Embodiment:
Shown in the processing and fabricating by specification accompanying drawing of the heavy duty automobile gear box of tape synchronizer of the present utility model routinely the automobile gearbox processing technology process and get final product.
Working procedure and working principle are as follows:
The structure of two third gear synchronizers and working procedure, shown in figure two, two conical disc that inner conical surface arranged are separately fixed on two intermediate gears and two three-range transmissions, two with matching have the conical ring of male cone (strobilus masculinus) to be connected with two third gear teeth cover with three V-shaped groove locating studs by six dovetail groove lock pins, dovetail groove lock pin and V-shaped groove locating stud space on same circumference distributes, two tops and the conical ring of dovetail groove lock pin are riveted together, the working surface diameter at two ends equates with corresponding pin-and-hole internal diameter on the tooth cover flange, its middle part diameter is then less than the pin-and-hole internal diameter, only the tooth cover can move axially along the dovetail groove lock pin when dovetail groove lock pin and tooth cover pin-and-hole centering, in order to increase trapezoidal lock pin tooth is overlapped axial thrust, on in dovetail groove lock pin middle part and tooth cover, justifying accordingly the pin-and-hole two ends the identical chamfering of angle is arranged, or be angle of lock.The inclined hole that is drilled with fixing spring at the positioning pin hole middle part that tooth puts is in correct neutral position in the V-ring groove of steel ball top in the middle part of the V-shaped groove locating stud to guarantee synchronizer, and the V-shaped groove locating stud can axially move with the tooth cover.
When speed changer changes to third gear by second gear, the tooth cover be subjected to declutch shift shaft to thrust be moved to the left, the tooth cover is moved to the left by steel ball and V-shaped groove locating stud drive awl dish it is contacted with corresponding conical ring, conical ring with speed discrepancy coils once contact with awl and leans on the friction of surface of contact to make the awl dish turn over an angle together with the relative tooth cover of lock pin, thereby the journal offset of the pin-and-hole that puts of the relative tooth of the axis of dovetail groove lock pin, so the chamfering at trapezoidal lock pin middle part and the chamfering of pin-and-hole end are conflicted mutually, to stop the tooth cover to continue reach, as shown in Figure 4, the axial thrust load F of the normal direction impacting force N on locking face this moment
2Act on the awl dish and make it and compress, thereby the tooth cover reaches rapidly synchronously with spline gear to be joined, play the moment of inertia disappearance of the gear of locking effect when only reaching synchronous, act on the tangential component F on the lock pin with conical ring
1Could be by lock pin awl dish, conical ring and gear together turn over an angle with respect to the tooth cover, make again and pin-and-hole centering, so the tooth cover just can overcome the resistance of steel ball easily and move axially along lock pin, finish engage a gear until engaging with the external splines gear ring of gear.
When speed changer changes to second gear by third gear, the tooth cover be subjected to declutch shift shaft to thrust move right, the tooth cover drives the awl dish by steel ball and V-shaped groove locating stud and moves right it is contacted with corresponding conical ring, finishes changing to of second gear.
The working procedure of four Five-gear synchronizers:
Shown in figure five, four Five-gear synchronizers are fixed on second, between toothholder two ends and four or five grades of gears, respectively establish a synchronizing ring, the end spline gear is arranged on the synchronizing ring, the section of spline tooth and profile with and the conical ring cylindrical that fixes of four or five grades of gears on spline tooth identical, an end of the spline tooth in an end of the spline tooth on two synchronizing ring and four or the five grades of teeth covers that join with it on round all is processed with chamfering (also being angle of lock); Synchronizing ring has the identical inner conical surface of conical friction face cone degree with conical ring, three synchronizer chocks are separately positioned in three axial grooves of fixing toothholder, and can move vertically, spring and the synchronizer lock pin that will be fixed in the chock are pressed to the tooth cover, make lock pin be embedded in synchronizing ring in the inner groove at tooth cover middle part together with chock and respectively be provided with three boss facing to an end of toothholder, stretch into respectively in three axial grooves, have only that the tooth cover can engage with the tooth of synchronizing ring when three boss are positioned at toothholder axial groove middle.
When speed changer hung five grades by four retainings, available shift fork was stirred the tooth cover, and was moved to the left together by lock pin drive chock, and its working principle and two third gear synchronizers are roughly the same.When the chock left end contacts with the raised head face of synchronizing ring, just promoting synchronizing ring shifts to the conical ring that fixes with a shaft transmission gear and contacts, make two conical surfaces just produce rubbing action once contact with speed discrepancy, conical ring promptly drives synchronizing ring with respect to the leading angle of tooth cover by rubbing action, to the synchronizing ring boss near a side of toothholder axial groove, about half transverse tooth thickness staggers when being positioned at groove central, the end relief that makes tooth cover just in time contradicts each other with the corresponding end relief of synchronizing ring and can not enter and engage, because shift fork applies an axial force to the tooth cover all the time, make tooth cover end relief compress the synchronizing ring end relief, so effect has normal pressure on the angle of lock inclined-plane of synchronizing ring, this power can be decomposed into axial force and tangential force, responsive to axial force is on synchronizing ring, and make it to compress with conical ring, thereby the spline gear of tooth cover and conical ring to be joined reaches synchronous rapidly, the moment of inertia that plays the gear of locking effect when only reaching synchronous disappears, tangential force just makes synchronizing ring draw back with respect to the tooth cover together with conical ring and gear and all parts of being attached thereto changes an angle, make the synchronizing ring boss move on to the centre of toothholder axial groove again, two spline tooths are no longer conflicted, the tooth cover was depressed lock pin and was continued to move to left to enter with the spline gear of synchronizing ring and engage this moment, the effect of synchronizing ring is finished, the tooth cover engages the back axial force and no longer exists with synchronizing ring, friction torque between the conical surface also disappears simultaneously, if this moment, the spline tooth of tooth cover spline tooth and conical ring was conflicted, then to above-mentioned similar, act on tangential component on the conical ring spline increment inclined-plane and make conical ring turn over an angle with respect to synchronizing ring and tooth cover, the tooth cover and the spline gear of conical ring are entered engage and finish five grades change to together with the part that links to each other on the gear.
When speed changer hangs fourth gear by five retainings, available shift fork is stirred the tooth cover and is moved right, and drive chock by lock pin and move right together, the chock right-hand member contacts with the raised head face of synchronizing ring, promoting synchronizing ring shifts to and fixes conical ring with two fourth gears and contact, make two conical surfaces with speed discrepancy just produce rubbing action once contact, its whole process is identical with the process of being changed five grades by fourth gear
Exchange between one grade, reverse gear is to finish by gearing device, engagement seats and second fix by bearing fixing fixing by gear ring at the one grade of gear and the reverse gear driving gear of engagement seats both sides, reverse shift fork is stuck in and stirs engagement cover move left and right in the circular groove that meshes on the cover cylindrical, with gear ring on one grade of gear and reverse gear driving gear engagement gear shift, realizes one grade of mutual switching with reverse gear.
The heavy duty automobile gear box of tape synchronizer of the present utility model is compared with prior art, and have reasonable in design, simple in structure, easy to operate, gear shift noise free, can improve the characteristics such as working life of gearbox, thereby, have good value for applications.
