Problems solved by technology

[0003] However, the inventors have found that since there is one motor in the power transmission system and the power is output to the differential through the gear reducer, the lengths of the half shafts on the left and right sides of the differential are different, and the center of gravity of the power transmission system is located at the differential. On one side of the motor, the balance of the system is poor, and it is difficult for the motor to maintain a good working range
Moreover, this one motor is the main power source. Once the motor fails, it will cause the entire power transmission system to lose power and cannot drive the vehicle to run normally.

Abstract

The invention discloses a vehicle power transmission system and a vehicle having the power transmission system. The power transmission system comprises a differential device, a main decelerator driven gear, two first electric generators, a generator power output shaft and an engine, wherein each differential device power output end is respectively connected with corresponding wheels via a half shaft; the main decelerator driven gear is mounted on the differential device; each first electric generators coaxially covers the corresponding half shaft; the main decelerator driven gear is mounted on the generator power output shaft; the two first electric generators are respectively in cooperated transmission with the generator power output shaft; and a clutch device is arranged between the engine and the differential device. Two sides of the differential device of the power transmission system are respectively provided with one first electric generator, so a gravity center of the power transmission system falls in the center of a vehicle axle; and the two first electric generators can adjust each other, so the motor is remained at an excellent work range and transmission efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power transmission system for a vehicle and a vehicle with the power transmission system. Background technique [0002] Chinese invention patent application (application number: 201010252131.0) discloses an integrated motor drive system, which includes a motor, a reducer, a differential and two transmission shafts, and two transmission shafts are connected on both sides of the differential , the motor outputs power to the differential through the reducer. The power transmission system has a relatively compact structure and a high degree of integration. [0003] However, the inventors have found that since there is one motor in the power transmission system and the power is output to the differential through the gear reducer, the lengths of the half shafts on the left and right sides of the differential are different, and the center of gravity of the power transmission syst...
