Abstract
The invention discloses a clutch actuating mechanism of an AMT (Automated Mechanical Transmission), comprising a motor, a reducing mechanism, an overrun clutch, a clutch pinion, a rack, a sector gear and a sensor, wherein the overrun clutch is arranged between the reducing mechanism and the clutch pinion; the input end of the reducing mechanism is used for transmitting power to the overrun clutch connected with the output end of a reduction box through being connected with the motor; the output end of the overrun clutch is connected with the clutch pinion; the power of the motor is converted into linear motion of the rack through the connection of the clutch pinion and the rack; the rack is connected with a stay cable; and the stay cable is used for pulling a clutch release fork and driving a clutch release bearing to move so as to realize the release of the clutch. According to the clutch actuating mechanism, the high efficiency of the reducing mechanism and the reverse lock-up function of the overrun clutch are used, therefore, the motor power can be fully utilized, and the faster release of the clutch is realized.
Description
Technical field
The present invention relates to the automotive transmission technical field, more particularly, relate to a kind of AMT clutch actuating mechanism.
Background technique
What the employed clutch actuating mechanism of the employed AMT automatic transmission of AMT automatic transmission, especially passenger car commonly used at present adopted mostly is the reducing gear form that oil hydraulic motor adds solenoid valve form or band auto-lock function.But all there are the some shortcomings of self separately in the actuator of these forms: oil hydraulic motor is added the solenoid valve form, its complex structure, high, the poor controllability of cost; As far as the reducing gear form of band auto-lock function, generally not high for satisfying the self-locking requirement transmission efficiency, so just make the automobile clutch disengaging time long partially, reduced shift property.
Self-locking is the condition that clutch actuating mechanism must satisfy; When automobile runs into the red parking idling; Clutch separation; If the clutch actuating mechanism motor loses power supply, the automobile clutch of this moment does not admit of slippage and just prevents the unexpected combination of clutch, so transfer route must have reverse self-locking requirement.Along with the performance requirement of AMT automatic transmission is increasingly high, it is extremely urgent concerning improving shift property under the condition that satisfies economic and safety, to reduce the clutch separation time.
Summary of the invention
In view of this; The invention provides a kind of clutch actuating mechanism of AMT automatic transmission; Through utilization to free wheel device; Solving AMT automatic transmission clutch actuator transmission efficiency problem on the low side effectively, economically, and solve the problem that efficient separation fast that clutch carries out possesses auto-lock function simultaneously.
The basic thought that the present invention solves the problems of the technologies described above is: on the clutch actuating mechanism of AMT automatic transmission, use free wheel device; Motor loses under the condition of power supply feelings when satisfying the automobile clutch separation; Automobile clutch keeps the requirement of not slippage of current location; Shorten the clutch separation time through improving transmission efficiency, effectively solve the contradiction of efficient and self-locking.
For realizing above-mentioned purpose, the present invention provides following technological scheme:
A kind of clutch actuating mechanism of AMT automatic transmission comprises motor, reducing gear, free wheel device, clutch pinion, tooth sector, tooth bar and sensor.Said free wheel device is arranged between reducing gear and the clutch pinion; Be assemblied on the clutch actuating mechanism housing; The outer cylinder of free wheel device is fixed on the clutch actuating mechanism housing and can not does relative motion; The input end of said free wheel device is connected with the reducing gear output terminal, output terminal is connected with clutch pinion; The clutch steamboat cooperates transferring power with tooth bar, and sensor is connected on the tooth sector that meshes with clutch pinion, and sensor meshes the situation of movement of monitoring tooth bar through fan tooth and clutch pinion.The input end of reducing gear is connected with motor.
Said free wheel device is the bidirectional locking free wheel device, and its input end can be given output terminal by positive and negative bi-directional torsion, and output terminal can not be given input end by transmitting torque.
The transmission of power road of the clutch actuating mechanism of this AMT automatic transmission is followed successively by: motor, reducing gear, free wheel device, clutch pinion are to tooth bar.The power-converting that is connected motor through clutch pinion and tooth bar is the straight line motion of tooth bar, and tooth bar is connected with drag-line again, and zip pulling clutch release fork drives the clutch release bearing motion, realizes the separation of clutch.
The reducing gear of the clutch actuating mechanism of this AMT automatic transmission can be used mechanisms such as reduction gears mechanism, worm and gear.
The clutch actuating mechanism of this AMT automatic transmission has utilized the reverse self-locking of free wheel device
, the positive freedom transferring power characteristic, make in exploitation and can consider self-locking performance during reducing gear and improve power transmission efficiency.
If the clutch actuating mechanism of this AMT automatic transmission motor in carrying out clutch disengage process loses power supply, load just automobile clutch keeps not slippage of current location.
Can find out from technique scheme; The present invention is the core that is used for free wheel device; Utilized the latching characteristics of the power reverse transmission of free wheel device; When the design reducing gear, can improve its transmission efficiency to greatest extent, avoid in the design reducing gear, sacrificing transmission efficiency because need satisfy self-locking requirement.High efficiency transmission can make power of motor be fully utilized, and shortens the disengaging time under the certain situation of clutch separation power.
