Description
Technical field
The present invention relates to a kind of clutch actuating mechanism of automatic mechanical speed variator.
Background technique
What prior mechanical automatic transmission clutch actuator generally adopted is Electric Machine Control and hydraulic control dual mode, wherein Electric Machine Control mainly is to adopt motor one screw-nut structure, rotating band movable wire thick stick by motor rotates, the rotation of leading screw drive nut again moves reciprocatingly, thereby realizes the separation and the combination of clutch; And hydraulic control mainly is to adopt motor one brace and connecting rod framework, by moving of motor driving connecting rod, drives the to-and-fro motion of hydraulic cylinder piston, thereby realizes the separation and the combination of clutch.Though this dual mode can both make clutch separation and combination, the kind of drive that this dual mode adopted is more complicated all, and its component are complicated, difficulty of processing is big, simultaneously, because kind of drive more complicated causes steady weak effect in the transmission process.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, stable transmission clutch actuating mechanism of automatic mechanical speed variator.
The objective of the invention is to realize by such technological scheme, it includes clutch drive apparatus and clutch master cylinder assembly, the clutch gear that described clutch drive apparatus includes clutch motor, clutch motor worm screw, clutch motor worm gear and meshes with the clutch motor worm gear; Described clutch master cylinder assembly includes master cylinder piston, is provided with clutch tooth bar assembly in clutch housing, and clutch drive apparatus is connected with the clutch master cylinder assembly by clutch tooth bar assembly.
Change the transverse movement of tooth bar in order to make rotatablely moving of clutch drive apparatus, described clutch tooth bar assembly includes the clutch tooth bar of band clutch tooth bar push rod, the spring guide sleeve, clutch tooth bar block and clutch master cylinder preloading spring, described clutch tooth bar push rod is connected with the clutch master cylinder assembly, described clutch tooth bar is arranged in the clutch housing by linear bearing, described spring guide sleeve, clutch master cylinder preloading spring and clutch tooth bar block all are successively set on the right-hand member of clutch tooth bar, and described spring guide sleeve is spacing by clutch housing.
For with the transmission of power of clutch drive apparatus to clutch tooth bar assembly, clutch drive apparatus is can be to be connected like this with clutch tooth bar assembly like this: described clutch gear and clutch tooth bar mesh.
In order to give clutch master cylinder with transmission of power, described clutch tooth bar push rod can be connected like this with the clutch master cylinder assembly: clutch tooth bar push rod is connected with master cylinder piston.
For operating rate and the displacement that accurately obtains the clutch tooth bar, realize terminal control, clutch housing is provided with angle transducer, and described angle transducer is connected with clutch shaft.
The present invention is work like this: drive the clutch motor worm screw after the clutch motor work and rotate, the clutch motor worm screw of rotating drives the clutch motor worm gear and rotates, the clutch motor worm gear drives of the rotating clutch gear rotation that is meshed of internal tooth with it, clutch gear drives clutch tooth bar move left and right, because clutch tooth bar push rod is connected with master cylinder piston, so just having driven master cylinder piston advances or retreats, and then promote hydraulic oil and enter the hydraulic pressure release bearing, realize separating and combination of clutch and transmission input shaft.
Owing to adopted technique scheme, the present invention to have following advantage:
1. owing to adopted clutch tooth bar assembly structure, the validity height that makes transmission, stable drive;
2. because clutch teeth strip adoption linear bearing is arranged in the clutch housing, be convenient to the fast moving of tooth bar, be beneficial to the separation of hydraulic pressure release bearing;
3. owing to adopt the clutch master cylinder preloading spring, do the travelling speed that to accelerate the clutch tooth bar like this, accelerate the separating rate of hydraulic pressure release bearing;
4. adopt angle transducer to be connected, can accurately gather the operating rate of clutch tooth bar and displacement more, reached and realized the purpose that end is controlled with clutch shaft.
