Problems solved by technology

However, since the lubricant reduces the coefficient of friction of the friction surface, energy is lost in the lubricant
Typically, wet clutches consist of a stack of multiple clutch plates in order to compensate for the low coefficient of friction of the wet surfaces, which results in less efficient shifting

Abstract

A transmission device of a vehicle hybrid power system is arranged between two power sources, one of the two power sources is an engine, the other power source is a motor, and the transmission devicecomprises a fixed box body, a planetary gear mechanism and a dry-type double-clutch module, wherein a planetary gear train is arranged in the box body and comprises a sun gear, a gear ring coaxially arranged around the sun gear, at least one planetary gear meshed between the sun gear and the gear ring, and a planet carrier for bearing the planetary gears, and the sun gear is connected with the output shaft of the first power source; the dual-clutch module includes a clutch housing and first and second clutches disposed in the clutch housing. The clutch housing is connected with the output shaft of the second power source and fixedly connected with the gear ring, the planet carrier forms the power output end of the transmission device, the first clutch establishes a joint and separation state between the planet carrier and the clutch housing, and the second clutch establishes a joint and separation state between the clutch housing and the box body.

Description

technical field [0001] The present application relates to a vehicle hybrid system with a transmission consisting of a planetary gear and a dual clutch module. Background technique [0002] Hybrid electric vehicles, including gasoline-electric hybrid vehicles (HEV) and plug-in hybrid electric vehicles (PHEV), are considered to be the most promising means of transportation in the medium and long term. In the field of hybrid vehicles, planetary gear mechanisms are widely used as electromechanical power coupling mechanisms, such as in parallel hybrid systems equipped with conventional automatic transmissions, power-split hybrid transmissions, and other dedicated hybrid transmissions. At present, the hybrid system mainly uses a single motor or a dual motor as a power source, and uses complex wet clutch elements and planetary gear mechanisms or gear pairs. [0003] For example, patent document CN104786817A discloses a transmission device for a hybrid electric vehicle, which inclu...
