Detailed Description
The invention is further described below with reference to the accompanying drawings:
example one
As shown in fig. 1, a novel six-gear transmission includes an input shaft 11, an output shaft 12, an intermediate shaft 13, a reverse gear reversing shaft 14, a forward gear moving gear and a reverse gear moving gear 7 which are arranged on the input shaft 11, a forward gear driven gear and a gear shifting output gear 808 which are arranged on the intermediate shaft 13, a gear shifting access gear 8 which is arranged on the output shaft 12, a reversing gear 9 which is arranged on the reverse gear reversing shaft 14, a reverse gear driven gear 707, a forward gear synchronizer and a reverse gear synchronizer 10; the input shaft 11 and the output shaft 12 are arranged coaxially in the front and back direction, the intermediate shaft 13 is arranged in parallel with the input shaft 11 and the output shaft 12, and the reverse reversing shaft 14 is arranged in parallel with the intermediate shaft 13 and the input shaft 11 respectively; each forward gear moving gear can be respectively combined with each forward gear driven gear through a corresponding synchronizer; the reverse driven gear 707 is arranged on an intermediate shaft 13 corresponding to the reverse driven gear 7, the reverse driven gear 7 is constantly meshed with the reversing gear 9, and the reversing gear 9 can be combined with the reverse driven gear 707 through a reverse synchronizer 10; the reverse gear synchronizer 10 is arranged on an intermediate shaft 13; a shift output gear 808 is provided on countershaft 13 and is in constant mesh with shift access gear 8.
The forward gear moving gear includes: the gear comprises a forward first-gear moving gear 1, a forward second-gear moving gear 2, a forward third-gear moving gear 3, a forward fourth-gear moving gear 4, a forward fifth-gear moving gear 5 and a forward sixth-gear moving gear 6.
The forward range slave gear includes: a first forward gear driven gear 101, a second forward gear driven gear 202, a third forward gear driven gear 303, a fourth forward gear driven gear 404, a fifth forward gear driven gear 505, and a sixth forward gear driven gear 606.
The forward gear synchronizer corresponding to each gear comprises:
a second-gear synchronizer 102 is used between the forward first-gear moving gear 1 and the forward first-gear driven gear 101 and between the forward second-gear moving gear 2 and the forward second-gear driven gear 202.
The third-fourth synchronizer 304 is used between the third forward gear 3 and the third forward gear 303 and between the fourth forward gear 4 and the fourth forward gear 404.
A fifth-sixth synchronizer 506 is used between the forward fifth-speed moving gear 5 and the forward fifth-speed driven gear 505, and between the forward sixth-speed moving gear 6 and the forward sixth-speed driven gear 606, respectively.
The forward and reverse synchronizers 7 may be provided on the input shaft 11 or on the intermediate shaft 13.
The forward gear moving gear of each gear can be combined with the forward gear driven gear of the gear through the corresponding forward gear synchronizer to establish a transmission relation.
After the arrangement, the reverse synchronizer 7 is combined rightwards, the power of the output shaft 12 is transmitted to the reversing gear 9 through the reverse moving gear 7, transmitted to the reverse driven gear 707 through the reversing gear 9, transmitted to the intermediate shaft 13 through the reverse driven gear 707, and transmitted to the output shaft 12 through the intermediate shaft 13, the gear shifting output gear 808 and the gear shifting access gear 8.
According to the above arrangement, when any one of the forward gears is engaged, the intermediate shaft 13 rotates in one direction. When the reverse gear is engaged, the intermediate shaft 13 rotates in the opposite direction. Thus, in contrast to the prior art (see fig. 2), there is no need to provide a separate reverse shaft 15 for reverse gear, nor to provide an axial bore in the intermediate shaft 13 for mounting the reverse shaft 15. On the premise of obtaining the same gear selecting and shifting effect, the gearbox is simpler in structure, and the manufacturing cost is obviously reduced. Meanwhile, the arrangement is that the intermediate shaft 13 can rotate reversely only when the reverse gear is engaged, and the reverse gear is used less frequently compared with the forward gear, so that the energy is saved compared with the prior art that a special reverse gear shaft 15 needs to rotate normally.
Further, a reverse driven gear 707 and a reverse driven gear 7 are provided at the front end of the intermediate shaft 13 and the front end of the input shaft 11, respectively, and the shift output gear 808 is provided at the rear end of the intermediate shaft 13. Therefore, the forward gears are conveniently arranged from the gear in a concentrated mode, and the arrangement of the gear selecting and shifting mechanism can be facilitated.
Example two
As shown in fig. 2, it is different from the first embodiment in that: the reversing gear 9 is constantly meshed with a reverse driven gear 707, the reversing gear 9 can be combined with the reverse moving gear 7 through a reverse synchronizer 10, and the reverse synchronizer 10 is arranged on an input shaft 11. The difference from the first embodiment is that the reverse reversing shaft 14 only rotates along with the input shaft 11 when the vehicle needs to be reversed, which is relatively more energy-saving when in use.
The above embodiments are only for the purpose of more clearly describing the invention and should not be considered as limiting the scope of protection covered by the invention, any modification of the equivalent should be considered as falling within the scope of protection covered by the invention.
