Abstract

The invention provides a continuously variable transmission system achieving multi-mode switching of hybrid power. The continuously variable transmission system comprises an input component, an outputcomponent, a clutch assembly, a brake, a hydraulic transmission assembly and a planetary gear assembly. The input component is connected with the hydraulic transmission assembly. The output componentis connected with the planetary gear assembly. The clutch assembly connects the input component and the hydraulic transmission assembly to the planetary gear assembly. The brake and the clutch assembly provides the transmission ratio of continuous advancing or retreating between the input component and the output component. Through linear increase or non-linear increase of the displacement ratioof the hydraulic transmission assembly, hydraulic-mechanical transmission is converted into mechanical transmission. Integrated control can be carried out through a dual power source adopting an engine and an electromotor as power and the transmission and composite transmission adopting hydraulic transmission, mechanical transmission and hydraulic-mechanical transmission as the transmission manner, the statistical method based on test data is used, and matched energy management strategies are provided.

Description

technical field [0001] The invention relates to the field of continuously variable transmission devices, in particular to a hybrid multi-mode switching continuously variable transmission system. Background technique [0002] Hydraulic transmission realizes flexible operation through the conversion of energy forms, but the transmission efficiency is relatively low; the transmission ratio of mechanical transmission generally changes in steps, and the transmission efficiency is relatively high. Hydro-mechanical transmission combines the advantages of hydraulic transmission and mechanical transmission. It has the advantages of stepless speed change, high transmission efficiency and large transmission power. It is an ideal transmission form for heavy vehicles. Hydraulic-mechanical transmission is divided into two types: input shunt and output shunt, each has its own advantages and disadvantages; and the mechanical-hydraulic composite transmission system integrating hydraulic tran...
