Abstract
The invention provides an AMT clutch actuating mechanism which comprises a clutch pedal, a first clutch cylinder and a clutch. The clutch pedal controls disengaging and engaging of the clutch through the first clutch cylinder. The AMT clutch actuating mechanism further comprises a motor, a transmission mechanism, a second clutch cylinder and a three-way valve, the three-way valve is respectively connected with the clutch, a first hand control valve and a second hand control valve, the first hand control valve is connected with the first clutch cylinder, the motor acts on the second clutch cylinder through the transmission mechanism, and the second hand control valve is connected with the other end of the second clutch cylinder. The phenomenon that when the AMT clutch actuating mechanism breaks down, operators have to wait on site is avoided, the AMT clutch actuating mechanism can be used for goods vans and mining vehicles, the attendance rate is improved, and traffic accident risks caused when the vehicles are parked in the middle of a road are reduced.
Description
Technical field
The present invention relates to field of automobile, refer to especially a kind of AMT clutch actuator.
Background technique
Electrical control automatic manual transmission case Automated Mechanical Transmission, is called for short AMT; AMT improves on traditional hand gear type speed changer basis.Manual transmission (MT) is stirred speed change lever with hand could change the gear engagement position in speed changer, changes velocity ratio, thereby reaches the object of speed change, while stepping on clutch, can dial to obtain moving speed change lever.
Existing AMT clutch actuator mainly contains two classes: all electric and electrolyte type.It is to only have braking pedal and accelerator pedal that the vehicle of loading AMT has a common feature, there is no clutch pedal.When existing clutch actuator breaks down, driver can only wait for rescue in original place; And only have professional maintenance man just can keep in repair.
The structural principle of all electric clutch actuator is: driven by motor worm and gear, and worm gear rotarily drives zip, and zip pulls the rotation of clutch rocking arm, thereby realizes separation and the combination of clutch.Zip easily weares and teares, fracture failure.
The structural principle of electrolyte type clutch actuator is: the oil pressure providing by gear pump enters driving clutch element in clutch valve body and realizes clutch self shifter.Clutch actuator is hydraulic system, and complex structure, seal request are high, easily occur oil leakage phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of AMT clutch actuator, to solve existing clutch actuator rapid wear or complex structure and other problems, and when breaking down, can not switch to the problem of MT pattern.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of AMT clutch actuator, comprise clutch pedal, pump clutch one and clutch, described clutch pedal is by separation and the combination of pump clutch one solenoidoperated cluthes, also comprise motor, driving mechanism, pump clutch two and three-way valve, described three-way valve connects respectively clutch, hand control valve one and hand control valve two, described hand control valve one connects pump clutch one, described motor acts on pump clutch two by driving mechanism, described hand control valve two connects the other end of described pump clutch two.
Wherein, described driving mechanism comprises the worm screw being connected with motor, the worm gear being connected with worm screw, the output unit being connected with worm gear.
Wherein, described output unit is gear & rack structure.
Wherein, described output unit is screw-nut structure.
The beneficial effect of technique scheme of the present invention is as follows:
When AMT clutch actuator of the present invention breaks down, driver can change the raw mode of MT into by service manual, and arrival 4S point that can be safe goes for professional workforce and keeps in repair AMT clutch actuator; For requiring the mine car that the rate of attendance is very high, the clutch actuator of this patent is housed, when breaking down, then driver only need disassemble clutch actuator by the operation of aforesaid operations step, and placement is got up, just can continue to turn out for work, so both improve the rate of attendance; The maintenance of convenient for maintaining personnel to AMT clutch actuator again.

Embodiment
For making the technical problem to be solved in the present invention, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to existing clutch actuator rapid wear or complex structure and other problems, and when breaking down, can not switch to the problem of MT pattern, a kind of AMT clutch actuator is provided.
As shown in Figure 1, embodiments of the invention provide a kind of AMT clutch actuator, comprise clutch pedal 5, pump clutch 1 and clutch 8, and described clutch pedal 5 is by separation and the combination of pump clutch one 6 solenoidoperated cluthes 8; Also comprise motor 2, driving mechanism, pump clutch 2 11 and three-way valve 9, described three-way valve 9 connects respectively clutch 8, hand control valve 1 and hand control valve 2 10, described hand control valve 1 connects pump clutch 1, described motor 2 acts on pump clutch 2 11 by driving mechanism, and described hand control valve 2 10 connects the other end of described pump clutch 2 11.
Described driving mechanism comprises the worm screw 1 being connected with motor 2, the worm gear 3 being connected with worm screw 1, the gear & rack structure being connected with worm gear 3 or screw-nut structure 4.
The working procedure of clutch actuator of the present invention is as follows:
Utilize motor 2 to drive worm screw 1 and worm gears 3, worm gear 3 driven gear rack structures or screw-nut structure 4 promote combination that pump clutch 2 11 moves to realize clutch with separated.
During normal use AMT pattern, hand control valve 1 cuts out, and hand control valve 2 10 is opened, simultaneously that clutch pedal 5 is fixing, make driver cannot step on clutch pedal 5, control unit is to motor 2 signals, and motor 2 rotations, drive worm screw 1 and worm gear 3 rotations, thereby driven gear rack structure or screw-nut structure 4 motions, rotatablely moving of motor 2 converted to the straight line motion of tooth bar or leading screw, and then promote pump clutch 2 11 and do fore and aft motion, finally realize separation and the combination of clutch 8.
When AMT clutch actuator breaks down, only hand control valve 1 need be opened, hand control valve 2 10 cuts out, and clutch pedal 5 is removed and is fixed simultaneously, can revert to the MT pattern of former car.
When AMT clutch actuator of the present invention breaks down, driver can change the raw mode of MT into by service manual, and arrival 4S point that can be safe goes for professional workforce and keeps in repair AMT clutch actuator; For requiring the mine car that the rate of attendance is very high, the clutch actuator of this patent is housed, when breaking down, then driver only need disassemble clutch actuator by the operation of aforesaid operations step, and placement is got up, just can continue to turn out for work, so both improve the rate of attendance; The maintenance of convenient for maintaining personnel to AMT clutch actuator again.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
