Background technique
In manual transmission, AMT, double-clutch speed changer, gear change system is stirred corresponding shift fork by the shifting block of gearshift and is moved left and right along declutch shift shaft, the output shaft that the fork pin of the shift fork of movement drives corresponding tooth to be enclosed within speed changer again moves left and right, thus realizes corresponding gear shift work.The shifting system of dual-output shaft speed changer, each output shaft is typically provided with two tooth covers, each tooth cover is driven by the fork pin of a shift fork, therefore existing double output shaft shifting system is provided with four shift forks and two declutch shift shafts altogether, four shift forks one group between two, two shift forks with group are nested with on same declutch shift shaft.Wherein the shift fork of the second group stressed arm of force stirred when tooth overlaps will stir stressed arm of force when tooth overlaps much larger than the shift fork of first group, therefore the shift fork of the second group stressed moment of stirring when tooth overlaps will stir stressed moment when tooth overlaps much larger than the shift fork of first group, the amount of deformation of the shift fork of second group will much larger than the amount of deformation of the shift fork of first group, so just to efficiency and the smoothness generation adverse influence of gearshift, also adverse influence is had to the functional reliability of shifting system.
Model utility content
Main purpose of the present utility model is to provide a kind of shift fork group structure being applied to the shifting system of dual-output shaft speed changer.
The utility model technological scheme used is: a kind of shift fork group of shifting system of dual-output shaft speed changer, comprises the first declutch shift shaft, the second declutch shift shaft, the first shift fork, the second shift fork, the 3rd shift fork and the 4th shift fork; Wherein the first shift fork, the second shift fork are nested with on the first declutch shift shaft, and the 3rd shift fork, the 4th shift fork are nested with on the second declutch shift shaft; First shift fork, the second shift fork are respectively used to stir the first tooth cover be nested with on the first output shaft of dual-output shaft speed changer, the second tooth cover; 3rd shift fork, the 4th shift fork are respectively used to stir the 3rd tooth cover be nested with on the second output shaft of dual-output shaft speed changer, the 4th tooth cover; Distance between first declutch shift shaft and the first output shaft is less than the distance between the second declutch shift shaft and the second output shaft; In addition, the shift fork group of the shifting system of described dual-output shaft speed changer also includes the 3rd declutch shift shaft, and described 3rd declutch shift shaft is located between the second declutch shift shaft and the second output shaft, and the 3rd shift fork and the 4th shift fork are nested with on the 3rd declutch shift shaft simultaneously.
The utility model, by the 3rd set declutch shift shaft, reduce the 3rd shift fork, the 4th shift fork when stirring corresponding tooth cover tooth cover to the 3rd shift fork, the 4th shift fork apply make the 3rd shift fork, the arm of force that the 3rd shift fork occurs bending and deformation, thus reduce the 3rd shift fork, moment that the 4th shift fork is badly deformed, namely can reduce the amount of deformation of the 3rd shift fork, the 4th shift fork, and then be conducive to the efficiency and the smoothness that improve gearshift operation, be conducive to the functional reliability improving shifting system simultaneously.
As preferably, the second declutch shift shaft, the 3rd declutch shift shaft and the second output shaft are triangularly arranged.This preferred version, structure stability is high, arranges easily.
As preferably, the 3rd shift fork, the 4th shift fork are nested with on the 3rd declutch shift shaft by linear bearing or selflubricating cover.This preferred version, can reduce the resistance that the 3rd shift fork, the 4th shift fork are movable on the 3rd declutch shift shaft, thus is conducive to improving the reliability of the efficiency of gearshift operation, smoothness and shift fork group.
In sum, the beneficial effect that the utility model brings is: by the 3rd set declutch shift shaft, reduce the 3rd shift fork, the 4th shift fork when stirring corresponding tooth cover tooth cover to the 3rd shift fork, the 4th shift fork apply make the 3rd shift fork, the arm of force that the 3rd shift fork occurs bending and deformation, thus reduce the 3rd shift fork, moment that the 4th shift fork is badly deformed, namely can reduce the amount of deformation of the 3rd shift fork, the 4th shift fork, and then be conducive to the efficiency and the smoothness that improve gearshift operation, be conducive to the functional reliability improving shifting system simultaneously.
