Abstract

The invention relates to a power system and components of a new energy vehicle, in particular to a vehicle hybrid drive system. The present invention adds a hollow input shaft and a hollow intermediate shaft on the basis of the traditional three-shaft gearbox, and combines the motor, the coupling mechanism and the engine to form a brand-new hybrid drive system; the system can ensure dual power The vehicle can be automatically shifted to drive the vehicle by a single power source, and it can also be guaranteed to automatically change gears to drive the vehicle when the dual power source is hybrid driving; and on the premise of not reducing the number of gears of each power source, each power source can be optimally matched according to its own efficiency zone. Different gear speed ratios; at the same time, it also solves the problem of power interruption in gear shifting. When one of the power units drives the vehicle to change gears, the other power unit performs power compensation, so that the power is not interrupted when shifting gears, effectively improving driving comfort.

Description

technical field [0001] The invention relates to a power system and components of a new energy vehicle, in particular to a vehicle hybrid drive system. Background technique [0002] New energy vehicles are rapidly developing in the industry due to their energy saving and environmental protection features. This type of vehicle will definitely change the existing energy structure. As an important branch of new energy vehicles, hybrid electric vehicles give full play to the advantages of electric motors on the basis of retaining traditional engines, and greatly improve vehicle fuel economy and emissions. Hybrid electric vehicles have price advantages and endurance advantages that pure electric vehicles do not have, so the development and promotion of hybrid power systems is imperative. As one of the key technologies of the hybrid power system, the power coupling system has been researched all the time, but there are few breakthroughs in domestic research lacking the technical f...
