It can be considered that the first output gear 3011 and the first input gear 2021 are meshed to form a first gear group; the second output gear 3012 is meshed with the second input gear 2022 to form a five-gear set; the third output gear 3013 and the third input gear 2023 are engaged to form a four-gear set; the fourth output gear 3014 and the fourth input gear 2024 are meshed to form a three-gear set; the fifth output gear 3015 and the fifth input gear 2025 are engaged to form a two-gear set.

The second input gear 2022 and the fourth input gear 2024 are connected to the intermediate shaft 20 through bushings, respectively; that is, the relative positions of the second input gear 2022 and the fourth input gear 2024 and the intermediate shaft 20 are fixed, and when the intermediate shaft 20 rotates, the second input gear 2022 and the fourth input gear 2024 do not rotate, which means that the second input gear 2022 and the fourth input gear 2024 are empty on the intermediate shaft 20.

The second output gear 3012 and the fourth output gear 3014 are connected to the output shaft 30 through splines respectively; that is, the second output gear 3012 and the fourth output gear 3014 are movable in the axial direction of the output shaft 30, and when the output shaft 30 rotates, the second output gear 3012 and the fourth output gear 3014 rotate.
In this embodiment, different gears are connected to the corresponding shafts in different manners, and one gear of the set of gears engaged with each other is fixedly connected to the shaft or connected to the shaft through a spline, and the other gear of the set of gears is connected to the shaft through a bushing. Through the arrangement, the rotation condition of the gear can be conveniently adjusted, so that the gear shaft mechanism of the gearbox with the same-side transmission can operate in different gears.
Optionally, a first groove is formed on the third input gear 2023 on the side close to the fourth input gear 2024, and the first groove is used for accommodating a first fork which is used for controlling the third input gear 2023 to move along the axial direction of the intermediate shaft 20;
a second groove is formed in one side, close to the third output gear 3013, of the second output gear 3012, and is used for accommodating a second shifting fork, and the second shifting fork is used for controlling the second output gear 3012 to move along the axial direction of the power output shaft 30;
and a third groove is formed in one side, close to the third output gear 301, of the fourth output gear 3014, and is used for accommodating a third shifting fork which is used for controlling the fourth output gear 3014 to move along the axial direction of power output.
In the first case, since the first input gear 2021 is fixedly connected to the intermediate shaft 20, the first input gear 2021 rotates when the intermediate shaft 20 rotates. At this time, the second output gear 3012 is shifted to the first output gear 3011 by the third shift fork, and is connected to the first output gear 3011. The first output gear 3011 rotates by being engaged with the first input gear 2021, and since the second output gear 3012 is connected to the first output gear 3011, the power of the first output gear 3011 can be output to the output shaft 30 through the spline of the second output gear 3012. Therefore, at this time, power is output from the first output gear 3011, and the gearbox gear shaft mechanism transmitting on the same side at this time can be considered to be in the first gear operation state.
In the second case, since the fifth input gear 2025 is spline-connected to the counter shaft 20, the fifth input gear 2025 rotates when the counter shaft 20 rotates. At this time, the fourth output gear 3014 is shifted toward the fifth output gear 3015 by the fourth shift fork, and is connected to the fifth output gear 3015. The fifth output gear 3015 rotates by being engaged with the fifth input gear 2025, and since the fifth output gear 3015 is connected to the fourth output gear 3014, the power of the fifth output gear 3015 can be output to the output shaft 30 through the spline of the fourth output gear 3014. Therefore, at this time, power is output from the fifth output gear 3015, and it can be considered that the gear shaft mechanism of the transmission that transmits on the same side is in the second-gear operation state at this time.
In the third case, since the fourth input gear 2024 is connected to the intermediate shaft 20 via a bushing, the fourth input gear 2024 does not rotate when the intermediate shaft 20 rotates. At this time, the third input gear 2023 is shifted toward the fourth input gear 2024 by the first shifter, and is connected to the fourth input gear 2024, and at this time, the fourth input gear 2024 rotates. At this time, the fourth output gear 3014 rotates by meshing with the fourth input gear 2024, and the fourth output gear 3014 outputs power to the output shaft 30 through splines. Therefore, at this time, power is output from the fourth output gear 3014, and the transmission gear shaft mechanism transmitting power on the same side at this time can be considered to be in the third-gear operation state.
In the fourth case, since the third input gear 2023 is spline-connected to the intermediate shaft 20, when the intermediate shaft 20 rotates, the third input gear 2023 rotates. At this time, the fourth output gear 3014 is shifted toward the third output gear 3013 by the fourth shift fork, and is connected to the third output gear 3013. The third output gear 3013 rotates due to being meshed with the third input gear 2023, and the fourth output gear 3014 is connected to the third output gear 3013, so that the power of the third output gear 3013 can be output to the output shaft 30 through the spline of the fourth output gear 3014, and therefore the power is output by the third output gear 3013 at this time, and it can be considered that the transmission gear shaft mechanism transmitting on the same side is in the fourth-gear operation state at this time.
In the fifth case, since the second input gear 2022 is connected to the intermediate shaft 20 via a bushing, the second input gear 2022 does not rotate when the intermediate shaft 20 rotates. At this time, the third input gear 2023 is shifted toward the second input gear 2022 by the first shifter, and is connected to the second input gear 2022, and at this time, the second input gear 2022 rotates. At this time, the second output gear 3012 rotates by meshing with the second input gear 2022, and the second output gear 3012 outputs power to the output shaft 30 through splines. Therefore, at this time, power is output from the second output gear 3012, and the transmission gear shaft mechanism transmitting power on the same side at this time can be considered to be in a fifth-gear operation state.
It should be understood that the first, second and third forks are respectively connected to a shift drum, by which the movement of the first, second and third forks can be controlled, so that the gear shaft mechanism of the transmission case with the same side does not output power through two gears at the same time.
In this embodiment, through the arrangement of the first, second and third forks, it is possible to move the position of the gear connected with the shaft through the spline by the fork, thereby outputting power through different gears. Through the setting of first shift fork, second shift fork and third shift fork, improved the control the operating convenience of the driven gearbox pinion mechanism running state of homonymy.
