Abstract

The invention provides a hybrid dynamic system, which includes an engine, a first motor, a first driving disc which drives with the engine, a first clutch of a first driven disc, a second driving disc which drives with the first motor, a second clutch of a second driven disc and deceleration assemblies which includes a high retaining gear pair, a low retaining gear pair and a deceleration output gear. The high retaining gear pair includes a high retaining driving gear and a high retaining driven gear which are mutually meshed. The high driving gear is connected with a first driven plate. The low retaining gear pair includes a lowretaining driving gear and a low retaining driven gear which are mutually meshed. The low retaining driving gear is connected with asecond driven plate. The deceleration output gear respectively and synchronously rotates with the high retaining driven gear and the low retaining driven gear.The hybrid dynamic system also includes a differential mechanism which drives with the deceleration output gear. Through setting the first clutch and the second clutch, the vehicle can meet torque and speed requirements.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid power system. Background technique [0002] In related technologies, in some hybrid power systems, there is no transmission mechanism between the engine and the motor. To meet the conditions of high torque and low speed under the starting and low speed conditions of the whole vehicle, and low torque and high speed under high speed conditions, A motor with high power and high speed is required, and the torque-speed characteristic curve of the motor needs to meet the torque and speed requirements of the vehicle under different driving conditions. Therefore, there is no speed change mechanism, and the requirements for the speed and torque characteristics of the motor are high. It affects the matching of the motor and the vehicle, and affects the performance of the new energy vehicle and the pace of progress. And there is no power interruption mechanism between the engine,...
