Embodiment Construction

[0068] Attached below figure 1 Specific embodiments of the present invention will be described in detail. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0069] The input shafts of the engine E1, the motor M1 and the one-way clutch C1 are coaxial, and the power shafts are fixedly connected.

[0070] The output shaft of the one-way clutch C1 is connected to the transmission shaft A1.

[0071] Gear G11 and gear G12 are set on the transmission shaft A1, and the synchronizer S1 is fixedly connected to the transmission shaft A1. The synchronizer S1 can not be connected to any gear through a sliding sleeve, or can be connected to one of the gears G11 or G12, a total of three state.

[0072] The motor M2 is coaxial with the transmission shaft A3, and the power shaft is fixedly connected.

[0073] Gear G31 and gear G32 are set on the transmission shaft A3, and the synchronizer S2 is fixe...

Abstract

The invention provides a hybrid electric vehicle system based on a one-way clutch, belongs to the technical field of transportation machinery. The hybrid electric vehicle system is a shifting fork synchronizer gear shifting and speed changing mechanism based on the one-way clutch. The system is composed of an engine E1, a motor M1, a one-way clutch C1, a transmission shaft A1, a gear G11, a synchronizer S1, a gear G12, a transmission shaft A2, a gear G21, a gear G22, a gear G23, a gear G24, a motor M2, a transmission shaft A3, a gear G31, a synchronizer S2, a gear G32, a gear G41, a differential D1, a half shaft A4 and a half shaft A5. The one-way clutch C1 is used for achieving power decoupling of the gear shifting action of the transmission shaft A1. The vehicle system has nine working modes, can adapt to all working conditions required by vehicle running, can enable the engine to always work in the optimal fuel consumption rate interval, has independently designed climbing performance, low-speed acceleration performance and high-speed driving performance, supports unpowered interruption gear shifting and supports energy recovery.

Description

technical field [0001] The invention belongs to the technical field of transportation machinery, and in particular relates to a hybrid electric vehicle system based on a one-way clutch. Background technique [0002] In practical applications, gasoline-electric hybrid vehicles have been proven to be one of the most energy-efficient, environmentally friendly, and most mature and stable vehicle models at this stage. The design of a gasoline-electric hybrid vehicle not only adopts the traditional vehicle design method, but also introduces the structural elements of the vehicle power system. Therefore, how to design a set of reasonable transmission structure and corresponding control strategy, so that the vehicle can achieve the best fuel economy under any working conditions, is the technical core of developing gasoline-electric hybrid vehicles. [0003] In domestic hybrid electric vehicle research, many excellent hybrid electric vehicle structures have appeared. The competitio...
