Hybrid vehicle and power coupling system integration device thereof

Abstract

The invention discloses a power coupling system integration device. A separation clutch and a motor stator and rotor are highly integrated with an outer clutch hub of a first clutch and a transmissionshaft of a first clutch, and through a casing sealing cover plate, it is ensured that lubricating oil liquid in a whole system is sealed in a sealed chamber composed of the casing sealing cover plateand a transmission front casing. The separation clutch ensures engagement and separation and lubrication through a pressure oil line and a lubricating oil line which are disposed on the transmissionshaft of the first clutch, so that power from an engine is effectively transmitted. The motor stator and rotor are cooled through a cooling water jacket and lubricating oil passing through the separation clutch, the first clutch and a second clutch, and the cooling effect is ensured. According to the power coupling system integration device, through a highly integrated design, a power coupling system device and the double clutches are integrated in the transmission front casing. The axial dimension of the entire transmission is effectively shortened, and all functions required by a hybrid power are achieved. The invention also discloses a hybrid vehicle.

Description

technical field [0001] The invention relates to the technical field of a hybrid electric vehicle power coupling system, in particular to a power coupling system integration device and a hybrid electric vehicle. Background technique [0002] In recent years, various power coupling system devices for hybrid electric vehicles have emerged in an endless stream, including power split devices such as Japan's Toyota, American GM, and China's Corun, etc., and dual-motor series-parallel devices such as GAC's split-axis four-wheel drive, Honda Accord, and Mitsubishi. Outlander, etc., single-motor parallel devices such as Volkswagen Touareg, BMW 5 Series, Mercedes-Benz S500, etc. These devices are equipped with an engine and a motor device, and try to avoid the engine working in the low-efficiency range. The low-speed stage is mainly driven by the motor. Among them, the power splitting device and the series-parallel device need to re-develop a new gearbox-specific device separately, wh...

Problems solved by technology

[0003] In the known arrangement, the motor and the separation clutch are integrated separately and connected as a module with various automatic transmissions, including dual-clutch transmissions, automatic transmissions, continuously variable transmissions, etc. This arrangement does not require The transmission mechanism of the transmission is greatly modified and modified, but the axial length is increased (not suitable for front-drive vehicles), and it is only suitable for mid-to-high-end cars and SUVs with rear-drive forms, which limits the application of front-drive models and the system the popularity of
