So, by each synchronous sleeve 21～24 and each clutch 2,3 are carried out to action control, thereby utilize selectively the 1st main shaft the 4, the 2nd main shaft 5 and the 1st countershaft 6, reverse shaft 7 and can finally set multiple paths via output shaft 8, utilize the combination of each gear, and can guarantee the velocity ratio of each speed change level.
In addition, as mentioned above, because the speed change level adjacent is switched two clutches 2,3, therefore, in the time that speed change (gear up, gear down) arrives adjacent speed change level, before the clutch 2,3 connecting in the speed change level of cutting off before speed change, can, in advance with the grading action edge transmission of speed change of speed change target, can shift gears in advance.In detail, in the time carrying out gear up, gear down, the clutch connecting in the speed change level of cutting off before speed change 2,3 o'clock, by making each synchronous sleeve 21～24 actions guarantee the bang path of the speed change level of speed change target, thereby needs only switch clutch 2,3 with regard to variable speed.Thus, can promptly carry out gear up and gear down.
In the variable-speed motor portion 1 of the present embodiment, in the time of reversing, by being located at the 7th fixed gear 10c and the 6th fixed gear 15c transmission of drive force on reverse shaft 7.The 7th fixed gear 10c is configured to the 1st fixed gear 10a being fixed on the 1st main shaft 4 and engages, and the 6th fixed gear 15c engages with the 3rd unloaded gear 15b being located on the 1st countershaft 6.In addition the 4th fixed gear 12b being fixed on the 1st countershaft 6, engages with the 1st unloaded gear 12a being located on the 2nd main shaft 5.Therefore, can make the 2nd main shaft 5 with respect to the sense of rotation of the 1st main shaft 4 and to opposite spin.Thus, in when reversing, can make output shaft 8 when advancing (when 1～6 speed) sense of rotation and to opposite spin.
And, in this example, during by reversing, driven the 6th fixed gear 15c is configured to, overlapping with the 3rd fixed gear 14a in the axial direction, in the 2nd gear train (12a, 13a, 14a) of described the 3rd fixed gear 14a on the 2nd main shaft 5 with motor 100 nearest (nearest with the 1st fixed gear 10a).
Be located at i.e. the 7th fixed gear 10c of gear of the opposing party outside the 6th fixed gear 15c in two reverse-gears (10c, 15c) on reverse shaft 7, owing to being more configured in motor 100 sides than the 6th fixed gear 15c, therefore, will not extend to than the opposition side of the more close motor 100 of the 6th fixed gear 15c by reverse shaft 7.Therefore, the end of the 6th fixed gear 15c side of reverse shaft 7 can be enclosed in to motor 100 sides, thereby can suppress the axial length of reverse shaft 7.
In addition, because the 7th fixed gear 10c being located on reverse shaft 7 is configured to engage with the 1st fixed gear 10a (being configured to overlapping with the 1st fixed gear 10a in the axial direction), described the 1st fixed gear 10a in the 1st gear train (10a, 11a) being located on the 1st main shaft 4 from motor 100 (near the 3rd fixed gear 14a) farthest, therefore, the 7th fixed gear 10c and the 6th fixed gear 15c can be approached to configuration in the axial direction, can further shorten the axial length of reverse shaft 7.
So, by shortening the axial length of reverse shaft 7, thereby can alleviate the weight of reverse shaft 7 self, and can be by the part of the reverse shaft of storage case 32 7 (reverse shaft container 32a) in the axial direction than the part (main shaft container 32b) of storage the 2nd main shaft 5 thus little miniaturization.Thus, weight and the cost of variable-speed motor portion 1 can be reduced, and the vehicle boarded property of variable-speed motor portion 1 can be improved.
In addition, by shortening the axial length of reverse shaft 7, can suppress the torsion of reverse shaft 7, thus the transmission efficiency of the power in variable-speed motor portion 1 can improve reversing time.
In addition, because reverse shaft 7 leaves the foreign side that is configured in the 1st countershaft 6, and, the reverse-gear being located on reverse shaft 7 is made up of multiple gears of the 6th fixed gear 15c and the 7th fixed gear 10c, therefore, the 6th fixed gear 15c and the 7th fixed gear 10c can select larger diameter, and the setting degrees of freedom of the velocity ratio of reverse-gear improves, and can make the design transfiguration of variable-speed motor portion 1 easy.
In addition, in the present embodiment, in the axial direction of reverse shaft 7, between the 6th fixed gear 15c and the 7th fixed gear 10c, dispose the 2nd synchronous sleeve 22 and the 4th synchronous sleeve 24.So, by configuring the 2nd synchronous sleeve 22,24, although it is large that the distance of the reverse shaft 7 between the 6th fixed gear 15c and the 7th fixed gear 10c likely becomes slightly, but between the 6th fixed gear 15c and the 7th fixed gear 10c, by utilizing the space on the axle of the 7th countershaft 6 and output shaft 8 to configure two synchronous sleeves 22,24, thereby can suppress the axial size of variable-speed motor portion 1 entirety.
