The new energy vehicle parallel-shaft gearbox independently developed in-house by NGC hasfeatures two different structures,: double-stage and single-stage transmission. The gearbox can be internally integrated with a differential mechanism and matched with an electronic parking mechanism and a drum brake,. withIt features such as a compact structure, a high transmission efficiency and excellent NVH performance.
1. Applying the oOrder analysis and modal analysis technology, have enabled an optimizingoptimized the gear and gearbox structure, the gearbox has afeaturing low transmission errors and an excellent NVH performance;
2.ThroughBy means of flow field simulation and thermal field simulation, and based on experimental verification, the gearbox lubricating system ishas also been optimized, with abringing high transmission efficiency and reliability ofto the gearbox;
3.Lightweight design, Bbased on finite element analysis, a lightweight design is adopted, and theensures the gearbox has a compact structure and a high power density.
