The invention discloses an all-terrain vehicle and a continuously variable transmission thereof, the continuously variable transmission comprises a main transmission mechanism, an auxiliary transmission mechanism and a transmission belt, and the auxiliary transmission mechanism is in transmission connection with the main transmission mechanism; the main transmission mechanism comprises a main shaft, a main sliding wheel assembly, a main fixed wheel assembly, a transmission belt and a brake assembly. The main fixed wheel assembly is arranged on the main shaft and fixedly connected with the main shaft. The transmission belt is at least partially located between the main sliding wheel assembly and the main fixed wheel assembly; a bearing is arranged between the transmission belt and the spindle; the brake assembly comprises a sliding piece and a positioning piece; the sliding piece is arranged between the bearing and the main shaft in the radial direction of the main shaft; the positioning piece is fixedly connected with the main shaft, and when the transmission belt rotates forwards, the transmission belt and the sliding piece rotate relatively; when the transmission belt rotates reversely, the transmission belt and the sliding part synchronously rotate relative to the fixed part and can be driven to slide towards the side close to the main sliding wheel assembly. The downhill braking scheme of the arrangement mode is safer and lower in cost.
本申请公开了一种全地形车及其无级变速器,该无级变速器包括主传动机构、从传动机构和传动带,从传动机构与主传动机构传动连接;主传动机构包括主轴、主滑动轮组件、主固定轮组件、传动带和制动组件,主固定轮组件设置在主轴上并与主轴固定连接;且传动带至少部分位于主滑动轮组件和主固定轮组件之间;传动带和主轴之间设置有轴承;制动组件包括滑动件和定位件;沿着主轴的径向上,滑动件设置在轴承和主轴之间;定位件与主轴固定连接,传动带正转时,传动带与滑动件发生相对转动;传动带反转时,传动带与滑动件相对固定件同步转动的同时能带动传动带向靠近主滑动轮组件的一侧滑移。这种设置方式的下坡制动方案更加安全且成本更低。
