Abstract

The invention discloses a method for shift and power coupling of a hybrid powered vehicle and a device thereof. Power of an engine and a motor is coupled by a bevel gear and output by an output flange; an input axis of the motor power is perpendicular to that of the engine power, and coupled by the bevel gear. The shift and power coupling device of the hybrid powered vehicle comprises a vehicle transmission, a lengthened transmission output shaft, a driven bevel gear, a drive bevel gear shaft, a motor power input flange, a coupled power output flange and the like. The engine power and the motor power are coupled by the bevel gear and output by the output flange; the input axis of the motor power is perpendicular to that of the engine power, the driving is a single-stage driving, and a drive gear switch is arranged on a gear selection shaft.

Description

technical field [0001] The patent of the present invention relates to a method and device for vehicle speed change and power coupling, especially a method and device for hybrid electric vehicle speed change and power coupling, mainly used for the speed change driven by the engine power and motor power of hybrid electric vehicles alone or jointly with the power coupling. Background technique [0002] The transmission is a commonly used variable speed transmission device in traditional vehicles. It has the characteristics of mature technology and reliable performance. However, there are some deficiencies in the existing traditional transmission vehicles, which affect the application in hybrid vehicles. The main deficiencies are: [0003] 1. Traditional automotive transmissions do not have power coupling devices and cannot be directly applied to hybrid vehicles. [0004] 2. Traditional cars cannot recover braking energy to save fuel consumption. [0005] 3. Larger engine powe...
