四、The performance of the open integral rear bridge and the in-package integral rear bridge
性能介绍 | ||
开式一体后桥 | 包中包一体后桥 | |
结构 | 1、靠桥管外径和车轴油封挡配合，定位可靠，使用寿命较长； 2、齿轮油装入后桥桥壳中，油量充分。齿轮运转过程，齿轮带动齿轮油，容易形成飞溅润滑，部件润滑充分； 3、内部空间充足，散热性能好。 | 1、保证铝壳整体性和密封性，减少噪音释放增加整车舒适性； 2、齿轮箱独立，便于售后拆装。 |
使用 | 承载能力较强主要适用于货运车型 | 后桥噪音略低1-2分贝，骑行舒适度提高，主要适用于乘用车型及半封闭车型。 |
五、Applicable models
1、The open integral rear axle has the advantages of strong carrying capacity and long service life in the design structure.
2、With the advantages of low noise, it is more suitable for electric three-wheeled and four-wheeled vehicles.
