The tensioning device comprises a tensioning seat, a tensioning screw rod, a tensioning piece and a tensioning wheel, the tensioning seat is fixedly arranged, the tensioning screw rod is arranged on the tensioning seat in the mode that the tensioning screw rod can rotate in a single-freedom-degree reciprocating mode in the circumferential direction, and the tensioning wheel is arranged on the tensioning piece. The tensioning piece is arranged on the tensioning screw in a threaded fit mode and can be driven by the tensioning screw to reciprocate in the tensioning direction of the motorcycle transmission belt or the transmission chain. The tensioning wheel is arranged on the tensioning piece in a running fit mode and is in tensioning fit with the transmission belt or the transmission chain. The tensioning structure driven by threads is adopted, the tensioning state is adjusted through threaded connection, the structure is simple, cost is low, adjustment is easy, the stable tensioning effect is achieved, and therefore it is guaranteed that the transmission belt or the transmission chain is kept in the optimal working state for a long time.
本发明公开了一种张紧装置及倒三轮电动摩托车,包括张紧座、张紧螺杆、张紧件和张紧轮,张紧座固定设置,张紧螺杆以可在圆周方向单自由度往复转动的方式设置在张紧座,张紧件螺纹配合设置于张紧螺杆且可被张紧螺杆驱动沿摩托车传动带或传动链张紧的方向往复运动;张紧轮转动配合设置于张紧件并与传动带或传动链形成张紧配合;本发明采用螺纹驱动的张紧结构,通过螺纹连接并调整张紧状态,结构简单,成本较低,且易于调节,具有稳定的张紧效果,从而保证传动带或传动链长期保持最佳的工作状态。
