Abstract

The invention provides a multi-mode hybrid power-composite transmission power transmission device. The transmission device comprises an internal combustion engine power system, a planetary gear assembly, an output member, a motor power system, a hydraulic transmission system, a clutch assembly and a brake assembly, wherein the planetary gear assembly comprises at least three planetary gear trains;the internal combustion engine power system is connected with the hydraulic transmission system; the output member is connected with the planetary gear assembly; the clutch assembly connects the internal combustion engine power system, the motor power system and the hydraulic transmission system to the planetary gear assembly; and the clutch assembly and brake assembly provide continuous transmission ratio between the internal combustion engine power system or / and the motor power system and the output member. By combining the structural design of the transmission device and a braking energy management system, the recovery and release of braking energy are realized and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the field of variable speed transmission boxes, in particular to a multi-mode hybrid power-compound transmission power transmission device. Background technique [0002] A relatively complete power transmission device is mainly composed of power source, transmission device, traveling device and control system. In terms of power sources, in addition to mature single-source drive technologies such as internal combustion engines and chemical power sources, hybrid vehicles that combine internal combustion engines and electric motors have attracted more and more attention; In addition to single-flow transmissions such as hydraulic transmissions, compound transmissions can often abandon the shortcomings of single-flow transmissions and give full play to their advantages; as far as the running gear is concerned, the running gear and steering gear can be separated or combined to meet different design requirements; in terms of control ...
