Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] figure 1 It is a structural schematic diagram of the first embodiment of the drive system of the hybrid electric vehicle of the present invention.

[0020] Such as figure 1 As shown, the drive system of a hybrid electric vehicle includes an engine 1, a first motor 2 mechanically connected to the engine 1, a second motor 4 connected to the first motor 1 through a first clutch 3, and a differential gear connected to the output end of the second motor 4. 6, and a battery pack 5 electrically connected to the first motor 2 and the second motor 4, wherein the first clutch 3 is an overrunning clutch.

[0021] An overrunning clutch generally comprises an outer ring, a star wheel and a roller located in the space between the outer ring and the star wheel, the roller being movable between a wedged position and a free position in the space. The o...

Abstract

The invention provides a driving system of a hybrid vehicle. The driving system comprises an engine (1), a first electric motor (2) which is in mechanical connection with the engine (1), a second electric motor (4) which is connected with the first electric machine (2) through a first clutch (3), a differential mechanism (6) which is connected with the output end of the second electric motor (4) as well as a battery (5) which is electrically connected with the first electric motor (2) and the second electric motor (4), wherein the first clutch (3) is an overrunning clutch. Because the first clutch (3) is an overrunning clutch, the hybrid vehicle can be driven independently by the second electric motor (4), or can be jointly driven by the engine (1) and / or the first electric motor (2) and the second electric motor (4) without controlling the overrunning clutch. Therefore, the operation is simplified. In addition, the volume of the overrunning clutch is relatively smaller, thereby ensuring that the hybrid vehicle has a more compact structure.

Description

technical field [0001] The invention relates to a driving system of a hybrid electric vehicle. Background technique [0002] Hybrid vehicles use two different power sources at the same time. According to the different connection methods of the power system, they can be mainly divided into three structural forms, namely series connection, parallel connection and hybrid connection. [0003] In the prior art, the hybrid vehicles of the above three structural forms have been disclosed in a large number of patent documents, such as USP 6,209,672 and the patent documents cited by the examiner in the process of examining and approving the patent (displayed in the title page of the patent) . [0004] The hybrid vehicle disclosed in USP 6,209,672 includes an engine, a clutch, a starter motor (first motor), a traction motor (second motor), a battery pack and a controller. The engine is mechanically connected to the starter motor. The combination of the engine and the starter motor ...
