When a collision occurs, the shoulder belt tightener compensates for 「belt slack」 and 「film-reel effect」 by retracting and tightening the belt strap.
发成碰撞时,通过牵引和张紧安全带圈带,肩带张紧装置补偿安全带松动和胶片卷轴效应。
Calculation formula of the tension caused by an automatic swaying belt tightener is derived theoretically according to the force balance of stable operation of belt driving.
基于带传动在稳定工作时的受力平衡,从理论上导出了摆架式自动张紧装置所产生的张紧力的计算公式。
Take care of the original pully belt ageiging, if so please change a new belt and check the belt tightener !
安装时请检查原厂皮带老化情况,有问题请及时更换以后在使用,请检查皮带松紧力是否合适。
