Double-input gearbox assembly and operation method thereof

Abstract

The invention discloses a double-input gearbox assembly and an operation method thereof. The double-input gearbox assembly comprises a first input shaft, a second input shaft, a first intermediate shaft assembly, a second intermediate shaft assembly and an output shaft. The first input shaft is sleeved with a second input shaft, the first input shaft is connected with the output shaft, one side of the output shaft is provided with a first intermediate shaft assembly, the other side of the output shaft is provided with a second intermediate shaft assembly, the first input shaft and the second input shaft are connected with a power structure, and the power structure is connected with the gearbox. The gear force needing to be provided is selected firstly; the two independently-arranged input systems are used for carrying out gear shifting and speed regulation on the gearbox; a motor controller is used for reading the rotating speed in real time; the motor rotating speed device adjusts the rotating speeds of the two motors, gear coupling is achieved, it can be effectively guaranteed that the device adjusts the speed through the motors, simultaneous input of the two motors is achieved, it is guaranteed that the device can be engaged with the two gears, power coupling is achieved, and therefore the effects of saving energy, reducing consumption and saving cost are achieved.

Description

technical field [0001] The invention relates to the field of gearboxes, in particular to a dual-input gearbox assembly and an operation method thereof. Background technique [0002] At present, the general structure of domestic new energy and gearbox assemblies is that a motor and a gearbox assembly provide power input through the motor, and the gearbox assembly provides the function of changing the speed ratio and increasing the torque. [0003] However, under real conditions, when the input torque required by the whole vehicle increases, especially under heavy load uphill conditions, the motor needs to calculate the maximum output torque required by the motor according to the speed ratio of the gearbox. In the middle, the larger the output torque of the motor, the larger the inner coil of the motor is often required, the increase in the volume causes the increase in the production cost of the motor, and the difficulty in the layout of the whole vehicle. SUMMARY OF THE IN...

Problems solved by technology

[0003] However, under realistic conditions, when the input torque required by the vehicle increases, especially in the case of heavy load uphill, the motor needs to calculate the maximum output torque required by the motor according to the speed ratio of the gearbox. In the prior art Among them, increasing the output torque of the motor often requires an increase in the internal coil of the motor, which increases the production cost of the motor and increases the difficulty in the layout of the vehicle.
