Description
Technical field
The utility model relates to a kind of auto parts, especially a kind of clutch final controlling element of automatic transmission.
Background technique
At present; Vehicle automatic transmission has become one of important directions of automotive engineering development; And AMT automatic transmission and other automatic transmission relatively have the following advantages: mechanical transmission, transmission efficiency is high, cost is low, be easy to manufacturing, is mainly used in motorbus and heavy truck.
External is adopted on sensor and inlet and outlet road in traditional clutch final controlling element assembly; This just must increase the carrier part and realize; External parts must take the certain installing space of car body when mounted, and external device receives the influence of external environment easily, and are fragile.
Summary of the invention
The purpose of the utility model is: a kind of clutch final controlling element of automatic transmission is provided, and it has reduced the installation occupation space, has avoided external device to receive the influence of external environment and damages, to overcome the deficiency of existing technology.
The utility model is achieved in that the clutch final controlling element of automatic transmission; Comprise clutch final controlling element cylinder assembly; End at clutch final controlling element cylinder assembly is connected with valve body down; End at following valve body is connected with upper valve body, is being provided with air inlet solenoid valve, exhaust solenoid valve and pneumatic filter in the valve body down, and the suction port of pneumatic filter is in the valve body outside down; Be provided with displacement transducer in the valve body down, the front end of displacement transducer is in the clutch final controlling element cylinder assembly, in the valve body, in displacement transducer, is provided with the exhaust passage under its underpart is in, the internal communication of the exhaust passage of displacement transducer and following valve body.
Between the link position of following valve body and upper valve body, be provided with sealing gasket.
Be provided with surface-mounted integrated circuit in the valve body down, surface-mounted integrated circuit is connected with air inlet solenoid valve, exhaust solenoid valve and displacement transducer.Integrated being installed in down in the valve body of circuit board of control air inlet solenoid valve, exhaust solenoid valve and displacement transducer can further be simplified structure, and can increase the reliability and the working life of surface-mounted integrated circuit.
Owing to adopted technique scheme, compared with prior art, the utility model adopts valve body structure with the housing of equipment; Valve inner is connected by air flue; Make clutch final controlling element assembling better, and the external valve piece of tradition, tracheae, sensor, solenoid valve and flex circuit control panel integrated be positioned in the valve body, realize that part integral body is built-in; This is very typical mechanical integrated morphology; Integrated morphology can be saved a large amount of installing spaces, and such design had both increased product reliability and working life, reduces the installing space of clutch final controlling element assembly again.The utility model is simple in structure, and is easy to make, with low cost, and using effect is good.

Accompanying drawing 2 is the structural representation of the following valve body of the utility model.
Accompanying drawing 3 is the sectional view of accompanying drawing 1.
Embodiment
The embodiment of the utility model: the structure of the clutch final controlling element of automatic transmission is as shown in Figure 1; Comprise clutch final controlling element cylinder assembly 1; End at clutch final controlling element cylinder assembly 1 is connected with following valve body 2 through screw; End at following valve body 2 is connected with upper valve body 3, between the link position of following valve body 2 and upper valve body 3, is provided with sealing gasket 8, and following valve body 2 is formed valve bodies with upper valve body 3; Be provided with air inlet solenoid valve 4, exhaust solenoid valve 5 and pneumatic filter 6 in the valve body 2 down, the suction port of pneumatic filter 6 is in valve body 2 outsides down; Be provided with displacement transducer 7 in the valve body 2 down; The front end of displacement transducer 7 is in the clutch final controlling element cylinder assembly 1; Under being in, its underpart in the valve body 2, in displacement transducer 7, is provided with exhaust passage 9, the exhaust passage 9 of displacement transducer 7 and the internal communication of following valve body 2; Be provided with surface-mounted integrated circuit 10 in the valve body 2 down, surface-mounted integrated circuit 10 is connected with air inlet solenoid valve 4, exhaust solenoid valve 5 and displacement transducer 7.
In use; High-pressure air gets into valve body through pneumatic filter 6; When vehicle needed clutch to realize separated state, the air inlet solenoid valve 4 that ECU TCU installs on the valve body of clutch final controlling element sent power on signal, after 4 energisings of air inlet solenoid valve with air inlet open; This high-pressure air gets in the clutch final controlling element cylinder assembly 1 through the air flue of valve inner; Promote piston and outwards move, thereby the disengaging yoke push rod that promotion is connected with piston makes the clutch that is connected with the disengaging yoke push rod realize separated state; The displacement transducer 7 that is installed in down in the valve body 2 is judged clutch actuator motions position through the rodmeter inductance that impression is installed on the piston; ECU TCU is after the air inlet solenoid valve of installing on the valve body 2 under the clutch final controlling element 4 sends power-off signal; Air inlet solenoid valve 4 will cut out the high-pressure air of pneumatic filter 6 imports; Simultaneously exhaust solenoid valve 5 is sent power on signal; Exhaust solenoid valve 5 is opened relief opening after receiving signal; High-pressure air in the clutch final controlling element cylinder assembly 1 is communicated with the exhaust passage 9 on the displacement transducer 7, state piston returns to motion under automobile clutch separates the effect of back elastic force before, the cylinder inner volume reduce the back high-pressure air through under exhaust solenoid valve 5 valve openings entering clutch final controlling element valve body inside on the valve body 2; The exhaust passage 9 that is connected with piston through displacement transducer 7 directly enters atmosphere, and clutch is accomplished bonding state.
