The invention is applicable to the technical field of automobile transmission, and provides a four-wheel independent hub reduction driving system applicable to formula cars, which comprises a hub connected with a rim through a rim connecting part, a brake disc connected with the outer side of the hub through a brake disc connecting part, and a planetary gear system connected with the hub through a planetary gear. And the planetary gear system is arranged in a working space arranged in the wheel edge. The transmission path integration degree of the system is high, the structure simplification degree is high, and the adopted material strength is enough. And only radial positioning of the planet gear is restrained, axial movement is allowed, and gear teeth of the planet gear cannot be broken under the condition that the lateral acceleration is 2.0 g. According to the system, a clutch, a gearbox, a differential mechanism, a half shaft and other components of a traditional driving system are abandoned, complex components of a transmission system are greatly simplified, and meanwhile light weight of the transmission system of the racing car is achieved.
本发明适用于汽车传动技术领域,提供了一种适用于方程式赛车的四轮独立轮边减速驱动系统,包括轮边,所述轮边通过轮辋连接部与轮辋连接,所述轮边的外侧通过制动盘连接部与制动盘连接,还包括:行星齿轮系统,所述行星齿轮系统安装于轮边的内部设置的工作空间中。该系统的传动路径集成程度高,结构简化程度高,采用材料强度足够。仅约束行星轮径向定位,允许轴向窜动,使行星轮在侧向2.0g加速度条件下不发生轮齿折断。该系统舍弃了传统的驱动系统的离合器、变速箱、差速器和半轴等部件,极大简化了传动系统的复杂部件,同时实现了赛车的传动系统的轻量化。
