The present utility model will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the substances, and not restrictive of the utility model. It should be further noted that, for convenience of description, only the portions related to the present utility model are shown in the drawings.
In addition, the embodiments of the present utility model and the features of the embodiments may be combined with each other without collision. The present utility model will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Due to the very wide weight range of commercial vehicles carrying cargo, cargo loading from empty to 50, 60 tons and heavier occurs; the transportation distance is various and is from tens of kilometers to thousands of kilometers, the transportation road condition is various, and the road has a flat road, a small ramp, a large ramp, a dry road, a soft road, a muddy road and the like. In order to ensure the vehicle operation capability and operation efficiency under various working conditions, the power output to the vehicle under different working conditions is also diversified, so that the vehicle obtains a certain speed, can provide enough traction force, and has higher efficiency.
The transmission of the electric commercial vehicle in the current market has lower head gear speed due to structural layout, or has no direct gear configuration, so that the vehicle configuration cannot simultaneously meet the maximum climbing traction requirement and the average maximum road speed requirement, or has no direct gear, and the maximum transmission efficiency is reduced.
Referring to fig. 1-2, an embodiment of the present utility model provides a transmission 100 including an input shaft 10, a planetary gear mechanism P1, a gear assembly, and an output shaft 11 coaxial with the input shaft 10, where the coaxial arrangement of the input shaft 10 and the output shaft 11 means that the input shaft and the output shaft are coaxial and are independent shafts. The planetary gear mechanism P1 is provided on the input shaft 10; when the transmission 100 is in the first transmission mode, the input shaft 10 is in transmission connection with a gear assembly through the planetary gear mechanism P1, the gear assembly being in transmission connection with the output shaft 11; when the transmission 100 is in the second drive mode, the input shaft 10 is in driving connection with the output shaft 11 through the gear assembly; when the transmission 100 is in the third drive mode, the input shaft 10 is in driving connection with the output shaft 11.
When the transmission 100 needs the first transmission mode, the power of the input shaft 10 is transmitted to the gear transmission assembly through the planetary gear mechanism P1, the gear transmission assembly is transmitted to the output shaft 11, and the output shaft 11 drives the wheels to move, and the planetary gear mechanism P1 has a speed reducing function, so that the first transmission mode is a low-speed gear; the gear transmission assembly can be designed to adjust the head gear to a larger speed ratio which is far greater than the head gear speed ratio 10 of the existing speed changer. When the transmission 100 is in the second transmission mode, the power of the input shaft 10 is transmitted directly to the gear assembly, not through the planetary gear mechanism P1, and is further transmitted to the output shaft for power output, and a high-speed gear is formed since the power is not reduced through the planetary gear mechanism P1. When the transmission 100 is in the third transmission mode, the input shaft 10 is directly connected with the output shaft 11 in a transmission mode, in other words, the power of the input shaft 10 does not pass through the planetary gear mechanism P1 and does not pass through the gear transmission assembly, so that direct gear power output is formed, no gear engagement transmission loss is caused, the highest transmission efficiency is realized, and the energy consumption is reduced. Therefore, the transmission 100 according to the embodiment of the present utility model can simultaneously satisfy the maximum creep traction requirement and the flat-road maximum vehicle speed requirement through the transition of the three modes, and can also obtain the highest transmission efficiency.
