The new energy vehicle planetary gearbox for new energy vehicles independently developed in-house by NGC features two different structures, namely double-stage planetary and single-stage planetary transmission. The gearbox can be internally integrated with a differential mechanism, which features a compact structure, a high power density and an excellent NVH performance.

 

Performance Features

1. Lightweight design, based on finite element analysis, ensures the gearbox has a compact structure and a high power density. Based on finite element analysis, a lightweight design is adopted, and the gearbox has a compact structure and a high power density.

 

2. By means of flow field simulation and thermal field simulation, and based on experimental verification, the gearbox lubricating system has been optimized, resulting in high transmission efficiency and reliability of the gearbox;

 

3. Micro-gap floating uniform load technology ensures excellent load distribution between the teeth, offering an excellent NVH performance.
