Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The vehicle hybrid power system that realizes the coupling of multiple power sources provided by the invention can realize the hybrid hybrid power system with the planetary differential structure as the electromechanical coupling device, realize the electronic stepless speed change function, and control the engine to always work at the best fuel Economic zone, improve the fuel economy of the whole vehicle, realize low emission, and overcome the disadvantage that the hybrid electric vehicle relies heavily on the motor and needs a large torque and low speed motor to provide sufficient driving force.

[0034] The technical scheme of the present invention is: adopting the transmission mode of "planetary differential structure + parallel shaft", the planetary row is a planetary differential structure, including a sun gear, a planetary carrier...

Abstract

The invention belongs to a vehicle transmission, and provides a vehicle hybrid power system achieving multi-power-source coupling. The problems that as for an existing hybrid power system, a motor isexcessively large in torque and excessively low in rotating sped, and thus the system is large in size, large in weight and high in cost are solved. The vehicle hybrid power system comprises an engine, a first motor, a second motor, a speed reducer and an output flange disc; the speed reducer comprises a speed reducer box, an input shaft and an output shaft, and further comprises a one-way clutch,a planetary gear train, a first motor gear pair and a second motor gear pair which are arranged in the speed reducer box; the planetary gear train comprises a sun gear, a planetary frame, a gear ringand planetary gears; one end of the input shaft is arranged on the speed reducer box and connected with engine output, and the other end of the input shaft is arranged on the gear ring; one end of the output shaft is fixedly connected with the gear ring, the other end of the output shaft is fixedly connected with the output flange disc, and outer teeth of each planetary gear are engaged with inner teeth of the gear ring and outer teeth of the sun gear correspondingly; and a first motor passive gear is arranged on the outer side face of the gear ring, and a second motor passive gear is coaxially and fixedly connected with the sun gear.

Description

technical field [0001] The invention belongs to a vehicle transmission, in particular to a vehicle hybrid power system that realizes coupling of multiple power sources. Background technique [0002] Due to the current energy shortage and increasingly serious environmental pollution, energy saving and environmental protection have become the only way for the development of automobiles. Hybrid vehicle, as a new energy-saving and environment-friendly vehicle, is in a vigorous development stage in terms of technology and market. [0003] Compared with traditional vehicles and pure electric vehicles, the biggest difference between hybrid vehicles is the power system. For parallel and hybrid hybrid vehicles, the power coupling system is responsible for combining multiple power sources to achieve reasonable power distribution among multiple power sources and transmit the power to the drive axle. The power coupling system plays an important role in the development of hybrid electri...
