Abstract
The invention relates to a novel clutch actuator of an automatic gearbox, which is characterized in that a protective valve is a bi-pass one-way valve and is provided with two air inlets and an air outlet, wherein one of the air inlets of the protective valve is connected with a manual operation control valve, while the other air inlet is connected with an automatic operation control valve; the air outlet of the protective valve is connected with a cylinder, and only one air passage is communicated when two air passages are in work; and the manual operation control valve is a hydraulic valve.The novel clutch actuator of the automatic gearbox realizes the operations of releasing and connecting an electrically controlled pneumatic clutch, and the structure of the novel clutch actuator of the automatic gearbox not only meets the control requirements but also the execution of the clutch by manual control and automatic control, thereby achieving the driving function of integrating the manual control and the automatic control, saving the cost of reopening a mould, only needing to produce part of components, saving the cost, and having great economic benefits and social benefits.
Description
Technical field:
The present invention relates to a kind of novel clutch actuator of automatic gearbox, be applied to truck automatic transmission field, it can carry out clutch control valve in automatic shift system instruction separates clutch and the operation of combination, and can realize manually control and the operation under the control automatically respectively.
Background technique:
System (AMT) lining at the electric-controlled mechanical gearbox, the separation that needs the computer solenoidoperated cluthes with engage, in pneumatic actuator system, the break-make of controlling pressurized gas by solenoid valve of computer control realizes the promotion to the final controlling element cylinder, thereby realizes the joint of clutch and the operation that separates.And in the automatic speed-changing system of auto-manual; final controlling element must adapt to the action under automatic control and two kinds of controls of manual control; this just need the final controlling element of clutch can satisfy simultaneously manual control and automatically under the control to the operation of clutch, and the relatively independent protection mutually again of gas circuit under two control modes.
Summary of the invention:
The object of the present invention is to provide a kind of novel clutch actuator of automatic gearbox, mainly solve in automatically controlled auto-manual mechanical automatic gearbox, carry out clutch separation and oncoming clutch final controlling element; Can require clutch is operated according to control under control and the manual control automatically.
Technological scheme of the present invention is achieved in that a kind of novel clutch actuator of automatic gearbox, it is characterized in that: Protective valve is the bilateral one-way valve, air outlet of two suction ports is arranged, wherein Protective valve suction port links to each other with the manually-operable control valve, and another suction port links to each other with automatic operation control valve; The air outlet of Protective valve links to each other with cylinder, has only a gas circuit to communicate during two gas circuit work; The manually-operable control valve is a hydraulic valve.
Good effect of the present invention is an indispensable part in the ecp mechanical automatic gearbox system, electropneumatic clutch separation and the operation that engages have been realized, thereby realized the gearshift of gearbox, its structure has not only satisfied the control requirement, but also realized manual control and automatically during control to the execution of clutch, thereby realized the driving function of auto-manual; On the structure on the basis of the clutch power-assisted pump of original manual control, improve by functional requirement, make that so most of component of former boost pump can be general, saved the expense of die sinking tool again, only need produce part again, save cost, had great economic benefit and social benefit.
Description of drawings:
Fig. 1 is a structural principle sketch of the present invention;
Fig. 2 is a structured flowchart of the present invention;
Embodiment:
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1, a kind of novel clutch actuator of automatic gearbox, it is characterized in that: Protective valve 1 is the bilateral one-way valve, 2,3 one air outlets 4 of two suction ports are arranged, wherein Protective valve 1 suction port 2 links to each other with manually-operable control valve 5, and another suction port 3 links to each other with automatic operation control valve 6; The air outlet 4 of Protective valve 1 links to each other with cylinder 7, has only a gas circuit to communicate during two gas circuit work; Manually-operable control valve 5 is a hydraulic valve.
Whenever can only keep a gas circuit to pass through; under the manual drive pattern; driver's pedal makes hydraulic oil enter the right chamber that final controlling element arrives manually-operable control valve 5 from filler opening; when pressure reaches cracking pressure; the control valve piston is moved to the left; other just can pass through this control valve high pressure; enter Protective valve 1; when the piston of Protective valve 1 moves up; manually the pressurized gas of control have just entered and have promoted cylinder piston in the cylinder 7, and the suction port 2 that the piston of while Protective valve 1 also will be controlled is automatically closed.When the driver lifts pedal, hydraulic fluid pressure descends, and manually-operable control valve 5 has been closed air inlet, and the high pressure air in the cylinder 7 are discharged through relief openings.
When the pedal attonity; automatically control; autocontrol valve 6 is opened in computer (TCU) control; pressurized gas advanced autocontrol valve and entered Protective valve 1; Protective valve 1 piston moves down; close manual control air inlet loop and connect automatic control air inlet loop simultaneously, realize the control of computer (TCU) clutch.
As shown in Figure 2, the effect of Protective valve is that what to guarantee to enter cylinder can only be manual or automatic one tunnel high pressure air, and when promptly a gas circuit was connected, another gas circuit must be closed.
Claims (2)
