Hybrid power system and vehicle

Abstract

The invention relates to the field of vehicles, in particular to a hybrid power system and a vehicle. The input side of a planetary decelerating mechanism of the hybrid power system is in transmissionconnection with an engine, a center input shaft of a gearbox is in transmission connection with the output end of a main driving motor, a center output shaft of the planetary decelerating mechanism is in coaxial connection with a center output shaft of the gearbox, a connecting end in transmission connection with an axle is arranged, and the center input shaft and the center output shaft of the gearbox are in transmission connection through a gear shifting mechanism located on the radial side position. The gear shifting mechanism of the gearbox of the hybrid power system is located on the radial side position of the center input shaft, the coaxial connection between the gearbox and the main driving motor through the center output shaft is easily ensured, the gear shifting mechanism is located in the gearbox, during machining, a gearbox manufacture controls machining precision, and the aim is easily achieved. Machining and assembling precision is ensured, and machining and assembling cost is reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a hybrid power system and a vehicle using the hybrid power system. Background technique [0002] With the gradual depletion of mineral resources, more and more new energy applications appear in people's lives, and new energy vehicles are widely used as a new energy product. New energy vehicles are divided into two types: pure electric and hybrid, and the two vehicles use different transmission systems due to different sources of power output. Taking hybrid vehicles as an example, the Chinese utility model patent with application number 201620334918.4 and authorized announcement number CN205706147U discloses a hybrid system and a hybrid vehicle using the system. The disclosed hybrid system includes a planetary row and a gearbox connected in series. The planetary row is connected to the rear side of the engine, and the gearbox is connected to the rear side of the planetary row and is conne...
