Electric drive gearbox of construction machine

The present invention relates to an electric drive gearbox of a construction machine. The electric drive gearbox is an electric drive fixed-spindle structure capable of realizing two gears or three gears, can meet gear requirements of construction machines such as road graders and rough terrain cranes, and has a gear velocity ratio adjustable within a range of 0.8-6.5. At low gear, the transmission route is longest, and the sizes of gears are uniform, so as to achieve a large velocity ratio and bear a large torque. High gear corresponds to the shortest transmission route, and can achieve rapid switching to a small velocity ratio for torque transmission and minimum power loss. Conversion between a multi-gear structure and a less-gear structure can be realized simply and economically by adding or removing an intermediate shaft as well as a clutch and a gear on the intermediate shaft, and the application and maintenance costs of using the multi-gear structure as a less-gear structure is reduced. The gearbox provided by the present invention uses a single-clutch structure, has a simple structure, is easy to machine and manufacture, and can avoid system deformation caused by a long spindle length in a case of a twin-clutch structure, thereby improving the gear transmission precision, reducing noise of a transmission, and improving stability.
