Variable-speed transmission system special for hybrid power automobile

Abstract

The invention provides a variable-speed transmission system special for a hybrid power automobile. The system comprises an engine (1), a first motor (3), a second motor (4), a second motor transmission assembly (5), a first clutch (6), a double-clutch assembly (7), a first gear gear set (8), a second gear gear set (9), a third gear gear set (10), a synchronizer (11), a first input shaft (13) and asecond input shaft (14). The engine (1) is connected with the first clutch (6). The first clutch (6) is connected with the first motor (3) and the first input shaft (13). One end of the double-clutchassembly (7) is connected with the first input shaft (13), and the other end of the double-clutch assembly (7) is connected with the second input shaft (14). The second motor (4) is connected with the third gear gear set (10). The three clutches and three gears are configured, the requirement for a power source is lowered, meanwhile, multiple working manners can be achieved, and efficient workingis achieved.

Description

technical field [0001] The invention relates to the technical field of hybrid power, in particular to a variable speed transmission system specially used for hybrid power vehicles. Background technique [0002] With a series of social problems caused by the continuous increase of vehicle ownership, the depletion of fossil energy and the deterioration of the atmospheric environment, the state has issued policies to encourage and require the development of new energy vehicles. However, pure electric new energy vehicles are affected by subjective and objective factors such as inconvenient charging and short cruising range, and the actual experience brought to users is not good. Hybrid vehicles, also in the field of new energy vehicles, have gradually gained the favor of the market due to their superior energy saving and emission reduction and relatively excellent user experience. [0003] Most of the existing hybrid power systems are developed based on traditional automatic tr...

AI Technical Summary

Problems solved by technology

[0004] 1. Higher requirements for motors and engines lead to higher costs;

[0005] 2. The working mode is single and cannot be adjusted according to the user's actual working conditions, which affects the fuel saving rate;

[0006] 3. When the system has a high-voltage fault or the battery is insufficient, it cannot be driven or the power is poor
