the steering shaft 40 is sleeved with a reverse intermediate gear 401, and the reverse intermediate gear 401 is respectively meshed with the reverse input gear 2021 and the reverse output gear 3011, so that the rotation direction of the reverse output gear 3011 is opposite to that of the power input gear 101.
It should be understood that a starting mechanism, which in one embodiment is an engine, is connected to one end of the input shaft 10. The power input gear 101 is powered by the activation mechanism such that the power input gear 101 rotates.
It should be understood that the position of the reverse input gear 2021 is not limited thereto. For example, in one embodiment, the reverse input gear 2021 is located on a side of the first forward input gear 2022 that is distal from the second forward input gear 2023. In another embodiment, the reverse input gear 2021 is located between the third forward input gear 2024 and the fourth forward input gear 2025. Further, since the reverse intermediate gear 401 is engaged with the reverse input gear 2021 and the reverse output gear 3011, respectively, the positions of the reverse intermediate gear 401 and the reverse output gear 3011 are also adjusted according to the position of the reverse input gear 2021.
It should be understood that the first, fifth, fourth, third and second forward output gears 3012, 3016, 3015, 3014 and 3013 are sequentially reduced in diameter size. Since the diameters of the gears are inversely proportional to the rotation speed, the rotation speeds of the first forward output gear 3012, the fifth forward output gear 3016, the fourth forward output gear 3015, the third forward output gear 3014 and the second forward output gear 3013 are sequentially increased. It can be considered that the first forward output gear 3012 and the first forward input gear 2022 are meshed to form a first gear group; the second forward output gear 3013 and the second forward input gear 2023 are engaged to form a five-gear set; the third forward output gear 3014 and the third forward input gear 2024 are engaged to form a four-gear set; the fourth forward output gear 3015 and the fourth forward input gear 2025 are engaged to form a three-gear set; the fifth forward output gear 3016 and the fifth forward input gear 2026 are engaged to form a two-gear set.
In practical use, the transmission gear shaft mechanism with reverse gear provided by the embodiment first drives the power input gear 101 to rotate through the starting mechanism. Since the power input gear 101 is engaged with the power output gear 201, the power input gear 101 rotates the power output gear 201, and simultaneously the power output gear 201 rotates the intermediate shaft 20. Because the power output gear 201 and the driving gear set are sleeved on the intermediate shaft 20, the rotation directions of the power output gear 201 and the driving gear set are the same. Furthermore, since the two gears of the engaged gear set rotate in opposite directions, the first forward output gear 3012, the second forward output gear 3013, the third forward output gear 3014, the fourth forward output gear 3015 and the fifth forward output gear 3016 rotate in the same direction as the power input gear 101, and at this time, the wheel rotates clockwise, so as to advance the wheel.

Since the reverse counter gear 401 is engaged with the reverse input gear 2021, the reverse counter gear 401 rotates in the opposite direction to the reverse input gear 2021. Since the reverse intermediate gear 401 is also meshed with the reverse output gear 3011, the reverse output gear 3011 rotates in the same direction as the reverse input gear 2021, that is, the reverse output gear 3011 rotates in the opposite direction to the power input gear 101, and at this time, the wheels rotate counterclockwise, so as to reverse the vehicle.

It should be understood that in practical use, the transmission gear shaft mechanism with reverse gear provided in the present embodiment first drives the power input gear 101 to rotate through the starting mechanism, and transmits power to the power output gear 201, and drives the intermediate shaft 20 to rotate.
In the first case, since the first forward input gear 2022 is fixedly connected to the intermediate shaft 20, the first forward input gear 2022 rotates when the intermediate shaft 20 rotates. At this time, the second forward output gear 3013 is shifted to the first forward output gear 3012 by the third shift fork, and is connected to the first forward output gear 3012. The first forward output gear 3012 rotates by being engaged with the first forward input gear 2022, and since the second forward output gear 3013 is connected to the first forward output gear 3012, the power of the first forward output gear 3012 can be output to the output shaft 30 through the spline of the second forward output gear 3013. Therefore, power is output from the first forward output gear 3012, and the transmission gear shaft mechanism with the reverse gear is considered to be in the first gear operation state.
In the second case, since the fifth forward input gear 2026 is splined to the intermediate shaft 20, the fifth forward input gear 2026 rotates when the intermediate shaft 20 rotates. At this time, the fourth forward output gear 3015 is shifted to the fifth forward output gear 3016 by the fourth shift fork, and is connected to the fifth forward output gear 3016. The fifth forward output gear 3016 rotates by being engaged with the fifth forward input gear 2026, and since the fifth forward output gear 3016 is connected to the fourth forward output gear 3015, the power of the fifth forward output gear 3016 can be output to the output shaft 30 through the spline of the fourth forward output gear 3015. Therefore, power is output from the fifth forward output gear 3016, and the transmission gear mechanism with the reverse gear is considered to be in the second gear operation state.
In the third case, since the fourth forward input gear 2025 is connected to the intermediate shaft 20 via a bushing, the fourth forward input gear 2025 does not rotate when the intermediate shaft 20 rotates. At this time, the third forward input gear 2024 is shifted toward the fourth forward input gear 2025 by the first shift fork, and is connected to the fourth forward input gear 2025, and at this time, the fourth forward input gear 2025 rotates. At this time, the fourth forward output gear 3015 rotates by meshing with the fourth forward input gear 2025, and the fourth forward output gear 3015 outputs power to the output shaft 30 through splines. Therefore, at this time, power is output from the fourth forward output gear 3015, and the transmission gear shaft mechanism having the reverse gear can be considered to be in the third gear operation state.
In the fourth case, since the third forward input gear 2024 is spline-connected to the intermediate shaft 20, the third forward input gear 2024 rotates when the intermediate shaft 20 rotates. At this time, the fourth forward output gear 3015 is shifted to the third forward output gear 3014 by the fourth shift fork, and is connected to the third forward output gear 3014. The third forward output gear 3014 is rotated by meshing with the third forward input gear 2024, and the fourth forward output gear 3015 is connected to the third forward output gear 3014, so that the power of the third forward output gear 3014 can be output to the output shaft 30 through the spline of the fourth forward output gear 3015, and therefore the power is output from the third forward output gear 3014 at this time, and it can be considered that the transmission gear shaft mechanism having the reverse gear is in the fourth gear operation state at this time.
In the fifth case, since the second forward input gear 2023 is connected to the intermediate shaft 20 via a bushing, the second forward input gear 2023 does not rotate when the intermediate shaft 20 rotates. At this time, the third forward input gear 2024 is shifted toward the second forward input gear 2023 by the first shift fork, and is connected to the second forward input gear 2023, and at this time, the second forward input gear 2023 rotates. At this time, the second forward output gear 3013 rotates by meshing with the second forward input gear 2023, and the second forward output gear 3013 outputs power to the output shaft 30 through splines. Therefore, at this time, power is output from the second forward output gear 3013, and the transmission gear shaft mechanism having the reverse gear can be considered to be in the fifth-gear operation state.
In the sixth case, since the reverse input gear 2021 is connected to the counter shaft 20 via a bushing, the reverse input gear 2021 does not rotate when the counter shaft 20 rotates. At this time, the fifth forward input gear 2026 is shifted to the reverse input gear 2021 by the second shift fork, and is connected to the reverse input gear 2021, and at this time, the reverse input gear 2021 rotates. At this time, the reverse intermediate gear 401 rotates by being engaged with the reverse input gear 2021, and at the same time, rotates the reverse output gear 3011. The reverse output gear 3011 is fixedly connected to the output shaft 30, and outputs power to the output shaft 30. Therefore, at this time, power is output from the reverse output gear 3011, and the transmission gear mechanism having the reverse gear is considered to be in the reverse gear operation state.
It should be understood that the first, second, third and fourth forks are respectively connected with a shift drum through which the movement of the first, second, third and fourth forks is controlled so that the gear shaft mechanism of the transmission having a reverse gear does not output power through two gears at the same time.
In this embodiment, through the arrangement of the first, second, third and fourth forks, it is possible to move the position of the gear connected with the shaft through the spline by the forks, thereby outputting power through different gears. Through the setting of first shift fork, second shift fork, third shift fork and fourth shift fork, improved the control the gearbox pinion mechanism running state's that has the reverse gear simple operation nature.
