Abstract
The invention discloses a kind of automatic drive of clutch, including：Pressure-regulating valve, it has air inlet, gas outlet and exhaust outlet, and air inlet is used for input air, and gas outlet is used for compressed gas of the adjustable pressure of output pressure less than the air pressure of air inlet；And wheel cylinder cylinder, it includes push rod, and the shift fork connection of push rod and clutch, the cylinder body of wheel cylinder cylinder is connected with gas outlet, and pressure-regulating valve adjusts the air pressure in wheel cylinder cylinder by the pressure of dynamic regulation gas outlet.The automatic drive guarantee to realize clutch quickly separate, quickly combine while, can also realize that the semi-linkage of clutch is combined.
Description
Technical field
The present invention relates to clutch field, more particularly to a kind of automatic drive of clutch.
Background technology
Existing clutch drive apparatus is bivalve controller, according to entire car controller (HCU) instruction, controls A, B two
The open and close of individual magnetic valve, and then the into or out clutch power-assisted wheel cylinder cylinder of compressed air is controlled, so as to realize point
Pushing open and return for pump, reaches clutch separation and the purpose combined.
Existing clutch drive apparatus has the disadvantages that：
1st, clutch " semi-linkage " state can not be accurately controlled, only by magnetic valve A and B opening and closing, it is impossible to
The air supply of into or out cylinder is accurately controlled, the pressure of clutch combination or separation process also just can not be accurately controlled
And speed.Clutch is combined, separation process control is improper, is caused vehicle to drive ride comfort and is declined, and the lower starting of high pressure failure is paid no attention to
Think engine easily occur and drawn flame-out phenomenon；
2nd, whole control process hardware is various, and cost is of a relatively high；
3rd, arrangement of mechanism is cumbersome, and trouble point is more and maintenance difficult.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of automatic drive of clutch, guaranteeing to realize that clutch quickly divides
While opening, quickly combine, it can also realize that the semi-linkage of clutch is combined.
To achieve the above object, the invention provides a kind of automatic drive of clutch, including：Pressure-regulating valve,
It has air inlet, gas outlet and exhaust outlet, and air inlet is used for input air, and it is low that gas outlet is used for the adjustable pressure of output pressure
In the compressed gas of the air pressure of air inlet；And wheel cylinder cylinder, it includes push rod, the shift fork connection of push rod and clutch,
The cylinder body of wheel cylinder cylinder is connected with gas outlet, and pressure-regulating valve is adjusted by the pressure of dynamic regulation gas outlet in wheel cylinder cylinder
Air pressure.
Preferably, air inlet and the connection of pressure regulation cleaner.
Compared with prior art, the present invention has the advantages that：Clutch is realized to the control of Pcv valve by program
Quick separating, it is quick combine and semi-linkage function, not only simplified mechanism, and can more accurately control clutch
Separation, combination degree, significantly improve vehicle and drive ride comfort.Simultaneously, it is possible to achieve " semi-linkage " high pressure failure of vehicle
Starting, in vehicle high-voltage unit failure, driver can take contingency mode to move car to roadside or directly open to neighbouring dimension
Factory's maintenance is repaiied, it is not only time saving and energy saving, and safety.
Brief description of the drawings
Fig. 1 is the automatic drive principle schematic of the clutch according to the present invention；
Fig. 2 is the performance diagram of pressure-regulating valve in the automatic drive according to the clutch of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment to the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, being adjusted according to a kind of automatic drive of clutch of the specific embodiment of the invention, including pressure
Valve 1 and wheel cylinder cylinder 2 are saved, wherein pressure-regulating valve 1 has air inlet, gas outlet and exhaust outlet, and air inlet is used for inputting sky
Gas, gas outlet is used for compressed gas of the adjustable pressure of output pressure less than the air pressure of air inlet, and wheel cylinder cylinder 2 includes pushing away
The shift fork connection of bar, push rod and clutch, the cylinder body of wheel cylinder cylinder 2 is connected with gas outlet, and pressure-regulating valve 1 passes through dynamic regulation
The pressure of gas outlet adjusts the air pressure in wheel cylinder cylinder 2.
In such scheme, pressure-regulating valve 1 is also referred to as Pcv valve, is that existing one kind accurately controls gas outlet to press by program
The valve of power, according to the characteristic curve (participation Fig. 2) of the valve, can realize gas outlet pressure by inputting certain dutycycle
Adjustment.According to the characteristic of above-mentioned valve, this programme is applied in the control of clutch, specifically, according to clutch point
From bearing thrust, air pressure size needed for wheel cylinder cylinder is calculated, with reference to Fig. 2 Pcv valve characteristic curve, according to entire car controller 4
(HCU) instruction control Pcv valve dutycycle output, accurately controls it to export air pressure, and then can adjust clutch so as to realize
Air pressure size in aided power separated pump cylinder 2, with indirect control and adjusts separation and the combination degree of clutch so that clutch is combined
Steadily, impact small, improve and drive ride comfort, reduce engine and drawn flame-out probability.
As a kind of preferred embodiment, air inlet and the connection of pressure regulation cleaner.
To sum up, the automatic drive of the clutch of the present embodiment, clutch is realized by program to the control of Pcv valve
Quick separating, quick combination and semi-linkage function, have not only simplified mechanism, and can more accurately control clutch point
From, combination degree, significantly improve vehicle and drive ride comfort.Simultaneously, it is possible to achieve " semi-linkage " high pressure of vehicle fails
Step, in vehicle high-voltage unit failure, driver can take contingency mode to move car to roadside or directly open to neighbouring maintenance
Factory overhauls, not only time saving and energy saving, and safety.
It is foregoing to the present invention specific illustrative embodiment description be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles and its reality of the present invention should
With so that those skilled in the art can realize and using the present invention a variety of exemplaries and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
