing piece at present is cumbersome, adjust the booster shift fork, inconvenient operation, and observe the also bigger error of existence, and there is not unified standard, the replacing of wearing piece is often untimely.Simultaneously, adopt between existing fuel inlet fitting and the flexible pipe to be threaded, need rotate a lot of circles during connection, cumbersome, and must be screwed into very tight, otherwise, may produce leakage of oil.
So, how the structure of clutch booster is reasonably improved, make people can observe the abrasion condition of wearing piece easily, so that in time change, become the important topic of those skilled in the art's research.
