Abstract

The invention belongs to the technical field of power transmission, in particular to a stepless transmission device. According to the technical scheme, a four-segment hydraulic mechanical composite transmission device comprises an input shaft, an output shaft, a planetary transmission component, a fixed shaft gear transmission component, a hydraulic speed regulating component, a segment-change operating component and an idler. One Lavina planetary mechanism is adopted as foundation, a multi-shaft fixed shaft gear and a synchronizer are utilized completely, three shunt modes of different-speed integrated torque, different-speed integrated speed and different-torque integrated speed are engaged reasonably, a four-segment continuous stepless speed change transmission structure, and the four-segment hydraulic mechanical composite transmission device has the advantages of simple structure, small size and the like; furthermore, by the aid of the four-segment hydraulic mechanical composite transmission device, purely mechanical transmission conditions of reverse gear and six fixed gears can be realized.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a stepless transmission device. Background technique [0002] The vehicle transmission system is an important part of the vehicle propulsion system, and its performance has a great impact on the power, fuel economy, emissions and reliability of the entire vehicle. The multi-stage hydraulic mechanical continuous stepless transmission system has the advantages of wide stepless speed regulation range, good starting characteristics and high transmission efficiency. It can optimize the working state of the engine according to the road surface conditions, so that the vehicle can obtain the best driving performance. It is an ideal transmission form that can meet the requirements of vehicle economy, power and comfort. This is of great significance in the 21st century where energy shortages and environmental pollution are increasing. [0003] At present, foreign r...
