Hybrid power coupled system and vehicle

Technical field

The utility model belongs to new-energy automobile field, more particularly to hybrid power coupled system and vehicle.

Background technique

Dynamical system includes engine (internal combustion engine) and a power train being made of speed changer, differential mechanism and transmission shaft System；Its effect is driving power needed for providing driving wheel to vehicle.Internal combustion engine has certain speed and torque range, and Wherein reach optimal working condition in the range of very little, at this moment or oil consumption is minimum or noxious emission is minimum or two All so.However, actual road conditions are ever-changing, in the speed for not only showing driving wheel, while being also manifested by required by driving wheel Torque.Therefore, realize that revolving speed and the torque of internal combustion engine are optimal, i.e. power optimum state, the matching with driving wheel dynamic regime It is good, it is the top priority of speed changer.

Speed changer currently on the market mainly has step change transmission and stepless transmission two major classes.Step change transmission segments again It is manually and automatically two kinds.They are arranged by the different engagement of gear train or planetary gear train limited discrete to provide mostly Output input speed ratio.The adjusting of wheel speed is driven then to realize by the velocity variations of internal combustion engine between two adjacent speed ratios.It is stepless Speed changer, either mechanically, one electric-type of fluid pressure type or machine, unlimited can be provided in certain speed range continuously may be used The speed ratio of selection, in theory, the velocity variations of driving wheel can be completed completely by speed changer.In this way, internal combustion engine can use up Possible work is in optimized range of speeds.Stepless transmission is compared with step change transmission simultaneously, has speed regulation steadily, can be sufficiently Many advantages, such as using internal combustion engine maximum power, therefore, stepless transmission are always pair of various countries' engineers research for many years As.
