Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through
Bright mode describes certain exemplary embodiments of the utility model.Undoubtedly, those skilled in the art can be with
It recognizes, it, can be with a variety of different modes to described without departing from the spirit and scope of the utility model
Embodiment is modified.Therefore, attached drawing and description are regarded as illustrative in nature, rather than the protection for limiting claim
Range.
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
It pushes the clutch yoke 21 on the clutch 2 to act under collective effect and then makes clutch separation.
In this way, being on the one hand directly connected to clutch bracing wire 3 by clutch pedal 1,3 rear end of clutch bracing wire connects vacuum booster
4, the thrust that vacuum booster 4 generates acts directly in the clutch yoke 21 of clutch 2, without clutch general pump, clutch pipeline
Equal parts are 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, avoids what clutch pipeline caused by the limitation of vehicle frame space was difficult to arrange
Problem keeps 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 acts on the power-assisted push rod of clutch booster simultaneously, realizes clutch power-assisted, reduces clutch pedal power, improve
The comfort that clutch manipulates.
