The invention provides a two-wheel and four-wheel drive switching protection structure of an all-terrain vehicle. An elastic supporting structure is arranged at the shifting end of a shifting sleeve shifting rod; when a spline shifting sleeve is engaged and clamped, and after a bridge motor is driven in place, the shifting end of the shifting sleeve shifting rod deforms through an elastic supporting structure, and meshing impact caused by rigid connection is reduced; and meanwhile, the elastic supporting structure provides continuous pushing force for the shifting sleeve shifting block, afterthe spline shifting sleeve corresponds to the half axle gear in position, the elastic supporting structure pushes the spline shifting sleeve in place through the elastic pushing force of the elastic supporting structure, the shifting end of the shifting sleeve shifting rod returns to a normal station, and the driving safety of the axle motor in the two-wheel and four-wheel drive state switching process of the all-terrain vehicle is improved. The invention further provides an all-terrain vehicle.
本发明提供了一种全地形车二四驱切换保护结构,将拨套拨杆的拨动端设置弹性支撑结构,当花键拨套出现啮合卡滞时,桥用电机驱动到位后,拨套拨杆的拨动端通过弹性支撑结构形变,减少刚性连接造成啮合冲击,同时,弹性支撑结构提供拨套拨块持续的推动力,当花键拨套和半轴齿轮位置对应后,弹性支撑结构由其弹性推动力将花键拨套推送到位,拨套拨杆的拨动端回复至正常工位,提高桥用电机对全地形车二四驱状态切换过程中的驱动安全性。本发明还提供了一种全地形车。
