Problems solved by technology

The operating conditions of agricultural machinery are worse than those of road vehicles, and they often encounter the situation of sharp increase in resistance. Small-power agricultural machinery often has to sacrifice a certain operating efficiency to overcome these extreme conditions, and there is also an increase in fuel consumption; However, agricultural machinery has problems such as high cost and large volume, and there is a problem of excess power under relatively good operating conditions.

Abstract

The invention provides a multi-mode continuously variable transmission with a rotating speed and torque coupling function. The multi-mode continuously variable transmission comprises an engine power input assembly, a hydraulic transmission assembly, a motor transmission assembly, a planetary gear assembly, an output component, a clutch component and a brake component, wherein the output end of theplanetary gear assembly is connected to the output component; the engine power input assembly, the hydraulic transmission assembly and the motor transmission assembly are connected to the input end of the planetary gear assembly through the clutch component; the engine power input assembly is connected to the hydraulic transmission assembly through the clutch component; and the clutch component and the brake component are used for providing a continuously changing transmission ratio of the engine power input assembly or / and the motor transmission assembly to the output component. Optimal power matching of a power source and optimal combination of power output modes can be achieved by switching the clutch component and the brake component and adjusting the displacement ratio of the hydraulic transmission assembly and the rotating speed / torque of a motor.

Description

technical field [0001] The invention relates to the field of variable speed transmission of vehicles, in particular to a multi-mode continuously variable transmission with speed and torque coupling. Background technique [0002] China is a big energy-consuming country with a shortage of oil resources, and most of the oil resources are consumed by vehicles. As countries around the world pay more and more attention to energy conservation and emission reduction, the fuel-saving solutions for agricultural machinery are also attracting attention. The operating conditions of agricultural machinery are worse than those of road vehicles, and they often encounter the situation of sharp increase in resistance. Small-power agricultural machinery often has to sacrifice a certain operating efficiency to overcome these extreme conditions, and there is also an increase in fuel consumption; The existing agricultural machinery has problems such as high cost and large volume, and there is a p...
