Abstract

The invention discloses a dual-motor transverse gear-shiftable electric drive axle speed reducer assembly which comprises two motors, two gear-shifting assemblies, a planetary reduction gear assemblyand a differential mechanism assembly. The gear-shifting assemblies include a first shaft assembly and a second shaft assembly. The motors are connected with the first shaft assembly. High-speed and low-speed two-gear speed regulation is realized through a sliding meshing assembly on the first shaft assembly. The second shaft assembly is in transmission with a sun wheel axle of the planetary reduction gear assembly through a long meshing gear set. A planet carrier of the planetary reduction gear assembly is connected with a differential mechanism inner shell of the differential mechanism assembly through a planet pinion shaft. A gear ring is connected with a differential mechanism shell. The dual-motor transverse gear-shiftable electric drive axle speed reducer assembly is compact in structure, high in integrity, low in machining difficulty and light in weight.
