Vehicle power transmission system and vehicle having power transmission system

Abstract

The invention discloses a vehicle and a vehicle power transmission system of the vehicle. The power transmission system comprises a differential device, two first electric generators, a first input shaft, a second input shaft, an output shaft and a second electric generator, wherein each differential device power output end is respectively connected with corresponding wheel vehicles via a half shaft; the two first electric generator are arranged on two sides of the differential device; the first and second input shafts are coaxially sleeved to each other; an engine is configured to be joined with at least one input shaft of the first and second input shafts; the output shaft is in cooperative transmission with the first and second input shafts; an output shaft output gear engaged with a main decelerator driven gear covers the output shaft; a synchronizer is arranged on the output shaft to join the output shaft output gear; the two first electric generators are in cooperative transmission with the output shaft; and the second electric generator is in cooperative transmission with the main decelerator driven gear. 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.

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...

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.
