Shell, clamp spring assembly, shaft assembly and vehicle

The utility model relates to a shell and a connecting structure thereof, the shell is used for connecting a clamp spring, the shell is provided with a clamp spring groove matched with the clamp spring, the clamp spring groove is provided with a bottom wall and a side wall, and the bottom wall and the side wall are in fillet transition. According to the shell, the clamp spring assembly, the shaft assembly and the vehicle, the stress distribution condition at the root position where the two planes of the bottom wall and the side wall of the clamp spring groove in the shell intersect can be effectively improved, the situation that due to stress concentration, the clamp spring groove is locally broken is prevented, and therefore safe and stable operation of mechanical equipment is guaranteed. 本申请涉及一种壳体及其连接结构，用于连接卡簧，壳体具有与卡簧相适配的卡簧槽，卡簧槽具有底壁和侧壁，底壁和侧壁呈圆角过渡。本申请提供的壳体、卡簧组件、轴组件和车辆，能够有效减改善壳体内卡簧槽的底壁和侧壁两平面相交的根部位置上的应力分布情况，防止出现由于应力集中而导致的卡簧槽局部断裂的情况，从而有利于保证机械设备的安全平稳运行。
