Specific embodiment
With reference to the accompanying drawings and examples, the present invention is further explained.In the following detailed description, only pass through explanation
Mode describes certain exemplary embodiments of the present invention.Undoubtedly, those of ordinary skill in the art will recognize,
In the case of without departing from the spirit and scope of the present invention, described embodiment can be repaiied with a variety of different modes
Just.Therefore, attached drawing and description are regarded as illustrative in nature, and are not intended to limit the scope of the claims.
As shown in Figure 1 to Figure 3, vacuum servo formula clutch separating mechanism is installed between clutch pedal 1 and clutch 2；Institute
It states clutch pedal 1 and vacuum booster 4 is connected by clutch bracing wire 3, power-assisted push rod is slidably fitted in the vacuum booster 4
48, the clutch bracing wire 3 is sequentially connected the power-assisted push rod 48, the power-assisted push rod 48 and the clutch yoke 21 on clutch 2
Connection；When stepping on the clutch pedal 1, the power-assisted push rod 48 of the vacuum booster 4 is in clutch bracing wire 3 and vacuum servo
The clutch yoke 21 on the clutch 2 is pushed to act under collective effect and then makes clutch separation.
In this way, clutch bracing wire 3,3 rear end of clutch bracing wire connection vacuum booster are on the one hand directly connected to by clutch pedal 1
4, the thrust that vacuum booster 4 generates is acted directly in the clutch yoke 21 of clutch 2, without clutch general pump, clutch pipeline
Parts are waited so as to save cost.Transmission without clutch fluid reduces fluid and transmits loss, improves transmission efficiency.Separately
On the one hand, clutch pipeline is substituted by clutch bracing wire, avoid vehicle frame space limitation caused by clutch pipeline be difficult to what is arranged
Problem makes arrangement more flexible and convenient；Subsequent maintenance maintenance is simpler.Furthermore when clutch pedal acts on, clutch bracing wire with it is true
Empty power-assisted is acted on simultaneously on the power-assisted push rod of clutch booster, realizes clutch power-assisted, is reduced clutch pedal power, is improved
The comfort that clutch manipulates.
Wherein, vacuum booster 4 may be used a variety of concrete structures in the prior art and realize, the basic phase of structural principle
Together.With reference to figure 3, in the present embodiment, the vacuum booster 4 includes housing 41 and is formed in the shell by diaphragm interval
Air chamber 42 and vacuum servo chamber 43 in body 41, the vacuum servo chamber 43 connect vacuum source by vacuum line 7；It is described true
Empty source includes vacuum tank 6, and the vacuum tank 6 vacuum pump 5 subsidiary with engine is connect (with reference to figure 1)；It is set on the housing 41
The vacuum servo valve 45 for being switched off or on the vacuum line 7 is equipped with, vacuum servo valve 45 passes through vacuum interface tube 452 and vacuum
Pipeline 7 connects；The valve push rods 451 (or switch executive mechanism of other forms) of the vacuum servo valve 45 are connected with rocking arm
46, Rocker arm 46 is rotatably mounted in for supporting point in the housing with rocker arm pivot 44, described in 6 one end of Rocker arm 4 stretching
Housing 41 is simultaneously connect with the clutch bracing wire 3；Valve return spring 453 is provided in the vacuum servo valve 45；The power-assisted
