Transmission and preparation integration assembly for electromechanical automatic gearbox of pure electric vehicle

Abstract

The invention discloses a transmission and preparation integration assembly for an electromechanical automatic gearbox of a pure electric vehicle, belongs to the technical field of transmission and preparation integration for the electromechanical automatic gearbox of the pure electric vehicle, and mainly solves the problem of extremely high mechanical power loss of a direct drive of a hub motor of the pure electric vehicle. The transmission and preparation integration assembly is mainly characterized in that an input shaft and a permanent magnet driving motor are coaxial; an over-speed planet row sun wheel is mounted on an output section; an over-speed gear brake, an over-speed gear clutch, an over-speed gear one-way clutch, an over-speed planet row planet carrier, an over-speed planet row planet wheel and an over-speed planet row gear ring are mounted through a planet row planet carrier; a front planet row sun wheel and a rear planet row sun wheel are mounted on an input section of an output shaft; a direct gear / reverse gear clutch, a forward gear clutch, a front planet row planet wheel, a front planet row gear ring, a two-gear brake, a two-gear one-way clutch, a low / reverse gear one-way clutch, a rear planet row planet wheel and a rear planet row gear ring are mounted through a front planet row planet carrier and a rear planet row planet carrier. The transmission and preparation integration assembly has the advantages that the output power, the mechanical efficiency, the mechanical performance, the mechanical rotating speed stability and the like can be improved.

Description

technical field [0001] The invention belongs to the technical field of integration of transmission and maintenance of electromechanical automatic transmissions for pure electric vehicles, and in particular relates to an integrated assembly of transmission and maintenance of electromechanical automatic transmissions for pure electric vehicles. Background technique [0002] At present, pure electric vehicles at home and abroad are still in their infancy, and are basically produced according to the traditional in-wheel motor direct drive method. Because traditional cars use fuel engines, pure electric vehicles are powered by motors and control systems, and their spatial layout is different. The engine of a traditional car almost occupies the front working compartment, as well as the fuel tank exhaust pipe assembly and so on. The pure electric vehicle is different, it increases the installation position of the battery pack. However, in the traditional pure electric hub motor d...

Problems solved by technology

However, the traditional pure electric wheel hub motor direct drive method has a particularly large mechanical power loss when driving. When the electric vehicle starts, the mechanical power loss is even greater, and the electrical energy loss increases accordingly, resulting in energy waste.
