Problems solved by technology

However, in the above-mentioned shifting methods, a gear needs to be provided with a corresponding set of gear pairs. When the speed ratio is relatively large, according to the characteristics of the gear meshing transmission, the center distance between the input shaft and the output shaft is too large, which in turn causes the transmission to move radially. When the volume increases, or the required gears increase, the number of gear pairs increases, which increases the overall weight of the transmission, which is not conducive to its placement in the vehicle

Abstract

The invention relates to the technical field of vehicle engineering, in particular to a transmission, a power assembly and power equipment. The transmission comprises: a shell, an input shaft system, intermediate shaft systems and a planetary gear system, wherein the planetary gear system comprises an output shaft, a sun gear and a third synchronizer, a second driven part is arranged on the output shaft and cooperates with a second driven part, and a second synchronizer is combined with or separated from the second driven part, and the third synchronizer is arranged on a gear ring, and can be combined with or separated from the shell and a planet carrier. Compared with the prior art, the use of transmission pairs is at least reduced, so that the weight of the whole transmission can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a transmission, a power assembly, and power equipment. Background technique [0002] Under the strategic needs of reducing carbon emissions, promoting the development and utilization of renewable energy, and realizing energy diversification, electric vehicles have gradually become a green choice for travel and transportation. [0003] Electric vehicles are mainly powered by on-board power supplies, and use motors to drive vehicles to run. Electric vehicles are similar to fuel vehicles with transmissions. In different driving scenarios, the speed requirements of the vehicle are very different. Therefore, it is necessary to configure a transmission between the motor and the drive shaft of the vehicle to realize the adjustment of the vehicle speed. Make sure to match the appropriate driving speed in different scenarios, so that the motor can be in the high-efficiency zo...
