The invention discloses a traction suspension system of an asymmetrically-arranged elevator without a machine room, and relates to the field of elevators, the traction suspension system comprises a driving main machine, a lift car, a counterweight, a traction steel belt, a car top wheel, a counterweight wheel, rope head combinations fixed at the two ends of the traction steel belt and fixing components of the rope head combinations, and lift car main guide rails are arranged on the left side and the right side of the lift car; the total number of the traction steel belts is an odd number; the winding direction of the traction steel belt is consistent with the width direction of the lift car and is parallel to the direction of the center line of the lift car main guide rail, the traction steel belt penetrates through the lift car guide wheel on the front side and the rear side of the center line of the lift car main guide rail, and the front steel belt and the rear steel belt are asymmetrically arranged in the mode that the number of the front steel belt and the number of the rear steel belt are inconsistent. The centers of the driving main engine traction wheel, the car top wheel and the counterweight wheel are always kept consistent and axially parallel, and the lift car suspension mass center deviates a certain distance towards the single side with a large number of traction steel belts, namely, the lift car suspension mass center deviates a certain distance towards the single side with a large number of steel belts in the center of the lift car structure. Therefore, the tension of the plurality of steel belts on the car side is uniform.
本发明公开了一种非对称布置无机房电梯的曳引悬挂系统,涉及电梯领域,包括驱动主机、轿厢,对重,曳引钢带,轿顶轮及对重轮和固定在曳引钢带两端的绳头组合及其固定构件,所述轿厢左、右两侧设有轿厢主导轨,所述曳引钢带总数量为奇数;所述曳引钢带绕置方向与轿厢宽度方向一致且与轿厢主导轨中心线方向平行,所述曳引钢带在轿厢主导轨中心线的前、后两侧穿过轿厢导向轮且前、后钢带数量为不一致的非对称布置,所述驱动主机曳引轮、轿顶轮及对重轮的中心始终保持一致且轴向平行,所述轿厢悬挂质心向曳引钢带数量较多的单侧偏移一定距离,即轿厢悬挂质心向轿厢结构中心的钢带数量较多的单侧偏移一定距离,以实现轿厢侧的多根钢带的张力均匀。
